What Is Polyglyceryl-4 Oleate?
Polyglyceryl-4 oleate, also known as polyglyceryl oleate, is an emulsifying and skin conditioning ingredient used in skin care products. It’s the ester of oleic acid, an omega-9 fatty acid, and polyglycerin-4, a glycerin-based polymer.
As an emulsifying agent, polyglyceryl-4 oleate works to mix oil and water-based ingredients, creating smoother, homogenous formulas. Although primarily used in skin care applications as an emulsifier, this ingredient also hydrates skin through its light emollient properties.
This multi-tasking ingredient appears as a yellow-to-amber liquid in its raw material state and is most often used in leave-on applications, like moisturizers, in concentration between 2-10%.
The Cosmetic Ingredient Review (CIR) Expert Panel reviewed polyglyceryl-4 oleate and consider it safe for use in cosmetics.
