Abstract
Abstract Quaternary ammonium compounds of the formula I ##STR1## wherein R 1 is C 8 -C 24 alkyl, cyclohexyl or aryl, X and Y are hydrogen or methyl, only one X or Y being methyl at the same time, n is an integer of from 1 to 20, R 2 and R 3 are lower alkyl or benzyl and A is an anion. These compounds are made by common alkylation reaction of the corresponding non-quaternized compounds. They are used as surfactants, especially in hair care compositions.

Claim 1
Independent Claim
96 words
Quaternary ammonium compounds of the formula ##STR12## in which R 1 is saturated or unsaturated alkyl radical of 8 to 24 carbon atoms, a cyclohexyl radical or an aryl radical optionally substituted by alkyl groups, X and Y stand for a hydrogen atom or a methyl radical, however, X and Y not being methyl at the same time, n is an integer of from 1 to 20, R 2 and R 3 stand for an alkyl radical of 1 to 4 carbon atoms or a benzyl radical, and A represents the methosulfate ion, chloride or bromide.
