Den foreliggende opfindelse angår et flydende storvaskemiddel, især egnet til vask af stærkt tilsmudsede tekstilstoffer under ma- q skinelle eller manuelle betingelser.The present invention relates to a liquid bulk detergent, particularly suitable for washing heavily soiled textiles under machine or manual conditions.
Man har længe erkendt, at builderholdige storvaskemidler i flydende form er bekvemmere at anvende end de sædvanlige produkter i O form af tørre pulvere. Nogle af fordelene ved flydende vaskemidler f “ er f.eks., at de ikke støver og klumper, og at de er lette at ορέ løse og anvende, især i de automatiske tilsætnings- og afmålings- ^ organer, som findes på flere moderne vaskemaskiner. Der er allerede blevet foreslået talrige vandige, flydende storvaskemidler, som 2 148239 beskrevet f.eks. i de britiske patentskrifter nr. 1.190.023 og 1.223.911 og USA patentskrifterne nr. 3.527.707, 3.591.508, 3.634.268, 3.707.503 og 3.702.621, men disse produkter er ikke blevet populære på grund af flere ulemper, som findes ved de hidtidige typer af flydende storvaskemidler. En af de vigtigste ugunstige faktorer er den forøgede pris for sådanne flydende storvaskemidler.It has long been recognized that builder-containing liquid detergents in liquid form are more convenient to use than the usual products in the form of dry powders. Some of the advantages of liquid detergents f are, for example, that they do not dust and lumps and that they are easy to dissolve and use, especially in the automatic addition and metering devices found on several modern washing machines . Numerous aqueous liquid bulk detergents have already been proposed, such as e.g. in British Patent Nos. 1,190,023 and 1,223,911 and United States Patent Nos. 3,527,707, 3,591,508, 3,634,268, 3,707,503 and 3,702,621, but these products have not become popular due to several disadvantages found in the previous types of liquid bulk detergents. One of the main adverse factors is the increased cost of such liquid bulk detergents.
For at være sammenlignelig med et konventionelt fast storvaskemiddel med hensyn til effektivitet skal et flydende vaskemiddel indeholde ikke blot en tilstrækkelig mængde builder-stof, men også en tilstrækkelig stor mængde renseaktivt materiale. På grund af natriumsaltes begrænsede opløselighed anvender man ofte de lettere opløselige, men dyrere kalium-, ammonium- eller triethanolaminsalte, indbefattende den mindre effektive, men lettere opløselige pyrophosphat-builder, til opnåelse de nødvendige surfactant- og builder-koncentrationer, og dog er resultaterne ikke sjældent et produkt, der indeholder utilstrækkeligt eller intet builder-stof, eller et utilstrækkeligt koncentreret produkt med utilfredsstillende storvaskeegenskaber. I mange tilfælde anvendes der også forholdsvis store mængder hydrotroper såsom alkalimetal- eller ammoniumtoluensulfaterne og xylensulfonater, men størstedelen af de kendte hydrotoper er dyre og bidrager desuden ikke til slutproduktets renseevne. Derved går der et værdifuldt spillerum tabt ved sammensætningen, hvilket ellers kunne være anvendt til hjælpestoffer, der yderligere ville forbedre renseevnen eller en anden ydelse.In order to be comparable to a conventional solid detergent for efficiency, a liquid detergent must contain not only a sufficient amount of builder, but also a sufficiently large amount of detergent. Due to the limited solubility of sodium salts, the slightly soluble but more expensive potassium, ammonium or triethanolamine salts, including the less efficient but more easily soluble pyrophosphate builder, are often used to obtain the required surfactant and builder concentrations, however the results are not infrequently a product containing insufficient or no builder fabric, or an insufficiently concentrated product with unsatisfactory large washing properties. In many cases, relatively large amounts of hydrotropes such as the alkali metal or ammonium toluene sulfates and xylene sulfonates are also used, but most of the known hydrotopes are expensive and furthermore do not contribute to the purity of the final product. Thereby, a valuable amount of leeway is lost in the composition, which could otherwise be used for auxiliaries that would further improve the cleaning performance or other performance.
