| titleOfInvention | A kind of styrene cross-linked polymer particle for loading fat-soluble sun-screening agent and preparation method thereof |
| abstract | The present invention discloses a kind of styrene cross-linked polymer particle and preparation method for loading fat-soluble sun-screening agent, the styrene cross-linked polymer particle of the fat-soluble sun-screening agent of load is core shell structure, core is fat-soluble sun-screening agent, shell is styrene cross-linked polymer, its particle diameter is between 57.8 4747nm at 25 DEG C, and embedding rate is between 38.05 62.20%.Its preparation method is at room temperature to dissolve surfactant in deionized water, and stirring and dissolving is used as aqueous phase；Fat-soluble sun-screening agent and styrene, divinylbenzene are well mixed and are used as oil phase, gained oil phase homogeneous mixed with water emulsify obtaining emulsion, then initiator is added, it is stirred at 50 DEG C of bath temperature, react and stop reaction after 4 6h, demulsification filtering, produces the styrene cross-linked polymer particle for loading fat-soluble sun-screening agent.Avoid fat-soluble sun-screening agent from being contacted with the direct of skin, reduce absorption and excitant of the skin to fat-soluble sun-screening agent. |
