Abstract

Anti-foam granules for use in detergent compositions to prevent over-foaming in automatic washing machines contain hydrophobic silica and a mixture of liquid and solid hydrocarbons. This active material is sorbed on a core material which produces a mechanical action on addition to water, for example sodium perborate monohydrate or gelatinised starch.
