    摘要： A granular STPP suitable for detergent compositions which is non-caking in non-agitated water is produced by wetting anhydrous phase II STPP granules and drying the granules to remove free water. The resulting granules, when incorporated in detergent compositions, form a free flowing detergent slurry in detergent dispensing systems.

    摘要： Dense rotary dried sodium tripolyphosphate (STPP) particles having a bulk density of at least 0.9 g/cc and a particle size distribution of 0 to 85% by weight +20 mesh, 15 to 100% by weight -20 +100 mesh and 0 to 20% by weight -100 mesh are moisturized by adding a sufficient amount of water to produce a material containing on the average between about 10% and about 30% by weight moisture. The moisturized material is calcined to a temperature within the range of from about 300 to about 600°C, to produce a granular STPP product having low friability, high absorptivity and a bulk density within the range of from about 0.65 to about 0.87 g/cc.

    摘要： The method of prodycing sodium tripolyphosphate hexahydrate powder which comprises hydrating anhydrous sodium tripolyphosphates having a particle size such that at least 85% by weight is less than 150 µm with sufficient water to provide not more than 105% of the theoretical amount of water to form the hexahydrate, drying the sodium tripolyphosphate hexahydrate to remove substantially all of the un­combined water and maintaining said hydrating and drying steps at less than 80% thereby producing a sodium tripolyphosphate hexahydrate powder such that at least 50% by weight is less than 150 µm.
    It is particularly useful for use as a builder in a heavy duty detergent.
