ABSTRACT:
Suds control agents for addition to detergent compositions are prepared by a granulation process. In the process core particles of gelatinised starch are granulated with a silicone oil admixed with hydrophobic silica. The granules are then coated with wax by spraying from a solution in an organic solvent. Typically the granules produced contain 45-55%, silicone oil compound 35-50% and wax 7-15% gelatinized starch.
