<p>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.</p> |
