Abstract
Bleaching compositions, laundry and automatic dishwashing detergent compositions comprising particular quaternary-substituted bleach activators, are provided. More specifically, the invention relates to compositions which provide enhanced cleaning/bleaching benefits though the selection of quaternary-substituted bleach activators having specific leaving groups with a conjugate acid pKa 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.
