Advantage:
1.completely friendly to environment
2.excellent function and high calcium exchange ability (400min), better than STPP
3.excellent PH buffering capacity
4.competitive price to reduce much cost
5.free flowing
6.low density. 0.48/ml around. it is close to that of detergent powder
7.very suitable for high tower sprayer and especially dry mix or blending
8.be used same as STPP in producing process, without any change in equipment

Application:
CSDS is widely used as STPP Substitute in detergent powder making such as:
concentrate detergent powder,
ordinary detergent powder,
phosphorus-free washing powder,
low phosphorus detergent powder,
metal-washing powder.

Test method:
1.calcium exchange ability
General principle
Quantitative Ca2+ solution react with CSDS fully at a controlled condition, residue Ca2+ is mensurated by EDTA-Na2 titration and Eriochrome Black T (EBT) as as indicator. Then we calculate the Calcium exchange ability of CSDS
formula: E=(S-F)/M
E---Calcium Exchange Ability (mgCaO/gCSDS)
E= ( S-F)/M
S--- CaO weight, mgCaO
S= 56 X W/111 X 1000,
W-CaCl2 weight used
F---residue CaO content after test ( mg CaO)
F= ( V1-V2) X N X 28.04 / (5/100)
N- accurate concentration of EDTA-Na2 (N)
