Fomblins are non-greasy, transparent, liquid polymers. They are fluorinated, meaning hydrogen atoms are replaced with fluorine atoms. They are hydrophobic and lipophobic, protecting the skin against external damaging influences and acting as a protective shield against environmental impacts, giving the product a "velvet effect."
Perfluoropolymethylisopropyl ether (Fomblin HC) showed excellent results in treating irritation and non-allergic contact dermatitis among workers handling aggressive chemicals such as paint solvents, surfactants, and lubricants, as well as metal powders.
Polyperfluoromethylisopropyl Ether has also been tested in a lipstick where it forms a protective film against environmental damaging factors. Lipstick was long-wearing and comfortable to use, and it showed good protective performance with a good sensory profile.
Several barrier creams containing perfluoropolyethers were tested for safety and comedogenic properties. The study confirmed that fomblins are non-comedogenic, non-mutagenic, non-toxic, non-irritating, and generally safe for use in skincare formulations.
