<p>A solvent system for use in a microemulsion or protomicroemulsion where the solvents are selected to have a Hansen parameter ofδd to be from 15 to about 18; ofδp to be from 0 to about 8 and ofδH to be from 0 to about 12; such that the resulting Hansen parameter of the solvents comprises has aδd of from 15 to about 18; aδp from about 2 to about 8 and aδH of from about 5 to about 12.</p> |
