Perfluoropolyether Special Additives for Cosmetics: A New Solution for Long-Lasting Skin Care "Liquid Glove"

Perfluoro Polyether (PFPE) is a type of perfluorinated polymer whose main molecular chain is entirely composed of carbon, oxygen and fluorine elements. The bond energy of carbon-fluorine bond reaches 485 kJ/mol, much higher than 413 kJ/mol of carbon-hydrogen bond. Therefore, PFPE features excellent chemical and thermal stability, and is insoluble in water as well as most organic solvents. In recent years, PFPE has attracted extensive attention in the cosmetics industry thanks to its colorless, odorless, transparent, non-toxic and non-irritating properties, and has become a key functional ingredient in high-end skin care and makeup formulations.

This series of PFPE special additives are tailor-made for high-end cosmetic formulations, available in three grades: low viscosity, medium viscosity and high viscosity, fully meeting the demands of various scenarios ranging from lightweight facial oils to high-adhesion care products. The products are colorless, transparent, odorless and non-irritating. After application, they spread rapidly to form a film on the skin surface, combining hydrophobicity, oleophobicity and air permeability without causing stuffiness, hence known as the "liquid glove" in the industry.

The low viscosity grade spreads fast and delivers a lightweight skin feel, suitable for facial oils, sunscreens and other products requiring rapid film formation, and can maintain protective effects even during sweating or swimming. The medium viscosity grade balances spreadability and adhesion, ideal for paste formulations such as hair creams and eye shadow creams. The high viscosity grade offers superior film durability, perfect for skin care products that require long-lasting protection. For cosmetic formulators, the adjustable viscosity of PFPE enables flexible adaptation to different textures and functional requirements, solving the common formulation dilemma of traditional oil-based ingredients that struggle to achieve both long-lasting performance and lightweight skin feel.
