- Bleach activators are important components in compact detergents, Stain removal salts and machine dishwashing detergents. They already enable at 40-60 ° C a bleaching result comparable to that of hot laundry by using Hydrogen peroxide donors (mostly perborates or percarbonates) under Release organic peroxycarboxylic acid react.
- the achievable bleaching result is determined by the type and reactivity of the Peroxycarboxylic acid formed, the structure of the bond to be hydrolyzed as well as the water solubility of the bleach activator. Since it's mostly one reactive ester or an amide, it is necessary in many cases for it to use the intended area of application in granulated or coated form, to hydrolysis in the presence of alkaline detergent ingredients prevent and ensure adequate storage stability.
