ABSTRACT:
Compositions of the invention include: (a) a solvent at least partially immiscible in water; and (b) a solubilizing agent having a formula:where R is (C1–C7)alkyl, substituted (C1–C7)alkyl, (C1–C7)alkoxy, substituted (C1–C7)alkoxy, (C2–C7)alkenyl, substituted (C2–C7)alkenyl, aryl, heteroaryl, cycloalkyl or heterocycly; and R′ and R″ is independently selected from hydrogen, (C1–C7)alkyl, substituted (C1–C7)alkyl, (C1–C7)alkoxy, substituted (C1–C7)alkoxy, (C2–C7)alkenyl, or substituted (C2–C7)alkenyl. Further compositions include: (a) a solvent at least partially immiscible in water; and (b) a solubilizing agent having a formula:in-line-formulae description="In-line Formulae" end="lead"?R1—R—OHin-line-formulae description="In-line Formulae" end="tail"?where R is (C1–C7)alkyl, substituted (C1–C7)alkyl, (C1–C7)alkoxy, substituted (C1–C7)alkoxy, (C2–C7)alkenyl, substituted (C2–C7)alkenyl, aryl, heteroaryl, cycloalkyl or heterocycyl and R1is a nitrogen containing heterocycyl or a nitrogen containing hetroaryl. The compositions are useful in providing stable single phase aqueous solutions when combined with water.
