A particulate antifoam ingredient suitable for incorporation into a detergent powder comprises an antifoam active material, for example, a mixture of silicone oil, petroleum jelly, hydrophobic silica and alkyl phosphate, sorbed onto a porous absorbent water-soluble carbonate-based inorganic carrier of high pore volume and pore diameter, for example, light soda ash or crystal-growth-modified Burkeite. |
