One-step dispersion method for the microencapsulation of water soluble substances |
| 摘要 |
The present invention relates to microcapsules and methods of preparing microparticles with an extremely high encapsulation rate. In a O/W system, by skipping the step of a stable primary emulsion comprising organic solvent droplets, and by carefully setting the physico chemical parameters, microparticles produced by the method of the present invention show surprisingly good agent retention qualities.
