Science
Mechanism of Action
This ingredient functions through multiple pathways: primarily as a non-ionic surfactant, it lowers surface tension; as an emulsifier, it stabilizes immiscible phases like oil and water. Its polymeric structure effectively increases the viscosity of liquid formulations, serving as a rheology modifier. Furthermore, it delivers skin conditioning benefits by forming a subtle film on the skin's surface, contributing to emolience, and is notable for its capacity to attenuate the irritancy profiles of co-surfactants. Its high molecular mass inherently limits penetration into healthy skin.

Safety
Safety Profile
The CIR Expert Panel concluded that the group of ingredients including PEG-120 Methyl Glucose Trioleate is safe in current cosmetic uses and concentrations. While one study indicated slight irritation to rabbit skin, it was concurrently classified as a non-sensitizer in a guinea pig maximization test. Potential concerns regarding impurities like ethylene oxide and 1,4-dioxane, which are typically associated with ethoxylated compounds, have been noted. The U.S. FDA has also designated this ingredient as safe for general or specific, limited use in food.
