Product Q&A

Q:What is the purity level of this STPP?

The purity of Na5P3O10 is 94.0% min, with P2O5 at 56.5% min and low impurities like iron and water insoluble content.

Q:How does STPP function in detergent?

It softens hard water by reacting with metal ions, enhances emulsifying power, buffers pH to 9-9.5, and prevents caking by absorbing moisture.

Q:What is the actual shelf life of the product?

While the COA lists 2 years, the real shelf life is much longer if stored in sealed bags away from direct sunlight, moisture, and incompatible chemicals.

Q:What are the main applications of this product?

Main applications include water softening in detergents, food industry quality modification, paper making, oil drilling mud dispersing, and ceramic/mining industries.

Q:What is the difference between Phase I and Phase II?

They have the same chemical properties but different crystal structures. Phase I hydrates faster, releases more heat, and is more prone to caking during dissolution.
