  • Composition and process for washing and bleaching
    Patent number: 4326976
    Abstract: Particulate washing and bleaching compositions containing a peroxy compound and an alkali carbonate have their tendency to cake during storage reduced by incorporating within the compositions an alkaline aryl sulphonate, such as sodium methyl naphthalene sulphonate, and a water-insoluble inorganic compound, such as magnesium trisilicate. The compositions can be used for washing and bleaching textiles and fibers and cleaning hard surfaces.
