Science
Mechanism of Action
This ingredient functions across several key areas to optimize cosmetic formulations and skin condition. As an emollient, it softens and smooths the skin by forming a protective layer. In its role as an emulsifier and surfactant, it effectively lowers the interfacial tension between immiscible liquids, such as oil and water, allowing them to mix uniformly and creating stable emulsions. This property also aids in the cleansing process and ensures the even distribution of cosmetic products on the skin. Furthermore, it serves as a skin conditioning agent, contributing to the overall well-being and maintenance of healthy skin.

Stability
Polypropylene glycols (PPGs) and their derivatives, including PPG-1 TRIDECETH-13, are known for their broad range of viscosity and solubility characteristics, making them adaptable for diverse formulations. Liquid PPGs can also serve as effective solubilizers and solvents.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PPG-1 TRIDECETH-13, as part of a group of alkyl PEG/PPG ethers, is safe for use in cosmetic formulations, provided the finished product is formulated to be non-irritating. While not reported in current use at the time of the 2013 CIR review, its future application is expected at concentrations comparable to other ingredients in its class (e.g., up to 10% for PPG-5-ceteth-20 in leave-on products). There is no specific SCCS opinion available for this ingredient, and in the U.S., cosmetic ingredients do not require FDA approval prior to market entry, with the exception of color additives.
