Polyglyceryl-3 Caprylate

What is Polyglyceryl-3 Caprylate?

Polyglyceryl-3 Caprylate is a bio-based ingredient formed by esterifying polyglycerol-3, derived from vegetable glycerin, with caprylic acid sourced from coconut or palm kernel oils. This creates a non-ionic surfactant commonly used in natural and organic cosmetics, particularly in cleansers, shampoos, lotions, and micellar waters. It works by lowering surface tension between oil and water, promoting effective dirt removal and foam formation during cleansing. As an emulsifier, it forms a protective film at the interface of immiscible phases, ensuring product stability and smooth texture without separation. Valued for its mildness and biodegradability, it serves as a PEG-free alternative in formulations targeting sensitive skin applications.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

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

Supports gentle cleansing by reducing surface tension for effective yet non-stripping wash-off.

Stabilizes emulsions in creams and lotions for consistent application and feel.

Compatible with natural formulations as a biodegradable, mild functional agent.

Who It's For
