APPLICATION OF POLYALDEHYD CARBOXYLIC ACID IN A HAIR AND RINSE AGENT AND HAIR AND RINSE AGENT

摘要

Preparations for washing or rinsing hair contain polyaldehydocarboxylic acids having an average molecular weight of from 600 to 10,000, a carboxyl group content of from 5 to 9 and preferably from 7 to 9 and an aldehyde group content of from 1 to 5 and preferably from 1 to 3 per 10 monomer units, or water-soluble salts thereof. These additives reduce the smoothness of dry hair and improve body and stylability after washing. The polyaldehydocarboxylic acids are preferably used in conjunction with hair-conditioning linear alkyl and/or alkylether phosphate salts, alkyl, hydroxyalkyl and/or aminoalkyl phosphonate salts. Preferred embodiments are hair shampoos containing from about 1 to about 10% by weight of the polyaldehydocarboxylic acids and from about 5 to about 50% by weight of anionic surfactants of the alkyl sulfate and/or alkylether sulfate type and hair rinses containing from about 1 to about 10% by weight of hair-conditioning alkyl and/or alkylether phosphate salts and/or alkane phosphonate salts.
