Foam control granule for particulate laundry detergent compositions

Abstract From the Canadian patent

Foam control granules, for use in particulate laundry detergent compositions comprise a mobile hydrophobic foam control agent preferably silicone oil in , admixture with hydrophobic silica optionally combined with a mixture of a hydrocarbon such as petroleum jelly and an alkylphosphoric acid salt sorbed , onto a porous absorbent inorganic carrier comprising or consisting of anhydrous sodium carbonate, preferably light soda ash. When such granules are prepared by mixing and granulating in a higher shear mixer/granulator the , addition of from 1 to 10 wt.% water after mixing and granulation results in granules having improved flow properties.
