Product Q&A

Q:What is the main application of MSD?
A:
MSD is primarily used to replace STPP in detergent powder formulations, offering a lower price and no phosphorus pollution to water systems.
Q:What are the key chemical properties of MSD?
A:
MSD has a purity of 95%, Ca2+ exchange capacity of 550 min mg/g, Mg2+ exchange capacity of 100 min mg/g, and SiO2 content of 25% min.
Q:Can MSD completely replace STPP?
A:
No, MSD cannot completely replace STPP because STPP enhances emulsifying and dispersing power and acts as an anti-caking agent by absorbing moisture.
Q:What is the shelf life of MSD?
A:
The COA lists a 2-year shelf life, but the actual shelf life is much longer if stored in sealed bags away from sunlight, moisture, and incompatible chemicals.
Q:What are the physical characteristics of MSD?
A:
MSD appears as a white granular powder with a bulk density of 0.35-0.45 g/cm3 (granular) or 0.48-0.60 g/cm3 (fine solid) and whiteness of 85% min.
