Triisostearoyl Polyglyceryl-3 Dimer Dilinoleate

What is Triisostearoyl Polyglyceryl-3 Dimer Dilinoleate?

Triisostearoyl Polyglyceryl-3 Dimer Dilinoleate is a synthetic ester formed by reacting polyglyceryl-3 dimer dilinoleate with three molecules of isostearic acid. This branched, high-molecular-weight compound belongs to the polyglyceryl ester family, commonly used in color cosmetics such as lipsticks, foundations, and mascaras. It functions by creating a thin, flexible film on the skin that enhances product adhesion, disperses pigments evenly, and imparts a silky, non-greasy finish. In formulations, it stabilizes anhydrous systems, boosts shine, and mimics natural sebum for comfortable wear. Derived from plant-sourced fatty acids like dilinoleic and isostearic acids combined with polyglycerol, it excels in oil-based products where lightweight emollience and long-lasting smoothness are desired without tackiness or heaviness.
