Fra DK fremlæggelsesskrift nr. 154.827 (svarende til GB pa-entskrift nr. 2.005.715) (Colgate-Palmolive) kendes et phos-phatfrit vaskemiddel, som omfatter en vandopløselig nonionisk detergent samt zeolit som erstatning for phosphat, hvor den 20 nonioniske detergent er absorberet på forstøvningstørrede perler omfattende en blanding af zeolit og enten natriumcarbonat eller en blanding af natriumcarbonat og natriumbicarbonat. De i skriftet angivne vaskemiddelforskrifter er karakteristiske ved ikke at indeholde kompleksbindere som phosphonater, EDTA 25 og ej heller polymere bestanddele eller citrater. I skriftet nævnes intet vedrørende reduceret inkrustation/udfældning.From DK Offenlegungsschrift No. 154,827 (corresponding to GB pa-entskrift no. 2,005,715) (Colgate-Palmolive) a phosphate-free detergent is known which comprises a water-soluble nonionic detergent and zeolite as a substitute for phosphate, where the 20 nonionic detergent is absorbed on spray-dried beads comprising a mixture of zeolite and either sodium carbonate or a mixture of sodium carbonate and sodium bicarbonate. The detergent specifications set forth in the specification are characterized in that they do not contain complex binders such as phosphonates, EDTA 25 nor polymeric constituents or citrates. The document does not mention anything regarding reduced incrustation / precipitation.

Fra DK fremlæggelsesskrift nr. 151.231 (Henkel) (svarende til GB patentskrift nr. 1.473.201) kendes et vaskemiddel omfatten-3 0 de vanduopløseligt, fi ndelt al umi ni umsilikat (zeolit) samt mindst én bestanddel valgt blandt tensider, builderstoffer og blegemidler, hvilket vaskemiddel som phosphaterstatningsstof indeholder krystallinsk eller røntgenamorft aluminiumsilikat (zeolit). I eksempel 9 i skriftet er der angivet en recept på 35 et zeolitbaseret vaskemiddel, hvor det anvendte tensid udelukkende er et noniontensid. Det blegemiddelholdige vaskemiddel indeholder tillige natriumcitrat, silikat samt smudssuspende- DK 167363 B1 3 ringsmiddel. Produktet indeholder imidlertid ikke polymere forbindelser. Det skal hertil bemærkes, at der ikke er angivet specifikke resultater for anvendelsen af dette vaskemiddel, og at der intet nævnes vedrørende sammenhæng mellem valg af ten-5 sider og formulering og inkrustati oner samt udfældninger på varme 1 egenier.From DK Offenlegungsschrift No. 151,231 (Henkel) (corresponding to GB Patent Specification No. 1,473,201) a detergent is known to comprise water-insoluble, finely divided al umi ni unsilicate (zeolite) and at least one constituent selected from surfactants, builders and bleaches , which detergent as phosphate substitute contains crystalline or X-ray amorphous aluminosilicate (zeolite). Example 9 of the specification discloses a recipe for a zeolite-based detergent in which the surfactant used is exclusively a nonionic surfactant. The bleach-containing detergent also contains sodium citrate, silicate and soil suspending agent. However, the product does not contain polymeric compounds. It should be noted in this connection that no specific results have been stated for the use of this detergent, and that nothing is mentioned regarding the connection between the choice of ten-sides and formulation and incrustations as well as precipitates on hot 1 properties.

Fra DK fremlæggelsesskrift nr. 156.173 (Henkel) (svarende til GB patentskrift nr. 1.473.202), hvilket skrift er et tillægs-10 patent til ovennævnte DK fremlæggelsesskrift nr. 151.231 (Henkel), kendes et zeolitbaseret vaskemiddel som beskrevet i DK fremlæggelsesskriftet nr. 151.231, hvor tensidkomponenten består af 1 vægtdel nonionisk tensid og 0-3 vægtdele anionisk tensid. I eksempel 7 ses et eksempel på en zeolitbaseret va-15 skemiddelrecept, hvori andelen af anionisk tensid er 0, dvs. hvor tensidet udelukkende er et nonionisk tensid. Der nævnes ingen specifikke vaskeresultater for dette eksempel, og heller ikke her er noget steds i skriftet omtalt en sammenhæng mellem valg af tensid og formulering og inkrustationer og udfældnin-20 ger på varmelegemer.From DK presentation document no. 156,173 (Henkel) (corresponding to GB patent specification no. 1,473,202), which publication is an additional patent to the above-mentioned DK presentation document no. 151,231 (Henkel), a zeolite-based detergent is known as described in DK presentation document no. 151,231, wherein the surfactant component consists of 1 part by weight of nonionic surfactant and 0-3 parts by weight of anionic surfactant. Example 7 shows an example of a zeolite-based detergent recipe in which the proportion of anionic surfactant is 0, i.e. wherein the surfactant is exclusively a nonionic surfactant. No specific washing results are mentioned for this example, nor is here anywhere in the text mentioned a connection between the choice of surfactant and formulation and incrustations and precipitations on heaters.

