Stabilised bleaching compositions.

摘要

There is provided a bleaching composition comprising alkali metal percarbonate as an oxygen releasing compound and alkali metal carbonate or bicarbonate particles of defined size (mean particle size of 250 mu m or greater) preferably fewer than 20% of the particles have a particle size of below 250 mu m and fewer than 5% of the particles have a particle size of below 150 mu m). The particulate bleaching composition may form a component of a machine dishwashing composition, a bleach booster composition or in particular a laundry detergent composition. The percarbonate has increased storage stability in the compositions of the invention.
