Abstract

This research has three objectives: 1) To examine the antioxidant effects of pomelo peel extract 2) To develop a facial mask product containing ingredients from pomelo peel extract and 3) To test the satisfaction of users of facial mask products from pomelo peel extract by taking 250 grams of pomelo peel, drying and grinding it into powder, extracted with 95% ethanol solvent at a ratio of 1 gram per 3 milliliters for a period of 24 hours then evaporate ethanol by using Rotary Evaporator at 50 C. The pomelo peel extracts were tested for antioxidant activity by using DPPH radical scavenging assay. Developed 4 formulas of facial mask products with antioxidant effects from pomelo peel extracts with concentrations of 0, 1, 3 and 5 respectively, evaluating physical properties by observing color, scent, stickiness, texture and pH. Using Heating-Cooling cycle method for stability test of the product, closed patch test method for skin test and evaluated satisfaction of 20 volunteers who used the product. Statistics used in data analysis include percentage, mean, standard deviation and One-way ANOVA. The research results found that the antioxidant activity of pomelo peel extract using the DPPH radical scavenging assay found that pomelo peel extract had an IC50 value of 2.1752 ± 0.834 g/ml. The vitamin E standard had an average IC50 of 277.7408 ± 58.8407 g /ml. All four face mask cream formulas have a pH value of 6. The texture of the products in formulas 1 and 2 is thick cream, while formulas 3 and 4 have a thin cream texture. The color of formula 1 is white, formula 2 is cream, formula 3 is yellow, and formula 4 is brown. The scent of formula 1 is odorless, while formulas 2 and 3 have a slightly pungent smell, and formula 4 has a moderately pungent smell. The skin absorption times for formulas 1, 2, 3, and 4 are 30 ± 4, 18 ± 1, 16 ± 0, and 13 ± 1, respectively. There were no redness and signs of irritation, swelling, or redness in the volunteers after irritation testing. The mean overall satisfaction with the product Face Mask Cream from Pomelo Peel Extract. The highest was Formula 2 (4.16 ± 0.58), followed by Formula 1 (3.86 ± 0.72), Formula 3 (3.56 ± 0.62). and Formula 4 (3.06 ± 0.49), respectively. Comparing the level of satisfaction with the 4 formulas of pomelo peel extract facial mask cream showed statistically significantly different at the 0.05 level.
