ABSTRACT:
The invention relates to a powder bleach composition comprising a plurality of particles wherein substantially each of the particles comprises soda ash and sufficient sodium percarbonate to provide about 1 to 6 weight percent available oxygen content. The bleach composition is made by contacting particulate soda ash, either anhydrous sodium carbonate or sodium carbonate monohydrate, with sufficient of a spray of an aqueous solution of hydrogen peroxide, the contacting being at a temperature from about 35.degree. C. to about 70.degree. C. to provide the aforedescribed bleach composition. The powder bleach composition is recovered from the contacting step once sufficient reaction has occurred to provide sufficient sodium percarbonate so that the bleach composition has from about 1 to about 6 weight percent available oxygen and a remainder which comprises soda ash and minor additives.
