Nanogold as Supporting Activities of Conventional Sunscreen of Octyl-p-Methoxycinnamate to Inhibit Photoaging
Abstract
Research has been conducted in order to determine the potential of nanogold as a material and supporting material of sunscreen. It can contribute to the pharmaceutical design of cosmetics that much more effective, especially as a sunscreen as well as antiaging. Nanogold with various concentrations to be tested, was synthesized without using a matrix so that sunscreen activity really pure due to the activity of nanogold. Test of sunscreen activity and test of supporting capacity of sunscreen material is done by measuring the absorbance of nanogold, OPMC (Octyl-p-Methoxycinnamate) compound, and combinations of OPMC-nanogold using UV-Vis instrument of Simatzu-1700. The results showed that nanogold having sunscreen activity, especially in the high energy UV region at ? 200 nm. Its activities will be higher if the concentration becomes higher. Nanogold also strongly supports the sunscreen activities of OPMC. This is evident from the increase in absorbance value of the combination of nanogold and OPMC.
