Abstract

Antioxidant compounds reduced aging of the skin. Red dragon fruit peels contained antioxidant compounds. This research purposed to determine the red dragon fruit peels can be made preparation peel-off mask gel with variation carbopol 940 and propylene glikol as the influence of variations in the physical basic of the quality of preparation and antioxidant activity. Red dragon fruit peels extraxtion by maseration method using 70% ethanol. Peel-off mask gel made with variation concentration of carbopol 940 and propylene glycol which is 0,5%:5%; 0,5%:7,5%; 0,5%:10%, 1%:5%; 1%:7,5%; and 1%:10%. Antioxidant test used DPPH (1,1-dyphenil-2-picrylhydrazyl) method. The evaluation used for observing the physical properties which include organoleptic, time to dry, viscosity, spreading, and pH, with antioxidant activity of each formula. The results showed that the red dragon fruit peels can be made into a preparation peel-off mask gel. Concentration high of carbopol 940 and low of propylene glycol affected quality of the preparation is high viscosity, low dispersive power, acid of pH, dried up a long time, and low antioxidants activity. Keywords: red dragon fruit peels, carbopol 940, propylene glycol, peel-off mask gel
