  • Partially saponified triglycerides, their methods of manufacture and use as polymer additives
    Patent number: 6194502
    Abstract: Homogeneous partially saponified triglycerides are made consisting essentially of metal salts or fatty acid and mono-, di- and triglycerides without the need for a compatibilizing additive. The PSTs are useful as lubricants, antistats and neutralizers for polymers. The PSTs are formed in situ by reacting a fat or oil under controlled conditions with a catalyst and at a sufficiently high temperature to achieve a homogeneous composition.
