Formulation of Anti Acne Loose Powder of Bawang Dayak (Eleutherine bulbosa (Mill.) Urb.) Ethanol Extract

Abstract

Bawang dayak (Eleutherine bulbosa (Mill.) Urb is one of the notable Iridaceae family, originating from Central Borneo, Indonesia. Previous studies have reported that bawang dayak ethanol extract and its cream preparation have antibacterial properties that can inhibit the growth of acne-causing bacteria and cause no significant skin adverse reaction. This study aimed to make a loose powder preparation from bawang dayak ethanol extract and determine its physical evaluation and antibacterial activity. Loose powder formulation was made with various concentrations of bawang dayak ethanol extract, F0 (0%), F1 (5%), F2 (10%), and F3 (15%). Loose powder evaluates for organoleptic, homogeneity, and antibacterial activity by the disc diffusion method. The results show that bawang dayak ethanol extract can produce a loose powder formulation. The color of the formula is rather yellow (F0), brown-ash (F1), and light brown (F2 and F3), which has a typical mint odor, smooth texture, and homogeneous. All formulations were able to inhibit the growth of P. acnes, S. epidermidis, and S aureus. This present study showed the potential of Formula 3 (F3) as an anti-acne loose powder due to its organoleptic properties, homogeneity, and antibacterial activity, which has the largest diameter of inhibition zone of 17.6 ± 3.1 mm.
