ABSTRACT:
The invention provides novel bleaching compositions comprising peracid precursors having oxynitrogen leaving groups. Peracid precursors containing these leaving groups provide new, proficient and cost-effective compounds for fabric bleaching.
These compounds have the general structures: ##STR1## wherein R is a straight or branched chain C.sub.1-20 alkyl, alkoxyl, cycloalkyl and mixtures thereof; R.sup.1 contains at least one carbon atom which is singly bonded directly to N; n is an integer from 1 to 6 and X is methylene or a heteroatom; or ##STR2## wherein n is the same as in (I); but R.sup.2 contains a carbon atom doubly bonded directly to N, and, either X is a heteroatom or nothing, R is C.sub.4-17 alkyl or both.
