Abstract
Description
Oppfinnelsen vedrører høyt-skummende flytende vaskemiddelblandinger egnet for bruk til vasking av tøy, i shampooer og fremfor alt i manulle oppvaskoperasjoner både i hardt og bløtt vann. The invention relates to high-foaming liquid detergent mixtures suitable for use in washing clothes, in shampoos and above all in manual dishwashing operations in both hard and soft water.
Når det her snakkes om "oppvask", mener man vask av redskaper som er involvert i fremstilling eller fortæring av mat, som det kan være nødvendig å vaske fri for matvarepartikler og andre matrester, fett, proteiner, stivelser, gummier, farvestoffer, When we talk about "dishwashing" here, we mean the washing of utensils that are involved in the preparation or consumption of food, which it may be necessary to wash free of food particles and other food residues, fats, proteins, starches, gums, dyes,
oljer og brente organiske rester.oils and burnt organic residues.
Britisk patent nr. 1.429.637 beskriver oppvaskmiddel-blandinger for manuell bruk som som vaskeaktivt materiale inneholder et vannløselig salt av en di-(C7-Cg)-alkylester av sulforavsyre, i kombinasjon med et alkylsulfat eller et alkyletersulfat. British Patent No. 1,429,637 describes dishwashing detergent mixtures for manual use which contain as detergent active material a water-soluble salt of a di-(C7-C8) alkyl ester of sulforavic acid, in combination with an alkyl sulfate or an alkyl ether sulfate.
Britiske patenter nr. 2.108.520, 2.104.913 og 2.105.325 British Patent Nos. 2,108,520, 2,104,913 and 2,105,325
samt europeiske patenter nr. 71413 og 71414 beskriver høyt-skummende vaskemiddelblandinger basert på visse dialkylsulfosuksinater, spesielt slike som har C,- og CQ-kjeder. as well as European Patent Nos. 71413 and 71414 describe high-foaming detergent compositions based on certain dialkyl sulfosuccinates, especially those having C 1 and C 2 chains.

Britisk patent nr. 1.164.854 beskriver innlemmelse av 0,5 -British Patent No. 1,164,854 describes the incorporation of 0.5 -
10 vekt% av et vannløselig uorganisk magnesiumsalt i vandige, flytende vaskemiddelblandinger basert på et alkyl- eller aryl-sulfonat i tilknytning til et alkyletersulfat eller et ikke-ionisk vaskemiddel. 10% by weight of a water-soluble inorganic magnesium salt in aqueous, liquid detergent mixtures based on an alkyl or aryl sulphonate in association with an alkyl ether sulphate or a non-ionic detergent.
Foreliggende oppfinnelse er basert på den observasjon at nærvær av små mengder av magnesium-ioner, som stammer fra en tilsatt elektrolytt, i flytende vaskemiddelblandinger basert på dialkylsulfosuksinater gir både fordeler når det gjelder ytelse og sammensetning. The present invention is based on the observation that the presence of small amounts of magnesium ions, originating from an added electrolyte, in liquid detergent mixtures based on dialkylsulfosuccinates provides both advantages in terms of performance and composition.
Oppfinnelsen tilveiebringer følgelig en skummende, flytende vaskemiddelblanding i form av en klar, stabil, vandig løsning som inneholder 2-60 vekt% aktivt vaskemiddel som omfatter minst 2 vekt%, fortrinnsvis minst 5 vekt%, basert på hele blandingen, Accordingly, the invention provides a foaming, liquid detergent mixture in the form of a clear, stable, aqueous solution containing 2-60% by weight active detergent comprising at least 2% by weight, preferably at least 5% by weight, based on the whole mixture,
av et vannløselig salt av en dialkylsulforavsyre, idet blandingen inneholder minst 0,02 vekt% magnesium-ioner som stammer fra en tilsatt elektrolytt. of a water-soluble salt of a dialkylsulfuric acid, the mixture containing at least 0.02% by weight of magnesium ions originating from an added electrolyte.
