Science
Mechanism of Action
This ingredient functions by providing deep hydration as an emollient, helping to soften the skin's texture. As an emulsifier, it plays a critical role in stabilizing formulations by uniformly dispersing immiscible oil and water components. Aligning with other polyethylene glycols, it enhances skin moisture retention through hydrogen bonding with water molecules, which facilitates gradual hydration delivery and reduces transepidermal water loss.

Safety Profile
While the Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed PEG-3 TRIMETHYLOLPROPANE TRIISOSTEARATE, general polyethylene glycols (PEGs) are widely considered safe for cosmetic use. However, vigilance is advised to ensure product purity, as potential contamination by toxic impurities like 1,4-dioxane and ethylene oxide can occur, necessitating adherence to current Good Manufacturing Practices (cGMPs). Rare instances of hypersensitivity reactions have been observed with general PEG compounds.
