Zusammenfassung:	Bis-betaine-amine oxides of the formula (I) in which R is a saturated or an olefinically unsaturated hydrocarbon radical having 1 to 3 double bonds and 8 to 22 carbon atoms, n1 and n2 each is an integer of from 2 to 3, n1 and n2 optionally being identical or different, m1 and m2 each is an integer of from 1 to 4, m1 and m2 optionally being identical or different, and a, b, c and d, being identical or different, each is a number of from 1 to 5, with the proviso that the sum (a+b+c+d) is at most 10. The compounds are prepared from primary amines of the formula RNH2, by dicyanoalkylation, hydrogenation, ethoxylation, reaction with alkali metal salts of omega -halocarboxylic acids, and subsequent oxidation with hydrogen peroxide. They are surfactants of mild action and suitable for formulating cosmetic and industrial cleaning agents.
