Abstract

This research study aimed to evaluate the antibacterial activity of Averrhoa bilimbi L. and Psidium guajava extracts individually and in combination for formulating antibacterial liquid soap. Three sets of liquid soap formulations were tested, including 50% bilimbi extract and 50% guava extract, 100% bilimbi extract, and 100% guava extract. The assessment focused on pH values, foam retention capacity, color, and odor of the formulated liquid soaps. All formulations met the required pH level for liquid soap and demonstrated superior foam retention capacity compared to commercially available alternatives. The liquid soap prototypes exhibited an appealing planter green color and a pleasant odor characterized by a fresh and musky fragrance, further enriched by the addition of lavender essential oil. Significantly, the liquid soap containing the combined guava and bilimbi extract displayed remarkable antibacterial properties against both E. coli and S. aureus, surpassing the effectiveness of commercial liquid soaps. While bilimbi extract alone did not exhibit antibacterial activity against the tested bacteria, its combination with guava extract exhibited potential improvements in efficacy against E.coli and S.aureus The statistical analysis using the Kruskal-Wallis test revealed statistically significant differences between the tested concentrations. For E. coli, the p-value was 0.0310, and for S. aureus, the p-value was 0.0200, leading to the rejection of the null hypothesis for both bacteria.
