Polyglyceryl-4 Oleate

What Polyglyceryl-4 Oleate is & what it does

Polyglyceryl-4 Oleate is a non-ionic emulsifier and surfactant formed from oleic acid (a fatty acid) and polyglycerin. In creams, lotions, and sunscreens it helps disperse oils and stabilize the emulsion, and it can also act as a mild cleansing and solubilizing agent. It is valued in gentle, PEG-free formulations for its skin-friendly, low-irritation profile.

Is Polyglyceryl-4 Oleate safe?

Polyglyceryl-4 Oleate is a non-ionic emulsifier and surfactant widely used in cosmetics and generally regarded as mild and well tolerated. It is common in gentle, PEG-free cleansers, creams, and sunscreens. People with very sensitive skin should patch test a new product as a precaution.

Is Polyglyceryl-4 Oleate comedogenic?

Polyglyceryl-4 Oleate is derived from oleic acid, and because oleic acid is sometimes associated with pore-clogging, very acne-prone users may want to monitor how their skin responds. As a finished emulsifier it is usually present at modest levels, and reactions vary by individual and full formula. Whether a product clogs pores cannot be judged from this ingredient alone.

Is Polyglyceryl-4 Oleate vegan?

Polyglyceryl-4 Oleate is made from glycerin and oleic acid, which can be sourced from plants or animals. Many cosmetic-grade versions use plant-derived oils, making vegan options available. Confirm with the brand if vegan sourcing is important, since the INCI name does not specify the origin.
