Firmaet Chas. Hude._ (54) Vandigt vaskemiddelkoncentrat.The company Chas. Skin._ (54) Aqueous detergent concentrate.
I erhvervsvaskerier bliver der i stor udstrækning benyttet kontinuerligt arbejdende automatiske vaskemaskiner, ved hvilke vaskemiddeldoseringen sker fuldautomatisk fra en forrådsbeholder. Her bliver vaskemidlerne i reglen tilsat som vandige koncentrater, på grund af at disse lettere transporteres og doseres. Men også ved manuel tilsætning af vaskemiddel muliggør flydende midler en hurtigere og samtidig nøjagtigere dosering. Ved anvendelse af færdigtilberedte vaskemidler, som foruden anioniske og specielt ikke-ionogene vaskeaktive stoffer, i stadig større mængder indeholder uorganiske salte, specielt vaskealkaiier og polymer-phosphater, fremkommer der dog i reglen separeringer og faseadskillelser, når faststofindholdet i den vandige forrådsopløsning overstiger 10 vægt$.In commercial laundries, continuous automatic washing machines are used to a large extent, in which the detergent dispensing takes place fully automatically from a storage container. Here, the detergents are usually added as aqueous concentrates because they are more easily transported and dosed. But even with the manual addition of detergent, liquid agents allow a faster and more accurate dosage. However, with the use of ready-made detergents which, in addition to anionic and especially nonionic detergents, contain increasingly inorganic salts, especially detergents and polymer phosphates, separations and phase separations usually occur when the solids content of the aqueous stock solution exceeds 10% by weight $.
Såfremt man vil undgå forstyrrelser, som skyldes vaskemiddelbestand- dele der afsættes, er man tvunget til enten at forsyne forrådsbehol- 2 141705 deren med kostbare omrøringsudstyr eller roteringsanordninger eller vedvarende at pumpe den højprocentige lud rundt i lukkede ledningssystemer, eller at fortynde forrådsopløsningen stærkere, hvilket kræver en hyppigere ludtilsætning eller installationen af større forrådsbeholdere . Også ved nedsættelse af tensidindholdet til mængder under 2-3% kan en for tydelig afblanding blive forhindret, men herved bliver vaskeresultatet dog forringet væsentligt. Dette er specielt tilfældet, når man væsentligt formindsker mængden af det særligt vaskevirksomme, i nærværelse af større elektrolytmængder til faseseparering let tilbøjelige, ikke-ionogene tensid. Et højere sæbeindhold kan ligeledes medføre forstyrrelser, da koncentraterne har tendens til at gelere ved lavere temperaturer, og kan forstoppe rørledningerne og pumper.In order to avoid disruptions caused by detergent constituents being deposited, one is either obliged to supply the storage container with expensive stirring equipment or rotary devices or to continuously pump the high percentage liquor into closed conduit systems, or to dilute the stock, requires a more frequent liquefaction or the installation of larger storage containers. Also, by reducing the surfactant content to amounts below 2-3%, a clear mixing can be prevented, but the washing result will however be significantly reduced. This is especially the case when substantially reducing the amount of the particular washing agent, in the presence of larger electrolyte amounts for phase separation, easily prone, nonionic surfactant. A higher soap content can also cause disruptions as the concentrates tend to gel at lower temperatures and can clog the pipelines and pumps.
