| 摘要 |
The aim of the invention is to improve the production of a bleach-reinforcing combination of active agents that is obtained by intimately mixing a water-soluble salt of a divalent transition metal chosen from cobalt, iron, copper and ruthenium, and mixtures thereof, a water-soluble ammonium salt, and optionally, a peracid-based oxidizing agent, as well as an inert support material. This is achieved essentially by using the divalent transition metal salt in the form of an aqueous solution. |