I henhold til oppfinnelsen kommer magnesium-ioner inn i produktet som del av et tilsatt vannløselig magnesiumsalt, f.eks. magnesiumsulfat, -klorid eller -toluen- eller -xylensulfonat. According to the invention, magnesium ions enter the product as part of an added water-soluble magnesium salt, e.g. magnesium sulphate, chloride or toluene or xylene sulphonate.
Nærværet av magnesium-ioner har vist seg å gi forbedret skummeytelse i svært bløtt vann. Denne effekt er allerede blitt observert hos vaskeaktive materialer forskjellig fra dialkyl-sulf osuksinater , f.eks. alkylbenzensulfonater, men tilsetning av magnesiumsalter er generelt skadelig for produktets stabilitet ved lav temperatur, da det bevirker at både tåke- og klar-punktet stiger. Det skal forklares at tåkepunktet er den temperatur ved hvilken klarhet hos blandingen går tapt etterhvert som den utvendige temperatur senkes; klarpunktet er den temperatur ved hvilken en klar løsning gjenvinnes etterhvert som den utvendige temperatur heves igjen. The presence of magnesium ions has been shown to provide improved foaming performance in very soft water. This effect has already been observed with detergent-active materials other than dialkyl sulfosuccinates, e.g. alkylbenzene sulphonates, but the addition of magnesium salts is generally detrimental to the stability of the product at low temperature, as it causes both the cloud and clear points to rise. It should be explained that the cloud point is the temperature at which the clarity of the mixture is lost as the external temperature is lowered; the clear point is the temperature at which a clear solution is recovered as the external temperature is raised again.
Overraskende er det funnet at tilsetning av små mengder av magnesiumsalter til flytende produkter basert på dialkylsulfosuksinater faktisk bevirker senkning av klarpunktet og i blandinger av relativt lav konsentrasjon også øker viskositeten. Surprisingly, it has been found that the addition of small amounts of magnesium salts to liquid products based on dialkyl sulphosuccinates actually causes a lowering of the clear point and, in mixtures of relatively low concentration, also increases the viscosity.
Mengden av tilsatt magnesiumsalt er i området fra 0,02 til 0,24 vekt% magnesium-ioner. Det optimale tilsetningsnivå innen disse grenser for enhver spesiell sammensetning vil være avhengig av den totale aktive vaskemiddelkonsentrasjon, det totale nivå og typen av elektrolytt som er til stede og hydrotropnivået, og kan lett bestemmes eksperimentelt av en fagmann på området. The amount of magnesium salt added is in the range from 0.02 to 0.24% by weight of magnesium ions. The optimum addition level within these limits for any particular composition will depend on the total active detergent concentration, the total level and type of electrolyte present and the hydrotrope level, and can be readily determined experimentally by one skilled in the art.
Magnesium-ionene tilsettes i blandingene i henhold til oppfinnelsen i form av vannløselige magnesiumsalter som er elektro-lytter. De foretrukne salter er magnesiumsulfat og magnesiumklorid. For magnesiumklorid-heksahydrat tilsvarer de grenser som er gitt ovenfor 0,17-2,02 vekt%; for magnesiumsulfat-heptahydrat tilsvarer de grenser som er gitt ovenfor 0,21-2,46 vekt%. Følgelig er den mengde av tilsatt magnesiumsalt som er til stede i blandingene i henhold til oppfinnelsen fortrinnsvis 0,15-2,50 vekt%, helst 0,50-1,50 vekt%. The magnesium ions are added to the mixtures according to the invention in the form of water-soluble magnesium salts which are electrolytes. The preferred salts are magnesium sulfate and magnesium chloride. For magnesium chloride hexahydrate, the limits given above correspond to 0.17-2.02% by weight; for magnesium sulfate heptahydrate the limits given above correspond to 0.21-2.46% by weight. Accordingly, the amount of added magnesium salt present in the compositions according to the invention is preferably 0.15-2.50% by weight, preferably 0.50-1.50% by weight.
