Dragon fruit peels contains many color pigments, one of which is anthocyanin which functions as an antioxidant. This content is able to prevent free radicals that cause premature aging and other diseases. Antioxidants found in dragon fruit peels can be used as active ingredients for cosmetics, one of which is body butter. One of the factors that influence the stability of the body butter preparation is an emulgator. This study aims to determine the effect of the formulation, namely the variation in the concentration of emulgator levels (tween 60: span 60) on the physical stability of body butter. The preparations were made with 3 kinds of 60: span 60 emulsifier concentrations of 1%, 2%, and 3%. The three formulas were tested for physical stability by organoleptic, homogeneity, pH, adhesion, dispersion, and protection. Physical stability tests were carried out at weeks I, II, III, and IV at room temperature. Observation data were analyzed statistically with a confidence level of 95%. The results of the evaluation of body butter preparations showed that variations in the emulgator had no effect on the physical properties of the body butter including organoleptic, homogeneity, pH, and dispersion. But it affects the test of adhesion and protection (p> 0.05). Based on the test results, the results obtained are formula III is more stable in storage for 4 weeks than formulas I and II.Keywords: Hylocereus polyrhizus, emulgators, body butter, physical evaluation

Red dragon fruit peels (Hylocereus polyrhizus) are considered important by the community. While the red dragon fruit peel contains flavonoids, betacyanin, anthocyanin, and vitamin C which have antioxidant activity so that it can ward off free radiation and prevent cell damage. Antioxidants are molecules that can prevent the oxidation of other molecules. Antioxidants can protect the skin from various free radical cell damage. The body butter is a pharmaceutical preparation in the cosmetic field that can be used for skin health care. This study aims to determine the percentage of antioxidant activity and IC50 values in the body butter ethanol extract of red dragon fruit peels. Red dragon fruit peels were extracted first using the maceration method with 96% ethanol solvent. The antioxidant activity test was measured using UV-Vis spectrophotometry. The results showed that the antioxidant activity value of formula I obtained IC50 values (56.17 μg / mL), formula II IC50 values (88.26 μg / mL), and formula III IC50 values (146.05 μg / mL). From the results obtained, the body butter formula which has the greatest activity is the formula I (AAI = 0.7). Antioxidant activity in body butter preparations is included in the group of moderate antioxidants.
