Abstract: Trans-cinnamaldehyde is the major chemical compound of cinnamon oil which is potential as an antibacterial agent.Due to this activity, Cinnamon oil can be formulated into a lotion for practical use.This study aimed to determine the antibacterial activity of cinnamon oil and cinnamon oil lotion against Staphylococcus epidermidis, which causes unacceptable foot odor.This study was a pure experimental study.Stages of this study were starting from the obsevation of antibacterial activity of Cinnamon oil against Staphylococcus epidermidis silicone-lube which was done by using diffusion method to determine the concentrations used in the formulation.
Cinnamon oil was then formulated into lotions with variation of concentrations of 12; 18; and 24% (w/w) respectively.Furthermore, the quality of lotion based on its physical properties such as viscosity and spread-ability, and the antibacterial activity of lotion were determined.The inhibition zones then were statistically analyzed by using the Kruskal-Wallis test with assistance of R 2.14.1software.
The result showed that cinnamon oil lotion had good Pennants physical properties at a concentration of 12% (w/w).Cinnamon oil itself and the formulations had significant activity against Staphylococcus epidermidis.Moreover, cinnamon oil and its formulation showed similar antibacterial activity against Staphylococcus epidermidis.Keywords : antibacterial activity, cinnamon oil, lotion, Staphylococcus epidermidis.