Det totale aktive vaskemiddelnivå i blandingene i henholdThe total active detergent level in the mixtures according to
til oppfinnelsen kan variere fra 2 til 60 vekt%, fortrinnsvis fra 5 til 40 vekt%. Tilsetning av magnesiumsalter i overens-stemmelse med oppfinnelsen er spesielt velgjørende ved totalt aktive vaskemiddelnivåer på 30 vekt% og lavere. Ved den nedre ende av konsentrasjonsområdet, 20% og under det, observeres det ytterligere gode med viskositetsøkning. Således demper foreliggende oppfinnelse problemet med lave viskositeter som kan to the invention can vary from 2 to 60% by weight, preferably from 5 to 40% by weight. Addition of magnesium salts in accordance with the invention is particularly beneficial at total active detergent levels of 30% by weight and lower. At the lower end of the concentration range, 20% and below, the further benefit of viscosity increase is observed. Thus the present invention mitigates the problem of low viscosities which can
oppstå hos lav-aktive vaskemiddelblandinger basert på dialkyl-sulf osuksinat. occur with low-active detergent mixtures based on dialkyl sulfosuccinate.
Dialkylsulfosuksinatet, som er et essensielt vaskeaktivt materiale i produktet i henhold til oppfinnelsen, kan enten være symmetrisk (begge alkylgrupper er like) eller usymmetrisk. The dialkyl sulfosuccinate, which is an essential detergent active material in the product according to the invention, can be either symmetrical (both alkyl groups are the same) or unsymmetrical.
Om ønskes, kan det være sammensatt av en blanding av materialer med forskjellige kjedelengder, hvor de enkelte dialkylsulfosuksinater selv enten kan være symmetriske eller usymmetriske. If desired, it can be composed of a mixture of materials with different chain lengths, where the individual dialkyl sulphosuccinates themselves can either be symmetrical or unsymmetrical.
De vaskeaktive dialkylsulfosuksinater er forbindelser av formel I: The detergent-active dialkyl sulfosuccinates are compounds of formula I:
hvor hver av R1og R2, som kan være like eller forskjellige, representerer en rettkjedet eller forgrenet alkylgruppe som har 3-12 karbonatomer, fortrinnsvis 4-10 karbonatomer og helst 6-8 karbonatomer, og X.^representerer et solubiliserende kation, d.v.s. ethvert kation som gir et salt av formel I som er til-strekkelig til å være vaskeaktivt. I foreliggende oppfinnelses-tekstsammenheng vil det solubiliserende kation generelt være enverdig, f.eks. alkalimetall, spesielt natrium; ammonium; eller substituert ammonium, f.eks. etanolamin. where each of R 1 and R 2 , which may be the same or different, represents a straight-chain or branched alkyl group having 3-12 carbon atoms, preferably 4-10 carbon atoms and preferably 6-8 carbon atoms, and X represents a solubilizing cation, i.e. any cation which gives a salt of formula I which is sufficient to be detergent active. In the context of the present invention text, the solubilizing cation will generally be monovalent, e.g. alkali metal, especially sodium; ammonium; or substituted ammonium, e.g. ethanolamine.
Alkylgruppene R, og R2i dialkylsulfosuksinatet er fortrinnsvis rettkjedet eller (i blandinger) overveiende rettkjedet. The alkyl groups R, and R2 in the dialkyl sulphosuccinate are preferably straight chain or (in mixtures) predominantly straight chain.
Blant dialkylsulfosuksinater som med fordel kan anvendes i produktet i henhold til oppfinnelsen er de Cg/Cg-usymmetriske materialer som er beskrevet og beskyttet ved britisk patent nr. 2,105.325; de dioktylsulfosuksinat/diheksylsulfosuksinat-blandinger som er beskrevet og beskyttet ved britisk patent nr. 2,104.913; og de blandinger av symmetriske og usymmetriske dialkylsulfosuksinater som er beskrevet og beskyttet ved britisk patent nr. 2.108.520. Among the dialkyl sulphosuccinates which can be advantageously used in the product according to the invention are the Cg/Cg unsymmetrical materials which are described and protected by British patent no. 2,105,325; the dioctyl sulfosuccinate/dihexyl sulfosuccinate mixtures described and protected by British Patent No. 2,104,913; and the mixtures of symmetrical and unsymmetrical dialkyl sulfosuccinates described and protected by British Patent No. 2,108,520.