Desuden er sammensætningen af et tilfredsstillende flydende storvaskemiddel bundet af visse viskositetsbegrænsninger. Desmere koncentreret produktet således er, jo højere vil viskositeten almindeligvis være, hvilket påvirker produktets håndteringsevne og ud-hældelighed i ugunstig retning. På den anden side udviser et for tyndt flydende produkt almindeligvis ringe ydeevne og er derfor uønskeligt. Desuden vil en sådan konsistens ikke tilfredsstille den almindelige forbrugers ønsker.In addition, the composition of a satisfactory liquid bulk detergent is bound by certain viscosity limitations. The more concentrated the product thus is, the higher the viscosity will generally be, which adversely affects the handling and pourability of the product. On the other hand, a too thin liquid product generally exhibits poor performance and is therefore undesirable. Moreover, such consistency will not satisfy the wishes of the ordinary consumer.
Et tilfredsstillende viskositetsområde for flydende vaskemidler til opnåelse af bekvem dosering og håndtering ligger mellem ca.A satisfactory viscosity range for liquid detergents to provide convenient dosage and handling is between approx.
3 146.299 100 cP og ca. 2.000 cP, men fortrinsvis mellem 200 og 1500 cP.3 146,299 100 cP and approx. 2,000 cP, but preferably between 200 and 1500 cP.
Gennem den foreliggende opfindelse tilvejebringes der et effektivt, vandigt, flydende storvaskemiddel, der indeholder tilstrækkelige mængder af overfladeaktive midler og builderstoffer og har en viskositet i det nævnte område, og som kan sammensættes billigt på basis af natrium som den primære kation og natriumtripoly-phosphat som hoved-builderstof .The present invention provides an effective aqueous liquid bulk detergent which contains sufficient amounts of surfactant and builder and has a viscosity in said range and which can be cheaply formulated on the basis of sodium as the primary cation and sodium tripolyphosphate as head-builder fabric.
Det er derfor formålet med den foreliggende opfindelse at tilvejebringe et effektivt storvaskemiddel i form af en udhældelig og stabil homogen væske af tilfredsstillende viskositet.It is, therefore, the object of the present invention to provide an effective large-scale detergent in the form of a pourable and stable homogeneous liquid of satisfactory viscosity.
Ovennævnte og andre fordele, der vil af det følgende, opnås ifølge opfindelsen ved, at der som basisvæske anvendes en vandig opløsning af et sæbeprodukt omfattende en blanding af (A) mindst én natriumsæbe af mættede Cg-C^-fedtsyrer og (B) mindst én natriumsæbe af mono- og/eller di-umættede C^g-C22“fedtsyrer, i hvilken blanding vægtforholdet mellem sæben (A) og sæben (B) ligger i området fra 9:1 til 1:9, fortrinsvis fra 4:1 til 1:4.The above and other advantages which will follow are obtained according to the invention by using as the base liquid an aqueous solution of a soap product comprising a mixture of (A) at least one sodium soap of saturated C 6 -C 3 fatty acids and (B) at least one sodium soap of mono- and / or di-unsaturated C ^ g-C22 “fatty acids, in which the mixture weight ratio of the soap (A) to the soap (B) ranges from 9: 1 to 1: 9, preferably from 4: 1 to 1: 4.
Flydende, vandige sæbeopløsninger, der har et højt sæbeindhold, men tillige eventuelt kan indeholde en builder såsom natrium-tripolyphosphat, er beskrevet i tilgængelig dansk patentansøgning nr. 1379/74. Der er heri tale om en flydende sæbeblanding hovedsagelig bestående af natriumsæber, men som kan indeholde mindre andele på under 20%, eller i hvert fald således at det ikke indvirker på sæbens opløselighed og dermed midlets stabilitet som flydende vandig fase. Sådanne andre bestanddele er f.eks. natriumtripolyphosphat-builder og eventuelt syntetisk detergent eller tensid.Liquid aqueous soap solutions which have a high soap content but may also optionally contain a builder such as sodium tripolyphosphate are disclosed in available Danish Patent Application No. 1379/74. This is a liquid soap mixture consisting mainly of sodium soaps, but which may contain smaller proportions of less than 20%, or at least such that it does not affect the solubility of the soap and thus the stability of the agent as a liquid aqueous phase. Such other constituents are e.g. sodium tripolyphosphate builder and optionally synthetic detergent or surfactant.
