Polyglyceryl-10 Heptahydroxystearate

What is Polyglyceryl-10 Heptahydroxystearate?

Polyglyceryl-10 Heptahydroxystearate is a non-ionic surfactant created through the esterification of polyglycerol-10, a polymer of glycerol, with heptahydroxystearic acid, a hydroxylated fatty acid obtained from hydrogenated castor oil. This structure gives it hydrophilic and lipophilic properties, making it ideal for oil-in-water emulsions. Typically used in cleansers, moisturizers, makeup removers, and hair care products, it functions by lowering surface tension at the oil-water boundary to form stable micelles and emulsions, preventing separation and ensuring even distribution of ingredients. Its multiple hydroxyl groups contribute to humectant activity, binding water molecules, while its surfactant nature enables gentle foaming and dispersion. As a skin conditioner, it helps maintain barrier integrity and softness. Being biodegradable and free from ethoxylation, it suits formulations targeting sensitive or eco-conscious users.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Humectant

Attracts and holds water in the stratum corneum, boosting hydration and plumpness; commonly used in moisturizers, cleansers, and hair conditioners.

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

Draws moisture to the skin surface for improved hydration.

Creates stable blends of oil and water for smooth product textures.

Supports mild cleansing and conditioning without harshness.
