Claim Text:
1. A composition for application to skin, hair or external mucosa comprising: an aqueous-solvent fluid and submicron particles of hydrophobic agent(s) of average particle size from 100 nm to 999 nm dispersed and suspended in the aqueous-solvent fluid, wherein the submicron particles are 90% wt. or more non-polar, wherein 85% or more of the submicron particles have a size within 300 nm of the average particle size; wherein the aqueous-solvent fluid comprises wherein 70% wt. or more of the one or more water miscible solvents, and 30% wt. or more of the aqueous-solvent fluid, is one or more mono- or di-hydroxy compounds selected from the group consisting of C wherein the hydrophobic agent(s) comprise 0.01 to 70% wt. of the skin, hair or mucosal composition; wherein the composition is substantially surfactant-free, wherein the amount of surfactant, if present, is not sufficient to materially lower the surface tension of the aqueous-solvent fluid; and wherein the dispersed submicron particles are stable.
