Science
Mechanism of Action
As a surfactant, PEG-120 Distearate reduces the surface tension between immiscible liquids, allowing water to effectively mix with oils and dirt for improved cleansing and rinsing from skin and hair. Its emulsifying properties stabilize oil-in-water or water-in-oil formulations, preventing phase separation and aiding in the dissolution of other ingredients within a solvent system.

Stability
Polyethylene glycol distearate can be melted by heating to 60°C, often with other surfactants, before being incorporated into the water phase at approximately 35°C. These polyethylene glycols are generally well-tolerated by the skin and exhibit resistance to microbiological degradation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEG-120 Distearate is safe for use in cosmetic applications. While specific maximum concentration data were not extensively documented, its overall safety is affirmed. Manufacturers can control the presence of trace amounts of 1,4-dioxane, a potential by-product of the ethoxylation process, through purification steps.
