A particulate antifoam ingredient suitable for incorporation in a detergent powder product comprises an oily antifoam active substance effective at low wash temperatures, for example, silicone oil/hydrophobic silica or alkyl phosphate/petroleum jelly, on a carrier of swollen hydrated hydrophilic starch. The antifoam ingredient combines improved storage stability and improved flow properties with rapid release of the antifoam active substance at all wash temperatures. |
