Abstract
An overbased calcium magnesium sulfonate grease composition and method of making such grease without using any conventional non-aqueous converting agents, such as hexylene glycol, as a pre-conversion ingredient. The addition of magnesium sulfonate as an ingredient prior to conversion appears to act as a new, non-conventional converting agent, resulting in greases with improved thickener yield and excellent dropping point.