Produktet i henhold til oppfinnelsen kan naturligvis med fordel inneholde andre vaskeaktive midler i tillegg til dialkyl-sulf osuksinatet, forutsatt at den totale blanding inneholder minst 2 vekt%, fortrinnsvis minst 5 vekt%, av dialkylsulfosuksinat(er). Blandingen kan f.eks. inkludere et eller flere av de vaskemidler av sulfonat-type som konvensjonelt anvendes som hoved-vaskeaktivt middel i flytende blandinger, f.eks. alkylbenzensulfonater (spesielt Cg-C^-lineære alkylbenzensulfonater), sekundære alkansulfonater, a-olefin-sulfonater, alkylglyceryletersulfonater, samt fettsyreestersulfonater. Naturligvis er dialkylsulfosuksinater selv vaskemidler av sulfonat-type. Hvis slike ytterligere materialer av sulfonat-type er til stede, dominerer det totale sulfonat fortrinnsvis i den vaskeaktive blanding i produktet i henhold til oppfinnelsen. Hvis ingen slike ytterligere materialer av sulfonat-type er til stede, dominerer fortrinnsvis sulfosuksinatet alene. The product according to the invention can of course advantageously contain other detergents in addition to the dialkyl sulfosuccinate, provided that the total mixture contains at least 2% by weight, preferably at least 5% by weight, of dialkyl sulfosuccinate(s). The mixture can e.g. include one or more of the sulfonate-type detergents that are conventionally used as the main detergent active agent in liquid mixtures, e.g. alkylbenzenesulfonates (especially Cg-C^-linear alkylbenzenesulfonates), secondary alkane sulfonates, α-olefin sulfonates, alkyl glyceryl ether sulfonates, as well as fatty acid ester sulfonates. Naturally, dialkyl sulfosuccinates are themselves sulfonate-type detergents. If such additional sulfonate-type materials are present, the total sulfonate preferably predominates in the detergent-active mixture in the product according to the invention. If no such additional sulfonate-type materials are present, preferably the sulfosuccinate alone predominates.
Blant de ytterligere vaskemidler av sulfonat-type som kan være til stede, foretrekkes spesielt alkylbenzensulfonater og sekundære alkansulfonater. Forholdet mellom dialkylsulfosuksinat og alkylbenzensulfonat eller sekundært alkansulfonat er fortrinnsvis i området fra 4:1 til 0,1:1, helst fra 2,5:1 til 1:1. Among the additional sulfonate-type detergents that may be present, alkylbenzene sulfonates and secondary alkane sulfonates are particularly preferred. The ratio of dialkylsulfosuccinate to alkylbenzenesulfonate or secondary alkanesulfonate is preferably in the range from 4:1 to 0.1:1, preferably from 2.5:1 to 1:1.

Det uetoksylerte materiale er naturligvis alkylsulfat. Om ønsket kan ytterligere alkylsulfat være blandet med alkyletersulfatet, slik at det forekommer en blanding hvor etoksyleringsfordelingen er mer vektgivende mot lavere verdier. In any given alkyl ether sulfate, a range of variously ethoxylated materials, as well as some unethoxylated material, will be present, and the value of n represents an average. The unethoxylated material is naturally alkyl sulfate. If desired, additional alkyl sulfate can be mixed with the alkyl ether sulfate, so that a mixture occurs where the ethoxylation distribution is more weighted towards lower values.
Det foretrekkes spesielt å anvende alkyletersulfater som inneholder mindre enn 20 vekt% materiale med kjedelengde og høyere, som beskrevet og krevet beskyttet i vår samtidige søknad av samme dato, som krever prioritet fra britisk søknad nr. 82 32686 innlevert 16. nov. 1982.

Vektforholdet mellom alkyletersulfat og ikke-ionisk vaskemiddel er fortrinnsvis minst 1:1 og mer å foretrekke i området fra 1,5:1 til 3:1, spesielt 2:1. Et spesielt foretrukket ikke-ionisk vaskemiddel er "Dobanol" ® 91-8 fra Shell, hvor R4 er Cg-<C>ll(°verveien<^e rettkjedet) og m er 8. The weight ratio between alkyl ether sulfate and nonionic detergent is preferably at least 1:1 and more preferably in the range from 1.5:1 to 3:1, especially 2:1.

