Abstract
Composition for washing keratinous materials, especially the hair and the skin, characterised in that it comprises, in an aqueous medium, at least one silicone, at least one surfactant possessing detergent properties and at least one alcohol having 27 to 44 carbon atoms and containing one or two ether and/or thioether or sulphoxide group(s), corresponding to the formula (I): ##STR1## in which R.sub.1 and R.sub.2, which may be identical or different, denote linear C.sub.12 to C.sub.20 alkyl groups; PA1 X denotes an oxygen atom, a sulphur atom or a sulphoxide group; PA1 Y denotes an oxygen atom, a sulphur atom, a sulphoxide group or a methylene group; PA1 in the case where Y denotes a methylene group, the sum of the numbers of carbon atoms in R.sub.1 and R.sub.2 varies from 24 to 40, and preferably from 26 to 36, inclusive, and when Y does not denote a methylene group, the sum of carbon atoms in R.sub.1 and R.sub.2 varies from 24 to 40 inclusive, and preferably from 28 to 36 inclusive; when X or Y denotes sulphoxide, Y or X does not denote sulphur.
