摘要： There is provided a process for ma ing composite particulates comprising from about 1% to about 50% by weight of discrete particles of water-insoluble diacyl peroxide having a mean particle size of less than about 300 microns and from about 30% to about 99% by weight of a carrier material which melts in the range of from about 38.degree. C. to about 77.degree. C. This preparation process involves the steps of (i) mixing the particles of water-insoluble diacyl peroxide into the carrier material while the carrier material is in a molten state and then (ii) rapidly cooling and solidifying the resultant mixture and thereafter (iii) wor ing the solidified mixture if or as necessary to form the composite particulates therefrom. Detergent compositions containing the composite particulates are also provided.
