Abstract
Background: Recent studies have demonstrated that the transmission of SARS-CoV-2 is possible in the form of aerosol and fomite. Thus, hand hygiene is of utmost significance. Hand sanitizer is often used as a practical hand washing method. Purpose: This study aims to study the effectiveness of Moringa leaves extract as an antibacterial ingredient in hand sanitizer gel. Methods: Moringa leaves extract was obtained by maceration in 70% alcohol solution. The hand sanitizer formula consists of carbomer, propylene glycol, glycerin, methylparaben, and triethanolamine. The hand sanitizer gel was prepared using three formulas with different extract concentrations. The quality of the hand sanitizer gel was analyzed, including the gel acidity (pH), organoleptic, the inhibitory ability of bacterial growth against Staphylococcus aureus, and the gel dispersion.Results: This study showed that Formula III has the highest inhibitory area against S. aureus. The gel acidity (pH) was found at around 4 for all the formulas, safe for use on the skin. The organoleptic test showed no irritation to the skin for all three formulas. However, they demonstrated low dispersity. Conclusion: Moringa leaves extract is effective as an antibacterial in hand sanitizer gel.
