CAS 7758-29-4 White Granular Sodium Tripolyphosphate for Dyeing Acid, Technical Grade Purity 99.4% STPP for Detergent
1. Product Introduction
White granular purity 94% sodium tripolyphosphate, commonly abbreviated as STPP, is an inorganic compound that plays a vital role in various industries and applications. It belongs to the family of polyphosphates and is composed of sodium cations (Na+) and tripolyphosphate anions (PO₃³⁻). This versatile substance is widely used for detergents, waste water treatment softner, food preservation, and various industrial processes.

3. White Granular Purity 94% Sodium Tripolyphosphate Application
Sodium tripolyphosphate function in detergent industry:
STPP is a good auxiliary in detergent industry, the usual dosage is about 10~35%, the function of STPP in detergent system are:
1. Soften the hard water by reacting with metal ions of Ca2+, Mg2+, Fe3+ and others to make them from insoluble to soluble Na5P3O10+Ca2+ ---> Na3(CaP3O10)+2Na+
2. Enhancing the emulsifying and dispersing power, to increase the solubility of protein and dust which normally existing in the fabrics from daily life
3. Buffering agent, to make the pH value of detergent solution on the level of 9~9.5, so that those acid dirt can be easily removed from fabrics
4. Anti-caking agent for detergent powder. Since detergent powder is easily caking in exposed air, STPP can absorb the moisture and become Hexahydrate, which is dry and free flowing.
White granular sodium tripolyphosphate for dyeing acid:
1. Ion exchange agent
Sodium tripolyphosphate can serve as an ion exchange agent to adsorb dyes onto fiber surfaces, thereby enhancing the adhesion and permeability of dyes. Better penetration of dyes into the interior of fibers improves dyeing uniformity.
2. Complex agent
Sodium tripolyphosphate can form complexes with metal ions, reducing the impact of impurity metal ions on dyeing and improving color fastness.
3. Prevent pollution and sedimentation
Sodium tripolyphosphate can effectively prevent pollutants from migrating to the surface of fibers and reduce the precipitation of dyes during the dyeing process, thereby making the dyeing results more aesthetically pleasing.
