Abstract

Nutmeg leaf essential oil (Myristica Fragrans Houtt.) is one of the natural ingredients which have antioxidant activity and potential as a sunscreen. The research aims to formulate nutmeg leaf essential oil nanoemulsion, characterize, and determine its potency as a sunscreen. Nutmeg leaf essential oil nanoemulsion was formulated with 1; 3; and 5 mL of oil content with two variations of surfactant. The characterization included organoleptic, pH, viscosity, %T, nanoemulsion type, droplet size, thermodynamic and centrifugation stability tests. Evaluation was conducted using UV-Vis spectrophotometer at a wavelength range of 290-400 nm with ethanol as a blank and non-nano-emulsified as a comparison. The result showed that the nutmeg leaf essential oil nanoemulsion had clear and stable appearance, safe for skin, viscosity values of <200 mPas, %T values of near 100%, nanoemulsions type of o/w, and particles size of <200 nm. The evaluation showed that the sunscreen activities of nutmeg leaf oil nanoemulsion was higher than non-nano-emulsified. The highest sunscreen activity was the formula A nanoemulsion which an oil content of 5 mL and had an SPF value of 1.475; %Te value of 50.571%; and %Tp value of 77.218%. The nanoemulsion sunscreen activity of formula A was categorized as a regular suntan

Abstract

ABSTRACT. Hand sanitizer is an essential item during the COVID-19 pandemic, posing potential side effects when containing synthetic ingredients. Therefore, this study aimed to replace hand sanitizer formulation with Citronella essential oil (Cymbopogon nardus L.). Essential oil was fractioned into 3 components, namely F1 (67.07% of limonene), F2 (92.39% of citronellal), and F3 (62.41% of geraniol) while evaluation was conducted on antibacterial properties against E. coli. Antibacterial test was performed using the well diffusion method, showing inhibition zone diameters of 7.40, 10.76, and 8.30 mm for F1 to F3 fractions, respectively. The results showed that F2, selected as the reference for hand sanitizer formulation, had the most potential antibacterial activity and a MIC of 3.125%. Comparative test with commercial alternatives, including hedonic, characteristic, and antibacterial activity test, were conducted to assess the formulated hand sanitizer. F2 was discovered to have an inhibition zone diameter of 29.56 mm as opposed to 9.06 mm of commercial hand sanitizer. Based on hendonic test, hand sanitizer formulated with citronella oil had a distinct smell, which was less preferred than lime fragrance. Keywords: Antibacterial, Escherichia coli, and sanitizer, citronella essential oil.
