Bleach activators are compounds that react with hydrogen peroxide in aqueous solution to form peroxy acids. Peroxy acids are more active bleaches than hydrogen peroxide at lower temperatures (<60 °C).
 Bleach activators are a component of most laundry detergents.
 The most common bleach activators used commercially are tetraacetylethylenediamine (TAED) and sodium nonanoyloxybenzenesulfonate (NOBS).
 NOBS is the main activator used in the U.S.A. and Japan.
 TAED is the main activator used in Europe.