Fra EP offentliggørelsesskrift nr. 243.908 (Henkel) kendes et phosphatfrit, granulært vandblødgøringsmiddel , som omfatter 50-60 vægt% fint krystallinsk zeolit, 3,5-5 vægt% natriumsalt 25 af polyacrylsyre eller polymethacrylsyre eller en copolymer af disse syrer med maleinsyre, 4-15 vægt% natriumcitrat, 4-12 vægt% natriumcarbonat, 0-2 vægt% natriumcarboxymethylcellulose og 12-25 vægt% vand. Dette vandblødgøringsmiddel er tilpasset til anvendelse i kombination med et traditionelt tøjvaskemid-30 del i tilfælde af hårdt vaskevand. EP offentliggørelsesskriftet giver dog ingen anvisninger med hensyn til de krav, der stilles til tens idkomponenten i et tøjvaskemiddel, der skal anvendes sammen med vandblødgøringsmidlet for at undgå aflejringer på vaskemaskinens varmelegemer eller inkrustationer i 35 tekstilerne, når man anvender en lav dosering, sådan som det typisk er tilfældet i tilfælde af et vaskemiddel af den såkaldte kompakttype.EP Publication No. 243,908 (Henkel) discloses a phosphate-free granular water softener comprising 50-60% by weight of fine crystalline zeolite, 3.5-5% by weight of sodium salt of polyacrylic acid or polymethacrylic acid or a copolymer of these acids with maleic acid, 4 -15% by weight of sodium citrate, 4-12% by weight of sodium carbonate, 0-2% by weight of sodium carboxymethylcellulose and 12-25% by weight of water. This water softener is suitable for use in combination with a traditional laundry detergent in case of hard wash water. However, the EP publication does not provide any guidance as to the requirements for the tens id component of a laundry detergent to be used with the water softener to avoid deposits on the washing machine heaters or incrustations in the textiles when using a low dosage such as the typically this is the case in the case of a detergent of the so-called compact type.

Fra DK patentansøgning nr. 834/86 (Procter & Gamble) kendes et vaskemiddel, der indeholder 5-50 vægt% zeolit og 0,1-20 vægt% pol yearboxy1 atpol ymer. I nogle af eksemplerne indeholder vaskemidlet også nitrilotrieddikesyre, men i disse eksempler in-5 deholder tensidkomponenten en betydelig mængde aniontensider, ca. 42 til 90 vægt% af den samlede tens idkomponent kombineret ’ med kun en moderat mængde noniontensid, på ca. 10-49 vægt%. Aniontensider vides at give phosphatfrie tøjvaskemidler en fremragende rengøringsevne, men de giver problemer i tilfælde IC af lav dosering ved anvendelse af vaskemidler af kompakttypen.From DK patent application no. 834/86 (Procter & Gamble) a detergent is known which contains 5-50% by weight of zeolite and 0.1-20% by weight of pol yearboxy1 atpol ymer. In some of the examples the detergent also contains nitrilotriacetic acid, but in these examples the surfactant component contains a significant amount of anion surfactants, approx. 42 to 90% by weight of the total tensile component of the total compound combined ’with only a moderate amount of nonionic surfactant, of approx. 10-49% by weight. Anionic surfactants are known to provide phosphate-free laundry detergents with excellent cleaning ability, but they present problems in the case of low dose ICs using compact type detergents.

Ved anvendelsen af konventionelle tøjvaskemidler vil den mængde af det anvendte vaskemiddel, som behøves til opnåelse af et tilfredsstillende vaskeresultat, være afhængig af vaskevandets 15 hårdhed.In the use of conventional laundry detergents, the amount of detergent used needed to obtain a satisfactory washing result will depend on the hardness of the washing water.

