Kunz, Werner ; Kellermeier, Matthias ; Klein, Regina ; Maurer, Eva ; Touraud, Didier


The invention pertains to a choline compd. of general formula R-A-SO3- [(H3C)3N-CH2-CH2-OH]+ where A stands for O or a group of formula [O-B]n-O-; where B is an alkyl group with 2-4 C atoms; and n = 1-20; R stands for a satd. or unsatd. linear or branched alkyl group with 8-30 C atoms. The compds. can be used as surfactants. Compared to their alkali metal analogs, these choline compds. have better compatibility with skin and better soly.
