Sodium Tripolyphosphate Price & Suppliers in India

Sodium Tripolyphosphate (STPP) is a white, odorless inorganic salt with the chemical formula Na5P3O10. It is produced by the calcination of a mixture of disodium phosphate and monosodium phosphate. In the Indian market, it is primarily valued for its high sequestering capacity, which allows it to bind metal ions like calcium and magnesium, effectively softening water.

In India, STPP is a cornerstone chemical for the detergent industry, where it acts as a builder to enhance cleaning performance. Beyond detergents, it serves critical roles in the textile industry for bleaching, in paper mills as a dispersant, and in the water treatment sector to prevent scale formation in industrial pipelines and boilers. Its food-grade variant is also highly sought after for moisture retention in processed seafood and meat.

When procuring STPP in India, buyers should prioritize suppliers who provide consistent batch-to-batch purity and low heavy metal content. It is advisable to verify the 'P2O5' content and the 'Water Insoluble' percentage, as these directly impact the performance of the final formulation. Ensure that the packaging is moisture-proof, as the product is hygroscopic and prone to caking in humid Indian climates.
