What it is
Polyglyceryl-3 oleate is formed by esterifying triglycerin with oleic acid, producing a nonionic surfactant with mild, skin-friendly properties. In sunscreens it is used to emulsify oil and water phases and to disperse pigments, while also adding a soft, conditioned feel. Its nonionic nature makes it compatible with a wide range of other ingredients.
Safety & warnings
Polyglyceryl oleate esters are generally regarded as mild and well tolerated, and nonionic emulsifiers of this kind have low irritation potential. Because it is derived from oleic acid, some formulators consider oleate esters as having modest comedogenic potential in very acne-prone users, though tolerance varies and it is widely used in facial products. It is not a fragrance allergen.
Origin & sourcing
Synthetic ester made from glycerin and oleic acid, both of which are commonly plant-derived.
