What is it?
Polyglyceryl-4 Oleate is a multifunctional ingredient used in skincare products, known for its emulsifying and moisturizing properties. It is derived from the esterification of polyglyceryl-4 (a compound made by linking four glycerin molecules) with oleic acid, a fatty acid commonly found in vegetable oils. This combination enhances the properties of both glycerin and oleic acid, resulting in a compound that can effectively blend liquid and oil-based ingredients while providing hydration and skin barrier support.
Where does it come from?
Polyglyceryl-4 Oleate is sourced from natural ingredients, obtained from plant oils such as soybean, palm, and coconut oil. Oleic acid is also derived from natural sources, primarily from oils like olive oil, sunflower oil, and avocado oil. The synthesis process involves the esterification of polyglyceryl-4 with oleic acid, creating a compound that harnesses the benefits of both components for use in skincare formulations.
Polyglyceryl-4 Oleate → 4 glycerin units + oleic acid and Polyglyceryl-6 Oleate → 6 glycerin units + oleic acid