Anvendelsen af kendte opløsningsfremmende midler, som alkalisaltene af alkylbenzensulfonsyrer med 1-3 carbonatomer i alkylkædeme, formår ikke at hindre faseadskillelsen. Det samme gælder for organiske med vand blandbare opløsningsmidler, som desuden på grund af de højere generalomkostninger og nødvendigheden af at installere beskyttelsesindretninger mod fordampning og antændelse, stiller spørgsmål ved det økonomiske. Heller ikke anvendelsen af de til faseadskillelse mindre tilbøjelige organisk bundne phosphater, som f. eks. beskrevet i DE-fremlæggelsesskrift nr. 1.010.220, eller større mængder af organiske sequestreringsmidler i stedet for de betydeligt billigere og de for spildvandet ikke belastende vaskealkalier, som soda eller natriumsilicat, kommer på tale til sådanne i storvaskerier almindelige vaskemidler.The use of known solution-promoting agents, such as the alkali salts of alkylbenzenesulfonic acids having 1-3 carbon atoms in the alkyl chains, is unable to prevent the phase separation. The same applies to organic water-miscible solvents, which, moreover, due to the higher general costs and the need to install protective devices against evaporation and ignition, raise questions about the economic. Nor does the use of the organic phase-bound phosphates less prone to phase separation, as described, for example, in DE Publication No. 1,010,220, or larger quantities of organic sequestering agents instead of the considerably cheaper and non-stressful washing alkali such as soda or sodium silicate, is common to such detergents in general laundries.
Fra DE fremlæggelsesskrift nr. 12 86 251 kendes vaskemiddelkoncentrater indeholdende vandige alkalisilicater af sammensætningen Na2<D: SiC>2 - 1:1 - 1:2,5, og som er fri for polyphosphater og derfor ikke kan opnå et phosphatholdigt middels optimale vaskeevne. Nærværelsen af polyphosphat i disse midler ville, som det anføres i spalte 1, nødvendiggøre den samtidige anvendelse af dyre lithiumsalte eller aminoalkylarylsulfonater. Som opløsningsfremmende midler foreslås alkalisulfonater af xylen, toluen, ethylenbenzen og isopropylbenzen eller n-amyl- eller n-hexylalkalisulfater. I eksemplerne anvendes dog kun de nævnte alkalisulfonater således, at man må gå ud fra, at midlerne ikke klarer sig uden sådanne tilsætninger. Midlerne indeholder desuden som skumforstærkende middel og yderligere opløsnings-fremmende midler, fortrinsvis fedtsyrealkylolamider. Udviklingen af 3 141705 store og stabile skummængder ved tilberedningen og tilførslen af vaskekoncentraterne senat ved vaskeprocessen er imidlertid i erhvervs-vaskerier udtrykkeligt uønsket, da det forstyrrer vaskeprocessens forløb. Alt i alt kan det konstateres, at DE-fremlæggelsesskriftet ikke angiver nogen brugbar lære vedrørende fremstillingen af stabile phosphatholdige og i automatiske vaskeanlæg anvendelige vaske-middeIkoncentrater.From DE-Specification No. 12 86 251, detergent concentrates containing aqueous alkali silicates of the composition Na 2 <D: SiC> 2 - 1: 1 - 1: 2.5 are known, which are free of polyphosphates and therefore cannot achieve an optimal washing ability of a phosphate-containing agent. The presence of polyphosphate in these agents would, as indicated in column 1, necessitate the concomitant use of expensive lithium salts or aminoalkylarylsulfonates. As solution promoting agents, alkali sulfonates of xylene, toluene, ethylene benzene and isopropylbenzene or n-amyl or n-hexylalkali sulfates are proposed. In the examples, however, only the said alkali sulphonates are used so as to assume that the agents do not do without such additives. The agents additionally contain as a foam enhancer and additional solvent-promoting agents, preferably fatty acid alkylolamides. However, the development of 3,141,705 large and stable foams in the preparation and application of the senate wash concentrates during the washing process is expressly undesirable in commercial laundries as it interferes with the course of the washing process. All in all, it can be found that the DE disclosure does not indicate any useful teachings regarding the preparation of stable phosphate-containing and detergent-usable detergent concentrates.
Ved opfindelsen bliver de ovennævnte ulemper undgået.In the invention, the above disadvantages are avoided.
