Candle nut (Aleuritas molucana) is a plant that can produce oil to stimulate hair growth because it contains oleic acid which is an antioxidant. One core of candle nut seeds can contain as much as 50-60% oil, which can be made into hair care cosmetics through the preparation of hair tonic nanoemulsion. This study aimed to determine the effect of different concentrations of candle nut oil (5%, 6%, and 7%) on the characteristics and stability of a candle nut oil nanoemulsion hair tonic preparation. Candle nut oil was formulated into hair tonic nanoemulsion preparations and then tested for characteristics and stability for cycling test preparations. It was found that there were differences in the characteristics and stability values of formulas I, II, and III. The variations in the concentration of the active ingredient of candle nut oil (5%, 6%, 7%) affected the characteristics of the hair tonic by affecting the droplet size, polydispersity index, zeta potential, pH and viscosity of the preparation. The stability test using the cycling showed that the stability of the hair tonic was affected through changes in the pH value and viscosity of the preparation. Keywords: candle nut oil, characteristics and stability, hair tonic, nanoemulsion