Incorporation of this material, at a level that does not exceed
30% i vekt av den aktive vaskemiddelblanding, gir både ytelse- og sammensetningsfordeler. Vår samtidige søknad av samme dato, som krever prioritet fra britisk søknad nr. 82 32688, innlevert 16. nov. 1982, beskriver og krever beskyttelse for flytende vaskemiddelblandinger som inneholder et dialkylsulfosuksinat, et alkyletersulfat og/eller et ikke-ionisk vaskemiddel, samt et C^Q-C^g-karboksylsyre-di-(C2~C2)-alkanolamid, idet sistnevnte komponent er til stede i en mengde som ikke overstiger 30% i vekt av det totale aktive vaskemiddel som er til stede. 30% by weight of the active detergent mixture provides both performance and composition advantages. Our concurrent application of the same date, which claims priority from British Application No. 82 32688, filed Nov. 16 1982, describes and claims protection for liquid detergent compositions containing a dialkyl sulfosuccinate, an alkyl ether sulfate and/or a nonionic detergent, and a C^Q-C^g-carboxylic acid di-(C2~C2)-alkanolamide, the latter component being present in an amount not exceeding 30% by weight of the total active detergent present.
Såvel som aktivt vaskemiddel, magnesium-ioner og vann vil blandingen i henhold til oppfinnelsen generelt trenge å inneholde en eller flere hydrotroper. Disse er materialer som er til stede i en blanding for å regulere løselighet, viskositet, klarhet og stabilitet, men som selv ikke bidrar aktivt til produktets ytelse. Eksempler på hydrotroper inkluderer lavere alifatiske alkoholer, spesielt etanol; urinstoff; lavere alkylbenzensulfonater, f.eks. natriumtoluen- og -xylensulfonater; og kombinasjoner av disse. Hydrotroper er kostbare og tar opp plass i en blanding uten å bidra til dens ytelse, og det er derfor ønskelig å anvende så As well as active detergent, magnesium ions and water, the mixture according to the invention will generally need to contain one or more hydrotropes. These are materials that are present in a mixture to regulate solubility, viscosity, clarity and stability, but which themselves do not actively contribute to the product's performance. Examples of hydrotropes include lower aliphatic alcohols, especially ethanol; urea; lower alkylbenzene sulphonates, e.g. sodium toluene and xylene sulfonates; and combinations of these. Hydrotropes are expensive and take up space in a mixture without contributing to its performance, and it is therefore desirable to use such
små mengder av dem som mulig.small amounts of them as possible.
Blandingene i henhold til oppfinnelsen kan også inneholde de vanlige små ingredienser, f.eks. parfyme, farve, konserverings-midler og germicider. The mixtures according to the invention can also contain the usual small ingredients, e.g. perfume, colouring, preservatives and germicides.
De flytende vaskemiddelblandinger i henhold til oppfinnelsen, som inneholder 2-60 vekt% aktivt vaskemiddel i klar, stabil, vandig løsning, kan anvendes for alle normale vaskeformål hvor det er fordelaktig med skumming, f.eks. for tøyvaskeprodukter, for rengjøringspreparater for generell husholdningsbruk og industri-bruk, teppeshampoo, bilvaskeprodukter, vaskeprodukter for personlig hygiene, shampoo, skumbadprodukter, og, fremfor alt, for manuell oppvask The liquid detergent mixtures according to the invention, which contain 2-60% by weight of active detergent in a clear, stable, aqueous solution, can be used for all normal washing purposes where foaming is advantageous, e.g. for laundry products, for cleaning preparations for general household and industrial use, carpet shampoo, car wash products, washing products for personal hygiene, shampoo, foam bath products, and, above all, for manual dishwashing

Det anvendte dialkylsulfosuksinat var en statistisk blanding (molforhold 1:2:1) av di-n-oktylsulfosuksinat, n-heksyl-n-oktylsulfosuksinat og di-n-heksylsulfosuksinat, fremstilt av en 1:1 blanding av n-heksanol og n-oktanol ved den metode som er beskrevet i eksempel 1 i britisk patentskrift nr. 2.108.520. Dette materiale inneholdt 2,5% natriumsulfat i en 40% løsning, slik at natrium-sulfatnivået i blandingene var 1 vekt%. The dialkylsulfosuccinate used was a statistical mixture (molar ratio 1:2:1) of di-n-octylsulfosuccinate, n-hexyl-n-octylsulfosuccinate and di-n-hexylsulfosuccinate, prepared from a 1:1 mixture of n-hexanol and n- octanol by the method described in example 1 in British patent document no. 2,108,520. This material contained 2.5% sodium sulphate in a 40% solution, so that the sodium sulphate level in the mixtures was 1% by weight.
