Abstract
A method of providing a foam control agent with 1 to 30 parts of a silicone antifoam and 70 to 99 parts of a zeolite carrier, with the ability to release some of the antifoam within 10 minutes of being dispersed in an aqueous surfactant solution, by depositing 5 to 70% of the antifoam of an organopolysiloxane polyoxyalkylene copolymer, onto the zeolite carrier not later than depositing the silicone antifoam. Also claimed is the use of the copolymer to achieve that end and compositions where the antifoam is branched or high viscosity. Also claimed is encapsulated agents.
