Abstract
The present invention is related to an aqueous cleansing composition for keratin fibres, especially human hair, comprising at least two anionic surfactants comprising at least one amide group in their molecules. The first object of the present invention is an aqueous cleansing composition comprising at least two anionic surfactants comprising at least one amide group in their molecules and substantially frees of alkyl sulphate and alkyl ether sulphate surfactants. The two anionic surfactants comprising at least one amide group in their molecule is preferably selected from surfactants of the following structure
wherein R1 is a saturated or unsaturated, straight or branched alkyl chain with 7 to 17 C atoms, R2 is H or a methyl, R3 is H, COO−M+, CH2COO−M or COOH, n is 0 to 2, X is COO− or SO3− and M is independent from each other H, sodium or potassium. The cleasning composition comprise furthermore amphoteric and non-ionic surfactants.
