  • Patent number: 5380458
    Abstract: The present invention provides for dilute aqueous hypohalite solutions stabilized against decomposition catalyzed by copper ions present in said solution containing a small amount of a multidentate heteroaromatic stabilizer compound including the general structure selected from: ##STR1## wherein Ar is comprised of carbon or carbon and nitrogen atoms sufficient to form a 5 or 6 membered aromatic ring or at least one other ring condensed with said 5 or 6 membered aromatic ring, X is selected from the group consisting of nitrogen or carbon which form part of an aromatic ring structure and oxygen, and Y is nitrogen or carbon which form part of an aromatic ring structure.This invention also provides stable hypohalite-containing aqueous bleach, detergent and disinfectant formulations which retain hypohalite stability even after further dilution with copper-contaminated water.
