Abstract:
A method for using a medication as a skin remedy comprising administering a composition which comprises an aqueous emulsion of at least one semifluorinated alkane of the general formulaRFRH or RFRHRF wherein RF is a linear or branched perfluoralkyl group and RH is a linear or branched, saturated alkyl group, wherein the linear semifluorinated alkane has the formula:F(CF2)n(CH2)mH or F(CF2)n(CH2)m(CF2)nF, the branched semifluorinated alkane includes within the perfluoralkyl groups â€”FCXâ€” units where X=C2F5, C3F7 or C4F9 and within the alkyl groups â€”HCYâ€” units where Y=C2H5, C3H7 or C4H9, contained within a perfluoralkyl chain is a â€”CX2â€” group and contained within an alkyl chain is a â€”CY2â€” group, and wherein further the total number of the carbon atoms in the perfluoralkyl part is between 1 and 20, and in the alkyl part the number of the carbon atoms is between 3 and 20.
