Synthesis of Nanogold and Stability Test of This Colloidal as Essential Material in Drug, Supplement and Cosmetics

Nanogold has been used in cosmetics material as anti-aging and sunscreen. Nanogoldwasan activity to reduction free radical. Nanogold reduced wrinkles and aging, support tissue connecting, increase cell proliferation and increase collagen biosynthesis. Nanogold used essential drug material at degenerate deses for example cancer, diabetes mellitus, tumor and ect. This research purposedto synthesis of nanogoldand analysis of stability nanogold colloidal. Nanogold synthesis used glycerin as matrix. The value of stability thenanogold colloidal to be analysis at 6 weeks with 5, 10, 15, 20, 25 and 30 ppm of concentration. The results of the research, the stability ofnanogold colloidal occur after 5 weeks at 5, 10, 15, 20 and 25 ppm. Nanogold colloidal at 30 ppm of concentration was not stabile,becausethere aggregation. Conclude that nanogold colloidal with 5, 10, 15, 20 and 25 ppm of concentration are recommended as support material in drug, supplement, and cosmetics.
