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, R is C.sub.4-17 alkyl or both.
Claims10
A bleaching composition comprising:
- (a) a peracid precursor having the general structure:
- ##STR35## wherein R is selected from the group consisting of straight and branch chain C.sub.1-20 alkyl and cycloalkyl;
- n is an integer from 1 to 6;
- X is selected from the group consisting of methylene and oxygen;
- R.sup.11 is selected from the group consisting of straight and branch chain C.sub.1-20 alkyl, aryl, alkylaryl, and completes a heterocycle;
- and R.sup.12 is selected from the group consisting of nothing, C.sub.1-20 alkyl, aryl, and alkylaryl;
- and
- (b) a bleach effective amount of a source of hydrogen peroxide.
