Abstract

The invention relates to a method for production of a suspension of solid particles of at least one product. The method is characterised in comprising the following steps: dissolution of the product in a compressed fluid, expansion of said solution by decompression means with simultaneous atomisation of a liquid in which the product is insoluble or poorly soluble and collection of the particles thus formed in suspension in the liquid.
