A process for producing micronized dispersed micro-particles and to micro-particles produced by this process. In the process a combination of a dispersion liquid, an active ingredient and a wax is passed at a temperature at which the wax is molten into a high energy micro-particle producing machine operating at a temperature at which the active ingredient and wax are kept molten and producing a composition comprising a plurality of micro-particles dispersed in said dispersion liquid by cooling said combination to a temperature below the solidification temperature of each of said micro-particles before each said micro-particle leaves said micro-particle producing assembly.
