Abstract

Claims (23)

1 . A liquid medium, comprising:

water; and

a compound of Formula I:

wherein R 1 and R 2 may be the same or different, and comprise at least one group selected from the group consisting of C 1 -C 6 alkyl, optionally the C 1 -C 6 alkyl may include one or more of oxygen, nitrogen, or sulfur atoms or groups that include at least one of these atoms, and the alkyl chain may be optionally substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;

n is an integer from 3 to 12;

the terminal nitrogen is optionally further substituted with R 3 , wherein R 3 is selected from the group consisting of hydrogen, oxygen, hydroxyl, and C 1 -C 6 alkyl; and

an optional counterion associated with the compound which, if present, is selected from the group consisting of chloride, bromide, and iodide.

2 . The liquid medium of claim 1 , wherein R 1 and R 2 are methyl.

3 . The liquid medium of claim 1 , wherein n is 5.

4 . The liquid medium of claim 3 , wherein R 3 is hydrogen.

5 . The liquid medium of claim 4 , wherein the counterion is selected from the group consisting of chloride, bromide, and iodide.

6 . The liquid medium of claim 5 , wherein the counterion is chloride.

7 . The liquid medium of claim 3 , wherein R 3 is methyl.

8 . The liquid medium of claim 7 , wherein the counterion is selected from the group consisting of chloride, bromide, and iodide.

9 . The liquid medium of claim 8 , wherein the counterion is iodide.

10 . The liquid medium of claim 3 , wherein R 3 is an oxygen atom.

11 . The liquid medium of claim 3 , wherein R 3 is C 1 -C 6 alkyl, substituted with sulfonate.

12 . The liquid medium of claim 3 , wherein the compound is 6-(dimethylamino)-N-(3-(1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl) oxy) trisiloxan-3-yl) propyl) hexanamide, having the following formula:

13 . The liquid medium of claim 6 , wherein the compound is 6-(dimethylamino)-N-(3-(1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl) oxy) trisiloxan-3-yl) propyl) hexaminium chloride, having the following formula:

14 . The liquid medium of claim 9 , wherein the compound is 3 6-((3-(1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl) oxy) trisiloxan-3-yl) propyl) amino)-N,N,N-trimethyl-6-oxohexan-1-aminium iodide, having the following formula:

15 . The liquid medium of claim 10 , wherein the compound is 6-((3-(1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl) oxy) trisiloxan-3-yl) propyl) amino)-N,N-dimethyl-6-oxohexan-1-amine oxide, having the following formula:

16 . The liquid medium of claim 11 , wherein the compound is 4-((6-((3-(1,1,1,5,5,5-hexamethyl-3-((trimethylsilyl) oxy) trisiloxan-3-yl) propyl) amino)-6-oxohexyl) dimethylammonio) butane-1-sulfonate, having the following formula:

17 . The liquid medium of claim 11 , wherein the compound is 5-((6-((3-(1, 1,1,5,5,5-hexamethyl-3-((trimethylsilyl) oxy) trisiloxan-3-yl) propyl) amino)-6-oxohexyl) dimethylammonio) pentane-1-sulfonate, having the following formula:
