Abstract

A chronic exposure to Ultraviolet (UV) from sunlight can cause skin damage or skin disease. Applying cosmetic products such as skin lotions containing antioxidant can protect the skin from UV. Coffee pulp is a major coffee waste in the coffee industry and has a natural antioxidants compound. The aim of this study was to apply the coffee pulp extract powder into the skin lotion formulation, also study the phenolic content, antioxidant activity inside the coffee pulp skin lotion and its stability. First, the Coffee pulp was extracted at sample to solvent ratio 1:10 (w/v) using ethanol/water mixtures at various extraction temperature and time to obtained the optimum extraction condition. The coffee pulp extract solution extracted at its optimum condition (50°,120 minutes) was pulverized become coffee pulp extract powder. The yield of the pulverization was 21.7146 g powder/ 100 g CP. The coffee pulp extract powder was added into the skin lotion formulation with four different concentration (0.125%, 0.25%, 0.5% and 1%). All coffee pulp skin lotion was chosen as the suitable concentration since it shows good physical stability, passed the stability testing and have a great amount of antioxidant activity (IC50 Range: 5,805 – 55,776 ppm) compared to commercial lotions (IC50 Range: 505,018 – 557,218 ppm).
