Partially saponified triglycerides, their methods of manufacture and use as polymer additives

A homogeneous partially saponified fat or oil triglyceride composition having components consisting essentially of

• about 5 to about 95 percent by weight of an alkali or alkaline earth metal salt of a fatty acid of said triglyceride,
• about 95 to about 5 percent by weight of a mixture of monoglyceride, diglyceride and triglyceride derived from said triglyceride, said homogeneous composition achieved in the absence of a compatibilizing agent for said components,
• said triglyceride selected from tallow, fully hydrogenated tallow, soybean oil, partially hydrolyzed soybean oil, fully hydrogenated soybean oil, fully hydrogenated high erucic rapeseed oil, fully hydrogenated castor oil, fully hydrogenated palm oil, canola oil, coconut oil, fully hydrogenated coconut oil, sunflower oil, lard, partially hydrogenated lard or macadamia oil.

A method of making a homogeneous partially saponified triglyceride composition comprising

• reacting a triglyceride with a metal base in the presence of a catalyst to produce a metal salt of a fatty acid of said triglyceride and a mixture of monoglyceride, diglyceride and triglyceride derived from said triglyceride, wherein the stoichiometry of the metal base to the triglyceride in the reaction mixture produces the partially saponified triglyceride composition having about 5 to about 95 percent by weight of said metal salt and about 95 to about 5 percent by weight of said glyceride mixture, and
• conducting said reaction at a temperature to obtain solubilization of said metal salt in said mixture to achieve a homogeneous partially saponified triglyceride composition.
