Personal care products with visual indicator of vaginitis
View Patent ↗There is provided a personal care product having a body side liner, a baffle and an indicator strip with two ends. The indicator has an amine sensitive dye near at least one end. The indicator extends from the target area just below the liner to just above the baffle such that the dye deposit is visible to an unaided eye. The dye changes color in the presence of amines which are characteristic of infection, thus alerting the user to the possibility of infection. Such an indicator placed in a feminine hygiene pad, for example, may be useful in the diagnosis of vaginits.
