BIS Certification for Sodium Tripolyphosphate Anhydrous – Process, Fees & Docs

Updated on August 02, 2025 04:15:09 PM

Sodium Tripolyphosphate (STPP) with the molecular formula NA5P3O10 is a versatile inorganic compound that finds its application in Detergent, Food Industries, Food Preservation, and Ceramic Industries. This is especially important in cases when the technical grade STPP is used because, being in its anhydrous form, it is both pure and highly effective. QCOS for STPP in India has been set by the Bureau of Indian Standards (BIS), to check the quality of STPP so that its usage in industrial applications remains safe.

It includes requirements for the manufacturing process, performance characteristics, methods for implementation, and labeling, all with the intention of enhancing the quality of the products and thereby protecting the consumer. While industries demand products meeting regulatory benchmarks deem it compulsory for industries specifically those involved in the production of STPP to understand the entire process of certification.

This blog will focus on analyzing Sodium Tripolyphosphate Anhydrous, namely the manufacturing process and performance, testing methods, as well as BIS certification as a necessity for the Indian market. Whether one is a manufacturer, supplier, or consumer, such information on the above areas will be useful in improving a general understanding of this important compound and its uses.

What is the Sodium Tripolyphosphate, Anhydrous, Technical?

Na5P3O10, sometimes called tripolyphosphate. However, it is a sodium salt of polyphosphate and is used in many fields such as detergents, food industries, and ceramics. STPP is manufactured in India in its anhydrous form as well as the hydrated form although the anhydrous type is crucial for technical uses. The STPP has its quality control standards (QCOS) set by the Bureau of Indian Standards (BIS) to guarantee its safety in use among industries.

Testing Methods for Sodium Tripolyphosphate

Here are given some Testing Methods for Sodium Tripolyphosphate-:

Chemical Analysis:

This is done by titration to estimate the concentration of phosphate molecules present and ion chromatography to determine sodium concentration.

Physical Tests:

Particle size distribution and moisture content are determined by sieve analysis and a method that measures the weight loss as a function of temperature, known as thermogravimetric analysis (TGA).

Solubility Tests:

These measurements identify the extent to which STPP dissolves in water so as to provide optimal performance in uses such as detergents.

These testing methods must be done by accredited laboratories to meet BIS standards, thus it is important to develop standard laboratorie.
