一种两性离子多胺，包含线型或支化的疏水性多胺主链，该主链含有2-10个叔氨基氮原子和在2个叔氮原子之间的隔离基团，其中该隔离基团例如选自C#-[8]-C#-[16]亚烷基、C#-[5]-C#-[15]亚环烷基，其中式(IV)中R＝C#-[1]-C#-[22]烷基或C#-[7]-C#-[22]芳烷基，n＝3-6，该多胺主链中的至少1个叔胺端基含有2个式(V)或(VI)的基团，其中A表示环氧乙烷单元、环氧丙烷单元、环氧丁烷单元和四氢呋喃单元，n是1-50的数，X是阴离子基团，如-SO#-[3]M，其条件是式(VI)中1个X也可以是氢，M是氢、碱金属或铵，或含有1个式(V)或(VI)的基团和1个选自式(VII)基团、C#-[1]-C#-[22]烷基和C#-[7]-C#-[22]芳烷基的基团，A和n的含义与式(V)或(VI)中所述相同，所述聚醚多胺的分子量可高达9000，任选地含有高达100％季铵化氮原子，一种生产两性离子多胺的方法，包含使所述多胺烷氧基化、在烷氧基化多胺中引进阴离子基团以及在引进阴离子基团之前或之后任选地使其季铵化。该两性离子多胺可用在洗涤剂中。∴ A zwitterionic polyamine comprising a linear or branched hydrophobic polyamine backbone having 2 to 10 tertiary amino nitrogen atoms and a spacer between two tertiary nitrogen atoms wherein the spacer is, for example selected from C8-C16-alkylene, C5-C15-cyloalkylene, wherein in formula (IV) R = C1- to C22-alkyl or C7-C22-aralkyl and n = 3 to 6, at least one tertiary amine end group of the polyamine backbone contains two groups having formula (V) or (VI), wherein A means an ethylene oxide unit, a propylene oxide unit, a unit of butylene oxides and a tetrahydrofuran unit, n is a number of from 1 to 50, X is an anionic group such as -SO3M, with the proviso that in formula (VI) one X may also be hydrogen and M is hydrogen, alkali metal or ammonium, or contains one group of formula (V) or (VI) and one group selected from radicals consisting of formula (VII), C1- to C22-alkyl and C7-C22-aralkyl, the meaning of A and n is the same as in formula (V) or (VI), said zwitterionic polyetherpolyamine having a molecular weight up to 9000 and optionally containing up to 100 % of the nitrogen atoms quaternized, and a process for the production of zwitterionic polyamines by alkoxylating said polyamines, introducing anionic groups into the alkoxylated polyamines and optionally quaternizing them before or after the introduction of anionic groups. The zwitterionic polyamines are used in detergents.
