SELF INDICATING ANTIMICROBIAL CHEMISTRY

摘要

Self-indicating chemistries are provided for visual detection by a user of efficacious levels of peroxycarboxylic acid concentrations in a solution produced in situ. The self-indicating chemistries include a combination of dyes providing a visual color indication, such as a tri-color indicator system, such as a yellow, green, and red color system indicating in situ threshold levels of peroxycarboxylic acid concentrations in a solution employing the self-indicating chemistry. Systems, kits and compositions for a quantitative assessment of an in situ perhydrolysis reaction to generate peroxycarboxylic acids are provided. Methods of use are further provided.

1. A self indicating peroxycarboxylic acid chemistry composition comprising:
a peroxycarboxylic acid; a background dye; and a latent peracid selective dye(s) which upon oxidation by the peroxycarboxylic acid provides a visual indication the presence of a minimum concentration of peroxycarboxylic acid for efficacy as an antimicrobial.
