Lemongrass essential oil in liquid bath soap preparations as an antibacterial agent can increase the effectiveness of soap in its function as a skin cleanser. Objective: This study aims to make a citronella dishwashing liquid soap formulation and test its quality, namely homogeneity, organoleptic, pH, foam stability, viscosity. and anti-bacterial activity. Methodology: This type of research is an experimental study using a completely randomized design (CRD) consisting of one factor and three repetitions. The sample in this study was Lemongrass essential oil resulting from steam distillation in the Staphylococcus Aureus anti-bacterial liquid wash formulation. The measurement parameters were homogeneity, PH, viscosity, organoleptic, foam stability and bacterial inhibition. Data analysis was carried out descriptively, presented in the form of tables and graphs. Results: The results of the formulation research were F1: 1%, F2: 1.5%, F3: 2%. The organoleptic test results obtained soap with a distinctive lemongrass smell, clear purple in color, in the form of a viscous liquid. Test the homogeneity of all homogeneous formulations. The pH test results are 8.67-9. The height test results and foam stability ranged from 85.38%, - 88.70 %, the viscosity test results ranged from 1,574–51,274. Bacterial inhibition range: 0.03 – 8.70 mm. Conclusion: The lemongrass liquid soap formula that has been made concludes that the formulation meets SNI standards