Det anvendte etersulfat var "Dobanol" 23-2S fra ShellThe ether sulfate used was "Dobanol" 23-2S from Shell
(50% C12, 50% C13; n = 2; natriumsalt).(50% C12, 50% C13; n = 2; sodium salt).
Magnesiumet ble tilsatt i form av magnesiumklorid-heksahydrat. Resultatene var som følger: The magnesium was added in the form of magnesium chloride hexahydrate. The results were as follows:
Selv om tåkepunktet steg litt med økende magnesiumion-nivå, var klarpunktet betydelig senket ved 0,5% MgClo.6Ho0, (0,06% Although the cloud point rose slightly with increasing magnesium ion level, the clear point was significantly lowered at 0.5% MgClo.6Ho0, (0.06%

Eksemplene 1 og 2 ble gjentatt med en dialkylsulfosuksinat-prøve som inneholdt et lavere nivå (1%) av natriumsulfat, slik at det totale nivå av nevnte materiale i blandingen bare var 0,4 vekt%. Ved dette lavere elektrolytt-nivå kunne urinstoff-innholdet bli satt ned til 11%. Examples 1 and 2 were repeated with a dialkyl sulfosuccinate sample containing a lower level (1%) of sodium sulfate, so that the total level of said material in the mixture was only 0.4% by weight. At this lower electrolyte level, the urea content could be reduced to 11%.
Resultatene var som følger:The results were as follows:
Man vil se at ved dette lavere elektrolytt-nivå ble det krevet en større mengde av magnesiumklorid-heksahydrat for å bevirke signifikant senkning av klarpunktet. It will be seen that at this lower electrolyte level, a larger amount of magnesium chloride hexahydrate was required to effect a significant lowering of the clear point.
Eksempler 5&6Examples 5&6
Eksemplene 3 og 4 ble gjentatt med "Dobanol" 23-2A (det tilsvarende ammoniumsalt) istedenfor "Dobanol" 23-2S. Examples 3 and 4 were repeated with "Dobanol" 23-2A (the corresponding ammonium salt) in place of "Dobanol" 23-2S.
Resultatene var som følger:The results were as follows:
Som man vil se, senket anvendelse av ammoniumsaltet av etersulfatet istedenfor natriumsaltet, ved det samme totale elektrolytt-nivå, det nivå av MgCl2.6H20 som ble krevet for å gi en klarpunkt-senkning fra 1,0 til 0,5%, mens nivået på 1,0% nå var høyere enn det optimale. As will be seen, using the ammonium salt of the ether sulfate instead of the sodium salt, at the same total electrolyte level, lowered the level of MgCl2.6H20 required to produce a clear point reduction from 1.0 to 0.5%, while the level of 1.0% now was higher than the optimum.

Resultatene var som følger:The results were as follows:
Man vil se at et magnesiumklorid-nivå på 0,5% var util-strekkelig for å senke klarpunktet, men det høyere nivå på 1,0% var effektivt. It will be seen that a magnesium chloride level of 0.5% was insufficient to lower the clear point, but the higher level of 1.0% was effective.

Dette eksempel viser forbedringen i skumme-ytelse i bløtt vann oppnådd ved tilsetning av magnesiumklorid-heksahydrat til en dialkylsulfosuksinat/etersulfat-blanding. This example shows the improvement in foaming performance in soft water obtained by adding magnesium chloride hexahydrate to a dialkyl sulfosuccinate/ether sulfate mixture.
