Mechanism of Action
Functioning as an amphiphilic emulsifying surfactant, PEG-150 DIOLEATE contains distinct hydrophilic polyethylene glycol segments and lipophilic oleic acid chains. This dual nature allows it to significantly reduce the surface tension between immiscible oil and water phases, thereby enabling their uniform dispersion and preventing phase separation to form stable emulsions. Furthermore, it acts as a viscosity-controlling agent and thickener; when solubilized in the aqueous phase, its extensive molecular chains entangle with water molecules and other ingredients, precisely increasing the overall viscosity and contributing to a consistent, elegant texture.

Stability
Polyethylene glycols and their derivatives are recognized for excellent skin tolerance and a broad spectrum of viscosity and solubility properties. It is observed that water solubility generally decreases with increasing molar mass.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded PEG-150 DIOLEATE is safe for cosmetic use when formulated to be non-irritating. Crucially, the panel highlighted concerns regarding potential impurities such as 1,4-dioxane and ethylene oxide, emphasizing the necessity for manufacturers to adhere to current good manufacturing practices (cGMPs) to minimize these contaminants. Due to its higher molecular weight, PEG-150 DIOLEATE exhibits a reduced likelihood of skin absorption compared to lower molecular weight polyethylene glycols.