Opfindelsen angår et til vaskning i afhærdet vand beregnet vandigt vaskemiddelkoncentrat, der foreligger som en 10-20 vægt%'s opløsning og er fri for organiske opløsningsmidler, organisk bundne phos®· phater og alkalisulfonater af xylen, toluen, ethylbenzen og isopro= pylbenzen,,og indeholdende højst 2 vægtdele (beregnet på 100 vægtdele faste stoffer) af organiske sequestreringsmidler, kendetegnet ved et på faststofindhold beregnet indhold af a) 3-25 vægtdele af mindst ét som natriumsalt foreliggende anionisk vaskeaktivt stof valgt blandt n-alkylbenzensulfonater med 9-13 car= bonatomer i alkylkæden og sæber med 12-22 carbonatomer og mindst ét ikke ionogent vaskeaktivt stof valgt blandt 4-15 ethylenglycol3 ethergruppeholdige n-alkylphenolpolyglycolethere med 6-12 carbon^ atomer i alkylgruppen og n-alkylpolyglycolethere med 12-18 carbon= atomer i alkylgruppe, hvorhos vægtforholdet af anionisk til ikke ionogent vaskeaktivt stof udgør 1:10-10:1, b) 40-95 vægtdele af en blanding af vaskealkalier bestående af soda, natriumsilicat af sammensætningen Na20:Si02 * 1:1 - 1:2 og pentana* triumtripolyphosphat, hvorhos forholdet soda:natriumsilicat udgør 5:1-1:2 (beregnet på vandfri salte), og mængden af pentanatriumtri= polyphosphatet i vaskealkalierne udgør 3-30 vægt%, c) 2-6 vægtdele af en primær ligekædet alkylsulfat med 6-10 carbon= atomer, som for mere end 40% består af n-octylsulfat i form af na*= trium- eller triethanolaminsaltet.The invention relates to an aqueous detergent concentrate intended for washing in cured water, which is present as a 10-20% by weight solution and is free of organic solvents, organically bound phosphates and alkali sulfonates of xylene, toluene, ethylbenzene and isopropylbenzene. and containing not more than 2 parts by weight (calculated on 100 parts by weight of solids) of organic sequestering agents, characterized by a content calculated on a solids content of a) 3 to 25 parts by weight of at least one sodium salt present anionic detergent selected from n-alkylbenzenesulfonates having 9-13 car = bon atoms in the alkyl chain and soaps with 12-22 carbon atoms and at least one non-ionic detergent selected from 4-15 ethylene glycol 3 ether group-containing n-alkylphenol polyglycol ethers with 6-12 carbon atoms in the alkyl group and n-alkyl polyglycol ethers with 12-18 carbon atoms in alkyl group wherein the weight ratio of anionic to non-ionic detergent is 1: 10-10: 1, b) 40-95 parts by weight of a mixture of wash alcohol alias consisting of soda, sodium silicate of the composition Na 2 O: SiO 2 * 1: 1 - 1: 2 and pentane * tri-tripolyphosphate, the ratio of soda: sodium silicate being 5: 1-1: 2 (calculated on anhydrous salts) and the amount of pentane sodium tri = polyphosphate in the washing alkalis, 3-30% by weight, c) 2-6 parts by weight of a primary straight chain alkyl sulfate having 6-10 carbon = atoms, which for more than 40% consists of n-octyl sulfate in the form of the Na * = trium or triethanolamine salt.
Sulfonatvaskeristoffet består fortrinsvis af n-alkylbenzensulfonat med 12 carbonatomer i alkylkæden.The sulfonate wash preferably consists of n-alkylbenzenesulfonate having 12 carbon atoms in the alkyl chain.
4 1417054 141705
Som yderligere Taskeråstoffer kommer sæber på tale. Sæberne er afledt af fedtsyrer af naturlig eller syntetisk oprindelse med 12-22, fortrinsvis 12-18 carbonatomer. Egnede er specielt sæber, der kan opnås af naturlige eller hærdede fedtsyrer, som kokos-, talg- eller pal-mekernefedtsyrer. Vægtforholdet mellem de ovennævnte sulfonater og sæbe udgør hensigtsmæssigt 10:1 til 1:20.As additional Tasker raw materials, soaps come to mind. The soaps are derived from fatty acids of natural or synthetic origin having 12-22, preferably 12-18 carbon atoms. Particularly suitable are soaps which can be obtained from natural or hardened fatty acids, such as coconut, tallow or palm-based fatty acids. The weight ratio of the above sulfonates to soap is suitably 10: 1 to 1:20.
