| Abstract | ||||
| Seven undiluted essential oils (Tea tree oil, Eucalyptus oil, Lavender oil, Chamomile oil, Camphor oil, Peppermint oil and Orange oil) were investigated for their antimicrobial activity against bacteria previously isolated from face moisturizing cream samples of different brands in Egypt. All of the tested essential oils exhibited antimicrobial activity against Gram positive bacteria (Bacillus licheniformis, Bacillus subtilis, Bacillus cereus, Lactobacillus fermenti, Listeria sp, Micrococcus luteus, Micrococcus sp, Staphylococcus epidermidis, Staphylococcus aureus) and against Gram negative bacteria (Klebsiella oxytoca and Pseudomonas putida ). Filter paper disc and agar diffusion well methods were used for screening the susceptibility. The results obtained indicated significance differentiation between the two methods. Essential oils of Tea tree oil, Eucalyptus oil, Lavender oil and Peppermint oil were more effective than that of Orange. On the other hand, Chamomile and Camphor oils were partially effective against tested bacteria. Minimum inhibitory concentrations (MIC) of the strongest oils were ranged from 0.08% of eucalyptus oil against bacillus subtilis to 2% of orange oil against listeria sp. Minimum bactericidal concentrations (MBC) were also measured. | ||||
