Abstract
The invention provides process for making contra-soluble nano-dispersions of at most sparingly-soluble materials in a soluble carrier material comprising the steps of: (i) providing a single phase mixture of: a) a solvent or a mixture of miscible solvents, b) at least one carrier material soluble in solvent (a), said carrier material being also contra-soluble to payload material (c) and solid at ambient temperature, c) at least one a payload material which is soluble in solvent (a), and, (ii) drying the mixture to remove solvent (a) and thereby obtain the carrier material (b) in solid form with payload (c) dispersed therein as nanoparticles.
