This study was a pure experimentalstudy. Stages of this study were starting from the obsevation of antibacterial activity of Cinnamon oil against Staphylococcus epidermidis 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 itsphysical 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 withassistance of R 2.14.1software. The result showed that cinnamon oil lotion had good physical properties at a concentration of 12% (w/w). Cinnamon oil itself and the formulations had significant activity againstStaphylococcus epidermidis. Moreover, cinnamon oil and its formulation showed similar antibacterial activity against Staphylococcus epidermidis
