        "The pH of the environment of the perianal bacteria needs to be maintained in an acidic state such as at a pH less than about 5.5 ... in order to hinder the amine reaction that causes the unwanted fishy odor.",
        "Vinegar wipes, douches, and other acidic products have been proposed for personal cleansing, but such products have generally been developed for rapid cleansing and not for lasting control of pH.",
        "With the viscous carrier of many embodiments disclosed herein, acidifying components can be available for a prolonged period of time to effectively control the pH of the environment.",
        "The new recognition that vaginal bacteria are not cause of fishy odor in many women is of special significance, and helps explain why antibiotic treatments ... have fared so poorly."