De senere under (a) nævnte alkylphenolpolyglycolethere og alkylpoly= glycolethere er afledt af forbindelser med lige alkylkæde, idet de alkylaromatiske forbindelser indeholder 6-12, fortrinsvis 8-10 og de alifatiske forbindelser indeholder 10-22, fortrinsvis 12-18 car= binatomer i alkylkæden. Antallet af ethylenglycolethergrupperne udgør ved begge forbindelsestyper gennemsnitlig 4-15. Der anvendes fortrinsvis blandinger af forbindelser med højere og lavere ethoxy= leringsgrad, fortrinsvis sådanne blandinger, som indeholder en alkyl= phenolpolyglycolether med gennemsnitlig 4-6 glycolethergrupper og en sådan med gennemsnitlig 8-12 glycolethergrupper i mængdeforholdet 2:1 til 1:2.The alkylphenol polyglycol ethers and alkyl poly glycol ethers later mentioned under (a) are derived from straight alkyl chain compounds, wherein the alkyl aromatic compounds contain 6-12, preferably 8-10, and the aliphatic compounds contain 10-22, preferably 12-18 carbine atoms. alkyl chain. The number of ethylene glycol ether groups averages 4-15 for both types of compounds. Preferably, mixtures of compounds having higher and lower ethoxylation rates are used, preferably such mixtures containing an alkyl = phenol polyglycol ether having an average of 4-6 glycol ether groups and one having an average of 8-12 glycol ether groups in the ratio 2: 1 to 1: 2.
Som vaskealkalier kommer blandinger af natriumcarbonat, natriumsili= cat og pentanatriumtriphosphat på tale. Natriumsilicatet skal have et forhold af Itø^OsSiC^ på 1:1 - 1:2. ^2310^/ 5 I^O har vist sig særlig velegnet, da det let lader sig håndtere. Blandingsforholdet af natriumcarbonat til natriumsilicat udgør, beregnet på vandfri salte, 5:1 - 1:2. Pentanatriumphosphatmængden udgør 3 til maksimalt 30 vægt% af vaskealkalien. Dette forholdsvis ringe indhold virker positivt på vaskeresultatet og gunstigt på spildvandsbelastningen.As washing alkali, mixtures of sodium carbonate, sodium silicate and pentane sodium triphosphate come into play. The sodium silicate must have a ratio of Ito ^ OsSiC ^ of 1: 1 - 1: 2. ^ 2310 ^ / 5 I ^ O has proved particularly suitable as it is easily manageable. The sodium carbonate to sodium silicate blend ratio, based on anhydrous salts, is 5: 1 - 1: 2. The amount of pentane sodium phosphate amounts to 3 to a maximum of 30% by weight of the wash potassium. This relatively low content has a positive effect on the washing result and favorable on the wastewater load.
Det under (c) nævnte i blandingen i en mængde på 2-6 vægtdele indeholdte alkylsulfat består for mere end 40% af n-octylsulfat. Eksempler på yderligere alkylsulfater, som kan foreligge i blanding med octylsulfat, er n-hexylsulfat, n-heptylsulfat, n-nonylsulfat og n-decylsulfat. n-alkylsulfaterne foreligger i form af natriumsalte eller triethanolaminsalte. De forhindrer, at vandige koncentrater af midlerne ifølge opfindelsen indtil et faststofindhold på 20 vægt% afblandes eller stivner til ikke-hældbare masser.The (c) mentioned in the mixture in an amount of 2-6 parts by weight of alkyl sulfate comprises more than 40% of n-octyl sulfate. Examples of additional alkyl sulfates which may be present in admixture with octyl sulfate are n-hexyl sulfate, n-heptyl sulfate, n-nonyl sulfate and n-decyl sulfate. The n-alkyl sulfates are in the form of sodium salts or triethanolamine salts. They prevent aqueous concentrates of the compositions of the invention up to a solids content of 20% by weight or blend into non-pourable masses.
