Abstract

An isothiocyanate functional surfactant, wherein the protonated form of said surfactant is represented by the following chemical structure: wherein X includes an integer ranging from approximately 1 to approximately 25, and wherein Y includes an integer ranging from approximately 6 to approximately 25.

Claims (11)

1. An isothiocyanate functional surfactant, comprising:

a surfactant or a pharmaceutically acceptable salt thereof, 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 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, and alkanoyl 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, and alkanoyl, group containing 8 to 25 carbon atoms.

2. An isothiocyanate functional surfactant, comprising:

a surfactant or a pharmaceutically acceptable salt thereof, wherein the protonated form of said surfactant is represented by the following chemical structure:

wherein X comprises an integer ranging from 1 to 25, and wherein Y comprises an integer ranging from 6 to 25.

3. An isothiocyanate functional surfactant, comprising:

a surfactant or a pharmaceutically acceptable salt thereof, wherein the protonated form of said surfactant is represented by the following chemical structure:

4. An isothiocyanate functional surfactant, comprising:

a surfactant or a pharmaceutically acceptable salt thereof, wherein the surfactant is represented by the following chemical structure:

wherein R 1 is selected from the group consisting of an alkyl 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, and alkanoyl 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, and alkanoyl, group containing 8 to 25 carbon atoms; and wherein X comprises a counter cation.
