CSDS is widely used as STPP Substitute in detergent powder making advantages: a.CSDS is the best in current phosphorus-free detergent builders, the function is almost same as STPP. It is the best replacement of STPP at present b.CSDS is completely friendly to earth while STPP caused serious pollution. c.CSDS has an excellent solubility in water,even cold water, better than STPP. xxxxx price of CSDS is much lower than that of STPP e.CSDS can be used same as STPP in producing process, without any change in equipment specification and COA ITEM INDEX TEST RESULT Calcium exchange capacity >=400 mgCaCO3/gCSDS: 431.06 Humidity: <=5% 2.5 PH value: <=12 11.27 SiO2: >=20% 23.08 Whiteness: >=80% 87.99 Solubility: fully soluble FULLY SOLUBLE Visual specific weight: 0.25-1
