Treatment of perfluoro-N-fluoropiperidine and perfluoro-N-fluoromorpholine with manganese pentacarbonyl hydride converts them into perfluoropiperidine and perfluoromorpholine, respectively. Perfluoromorpholine reacts with fuming nitric acid in trifluoroacetic anhydride to give perfluoro-N-nitromorpholine, and with anhydrous potassium fluoride to yield perfluoro-5,6-dihydro-2H-1,4-oxazine; thermal chlorination
The present invention relates to the use of polyamide particles as anti-irritant agents for reducing or eliminating the irritant effect of one or more compounds with an irritant effect, preferably in a cosmetic or dermatological composition.
