ABSTRACT:
Particulate foam control agents for powder detergents consist of 1 part by weight of silicone antifoam, not less than 0.3 part by weight of a water insoluble fatty acid or a fatty alcohol with 12 to 20 carbon atoms and a melting point in the range 45 to 80% or a monoester of glycerol and a fatty acid and a native starch carrier material. They give improved storage stability and require less organic material than the prior art agents.
