Abstract
Rice bran is a side product of rice milling which contains antioxidant compounds such as tocopherols, tocotrienols, and gamma oryzanol. Red rice bran has higher antioxidant activity (IC50 43.2349 ppm) compared with white rice bran. This study aims to formulate and evaluate peel-off gel mask containing red rice bran extract. Dosage formulations of gel peel-off mask made in various types of bases that F1 (using base of polyvinyl alcohol), F2 (base of HPMC) and F3 (base of gelatin). Further preparation gel peel-off gel mask evaluated physical properties (organoleptic, homogeneity, pH, power of spread, test the strength of the film layer and irritation test) and antioxidant activity during the 8 weeks of storage. The results showed that the F1 shows the physical properties of the most well during 8 weeks of storage. While F3 showed the highest antioxidant activity than the other formulas with percent inhibition 88.81%.
