Patent ID: 7709437

Claim:
A method of preparing a bleach composition consisting of: mixing one of a bleach activator and a bleach component with a binder for between 2 to 10 minutes at a temperature of between 30-100 degrees C. to melt the binder and form a granulate wherein the binder substantially coats the one of a bleach activator and a bleach component; and adding to the granulate the other of the bleach activator and the bleach component to form a co-granulate; with a coating material selected from the group consisting of waxes, silicones, soaps, anionic surfactants, cationic surfactants, anionic polymers and cationic polymers; and optionally processing the co-granulate to produce a median particle size between 300 and 900 microns, and a density between 800 and 1200 grams/liter coating the co-granulate; the bleach activator being selected from the group consisting of an N— or O-Acyl compound, an acylated alkylene diamine, tetra acetyl glycouril, an N-acylated hydantoine, a hydrazine, a triazole, a hydratriazine, a urazole, a di-ketopiperazine, a sulfurylamide and a cyanurate; the bleach component being selected from the group consisting of sodium percarbonate and sodium perborate; and the binder being selected from the group consisting of fatty acids, fatty acid polyol esters, polyglycols and fatty alcohol oxyalkylates.
