Mechanism of Action
This ingredient operates as a surfactant by reducing interfacial tension between immiscible liquids, thereby stabilizing oil and water mixtures as an emulsifier. As a cleansing agent, it lowers surface tension to effectively dislodge and remove dirt and impurities from skin and hair. Its polypropylene glycol derivative structure also imparts skin conditioning benefits and aids in the solubilization of other formulation components.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PPG-2-DECETH-20, along with 130 other alkyl PEG/PPG ethers, is safe for use in cosmetic formulations, provided the final product is non-irritating. While no specific maximum concentration was provided for PPG-2-DECETH-20, the assessment covers 'present practices of use and concentration.' Formulators should be mindful of potential impurities like ethylene oxide and 1,4-dioxane, which are considered carcinogenic by-products of the ethoxylation process and whose presence depends on the compound's purity.