Som eksempler på yderligere bestanddele, der eventuelt kan indgå i midlerne skal nævnes: Gråningsinhibitorer, specielt natriumsaltet af carboxymethylcellulose, der kan forefindes i mængder fra 0,1 til 5 141705 2 vægtdele, yderligere optiske klaremidler, specielt sådanne med formlen: ØtQttQtC)Examples of additional constituents which may be included in the compositions should be mentioned: Gray inhibitors, especially the sodium salt of carboxymethyl cellulose, which may be present in amounts from 0.1 to 5 parts by weight, additional optical clarifiers, especially those of the formula: ØtQttQtC)

Særligt egnede er sådanne forbindelser med den foregående formel, som natriumsalte, hvori X betegner en anilinogruppe og I betegner en methylamino-, diethanolamino- eller morpholinogruppe. Yderligere egnede klaremidler er f.eks. sådanne af typen naphthotriazolstilben= sulfonater, ethylen-bis-benzimidazoler, ethylen-bis-benzoxazoler, dialkylaminocumariner og carbostyriler. Mængden af klaremiddel udgør i almindelighed 0,01 - 0,3 vægt$ af vaskemidlet beregnet som fast stof.Wherein X and Y are as follows: NHg, NH-CH2, NH-CHg-CHgOH, CH2 -N-CHg-CH2OH, NCCHg-CHgOlOg, morpholino, dimethylmorpholino, NH-CgH ^, NH-CgH SO ^ H, where X and Y may be the same or different. Particularly suitable are such compounds of the foregoing formula as sodium salts, wherein X represents an anilino group and I represents a methylamino, diethanolamino or morpholino group. Further suitable clarifiers are e.g. such as the naphthotriazole-style benzulfonates, ethylene-bis-benzimidazoles, ethylene-bis-benzoxazoles, dialkylamino-coumarins, and carbostyrils. The amount of detergent generally amounts to 0.01 - 0.3 wt.% Of the detergent calculated as a solid.
lil stabilisering af det optiske klare middel kan der yderligere tilsættes sequestreringsmidler, specielt natriumethylendiaminotetraace= tat i mængder på 0,1 - 2 vægtdele. Yderligere kan der også forefindes natriumsalte, som natriumsulfat, f.eks. i mængder på indtil 10 vægtdele.In order to stabilize the optically clear agent, sequestering agents, especially sodium ethylenediaminotetraacetate, may be added in amounts of 0.1 to 2 parts by weight. Further, sodium salts, such as sodium sulfate, e.g. in quantities up to 10 parts by weight.
Vaskemiddelkompositionen ifølge opfindelsen foreligger som et vandigt koncentrat med et faststofindhold på 10-20 vægt%. Det udmærker sig ved, at det ikke har tendens til faseseparering eller udskillelse af faste indholdsstoffer. Blandinger med højere sæbeindhold, dvs. sådanne med 10 og flere vægtdele sæbe, har heller ikke ved lavere temperaturer i form af vandige koncentrater tendens til at gelere. Midlerne besidder en høj rensevirkning, kan let nedbrydes ad biologisk vej og fører, på grund af deres forholdsvis ringe phosphatindhold og fraværelsen af nævneværdige mængder af chelat-dannere heller ikke under u-gunstige spildevandsbetingelser, ikke til en forstyrrende belastning af kloakvandet.The detergent composition of the invention is available as an aqueous concentrate having a solids content of 10-20% by weight. It is distinguished by the fact that it does not tend to phase separation or the excretion of solids. Higher soap blends, ie. those with 10 and more parts by weight of soap also do not tend to gel at lower temperatures in the form of aqueous concentrates. The agents have a high purification effect, can be readily degraded by biological means and, due to their relatively low phosphate content and the absence of appreciable amounts of chelating agents, do not, under unfavorable wastewater conditions, also lead to a disruptive load on the sewage.
