摘要:
Preparation and properties of solid lipid nanoparticles carried octyl methoxycinnamate(OMC)were studiedThe influence of octyl methoxycinnamate(OMC)and pH value on the distribution, size, Zeta potential of solid lipid nanoparticle were studiedMeanwhile the configuration, particle size, composition and sunscreen properties were characterizedThe result showed that the Zeta potential of solid lipid nanoparticle was about 40 mV with optimizing composition and middle or weak basic pH condition The average particle size of solid lipid nanoparticle was about 150 nm and the particle distribution was homogeneousParticle configuration was spherical with or without OMC and little flocculationCarried OMC increased the particle sizeOMC with lipid material, emulsifier formed the solid lipid nanoparticle together but not carried in the coreThe solid lipid nanoparticle with OMC have good ultraviolet adsorption and the synergy function was between the solid lipid nanoparticles and sunscreen.
