To replace STPP in detergent formulation, with lower price and no phosphors pollution to water system
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:
| Index | STPP | ZEOLITE | APSM | MSD | |
| Synthetic | Natural | (also called PSM,PSMA) | (also called 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
3. We normally list 2 years as the shelf life in our COA, the real shelf life is actually much longer than 2 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials)
LK (Nanjing) Co., Ltd. Is the initial member of the brand name RAWCHEM, established in 2008, served as the representative office of an European comprehensive trading company in its early years, mainly dealing with the import and export business of raw chemical materials for the detergent industry, now we have become an industrial company, focused on the detergent industry.