Hvis man således anvendte den samme dosis vaskemiddel uden at tage hensyn til vandets hårdhed, vil calciumioner og magnesiumioner i hårdt vaskevand bevirke en markant reduktion af den 20 opnåede vaskeeffekt. Dertil kommer, at calciumioner og magnesiumioner kan give anledning til aflejringer både i form af kalkaflejringer på den anvendte vaskemaski nes varmelegemer og i form af såkaldte inkrustationer, dvs. aflejringer i vasketøjet, som kan blive siddende i vasketøjet, og således vil blive 25 akkumuleret, når man vasker tøjet flere gange.Thus, if the same dose of detergent was used without taking into account the hardness of the water, calcium ions and magnesium ions in hard wash water will cause a marked reduction in the washing effect obtained. In addition, calcium ions and magnesium ions can give rise to deposits both in the form of limescale deposits on the heaters of the washing machine used and in the form of so-called incrustations, ie. deposits in the laundry which may remain in the laundry and thus will be accumulated when washing the laundry several times.

Sådanne problemer med aflejringer kan både forekomme, når der anvendes phosphatholdige vaskemidler, og når der anvendes phosphatfrie vaskemidler. Det er dog især ved anvendelse af de 30 phosphatfrie vaskemidler, at kalkaflejringerne på varmelegemerne og inkrustationer i vasketøjet kan være et problem. Årsagen til dette er, at de komponenter, der traditionelt anvendes i stedet for phosphat ved formulering af phosphatfrie vaskemidler, ikke har nær så gode vasketekniske egenskaber som 35 phosphat og ikke binder og/eller dispergerer de hårdhedsskabende calcium- og magnesiumioner nær så effektivt. Ved formulering af phosphatfrie vaskemidler er man derfor ofte nødt til DK 167363 B1 5 at kombinere en række forskellige komponenter som erstatning for phosphat for at opnå et tilstrækkeligt effektivt tøjvaskemiddel. Således formuleres zeolitbaserede bui1dersystemer generelt med en række andre komponenter, som hver især bidrager 5 med forskellige vaskeegenskaber, hvilket gør det mere vanskeligt at formulere phosphatfrie vaskemidler. Særligt vanskeligt er formuleringen af de såkaldte kompakte, phosphatfrie vaskemidler, som i de senere år er kommet frem på det europæiske marked. Grunden hertil er, at dosis pr. vask hos kompakte, 10 phosphatfrie vaskemidler er markant reduceret i forhold til tidligere.Such deposition problems can occur both when using phosphate-containing detergents and when using phosphate-free detergents. However, it is especially with the use of the 30 phosphate-free detergents that the limescale deposits on the heaters and incrustations in the laundry can be a problem. The reason for this is that the components traditionally used instead of phosphate in the formulation of phosphate-free detergents do not have nearly as good washing properties as phosphate and do not bind and / or disperse the hardening calcium and magnesium ions nearly as effectively. When formulating phosphate-free detergents, it is therefore often necessary to combine a number of different components as a substitute for phosphate in order to obtain a sufficiently effective laundry detergent. Thus, zeolite-based buffer systems are generally formulated with a variety of other components, each of which contributes to different washing properties, making it more difficult to formulate phosphate-free detergents. Particularly difficult is the formulation of the so-called compact, phosphate-free detergents that have emerged on the European market in recent years. The reason for this is that the dose per washing with compact, 10 phosphate-free detergents is significantly reduced compared to before.

Imidlertid er den foreskrevne dosis af tøjvaskemidlet ifølge den forliggende opfindelse endnu lavere end de anbefalede do-15 ser af kompaktvaskemidlerne.However, the prescribed dose of the laundry detergent of the present invention is even lower than the recommended doses of the compact detergents.

