PURPOSE: To prepare an additive for delayed release defoaming agent laundering by uniformly packing an defoaming agent onto a carrier consisting of water-solu ble denatured cellulose and agglomerating the carrier in the presence of a pre scribed amt. of a solvent, then removing the solvent. CONSTITUTION: The defoaming agent consisting essentially of one or more kinds of the conventional silicon is uniformly packed onto the carrier consisting of the water-soluble denatured cellulose. The carrier is then mixed in the presence of the solvent of the amt. sufficient for the carrier to form the agglomerate and thereafter the solvent is removed from the carrier, by which the additive for delayed release defoaming agent laundering is produced. The defoaming agent described above is adequately a mixture of 0.1 to 2.0 wt.% per 100 pts.wt. the conventional dry detergent. The water-soluble carrier includes the carrier composed of one or more kinds of the ingredients selected from substd. alkyl ether of cellulose, unsubstd. alkyl ether of cellulose or the like. |
