Disclosed is an oxidizing system comprising a macrocyclic metal complex, an oxidizing agent and an oxidation-enhancing compound. This oxidizing system is useful under a wide variety of reaction conditions for oxidizing oxidizable substances by contacting the oxidizable substance with the specific oxidizing system. An example of a possible use is in a process for removing excess, unfixed dye from textile materials after a dyeing.
