Abstract

A method for treating phytophotodermatitis including the steps of applying an isothiocyanate functional surfactant to an area affected by phytophotodermatitis, wherein said isothiocyanate functional surfactant comprises at least one isothiocyanate functional group associated with an aliphatic and/or aromatic carbon atom of the isothiocyanate functional surfactant.

Claims (8)

1. A method for treating phytophotodermatitis with an isothiocyanate functional surfactant, comprising the step(s) of:

applying a surfactant or a pharmaceutically acceptable salt thereof to an area affected by phytophotodermatitis, wherein the protonated form of said surfactant is represented by the following chemical structure:

wherein R 1 is selected from the group consisting of an alkyl, aryl, and alkenyl group containing 1 to 25 carbon atom(s); wherein R 2 is selected from the group consisting of NCS; and wherein R 3 -R 5 are each independently selected from the group consisting of H; OH; and an alkyl, aryl, alkaryl, aralkyl, alkoxy, alkanoyl, aroyl, and alkenyl group containing 1 to 25 carbon atom(s) with the proviso that at least one of R 3 -R 5 is selected from the group consisting of an alkyl, aryl, alkaryl, aralkyl, alkoxy, alkanoyl, aroyl, and alkenyl, group containing 8 to 25 carbon atoms.

2. A method for treating phytophotodermatitis with an isothiocyanate functional surfactant, comprising the step(s) of:

applying a surfactant or a pharmaceutically acceptable salt thereof to an area affected by phytophotodermatitis, wherein the surfactant is represented by the following chemical structure:

wherein R 1 is selected from the group consisting of an alkyl, aryl, and alkenyl group containing 1 to 25 carbon atom(s); wherein R 2 is selected from the group consisting of NCS; and wherein R 3 -R 5 are each independently selected from the group consisting of H; OH; and an alkyl, aryl, alkaryl, aralkyl, alkoxy, alkanoyl, aroyl, and alkenyl group containing 1 to 25 carbon atom(s) with the proviso that at least one of R 3 -R 5 is selected from the group consisting of an alkyl, aryl, alkaryl, aralkyl, alkoxy, alkanoyl, aroyl, and alkenyl, group containing 8 to 25 carbon atoms; and wherein X comprises a counter cation.

3. The method according to claim 1 , further comprising the step of applying an additional surfactant, wherein the additional surfactant is selected from at least one of the group comprising a non-ionic surfactant, an anionic surfactant, a cationic surfactant, a zwitterionic surfactant, and combinations thereof.

4. The method according to claim 2 , further comprising the step of applying an additional surfactant, wherein the additional surfactant is selected from at least one of the group comprising a non-ionic surfactant, an anionic surfactant, a cationic surfactant, a zwitterionic surfactant, and combinations thereof.
