context_page_description: Bleach activators are compounds that allow a lower washing temperature than would be required otherwise to achieve the full activity of bleaching agents in the wash liquor. Bleaching agents, usually peroxides, are usually sufficiently active only from 60 °C on. With bleach activators, this activity can already be achieved at lower temperatures. Bleach activators react with hydrogen peroxide in aqueous solution to form peroxy acids, they are a component of most laundry detergents. Peroxy acids are more active bleaches than hydrogen peroxide at lower temperatures but are too unstable to be stored in their active form and hence must be generated in situ.
  The most common bleach activators used commercially are tetraacetylethylenediamine and sodium nonanoyloxybenzenesulfonate. NOBS is the main activator used in the U.S.A. and Japan, TAED is the main activator used in Europe.
