The invention relates to a liquid bleaching composition for catalytically bleaching substrates, especially laundry fabrics, with atmospheric oxygen or air. A liquid bleaching composition is provided comprising an organic substance which forms a complex with a transition metal, the complex catalysing bleaching of a substrate by atmospheric oxygen, and a liquid carrier or solvent, wherein the composition is substantially devoid of peroxygen bleach or a peroxy-based or -generating bleach system. Also provided is a method of bleaching a substrate comprising applying the liquid bleaching composition to the substrate. Also provided is a method of treating a textile by contacting the textile with the liquid bleaching composition, whereby the complex catalyses bleaching of the textile by atmospheric oxygen after the treatment.
本发明涉及一种用于催化漂白基材,特别是洗涤织物,使用大气氧气或空气的液体漂白组合物。提供了一种液体漂白组合物,其中包括一种有机物质,该有机物质与过渡金属形成复合物,该复合物通过大气氧气催化基材的漂白,以及液体载体或溶剂,其中该组合物基本上不含过氧化物漂白剂或过氧化物基或生成漂白系统。还提供了一种漂白基材的方法,包括将液体漂白组合物应用于基材。还提供了一种通过将液体漂白组合物接触织物来处理纺织品的方法,在处理后,复合物通过大气氧气催化织物的漂白。
