Basic Information and Parameters

High Quality Sodium pyrophosphate decahydrate, with the CAS number 13472 - 36 - 1, is a white crystalline powder. It has a molecular formula of Na₄P₂O₇·10H₂O and a molecular weight of approximately 446.06 g/mol. This product is highly soluble in water, and its aqueous solution is alkaline. It has good stability under normal storage conditions, but it should be kept away from moisture and acidic substances.

Product Uses

Sodium pyrophosphate decahydrate has a wide range of applications in various industries:

1. Food Industry: It is used as an emulsifier, stabilizer, and sequestrant. In processed meat products, it helps to improve the water - holding capacity, prevent the oxidation of fats, and maintain the texture of the meat. In dairy products, it can prevent the coagulation of milk proteins and improve the stability of the product.
2. Industrial Cleaning: Due to its excellent chelating ability, it can be used as a component in detergents. It can chelate metal ions such as calcium and magnesium in hard water, preventing the formation of scale and improving the cleaning effect.
3. Textile Industry: It is used in textile dyeing and finishing processes. It can adjust the pH value of the dyeing bath, improve the solubility of dyes, and enhance the dyeing effect. It also helps to remove impurities from the fabric surface during the scouring process.
4. Water Treatment: As a water - softening agent, it can remove heavy metal ions in water and prevent the formation of precipitates in water treatment systems.

How to Use the Product

The usage method of sodium pyrophosphate decahydrate depends on its specific application:

• Food Industry: When using it in food production, it should be added in accordance with the relevant national food additive standards. Usually, it is first dissolved in a small amount of water and then added to the food mixture under stirring. The dosage is generally determined according to the type of food and the desired effect.
• Industrial Cleaning: In detergent formulations, it can be directly added to the detergent powder or liquid. The recommended dosage is 5% - 15% of the total detergent mass. When using it for cleaning, it should be dissolved in water at an appropriate concentration according to the degree of dirt.
• Textile Industry: In the dyeing process, it is added to the dyeing bath at a certain concentration. The specific dosage needs to be determined according to the type of fabric, dye, and dyeing process. In the scouring process, it is used in combination with other scouring agents to achieve better results.
• Water Treatment: When used for water treatment, it is usually added to the water in a dissolved state. The dosage is determined according to the water quality, such as the content of heavy metal ions and the hardness of the water.

Detailed Use Cases

Case 1: Meat Processing

A meat processing company used sodium pyrophosphate decahydrate in its pork sausage production. By adding 0.3% of this product to the meat mixture, they found that the water - holding capacity of the sausage increased significantly. The sausage had a more tender texture and less water loss during cooking. In addition, the shelf - life of the sausage was also extended due to the anti - oxidation effect of the product.

Case 2: Detergent Production

A detergent manufacturer added 10% sodium pyrophosphate decahydrate to its laundry detergent formula. After market testing, it was found that the detergent showed better cleaning performance, especially in hard water areas. The product could effectively prevent the formation of scale on clothes and washing machines, and the cleaning effect was significantly improved compared with the previous formula without this ingredient.

Case 3: Textile Dyeing

In a textile dyeing factory, when dyeing cotton fabrics with reactive dyes, they added an appropriate amount of sodium pyrophosphate decahydrate to the dyeing bath.
