Test of sunscreen activity of pineapple weevil ethanol extract (ananas comosus (L.) merr.) in gel and lotion preparations

Abstract

Pineapple weevil waste is a residual part of the pineapple flesh which is usually thrown away and not used because of its hard inside. Sunscreen is a skin care product that serves to protect the skin from the dangers of the sun's rays. The purpose of this study was to identify the activity of gel and lotion sunscreens from pineapple weevil extract. This research method is pineapple weevil extract formulated into gel and lotion preparations, evaluation of the physical quality of preparations including organolepticality, homogeneity, pH, viscosity, dispersion, and adhesion as well as determination of spf values of gel and lotion preparations using UV spectrophotometry. The results of the study were obtained organoleptis gel preparations have a yellow color, gel shape, homogeneous, pH 7-7.6, viscosity 4340-5650 Cpoises, spreading power 6.6-7cm, adhesion -7-4.46 seconds. While the lotion preparation has a yellow color, lotion shape, homogeneous, pH 7.3, viscosity 1530 Cpoises, spreading power 7cm, adhesion 4.06 seconds. The SPF value obtained by the pineapple weevil sunscreen gel, which is 30.15, included in the ultra protection. Meanwhile, pineapple weevil sunscreen lotion, which is 42.23, included in the ultra protection. Overall, the pineapple weevil gel and lotion have good physical quality and have the efficacy of being a sunscreen.
