Description

i DK 168637 B1in DK 168637 B1

Den foreliggende opfindelse angår ikke-vandige flydende stof-behandl ingsmidler. Nærmere betegnet angår opfindelsen ikke-vandige flydende tøjvaskemidler, som er stabile mod faseadskillelse og gelering og er let hældelige samt anvendelsen af 5 disse midler til rensning af snavsede stoffer.The present invention relates to non-aqueous liquid substance treating agents. More particularly, the invention relates to non-aqueous liquid laundry detergents which are stable to phase separation and gelling and are readily pourable and to the use of these agents for the purification of soiled substances.

Flydende ikke-vandige kraftigt virkende tøjvaskemidler er velkendte. Midler af denne type kan f.eks. omfatte et flydende ikke-ionisk overfladeaktivt stof, hvori der er dispergeret partikler af en builder, som vist f.eks. i US-patentskrifterne 10 nr. 4.316.812, 3.630.929 og 4.264.466 og GB-patentskrifterne nr. 1.205.711, 1.270.040 og 1.600.981.Liquid non-aqueous powerful laundry detergents are well known. Funds of this type can e.g. comprising a liquid nonionic surfactant containing dispersed particles of a builder, as shown e.g. in U.S. Patents Nos. 4,316,812, 3,630,929 and 4,264,466, and U.S. Patent Nos. 1,205,711, 1,270,040, and 1,600,981.

Flydende rensemidler anses ofte for at-være mere bekvemme at anvende end tørre pulverformede eller partikelformede produkter og er derfor blevet foretrukket af forbrugerne. De er let-15 te at måle, opløses hurtigt i vaskevandet, kan let anvendes i koncentrerede opløsninger eller dispersioner på snavsede områder af tøj, der skal vaskes, og de er ikke støvende, og de optager i reglen mindre lagerplads. Desuden kan de flydende rensemidler have inkorporeret i deres sammensætning materialer, 20 som ikke kunne tåle tørringer uden ødelæggelse, hvilke materialer ofte er ønskelige ved fremstilling af partikelformede rensemiddelprodukter. Selv om de har mange fordele frem for enhedsprodukter eller partikelformede faste produkter, har flydende rensemidler ofte visse iboende ulemper, der må over-25 vindes for at fremstille acceptable industrielle rensemiddel-proukter. Nogle produkter skiller således ved lagring og andre skiller ved afkøling og gendispergeres ikke let. I nogle tilfælde ændres produktets viskositet og det bliver enten for tykt til at hælde eller så tyndt, at det virker vandagtigt.Liquid cleansers are often considered to be more convenient to use than dry powdered or particulate products and have therefore been preferred by consumers. They are easy to measure, dissolve quickly in the wash water, can easily be used in concentrated solutions or dispersions on dirty areas of clothing to be washed, and are not dusty and usually take up less storage space. Furthermore, the liquid detergents may have incorporated in their composition materials which could not withstand drying without destruction, which materials are often desirable in the manufacture of particulate detergent products. Although they have many advantages over unit products or particulate solid products, liquid detergents often have certain inherent disadvantages that must be overcome to produce acceptable industrial detergent products. Thus, some products separate on storage and others on cooling and do not readily disperse. In some cases, the viscosity of the product changes and it becomes either too thick to pour or so thin that it seems watery.

30 Nogle klare produkter bliver uklare og andre gelerer ved henstand.30 Some clear products become fuzzy and some gels on standing.

De foreliggende opfindere har derfor undersøgt adfærden af ikke-ioniske flydende overfladeaktive systemer med partikel-formet stof suspenderet deri. Af særlig interesse har været DK 168637 B1 2 ikke-vandige builderholdige flydende tøjvaskemidler og problemet med udfældning af den suspenderede builder og andre vaskemiddeladditiver samt problemet med gelering, der står i forbindelse med ikke-ioniske overfladeaktive stoffer. Disse 5 overvejelser har en betydning for f.eks. produktets stabilitet, hældelighed og dispergerbarhed.The present inventors have therefore investigated the behavior of non-ionic liquid surfactant systems with particulate matter suspended therein. Of particular interest have been DK 168637 B1 2 non-aqueous builder-containing liquid laundry detergents and the problem of precipitation of the suspended builder and other detergent additives as well as the problem of gelling associated with non-ionic surfactants. These 5 considerations have a bearing on e.g. the stability, pourability and dispersibility of the product.

Det er kendt at et af hovedproblemerne med builderholdige flydende tøjvaskemidler er deres fysiske stabilitet. Dette problem kommer af at vægtfylden af de faste partikler dispergeret 10 i det ikke-ioniske flydende overfladeaktive stof er højere end vægtfylden af det flydende overfladeaktive stof.It is known that one of the main problems with builder-containing liquid laundry detergents is their physical stability. This problem is because the density of the solid particles dispersed 10 in the nonionic liquid surfactant is higher than the density of the liquid surfactant.

De dispergerede partikler har derfor en tendens til at fælde ud. Der findes to principielle løsninger til løsning af udfældningsproblemet: forøgelse af den ikke-ioniske væskes vis-15 kositet og reduktion af partikelstørrelsen af det dispergerede faste stof.Therefore, the dispersed particles tend to precipitate. There are two basic solutions to solve the precipitation problem: increasing the viscosity of the non-ionic liquid and reducing the particle size of the dispersed solid.

Det er kendt at suspensioner kan stabiliseres mod udfældning ved at tilsætte uorganiske eller organiske fortykkelsesmidler eller dispergeringsmidler, som f.eks. uorganiske materialer 20 med meget højt overfladeareal, f.eks. findelte siliciumdiox-ider, lerarter osv., organiske fortykkelsesmidler, såsom cel-luloseetherne, acrylpolymerer og acrylamidpolymerer, polyelek-trolytter osv. Disse forøgelser af suspensionens viskositet er naturligt begrænset af det krav, at den flydende suspension 25 skal være let hældelig og strømmelig, selv ved lav temperatur. Endvidere bidrager disse additiver ikke til præparatets renseevne .It is known that suspensions can be stabilized against precipitation by adding inorganic or organic thickeners or dispersants, such as e.g. inorganic materials 20 with very high surface area, e.g. finely divided silica, clays, etc., organic thickening agents such as the cellulose ethers, acrylic polymers and acrylamide polymers, polyelectrolytes, etc. These increases in the viscosity of the suspension are naturally limited by the requirement that the liquid suspension be easily pourable and flowable. even at low temperature. Furthermore, these additives do not contribute to the purity of the preparation.

tt

Formaling for at reducere partikelstørrelsen giver følgende fordele: 30 1. Det specifikke overfladeareal af de dispergerede partikler stiger, og partikelbefugtningen med den ikke-vandige bærer (flydende ikke-ionisk stof) forbedres proportionalt.Grinding to reduce particle size provides the following advantages: 1. The specific surface area of the dispersed particles increases and the particle wetting with the non-aqueous carrier (liquid non-ionic substance) improves proportionally.

DK 168637 B1 3 2. Gennemsnitsafstanden mellem dispergerede partikler reduceres med en proportional stigning i reaktionen partikelpartikel. Hver af disse virkninger bidrager til at forøge restgelstyrken og suspensionens flydespænding samtidigt med, at 5 formaling betydeligt nedsætter den plastiske viskositet.DK 168637 B1 3 2. The average distance between dispersed particles is reduced by a proportional increase in the particle particle reaction. Each of these effects contributes to increasing the residual gel strength and the liquid yield stress of the suspension while significantly reducing the plastic viscosity.

Flyde spændingen defineres som den minimale spænding der er nødvendig for at inducere en plastisk deformation (strømning) af suspensionen. Når man således forestiller sig suspensionen som et løst netværk af dispergerede partikler, vil suspensio-10 nen opføre sig som en elastisk gel og der vil ikke ske nogen plastisk strømning, hvis den påførte spænding er mindre end flydespændingen. Når først flydespændingen er overvundet, brydes netværket på nogle punkter og prøven begynder at strømme, men med en meget høj tilsyneladende viskositet. Hvis for-15 skydnings spændingen er meget større end flydespændingen, bliver pigmenterne delvis forskydnings-deflokkuleret og den tilsyneladende viskositet falder. Endelig, hvis forskydningsspændingen er meget højere end flydespændingen, bliver de dispergerede partikler fuldstændigt forskydnings-deflokkuleret og 20 den tilsyneladende viskositet er meget lav, som om der ikke var nogen indbyrdes reaktion mellem partiklerne.The float stress is defined as the minimum stress required to induce a plastic deformation (flow) of the suspension. Thus, when the suspension is imagined as a loose network of dispersed particles, the suspension will behave like an elastic gel and no plastic flow will occur if the applied voltage is less than the flow stress. Once the flow voltage is overcome, the network breaks at some points and the sample begins to flow, but with a very high apparent viscosity. If the shear stress is much greater than the yield stress, the pigments are partially shear-deflocculated and the apparent viscosity decreases. Finally, if the shear stress is much higher than the flow stress, the dispersed particles become completely shear-deflocculated and the apparent viscosity is very low, as if there was no reaction between the particles.

Jo højere flydespændingen af suspensionen er, des højere er derfor den tilsyneladende viskositet ved lav forskydningshastighed og des bedre er den fysiske stabilitet mod udfældning 25 af produktet.Therefore, the higher the flow stress of the suspension, the higher the apparent viscosity at low shear rate and the better the physical stability against precipitation of the product.

Foruden problemet med udfældning eller faseseadskillelse, lider de ikke-vandige flydende tøjvaskemidler baseret på flydende ikke-ioniske overflådeaktive stoffer af den ulempe, at de ikke-ioniske stoffer er tilbøjlige til at gelere, når de 30 sættes til koldt vand. Dette er et særligt vigtigt problem ved den sædvanlige anvendelse af europæiske automatiske husholdningsvaskemaskiner, hvor brugeren anbringer tøjvaskemidlet i et dispenseringsaggregat (f.eks. en skuffe) i maskinen. Under maskinens drift udsættes rensemidlet i dispenseringsaggregatet DK 168637 B1 4 for en strøm af koldt vand for at overføre det til hovedmassen af vaskeopløsningen. Især i vintermånederne, når rensemidlet og vandet, der føres til dispenseringsaggregatet, er særligt kolde, vokser rensemidlets viskositet udtalt og der dannes en 5 gel. Som følge heraf bliver noget af midlet ikke skyllet fuldstændigt af dispenseringsaggregatet under maskinens drift, og en aflejring af midlet opbygges i gentagne vaskeperioder og kræver til slut, at brugeren skyller dispenseringsaggregatet med varmt vand.In addition to the problem of precipitation or phase separation, the non-aqueous liquid laundry detergents based on liquid nonionic surfactants suffer from the disadvantage that the nonionic substances are prone to gelling when added to cold water. This is a particularly important problem in the usual use of European automatic household washing machines, where the user places the laundry detergent in a dispensing unit (eg a drawer) in the machine. During the operation of the machine, the detergent in the dispensing unit DK 168637 B1 4 is subjected to a stream of cold water to transfer it to the main mass of the washing solution. Especially in the winter months, when the detergent and water supplied to the dispensing unit are particularly cold, the viscosity of the detergent increases markedly and a 5 gel is formed. As a result, some of the agent is not completely rinsed by the dispensing unit during machine operation, and a deposition of the agent is built up in repeated washing periods and finally requires the user to rinse the dispenser with hot water.

