Compounds of the formula ##STR1## in which R 1 is long-chain alkyl, R 2 and R 3 are each lower alkyl and X⊖ is an anion, are prepared by quaternizing amines of the formula R 1 R 2 R 3 N with ethylene oxide in the presence of acid. This gives the quaternary compounds in virtually quantitative yield. The compounds are particularly suitable for use in hair cosmetics. |
