Determination of Sun Protection Factors (SPF) of Red Dragon Fruit (Hylocereus polyrhizus) extract cream

Red dragon fruit (Hylocereus polyrhizus) has bioactive compounds such as phenols, flavonoids, and betacyanin that can work as active ingredients for sunscreen. The purposes of this study were to determine the SPF value and physical characteristics of red dragon fruit flesh extract cream. The concentrations of red dragon fruit extract used were 0.07% (F1), 0.14% (F2) and 0.28% (F3). SPF value of this cream determine by UV-Vis spectrophotometer. Evaluation of the physical characteristics of the cream includes organoleptic characteristics, homogeneity, pH, physical stability, spread diameter, adhesiveness, and cream type. The results show there was a difference in SPF values in the group given the extract. F1 has the highest SPF value, namely 1.291 ± 0.007. The evaluation of physical characteristics produced a good cream preparation that met the requirements of the physical characteristics of the cream.
