1. Sodium lactate
Sodium lactate, CAS 72-17-3, molecular formula C3H5NaO3, molecular weight 112.06 g-mol-1.
Sodium lactate is usually a colorless or almost colorless transparent liquid, which can be dissolved with water, ethanol, and glycerol. It is used in food preservation, moisturizing, aroma enhancement, and pharmaceutical raw materials, and also used as medicine to relieve acidosis due to diarrhea and dehydration, diabetes, nephritis, and other diseases of Corsair. It is also used as a seasoning, plasticizer of casein plastic, antifreeze, moisturizer, substitute of glycerin, and antifreeze agent of alcohol.
2. Applications of sodium lactate
2.1 In food
(1) It can be used as an emulsifier, humectant, flavor improver, quality improver, antioxidant synergist, and pH adjuster in the meat and poultry food processing industry, which can enhance the flavor, and inhibit the growth of pathogenic bacteria in food and prolong the shelf life of products.
(2) Sodium lactate is used as a food preservative, flavoring agent, antifreeze agent, moisturizing agent, etc. It has partially replaced sodium benzoate as a preservative in the food industry abroad. Sodium lactate has incomparable advantages over sodium benzoate, sodium citrate, sodium sorbate, and so on. Especially in meat products, it has the following significant effects: 1) extend the shelf life: 30% to 100%, or even longer; 2) inhibit the growth of pathogenic bacteria in food, such as E. coli HT, Listeria monocytogenes, Clostridium botulinum, etc., thus increasing food safety; 3) enhance and maintain the flavor of the meat; 4) as a salt, it can not only reduce the amount of sodium chloride but also increase the safety of food. 4. As a salt, sodium lactate can not only reduce the amount of sodium chloride but also be safer for low-salt heart patients, hypertensive patients, and kidney patients.
2.2 Medical field
(1) Liquid can relieve dehydration caused by diarrhea and poisoning caused by diabetes and gastritis. Sodium lactate is used to replenish body fluids or electrolytes in parenteral/solution and is widely used in continuous removable peritoneal dialysis solution (CAPD) for patients with kidney disease and as dialysis solution on ordinary artificial kidneys.
(2) Sodium lactate is used as an electrolyte and dialysate in intravenous fluids, as well as in enteral disinfectants, mouthwashes, and bladder injections.
(3) Sodium lactate is also widely used as Ringer’s solution preparation to make injection solutions for the treatment of metabolic acidosis.
(4) Sodium lactate can be very effective in treating skin dysfunction. For example, extreme dryness is caused by dry skin disease. Lactic acid and lactate are used in anti-acne products because of their anti-microbial effects. They are often used in combination with many other active ingredients to produce synergistic effects.
2.3 Daily chemical field
Lactic acid and lactates, natural components of human skin and hair, have unique pH-regulating and moisturizing properties and are used in a wide variety of daily chemical products, such as bath and shower products, skin care products, hair care products, and oral care products.
3. Classification of sodium lactate
Morphologically, it is divided into sodium lactate solution and sodium lactate powder.
Divided into food grade, pharmaceutical grade from usage
Divided into 50%, 60%, 70%, 80%, 90%(chiral) from content
