Butterfly pea flower (Clitoria ternatea L) is a plant that contains flavonoid compounds, especially anthocyanins, which have strong antibacterial properties. From these plants, you can make a face toner from natural ingredients. This study aims to determine the results of butterfly pea flower infusion that can be used as an anti-bacterial face toner preparation and which formulation is the best in terms of the physical properties of the preparation. This study used butterfly pea flower infusion with infusion concentrations of 10%, 15% and 20%. The research method used is an experimental method by making 4 formulations of face toner preparations, then conducting physical tests on the preparations including organoleptic tests, homogeneity tests, pH tests, viscosity tests, drying time tests, leak tests, specific gravity tests and drop tests. Then an antibacterial test was carried out against propionibacterium acnes using the disc method. The results of the study showed that the preparation of face toner with butterfly pea flower infusion was effective in inhibiting bacterial growth. The highest infusion concentration, namely 20%, provided the greatest inhibitory power of 23.5 mm, this shows that the higher the concentration of butterfly pea flower infusion used, the greater the inhibitory power against bacterial growth. The formulated preparations also meet the testing standards. Therefore, the preparation of face toner with butterfly pea flower infusion is an ideal choice for natural skin care, especially for those who have oily or acne-prone skin problems.
