Ceteareth-22

What is Ceteareth-22?

Ceteareth-22 belongs to the ceteareth family of ingredients, chemically known as polyoxyethylene (22) cetyl ether. It originates from cetyl alcohol, typically derived from natural fats like coconut or palm oil, which undergoes ethoxylation—a process adding ethylene oxide chains to enhance solubility and functionality. This results in a waxy, water-dispersible compound commonly used in rinse-off and leave-on cosmetics such as body washes, moisturizers, and hair conditioners. In formulations, it works by lowering surface tension to mix oil and water phases seamlessly, forming stable emulsions that prevent separation. It also boosts foam in cleansers and adjusts flow properties for a pleasant texture, making products easier to spread and rinse.

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.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Supports creation of uniform lotions and creams with lasting stability.

Aids in producing gentle foams for effective cleansing in washes.

Enhances thickness for better product application and feel.