Af hensyn til vasketøjets udseende vil man sædvanligvis højst kunne tillade et indhold af inkrustationer i tøjet på 1 vægt% for phosphatholdige vaskemidler (RAL RG 992: Giitezeichen flir 20 sachgemasse Wåschepf1 ege, Frankfurt, 1971), mens man generelt accepterer en noget ringere sekundær vaskeeffekt for phosphatfrie tøjvaskemidler og derfor har sat en højere maksimal grænse for inkrustationer i tøjet på 3% (H. Krlissman, P. Vogel; Seifen Ole Fette Wasche 111, 333 (1985)). Dette er en opvej-25 ning af de store miljømæssige fordele, der opnås med phosphatfrie vaskemidler.Due to the appearance of the laundry, it will usually be possible to allow a maximum content of incrustations in the laundry of 1% by weight for phosphate-containing detergents (RAL RG 992: Giitezeichen flir 20 sachgemasse Wåschepf1 ege, Frankfurt, 1971), while generally accepting a somewhat lower secondary washing effect. for phosphate-free laundry detergents and therefore has set a higher maximum limit for incrustations in clothing of 3% (H. Krlissman, P. Vogel; Seifen Ole Fette Wasche 111, 333 (1985)). This is a balance of the great environmental benefits obtained with phosphate-free detergents.

For at forhindre kalkaflejringer og inkrustationer vil man ofte anvende en større mængde af vaskemidlet, dersom det 30 anvendte vaskevand er hårdt. Dette medfører imidlertid et overdrevent forbrug af tensider samt andre miljøbelastende komponenter, og de senere år er samfundet og den enkelte borger netop blevet opmærksom på de uheldige miljømæssige og ressourcemæssige konsekvenser af et uhensigtsmæssigt overforbrug 35 af tensidholdige produkter. En anden måde at forhindre kalkaflejringer og inkrustationer på end ved at forøge mængden af anvendt vaskemiddel er, at man sammen med vaskemidlet benytter DK 167363 B1 6 et såkaldt vandblødgøringsmiddel, hvorved vaskemidlet kan anvendes i den samme lave dosis, som når vaskevandet er blødt.To prevent limescale deposits and incrustations, a larger amount of the detergent will often be used if the wash water used is hard. However, this leads to an excessive consumption of surfactants as well as other environmentally harmful components, and in recent years society and the individual citizen have just become aware of the unfortunate environmental and resource consequences of an inappropriate overconsumption 35 of surfactant-containing products. Another way to prevent limescale deposits and incrustations than by increasing the amount of detergent used is to use a so-called water softener with the detergent, whereby the detergent can be used in the same low dose as when the wash water is soft.

En sådan vandblødgører indeholder sædvanligvis buildere og sekvestreringsmidler, som blødgør vandet ved at neutralisere 5 eller binde calciumioner og magnesiumioner.Such a water softener usually contains builders and sequestrants which soften the water by neutralizing or binding calcium ions and magnesium ions.

Selv om en sådan anvendelse af en separat vandblødgører teknisk og mil jømæssi gt set er en udmærket løsning, kan den i praksis vise sig at være besværlig, og der er en risiko for, 10 at brugeren anvender en ukorrekt dosering og således ikke opnår det ønskede resultat. Vaskemiddelfabrikanten er nødt til at distribuere både et vaskemiddel og et vandblødgøringsmid-del. Detailhandleren må have lagerplads til sådanne to produkter, og også forbrugeren har besvær med at skulle have 15 plads til og anvende to produkter ved hver vask. Dertil kommer, at både fabrikanten og detailhandleren har en vanskelig opgave med hensyn til at instruere forbrugeren om den korrekte anvendelse. Selv hvis der på emballagen er angivet en omhyggelig brugsanvisning vedrørende den korrekte anvendelse, vil det 20 stadig være vanskeligt for forbrugeren at vurdere den korrekte dosering af vandblødgører, idet oplysningerne om det lokale ledningsvands hårdhed kan være vanskelige eller umulige at fremskaffe.Although such use of a separate water softener is technically and environmentally sound an excellent solution, in practice it can prove to be cumbersome and there is a risk that the user uses an incorrect dosage and thus does not achieve the desired result. The detergent manufacturer has to distribute both a detergent and a water softener. The retailer must have storage space for such two products, and also the consumer has trouble having to have 15 space for and use two products at each wash. In addition, both the manufacturer and the retailer have a difficult task in instructing the consumer on the correct use. Even if the packaging provides careful instructions for proper use, it will still be difficult for the consumer to assess the correct dosage of water softener, as the information on the hardness of the local tap water may be difficult or impossible to obtain.

