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.
Claims7
A detergent formulation containing an effective bleaching amount of a heterocyclic nitrogen amidic heteroatom containing (poly)peroxycarboxylic acid bleaching agent having the formula (I):
- R--(CH.sub.2).sub.m --R' (I)
- (1) R and R' are the same as each other and represent a group of formula II:
- ##STR3## or (2) R represents a hydrogen atom and R' represents a group defined by formula II above, and wherein the other symbols have the following meanings:
- 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 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, and at least one additional additive selected from builders, surfactants, soaps, zeolites, hydrotropic agents, corrosion inhibitors, enzymes, optical bleaches, stabilizers or other peroxidic compounds.
