Polyethylene Glycol Cetyl Ether丨CAS 9004-95-9

Polyethylene Glycol Cetyl Ether is widely used in personal care, cosmetic, pharmaceutical, and industrial formulations as a nonionic surfactant, emulsifier, and solubilizing agent. In cosmetics and skincare, it is incorporated into creams, lotions, hair conditioners, and cleansers to stabilize emulsions, improve texture, and enhance the spreadability of products. In pharmaceuticals, it serves as a solubilizer and stabilizer for active ingredients in topical, oral, and parenteral formulations. The compound is also employed in industrial applications such as detergents, lubricants, and coatings, where it helps to improve wetting, dispersion, and emulsification. Additionally, it is used in research to study surfactant behavior, micelle formation, and formulation stability.

Polyethylene Glycol Cetyl Ether offers several advantages that make it valuable across personal care, pharmaceutical, and industrial applications. Its nonionic nature provides effective emulsification and solubilization over a broad pH range and in various solvent systems. The PEG chain improves water solubility, while the cetyl group enhances hydrophobic interaction, enabling efficient stabilization of oil-in-water or water-in-oil emulsions. It is generally mild to skin and hair, making it suitable for personal care formulations. Its chemical stability, compatibility with other ingredients, and versatility in functional roles allow consistent performance, reproducibility, and formulation flexibility.
