Patent ID: 6916773

Claim:
A single phase aqueous composition comprising: water, a solvent having a hydrophilic-lipophilic balance value of 5 to 7; and a solvent solubilizing amount of a solubilizing agent having a formula: wherein: R is aryl or heteroaryl; R 1 is a bond, (C 1 - 7 )alkyl, substituted (C 1 -C 7 )alkyl, (C 1 -C 7 )alkoxy, substituted (C 1 -C 7 )alkoxy, (C 2 -C 7 )alkenyl, or substituted (C 2 -C 7 )alkenyl; and Z + is hydrogen, Na, K, or NR′ 4 where R′ is independently selected from group consisting of hydrogen, (C 1 -C 18 )alkyl, substituted (C 1 -C 18 )alkyl, (C 1 -C 18 )alkoxy, substituted (C 1 -C 18 )alkoxy, (C 2 -C 18 )alkenyl, and substituted (C 2 -C 18 )alkenyl; and wherein the composition comprises sufficient solubilizing agent to solubilize the solvent into the water, and the solvent is present at 25-75 wt %, water is present at 25-75 wt %, and solubilizing agent is present at 1-20 wt % of solvent, water and solubilizing agent total weight.
