Abstract

A process for manufacturing granules containing a silicone anti-foam comprises spraying a liquefied mixture of silicone and wax onto an agitated bed of an absorbent. One suitable absorbent is gelatinised starch. The silicone material is a mixture of an oil and a hydrophobic solid. Preferred solids are hydrophobed silica and complex nitrogen compounds, for example ethylene or methylene bis-stearimide.
