摘要： A process for washing a substrate. The process involves providing a detergent composition that includes a surfactant and an antifoam. The antifoam comprises a hydrophobic fluid having a surface tension of at least 27 mN/m and less than 40 mN/m and a finely divided solid hydrophobic filler dispersed in the hydrophobic fluid. The process further involves washing the substrate in an aqueous medium with the detergent composition. The antifoam does not affect foaming during the washing step. During the washing step, the detergent composition is applied to the substrate. The process further involves rinsing the substrate with the applied detergent composition with water, whereby foaming during the rinsing step is inhibited.

摘要： 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.
