Abstract: This invention concerns a detergent composition in solid form containing surfactant and a peroxide bleaching agent. In another preferred composition, encapsulated or non-encapsulated enzymes may be present, improving performance during washing. Other conventional additives may also optionally be present. The composition is suitable for hand washing and soaking of clothing. The process for the form relation of this composition is furthermore fundamental in order to ensure the stability of the peroxide bleaching agent and the enzyme. For this reason, low moisture materials and hydrating salts are used.
