Polyglyceryl-6 Octastearate

What is Polyglyceryl-6 Octastearate?

Polyglyceryl-6 octastearate is a polyglyceryl ester created by linking six glycerol units into polyglycerol-6 and esterifying with eight stearic acid molecules, a fatty acid sourced from plant oils like coconut or palm. This structure yields a balanced hydrophilic-lipophilic profile ideal for non-ionic surfactants. Primarily used in skincare emulsions such as moisturizers, lotions, foundations, and cleansers, it functions by lowering interfacial tension between oil and water, forming protective films that prevent phase separation for consistent product texture. As an emollient, it lubricates the skin surface, enhancing slip and reducing friction during application. Its mild, biodegradable nature makes it suitable for daily-use cosmetics, contributing to smooth, non-greasy finishes without heavy residue.

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

Softens skin by filling surface imperfections and improving texture.

Stabilizes emulsions in creams and lotions for even consistency.

Aids gentle cleansing as a surfactant in washes and micellar products.

Who It's For
