  • Patent number: 5935708
    Abstract: In order to increase active oxygen stability, sodium percarbonate is coated with single or multiple layers of various substances. Sodium percarbonate particles consist of a core of sodium percarbonate fluidized bed spray granulate and sodium sulphate, which may be partially hydrated, as the sole constituent of a single coating layer. The particles exhibit both elevated active oxygen stability and very good ensilability. The coating layer is applied by spraying an aqueous Na.sub.2 SO.sub.4 solution onto the particles to be coated, which were themselves produced by fluidized bed spray granulation, in a fluidized bed and vaporizing water at a fluidized bed temperature of 35 to 100.degree. C.

  • Patent number: 5759976
    Abstract: Tableted detergents are formed from a hydrated phosphate sequestrant, caustic, free water and, optionally, fillers by combining the products and tableting the components without permitting the tablets or detergent to exceed 50.degree. C. In a preferred embodiment where fillers are incorporated, all free water is combined with the phosphate sequestrants, both anhydrous and hydrated. After the water has been absorbed by the sequestrants, the filler and caustic can be added and the detergent tableted. The free water is bound sufficiently tightly to the phosphate sequestrant that it does not rapidly react with the anhydrous caustic, maintaining the temperature at less than 50.degree. C., which in turn prevents the water of hydration in the phosphates from reacting and thereby weakening the formed tablets. The tablets can also be formed by combining the filler with the phosphate sequestrants and water and subsequently adding caustic if the detergent is cooled and its temperature maintained below 50.degree. C.
