Sodium Percarbonate is used as an active oxygen component in detergents, bleaches and cleaning agents. Due to the unsatisfactory storage stability of the uncoated Sodium Percarbonate in warm/moist surroundings and in the presence of certain detergent and cleaning agent components, Sodium Percarbonate must be stabilized against the loss of active oxygen. An essential principle of stabilization involves encasing the Sodium Percarbonate particles in a coating of components having a stabilizing action. Here comes the definetion: the coated Sodium Percarbonate is the Sodium Percarbonate crystals coated with single or multiple layers of various substances in order to increase active oxygen stability and optimize storage and ensiling properties.
Coated Sodium Percarbonate is the more commonly commercialized peroxide compared with the uncoated Sodium Percarbonate. But the uncoated product is still the preferred ingredient for simply mixing with enough quantity of soda ash and some surfactants to form the popular oxygen bleaches.