10 Gelerings fænomenet kan også være et problem, når man ønsker at udføre vask under anvendelse af koldt vand, således som det kan anbefales til visse syntetiske og sarte stoffer eller stoffer, der kan krybe i varmt vand.The gelation phenomenon can also be a problem when one wishes to perform washing using cold water, as recommended for certain synthetic and delicate substances or substances that can crawl in hot water.

Tendensen hos koncentrerede rensemidler til at gelere under 15 lagring forværres ved lagring åf midlerne i uopvarmede lagerområder eller ved forsendelse af midlerne i vintermånederne i uopvarmede transportorganer.The tendency of concentrated detergents to gel under storage is exacerbated by storage of the agents in unheated storage areas or by shipping the agents in the winter months in unheated transport means.

Delvise løsninger på geleringsproblemet er blevet foreslået, f.eks. ved at fortynde det flydende ikke-ioniske stof med 20 visse viskositetsregulerende opløsningsmidler og gelhindrende midler, såsom lavere alkanoler, f.eks. ethylalkohol (se US-patent nr. 3.953.380), alkalimetalformiater og adipater (se US-patent nr. 4.368.147), hexylenglycol, polyethylenglycol, osv., og ved strukturmodifikation og optimering af det ikke-25 ioniske stof. Som et eksempel på modifikation af ikke-ionisk overfladeaktivt stof har et særligt godt resultat været opnået ved at syrne hydroxylmolekylenden af det ikke-ioniske molekyle. Fordelene ved at indfore en carboxylsyre i enden af det ikke-ioniske stof indbefatter gelhæmning ved fortynding, ned-30 sættelse af hældepunktet for det ikke-ioniske stof, og dannelse af et anionisk overfladeaktivt stof. når det neutraliseres i vaskevæsken. Strukturoptimering af det ikke-ioniske stof har været centreret om kædelængden af den hydrofobe-lipo-file molekyldel og antallet og opbygningen af alkylenoxid DK 168637 B1 5 (f.eks. ethylenoxid) enheder i den hydrofile molekyldel. For eksempel har det vist sig at en C13 fedtalkohol ethoxyleret med 8 mol ethylenoxid kun viser begrænset tendens til geldannelse.Partial solutions to the gelation problem have been proposed, e.g. by diluting the liquid nonionic substance with certain viscosity regulating solvents and gel inhibitors such as lower alkanols, e.g. ethyl alcohol (see U.S. Patent No. 3,953,380), alkali metal formates and adipates (see U.S. Patent No. 4,368,147), hexylene glycol, polyethylene glycol, etc., and by structural modification and optimization of the nonionic substance. As an example of modification of nonionic surfactant, a particularly good result has been obtained by acidifying the hydroxyl molecule end of the nonionic molecule. The advantages of introducing a carboxylic acid into the end of the nonionic substance include gel inhibition by dilution, lowering the pour point of the nonionic substance, and formation of an anionic surfactant. when neutralized in the wash liquid. Structural optimization of the nonionic substance has been centered on the chain length of the hydrophobic lipophilic moiety and the number and structure of alkylene oxide (eg ethylene oxide) units in the hydrophilic moiety. For example, it has been found that a C13 fatty alcohol ethoxylated with 8 moles of ethylene oxide shows only a limited tendency for gelling.

5 Alligevel er forbedringer ønskede med hensyn til både stabilitet og gelhæmning af ikke-vandige flydende stofbehandlings-midler.Nevertheless, improvements in both stability and gel inhibition of non-aqueous liquid drug treatment agents are desired.

Ifølge den foreliggende opfindelse fremstilles et højt koncentreret stabilt ikke-vandigt flydende tøjvaskemiddel ved til 10 midlet at sætte små effektive mængder af et antiudfældende og stabiliserende urinstofadditiv som antiudfældende og stabiliserende additiv.According to the present invention, a highly concentrated stable non-aqueous liquid laundry detergent is prepared by adding to the agent small effective amounts of an anti-precipitating and stabilizing urea additive as anti-precipitating and stabilizing additive.

Midlerne ifølge opfindelsen indeholder som en væsentlig bestanddel et antiudfældende og stabiliserende urinstofadditiv 15 som antiudfældende og stabiliserende additiv.The agents of the invention contain as an essential component an anti-precipitating and stabilizing urea additive as anti-precipitating and stabilizing additive.

Det antiudfældende stabiliserende urinstofadditiv antages at virke i rensemidlet som et overfladeaktivt middel, der gør phosphatbuilderen mere forenelig med den ikke-ioniske overfladeaktive detergent.The anti-precipitating stabilizing urea additive is believed to act in the detergent as a surfactant which makes the phosphate builder more compatible with the nonionic surfactant detergent.

20 Urinstoffet antages at reagere med de anioniske phosphatbuil-dersalte, således at det gør buildersaltene mere forenelige med det ikke-ioniske overfladeaktive stof og forbedre kontakten mellem buildersaltene og ikke-ionisk overfladeaktivt stof. Forbedringen i kontakten mellem phosphatet og det ikke-ioniske 25 overfladeaktive stof forøger stabiliteten af phosphatsuspen-sionen i det ikke-ioniske'overfladeaktive middel.The urea is believed to react with the anionic phosphate builder salts to make the builder salts more compatible with the nonionic surfactant and improve contact between the builder salts and nonionic surfactant. The improvement in contact between the phosphate and the nonionic surfactant increases the stability of the phosphate suspension in the nonionic surfactant.

Selv når urinstofforbindelsen sættes til midlet i små mængder, forbedrer den dispergerbarheden af suspensionen af buildersalt ved at virke til hindring af geldannelse af suspensionen af 30 buildersalt.Even when the urea compound is added to the agent in small amounts, it improves the dispersibility of the builder salt suspension by preventing gelling of the builder salt suspension.

DK 168637 B1 6DK 168637 B1 6

Urinstoffet forbedrer dispergerbarheden ved at hindre geldannelse af suspensionen af buildersaltpartikler, når der sættes vand til midlet, f.eks. i dispenseringsaggregatet i en opvaskemaskine og/eller når midlet sættes til vand.The urea improves dispersibility by preventing gelling of the suspension of builder salt particles when water is added to the agent, e.g. in the dispensing unit in a dishwasher and / or when the agent is added to water.

5 Urinstofforbindelsen, der anvendes i midlerne ifølge opfindelsen, har formlen H2NCONH2- Urinstoffet danner en tautomer, der har formlen H2NCNHOH, som kaldes carbamid.The urea compound used in the compositions of the invention has the formula H2NCONH2. The urea forms a tautomer having the formula H2NCNHOH called carbamide.

For at forbedre viskositetsegenskaberne af midlet kan der tilsættes et syreafsluttet ikke-ionisk overfladeaktivt stof. For 10 yderligere at forbedre viskositetsegenskabeme af midlet og lageregenskabeme af midlet kan der tilsættes viskositetsforbedrende og antigeleringsmidler, såsom alkylenglycoler, poly-alkylenglycoler og alkylenglycolirtonoalkylethere, og yderligere antiudfældningsmidler, såsom phosphorsyreester og/eller alumi-15 niumstearat. I en udførelsesform ifølge opfindelsen indeholder rensemidlet et syreafsluttet ikke-ionisk overfladeaktivt stof, en alkylenglycolmonoalkylether og et urinstof antiudf ældnings -middel og stabiliseringsmiddel.To improve the viscosity properties of the agent, an acid-terminated nonionic surfactant may be added. To further improve the viscosity properties of the agent and the storage properties of the agent, viscosity enhancers and anti-gelling agents such as alkylene glycols, polyalkylene glycols and alkylene glycol pyrtonoalkyl ethers may be added, and additional anti-precipitating agents such as phosphoric acid ester and / or aluminum stearate. In one embodiment of the invention, the detergent contains an acid-terminated nonionic surfactant, an alkylene glycol monoalkyl ether, and a urea anti-precipitant and stabilizer.

Hygiejnemidler eller blegemidler og aktivatorer derfor kan 20 tilsættes for at forbedre de blegende og rensende egenskaber af midlet.Hygiene or bleaching agents and activators can therefore be added to improve the bleaching and cleansing properties of the agent.

I en udførelsesform ifølge opfindelsen er builderkomponenterne af midlet formalet til en partikelstørrelse mindre end 100 μτη og fortrinsvis mindre end 10 μτη for yderligere at forbedre 25 stabiliteten af' suspensionen af builderkomponenterne i det flydende ikke-ioniske overfladeaktive rensemiddel.In one embodiment of the invention, the builder components of the agent are ground to a particle size less than 100 μτη and preferably less than 10 μτη to further improve the stability of the suspension of the builder components in the liquid nonionic surfactant cleaner.

Desuden kan andre bestanddele sættes til midlet, såsom antiin-krustationsmidler, antiskummemidler, optiske klaringsmidler, enzymer, midler til hindring af genaflejring af snavs, parfume 30 og farvestoffer.In addition, other ingredients may be added to the agent such as anti-crustaceans, anti-foaming agents, optical cleaners, enzymes, dirt repellents, perfumes 30 and dyes.

De for tiden fremstillede vaskemaskiner til husholdningsbrug DK 168637 B1 7 arbejder normalt ved vaske temperaturer op til 95 °C. Ca. 20 liter vand anvendes i vaskeperioden og skylleperioden.The currently manufactured washing machines for domestic use DK 168637 B1 7 normally operate at washing temperatures up to 95 ° C. Ca. 20 liters of water is used during the wash and rinse period.

Normalt anvendes ca. 200 - 250 g pulverformet rensemiddel pr. vask.Usually approx. 200 - 250 g powdered detergent per wash.

