Abstract
A self-activating organoclay rheological additive for non-aqueous fluid systems has been produced comprising a homogeneous mixture of an organically modified montmorillonite clay and two solid waxes, the waxes being the activators for the organic clay. The two waxes are finely divided particles of glyceryl tri-12-hydroxystearate and an amide wax having the formula ##EQU1## where n is from 2 to 18, HSA is the acyl radical of 12-hydroxystearic acid, R is hydrogen or the acyl radical of 12-hydroxystearic acid. The montmorillonite clay is modified with a quaternary ammonium compound.
