Abstract
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.
