Bulk Disodium Hydrogen Phosphate Powder CAS 7558-79-4
Disodium Hydrogen Phosphate: Product Introduction
Disodium hydrogen phosphate, also known as sodium monohydrogen phosphate, is a common food additive belonging to the phosphate class. It is widely used in meat products, flour products, and dairy products. It regulates the acid-base balance of food, enhances the water-holding capacity of proteins, and makes meat more tender and dough more elastic. As a food-grade additive, its safety has been rigorously evaluated, and it is harmless to the human body when used in appropriate amounts. It is an indispensable auxiliary agent in modern food processing.
Disodium hydrogen phosphate VS Sodium dihydrogen phosphate
| Property | Sodium Dihydrogen Phosphate | Disodium Hydrogen Phosphate |
| Appearance and State | The anhydrous form is a white crystalline powder; common monohydrate (NaH₂PO₄·H₂O) and dihydrate (NaH₂PO₄·2H₂O) are both colorless crystals. | The anhydrous form is a white powder; the common dodecahydrate (Na₂HPO₄·12H₂O) is colorless monoclinic crystals, which is easily efflorescent. |
| Solubility (20°C) | Approximately 75.5 g/100 g water (freely soluble) | Approximately 7.8 g/100 g water (soluble) |
| pH of Aqueous Solution | 1% solution pH ≈ 4.5 (acidic) | 1% solution pH ≈ 9.0 (weakly alkaline) |
| Melting Point | The anhydrous form melts (decomposes) at about 200°C | The anhydrous form melts (decomposes) at about 243-245°C |
| Hygroscopicity | The anhydrous form is highly hygroscopic and requires airtight storage | The dodecahydrate easily loses crystal water in air |
Health Benefits
pH Regulation
Disodium hydrogen phosphate (DHT) regulates pH. It reacts with acidic substances in food to produce salt and water, neutralizing the acidity and raising the food's pH level. Adding DHT during processing neutralizes acidic substances, raising the pH and resulting in a smoother texture, while also helping to preserve nutrients.
Improved Texture and Color
DHT reacts with acidic substances in food to produce carbon dioxide gas, making the food softer. It also reacts with colored substances in food, improving its color and making it more appealing.
Antioxidant Effect
In some foods, DHT acts as an antioxidant, delaying oxidative spoilage. For example, adding an appropriate amount of DHT to oils can extend their shelf life and maintain freshness and quality.
Application Areas Overview
Stable Market Demand Growth: Due to the widespread application of disodium hydrogen phosphate in food, pharmaceuticals, and other fields, market demand is relatively stable and shows a gradual upward trend. Particularly in the food additive sector, the demand for disodium hydrogen phosphate has increased as people pay more attention to food safety and quality.
Disodium hydrogen phosphate is used as a quality improver in food processing. For example, it acts as an emulsifier and stabilizer in cheese and beverage processing; in the processing of cured meats, sausages, and cooked meat products, it can make the color brighter, improve the taste, and shorten processing time. It also increases the complexation of metal ions, pH value, and ionic strength in food, thereby improving the binding force and water-holding capacity of food.
Pharmaceutical Industry: Disodium hydrogen phosphate is used in the pharmaceutical industry as a drug formulation and buffer, and is widely used in drug production processes. Analysis of the current status of the disodium hydrogen phosphate industry indicates that with the development of medical technology and increased public attention to health, the demand for disodium hydrogen phosphate in the pharmaceutical industry is also gradually increasing.
Core Roles in the Pharmaceutical Field:Buffer Solution Preparation: As a pH adjuster, disodium hydrogen phosphate is used to prepare drug buffer solutions, maintaining solution stability and ensuring drug efficacy. For example, in injection solutions or eye drops, it can reduce tissue irritation.
Phosphorus Supplementation: Clinically used to treat hypophosphatemia, helping patients restore normal phosphorus metabolism.
Industrial Cleaning and Water Treatment: Disodium hydrogen phosphate is an important component of many industrial cleaning agents and metal surface treatment agents. Water Treatment: As a water softener, corrosion inhibitor, and pH adjuster, it is used in industrial circulating cooling water and boiler water treatment to complex calcium and magnesium ions in water, preventing scale formation; it is also used in wastewater treatment to adjust wastewater pH, and in conjunction with flocculants to improve sedimentation. It can also be used for complexation treatment of electroplating wastewater to mask heavy metal ions.
Electroplating and Surface Treatment: As a buffer and complexing agent in electroplating solutions, it stabilizes the pH value of the plating solution, improves the uniformity of the coating, and reduces pinholes and burrs. It is mainly used in electroplating processes such as zinc, nickel, and chromium plating, and also in phosphating treatment of metal surfaces to enhance coating adhesion.
Textile Printing and Dyeing: As a water softener, color fixative, and pH adjuster, it softens the water used in pretreatment for printing and dyeing, preventing hard water ions from affecting dye dissolution and dyeing effects. During the dyeing process, it stabilizes the pH of the dye bath, improving dye uptake and color fixation, and is especially suitable for printing and dyeing cotton, linen, and synthetic fiber fabrics.