25 Uanset om der anvendes vandblødgører eller en forøget mængde af selve vaskemidlet, vil forbrugeren i tilfælde af usikkerhed være tilbøjelig til at forøge dosis af vandblødgører og/eller vaskemiddel, hvilket er uheldigt af såvel miljømæssige som ressourcemæssige grunde.Regardless of whether water softener is used or an increased amount of the detergent itself, in case of uncertainty, the consumer will tend to increase the dose of water softener and / or detergent, which is unfortunate for both environmental and resource reasons.

3030

Der er således et behov for et tøjvaskemiddel, der uanset vaskevandets hårdhed ved anvendelse af en markant lavere mængde af vaskemidlet end normalt giver et effektivt vaskeresultat uden problemer med aflejringer på vaskemaskinens varmelegemer 35 og inkrustationer i vasketøjet.Thus, there is a need for a laundry detergent which, regardless of the hardness of the washing water using a significantly lower amount of the detergent than usual, provides an effective washing result without problems with deposits on the washing machine heaters 35 and incrustations in the laundry.

Det anses for at være et væsentligt træk ved vaskemidlet ifølge opfindelsen, at tens idkomponenten overvejende udgøres af non iontens id. Det er lige så væsen11igt, at det ikke indeholder forstyrrende mængder af anionisk tensid, idet sådanne vil 25 danne uopløselige forbindelser ved højere vandhårdhedsgrader, hvilket giver en forringelse af vaskeevnen.It is considered to be an essential feature of the detergent according to the invention that the tens ID component is predominantly constituted by the non ion ID. It is equally important that it does not contain interfering amounts of anionic surfactant, as such will form insoluble compounds at higher water hardness levels, resulting in a deterioration of the washability.

Udover noniontensid kan tens idkomponenten derimod godt indeholde andre tensider af ikke-anionisk art, såsom alle kendte 3Q typer af amfotere, amfolytiske og zwitterioniske overfladeaktive forbindelser, sædvanligvis dog højst 50% af tensidmængden. Eksempler herpå er indgående omtalt i US-patentskrift nr. 4.111.855, US-patentskrift nr. 3.995.669 og GB-patentskrift nr. GB 2.075.043A.In addition to nonionic surfactant, on the other hand, the surfactant component may well contain other surfactants of a non-anionic nature, such as all known 3Q types of amphoteric, ampholytic and zwitterionic surfactants, but usually not more than 50% of the amount of surfactant. Examples of this are discussed in detail in U.S. Patent No. 4,111,855, U.S. Patent No. 3,995,669 and GB Patent No. GB 2,075,043A.

35 Særligt foretrukket blandt disse er et amfotert tensid i form af en pulverform i g type af kokosamidopropylbetain, der sælges under handelsnavnet "TEGOBETAIN" L-7, der leveres af Goldschmidt AG, Essen, Tyskland, hvilket produkt har et indhold af aktivt stof på 80%.Particularly preferred among these is an amphoteric surfactant in the form of a powdered type of coconut amidopropyl betaine sold under the trade name "TEGOBETAIN" L-7 supplied by Goldschmidt AG, Essen, Germany, which has an active substance content of 80%. %.

DK 167363 B1 12DK 167363 B1 12

Builder A omfatter zeolit og/el1 er lag-silikat og eventuelt også alkalimetalsi1ikat, såsom natriumsilikat. Således kan builder A f.eks. være sammensat af zeolit og natriumsilikat eller builder A kan udelukkende udgøres af lag-silikat. Det er 5 også muligt at anvende en kombination af zeolit, alkalimetalsil i kat og lag-silikat eller af zeolit og lag-si likat. Zeoli t og lag-si likat har ionbyttende egenskaber, mens alkalimetalsilikat, såsom natriumsilikat, underbygger den ionbyttende virkning. Dersom der som ionbyttende middel anvendes zeolit, 10 vil alkalimetalsi1ikat sædvanligvis være obligatorisk.Builder A comprises zeolite and / or 1 is layer silicate and optionally also alkali metal silicate, such as sodium silicate. Thus, builder A can e.g. be composed of zeolite and sodium silicate or builder A may be composed exclusively of layered silicate. It is also possible to use a combination of zeolite, alkali metal silica in cat and layer silicate or of zeolite and layer silicate. Zeolite and layer silicate have ion exchange properties, while alkali metal silicate, such as sodium silicate, underpins the ion exchange effect. If zeolite is used as the ion exchange agent, alkali metal silicate will usually be mandatory.

