Definitions

  • Bleach activators are important components in compact detergents, stain salts and machine dishwashing detergents. They allow you to start at 40 ° C to 60 ° C the bleaching result comparable to that of the hot laundry by using Hydrogen peroxide donors (mostly perborates or perearbonates) with release an organic peroxycarboxylic acid react.
  • the achievable bleaching result is determined by the type and reactivity of the formed Peroxy carboxylic acid, the structure of the bond to be hydrolyzed, and the Water solubility of the bleach activator.
  • Many substances are of the state of the art Technique known as bleach activators.
