Sodium perborate tetrahydrate is commonly used as a bleaching agent in detergent preparations. It is a stable solid that releases hydrogen peroxide when dissolved in water, which helps to remove stains and brighten fabrics. Sodium alkylbenzenesulfonate and sodium silicate are both used as surfactants and builders in detergents, but not as bleaching agents.
