Granular detergent compositions, particularly phosphate-containing detergent compositions, contain a specific hydrophobic peroxyacid bleaching system and a specific anionic surfactant system. The compositions are suitable for use in laundry washing methods.

Detergent compositions having a specific hydrophobic peroxyacid bleaching system and anionic surfactant

Granular detergent compositions and in particular low density, phosphate containing detergent compositions comprise a specific bleaching system containing hydrophobic peracid bleach and hydrophilic peracid bleach and a peroxide source. These detergent compositions have specific low levels of available oxygen from hydrophobic aid hydrophilic peroxyacid bleach, specific ratios of available oxygen from the hydrophobic peracid bleach to the hydrophilic peracid bleach and specific ratios of available oxygen of the peroxide source to the available oxygen of the peracids. These specific mixed bleach systems are useful for sanitization or reduction of bacterial activity.

Bleaching compositions

Detergent composition comprising cellulase enzyme and nonionic cellulose

Detergent composition comprising an amylase enzyme and a nonionic

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.
