## Abstract

In a hydrogen peroxide bleaching system it is known to use an activator which forms a peracid bleaching species; specific esters have been proposed previously as activators. The present invention defines esters having a substantive moeity which provides improved bleaching by giving peracid generation at or near the substrate surface.

## Claims

### Claim 1

A bleaching formulation consisting essentially of a hydrogen-peroxide releasing material and a chemical compound of the formula ##STR6## wherein n is 3 to about 25; R.sub.1 is a radical selected from the group consisting of alkyl, alkaryl, aryl, hydroxyalkyl and polyoxyalkylene;
R.sub.2 and R.sub.3 are each a radical selected from the group lower alkyl and hydroxyalkyl;
or two or more of R.sub.1, R.sub.2, or R.sub.3 together form an alkyl substituted or unsubstituted nitrogen-containing heterocyclic ring system selected from the group consisting of pyridine, morpholine, and pyrrolidine;
R.sub.4 is a phenyl group;
X is selected from the group of chlorine and bromine; and the total number of carbon atoms on the quaternary atom are less than about 28.
