What is Sodium Citrate Dihydrate?

Sodium Citrate Dihydrate, also known as citric acid trisodium salt dihydrate, has the chemical formula Na3C6H5O7·2H2O. It is a white crystalline powdery compound with an odorless, refreshing and salty taste. It is the hydrated form of the sodium salt of citrate produced by the reaction of citric acid with sodium hydroxide or sodium bicarbonate and contains two molecules of crystal water.

Sodium citrate dihydrate is relatively stable at room temperature. It begins to lose crystal water when heated to about 150°C, and is completely dehydrated at 300°C. It has high solubility in water, and the pH value of 5% aqueous solution is close to neutral, about 7.6 to 8.6. Therefore, it is often used as an acid-base buffer to adjust the acid-base balance of the solution.

Sodium Citrate Dihydrate Uses

Food industry
Acidity regulator: Because it can dissociate citrate ions, it can effectively adjust the pH value in the food system, maintain the acid-base balance of the food, and maintain the taste and color stability of the food.
Preservatives: Used as food antioxidants and preservatives, they can delay the deterioration process of food and increase the shelf life.
Emulsifiers and Stabilizers: In dairy products and beverages, sodium citrate helps improve emulsion stability, increase foaming and consistency, and prevent fat separation.
Chelating agent: Forms a stable complex with metal ions to reduce the toxicity of heavy metal ions in food. It can also prevent oxidative browning caused by iron, copper and other elements in food.

Pharmaceutical industry
Anticoagulant: In medical laboratories, sodium citrate dihydrate is used to prepare anticoagulant solutions, such as ACD (citrate-phosphate-dextrose) solution, to prevent blood clotting during blood sample collection. , to ensure the accuracy of blood sample analysis.
Pharmaceutical preparation ingredients: As excipients, it may appear in tablets, injections, or other pharmaceutical preparations to provide buffering or help dissolve the drug.
Medical equipment disinfectant: Under certain conditions, sodium citrate can be used as a cleaning and disinfection aid for medical equipment.

Daily chemical industry
Oral care products: In toothpastes and other oral cleaning products, sodium citrate serves as a pH adjuster and stabilizing ingredient to help maintain a suitable oral environment.
Personal Care Products: In skin care and cosmetics, it acts as a mild pH balancer and moisturizer with a soothing effect on the skin.

Other apps
Water treatment: Sodium citrate can be used to soften hard water, reduce the concentration of calcium and magnesium ions in the water through chelation, and prevent scale formation.
Industrial Cleaners: Used as part of a cleaner formula to remove stains and deposits from metal surfaces while avoiding corrosion.
Experimental reagents: In chemical and biological laboratories, as a component of buffer solutions, they are used for cell culture, DNA extraction and other experiments that require control of pH reaction conditions.

Advantages of Sodium Citrate Dihydrate

  1. Excellent stability: Sodium citrate dihydrate is stable at room temperature and is not prone to hygroscopicity and deliquescence. It only shows slight deliquescence even in humid air and is not easily efflorescent in hot air, ensuring its storage and transportation convenience as a raw material. .
  2. Strong solubility: easily soluble in water and glycerin, and can be quickly dissolved in a variety of solvents to form a clear and transparent solution, which is easy to prepare and apply.
  3. pH adjustment performance: Sodium citrate is a good acid-base buffer and can effectively maintain the solution within a certain pH range, which is crucial for the manufacturing of products that require a stable acid-base environment, such as food, pharmaceuticals, cosmetics and personal care products. wait.
  4. Chelating properties: Sodium citrate can form stable chelates with metal ions to reduce the impact of metal ions on product quality, such as preventing rust smell in the food industry or reducing scale formation in water treatment.
  5. High safety: As a food additive, sodium citrate is non-toxic and safe for the human body. It is recognized by the World Health Organization and food safety agencies of various countries and is widely used in the food industry as a flavoring agent, buffer and stabilizer.
  6. Versatility: In addition to its wide application in the food industry, sodium citrate dihydrate is also suitable for use in the pharmaceutical field, such as as an anticoagulant, cosolvent or making disinfectant, as well as in daily chemical products as a stabilizer and pH adjustment agent.
  7. Environmentally friendly: Compared with some environmentally harmful chemicals, sodium citrate has good biodegradability and has relatively little impact on the environment.
  8. Cost-effectiveness: Citric acid, the raw material for the production of sodium citrate, has a wide range of sources and can be prepared through fermentation. The production cost is relatively controllable, so it has a high cost performance in many application fields.
