Abstract (en)
[origin: EP0267046A2] A bleaching composition characterised in that it comprises: (a) a peracid precursor corresponding to the following general formula: (I) R-X-(CH2)n @-O-N-R<1> wherein R represents C1-C20 alkyl, alkoxyl, or cycloalkyl; R<1> represents a group which contains at least one carbon atom which is singly bonded directly to N; n represents an integer of from 1 to 6; and X represents methylene or a heteroatom; or (II) R-X-(CH2)n @-O-N=R<2>, wherein n is as defined above; R<2> represents a group which contains a carbon atom doubly bonded directly to N, and, either X represents a heteroatom, R represents C4-C17 alkyl, or both; (b) a bleach-effective amount of a source of hydrogen peroxide; and, optionally, (c) an adjunct selected from surfactants, builders, fillers, enzymes, fluorescent whitening agents, pigments, dyes, fragrances, stabilizers and buffers is disclosed. Peracid precursors containing such oxynitrogen leaving groups provide new, proficient and cost-effective compounds for fabric bleaching. v
