Appearance: white granular powder
Characteristic:1. 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:
2. MSD 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
