Tetrasodium Pyrophosphate (TSPP) for Toothpaste & Food

Product Introduction

Tetrasodium pyrophosphate (TSPP), also known as sodium pyrophosphate (chemical formula Na₄P₂O₇, E450(iii)), is a white, free-flowing, water-soluble phosphate salt. It is not the same as tetrasodium phosphate or sodium phosphate, which are different compounds, though buyers often compare them.

The ingredient is best known for its role in tetrasodium pyrophosphate toothpaste formulations. In tartar-control oral care, TSPP helps keep calcium from forming hard deposits on the teeth. It is also a trusted functional ingredient in meat, seafood and dairy processing.

As a professional TSPP manufacturer, supplier and exporter in China, WEHENGFOOD supplies consistent, high-purity TSPP for toothpaste producers, meat processors, dairy manufacturers and ingredient distributors worldwide. We offer both toothpaste-grade and food-grade TSPP, with stable quality, flexible packaging and reliable export service.

Functions

Tartar control: binds free calcium and magnesium ions in saliva and plaque, slowing the crystallization that turns soft plaque into hard tartar.
Stain control: limits mineral deposits on the tooth surface, which helps reduce the build-up that traps stains.
Water retention: helps meat and seafood hold moisture through cooking, freezing and thawing, improving yield and juiciness.
Protein binding and emulsion stability: helps dissolve muscle proteins and keeps fat and water evenly dispersed in the product.
Sequestering and buffering: captures metal ions that cause oxidation and discoloration, and stabilizes pH.
Texture and shelf life: supports a tender bite, better color and longer storage stability.

Applications

Oral care (key application)

Tetrasodium pyrophosphate in toothpaste: the core ingredient in tartar-control and whitening toothpaste, compatible with silica abrasives and fluoride.
Anti-tartar mouthwash and other dental care products.

Meat and seafood

Burgers, ham, sausages and hot dogs, for juicier texture and higher cooking yield.
Peeled shrimp, canned tuna and smoked fish, for better moisture retention and firmer bite.

Dairy

Processed cheese, for smoother melt, better slice structure and stable emulsification.
Milk beverages, for pH buffering, calcium binding and shelf-life support.
Ice cream, for a smoother texture and less icing.

FAQ

Q1: What is tetrasodium pyrophosphate (TSPP)?

Tetrasodium pyrophosphate (TSPP), also known as sodium pyrophosphate (Na₄P₂O₇, CAS 7722-88-5, E450(iii)), is a white, water-soluble phosphate powder. It is mainly used as a tartar-control agent in toothpaste and as a water-retention and texture improver in meat, seafood and dairy products.

Q2: Why is tetrasodium pyrophosphate used in toothpaste?

TSPP in toothpaste binds calcium and magnesium ions in saliva and plaque. This slows the crystallization that turns soft plaque into hard tartar, so it is a core ingredient in tartar-control and whitening toothpastes. It also works well with silica abrasives and fluoride.

Q3: Does TSPP toothpaste remove existing tartar?

No. TSPP helps prevent new tartar from forming, but it does not dissolve tartar that has already hardened. Existing tartar needs professional dental cleaning, and TSPP helps keep it from building up again.

Q4: Is tetrasodium pyrophosphate safe in toothpaste and food?

TSPP is a permitted food additive (E450(iii)) and a long-established ingredient in oral care products. Safety depends on using the right grade at the right dosage, so always follow the regulations of your target market and the guidance on your supplier’s COA and specification sheet.

Q5: What is the difference between tetrasodium pyrophosphate, tetrasodium phosphate and sodium phosphate?

They are different compounds. TSPP (sodium pyrophosphate) contains two linked phosphate units and is used in toothpaste, meat and dairy. Tetrasodium phosphate and general sodium phosphate have different structures and properties, so they are not interchangeable with TSPP in a formula. Check the CAS number (TSPP is 7722-88-5) when sourcing.
