Tetrasodium Pyrophosphate (TSPP), also known simply as Sodium Pyrophosphate, is a powerful alkaline phosphate used to emulsify proteins in meat, control tartar in toothpaste, and chelate magnesium in detergents.
As a manufacturer, Goway Chemical helps buyers distinguish between the various pyrophosphates to ensure the right functionality for your formulation.

TSPP increases the pH and ionic strength, allowing the meat protein (myosin) to hold more water
Crucial Distinction: TSPP vs. SAPP
The term “Sodium Pyrophosphate” causes confusion. It is vital to specify whether you need the Alkaline form (TSPP) or the Acidic form (SAPP).
| Feature | TSPP (Tetrasodium Pyrophosphate) | SAPP (Sodium Acid Pyrophosphate) |
|---|---|---|
| Formula | Na₄P₂O₇ | Na₂H₂P₂O₇ |
| pH Value | Alkaline (10.0 – 10.8) | Acidic (3.5 – 4.5) |
| Main Use | Meat Emulsification, Detergent Builder | Baking Powder (Leavening Agent) |
Key Applications of TSPP
1. Food Industry (Meat & Alternatives)
In meat processing (sausages, ham, nuggets), TSPP acts as a protein modifier. It increases the pH and ionic strength, allowing the meat protein (myosin) to hold more water.
- Benefit: Improves texture (snap/bite) and prevents water loss during cooking.
- Plant-Based Meat: Essential for mimicking the texture of real meat in vegan alternatives.
2. Toothpaste (Oral Care)
TSPP is the active ingredient in “Tartar Control” toothpastes. It works by removing Calcium and Magnesium from saliva, preventing them from depositing on teeth as calculus (tartar).
3. Detergents & Water Treatment
As an excellent water softener, TSPP prevents dirt re-deposition on clothes and emulsifies oils, making it a staple in industrial cleaning agents.

FAQ about Sodium Pyrophosphate
Is TSPP safe in food?
Yes. TSPP is recognized as GRAS (Generally Recognized As Safe) by the FDA and approved as E450(iii) in the EU, provided it is used within the recommended limits.
Can I use TSPP for baking?
No. TSPP is alkaline and will not react with baking soda to create lift. For baking, you need SAPP (Sodium Acid Pyrophosphate).
