THE EFFECTIVENESS OF SPF (SUN PROTECTOR FACTOR) VALUE IN EMULGEL PREPARATIONS BASED ON BALINESE MANGOSTEEN PEEL (Garcinia mangostana L.)

Abstract

Indonesia is a country located on the equator, so it has a fairly high exposure to solar intensity. Exposure to UV rays can cause skin damage, premature aging, skin pigmentation, and wrinkles due to prolonged exposure. The use of sunscreen is one of the solutions to reduce exposure to UV rays. Balinese mangosteen peel (Garcinia mangostana L.) has the potential to be developed as a sunscreen. The purpose of this study was to examine the effectiveness of SPF (Sun Protector Factor) value in emulgel preparations based on the peel of Balinese mangosteen fruit (Garcinia mangostana L.) The research method was designed using a true experimental design method with a posttest-only control design. Data analysis uses a descriptive statistical approach. The results of the phytochemical test showed that the mangosteen peel was positive for containing secondary metabolite compounds. The physical stability test showed a pH of 7 or normal, homogeneous, and a dispersion of 5 - 7 met SNI requirements. The SPF value performed in vitro using UV-Vis spectrophotometry showed a variation of 200 ppm, 400 ppm, and 800 ppm; the SPF value was 68.7, 70.23, and 70.72. These SPF values indicate the potential of the mangosteen peel as a sunscreen, with the 200 ppm formulation showing the highest SPF value. The organoleptic results conducted by 35 respondents show that the color category is very fond, with a percentage of 51.40%. The texture category has a percentage of 51.40%. The scent category really likes 45.70%. So it can be concluded that only using a variation of the 200 ppm formulation is able to provide ultra SPF potential.
