Abstract
Heterocyclic (poly)peroxycarboxylic acids having a N-amidic heteroatom, which have the formula: R--(CH.sub.2) .sub.m --R' (I) wherein: R and R', alike or different from each other, represent hydrogen atoms or a group: ##STR1## with the proviso that at least one of R and R' shall be different from H, and wherein the other symbols have the following meaning: R" represents a hydrogen atom or any other substituent non-reactive in the presence of the active oxygen of the peroxycarboxylic group and/or under the preparation conditions; m represents a number between 1 to 12; n represents a number selected from 0, 1 and 2; p represents a number between 1 and 3; their process of preparation and their use as bleaching agents.
