ABSTRACT:
Defoaming formulations for aqueous systems are produced by treating silicates such as sodium magnesium aluminosilicates with a source of aluminum to provide an aluminum content therein in the range of 0.1 to 2.5 wt. %, preferable 0.3 to 1.2 wt. %, and forming a defoaming formulation from said aluminum treated silicate by hydrophobizing with a silicone fluid, and dispersing in oil and/or water to form a defoamer formulation.
