发明名称 PROCESS FOR THE PREPARATION OF QUATERNARY AMMONIUM SALTS
摘要 Compounds of the formula <IMAGE> in which R1 is long-chain alkyl, R2 and R3 are each lower alkyl and X(-) is an anion, are prepared by quaternizing amines of the formula R1R2R3N 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.
