Silicone-containing microgranules are formed by a coating process using a substantially spherical or cylindrical core material such as a sucrose bead, oran enzyme-containing prill or marume. In a preferred process the core is impregnated with an absorbent such as titanium dioxide, the absorbent is impregnated with a mixture of silicone oil and hydrophobic silica and the coated granule is then coated with wax. The granules are used in detergent compositions. |
