2. Key Industrial Applications of STPP
2.1 Detergents & Cleaning Products
Industrial STPP is a classic builder in detergent formulations. It helps:
- Soften water by binding calcium and magnesium ions
- Improve surfactant performance and overall cleaning power
- Prevent redeposition of dirt on fabrics and hard surfaces
- Stabilise pH and maintain formulation stability

2.2 Ceramics, Tiles & Glaze
In the ceramic industry, industrial STPP is used as a deflocculant, dispersant and water reducer for ceramic body, glaze and slurry:
- Improves slurry fluidity and reduces water demand
- Prevents particle agglomeration and enhances dispersion
- Helps stabilize glaze flow rate and surface smoothness
- Supports energy-saving and cost reduction in production
