Oxidation catalyst for bleaching, and bleaching composition using the same

The present invention provides an oxidation catalyst for bleaching containing a component (a) which is an anion caused from a chelating agent having less than or equal to coordination position 5 and/or the chelating agent, and a component (b) which is a copper and/or manganese compound; and a binder...

Beschreibung
Zusammenfassung:	The present invention provides an oxidation catalyst for bleaching containing a component (a) which is an anion caused from a chelating agent having less than or equal to coordination position 5 and/or the chelating agent, and a component (b) which is a copper and/or manganese compound; and a binder compound (c); a hydrogen peroxide-based compound (d) which dissolves in water and generates hydrogen peroxide, the bleaching composition containing a granulated product or a molded product in which at least the component (b) and the component (c) are granulated or molded together. According to the invention, an oxidation catalyst that promotes the oxidation effect of hydrogen peroxide-based compounds with a trace amount of the composition, and has excellent effects of suppressing the decomposition of hydrogen peroxide-based compounds and suppressing coloration of the catalyst itself, and a bleaching composition containing the oxidation catalyst can be utilized.
