Abstract
Abstract Amino-derivative (poly)peroxycarboxylic acid monopersulfates having the formula: ##STR1## wherein the symbols have the following meanings: R, R 1 and R 2 , which may be alike or different from one another, represent hydrogen atoms, alkyl groups which may be optionally substituted with the proviso that at least one of them is a hydrogen atom; n is an integer different from 0; said --(CH 2 ) n -- group may be also interrupted by CONR 3 groups; and wherein R 3 represents a hydrogen atom or an alkyl or aryl group. A process for their preparation and their use as bleaching agents are also disclosed.
