ABSTRACT:
Bleaching compositions, laundry and automatic dishwashing detergent compositions comprising particular neutral or anionically charged substituted bleach activators are provided. More specifically, the invention relates to compositions which provide enhanced cleaning/bleaching benefits through the selection of perhydrolysis-selective bleach activators having specific leaving groups with a conjugate acid pK.sub.a above 13 and with specific ratios of the rate of perhydrolysis to the rate of hydrolysis and the rate of perhydrolysis to the rate of diacylperoxide production. Included are preferred activator compounds and methods for washing fabrics, hard surfaces, and tableware using the activators.
