What Is Polyglyceryl-6 Oleate?
Polyglyceryl-6 oleate is a versatile ingredient whose emollient properties provide hydration and also assist with cleansing. It’s made from an ester of the fatty acid oleic acid combined with a polymer of glycerin known as polyglycerin-6.
Being made from both water- and oil-soluble ingredients, allows it to work in different types of emulsions. It is most often used to assist other emulsifiers and surfactants and is noted for its hydrating abilities.
Polyglyceryl-6 oleate’s safety has been evaluated although as of this writing a final safety assessment hasn’t been issued. Usage levels in cosmetics range from 1–5% whether the product is meant to be left on skin or rinsed.
This ingredient may be animal or plant-derived or also made synthetically.
