ABSTRACT:
The betaine compounds described correspond to the following formula (1) ##STR1## in which RCO is an aliphatic acyl radical having 6 to 22 carbon atoms, Z is a linear polyhydroxyhydrocarbon radical having at least 3 optionally oxyalkylated hydroxyl groups, m is an integer from 1 to 4, n is an integer from 1 to 4, R.sup.1 is C.sub.1 to C.sub.4 -alkyl or C.sub.2 to C.sub.4 -hydroxyalkyl and R.sup.2 is C.sub.1 to C.sub.4 -alkyl or C.sub.2 to C.sub.4 -hydroxyalkyl. The betaine compounds and the aqueous, alcoholic or aqueous-alcoholic solutions or dispersions thereof are prepared by betainization of a corresponding tertiary amine compound with a halogenocarboxylic acid or a halogenocarboxylic acid salt. The novel betaine compounds and their solutions are suitable, in particular, for the preparation of surface-active compositions for hair and body care.
