Fluorocarbon dermal protective compositions

Claim 1

In a dermal protective composition comprising a pharmaceutical extending medium and a protective amount of a fluorocarbon-containing active ingredient, the improvement comprising employing as said active ingredient a substantive dermally non-irritating compound of the formula ##STR92## wherein A is a polyvalent saturated or unsaturated, aliphatic or cycloaliphatic organic radical containing 8 to 108 carbon atoms; Z' is --NH-- or --O--; X is --(W) d R f where W is a bridging group free of isocyanate or isocyanate reactive groups, d is a zero or one, and R f is a fluorinated, saturated, monovalent, aliphatic radical containing 3 to 20 carbon atoms in which the carbon atoms of the chain are substituted only by fluorine, chlorine or hydrogen atoms with no more than one hydrogen or chlorine atom for every two carbon atoms and the terminal carbon atom is perfluorinated, and in which a divalent oxygen or trivalent nitrogen atom, bonded only to carbon atoms can be present in the skeletal chain; Y is --H, M e + , or R 1 where R 1 is an aliphatic, cycloaliphatic or aromatic radical containing 1 to 24 carbon atoms; M e + is a pharmaceutically acceptable organic or inorganic cation and e is one, two or three; n is an integer from 1 to 10 designating the same or different ##STR93## n' is zero or an integer from 1 to 9 designating the same or different ##STR94## n+n' = 2- 10; said compound containing from 1 to 60 percent by weight of fluorine.
