Abstract
A process for preparing carboxylates of polyoxyalkylene siloxanes and -amines, alkylpolyoxyalkylenes, polyoxyalkylene block polymers, alkylamidepolyoxyalkylenes and alkylpolyglucosides comprising subjecting a primary hydroxyl group-containing polyoxyalkylene compound or alkylpolyglucoside to mild oxidiation. The invention also relates to the novel polyoxyalkylene amine and alkylamidepolyoxyalkylene carboxylates prepared by the process.