Når der anvendes en kombination af zeolit og natriumsilikat, anvendes der fortrinsvis 13-29 vægtdele natriumsilikat per 100 vægtdele zeolit, særligt foretrukket 15-27 vægtdele, endnu mere foretrukket 17-25 vægtdele, især 19-23 vægtdele natriumsilikat per 100 vægtdele zeolit. Det er også muligt at kombinere zeolit med en anden alkalisk builder.When a combination of zeolite and sodium silicate is used, preferably 13-29 parts by weight of sodium silicate per 100 parts by weight of zeolite, particularly preferably 15-27 parts by weight, even more preferably 17-25 parts by weight, especially 19-23 parts by weight of sodium silicate per 100 parts by weight of zeolite. It is also possible to combine zeolite with another alkaline builder.

Som zeolit (aluminiumsilikat) kan der i princippet anvendes 20 alle kendte typer af aluminiumsilikater. Eksempler på sådanne er nævnt i DK-fremlæggelsesskriftet nr. 151.231, DK-fremlæg-gelsesskriftet nr. 154.827 og i EP-offentiiggørelsesskriftet nr. 289.767.As zeolite (aluminosilicate), in principle all known types of aluminosilicates can be used. Examples of such are mentioned in DK submission document no. 151,231, DK submission letter no. 154,827 and in EP publication no. 289,767.

25 Særligt foretrukket som zeolitkomponent i tøjvaskemidlet ifølge opfindelsen er zeolit A med formlen Na^2 ((A1°2)12(Sl°2)12) x H2O, hvor x = 20-30, fortrinsvis x = 27.Particularly preferred as the zeolite component in the laundry detergent according to the invention is zeolite A of the formula Na 2 ((A1 ° 2) 12 (S1 ° 2) 12) x H 2 O, where x = 20-30, preferably x = 27.

Afhængigt af metoden til sammenblanding og viderebehandling af 30 tøjvaskemidlet ifølge opfindelsen, såsom f.eks. spraytørring af en omslæmning, tør- eller vådgranulering, kompakter i ng, ek-strudering etc., før en eventuel tablettering kan der udvælges zeolittyper med en for fremstillingsmetoden passende sammensætning, kornstørrelse, vægtfylde, opløselighed, absorberings-35 evne etc.Depending on the method of mixing and further processing the laundry detergent according to the invention, such as e.g. spray drying of an envelope, dry or wet granulation, compacts in ng, extrusion, etc., before any tableting, zeolite types can be selected with a composition suitable for the manufacturing method, grain size, density, solubility, absorbency, etc.

I tøjvaskemidlet ifølge opfindelsen, som fortrinsvis fremstilles ved en enkelt spray-mix-proces, anvendes fortrinsvis et højtabsorberende zeolitgranulat, såsom f.eks. det produkt, der sælges under handelsnavnet WESSALITH® CD, der leveres af DK 167363 B1 13In the laundry detergent according to the invention, which is preferably prepared by a single spray-mix process, a highly absorbent zeolite granulate, such as e.g. the product sold under the trade name WESSALITH® CD supplied by DK 167363 B1 13

Degussa AG, Frankfurt am Main, Tyskland. Produktet indeholder 71¾ zeolit A samt polycarboxylat og nonionisk tensid.Degussa AG, Frankfurt am Main, Germany. The product contains 71¾ zeolite A as well as polycarboxylate and nonionic surfactant.

Builder A kan desuden helt eller delvis bestå af såkaldte lag-5 silikater med den støkiometriske sammensætning Na2Si05, hvor de enkelte lag består af Si 04-tetraedre. En fordel ved lagsilikater er, at de i modsætning til aluminiumsilikaterne er i stand til også at binde magnesiumioner, som spiller en særlig rolle ved kalkafsætning på varmelegemer.Builder A can also consist wholly or partly of so-called layer-5 silicates with the stoichiometric composition Na 2 SiO 5, where the individual layers consist of Si 04 tetrahedra. An advantage of layered silicates is that, in contrast to the aluminum silicates, they are also able to bind magnesium ions, which play a special role in the deposition of lime on heaters.

10 I tøjvaskemidlet ifølge opfindelsen foretrækkes et lag-silikat i granulatform, som f.eks. sælges under handelsnavnet "SKS-6", der leveres af Hoechst AG, Frankfurt am Main, Tyskland.In the laundry detergent according to the invention, a layer of silicate in granular form, such as e.g. sold under the trade name "SKS-6" supplied by Hoechst AG, Frankfurt am Main, Germany.