5 Ifølge den foreliggende opfindelse, hvor der anvendes højt koncentreret flydende rensemiddel, kræves der normalt kun 100 g (78 cm^) af det flydende rensemiddel for at vaske en fuld ladning af snavset tøj .According to the present invention, where highly concentrated liquid detergent is used, only 100 g (78 cm 2) of the liquid detergent is usually required to wash a full load of soiled clothing.

En side af opfindelsen angiver derfor et flydende kraftigt 10 virkende tøjvaskemiddel sammensat af en suspension af et buildersalt eller af et anionisk buildersalt, f.eks. et phosphat-buildersalt, i et flydende ikke-ionisk overfladeaktivt stof, hvori midlet indbefatter en effektiv mængde af en urinstofforbindelse til at forøge stabiliteten af suspensionen mod ud-15 fældning og dispergerbarheden af suspensionen i vand.Therefore, one aspect of the invention discloses a liquid powerful laundry detergent composed of a suspension of a builder salt or of an anionic builder salt, e.g. a phosphate builder salt, in a liquid nonionic surfactant, wherein the agent includes an effective amount of a urea compound to enhance the stability of the suspension against precipitation and the dispersibility of the suspension in water.

I en anden udførelses form angiver opfindelsen et koncentreret flydende kraftigt virkende tøjvaskemiddel som er stabilt, ikke-udfældende ved lagring og ikke-gelerende ved lagring og brug. De flydende midler ifølge opfindelsen er let hældelige, 20 kan let måles og let fyldes i vaskemaskinen.In another embodiment, the invention discloses a concentrated liquid powerful laundry detergent which is stable, non-precipitating upon storage and non-gelling upon storage and use.

Tilsætningen af urinstofforbindelsen til rensemidlerne reducerer problemet med udfældning af dispergerede partikler og faseadskillelse og forbedrer dispergerbarheden af de suspenderede rensemiddelpartikler i vand.The addition of the urea compound to the detergents reduces the problem of precipitating dispersed particles and phase separation and improves the dispersibility of the suspended detergent particles in water.

5 De koncentrerede ikke-vandige flydende ikke-ioniske overfladeaktive tøjvaskemidler ifølge opfindelsen har fordelene af at være stabile, ikke-udfældende ved lagring og ikke-gelerende ved lagring. De flydende midler er let hældelige, kan let måles og let kommes i tøivaskemaskiner.The concentrated non-aqueous liquid nonionic surfactant laundry detergents of the invention have the advantage of being stable, non-precipitating upon storage and non-gelling upon storage. The liquid agents are easily pourable, can be easily measured and easily put into laundry machines.

10 Det er et formål med den foreliggende opfindelse at tilvejebringe et stabilt, flydende, kraftigt virkende, ikke-vandigt, ikke-ionisk rensemiddel indeholdende mindst en urins tof forbindelse som antiudfældende og stabiliserende middel og eventuelt et anionisk phosphatbuildersalt suspenderet i et ikke-ionisk 15 overfladeaktivt stof.It is an object of the present invention to provide a stable, liquid, powerful, non-aqueous, nonionic detergent containing at least one urine-like compound as anti-precipitating and stabilizing agent and optionally an anionic phosphate builder salt suspended in a nonionic surfactant.

Det er et andet formål med opfindelsen at tilvejebringe flydende stofbehandlingsmidler, som er suspensioner af uopløselige uorganiske partikler i en ikke-vandig væske, og som er lagerstabile, let hældelige og dispergerbare i koldt eller 20 varmt vand.It is another object of the invention to provide liquid fabric treating agents which are suspensions of insoluble inorganic particles in a non-aqueous liquid and which are storage stable, readily pourable and dispersible in cold or hot water.

Et andet formål med opfindelsen er at sammensætte kraftigt op-byggede, kraftigt virkende ikke-vandige flydende ikke-ioniske overfladeaktive tøjvaskemidler, som kan hældes ved alle temperaturer, og som kan dispergeres gentagne gange fra dispense-25 ringsaggregatet'i automatiske vaskemaskiner af europæisk type uden at tilsnavse eller tilstoppe dispenseringsaggregatet selv i vintermånederne.Another object of the invention is to assemble powerfully constructed, powerfully acting non-aqueous liquid nonionic surfactant detergents which can be poured at any temperature and which can be repeatedly dispersed from the dispensing assembly of European-type automatic washing machines without soiling or clogging the dispensing unit even during the winter months.

Et særligt formål med opfindelsen er at angive ikke-gelerende, stabile suspensioner af kraftigt virkende builderholdige ikke-30 vandige flydende, ikke-ioniske tøjvaskemidler, som indeholder en effektiv mængde af en urinstofforbindelse tilstrækkelig til at forøge flydespændingen af midlet for derved at forøge dets DK 168637 B1 9 stabilitet, dvs. forhindre udfældning af builderpartikler osv., fortrinsvis samtidigt med, at den plastiske viskositet (viskositet under forskydningsbetingelser) af midlet reduceres eller i det mindste ikke forøges.A particular object of the invention is to provide non-gelling, stable suspensions of strongly acting builder-containing non-aqueous liquid, nonionic laundry detergents which contain an effective amount of a urea compound sufficient to increase the yield stress of the agent thereby increasing its DK Stability, ie. prevent buildup of builder particles, etc., preferably at the same time as reducing or at least not increasing the plastic viscosity (viscosity under shear conditions).

5 Disse og andre formål med opfindelsen, som vil fremgå nærmere af følgende detaljerede beskrivelse af foretrukne udførelsesformer, angives generelt til fremstilling af et rensemiddel ved til det ikke-vandige flydende ikke-ioniske overfladeaktive stof at sætte en effektiv mængde af en urinstofforbindelse som 10 antiudfældende og stabiliserende middel tilstrækkelig til at hindre udfældning af de suspenderede partikler, hvor midlet indbefatter uorganiske eller organiske stofbehandlingsadditiver, f.eks. viskositetsforbedrende midler og et eller flere antigeleringsmidler, antiinkrustationsmidler, pH-regule-15 ringsmidler, blegemidler, blegeaktivatorer, antiskummemidler, optiske klaringsmidler, enzymer, midler til hindring af genaflejring af snavs, parfume og farvestoffer.These and other objects of the invention, which will become more apparent from the following detailed description of preferred embodiments, are generally set forth for the preparation of a detergent by adding to the non-aqueous liquid nonionic surfactant an effective amount of a urea compound as anti-precipitating agent. and stabilizing agent sufficient to prevent the precipitation of the suspended particles, wherein the agent includes inorganic or organic substance processing additives, e.g. viscosity enhancing agents and one or more anti-gelling agents, anti-incrustation agents, pH control agents, bleaching agents, bleach activators, anti-foaming agents, optical clarifiers, enzymes, agents for preventing re-deposition of dirt, perfume and dyes.

Den foreliggende opfindelse angår således et ikke-vandigt, kraftigt virkende, opbygget tøjvaskemiddel, som er hældeligt 20 ved høj og lav temperatur og ikke gelerer, når det blandes med koldt vand, hvilket tøjvaskemiddel er ejendommeligt ved, at det omfatter: mindst et flydende, ikke-ionisk, overfladeaktivt stof i en mængde fra 10 til 70 vægt%, mindst et uorganisk detergent-25 buildersalt suspenderet i det ikke-ioniske, overfladeaktive stof i en mængde fra 10 til 60 vægt%, et syreafsluttet, ikke-ionisk, Overfladeaktivt stof, som gelhindrende additiv, i en mængde fra 0 til 20 vægt%, mindst en alkylenglycol, som viskositetsregulerende og gelhindrende additiv, i en mængde fra 5 30 til 30 vægt%, og 0,2 til 2,0 vægt% af en urinstof forbindelse som antiudfældende og stabiliserende middel.Thus, the present invention relates to a non-aqueous, powerfully acting laundry detergent which is pourable at high and low temperature and does not gel when mixed with cold water, which laundry detergent is characterized in that it comprises: at least one liquid, nonionic surfactant in an amount of 10 to 70% by weight, at least one inorganic detergent builder salt suspended in the nonionic surfactant in an amount of 10 to 60% by weight, an acid-terminated, nonionic, surfactant substance, as a gel-inhibiting additive, in an amount from 0 to 20% by weight, at least one alkylene glycol, as a viscosity regulating and gel-inhibiting additive, in an amount of from 5 to 30% by weight, and 0.2 to 2.0% by weight of a urea compound as anti-precipitating and stabilizing agent.

Ifølge den foreliggende opfindelse bliver den fysiske stabilitet af suspensionen af den anioniske phosphatbuilderforbin-delse eller den anioniske builderforbindelse eller forbindel DK 168637 B1 10 ser og eventuelle andre suspenderede additiver, såsom blegemiddel osv., i den flydende ikke-ioniske overfladeaktive bærer væsentligt forbedret ved tilsætning af et antiudfældende og stabiliserende middel, som er urinstof.According to the present invention, the physical stability of the suspension of the anionic phosphate builder compound or the anionic builder compound or compound DK 168637 B110 and any other suspended additives such as bleach, etc., in the liquid nonionic surfactant carrier is greatly enhanced by addition. of an anti-precipitating and stabilizing agent which is urea.

5 Tilsætningen af meget små mængder af urinstoffet som antiudfældende og stabiliserende middel er tilstrækkelig til væsentligt at forbedre den fysiske stabilitet af rensemidlerne. Urinstoffet som antiudfældende middel forbedrer også væsentligt dispergerbarheden af midlerne i vand.The addition of very small amounts of the urea as an anti-precipitating and stabilizing agent is sufficient to significantly improve the physical stability of the detergents. The urea as an anti-precipitant also significantly improves the dispersibility of the agents in water.

10 I en udforelsesform ifølge opfindelsen indeholder midlerne som væsentlig bestanddel urinstof som et antiudfældende og stabiliserende additiv. Det antiudfældende og stabiliserende additiv kan omfatte en eller flere urinstofforbindelser.In one embodiment of the invention, the agents contain as essential ingredient urea as an anti-precipitating and stabilizing additive. The anti-precipitating and stabilizing additive may comprise one or more urea compounds.

