Science
Mechanism of Action
This ingredient operates through several mechanisms: as an emollient, it imparts a soft, smooth tactile sensation to the skin and aids in maintaining hydration levels. Its solvent capabilities facilitate the uniform dispersion of other active components within a formulation. As a non-ionic surfactant, it effectively lowers surface tension, which is crucial for creating stable emulsions by blending immiscible oil and water phases, and also assists in cleansing the skin by emulsifying and removing impurities. Furthermore, it acts as a penetrant, enhancing the absorption and deeper delivery of active ingredients into the skin or other substrates.

Safety
Safety Profile
The CIR Expert Panel concluded that PPG-9 ETHYLHEXETH-5, along with 130 other alkyl PEG/PPG ethers, is safe for use in cosmetics under current practices and concentrations, provided the final formulation is non-irritating. The typical maximum use concentration for alkyl PEG/PPG ethers is generally lower than for alkyl PEG ethers or PPGs alone.
