Abstract
A method of making fine dry particles of substances is provided by forming a composition comprising a substance of interest and a supercritical or near critical fluid; rapidly reducing the pressure on said composition, whereby droplets are formed; and passing said droplets through a flow of heated gas. The process does not require any organic solvent.
