An anti-foaming agent granular product is disclosed, which comprises (a) a silicone anti-foaming agent; (b) water-soluble starch, a modified water-soluble starch or a derivative thereof; wherein an (a)/(b) weight ratio is from 0.1 to 0.5 and a total amount of (a) and (b) is from 30 to 80% by weight based on the total weight of the granular product, (c) from 0.5 to 40% by weight, based on the total weight of the granular product, of an inorganic builder or a clay mineral, and (d) from 10 to 40% by weight, based on the total weight of the granular product, of an organic binder having a melting point or softening point of from 40 to 160°C. The anti-foaming agent granular product does not undergo reduction in anti-foaming effect due to oozing of silicone during storage and has satisfactory solubility even in cold water.
