WhatsApp Us About Sodium Pyrophosphate
1. Product Overview
Sodium Pyrophosphate, also known as Tetrasodium Pyrophosphate (TSPP), is a multifunctional inorganic phosphate used as a dispersant, sequestrant, buffer, and water-softening agent.
Industrial-grade TSPP is widely used in detergents, ceramic and tile production, metal surface treatment, water-based paints, and other industrial formulations.

2. Key Industrial Applications of Sodium Pyrophosphate
2.1 Detergents & Cleaning Products
In detergent formulations, industrial TSPP functions as:
- Water softener: binds calcium and magnesium ions to improve washing performance
- Dispersant: prevents dirt and soil from re-depositing on surfaces
- pH buffer: helps maintain alkaline pH in heavy-duty cleaners
2.2 Ceramic & Tile Production
In ceramic slip, glaze, and tile production, sodium pyrophosphate is used as a dispersant and deflocculant, helping:
- Improve slurry fluidity and stability
- Reduce water demand for a given viscosity
- Enhance particle dispersion and uniformity
If you are also using STPP or SHMP in ceramic applications, you can refer to:
Application of STPP in Ceramic Industry and Sodium Hexametaphosphate in Ceramics.
2.3 Metal Treatment & Surface Cleaning
Sodium Pyrophosphate is commonly used in:
- Metal cleaning and degreasing formulations
- Electroplating baths and surface preparation
- Rust-removal and phosphating auxiliary systems
It helps remove oils and oxides while providing buffering and dispersing effects in alkaline cleaning processes.
2.4 Water-Based Paints, Inks & Other Industrial Systems
In water-based coatings, inks, adhesives, and other systems, TSPP can act as a dispersant and stabilizer, contributing to:
- Better pigment dispersion
- Improved storage stability
- More uniform film formation

3. Usage Recommendations (Reference)
The following ranges are for reference only. Actual dosage should be verified through lab testing and adjusted according to your formulation and equipment.
- Detergents & cleaners: used as part of the total builder/dispersant package
- Ceramic & tile slurries: low-level dispersant dosage to optimize fluidity
- Metal cleaning: combined with alkaline builders and surfactants
- Coatings / inks: dosage adjusted based on pigment volume and system pH

6. Frequently Asked Questions About Industrial TSPP
Q1: What is the difference between industrial and food-grade Sodium Pyrophosphate?
Industrial-grade TSPP is designed for detergents, ceramics, metal treatment, and other technical applications, while food-grade is produced under stricter specifications and hygiene controls for use in foods.
If you need food-grade, please specify clearly so we can recommend the correct product.
Q2: Can TSPP be used together with STPP or SHMP?
Yes. In many formulations, Sodium Pyrophosphate is used in combination with STPP, SHMP, and other phosphates to balance sequestration, dispersion, pH control and cost-performance.
Q3: How can I get a quotation and a sample?
Please send us your required grade, use application, annual demand, packaging preference, and destination port.
We will provide COA, TDS, and the best available FOB / CIF offer.
