The preparation of gel-trapped water phase was studied using hydrophilic characteristics of polymer in W/O emulsion. In most cases, polymers were used to stabilizer the outer water phase in O/W emulsion. However, in our novel method, we applied polymer in inner phase to form a gel-type water phase in water-in-oil emulsion. This geltrapped water in oil emulsion resulted stable formulation at high temperature. So, this method gives an opportunity to prepare a cosmetic product of a unique appearance. Detailed characterization of the emulsion was performed to elucidate the properties of the emulsion. |
