    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.

    摘要： Disclosed is a process for making nonphosphated automatic dishwashing detergents which have granular form and comprise a conventional nonphosphorus builder system consisting essentially of an organic builder salt (such as citrate) and a dispersant (such as a polyacrylate); and an oxygen bleach system comprising a chelant (such as ethylenediamine disuccinate) and a bleach active (such as perborate or percarbonate) optionally with enzymes and/or dry-mixed hydrous silicates. The invention secures stable, free-flowing granules by a premix step in which the chelant and dispersant are brought together; a drying step using conventional equipment; and one or more admix steps in which the bleach active is mixed with the product of the drying step.
