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.
本发明提供了一种用于漂白的氧化催化剂,该催化剂含有组分(a),该组分是由配位小于或等于5位的螯合剂和/或螯合剂引起的阴离子;组分(b),该组分是铜和/或锰化合物;和粘合剂化合物(c);过氧化氢基化合物(d),该化合物溶于水并产生过氧化氢,漂白组合物包含颗粒状产品或模塑产品,其中至少将组分(b)和组分(c)颗粒化或模塑在一起。根据本发明,可以使用一种氧化催化剂,它能以微量的成分促进过氧化氢基化合物的氧化作用,并具有抑制过氧化氢基化合物分解和抑制催化剂本身着色的优异效果,还可以使用含有该氧化催化剂的漂白组合物。
