Abstract:
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.
