Science
Mechanism of Action
As a surfactant, PPG-2-DECETH-3 efficiently lowers the surface tension within formulations. This action allows it to emulsify oil and water phases, preventing separation, and facilitates the effective dispersion and removal of oils and environmental contaminants from the skin's surface during cleansing.

Stability
The optimal pH range for the stability of PPG-2-DECETH-3 is currently unknown. Formulators must consider the potential presence of residual starting materials, such as ethylene oxide and propylene oxide, and the possible formation of 1,4-dioxane, which are common concerns for alkyl PEG/PPG ethers. Additionally, this ingredient may act as a penetration enhancer, influencing the absorption of other active compounds.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PPG-2-DECETH-3, as part of the broader group of 131 alkyl PEG/PPG ethers, is safe for use in cosmetic practices when formulated to be non-irritating. A specific maximum concentration for PPG-2-DECETH-3 has not been identified. However, related compounds like PPG-2 methyl ether, PPG-3 methyl ether, and PPG-2 methyl ether acetate are typically used within a concentration range of 0.4% to 2%. No specific SCCS opinion or FDA status for this ingredient was found.