15 I tøjvaskemidlet ifølge opfindelsen anvendes builder A sammen med builder B, der virker som ionoverførende middel (carrier), builder C, der virker som udfældningsbegrænsende middel (thresholder), samt builder D, der virker som smudssuspende-ri ngsmiddel.In the laundry detergent according to the invention, builder A is used together with builder B, which acts as an ion transfer agent (carrier), builder C, which acts as a precipitation limiting agent (threshing holder), and builder D, which acts as a soil suspending agent.

2020

Det ionoverførende middel (builder B) binder de hårdhedsdanende ioner og transporterer dem over til det ionbyttende middel, f.eks. zeolit, hvortil de videregives og bindes ved ionbytning. Herved blødgøres det hårde vand hurtigere end ellers, 25 idet zeolit alene har en relativ langsom blødgør ingseffekt baseret på ionbytning af hovedsageligt calciumioner. Dersom der som builder A anvendes en større mængde af lag-silikat i stedet for zeolit, vil den nødvendige mængde af ionoverførende middel (builder B) antageligvis kunne reduceres og muligvis 30 helt udelades.The ion transfer agent (builder B) binds the hardness-forming ions and transports them over to the ion exchange agent, e.g. zeolite to which they are passed and bound by ion exchange. This softens the hard water faster than otherwise, as zeolite alone has a relatively slow softening effect based on ion exchange of mainly calcium ions. If a larger amount of layer silicate is used as builder A instead of zeolite, the required amount of ion-transfer agent (builder B) can probably be reduced and possibly omitted altogether.

Som builder B i det omhandlede tøjvaskemiddel anvendes sædvanligvis citrat. Citratkomponenten kan bl.a. være i form af tri-natriumcitratdihydrat, vandfrit tri natriumcitrat samt vandfrit 35 mononatriumcitrat. Sidstnævnte type foretrækkes og leveres f.eks. af Citrique Beige Ltd., Tienen, Belgien. Der kan også anvendes citronsyre, nitrilotrieddikesyre (NTA) eller såkaldte DK 167363 B1 14 chelatiserende tensider, hvoraf de sidstnævnte har den fordel, at de er opløselige i fedtholdigt snavs (vedrørende chelatiserende tensider henvises til Novak et al., Seifen Ole Fette Wachse 111 (1985), 1.35-87) .As builder B in the present laundry detergent, citrate is usually used. The citrate component can i.a. be in the form of tri-sodium citrate dihydrate, anhydrous tri-sodium citrate and anhydrous monosodium citrate.

Ved fremstilling af tabletter kan man til forbedring af opløsningstiden anvende en kombination af citronsyre og natriumcar-bonat og/eller natriumbicarbonat, således at der opnås en bruseeffekt, når tabletterne kommer i kontakt med vand. I sådanne 10 tabletter kan andelen af citronsyre og derved builder B ligge i det øvre grænseområde, dvs. op til 55 vægtdele builder B per 100 vægtdele builder A. I vaskemidler ifølge opfindelsen, hvor der ikke ønskes en sådan bruseeffekt, vil mængden af builder B sædvanligvis være væsentligt mindre, f.eks. 3,7 til 15 12, fortrinsvis 6,2 til 9,2 og især 6,9 - 8,5 vægtdele builder B per 100 vægtdele builder A.In the manufacture of tablets, a combination of citric acid and sodium carbonate and / or sodium bicarbonate can be used to improve the dissolution time, so that a showering effect is obtained when the tablets come into contact with water. In such 10 tablets, the proportion of citric acid and thereby builder B may be in the upper limit range, i.e. up to 55 parts by weight of builder B per 100 parts by weight of builder A. In detergents according to the invention, where such a shower effect is not desired, the amount of builder B will usually be significantly less, e.g. 3.7 to 15 12, preferably 6.2 to 9.2 and especially 6.9 - 8.5 parts by weight of builder B per 100 parts by weight of builder A.

Under ionbytningen må kationer først diffundere ind i det ionbyttende middels indre hulrum, før der kan ske ionbytning.During ion exchange, cations must first diffuse into the inner cavity of the ion exchange agent before ion exchange can occur.

