Abstract (en)

[origin: FR2775441A1] The invention concerns a matrix for preparing microparticles or nanoparticles, method for making said particles and resulting particles, more particularly a matrix for forming microparticles or nanoparticles by hot dispersion in a non-miscible gas or liquid medium, characterised in that it consists of at least a solid hydrophobic element at room temperature and of at least a liquid element, hydrophobic and/or lipophilic, hot mixed by solubilizing the solid element(s) in the liquid element(s), said matrix having a melting point ranging between 25 DEG C and 85 DEG C.
