Description

Product Description

【Product Introduction】

Disodium phosphate powder is usually a white crystalline powder with a relative density of 1.52 and a melting point of 35.1°C. Disodium phosphate powder is easily soluble in water, and its aqueous solution is weakly alkaline. It can decompose at high temperatures to produce phosphoric acid gas and water vapor. This property makes it widely used in wood flame retardant formulations and can effectively inhibit wood combustion.

【Product Advantages】

Good Solubility
Disodium phosphate powder has high solubility in water. At 25℃, its solubility in water is about 7.7g/100mL. It can be quickly and evenly dispersed in many chemical reactions or industrial production processes that need to be carried out in solution, providing convenient conditions for subsequent reactions or operations.

Wide Industrial Applicability

Food grade Disodium Phosphate Powder (CAS No.: 7558-79-4) is usually applied to food additive, which is widely used in food processing. It is mainly used as an acidulant, leavening agent, flavoring agent, etc., and can be used to regulate the pH value and stability of food.

Disodium Phosphate Powder can help food maintain taste and color, prolong shelf life, and enhance the taste in food additives.

In addition, Disodium Phosphate Powder can also promote the leavening effect of bread, cakes and other bread products, making them softer and more delicious. The application of food-grade disodium hydrogen phosphate in food addition is positive, which helps to improve the quality and taste of food, and meets national food safety standards.
