In Korea-U.S.A. FTA Negotiation, U.S.A. request to eliminate barriers of tariffs and non-tariff in trade of cosmetics. Korea applies tariffs of 8% on most cosmetics and personal care products. There are some non-tariffs barriers in cosmetics trade between Korea and U.S.A., for example, transparency on restriction and regulatory, cosmeceuticals, import clearance review, quality control testing, ingredient labelling. Tariffs of 8% on most cosmetics should be eliminated, a proviso of complementary measures on sanitation of Korean people about imported cosmetics. This is a meaning of reformation of prior management(tariffs) by strong ex post management in cosmetics trade. It is important that Korea should construct system of ex post management, for instance, construction of data base on manufacturer, importer, bland name of cosmetics and all ingredients of cosmetics. This is concerned with labelling of cosmetics and cosmeceutical and publication of Korean edition of INCI(International Nomenclature of Cosmetic Ingredient).

In this study, we evaluate anti-oxidation, whitening and anti-inflammatory efficacies of Euphorbia jolkini extract for application as a cosmeceutical ingredient. We separated 5 fractions from Euphorbia jolkini extract (70 % MeOH) by MPLC. First and 5th fractions showed a supressive effect on Mn-SOD synthesis in the normal human fibroblasts. They inhibited melanogensis in the B16-F10 melanma cells. Furthermore, 1st and 5th fractions reduced the amounts of $IL-1{\alpha}$, IL-6, COX-II and total NO secreted from the normal human fibroblasts. These results suggest that Euphorbia jolkini extract may be used as an active ingredient in cosmetics.

Objectives : The purpose of this research was physiological activities, cytotoxicity, and antibacterial activities of the Cheongyeolsodokum and its constituent herbs. Methods : Physiological activities, cytotoxicity, and antibacterial activities were examined through the Cheongyeolsodokum and its constituent herbs. Results : In the physiological activities, the electron donating ability(EDA) of the water and ethanol extracts from the Cheongyeolsodokum were over 60% and 80% at 100 ppm, respectively. The EDA of the water and ethanol extract from the Cheongyeolsodokum ingredients were gradually increased as well. Water and ethanol extracts from the Cheongyeolsodokum and its constituent herbs inhibited xanthine oxidase activity, they showed superoxide dismutase(SOD)-like activity. The Cheongyeolsodokum and its constituent herbs inhibited cancer cell growth in a dose-dependant manner. Also, the clear zones against Staphylococcus aureus and S. epidermidis were clear shown at 2.5 and 5 mg/disc. Its constituent herbs showed the clear zone against various bacteria such as Candida albicans, S. aureus, S. epidermidis, and S. mutans were shown at 0.5 and 1mg/disc. Conclusions : We observed physiological activities, cytotoxicity, and antibacterial activities of the Cheongyeolsodokum and its constituent herbs. The results also indicated that water extract and ethanol extract of Cheongyeolsodokum and its constituent herbs can be used as a natural ingredient in food or cosmetic industry.

To develop cosmetics using Jindalae flowers (Rhododendron mucronulatum), the surface tensions of extracts were measured and the properties and stability of cream with extracts were investigated. The surface tension of 0.1% ethanol extract was 30.42 mN/m and that of distilled water was 72.2 mN/m. The surface tension of cream with 0.1% ethanol extract was similar to that of sample cream and the measured pH were weakly alkalic. The surface tension of 1% ethanol extract was the lowest value of 24.98 mN/m, the measured pH of cream with 1% ethanol extract was weakly acidic and the particle size of cream was stable. According to an oscillatory test, linear viscoelastic region was extended by adding of 1% water extract and 1% ethanol extract to cream, indicating that the cream had greater enhanced resistance for preserving inner structure as compared to outside stress.　Besides, as a result of the diminished loss angle of ethanol extract cream, the elasticity of cream was increased more than that of sample cream and cream with 0.1% ethanol extract. In contrast, in the case of the increased loss angle of water extract cream, the viscosity of cream was increased. In conclusion, Rhododendron mucronulatum can be deliberated as a cosmetic material because 0.1% water and ethanol extracts showed efficacious physiological activities and cream with 1% extracts could extend linear viscoelastic region.
