Process for the preparation of micropartu00ecculas soft superfinas and nanopartu00ecculas

摘要

Process for preparing soft micropartu00ecculas superfinas and nanopartu00ecculas ".The invention relates to microparticles and nanoparticles superfinas and a process for preparing soft thereof,With the exception of water or minimisation of water and / or exclusion of plasticizers and / or cargo temperature reduced.In which a material of the matrix is subjected to a homogenization process of high pressure in an anhydrous or poor in water and / or at low temperatures, preferably.Room temperature (20 198 C) and, in particular, below the freezing point of water, which leads to a reduction of soft particles,With the minimization of the deterioration of the chemical stability of the homogenate.
