  A method for detecting the onset of ovulation in a female mammal is provided. The method comprises contacting mouth air of the female mammal with an arylmethane test chromogen in an amount effective to undergo a rapid and detectable color change in the presence of one or more volatile sulfur compounds. The color of the test chromogen is compared to a control color that corresponds to a pre-ovulatory sulfur content. The difference in color between the test chromogen and the control color is correlated to the onset of ovulation.

  A color changing soap dispenser having a reservoir and a pump. The reservoir contains a color changing soap. The color changing soap contains a soap composition comprising water and a surfactant, an indicator dye which exhibits an observable color change at a color change pH, and a base selected from the group consisting of carbonate salts of group I and II elements, phosphate salts of group I and II elements, bicarbonate salts of group I and II elements, and hydroxide salts of group I and II elements. The color changing soap has a pH of greater than 7 and less than 13. The method of using the color changing soap is also disclosed.
