Definitions

• the invention relates to aqueous surfactant preparations which are at rest in the form of two or more segregated, liquid, aqueous phases which are temporarily dispersible in one another by movement.
• EP 0116 442 A1 describes a shampoo which consists of two segregated aqueous phases and whose specifically heavier, lower phase has a content of at least 6% by weight of dissolved sodium hexametaphosphate. Such a high content of condensed phosphates is neither advantageous in terms of application technology nor ecologically desirable.
• JP 62 263 297 AI cosmetic cleaning agents which have two segregated, liquid, aqueous phases and which are characterized by a content of surfactants and water-soluble polymers.
• the cleaning agents described there take a relatively long time (several hours) until they separate again in the idle state after mixing.
• Hibernation can be achieved by a content of water-soluble, mono- or polyhydric alcohols.
• the invention therefore relates to aqueous preparations which are present in the quiescent state in the form of two or more unmixed aqueous phases which are at times dispersible in motion with one another with at least one dissolved surface-active compound and at least one dissolved polymer compound which, in order to accelerate the phase separation in the quiescent state, contain at least one water-soluble one - or polyhydric alcohol with 2 - 9 carbon atoms.
• the dissolved surface-active compounds contained in the preparation according to the invention can be ionogenic or nonionic compounds, the decisive factor being that they have a preferably linear lipid group with 8-22 C atoms and at least one water-solubilizing polyol or polyether group or a water-solubilizing salt-forming group, e.g. contain a carboxyl, sulfonate or sulfate ester group or both or an optionally quaternary ammonium group or ampholytic aminocarboxylate or aminosulfonate group or a betaine grouping, preferably at one end of the linear lipid group.
• Suitable cosmetic cleaning agents are preferably those preparations which contain, as surface-active compounds, high-foaming anionic surfactants, ie preferably those with anionic sulfonate or sulfate ester groups in the form of their alkali metal, magnesium or ammonium salts.
• Such preferred surfactants are especially the alkyl polyglycol ether sulfate salts or the alkyl polyglycol ether sulfosuccinate salts, e.g. as sodium salts meet the general formula I or II:
• R and R are preferably a linear alkyl group with 8-22, preferably with
• n is a number from 1-6, preferably from 2-4.
• anionic surfactants are e.g. Soaps, N-acylamino acid salts,
• Alkyl phosphate salts alkyl polyglycol ether carboxylate salts, alkyl sulfate alkanolamine salts,
• Alkyl sulfonate salts Alkyl sulfonate salts, ⁇ -olefin sulfonate salts, acyl isethionate salts and acyl taurine salts.
• amphoteric and / or zwitterionic surfactants e.g. Cocoamphoglycinate or Cocoamidopropyl-dimethyl-ammonio-glycinate and betaine surfactants are included.

• Fatty acids Fatty acids, fatty alcohols, fatty acid monoglycerides, fatty acid alkanolamides, fatty acid sorbitan esters, alkylphenols, methyl glucoside fatty acid esters and other polar lipids as well
• Alkyl glucosides and their ethylene oxide adducts can be contained as surface-active substances.
• the total amount of surface-active substances can be 5 to 40% by weight, but an amount of 5 to 20% by weight is preferred, since otherwise the rapid separation of the phases can no longer be guaranteed.
• Suitable polymer compounds are all natural or synthetic high-molecular substances with recurring structural elements which are soluble in water or aqueous surfactant solutions at 20 ° C. in amounts of at least 1% by weight.
• Natural polymers are understood to mean water-soluble proteins or water-soluble polysaccharides or the water-soluble derivatives of water-insoluble proteins or polysaccharides.
• Suitable natural polymers are, for example, albumins, gelatin, glycosaminoglycans (hyaluronic acid), chitosans, starch, guar, cellulose ethers, for example methyl celluloses or hydroxyethyl celluloses, carboxymethyl celluloses and cationic cellulose derivatives, for example starch, guar or cellulose ethers modified with epoxypropyl trimethylammoinum chloride.

• Polymer compounds selected from polypropylene glycols with molecular weights of more than 1000 D, hydroxyethyl celluloses, xanthan gum, dextran, sodium hyaluronate and cationic cellulose ethers are preferably suitable for the preparation of the preparations according to the invention.
• the amounts of polymer compounds required for segregation depend on the type and molecular weight of the polymer compound, it generally applies that the higher the molecular weight of the polymer compound, the lower the amounts required.
• the very high molecular weight salts of hyaluronic acid or xanthan gum therefore contain amounts of 0.1-1% by weight of cellulose ethers such as e.g.
• Hydroxyethyl cellulose or the cationic cellulose ethers are sufficient in amounts of 0.5-6% by weight, while e.g. Polypropylene glycols or degraded dextrans are to be contained in amounts of 2-20% by weight.
• the upper limit of the content of polymer compounds is to be chosen so that the preparation does not gel and separation is not hindered by the toughness of the phases.
• the dissolved surface-active compounds and polymer compounds can be contained in the preparations individually or as combinations of two or more such surfactants or polymers. It has been found that it is advantageous for the composition to separate if at least two different surface-active compounds or at least two different polymer compounds are present in the compositions according to the invention.
• a combination of a particularly high molecular weight polymer with a low molecular weight polymer compound has proven to be particularly suitable. For example, combinations of sodium hyaluronate with cellulose derivatives or polypropylene glycols with average molecular weights of 2000 D and more with those of 1000 D and less have proven particularly effective.
• Suitable water-soluble monohydric or polyhydric alcohols are all aliphatic alcohols, diols or polyols, preferably those with 2 to 9 carbon atoms, in amounts of at least 1% by weight are clearly soluble in water at 20 ° C. Such mono- or multi-valued

• the multiphase preparations according to the invention of the present invention separate particularly easily if ethanol or isopropanol is contained in an amount of 2-20% by weight as alcohol. In this way it was possible to obtain preparations which, after intensive mixing of the phases in the idle state, completely separate within less than 10 minutes and are in the form of separate, clear phases.
• Suitable electrolyte salts are especially water-soluble inorganic salts, e.g. Alkali halides such as table salt (sodium chloride), calcium or magnesium chloride, the sulfates of the alkali metals or magnesium, sodium bicarbonate, sodium hydrogen phosphate and sodium pyrophosphate.

• dyes were also incorporated.
• Part of the surfactant was mixed with the dye and then added.
• a part of the aqueous ether sulfate was colored with Sudan blue and another part of the ether sulfate with quinoline yellow black. In this way - after separation of the phases - an upper blue and a lower yellow phase are obtained.
