Antifoam composition containing hydrocarbon-silicon copolymer, hydrophobic filler and hydrocarbon oil

摘要

Hydrocarbon oil based antifoams compositions containing a hydrocarbon-silicon copolymer, a hydrophobic filler, an organo-silicone surfactant, a hydrocarbon carrier oil and optionally a silicone oil act to effectively defoam concentrated solutions, including those containing ionic surfactants or protein based solutions. The use of the hydrocarbon oil based silicone antifoams represents an inexpensive route to defoams difficult solutions.
