ABSTRACT:
There is disclosed an improved process for making a lubricant grease wherein a basic oil is mixed with a thickening compound, a polar compound and an additive or additives to impart desired characteristics to the grease. The improvement includes selecting the basic oil from the group consisting of a polyolester, a silicone oil, a mineral oil, a vegetable oil, glycerine and propylene glycol. The improvement further includes first mixing the basic oil with a mixture of two polar agents in a vessel under constant stirring at a temperature and pressure sufficient to obtain a homogeneous mixture and then and only then reacting the homogenous mixture with the additive or additives and a thickening agent.