Urinstofforbindelserne, der anvendes i midlerne ifølge opfin-15 delsen, har formlen R^I^NCNI^R^The urea compounds used in the compositions of the invention have the formula R

hvor mindst en af R-j_ til R4 er hydrogen og resten er alkyl, fortrinsvis -alkyl, aryl, fortrinsvis phenyl, hydroxyl 20 eller chlor, og X er 0 eller NH. Urinstoffet danner en tautomer, som har formlen HnNCNHOH og kaldes carbamid. Urinstof og “ t carbamidforbindelser og derivater, såsom methylurinstof, dime-thylurinstof, ethylurinstof, propylurinstof, butylurinstof, hydroxylurinstof og phenylurinstof, og salte af de foregående 25 er egnede til brug ifølge opfindelsen.wherein at least one of R 1 to R 4 is hydrogen and the balance is alkyl, preferably -alkyl, aryl, preferably phenyl, hydroxyl or chloro, and X is 0 or NH. The urea forms a tautomer which has the formula HnNCNHOH and is called carbamide. Urea and carbamide compounds and derivatives such as methylurea, dimethylurea, ethylurea, propylurea, butylurea, hydroxylurea and phenylurea, and salts of the foregoing are suitable for use in the invention.

Foruden virkningen som et fysisk stabiliseringsmiddel, har urinstofforbindelserne fordele frem for andre fysiske stabiliseringsmidler derved, at de er forenelige med den ikke-ioniske overfladeaktive komponent, og at de væsentligt forbedrer dis-30 pergerbarheden af rensemidlet i koldt vand.In addition to the effect of a physical stabilizer, the urea compounds have advantages over other physical stabilizers in that they are compatible with the nonionic surfactant component and substantially enhance the dispersibility of the detergent in cold water.

Selv om opfindelsen ikke er bundet til nogen særlig teori og måden, hvorpå urinstofforbindelserne eller carbamidforbindel- DK 168637 B1 11 serne virker til forhindring af udfældning af de suspenderede anioniske phosphatbuilderpartikler, antages det, at urinstof-forbindelserne eller carbamidforbindelserne reagerer med de anioniske phosphatbuildersalte og gør phosphatet mere forene-5 ligt med det ikke-ioniske overfladeaktive stof, forbedrer kontakten mellem phosphatet og det ikke-ioniske overfladeaktive stof og forøger befugteligheden af de dispergerede faste phos-phatpartiklers overflade med det ikke-ioniske overfladeaktive stof. Forbedringen i kontakten mellem phosphatet og det ikke-10 ioniske overfladeaktive stof og den forbedrede befugtelighed af de dispergerede phosphatpartikler med det ikke-ioniske overfladeaktive stof forøger stabiliteten af phosphatsuspen-sionen i det ikke-ioniske overfladeaktive middel og bevirker, at det suspenderede phosphat lettere forbliver i suspension.Although the invention is not tied to any particular theory and the manner in which the urea compounds or carbamide compounds act to prevent the precipitation of the suspended anionic phosphate builder particles, it is believed that the urea compounds or carbamide compounds react with the anionic phosphate compounds. the phosphate more compatible with the nonionic surfactant, improves contact between the phosphate and the nonionic surfactant and increases the wettability of the dispersed solid phosphate particles with the nonionic surfactant. The improvement in contact between the phosphate and the nonionic surfactant and the improved wettability of the dispersed phosphate particles with the nonionic surfactant increases the stability of the phosphate suspension in the nonionic surfactant and causes the suspended phosphate to remain more easily. in suspension.

15 Den forøgede fysiske stabilitet manifesterer sig ved en stigning i flyde spændingen af midlet sammenlignet med samme middel uden stabiliseringsmidlet. Som ovenfor beskrevet er det således, at jo højere flyde spændingen er, des højere er den tilsyneladende viskositet ved lav forskydningshastighed og des 20 bedre er den fysiske stabilitet.The increased physical stability is manifested by an increase in the flow tension of the agent compared to the same agent without the stabilizer. As described above, the higher the flow voltage, the higher the apparent viscosity at low shear rate and the better the physical stability.

Selv når urinstofforbindelsen sættes til midlet i små mængder, forbedrer den dispergerbarheden af suspensionen af buildersalt ved at virke til hindring af geldannelse af suspensionen af builder, når den kommer i kontakt med vand.Even when the urea compound is added to the agent in small amounts, it improves the dispersibility of the builder salt suspension by preventing gelling of the builder's suspension when in contact with water.

25 Urinstoffet forbedrer dispergerbarheden ved at hindre geldannelse af-suspensionen af buildersal tpartiklerne, når der sættes vand til midlet, f .eks. i dispenseringsaggregatet i en opvaskemaskine, og/eller når midlet sættes til vaskevandet.The urea improves dispersibility by preventing gelling of the suspension of the builder's salts when water is added to the agent, e.g. in the dispenser in a dishwasher, and / or when the agent is added to the washing water.

Der kræves kun meget små mængder af urinstof forbindelsen for 30 at opnå de betydelige forbedringer i fysisk stabilitet af rensemidlet og dispergerbarhed af midlet i koldt vand. Beregnet på den samlede vægt af det ikke-ioniske flydende overfladeaktive middel, er egnede mængder af urinstof f.eks. i interval- DK 168637 B1 12 let fra ca. 0,1% til ca. 5%, fortrinsvis fra ca. 0,2% til ca. 2,0%, og mere foretrukket ca. 0,5 - 1,5%.Only very small amounts of the urea compound are required to achieve the significant improvements in the physical stability of the detergent and dispersibility of the agent in cold water. Calculated on the total weight of the nonionic liquid surfactant, suitable amounts of urea are e.g. in range DK 168637 B1 12 easily from approx. 0.1% to approx. 5%, preferably from ca. 0.2% to approx. 2.0%, and more preferably approx. 0.5 - 1.5%.

Urinstofforbindelserne er effektive i deres fysiske stabiliserende virkning, men til præparatet kan sættes andre kendte 5 fysiske stabiliseringsmidler, som f .eks. en sur organisk phos-phorforbindelse der har en sur POH-gruppe, såsom partielester af phosphorsyre og en alkanol og/eller et aluminiumsalt af en fedtsyre.The urea compounds are effective in their physical stabilizing effect, but other known physical stabilizers can be added to the composition, such as e.g. an acidic organic phosphorus compound having an acidic POH group, such as the partial ester of phosphoric acid and an alkanol and / or an aluminum salt of a fatty acid.

Ikke-ionisk overfladeaktiv detergent.Nonionic surfactant detergent.

10 De ikke-ioniske syntetiske organiske detergenter, der anvendes til opfindelsen, kan være ethvert af mange, forskellige kendte forbindelser.The nonionic synthetic organic detergents used in the invention may be any of many, various known compounds.

Som det er velkendt, er de ikke-ioniske syntetiske organiske detergenter karakteriseret ved tilstedeværelse af en organisk 15 hydrofob gruppe og en organisk hydrofil gruppe og fremstilles typisk ved kondensation af en organisk alifatisk eller alkyla-romatisk hydrofob forbindelse med ethylenoxid (hydrofil af karakter) . Praktisk taget enhver hydrofob forbindelse, der har en carboxy-, hydroxy-, amido- eller aminogruppe med et frit 20 hydrogen bundet til nitrogenet, kan kondenseres med ethylenoxid eller med polyhydratiseringsproduktet deraf, polyethylen-glycol til dannelse af en ikke-ionisk detergent. Længden af den hydrofile kæde eller polyoxyethylenkæden kan let indstilles til at opnå den ønskede balance mellem de hydrofobe og hy-25 drofile -grupper: Typiske egnede ikke-ioniske overfladeaktive stoffer er de, der er beskrevet i US-patenter nr. 4.316.812 og 3.630.929.As is well known, the nonionic synthetic organic detergents are characterized by the presence of an organic hydrophobic group and an organic hydrophilic group and are typically prepared by condensation of an organic aliphatic or alkylaromatic hydrophobic compound with ethylene oxide (hydrophilic in nature). Practically any hydrophobic compound having a carboxy, hydroxy, amido or amino group with a free hydrogen bonded to the nitrogen can be condensed with ethylene oxide or with its polyhydration product, polyethylene glycol to form a nonionic detergent. The length of the hydrophilic or polyoxyethylene chain can be readily adjusted to achieve the desired balance between the hydrophobic and hydrophilic groups: Typical suitable nonionic surfactants are those disclosed in U.S. Patent Nos. 4,316,812 and 3630929.

I reglen er de ikke-ioniske detergenter poly-lavere alkoxyle-rede lipofiler, hvori den ønskede hydrofile-lipofile balance 30 opnås ved tilføjelse af en hydrofil-poly-lavere alkoxygruppe til en lipofil molekyldel. En foretrukken klasse af det anvendte ikke-ioniske detergent er den poly-lavere alkoxylerede DK 168637 B1 13 højere alkanol, hvori alkanolen har 9-18 carbonatomer, og hvori antallet af mol af lavere-alkylenoxid (på 2-3 carbona-tomer) er fra 3 til 12. Af disse materialer foretrækkes det at anvende de, hvori den højere alkanol er en højere fedtalkohol 5 med 9-11 eller 12 - 15 carbonatomer, og som indeholder fra 5 til 8 eller 5 til 9 lavere-alkoxygrupper pr. mol. Fortrinsvis er det lavere alkoxy ethoxy, men i nogle tilfælde kan det hensigtsmæssigt være blandet med propoxy, idet sidstnævnte, hvis det er til stede, ofte er en mindre mængde (mindre end 50%).As a rule, the nonionic detergents are poly-lower alkoxylated lipophiles wherein the desired hydrophilic-lipophilic balance 30 is obtained by adding a hydrophilic-poly-lower alkoxy group to a lipophilic moiety. A preferred class of the nonionic detergent used is the poly lower alkoxylated higher alkanol wherein the alkanol has 9-18 carbon atoms and wherein the number of moles of lower alkylene oxide (of 2-3 carbon atoms) is From these materials it is preferred to use those in which the higher alkanol is a higher fatty alcohol 5 having 9-11 or 12-15 carbon atoms and containing from 5 to 8 or 5 to 9 lower alkoxy groups per liter. moth. Preferably, it is lower alkoxy ethoxy, but in some cases it may conveniently be mixed with propoxy, the latter, if present, often being a minor amount (less than 50%).

