Abstract
A sulfonate-based grease composition and method of manufacture comprising the addition of one or more glycerol derivatives. The glycerol derivative acts to optimally disperse the thickener in the grease such that the conventional step of milling the grease may not be needed. The glycerol derivative reacts with water to form in-situ complexing acids, which may replace at least some of the normally used complexing acids for reacting with calcium containing bases. The greases according to preferred embodiments have a high dropping point, improved thickener yield, and faster conversion time.
