    • Betaine-amine oxides of the formula ##STR1## in which R denotes alkyl, alkenyl or hydroxyalkyl, each of which has 8-22 carbon atoms, R.sup.1 denotes hydrogen or methyl, R.sup.2 denotes ethylene, propylene or 2-hydroxypropylene, R.sup.3, R.sup.4 and R.sup.5 can be identical or different and denote C.sub.1 -C.sub.3 -alkyl or a group of the formula ##STR2## or R.sup.3 denotes a group of the formula --R.sup.2 --BR.sup.4 R.sup.5, X denotes a direct bond or a group of the formula--CO--,A and B denote a group of the formulae ##STR3## it being necessary for at least one amine oxide group and at least one betaine group to be present, a denotes 0 or 1, b denotes 1, 2 or 3, n denotes a number from 0 to 10 and m denotes 1, 2 or 3. These compounds are obtained by partially quaternizing the parent polyamines with the alkali metal salt of an .omega.-halogenocarboxylic acid and then oxidizing the non-quaternized nitrogen atoms. These betaine-amine oxides are suitable for use as surfactants in cleansing agents.
    • 其中R表示烷基,烯基或羟烷基,其中每一个具有8-22个碳原子,R1表示氢或甲基,R2表示乙烯,丙烯或2-羟基亚丙基,R3,R4和 R 5可以相同或不同,表示C 1 -C 3 - 烷基或式“基团”或R 3表示式-R 2 -BR 4 R 5的基团,X表示直接键或式-CO-的基团, A和B表示至少一个氧化胺基团和至少一个甜菜碱基团所需的一组式(IMAGE),a表示0或1,b表示1,2或3,n表示数 0至10,m表示1,2或3.这些化合物通过将母体多胺与ω-卤代羧酸的碱金属盐部分季铵化,然后氧化未季铵化的氮原子而获得。 这些甜菜碱 - 胺氧化物适合用作清洁剂中的表面活性剂。
