ABSTRACT:
The present invention provides a hydrogen peroxide indicator and a peracetic acid indicator that include a substrate on which is disposed an indicator composition that includes at least one of a select group of colorants and a transition metal salt. As a result of exposure to hydrogen peroxide and/or peracetic acid, the colorants change color, and even become colorless, thereby providing an indication of the presence of hydrogen peroxide and/or peracetic acid.
