Packaged free flowing bleach activator product

Claim 1

Process for preparing free flowing granular bleach activator product comprising the steps of (a) contacting powdered bleach activator with molten organic compound to form granular product with a particle size ranging from about 1 to about 4 mm maximum dimension, said granular product comprising a matrix of (i) from about 15% to about 70% bleach activator and (ii) from about 85% to about 30% of said organic compound, said bleach activator being selected from the group consisting of tetra acetyl ethylene diamine and tetra acetyl methylene diamine and mixtures thereof, said organic compound being selected from the group consisting of C 10 -C 24 primary and secondary alcohol ethoxylates having an average of at least 15 ethylene oxide groups per mole of alcohol, C 8 -C 18 alkyl phenol ethoxylates containing at least 20 ethylene oxide groups per mole of alkyl phenol, polyethylene glycols of molecular weight greater than 4000, and mixtures thereof; (b) contacting the granules of said granular product with sodium tripolyphosphate particles of size less than 500 microns to provide a surface coating thereon of said sodium tripolyphosphate particles at a level ranging from about 0.1% to about 30% by weight of said matrix; to thereby provide granular bleach activator product with a flowability defined by a cake strength of less than about 0.9 kg and characterized by a rate of dispersion such that after addition into a standard detergent peroxy bleach solution at least 50% of the organic peroxy bleach theoretically available from the bleach activator is generated within 8 minutes.
