Product Q&A

Q:What is the purity level of this STPP?

The purity of Na5P3O10 is guaranteed to be 94.0% min.

Q:What are the main applications of STPP?

It is primarily used as a water softener in detergents, a quality modifier in food, and a dispersing agent in oil drilling and water treatment.

Q:How does STPP function in detergent systems?

It softens hard water by reacting with metal ions, enhances emulsifying power, buffers pH to 9-9.5, and acts as an anti-caking agent.

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

While listed as 2 years in COA, the real shelf life is much longer if stored in sealed bags away from sunlight and moisture.

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 may cause caking during dissolution.
