Science
Mechanism of Action
This ingredient functions by significantly lowering the interfacial tension between immiscible liquid phases, which enables the stable mixing of oil and water to form emulsions. On the skin, it can create a film that aids in the removal of dirt and impurities, acting as a cleansing agent, and also offers conditioning benefits.

Stability
Polypropylene glycols and their derivatives typically exhibit a wide array of viscosity and solubility characteristics. Formulators must diligently monitor for the presence of residual starting materials like ethylene oxide and propylene oxide, as well as the by-product 1,4-dioxane. This ingredient may also enhance the penetration of other substances.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed alkyl PEG/PPG ethers, including PPG-2-DECETH-50, safe for use in cosmetic applications, provided formulations are non-irritating. The maximum permissible concentration for these ethers is generally lower than for alkyl PEG ethers or PPGs alone. Vigilance is required to monitor potential residual by-products, specifically ethylene oxide, propylene oxide, and 1,4-dioxane. No specific safety status from SCCS or FDA was found.
