Silica-containing composite nanoparticles, and hydrogel moisturizing patch containing same |
| abstract |
The present invention relates to silica/zwitterionic polymer composite nanoparticles, a preparation method therefor, and a hydrogel moisturizing patch containing the same. The silica/zwitterionic polymer composite nanoparticles of the present invention reduces the evaporation velocity of water by displaying a strong binding force to water and exhibits water retention and skin barrier function reinforcement effects, and thus can be used as an artificial moisturizing factor for preparing a hydrogel moisturizing patch or various cosmetic formulations pursuing similar skin effects thereto. |