10 Eksempler på sådanne forbindelser er de, hvori alkanolen har 12 - 15 carbonatomer, og som indeholder ca. 7 ethylenoxidgrup-per pr. mol, f.eks. "Neodol 25-7" og "Neodol 23-6,5", hvilket produkter fremstilles af Shell Chemical-Company, Inc.. Førstnævnte er et kondensationsprodukt af en blanding af højere 15 fedtalkoholer med et gennemsnit på ca. 12 - 15 carbonatomer, med ca. 7 mol ethylenoxid og sidstnævnte er en tilsvarende blanding, hvori carbonatomindholdet i den højere fedtalkohol er 12 - 13 og antallet af ethylenoxidgrupper er i gennemsnit ca. 6,5. De høj ere alkoholer er primære alkanoler.Examples of such compounds are those in which the alkanol has 12 to 15 carbon atoms and contains about 7 ethylene oxide groups per moles, e.g. "Neodol 25-7" and "Neodol 23-6.5" which are manufactured by Shell Chemical-Company, Inc. The former is a condensation product of a mixture of higher 15 fatty alcohols with an average of approx. 12 to 15 carbon atoms, with approx. 7 moles of ethylene oxide and the latter is a similar mixture in which the carbon atom content of the higher fatty alcohol is 12-13 and the number of ethylene oxide groups is on average approx. 6.5. The higher alcohols are primary alkanols.

20 Andre eksempler på sådanne detergenter indbefatter Tergitol® 15-S-7 og Tergitol® 15-S-9, der begge er lineære sekundære alkoholethoxylater fremstillet af Union Carbide Corp.. Førstnævnte er et blandet ethoxyleringsprodukt af en lineær sekundær alkanol med 11 - 15 carbonatomer med 7 mol ethylenoxid og 25 sidstnævnte er et lignende produkt, men med 9 mol ethylenoxid reageret.Other examples of such detergents include Tergitol® 15-S-7 and Tergitol® 15-S-9, both of which are linear secondary alcohol ethoxylates manufactured by Union Carbide Corp. The former is a mixed ethoxylation product of a linear secondary alkanol having 11-15 carbon atoms with 7 moles of ethylene oxide and the latter are a similar product, but reacted with 9 moles of ethylene oxide.

Nyttig i det foreliggende middel som en komponent af det ikke-ioniske detergent er også 'højmolekylære ikke-ioniske stoffer, såsom "Neodol 45-11", som er lignende ethylenoxidkonden-30 sationsprodukter af højere fedtalkoholer, hvor den højere fedtalkohol har 14 - 15 carbonatomer og antallet af ethylenoxidgrupper pr. mol er ca. 11. Disse produkter fremstilles også af Shell Chemical Company.Also useful in the present invention as a component of the nonionic detergent are 'high molecular weight nonionic substances such as "Neodol 45-11" which are similar ethylene oxide condensation products of higher fatty alcohols, wherein the higher fatty alcohol has 14-15 carbon atoms and the number of ethylene oxide groups per mole is approx. 11. These products are also manufactured by Shell Chemical Company.

Andre nyttige ikke-ioniske stoffer repræsenteres af de industrielt velkendte ikke-ioniske stoffer, der forhandles under varemærket Plurafac®. Plurafac® er reaktionsproduktet af en højere lineær alkohol og en blanding af ethylen og propyleno-5 xider, indeholdende en blandet kæde af ethylenoxid og propyl-enoxid, afsluttet med en hydroxylgruppe. Eksempler indbefatter produkter, som er (A) C13-C15-fedtalkohol kondenseret med 6 mol ethylenoxid og 3 mol propylenoxid, (B) C13-C15-fedtalkohol kondenseret med 7 mol propylenoxid og 4 mol ethylenoxid, (C) 10 C13-C15-fedt alkohol kondenseret med 5 mol propylenoxid og 10 mol ethylenoxid, og (D) et produkt som er en l:l-blanding af produkterne (B) og (C).Other useful non-ionic substances are represented by the industrially well-known non-ionic substances sold under the Plurafac® trademark. Plurafac® is the reaction product of a higher linear alcohol and a mixture of ethylene and propylene oxides containing a mixed chain of ethylene oxide and propylene oxide, terminated with a hydroxyl group. Examples include products which are (A) C13-C15 fatty alcohol condensed with 6 moles of ethylene oxide and 3 moles of propylene oxide, (B) C13-C15 fatty alcohol condensed with 7 moles of propylene oxide and 4 moles of ethylene oxide, (C) 10 C13-C15. fatty alcohol condensed with 5 moles of propylene oxide and 10 moles of ethylene oxide, and (D) a product which is a 1: 1 mixture of products (B) and (C).

En anden gruppe flydende ikke-ioniske stoffer findes i handelen fra Shell Chemical Company, In'c. under varemærket Dobanol®: 15 Dobanol® 91-5 er en ethoxyleret Cg-C11-fedtalkohol med i gennemsnit 5 mol ethylenoxid og Dobanol® 25-7 er en ethoxyleret Ci2 “ Cis - fedt alkohol med i gennemsnit 7 mol ethylenoxid pr. mol fedtalkohol.Another group of liquid non-ionic substances is found in the trade of Shell Chemical Company, In'c. under the trade mark Dobanol®: 15 Dobanol® 91-5 is an ethoxylated Cg-C11 fatty alcohol with an average of 5 moles of ethylene oxide and Dobanol® 25-7 is an ethoxylated C12- Cis-fatty alcohol with an average of 7 moles of ethylene oxide. moles of fatty alcohol.

For at opnå den bedste balance mellem hydrofile og lipofile 20 molekyldele i de foretrukne poly-lavere alkoxylerede højere alkanoler, vil antallet af lavere alkoxygrupper i reglen være fra 40% til 100% af antallet af carbonatomer i den højere alkohol, fortrinsvis 40 - 60% deraf, og det ikke-ioniske detergent vil fortrinsvis indeholde mindst 50% af en sådan fore-25 trukken poly-lavere alkoxy højere alkanol. Mere højmolekylære alkanoler og forskellige andre normalt faste ikke-ioniske detergenter og overfladeaktive midler kan bidrage til gelering af det flydende detergent og vil derfor fortrinsvis blive udeladt eller begrænset i mængde i de foreliggende midler, omend 30 mindre mængder deraf kan anvendes på grund af deres rensende egenskaber osv.. Med hensyn til både foretrukne og mindre foretrukne ikke-ioniske detergenter er alkylgrupperne, som findes deri, i almindelighed lineære omend forgrening kan tolereres, såsom ved et carbonatom ved siden af eller to carbonatom-35 er fjernet fra det endestillede carbonatom i den lige kæde og DK 168637 B1 15 bort fra ethoxykæden, hvis et sådant forgrenet alkyl ikke har en længde på mere end 3 carbonatomer. Normalt vil mængden af carbonatomer i en sådan forgrenet konfiguration være mindre og sjældent overstige 20% af det samlede carbonatomindhold i al-5 kylet. Selv om lineære alkyler, der er endestillet forbundet med ethyl enoxidkæderne, meget foretrækkes og anses for at resultere i den bedste kombination af renseevne, bionedbrydelig-hed og ikke-gelerende egenskaber, kan midterstillet eller sekundær forbinding til ethylenoxidet i kæden forekomme. Det 10 er i reglen kun i en mindre mængde af sådanne alkyler, i almindelighed mindre end 20%, men som i tilfældet med de nævnte Tergitol®-er kan det være større. Når propylenoxid findes i den lavere-alkylenoxidkæde, vil det også i reglen være mindre end 20% deraf og fortrinsvis mindre end-10% deraf.In order to achieve the best balance between hydrophilic and lipophilic 20 moieties in the preferred poly-lower alkoxylated higher alkanols, the number of lower alkoxy groups will generally be from 40% to 100% of the number of carbon atoms in the higher alcohol, preferably 40-60%. thereof, and the nonionic detergent will preferably contain at least 50% of such preferred poly lower alkoxy higher alkanol. More high molecular weight alkanols and various other normally solid nonionic detergents and surfactants may contribute to the gelation of the liquid detergent and will therefore preferably be omitted or limited in amount in the present agents, although 30 smaller amounts thereof may be used due to their purification. properties, etc. With respect to both preferred and less preferred nonionic detergents, the alkyl groups contained therein are generally linear although branching can be tolerated, such as at a carbon atom adjacent to or two carbon atoms removed from the terminated carbon atom. the straight chain and DK168637 B1 15 away from the ethoxy chain if such branched alkyl does not have a length of more than 3 carbon atoms. Usually, the amount of carbon atoms in such a branched configuration will be less and rarely exceed 20% of the total carbon atom content of the alkyl. Although linear alkyls terminally linked to the ethylene oxide chains are highly preferred and considered to result in the best combination of purity, biodegradability and non-gelling properties, intermediate or secondary linkage to the ethylene oxide in the chain may occur. It is usually only in a smaller amount of such alkyls, generally less than 20%, but as in the case of the Tergitol®s mentioned, it may be larger. When propylene oxide is found in the lower alkylene oxide chain, it will also generally be less than 20% thereof and preferably less than 10% thereof.

15 Når der anvendes større mængder af alkanoler som ikke er alko-xyleret i enden, propylenoxidholdige poly-lavere alkoxylerede alkanoler og mindre hydrofilt-lipofilt afbalanceret ikke-io-nisk detergent end nævnt ovenfor, og når der anvendes andre ikke-ioniske detergenter i stedet for de heri foretrukne ikke-20 ioniske stoffer, kan det fremkommende produkt muligvis ikke have så god renseevne, stabilitet, viskositet og ikke-gele-rende egenskaber, som de foretrukne midler, men anvendelsen af de viskositetsregulerende og gelregulerende forbindelser ifølge opfindelsen kan også forbedre egenskaberne af detergenter 25 baseret på sådanne ikke-ioniske stoffer. I nogle tilfælde, som når der anvendes en højmolekylær poly-lavere alkoxyleret højere alkanol, ofte på grund af dens rensevirkning, vil mængden deraf være reguleret eller begrænset i overensstemmelse med resultaterne af rutineforsøg, for at opnå den ønskede rense-30 evne og stadig have et ikke-gelerende produkt med ønsket viskositet. Det har også vist sig, at det kun sjældent er nødvendigt at anvende de højmolekylære ikke-ioniske stoffer på grund af deres renseegenskaber, idet de foretrukne ikke-ioniske stoffer beskrevet i den foreliggende ansøgning er udmærkede 35 detergenter og desuden muliggør at opnå den ønskede viskositet i det flydende rensemiddel uden gelering ved lave temperatu- DK 168637 B1 16 rer.When larger amounts of non-alkoxylated non-alkoxylated alkanols are used, propylene oxide-containing poly lower alkoxylated alkanols and less hydrophilic-lipophilic balanced non-ionic detergent than mentioned above and when other non-ionic detergents are used instead for the preferred non-ionic substances herein, the resulting product may not have as good purity, stability, viscosity and non-gelling properties as the preferred agents, but the use of the viscosity-regulating and gel-regulating compounds of the invention may also improve the properties of detergents 25 based on such nonionic substances. In some cases, when using a high molecular weight poly-lower alkoxylated higher alkanol, often because of its purification effect, the amount thereof will be controlled or limited in accordance with the results of routine experiments to achieve the desired purity and still have a non-gelling product of desired viscosity. It has also been found that the high molecular weight non-ionic substances are rarely used due to their cleaning properties, the preferred non-ionic substances described in the present application being excellent 35 detergents and additionally enabling the desired viscosity to be achieved. in the liquid detergent without gelling at low temperatures.

