Characteristic:
1. To exchange Calcium and Magnesium capacity is higher than 4A Zeolite, it is equivalent to STPP, water soften speed is quick, soften capacity is strong and temperature scope is wide
2. Good compatibility with many kinds of surfactants(especially non-ionic surfactants), and with self-consistent stain removable ability
3. It is easy to dissolve in water, 100ml water can dissolve more than 20g
4. Good characteristic of penetrating, emulsifying, suspension and anti-sediment for stain, pH buffering capacity is strong too
5. It is applicable to the slurry preparation, post-blending etc process. The product has good whiteness, fluidity and stability
6. Environmental friendly

To replace STPP, meanwhile solve the Zeolite's disadvantages, we are now producing silicates series products: MSD and APSM, below is the comparison of the main indexes of STPP, Zeolite, APSM and MSD/CSDS: 

APSM can not completely replace STPP due to STPP's features of:
 - Enhancing the emulsifying and dispersing power, to increase the solubility of protein and dust which normally existing in the fabrics from daily life
 - Anti-caking agent for detergent powder. Since detergent powder is easily caking in exposed air, STPP can absorb the moisture and become Hexahydrate, which is dry and free flowing
