Abstract : Manalagi apple peel (Malus Sylvestris Mill) needs to be developed in the form of health products to provide wider and longer-lasting beneficial effects, such as in the form of mouthwash. The purpose of this study was to determine the difference in pH of the manalagi apple peel extract mouthwash formulations in formulations A (25%), B (30%), and C (35%), and their potential benefits for dental health. The research design is a laboratory experiment with a completely randomized design. The intervention in the study was the addition of apple peel extract, including a concentration of 25% (formulation-A), 30% (formulation-B), and 35% (formulation-C). Each concentration was carried out 3 times. The results showed differences in pH in the mouthwash formulation of manalagi apple peel extract in formulations A, B and C, with a statistical test value of ρ-value 0.004 < (0.05). The pH of the manalagi apple peel extract mouthwash formulation was in the range of values of 4.1–4.4. Formulation C is the highest pH formulation and is stable in storage. The study concludes that there are significant differences in pH in the mouthwash formulation of manalagi apple peel extract in formulations A, B and C, and that the mouthwash formulation has the potential to be developed to improve cosmetic function, namely whitening teeth, and therapeutic functions, namely inhibiting the growth of bacteria and cleaning plaque and debris from the tooth surface.
