Perfluorononylethyl Stearyl Dimethicone
What is Perfluorononylethyl Stearyl Dimethicone?
Perfluorononylethyl Stearyl Dimethicone is a synthetic fluorosilicone compound, consisting of a perfluorinated nonyl ethyl chain linked to stearyl-modified dimethicone. This hybrid structure combines silicone's emolliency with fluorocarbon's low surface tension and repellency. Commonly found in long-wear foundations, lipsticks, sunscreens, and hair products, it spreads evenly due to its fluid nature. In formulations, it creates an occlusive yet breathable film that repels water, oils, and sweat, extending makeup durability and enhancing shine without stickiness. As a conditioning agent, it deposits a lightweight layer that softens skin texture and improves flexibility by mimicking natural lipids. Its compatibility with pigments ensures vibrant, uniform color payoff in decorative cosmetics.
