Abstract:
     The invention relates to a chemical washing powder which is prepared with surfactant and detergent aid as main raw materials. In view of the high cost, poor availahility and pollution problems of using sodium tri-poly-phosphate as the main constituent of the detergent aid, a method and recipe of adding tri-sodium phosphate (Na3PO4) to substitute a part of sodium tri-poly phosphate and adding other water soluable inorganic salts to prepare a mixed detergent aid has been presented. This invention has not only remarkably improved the cleaning effect of the washing powder, but also cut down its cost; besides an abundant source of raw material has been found. The present invention concerns also the method of preparing the free flowing sodium tripoly-phosphate suitable for production of the washing powder.
