An antifoam granule includes a carrier and an antifoam compound deposited on the carrier. The antifoam granule is formed using a method that includes providing an emulsion and contacting the emulsion with a carrier to deposit the antifoam compound on the carrier and form the antifoam granule. The emulsion includes an oil phase, an aqueous phase, and a silicone polyether. The oil phase includes an antifoam compound. The antifoam compound includes a hydrophobic fluid and a hydrophobic filler dispersed in the hydrophobic fluid. The aqueous phase includes a binder and water. The emulsion is formed using a method that includes combining the oil phase, the aqueous phase, and the silicone polyether to form the emulsion. The antifoam granule is also utilized in a method of facilitating rinsing of a detergent from a substrate that includes applying the detergent, including the antifoam granule, to the substrate and rinsing the substrate.

A granulated antifoam composition comprising an antifoam, a siloxane wax binder, and a carrier. The antifoam includes a hydrophobic fluid wherein the hydrophobic fluid has a surface tension which is greater than or approximately equal to the dynamic surface tension of an aqueous dispersion of the detergent at above the critical micelle concentration of the surfactant and less than about 62 mN/m. The antifoam further includes a finely divided solid hydrophobic filler dispersed in the hydrophobic fluid.