En anden nyttig gruppe ikke-ioniske overfladeaktive stoffer er "Surfactant T"-rækken af ikke-ioniske stoffer, der fås fra British Petroleum. "Surfactant T" ikke-ioniske stoffer fås ved 5 ethoxylering af sekundære C13-fedtalkoholer med en snæver ethylenoxidfordeling. "Surfactant T5" har i gennemsnit 5 mol ethylenoxid; "Surfactant T7" i gennemsnit 7 mol ethylenoxid; "Surfactant T9" i gennemsnit 9 mol ethylenoxid og "Surfactant T12" i gennemsnit 12 mol ethylenoxid pr. mol sekundær C13fedt-10 alkohol.Another useful group of non-ionic surfactants is the "Surfactant T" series of non-ionic substances available from British Petroleum. "Surfactant T" nonionic substances are obtained by ethoxylation of secondary C13 fatty alcohols with a narrow ethylene oxide distribution. "Surfactant T5" has on average 5 moles of ethylene oxide; "Surfactant T7" averages 7 moles of ethylene oxide; "Surfactant T9" averaged 9 moles of ethylene oxide and "Surfactant T12" averaged 12 moles of ethylene oxide per mole of secondary C13 fat-10 alcohol.

I midlerne ifølge opfindelsen indbefatter foretrukne ikke--ioniske overfladeaktive stoffer de C-^-Cig-sekundære fedtalkoholer med forholdsvis snævert indhold af ethylenoxid i intervallet fra ca. 7 til 9 mol, og Cg-C1;L-fedtalkoholer ethoxyle-15 ret med ca. 5 - 6 mol ethylenoxid.In the compositions of the invention, preferred nonionic surfactants include the C C - Cigig secondary fatty alcohols having relatively narrow ethylene oxide content in the range of from 7 to 9 moles, and Cg-C1; L-fatty alcohols ethoxylated with ca. 5 - 6 moles of ethylene oxide.

Blandinger af to eller flere af de flydende ikke-ioniske overfladeaktive stoffer kan anvendes og i nogle tilfælde kan der opnås fordele ved at anvende sådanne blandinger.Mixtures of two or more of the liquid nonionic surfactants can be used and in some cases benefits can be obtained from using such mixtures.

Svreafsluttet ikke-ionisk overfladeaktivt stof.Heavy-duty non-ionic surfactant.

20 Viskositeten og gelegenskaberne af de flydende rensemidler kan forbedres ved i midlet at inkludere en effektiv mængde af et syreafsluttet flydende ikke-ionisk overfladeaktivt stof. De syreafsluttede ikke-ioniske overfladeaktive stoffer består af et ikke-ionisk overfladeaktivt stof som er blevet modificeret 25 til omdannelse af en fri hydroxyl gruppe deri til en molekyldel der har en fri carboxyl gruppe, såsom en ester eller en par-tialester af et ikke-ionisk overfladeaktivt stof, og en poly-carboxylsyre eller et anhydrid.The viscosity and gel properties of the liquid detergents can be improved by including in the agent an effective amount of an acid-terminated liquid nonionic surfactant. The acid terminated nonionic surfactants consist of a nonionic surfactant which has been modified to convert a free hydroxyl group therein into a molecule having a free carboxyl group such as an ester or a partial ester of a non-ionic surfactant. ionic surfactant, and a polycarboxylic acid or anhydride.

Som beskrevet i den samtidige ansøgning nr. 597.948, hvis ind-30 hold inkorporeres heri gennem denne henvisning, virker de ikke-ioniske overfladeaktive stoffer, som er modificeret med DK 168637 B1 17 en fri carboxylgruppe, og som bredt kan karakteriseres som po-lyethercarboxylsyrer, til at nedsætte den temperatur, ved hvilken det flydende ikke-ioniske stof danner en gel med vand.As described in copending application No. 597,948, the contents of which are incorporated herein by reference, the nonionic surfactants modified with DK 168637 B1 17 act as a free carboxyl group and which can be broadly characterized as polyether carboxylic acids , to reduce the temperature at which the liquid non-ionic substance forms a gel with water.

Tilsætningen af de syreafsluttede ikke-ioniske overfladeaktive 5 stoffer til det flydende ikke-ioniske overfladeaktive middel hjælper til dispenserbarheden af midlet, dvs. hældeligheden, og nedsætter den temperatur, ved hvilken de flydende ikke-ioniske overfladeaktive stoffer danner en gel i vand uden et fald i deres stabilitet mod udfældning. De syreafsluttede 10 ikke-ioniske overfladeaktive stoffer reagerer i vaskemaskinens vand med alkaliniteten af den dispergerede buildersaltfase i rensemidlet og virker som et effektivt anionisk overfladeaktivt stof.The addition of the acid terminated nonionic surfactants to the liquid nonionic surfactant aids in the dispensability of the agent, i.e. the pourability, and decreases the temperature at which the liquid nonionic surfactants form a gel in water without a decrease in their stability to precipitation. The acid-terminated 10 nonionic surfactants react in the washing machine's water with the alkalinity of the dispersed builder's salt phase in the detergent and act as an effective anionic surfactant.

Konkrete eksempler indbefatter halvesterne af produkt (A) med 15 ravsyreanhydrid, esteren eller halvesteren af Dobanol® 25-7 med ravsyreanhydrid og esteren eller halvesteren af Dobanol® 91-5 med ravsyreanhydrid.

Acid-terminated Dobanol® 91-5. 1000 g of Dobanol® 91-5 non-ionic surfactant, which is the ethoxylation product of a C9-Cii alkanol and has approx. 5 ethylene oxide units per molecule 10 alkanol, mixed with 265 g of succinic anhydride and 0.1 g of pyridine catalyst and heated to 260 ° C for 2 hours, cooled and filtered to remove unreacted succinic material. Infrared analysis shows that substantially all the free hydroxyl groups in the surfactant have reacted.

15 Andre forestringskatalysatorer, såsom et alkalimetalalkoxid (f.eks. natriummethoxid) kan anvendes i stedet for eller i blanding med pyridin.Other esterification catalysts such as an alkali metal alkoxide (e.g., sodium methoxide) may be used in place of or in admixture with pyridine.

De sure polyetherforbindelser, dvs. de syreafsluttede ikke-ioniske overfladeaktive stoffer, tilsættes fortrinsvis opløst 20 i det ikke-ioniske overfladeaktive stof.The acidic polyether compounds, i.e. the acid-terminated nonionic surfactants are preferably added dissolved in the nonionic surfactant.

Buildersalte.Builder.

Det flydende ikke-vandige ikke-ioniske overfladeaktive stof anvendt i midlerne ifølge opfindelsen har dispergeret og suspenderet deri fine partikler af uorganiske og/eller uorganiske 25 rensemiddelbuildersalte.The liquid non-aqueous nonionic surfactant used in the compositions of the invention has dispersed and suspended therein fine particles of inorganic and / or inorganic detergent builder salts.

Rensemidlerne ifølge opfindelsen indbefatter vandopløselige og/eller vanduopløselige rensemiddelbuildersalte. Vandopløselige uorganiske alkaliske buildersalte, der kan anvendes alene sammen med detergentforbindelsen eller i blanding med andre 30 buildere, er alkalimetalcarbonater,- bicarbonater, borater, phosphater, polyphosphater og silikater. (Ammoniumsalte eller substituerede ammoniumsalte kan også anvendes) . Særlige eksem- '1 19 DK 168637 B1 pier på sådanne salte er natriumtripolyphosphat, natriumcarbo-nat, natriumtetraborat, natriumpyrophosphat, kaliumpyrophos-phat, natriumbicarbonat, kaliumtripolyphosphat, natriumhexame-taphosphat, natriumsesquicarbonat, natriummono- og dior-5 thophosphat og kaliuinbicarbonat. Natriumtripolyphosphat (TPP) foretrækkes især.The detergents of the invention include water-soluble and / or water-insoluble detergent builder salts. Water-soluble inorganic alkaline builder salts which can be used alone with the detergent compound or in admixture with other builders are alkali metal carbonates, bicarbonates, borates, phosphates, polyphosphates and silicates. (Ammonium salts or substituted ammonium salts may also be used). Particular examples of such salts are sodium tripolyphosphate, sodium carbonate, sodium tetraborate, sodium pyrophosphate, potassium pyrophosphate, sodium bicarbonate, potassium tripolyphosphate, sodium hexame-taphosphate and sodium phosphate phosphate, sodium sesquicarbonate, sodium sesquicarbonate, sodium sesquicarbonate Sodium tripolyphosphate (TPP) is particularly preferred.

Da midlerne ifølge opfindelsen i almindelighed er højt koncentrerede og derfor kan anvendes i forholdsvis lave doser, er det ønskeligt at supplere eventuel phosphatbuilder (såsom na-10 triumtripolyphosphat) med en hjælpebuilder, såsom en polylave-re carboxylsyre eller en polymer carboxylsyre, der har høj calciumbindingsevne, for at hindre inkrustation, som ellers kunne forekomme på grund af dannelse af- et. uopløseligt calci-umphosphat.Since the agents of the invention are generally highly concentrated and therefore can be used in relatively low doses, it is desirable to supplement any phosphate builder (such as sodium tripolyphosphate) with an auxiliary builder such as a polylated carboxylic acid or a high carboxylic acid polymer. calcium binding capacity, to prevent encrustation which might otherwise occur due to formation thereof. insoluble calcium phosphate.

15 En egnet lavere polycarboxylsyre omfatter alkalimetalsaltene af lavere polycarboxylsyrer, fortrinsvis natrium- og kaliumsaltene. Egnede lavere polycarboxylsyrer har to til fire carboxyl syregrupper. De foretrukne natrium- og kalium-lavere po-lycarboxylsyresalte er citronsyre- og vinsyresaltene.A suitable lower polycarboxylic acid comprises the alkali metal salts of lower polycarboxylic acids, preferably the sodium and potassium salts. Suitable lower polycarboxylic acids have two to four carboxylic acid groups. The preferred sodium and potassium lower polycarboxylic acid salts are the citric and tartaric acid salts.

