Surfactant mixtures for improving the deposition of active substances and for reducing the skin irritant action
A use of mixtures of surfactants which form multilamellar liquid-crystalline structures, where the surfactants are chosen from at least two of the following groups formed from isethionates, taurates, sarcosinates, acyl lactylates, acyl glutamates, fatty acid-protein condensates, PEG stearates, PEG distearates with an HLB value of less than 10, alkyl polyglycosides and betaines for reducing the skin irritant action of cosmetic and/or pharmaceutical formulations which are applied to the skin, and for improving hair structure is described.
1 . The use of surfactant mixtures of isethionates, acyl lactylates and acyl glutamates or of isethionates, acyl lactylates and alkyl glucosides which form multilamellar liquid-crystalline structures for reducing the skin irritant action of cosmetic and/or pharmaceutical formulations which are applied to the skin, and for improving hair structure.
2 . The use of surfactant mixtures of isethionates, acyl lactylates and acyl glutamates or of isethionates, acyl lactylates and alkyl glucosides which form multilamellar liquid-crystalline structures in cosmetic and/or pharmaceutical formulations which comprise active substances which are chosen for organic photoprotective filters, antidandruff active substances and other pharmaceutical active substances, keratolytics, antioxidants, plant extracts, oils, waxes and mixtures thereof, for improving the application of the active substances to the skin and the hair.
3 . The use as claimed in one of claims 1 or 2 , characterized in that, in the surfactant mixture, surfactants from the at least three groups are present in amounts of in each case at least 10% by weight.
4 . The use as claimed in one of claim 1 , characterized in that the cosmetic and/or pharmaceutical formulations are rinse-off formulations.
5 . A mixture of 20 to 90% by weight of a surfactant mixture of isethionates, acyl lactylates and acyl glutamates or isethionates, acyl lactylates and alkyl glucosides which form multilamellar liquid-crystalline structures, and 10 to 80% by weight of water, polyol or mixtures thereof.
6 . The mixture as claimed in claim 5 , characterized in that, in the surfactant mixture, surfactants from the at least three groups are present in amounts of in each case at least 10% by weight.
7 . A cosmetic and/or pharmaceutical rinse-off formulation comprising 0.2 to 20% by weight of a mixture according to one of claims 5 or 6 and 0.1 to 50% by weight of active substances which are chosen from organic photoprotective filters, antidandruff active substances and other pharmaceutical active substances, antioxidants, plant extracts, oils, waxes and mixtures thereof.
8 . The use of a mixture as claimed in one of claims 5 or 6 for producing hair-and/or skin cleansing compositions.
9 . A hair-and/or skin-cleansing composition comprising a mixture as claimed in one of claims 5 or 6 .
