Product Q&A

Q:What is the purity of this Sodium Tripolyphosphate?

The purity of Na5P3O10 is 94.0% min, with P2O5 at 56.5% min and low impurities.

Q:What are the main applications of STPP?

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

Q:How does STPP function in detergent systems?

It softens 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 shelf life of the product?

The COA lists 2 years, but the actual 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 STPP?

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