20 Natriumcitronsyresaltene er de mest foretrukne, især trina-triumcitratet. Mononatrium- og dinatriumcitratet kan også anvendes. Mononatrium- og dinatriumvinsyresaltene kan også anvendes. Alkalimetal-lavere polycarboxyl syresal te er særligt gode buildersalte. På grund af deres store calcium- og magni-25 umbindingsevne hindrer de inkrustation, som ellers kunne forårsages ved dannelse af uopløselige calcium- og magniumsalte.The sodium citric acid salts are the most preferred, especially the trisodium citrate. The monosodium and disodium citrate can also be used. The monosodium and disodium tartaric acid salts may also be used. Alkali metal-lower polycarboxylic acid salt teas are particularly good builder salts. Because of their high calcium and magnesium binding capacity, they inhibit encrustation which could otherwise be caused by the formation of insoluble calcium and magnesium salts.

Andre organiske buildere er polymerer og copolymerer af poly-acrylsyre og polymaleinsyreanhydrid og alkalimetalsaltene deraf. Mere specielt kan sådanne buildersalte bestå af en copo-30 lymer, som er reaktionsproduktet af ca. lige mol methacrylsyre og maleinsyreanhydrid, der er blevet· fuldstændigt neutraliseret til dannelse af natriumsaltet deraf. Builderen findes i handelen under handelsnavnet "Sokalan CP5". Denne builder DK 168637 B1 20 tjener til at hindre inkrustation, selv når den anvendes i små mængder.Other organic builders are polymers and copolymers of polyacrylic acid and polymaleic anhydride and the alkali metal salts thereof. More particularly, such builder salts may consist of a copolymer, which is the reaction product of ca. equal moles of methacrylic acid and maleic anhydride, which have been completely neutralized to form the sodium salt thereof. The builder is available in the trade under the trade name "Sokalan CP5". This builder DK 168637 B1 20 serves to prevent encrustation even when used in small quantities.

Eksempler på organiske alkaliske kompleksbindende buildersal-te, der kan anvendes sammen med rensemiddelbuildersaltene 5 eller i blanding med andre organiske og uorganiske buildere, er alkalimetal, ammonium eller substitueret ammonium aminopo-lycarboxylater, f.eks. natrium- og kaliumethylendiamintetra-acetat (EDTA), natrium- og kaliumnitrilotriacetater (NTA) og triethanolammonium-N- (2-hydroxy et hyl) nitrilodiacetat .Blandede 10 salte af disse aminopolycarboxylater er også egnede.Examples of organic alkaline complex-binding builder salts that can be used with the scavenger builder salts 5 or in admixture with other organic and inorganic builders are alkali metal, ammonium or substituted ammonium aminopolycarboxylates, e.g. sodium and potassium ethylenediaminetetraacetate (EDTA), sodium and potassium nitrilotriacetates (NTA) and triethanolammonium N- (2-hydroxy etyl) nitrilodiacetate. Mixed 10 salts of these aminopolycarboxylates are also suitable.

Andre egnede buildere af den organiske type indbefatter car-boxymethylsuccinater, tartronater og glycolater. Af særlig værdi er polyacetalcarboxylaterne. Polyacetalcarboxylaterne og deres anvendelse i rensemidler er beskrevet i de amerikanske 15 patentskrifter nr. 4.144.226, 4.315.092 og 4.146.495.Other suitable builders of the organic type include carboxymethyl succinates, tartronates and glycolates. Of particular value are the polyacetal carboxylates. The polyacetal carboxylates and their use in detergents are described in U.S. Patents Nos. 4,144,226, 4,315,092, and 4,146,495.

Alkalimetalsilicaterne er nyttige buildersalte, der også virker til indstilling eller regulering af pH-værdien og til at gøre midlet antikorroderende overfor vaskemaskinens dele. Natriumsilikater med Na20/Si02-forhold fra 1,6/1 til 1/3,2, især 20 ca. 1/2 til 1/2,8 foretrækkes. Kaliumsilikater med samme forhold kan også anvendes.The alkali metal silicates are useful builder salts which also act to adjust or adjust the pH and to make the agent anticorrosive to the parts of the washing machine. Sodium silicates with Na 2 O / SiO 2 ratios from 1.6 / 1 to 1 / 3.2, especially about 20%. 1/2 to 1 / 2.8 is preferred. Potassium silicates with the same ratio can also be used.

Andre typiske' egnede buildere indbefatter f.eks. de, der er beskrevet i de amerikanske patenter nr. 4.316.812, 4.264.466 og 3.630.929.

Tilsætning til rensemidlet af en effektiv mængde af viskosi-tetsregulerende og gelhindrende midler for det ikke-ioniske overfladeaktive stof forbedrer lageregenskaberne af midlet. De DK 168637 B1 22 viskositetsregulerende og gelhindrende midler virker til nedsættelse af den temperatur, ved hvilken det ikke-ioniske overfladeaktive stof vil danne en gel, når det sættes til vand. Disse viskositetsregulerende og gelhindrende midler kan f .eks.Addition to the detergent of an effective amount of viscosity regulating and gel inhibiting agents for the nonionic surfactant improves the storage properties of the agent. The viscosity regulating and gel preventing agents act to reduce the temperature at which the nonionic surfactant will form a gel when added to water. These viscosity regulating and gel inhibiting agents can e.g.

Indholdet i midlet af den lavmolekylære lavere alkylenglycol-monoalkylether nedsætter midlets viskositet, således at det er lettere hældeligt, forbedrer stabiliteten mod udfældning og forbedre dispergerbarheden af midlet ved tilsætning til varmt 10 eller koldt vand.The content of the low molecular weight lower alkylene glycol monoalkyl ether agent lowers the viscosity of the agent so that it is more easily pourable, improves the stability to precipitation and improves the dispersibility of the agent when added to hot or cold water.

Midlerne ifølge opfindelsen har forbedret viskositet og stabilitet og forbliver stabile og hældelige ved temperaturer så lave som ca. 5°C og lavere.The compositions of the invention have improved viscosity and stability and remain stable and pourable at temperatures as low as approx. 5 ° C and lower.

Foruden at virke som antiudfældende og stabiliserende middel 15 virker urinstofforbindelserne til forbedring af dispergerbarheden af suspensionen af phosphatbuilderpartiklerne ved at hæmme geldannelse af de suspenderede partikler, når koldt vand sættes til midlet i dispenseringsaggregatet og/eller når midlet sættes til vand.In addition to acting as anti-precipitating and stabilizing agent 15, the urea compounds act to improve the dispersibility of the suspension of the phosphate builder particles by inhibiting the gelling of the suspended particles when cold water is added to the agent in the dispensing assembly and / or when the agent is added to water.

20 I en udførelsesform ifølge opfindelsen kan et supplerende stabiliserende middel, som er en alkanolester af phosphorsyre eller et aluminiumsalt af en højere fedtsyre, sættes til sammensætningen .In an embodiment of the invention, a supplemental stabilizing agent, which is an alkanol ester of phosphoric acid or an aluminum salt of a higher fatty acid, can be added to the composition.

Forbedringer i stabilitet af midlet kan opnås ved at inkorpo-25 rere en lille effektiv mængde af en sur organisk phosphorfor-bindelse, der har en sur ÉOH-gruppe, såsom en partialester af phosphorsyre og en alkanol.Improvements in stability of the agent can be achieved by incorporating a small effective amount of an acidic organic phosphorus compound having an acidic EOH group such as a partial ester of phosphoric acid and an alkanol.

Den sure organiske phosphorforbindelse, der har en sur POH-gruppe, kan forøge stabiliteten -af suspensionen af buil-30 dere i det ikke-vandige flydende ikke-ioniske overfladeaktive stof.The acidic organic phosphorus compound having an acidic POH group can enhance the stability of the suspension of buildup in the non-aqueous liquid nonionic surfactant.

DK 168637 B1 24DK 168637 B1 24

Den sure organiske phosphorforbindelse kan f .eks. være en par-tialester af phosphorsyre og en alkohol, såsom en alkanol, der har en lipofil karakter og har f .eks. mere end 5 carbonatomer, f.eks. 8-20 carbonatomer.The acidic organic phosphorus compound can e.g. be a partial ester of phosphoric acid and an alcohol such as an alkanol having a lipophilic character and having e.g. more than 5 carbon atoms, e.g. 8-20 carbon atoms.

5 Et særligt eksempel er en partialester af phosphorsyre og en <216-018-alkanol (Empiphos® 5632 fra Marchon) . Den udgøres af ca. 35% monoester og 65% diester.A particular example is a partial ester of phosphoric acid and an <216-018 alkanol (Empiphos® 5632 from Marchon). It consists of approx. 35% monoester and 65% diester.

Tilsætning af ganske små mængder af den sure organiske phosphorforbindelse gør suspensionen stabil mod udfældning ved 10 henstand, men den forbliver hældelig samtidigt med, at dens plastiske viskositet i almindelighed aftager ved lav koncentration af stabiliseringsmiddel, f.eks.-under ca. 1%.Adding very small amounts of the acidic organic phosphorus compound makes the suspension stable against precipitation upon standing, but it remains pourable while its plastic viscosity generally decreases at a low concentration of stabilizing agent, e.g. 1%.

Forbedringer i stabiliteten og antiudfældningsegenskaberne af midlet kan også opnås ved tilsætning af en lille effektiv 15 mængde af et aluminiumsalt af en højere fedtsyre.Improvements in the stability and anti-precipitation properties of the agent can also be achieved by the addition of a small effective amount of an aluminum salt of a higher fatty acid.

De stabiliserende aluminiumsalte er genstand for den samtidige ansøgning nr. 725.455.The stabilizing aluminum salts are the subject of co-application No. 725,455.

Den foretrukne højere alifatiske fedtsyre vil have fra ca.8 til ca. 22 carbonatomer, mere foretrukket fra ca. 10 til 20 20 carbonatomer, og især fra ca. 12 til 18 carbonatomer. Det alifatiske radikal kan være mættet eller umættet og kan være li-gekædet eller forgrenet. Som i tilfældet med de ikke-ioniske overfladeaktive stoffer kan der også anvendes blandinger af fedtsyrer, såsom de der er afledt af naturlige kilder, såsom 25 talgfedtsyre, kokosfedtsyre osv..The preferred higher aliphatic fatty acid will have from about 8 to about 22 carbon atoms, more preferably from about 10 to 20 carbon atoms, and especially from about 12 to 18 carbon atoms. The aliphatic radical may be saturated or unsaturated and may be chained or branched. As in the case of the nonionic surfactants, mixtures of fatty acids such as those derived from natural sources such as sebum fatty acid, coconut fatty acid, can also be used.

