Polyglyceryl-2 Tetraisostearate

What is Polyglyceryl-2 Tetraisostearate?

Polyglyceryl-2 tetraisostearate is a multi-functional ingredient formed by esterifying polyglycerol-2, a polymer of plant-derived glycerol, with tetraisostearic acid, a branched-chain fatty acid obtained from vegetable oils like olive or rapeseed. This results in a viscous, non-polar liquid suited for oil-based formulations. Commonly found in lipsticks, anhydrous balms, color cosmetics, and some emulsions, it acts as a texture enhancer by increasing viscosity and providing a non-greasy slip. As an emollient, it lubricates skin surfaces; as a surfactant, it reduces interfacial tension; and as an emulsifier, it stabilizes oil-in-water or water-in-oil systems, ensuring product uniformity and preventing phase separation during storage or 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

Provides a smooth, cushioned feel to products like lip balms and creams.

Supports stable blending of oils and water for even application.

Helps maintain product consistency without greasiness.
