What is Ceteth-20?

Ceteth-20 is a synthetic non-ionic surfactant produced by ethoxylating cetyl alcohol, a fatty alcohol from natural sources like coconut or palm, with 20 units of ethylene oxide. This creates a hydrophilic molecule ideal for cosmetic applications in cleansers, shampoos, conditioners, lotions, and micellar waters. It works by lowering surface tension to blend immiscible oil and water phases, forming stable emulsions with smooth textures. As a solubilizer, it disperses oils and scents evenly in aqueous formulas for clarity. In cleansing products, it forms micelles that encapsulate and rinse away impurities softly. Its versatile functionality supports foaming, wetting, and conditioning in hair and skin care, enhancing overall product performance and mildness.

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.
Cleansing agent
Removes dirt, oil, and impurities by lowering surface tension and forming micelles, enabling soils to be lifted and rinsed away from skin, hair, or teeth.
Solubilizing agent
Helps incorporate oils and fragrance into water-based formulas by forming micro-solutions, enabling clear sprays, toners, and micellar products.
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 and hair for a smoother feel.

Facilitates gentle cleansing by lifting dirt and oils.

Stabilizes emulsions for consistent lotion and cream textures.
