    摘要: A method for the synthesis of betaines of the general formula ##STR1## by quaternizing the fatty acid amide dialkylamines of the general formula ##STR2## with .omega.-halogenalkylcarboxylic acids of the formula X-(CH.sub.2).sub.y COOH, wherein X is a halogen group, or their salts in aqueous solution, the reaction being carried out within a temperature range of 115.degree. to 180.degree. C., until organically bound chlorine can no longer be detected, the fatty acid amide dialkylamine optionally being quaternized partially or completely in a first step at 80.degree. to 100.degree. C.

    摘要: The invention relates to mild, aqueous, surfactant preparations for cosmetic purposes and as detergents. These preparations contain, as surfactants, betaines of the general formula ##STR1## in which R is an alkyl group with 7 to 21 carbon atoms, 20 to 100% by weight of the betaines used as R group having an alkyl group with 7 to 9 carbon atoms, in an amount of 1.0 to 40% by weight of the preparation used. These preparations are distinguished by their exceptionally mild and low irritating properties when used, for example, in face lotions, shampoos or lotions.
