FOAM CONTROL GRANULE FOR PARTICULATE DETERGENT COMPOSITIONS

摘要

A foam control granule for use in a particulate detergent composition comprises a particulate carrier material having intraparticle porosity, carrying in its pore system a silicone-based foam control composition. The foam control composition comprises a silicone optionally in intimate admixture with a viscosity-modifying agent. The foam control composition is sufficiently mobile at processing temperatures, if necessary under the application of shear, for absorption within the porous carrier material, but has a sufficiently high viscosity at storage temperatures in the absence of shear to remain stably within the pores of the carrier material on storage.
