Science
Mechanism of Action
This ingredient's molecular structure incorporates both oil-attracting (lipophilic) and water-attracting (hydrophilic) components. This unique design allows it to significantly lower the interfacial tension between immiscible phases, thereby facilitating the creation of stable emulsions of oil and water and acting as an effective solvent for various substances within a formulation.

Stability
This ingredient, like other polypropylene glycols and their derivatives, exhibits remarkable stability across a wide pH spectrum, including acidic, neutral, and alkaline conditions. It also maintains its integrity and function in the presence of hard water and in both oxidizing and reducing environments.
Safety
Safety Profile
The CIR Expert Panel, in their 2013 review of Alkyl PEG/PPG Ethers, concluded that PPG-1-ISODECETH-7 is safe for cosmetic use under current practices and concentrations, provided formulations are designed to be non-irritating. The panel noted that its larger molecular size likely limits skin penetration. Concerns regarding potential residual impurities (ethylene oxide, propylene oxide, 1,4-dioxane) and its role as a penetration enhancer were addressed in the comprehensive CIR report. Specific SCCS opinions or FDA statuses are not identified, though related glycols are generally recognized as safe.
