Fluorinated ingredients: ELC Management LLC published cosmetic compositions with perfluorinated ingredients.¹⁷ The described invention comprises at least one perfluorinated component and at least one aromatic component in which the amount of aromatic component is sufficient to compatibilize the fluorinated component in the cosmetic composition. Transfer-resistant, long-wearing or other types of cosmetic or pharmaceutical compositions containing the components and a method for matching a fluorinated component in a cosmetic composition using an aromatic component are given. Also provided are cosmetic compositions containing at least one perfluorinated amide. For example, one lipstick composition contains N-octylperfluorononamide, ethylhexyl methoxycinnamate, octocrylene and other ingredients.

Polyfluoroalkyl dimethicone polymer: Combe Inc. created pre-shave preparations with enhanced lubricity formulated with polyfluoroalkyl dimethicone polymer.¹⁸ The pre-shave composition disclosed included at least one polyfluoroalkyl dimethicone polymer, a volatile component to serve as a carrier to the polyfluoroalkyl dimethicone polymer, and a suspending agent to suspend the polyfluoroalkyl dimethicone polymer in the volatile component.
