ABSTRACT:
A defoamer composition comprising a precipitated hydrophylic silica suspended in a water-immiscible inert liquid carrier, and reacted in situ with specific molar proportions of a trichloro-organosilane and a dichloro-organosilane, preferably in this respective order, to yield a stable hydrophobic silica suspension in an inert carrier, useful as a defoaming agent for aqueous systems, being effective at concentrations as low as 0.0005 percent. When one of said chloro-organosilanes contains an unsaturated bond, the composition may be further halogenated or sulfated.
