Abstract: 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.

Abstract: The invention relates to a method for the production of a solid fragrance concentrate, by absorption of a liquid fragrance or fragrance mixture in a solid or solid mixture, using one or several surfactants and/or co-surfactants, solid at normal temperatures as solid or solid mixture, whereby the liquid fragrance or fragrance mixture is dissolved in the above at a temperature above the solidification temperature of the solid or solid mixture and the solution subsequently solidified by cooling. The solid or solid mixture comprises fatty alcohol(s) or a mixture of fatty alcohol(s) and fatty acid(s) and/or fatty alcohol ethoxylate and/or polyethylene glycol.