I modsætning hertil er den foreliggende opfindelse rettet på et flydende storvaskemiddel, der som sine væsentlige bestanddele omfatter fornødne andele af syntetisk vaskeaktivt materiale (tensid) og natriumtripolyphosphat, idet sæben kun er til stede i forholdsvis, små mængder, der i det væsentlige tjener som opløseliggørende hjælpemiddel.In contrast, the present invention is directed to a liquid bulk detergent comprising as its essential constituents the required proportions of synthetic detergent (surfactant) and sodium tripolyphosphate, the soap being present only in relatively small amounts which essentially serve as solubilizing agent. aid.
Det er herved konstateret, at med en flydende basis som ovenfor defineret opnås et forbedret medium til opløsning af aktive materialer, builderstoffer og andre bestanddele, hvorved man helt eller næsten helt undgår anvendelse af de sædvanlige hydrotroper eller opløseliggørende midler.It has been found hereby that with a liquid base as defined above, an improved medium is obtained for dissolving active materials, builder substances and other components, thereby avoiding, wholly or almost entirely, the use of the usual hydrotropes or solubilizers.

Det har også overraskende vist sig, at den flydende basis i midlet ifølge opfindelsen ganske let kan optage natriumsalte, således at man derved helt eller delvis kan undgå anvendelse af de dyre kalium-, ammonium eller triethanolaminsalte, uden at slutproduktets storvaskeegenskaber påvirkes.It has also surprisingly been found that the liquid base in the composition of the invention can readily absorb sodium salts, thereby avoiding the use of the expensive potassium, ammonium or triethanolamine salts in whole or in part, without affecting the large washing properties of the final product.
I overensstemmelse hermed angår opfindelsen et flydende storvaskemiddel omfattende natriumtripolyphosphat, et syntetisk tensid valgt blandt anioniske, ikke-ioniske, amphotere og zwitter-ioniske detergenter og blandinger deraf samt en sæbeblanding af (A) mindst én natriumsæbe af mættede Cg-C^-fedtsyrer og (B) mindst /en natriumsæbe af C-^gK^"1110110- og/eller di-umæt-tede fedtsyrer, hvor forholdet mellem sæben (A) og sæben (B) ligger i området mellem 1:9 og 9:1, idet mængden af eventuelt tilstedeværende andre fedtsyresæber ikke overstiger 20 vægtprocent af sæbeblandingen, hvilket middel er ejendommeligt ved, at det indeholder 10-25 vægtprocent syntetisk tensid, 5-30 vægtprocent natriumtripolyphosphat og 2-15 vægtprocent af sæbeblandingen, og at det flydende storvaskemiddel har en viskositet fra 200 til 1500 cP.Accordingly, the invention relates to a liquid bulk detergent comprising sodium tripolyphosphate, a synthetic surfactant selected from anionic, nonionic, amphoteric and zwitterionic detergents and mixtures thereof, and a soap mixture of (A) at least one sodium soap of saturated Cg-C3 fatty acids and (B) at least / one sodium soap of C- gKKK "1110110 and / or unsaturated fatty acids, wherein the ratio of the soap (A) to the soap (B) is in the range of 1: 9 to 9: 1, the amount of any other fatty acid soaps present not exceeding 20% by weight of the soap mixture, which is characterized in that it contains 10-25% by weight of synthetic surfactant, 5-30% by weight of sodium tripolyphosphate and 2-15% by weight of the liquid detergent. viscosity from 200 to 1500 cP.

Et foretrukket vaskeaktivt materiale til anvendelse i midlet ifølge opfindelsen omfatter imidlertid en blanding af anionogene og ikke-ionogene syntetiske detergenter, idet anvendelse af en sådan blanding i de flydende stor- 6 146299 vaskemiddel ifølge opfindelsen vil give god renseevne og tilfredsstillende skumopførsel, hvilket er typisk ønskede egenskaber til maskinvask.The aforementioned anionic, nonionic, ampholytic, and zwitterionic detergents may be used alone or mixed in the bulk detergent of the invention. However, a preferred detergent for use in the composition of the invention comprises a mixture of anionic and nonionic synthetic detergents, the use of such a composition in the liquid detergent of the invention will provide good cleaning performance and satisfactory foaming behavior, which is typically desired machine wash characteristics.

Foretrukne sæber af denne katagori er natriumoleat og sæbe afledet fra fedtsyrer indeholdende mere end 50 .vægts umættede C^g--fedtsyrer.Preferred soaps of this category are sodium oleate and soap derived from fatty acids containing more than 50% by weight of unsaturated C 1 -g fatty acids.
