What is Polyglyceryl-10 Tristearate?

Polyglyceryl-10 Tristearate is a multi-ester compound formed by linking decaglycerol—a chain of 10 glycerol molecules—with three stearic acid chains, typically sourced from vegetable oils like palm or coconut. This non-ionic ingredient belongs to the polyglyceryl ester family, widely used in skincare for its versatile functionality. In cosmetic products such as lotions, creams, and gentle cleansers, it acts by lowering surface tension between oil and water phases, creating stable emulsions with smooth textures. As an emollient, it coats the skin to enhance slip and reduce roughness, while its surfactant properties aid in mild foaming and dirt removal during cleansing. Its skin-conditioning action helps maintain hydration barriers indirectly by improving product spreadability and compatibility.

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.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.

Benefits

Provides softening effect by smoothing skin's surface and improving texture.

Supports emulsion stability for even application in creams and lotions.

Aids gentle cleansing as a mild surfactant without pore-clogging potential.
