METHOD OF COATING FINE PARTICLE WITH LIPID FILM

A simple method of coating fine particles with a lipid film safely and efficiently. The method is characterized in that an aqueous polar-organic-solvent solution which contains fine particles dispersed therein and a lipid dissolved therein is modified so as to reduce the proportion of the polar orga...

Summary:A simple method of coating fine particles with a lipid film safely and efficiently. The method is characterized in that an aqueous polar-organic-solvent solution which contains fine particles dispersed therein and a lipid dissolved therein is modified so as to reduce the proportion of the polar organic solvent to thereby coat each fine particle with a lipid film. L'invention concerne un procédé simple de revêtement de fines particules avec un film de lipides, réalisée de manière sûre et efficace. Ledit procédé est caractérisé en ce qu'une solution aqueuse de solvant organique polaire, renfermant de fines particules dispersées et un lipide dissous, est modifiée de manière à réduire la proportion du solvant organique polaire, afin de recouvrir chaque fine particule d'un film de lipides.
