NANOEMULSION COMPOSITION COMPRISING VITAMIN-C DERIVATIVE AND METHOD FOR PREPARING THEREOF |
摘要 |
A liposome nanoemulsion cosmetic composition comprising a vitamin-C derivative is provided to maintain the content by stably encapsulating a vitamin C derivative to liposome in the external environment and to improve percutaneous absorption rate and whitening effect. A method for manufacturing a liposome nanoemulsion cosmetic composition comprising a vitamin-C derivative comprises the steps of: (a) manufacturing liposome containing a vitamin-C derivative; (b) manufacturing an emulsion mixture by dissolving emulsion components of 1-30 weight% at 70-75°C; (c) manufacturing the aqueous mixture by dissolving aqueous components including the liposome containing a vitamin-C derivative at 80°C; (d) manufacturing the first emulsion composition by injecting the emulsion mixture in the aqueous mixture while maintaining the condition to 75-80°C, and emulsifying them; and (e) secondly emulsifying the first emulsion composition by injecting it in a microfluidizer while stirring them under 500-2000bar three thimes.
