Perfluorononyl Dimethicone

What is Perfluorononyl Dimethicone?

Perfluorononyl dimethicone is a synthetic fluorosilicone polymer created by attaching perfluorinated nonyl groups to a polydimethylsiloxane backbone. This structure combines silicone's emollient properties with fluorocarbon's extreme hydrophobicity and low surface tension. Primarily used in color cosmetics like foundations, primers, and mascaras, as well as skincare serums and lotions, it functions by spreading evenly across the skin to form a lightweight, breathable film. This film enhances slip, allowing products to glide effortlessly without tugging, while providing a barrier that resists water, oils, and friction for prolonged wear. Its unique chemistry reduces tackiness in formulations, contributing to a velvety, non-greasy finish that maintains skin's supple texture during application.