Det flydende storvaskemiddel ifølge opfindelsen indeholder mindst 5 væqt% natriumtripolyphosphat, og det kan, om ønsket, yderligere indeholde et hvilket som helst andet af de forskellige typer af kendte builderstoffer, indbefattende organiske builderstoffer såsom natrium- eller kaliumpyrophosphat og natrium-nitrilotriacetat, samt sekvestreringsmidler, f.eks. natriumethylen-diamintetraacetat, og andre hjælpestoffer, der er almindeligt anvendt i vaskemiddelsammensætninger. Eksempler på sådanne andre hjælpestoffer er alkalimetalsilicater, anti-genafsætningsmidler, f.eks. natrium-carboxymethylcellulose og polyvinylpyrrolidon, optiske og kemiske blegemidler, parfumer, antibakterielle midler, farvemidler, enzymer, skum-forbedrere eller -undertrykkere, hydrotroper og dispergerings-midler. Af grunde, der ikke nødvendigvis er essentielle for opfindelsen, kan der også anvendes andre nyttige hjælpestoffer såsom de forskellige kendte polymer/copolymer-forbindelser, f.eks. copolymerene af maleinsyreanhydrid og ethylen- eller vinylmethylether.The liquid bulk detergent of the invention contains at least 5 wt.% Sodium tripolyphosphate and may, if desired, further contain any of the various types of known builders, including organic builders such as sodium or potassium pyrophosphate and sodium nitrilotriacetate, as well as sequestering agents. eg. sodium ethylene diamine tetraacetate, and other excipients commonly used in detergent compositions.

Desuden kan der tolereres tilstedeværelse af små mængder af andre fedtsyresæber, selvom dette er uønsket. Generelt må mængden • af tilstedeværende andre fedtsyresæber ikke være større end 20 vægt% af det obligatoriske sæbeprodukt.In addition, the presence of small amounts of other fatty acid soaps may be tolerated, although this is undesirable. In general, the amount of • other fatty acid soaps present must not exceed 20% by weight of the mandatory soap product.
Gennem opfindelsen tilvejebringes et stabilt flydende vaskemiddel, der indeholder en tilstrækkelig mængde vaskeaktive materialer såvel som tilstrækkelige mængder af builderstoffer, og som dog har en viskositet, der ligger indenfor det område fra ca. 200 cP til ca.The invention provides a stable liquid detergent which contains a sufficient amount of detergent-active materials as well as sufficient amounts of builder substances, yet having a viscosity within the range of from about 10 to about 10. 200 cP to approx.
1500 cP, der er accepteret til bekvem håndtering og dosering.1500 cP accepted for convenient handling and dosing.
En særlig fordel ved midlet ifølge opfindelsen er, at det deri anvendte sæbeprodukt, der virker som opløseliggører for de forskellige bestanddele, i sig selv udgør et renseaktivt materiale og derved bidrager til det flydende middels renseevne.A particular advantage of the agent according to the invention is that the soap product used therein, which acts as a solubilizer for the various components, is itself a cleaning active material and thereby contributes to the cleaning agent of the liquid agent.
Selvom andre builderstoffer, indbefattende kaliumtripolyphos-phat, kan inkorporeres i de flydende vaskemidler ifølge opfindelsen foruden natriumtripolyphosphat, er det essentielle for opfindelsen, at der som hoved-builderstof i produktet anvendes natriumtripolyphosphat .Although other builders, including potassium tripolyphosphate, can be incorporated into the liquid detergents of the invention in addition to sodium tripolyphosphate, it is essential for the invention that as the main builder in the product, sodium tripolyphosphate be used.
Et overraskende træk ved den foreliggende opfindelse er, at der herigennem kan sammensættes et flydende vaskemiddel, der viser bemærkelsesværdig god stabilitet i kulden ved temperaturer så lave som -5°C, hvilket vil sige, at væsken ikke vil vise nogen udskillelse eller størkning og dog bibeholder sin viskositet indenfor det ovenfor e angivne område, hvilket er en yderligere fordel.A surprising feature of the present invention is that hereby a liquid detergent which exhibits remarkably good stability in the cold at temperatures as low as -5 ° C can be assembled, which means that the liquid will show no separation or solidification and yet maintains its viscosity within the range indicated above, which is a further advantage.
