Product Q&A

Q:What is the purity of this STPP product?

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

Q:How does STPP function in detergent?

It softens hard water by reacting with metal ions, buffers pH to 9-9.5, prevents caking, and enhances the emulsifying and dispersing power to remove dirt effectively.

Q:What are the main applications of this product?

It is primarily used as a water softener in the detergent industry, and also serves as a quality modifier in food, a dispersing agent in oil drilling, and in paper, ceramic, mining, and water treatment industries.

Q:What is the shelf life of the product?

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

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 compared to Phase II.
