Abstract (en)
[origin: WO9313113A1] The invention concerns a method of reducing the colour of surface-active compounds by carrying out a bleaching reaction with peroxy compounds in the presence of bleach boosters selected from the group consisting of alkaline-earth ions, zinc ions and/or alkali-metal silicates.
