Abstract

Introduction

Soaps are vital for preserving our health and personal hygiene since they not only eliminate germs but also rid the body of pollutants.

Method

The current study aims to determine the physicochemical and antibacterial properties of Eucalyptus camaldulensis leaves using the agar disc diffusion technique and assess the effectiveness of different branded liquid soaps (25 mg/ml, 50 mg/ml, 75 mg/ml, and 100 mg/ml) with the Eucalyptus leaf extract against skin-infecting human pathogenic bacteria.

Results

The combined antimicrobial susceptibility of E. camaldulensis and five liquid soaps showed an inhibition zone of 17.67±0.58, 13.33±0.58, 12.67±0.58, and 15.67±0.58 against Staphylococcus aureus, Streptococcus pyogenes, Pseudomonas aeruginosa, and Escherichia coli. The antibacterial properties of Av soap by itself did not work against S. pyogenes. Nevertheless, the extract and DI together showed a detrimental effect against S. aureus and P. aeruginosa, with no halo forming.

Discussion

The absence of inhibition zones for the extract combined with DI against S. aureus and P. aeruginosa may indicate antagonistic interactions or reduced efficacy in that formulation. Overall, the data highlight the potential of E. camaldulensis to improve the antimicrobial properties of commercial soaps, though the effectiveness varies with microbial strain and formulation.

Conclusion

Antimicrobial activity was observed to increase with higher concentrations of the soap-extract combinations. Although liquid soap (seve) was effective against bacterial isolates, a combination of eucalyptus and aqua vera was shown to be more effective.
