METHOD FOR OBTAINING SOLID PARTICLES FROM AT LEAST A WATER SOLUBLE PRODUCT

摘要

The invention concerns a method for obtaining solid particles from at least a water soluble product, characterised in that it comprises steps which consist in: forming a solution of said product in an aqueous phase, producing an emulsion, or a micro-emulsion, consisting of said aqueous mixture and a polar organic phase, contacting said emulsion, or said micro-emulsion, with a fluid at supercritical pressure, or a liquefied gas, so that the latter extracts the organic phase and the water, thereby precipitating the formed solid particles of the water soluble product, and collecting the resulting formed particles.