20 Dette betyder, at der kan opstå uheldige ioniske fældningsreaktioner, som bl.a. giver anledning til inkrustationer i og forgråning af vasketøjet.This means that adverse ionic precipitation reactions can occur, which i.a. gives rise to incrustations in and graying of the laundry.

Imidlertid kan tilsætning af builder C, dvs. de føromtalte 25 udfældningsbegrænsende midler, især i form af polymere carboxylsyrer, forhindre disse fældningsreaktioner gennem adsorp-tiv stabilisering af de kolloide mellemtrin, hvorved inkrusta-tionerne markant reduceres. En tilsvarende effekt opnås med visse kompleksbindere, f.eks. phosphonat og phytat, dog med en 30 anden virkningsmekanisme. Idet builder C fortrinsvis udgøres af polycarboxy1 at, kan man således også forestille sig, at en større eller mindre andel deraf udgøres af sådanne komp1eks-bi ndere. 1However, the addition of builder C, i.e. the aforementioned precipitation limiting agents, in particular in the form of polymeric carboxylic acids, prevent these precipitation reactions through adsorptive stabilization of the colloidal intermediate steps, whereby the incrustations are markedly reduced. A similar effect is obtained with certain complex binders, e.g. phosphonate and phytate, but with a different mechanism of action. Since builder C is preferably constituted by polycarboxyl, it can thus also be imagined that a larger or smaller proportion thereof is constituted by such complex binders. 1

højde med de bedste tøjvaskemidler på markedet. Det fremgår endvidere, at uanset om vandets hårdhed er på 20°dH, 25°dHheight with the best laundry detergents on the market. It also appears that regardless of whether the hardness of the water is 20 ° dH, 25 ° dH

eller 35°dH kan der ikke konstateres væsentlige inkrustati oner i vasketøjet efter vask 25 gange, hvorimod der ses en stigende 5 inkrustationsprocent ved anvendelse af et konventionelt vaskemiddel, når vandets hårdhed stiger. Tilsvarende ses det, at der ved anvendelse af vaskemidlet ifølge opfindelsen ikke er nogen forøget aflejringstendens, når vandets hårdhed stiger fra 20°dH til 35°dH, hvor man med det konventionelle vaskemid-10 del allerede ved 20°dH ser en væsentlig forøget kalkaflejringstendens, som stiger drastisk med endnu højere vandhårdheder .or 35 ° dH no significant incrustations can be found in the laundry after washing 25 times, whereas an increasing incrustation percentage is seen when using a conventional detergent as the hardness of the water increases. Similarly, it is seen that when using the detergent according to the invention there is no increased tendency to deposit when the hardness of the water increases from 20 ° dH to 35 ° dH, where with the conventional detergent a significant increase in lime deposition is already seen at 20 ° dH. , which rises drastically with even higher water hardnesses.

Forsøgene gennemførtes med DK 167363 B1 29 vand med hårdhedsgraderne 20, 25, 30 og 35edH, idet hårdheden bestod af ca. 75% calcium og 25% magnesium. De enkelte forsøg gennemførtes ved at opvarme 0,75 1 vand tilsat vaskemiddel under magnetomrøring med en dyppekoger til 95°C, hvor tem-5 peraturen blev holdt i 30 minutter. Forsøget blev gentaget 25 gange, hver gang med en ny portion af det vaskemiddelholdige vaskevand. Derefter blev den på dyppekogeren udfældede kalkmængde opløst i en 0,1M saltsyreopløsning, hvorefter indholdet af calcium og magnesium blev bestemt ved atomabsorptionsspek-10 trometri. De fremkomne resultater i form af den af lejrede mængde calcium + magnesium i mg fremgår af følgende tabel.an experiment to assess the tendency of limescale to heaters after 25 washes. The experiments were carried out with DK 167363 B1 29 water with hardness degrees 20, 25, 30 and 35edH, the hardness consisting of approx. 75% calcium and 25% magnesium. The individual experiments were carried out by heating 0.75 l of water with added detergent under magnetic stirring with a dip cooker to 95 ° C, where the temperature was kept for 30 minutes. The experiment was repeated 25 times, each time with a new portion of the detergent-containing wash water. Then, the amount of lime precipitated on the immersion kettle was dissolved in a 0.1 M hydrochloric acid solution, after which the content of calcium and magnesium was determined by atomic absorption spectrometry.
