Formulation And Physical Quality Test And Antioxidant Activity Test Of Body Butter Preparation Of Ethanol Extract Of Rambutan Fruit Peel (Nephelium Lappaceum L.)

Abstract

This research was conducted in the utilisation of natural ingredients in the preparation of body butter made from rambutan fruit peel (Nephelium lappaceum L.) which contains flavonoid compounds as antioxidants. This study aims to determine the physical quality and antioxidant activity of body butter preparation of ethanol extract of rambutan fruit peel (Nephelium lappaceum L.) conducted at the Pharmacy Laboratory of Muhammadiyah University of Palopo in September-October 2023. It is a type of experimental research with procedures for processing samples, making body butter preparations, testing the physical quality of preparations, and testing antioxidants. The body butter formulation was carried out with a concentration of rambutan fruit peel extract 0% (F0), 6.4% (F1), 16.4% (F2) and 26.4% (F3). The results showed that the preparation met the physical quality, namely texture/cream shape, light brown F1, slightly dark brown F2 and dark brown F3, vanilla odour, each preparation met the homogeneity requirements, pH 7, viscosity test ranged from 3906-4292, stickiness 7-8 seconds, spreadability test 5.7-6.0 cm. The results of the liking test of 4 F1 formulas were the most preferred, the humidity test was 41.15%-55%, and the irritation test of all formulas was not irritating. Antioxidant test results IC50 value of F1 166.68 µg/mL, F2 73.61 µg/mL, F3 1.89 µg/mL.
