Abstract
The moisturizing effect and stability of a cream containing 0.25 % Inula britannica flower ethyl acetate fraction were investigated. The pH, viscosity, and absorbance were measured under 4 different temperature conditions(4, 20, 37, and $45^{\circ}C$) and under the sun light at 2 week intervals for 12 weeks. The variations in pH and viscosity of all experimental creams were similar to those of control cream. The absorbance variations of the extract from experimental cream at 330 nm were in the order: under the sun > 45 > 37 > 25 > $4^{\circ}C$. It shows that ethyl acetate fraction in the cream can be oxidized under the sun. In addition, any change in color or smell was not observed through 12 weeks of the experimental period. These results showed that the cream were stable. Accordingly, it is suggested that further study is needed to provide more information to the manufacturers, who are seeking for the application of the extract to improve the anti-oxidant and antibacterial activities and stability of cosmetic products.
