DILUTE AQUEOUS BLEACHING AGENT COMPRISING ALKALI(NE EARTH) METAL HYPOHALITE AND A HETEROAROMATIC COMPOUND CAPABLE OF FORMING MULTIDENTATE COMPLEXES WITH CU(II) IONS

摘要

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: IMAGE 1. IMAGE 2. IMAGE 3. 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.