Eksempler på fedtsyrer, hvoraf det stabiliserende aluminiumsalt kan dannes, indbefatter decansyre, dodecansyre, palmitin-syre, myristinsyre, stearinsyre, oliesyre, eicosansyre, talgfedtsyre, kokosfedtsyre, blandinger af disse syrer osv.. Alu-30 miniumsaltene af disse syrer findes i almindelighed i handelen og anvendes fortrinsvis i trisyref ormen, f.eks. aluminiums tea- DK 168637 B1 25 rat som aluminiumtristearat Al(C17H33C00)3. Monosyresaltene, f.eks. aluminiummonostearat Al (OH) 2 (C17H35COO) og disyresaltene, f.eks. aluminiumdistearat Al(OH)(C17H35COO)2, og blandinger af to eller tre af mono-, di- og trisyrealuminiumsaltene 5 kan også anvendes. Det foretrækkes dog mest at trisyrealumini-umsaltet udgør mindst 30%, fortrinsvis mindst 50%, og især mindst 80% af den samlede mængde aluminiumfedtsyresalt.Examples of fatty acids from which the stabilizing aluminum salt can be formed include decanoic acid, dodecanoic acid, palmitic acid, myristic acid, stearic acid, oleic acid, eicosanoic acid, tallow fatty acid, coconut fatty acid, mixtures of these acids, etc. and is preferably used in the triacid worm, e.g. aluminum theate as aluminum tristearate Al (C17H33C00) 3. The mono acid salts, e.g. aluminum monostearate Al (OH) 2 (C17H35COO) and the diacid salts, e.g. aluminum distearate Al (OH) (C17H35COO) 2, and mixtures of two or three of the mono-, di- and trisal aluminum salts 5 may also be used. However, it is most preferred that the trisyreal aluminum salt constitutes at least 30%, preferably at least 50%, and especially at least 80% of the total amount of aluminum fatty acid salt.

Aluminiumsaltene er som ovenfor nævnt industrielt tilgængelige og kan let fremstilles, f.eks. ved at forsæbe fedtsyre, f.eks.As mentioned above, the aluminum salts are industrially available and can be readily prepared, e.g. by saponifying fatty acid, e.g.

10 dyrisk fedt, stearinsyre osv., og derefter behandle den fremkommende sæbe med alun, aluminiumoxid osv..10 animal fat, stearic acid, etc., and then treat the emerging soap with alum, alumina, etc.

Der kræves kun meget små mængder af det- stabiliserende aluminiumsalt for at opnå en forbedring i fysisk stabilitet.Only very small amounts of destabilizing aluminum salt are required to improve physical stability.

Blegeaktivatoren reagerer i reglen med peroxygenforbindelsen til dannelse af et peroxysyreblegemiddel i vaskevandet. Det foretrækkes at inkludere et kompleksbindingsmiddel med høj 10 kompleksbindingsevne for at hindre en eventuel uønsket reaktion mellem denne peroxysyre og hydrogenperoxid i vaskeopløsningen i nærværelse af metalioner.The bleach activator usually reacts with the peroxygen compound to form a peroxyacid bleach in the wash water.

20 For at undgå tab af peroxidblegemiddel, f.eks. natriumperbo-rat, der skyldes enzyminduceret dekomponering, såsom med cata-laseenzym, kan midlerne desuden indeholde en enzyminhibitor-forbindelse, dvs. en forbindelse der er i stand til at hæmme enzyminduceret dekomponering af peroxidblegemidlet. Egnede in-25 hibitorforbindelser er beskrevet i US-patent nr. 3.606.990.20 To avoid loss of peroxide bleach, e.g. In addition, sodium perborate due to enzyme-induced decomposition, such as with catalase enzyme, the agents may contain an enzyme inhibitor compound, i. a compound capable of inhibiting enzyme-induced decomposition of the peroxide bleach. Suitable inhibitor compounds are disclosed in U.S. Patent No. 3,606,990.

Det foretrækkes dog at midlerne, som danner peroxysyre i vaskebadet (f.eks. midler indeholdende peroxygenforbindelse og aktivator 30 derfor) , er i hovedsagen fri for sådanne forbindelser og andre silikater. Det har f.eks. vist sig, at siliciumdioxid og silikater fremmer den uønskede dekomponering af peroxysyren.3,630,929, in amounts of 0 *, 1 - 10%, e.g. 1 - 5%. However, it is preferred that the agents which form peroxyacid in the wash bath (for example, agents containing peroxygen compound and activator 30) are substantially free of such compounds and other silicates.

DK 168637 B1 29 I en udførelsesform ifølge opfindelsen forbedres stabiliteten af buildersaltene i midlet under lagring og dispergerbarheden af midlet i vand ved at formale og reducere partikelstørrelsen af de faste buildere til mindre end 100 μτη, fortrinsvis mindre 5 end 40 /mi og mere foretrukket til mindre end 10 μτη. De faste buildere, f.eks. natriumtripolyphosphat (TPP), leveres i almindelighed i partikelstorrelser på ca. 100, 200 eller 400 μπι. Den ikke-ioniske flydende overfladeaktive fase kan blandes med de faste buildere før eller efter udførelsen af formalingsope-10 rationen.In an embodiment of the invention, the stability of the builder salts in the agent during storage and the dispersibility of the agent in water is improved by grinding and reducing the particle size of the solid builders to less than 100 μτη, preferably less than 40 µm and more preferably to less than 10 μτη. The fixed builders, e.g. sodium tripolyphosphate (TPP), is generally supplied in particle sizes of approx. 100, 200 or 400 μπι. The nonionic liquid surfactant phase can be mixed with the solid builders before or after the grinding operation is performed.

I en foretrukken udførelsesform ifølge opfindelsen underkastes blandingen af flydende ikke-ionisk overfladeaktivt stof og faste bestanddele for en mølle af afslidningstypen, hvori partikelstørrelserne af de faste bestanddele reduceres til 15 mindre end ca. 10 μτη, f.eks. til en gennemsnitspartikelstørrelse på 2 - 10 μτη eller endnu lavere (f.eks. 1 μτη) . Fortrinsvis har mindre ca. 10%, især mindre end 5% af alle de suspenderede partikler partikelstørrelser større end 10 μτη. Midler, hvis dispergerede partikler har en sådan lille størrelse, har 20 forbedret stabilitet mod adskillelse eller udfældning ved lagring. Tilsætning af den syreafsluttede ikke ioniske overfladeaktive forbindelse kan nedsætte flydespændingen af sådanne dispersioner og hjælpe til dispergerbarheden af dispersionerne uden et tilsvarende fald i dispersionens stabilitet 25 mod udfældning.In a preferred embodiment of the invention, the mixture of liquid nonionic surfactant and solids is subjected to an abrasion-type mill in which the particle sizes of the solids are reduced to less than ca. 10 μτη, e.g. to an average particle size of 2 - 10 μτη or even lower (eg 1 μτη). Preferably, less has approx. 10%, especially less than 5% of all the suspended particles, particle sizes greater than 10 μτη. Agents whose dispersed particles are of such a small size have improved stability against separation or precipitation upon storage. Addition of the acid-terminated non-ionic surfactant can reduce the flow stress of such dispersions and aid in the dispersibility of the dispersions without a corresponding decrease in the dispersion stability against precipitation.

Ved formalingsoperationen foretrækkes det at mængden af faste bestanddele er tilstrækkelig høj (f.eks. mindst ca. 40%, såsom ca. 50%) til at de faste partikler er i kontakt med hinanden og ikke væsentligt afskærmes mod hinanden af den ikke-ioniske 30 overfladeaktive væske. Efter formalingstrinnet kan eventuelt resterende flydende ikke-ionisk overfladeaktivt stof sættes til det formalede præparat. Møller, der anvender formalingskugler (kuglemøller) eller lignende bevægelige formalingselementer, har givet meget gode resultater. Man kan således an-35 vende en laboratoriemølle, der har formalingskugler af stea- DK 168637 B1 30 tit, med en diameter på 8 tran. Til arbejde i stor målestok kan anvendes en kontinuerligt virkende mølle, hvori der er formalingskugler med en diameter på 1 mm eller 1,5 mm, og som arbejder i et meget lille mellemrum mellem en stator og en ro-5 tor, der går med forholdsvis stor hastighed (f .eks. en CoBall-mølle) . Når der anvendes en sådan mølle, er det hensigtsmæssigt at lede blandingen af ikke-ionisk overfladeaktivt stof og faste stoffer først gennem en mølle, der ikke bevirker en så fin formaling (f.eks. en colloidmølle), for at reducere parti-10 kelstørrelsen til mindre end 100 μπι (f.eks. til ca. 40 μπι) før formalingen til en gennemsnitspartikeldiameter under ca. 10 μπι i den kontinuerlige kuglemølle.In the grinding operation, it is preferred that the amount of solids is sufficiently high (e.g., at least about 40%, such as about 50%) for the solid particles to be in contact with each other and not substantially shielded from each other by the nonionic 30 surfactant. After the grinding step, any residual liquid nonionic surfactant may be added to the ground preparation. Mills using grinding balls (ball mills) or similar moving grinding elements have produced very good results. Thus, one can use a laboratory mill having grinding balls of stiffness, 8 mm diameter. For large-scale work, a continuously operating mill may be used which has grinding balls 1 mm or 1.5 mm in diameter and which operate at a very small space between a stator and a rotor running at high speed (e.g. a CoBall mill). When such a mill is used, it is convenient to first pass the mixture of nonionic surfactant and solids through a mill which does not cause such fine grinding (e.g., a colloid mill) to reduce the particle size. to less than 100 μπι (e.g., to about 40 μπι) before milling to an average particle diameter below ca. 10 µπι in the continuous ball mill.

I de foretrukne kraftigt virkende flydende tøjvaskemidler ifølge opfindelsen er typiske mængder (procent beregnet på den 15 samlede vægt af midlet, medmindre andet er anført) af bestanddelene som følger:In the preferred heavy duty liquid laundry detergents of the invention, typical amounts (percent by weight of the total weight of the agent, unless otherwise stated) of the ingredients are as follows:
