Abstract

Many Indonesian plants have the potential to have anti-acne activity, one of which is the red betel plant. Red betel leaf (Piper crocatum) contains flavonoids, alkaloids, tannins, and essential oils which are thought to be used as antimicrobials. The purpose of this study was to test the quality characteristics and test the antibacterial activity of red betel leaf essential oil against Propionibacterium acne bacteria. This research was an experimental study by identifying the physical quality and testing the antibacterial activity of the essential oil. human senses with the results of the smell or aroma obtained, namely the strong or stinging characteristic odor of red betel. The color of the essential oil obtained was yellow with a little brownish, bitter taste, the pH obtained from the essential oil was 4.65, the specific gravity of red betel leaf essential oil was 0.739, the ethanol soluble test obtained from the essential oil completely dissolved and white clear in a quantity of alcoholic solution. Antibacterial activity test results with red betel leaf essential oil concentrations of 5%, 10%, and 20%, could inhibit antibacterial of 7.16 mm, 10.3 mm, and 11.6 mm.

Abstract

ABSTRACT Free radicals are unstable molecules that can damage cell membranes, DNA, and proteins, thereby triggering premature aging. Preventive efforts can be carried out through skin care using cosmetic products containing natural antioxidants, which are considered safer and capable of providing long-term protection. One cosmetic product that functions as a moisturizer is face toner. Fragrant pandan leaves (Pandanus amaryllifolius Roxb.) are known to contain antioxidant compounds, making them potential active ingredients in face toner formulations. This study aimed to formulate a face toner containing fragrant pandan leaf extract in three concentration variations, namely 1%, 2%, and 3%. Antioxidant activity was evaluated using the DPPH method to determine IC₅₀ values. Physical quality evaluations were also conducted, including organoleptic tests, homogeneity, pH, and viscosity. The results showed that formula 0 had an IC₅₀ value of 261.11 ppm (very weak), formula 1 had an IC₅₀ value of 51.95 ppm (strong), formula 2 had an IC₅₀ value of 40.32 ppm (very strong), and formula 3 had an IC₅₀ value of 32.91 ppm (very strong). In addition, all formulations (0%, 1%, 2%, and 3%) met the physical quality requirements for cosmetic preparations. Keywords: Antioxidant, Fragrant Pandan Leaves, Extract, Face toner
