Polyglyceryl-4 olivate is the plant-derived or synthetic (Paula’s Choice uses the former) ester of olive oil and polyglycerin, which is, as the name implies, a polymer made from glycerin. It’s a multitalented ingredient that in cosmetics can work as an emulsifier, stabilizer, emollient, and even a surfactant (cleansing agent).
Polyglyceryl-4 olivate is considered non-sensitizing and is safe for use in cosmetics. The olive oil portion is a good source of beneficial fatty acids and phenolic compounds which work as antioxidants.
