PEG-4 OLEATE.

Valuable CAS 9004-96-0 / SURFACTANT - EMULSIFYING

PEG-4 Oleate is a polyethylene glycol (PEG) derivative primarily utilized as an emulsifier, enabling the stable incorporation of oil and water phases within cosmetic formulations. Beyond its emulsifying capabilities, it functions as a solvent and solubilizer for various cosmetic ingredients, contributing to product consistency and efficacy.

Science

Mechanism of Action

PEG-4 Oleate operates as a surfactant by significantly reducing the interfacial tension between immiscible substances, allowing for the creation and stabilization of emulsions. As a liquid PEG derivative, it effectively solubilizes lipophilic (oil-soluble) cosmetic components, ensuring their uniform dispersion. Furthermore, it possesses humectant and skin-conditioning properties, which can contribute to hydration and a smooth skin feel.

The Cosmetic Ingredient Review (CIR) Expert Panel has determined PEG-4, which includes PEG-4 Oleate, to be safe for use in cosmetic applications. It is important to note that some PEGs can enhance the dermal penetration of other ingredients. Formulators are advised to ensure that products containing alkyl PEG ethers, such as PEG-4 Oleate, are non-irritating and should not be applied to compromised skin. Manufacturers are also responsible for verifying the removal of potential impurities, specifically ethylene oxide and 1,4-dioxane.
