Science

Mechanism of Action

TRIDECETH-7 acts as a surfactant by reducing the surface tension of liquids, facilitating the mixing of oil and water for effective cleansing. As an emulsifier, it creates stable dispersions, preventing the separation of oil and water-based components. It also solubilizes non-water-soluble ingredients and provides emollient properties, contributing to the softness and smoothness of skin and hair.

Safe as used with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel deemed alkyl PEG ethers, including Trideceth-7, safe for cosmetic use when formulated to be non-irritating. The FDA permits its use as an indirect food additive. Formulations should account for potential 1,4-dioxane contamination, a byproduct of ethoxylation, which is controllable through purification processes.
