A NANOPARTICLE PROCESS OF PANTHENOL USING MOLECULAR ASSOCIATION NEAR CRITICAL REGIONS

摘要

Method for producing the nanoparticle of panthenol is arranged to increase the skin contribution ratios of panthenol by cumulative effective cross-section by supercritical fluid process, so that the nanoparticle of panthenol can be used for treating acne without uncomfortable side effect. Method for producing the nanoparticle of panthenol includes the following steps:: solubilising 0. of the panthenol in organic solvent (such as ethyl alcohol)0001-0.50 weight %, prepare pantoyl alcoholic solution; The pantoyl alcoholic solution for spraying especially critical liquid forms panthenol nanoparticle; Organic solvent is removed from panthenol nanoparticle by introducing other especially critical liquid to panthenol nanoparticle; Collect the panthenol nanoparticle of forming.