Sammenligningen ble utført ved hjelp av en tallerkenvaske-test i vann av 1°H (fransk hardhet). The comparison was carried out using a dishwashing test in water of 1°H (French hardness).
I testen ble tallerkner tilsmusset med en standard blanding av stivelse, fett og fettsyre og vasket på standard måte med 5 liter testløsning (total konsentrasjon 1 g/liter ved 45°C) In the test, plates were soiled with a standard mixture of starch, fat and fatty acid and washed in the standard way with 5 liters of test solution (total concentration 1 g/litre at 45°C)

Antall tallerkner som var vasket før dette vilkårlig fastsatte endepunkt var nådd, ble regnet som indikator på oppvask- og skumme-ytelse. in a dish, until only a third of the surface of the solution in the dish was covered with foam. The number of plates that were washed before this arbitrarily set end point was reached was counted as an indicator of washing and foaming performance.
Det dialkylsulfosuksinat som ble anvendt var den C^/Cg-statistiske blanding fra eksempel 2, ved en konsentrasjon av 16 vekt%, og etersulfatet var "Dobanol" 23-2S, ved en konsentrasjon av 8 vekt%. The dialkyl sulfosuccinate used was the C₁/Cg statistical mixture from Example 2, at a concentration of 16% by weight, and the ether sulfate was "Dobanol" 23-2S, at a concentration of 8% by weight.
Denne blanding uten tilsatt magnesiumklorid-heksahydrat vasket 23 tallerkner, og med tilsetning av 1,0 vekt% magnesiumklorid-heksahydrat vasket den 27 tallerkner. This mixture without added magnesium chloride hexahydrate washed 23 plates, and with the addition of 1.0% by weight of magnesium chloride hexahydrate it washed 27 plates.

Dette forsøk viser effekten av tilsetning av et magnesiumsalt til en blanding med relativt lav konsentrasjon (16%) inneholdende et fettsyredietanolamid i tillegg til et dialkylsulfosuksinat og et alkyletersulfat. Dialkylsulfosuksinatet var den Cg/Cg-blanding som ble anvendt i eksemplene 1 og 2, inneholdende 2,5 vekt% elektrolytt (natriumsulfat) i en 40% løsning. Alkyletersulfatet var "Dobanol" 23-3A, og fettsyredietanolamidet var "Empilan"<®>CDE fra Albright&Wilson, et kokosnøtt-dietanolamid. This experiment shows the effect of adding a magnesium salt to a mixture of relatively low concentration (16%) containing a fatty acid diethanolamide in addition to a dialkyl sulfosuccinate and an alkyl ether sulfate. The dialkyl sulfosuccinate was the Cg/Cg mixture used in Examples 1 and 2, containing 2.5% by weight of electrolyte (sodium sulfate) in a 40% solution. The alkyl ether sulfate was "Dobanol" 23-3A, and the fatty acid diethanolamide was "Empilan"<®>CDE from Albright&Wilson, a coconut diethanolamide.
Resultatene er vist i følgende tabell. Alle tre nivåer av magnesiumsalt var effektive med hensyn til å senke klar- og tåkepunktene, og alle tre nivåer hevet viskositeten, idet nivået på 1,0% var optimalt i denne siste henseende. The results are shown in the following table. All three levels of magnesium salt were effective in lowering the clear and cloud points, and all three levels raised the viscosity, with the 1.0% level being optimal in this latter respect.

I dette tilfelle ble et magnesiumsalt-nivå på 0,5% funnet å gi optimale fordeler. The procedure from Examples 10-12 was repeated with a mixture which had the same total active detergent level (16%), but which contained a larger proportion (10%) of the dialkyl sulfosuccinate.

Comparative mixture H already had excellent low-temperature stability. Addition of 0.5% magnesium chloride increased the viscosity without damage to the cloud point. The higher level of magnesium chloride (1.0%) further improved viscosity to a slight, but negligible, detriment to low-temperature stability.
