Abstract

Novel quaternary oxalkylated polyesters prepared from oxalkylated fatty amines by polycondensation with a dicarboxylic acid and subsequent reaction with an alkylene oxide and a carboxylic acid or a mineral acid or with a quaternizing agent such as methyl chloride, are described. The compounds are suitable for use as cosmetic active compounds, in particular for cosmetic care of the hair.
