Definitions
- the present invention relates to a bleach-enhancing active ingredient combination, the one Transition metal salt, an ammonium salt and an oxidizing agent contains a method to produce such a combination of active ingredients, the use of such Active ingredient combination for enhancing the bleaching effect of, in particular, inorganic Peroxygen compounds, especially when bleaching colored ones Soiling on hard surfaces, and detergents for hard surfaces contain such an active ingredient combination.
- Inorganic peroxygen compounds especially hydrogen peroxide and solid peroxygen compounds, which dissolve in water to release hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have long been used as oxidizing agents for disinfection and bleaching purposes.
