What is Polyglyceryl-2 Triisostearate?

Polyglyceryl-2 triisostearate is a synthetic ester formed by combining polyglycerol-2, a polymer of glycerol derived from plant sources or synthesized, with triisostearic acid, a branched-chain fatty acid from vegetable oils like rapeseed. This creates a thick, waxy substance commonly used in color cosmetics, lip products, and oil-in-water emulsions. As an emollient, it lubricates the skin's surface to enhance smoothness and provide a protective barrier that supports hydration. Its surfactant properties reduce surface tension, aiding in the dispersion of oils during cleansing. Primarily, it acts as an emulsifying agent by forming stable films at oil-water interfaces, ensuring even blending in creams, lotions, and foundations for consistent texture and application.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.

Benefits
