Trideceth-10

What is Trideceth-10?

Trideceth-10 is a synthetic nonionic surfactant produced by ethoxylating tridecyl alcohol with ten molecules of ethylene oxide. This process creates a molecule with a hydrophobic alkyl chain and hydrophilic polyether head, ideal for cosmetic formulations. Commonly found in shampoos, body washes, facial cleansers, and emulsified products like creams and lotions, it functions by reducing surface tension between water, oils, and dirt. This allows effective removal of impurities during cleansing while enabling stable mixtures of immiscible phases in emulsions. Its balanced hydrophile-lipophile properties contribute to mild foaming and improved product texture without stripping natural oils excessively.

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

Provides gentle cleansing by effectively removing dirt and oils.

Stabilizes emulsions for smooth, consistent lotion and cream textures.

Supports mild foaming action in shampoos and body washes.
