Antibacterial Effect of Aroma Oil on Stophylococcus aureus and S. epidermidis

Abstract

This study's primary objective was to confirm the antibacterial effect of aroma oil on <i>Stophylococcus aureus</i> and <i>Stophylococcu epidermidis</i>, the common bacteria of atopic dermatitis. Among the aroma oils, Thyme oil and Cinamon bark oil which have antibiotic effects against <i>S. aureus</i>, were selected through the disk diffusion method. In order to solve problems in use, such as delayed volatility and reduced toxicity of aroma oil, It was made into a gel using biodegradable polymers Curdlan (Curdlan: Cur) and carboxymethyl scleroglucan (CMSG). The experiment involved 4 groups of <i>S. aureus</i> and 4 groups of <i>S. epidermis</i>. As a result of the above experiment, <i>S. aureus</i> growth was completely inhibited in Group I and Group II at 150 μl and 200 μl of thyme oil. In Group III and Group IV, <i>S. aureus</i> growth was entirely restrained when the amount of Cinamon oil added was 200 μl. In Group V and Group VI, the growth of <i>S. epidermidis</i> was completely inhibited when 200 μl of Thyme oil was used. In Group VII and Group VIII, the growth of <i>S. epidermidis</i> was completely inhibited when 200 μl of Cinamon oil was used. The study's findings, in terms of cosmetology, Curdlan is possible to present the possibility of application as a new formulation that can enhance the improvement effect of atopic dermatitis.
