Applications by Industry
1) Detergents & Cleaning Products
Industrial STPP is a classic builder that softens water and improves detergency performance.
Value point: reduces surfactant cost by 8–12% through water softening and better cleaning efficiency (formulation dependent).
- Sequesters Ca2+/Mg2+ to improve surfactant efficiency
- Supports soil suspension and reduces redeposition
- Contributes alkalinity and formulation stability
2) Ceramics, Tiles & Glaze
Used as a deflocculant / dispersant to reduce water demand and control viscosity in ceramic slurries.
Value point: can lower slurry moisture by 7–10%, helping reduce drying energy (system dependent).
3) Industrial Water Treatment
Acts as a sequestrant and dispersant to reduce scale risk and manage hardness ions.
Value point: phosphate programs may help control CaCO3 scale at 2–10 ppm in suitable systems (chemistry dependent).

4) Concrete & Building Materials
Can be used in certain admixture systems to help control water retention and rheology, supporting workability and performance.

FAQ: Industrial STPP Bulk Supply
What’s the lead time for a bulk order of Industrial STPP?
Typical production lead time is 7–14 days after PO confirmation. Actual schedule depends on quantity, packing type, and shipping mode (FCL/LCL).
Can you provide COA, SDS (MSDS), and a specification sheet?
Yes. We provide batch COA, SDS (GHS), and TDS/spec sheet upon request. Destination-specific files can be prepared as needed.
What is the difference between industrial-grade and food-grade STPP?
Industrial-grade STPP is for non-food processes (detergents, ceramics, water treatment, etc.) and may have a different impurity control profile.
Do not use industrial grade in food. For edible applications, use food-grade STPP and request FCC/E451i documentation.
What packaging options do you offer for wholesale shipping?
Common options include 25 kg moisture-proof bags, 50 kg heavy-duty bags, and 1000 kg jumbo bags. FCL/LCL shipping is available.
