Function in detergent system
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) | ||
| Full name | Sodium Tripolyphosphate | 4A Zeolite | Natural Zeolite | Activated Poly Sodium Metasilicate | Modified Sodium Disilicate |
| Appearance | White fine powder | White powder | White granular powder | ||
| Whiteness | 90 min | 95 min | 80 min | 85 min | 85 min |
| Odor | No odor | No odor | No odor | No odor, but irritant to nose and eye | |
| Bulk denstiy | 650~950 g/L | 550~700 g/L | 1100~1300 g/L | 350~600 g/L | 480~600 g/L |
| Loading qty | 25~26mt/20fcl | 20mt/20fcl | 27mt/20fcl | 27mt/40HQ | |
| Effect | Best | Normal | Bad | good | |
| Main content | Na5P3O10 94% min | Na2O.Al2O3 | N/A | Na2O + SiO2 74% min | Na2O2SiO2 |
| Ca exchange | 158 mg/g | 295mg/g | N/A | 320 mg/g | 550 mg/g |
| Mg exchange | N/A | 175 min | N/A | 330 mg/g | N/A |
| pH | 9.2~10.3 | 11.0 max | 11.3 max | 11.0 max | 12.0 max |
| Identical index | P2O5 content | Al3+ content | N/A | Na2O + SiO2 content | SiO2 content |
| Value of identical index | 56.5% min | 18% min | N/A | 75% min | 25% min |
| Water insoluble | 0.1% max | 100% | almost 100% | 1.5% max | 1.5% max |
| Moisture | 0.5% max | 22% max | 16% max | N/A | 5% max |
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)
