Science
Mechanism of Action
This ingredient functions primarily in two ways: as an emollient and as a surfactant. As an emollient, it forms a protective barrier on the skin's surface, contributing to a smoother, cleaner, and more hydrated feel. As a surfactant, it reduces the surface tension between different phases of a formulation, facilitating the even dispersion of ingredients and promoting product stability.

Safety Profile
The CIR Expert Panel concluded that PPG-1-Ceteth-1, along with other alkyl PEG/PPG ethers (and PPGs ≥3), is safe when used in cosmetic formulations that are designed to be non-irritating. Concerns regarding potential contamination with 1,4-dioxane and ethylene oxide during manufacturing necessitate minimization through proper filtration and purification.
