What Is Sodium Lactate?
Sodium lactate is a compound derived from natural lactic acid, commonly obtained through the fermentation of carbohydrates. It, the sodium derivative of lactic acid, is extensively utilized in various sectors such as food, pharmaceuticals, and personal care.
Renowned for its multifaceted properties, sodium lactate acts as a humectant, drawing moisture to the skin and a moisturizer, enhancing skin hydration. Additionally, it serves as a pH regulator in various formulations, a preservative in food products, and a flavor enhancer, particularly in cured meats and cheeses. Its versatility and effectiveness make it a valuable ingredient in numerous applications.
Sodium Lactate VS Lactic Acid
These are two different compounds. There are some differences between them in terms of chemical structure and application.
Sodium lactate is an inorganic salt, the sodium salt form of lactic acid. It can be a colorless or slightly yellow transparent syrupy liquid. But at room temperature, it appears as a white powder. It has a strong ability to absorb water. It is odorless or has a slightly special smell. This compound has a slightly salty and bitter taste. It is miscible in water, ethanol, and glycerol.
Sodium lactate powder is widely used in the food field as an emulsifier, humectant, flavor improver, etc. Its E number is E320. It is also used as a component for replenishing body fluids or electrolytes in the medical field.
Lactic acid, with the chemical name 2-hydroxypropionic acid, is an organic acid. It is an important metabolite in the glycolysis pathway. Lactic acid is produced in the body through glycolysis and plays a role in various biological processes. It plays an important role in the tumor microenvironment. For example, it acts as a metabolic checkpoint to control immune responses and affects the efficiency of PD-1 blockade. Moreover, lactic acid plays a key role in tumor cells’ metabolism, signal transduction, and immunosuppression.
Sodium lactate and lactic acid also differ in their uses. The former ingredient is commonly used as a food additive for medical purposes and personal care products. On the other hand, lactic acid is more related to organisms’ metabolic processes and is used in clinical monitoring to assess tissue perfusion and oxygenation status.
In summary, sodium lactate is the sodium salt form of lactic acid and is usually used as an additive. Lactic acid itself is a metabolite in organisms and is related to various physiological and pathological processes.
Sodium Lactate VS Sodium Chloride
These two names are very similar, but they are two completely different compounds.
Sodium chloride is an inorganic salt. The chemical formula is NaCl. It is commonly called table salt. It is a white crystalline solid. It has a salty taste and is easily soluble in water. Therefore, it is widely used as a flavoring agent in the food industry.
Meanwhile, sodium chloride is the main component of normal saline in the medical field. It is used to treat dehydration, electrolyte imbalance, and other conditions. In this field, sodium lactate replenishes body fluids or electrolytes. It is widely used in continuous mobile peritoneal dialysis (CAPD) for kidney patients and as dialysis fluid on ordinary artificial kidneys.
- Physiological effects
Sodium lactate produces sodium bicarbonate after metabolism in the body. It helps correct metabolic acidosis.
Sodium chloride is necessary to maintain extracellular fluid osmotic pressure and neuromuscular function, but excessive intake may cause health problems such as hypertension.
- Safety
Toxicity of sodium lactate. ADI value is not restricted (FAO/WHO, 2001). It is not suitable for infants with lactose intolerance.
Sodium chloride is generally considered safe. However, it needs to be consumed in moderation, as excessive intake may cause health problems.
In summary, although both are sodium salts, there are obvious differences in their chemical properties, uses, and physiological effects. Sodium chloride is a common condiment and electrolyte supplement. The other has specific applications in the food and medical fields.
Sodium Lactate VS Hyaluronic Acid
Their chemical structure, sources, and applications differ in skin care products.
Sodium lactate is produced by the reaction of Lactic Acid with Sodium Hydroxide. It is used as a food additive, pH adjuster, humectant, etc. In the food industry, it is used as a preservative because it can help control the pH value, thereby inhibiting the growth of microorganisms.
Sodium hyaluronate is the sodium salt form of Hyaluronic Acid, shortly called HA. It is a polysaccharide that occurs naturally in human skin, synovial fluid, and other tissues. Hyaluronic acid HA is a high molecular weight polysaccharide. It is known for its strong moisturizing ability. It can absorb and retain a large amount of water. In skin care products, sodium hyaluronate is used for moisturizing, anti-wrinkle, and providing skin elasticity.
The main differences between the two include:
- Molecular size and solubility
Sodium hyaluronate has a larger molecular weight. It mainly acts on the skin’s surface, helping retain moisture and prevent water loss. Sodium lactate, on the other hand, has a smaller molecular weight and is water-soluble. It can penetrate deeper into the skin layer and provide deep moisturizing.
- Stability
Sodium hyaluronate is more susceptible to oxidation. Sodium lactate is more stable. Therefore, the latter is more popular in cosmetic formulations.
- Aplikacije
Sodium hyaluronate is widely used in skincare products, especially those that provide deep moisturizing and anti-aging effects. The other compound can be used in many fields, such as the food industry, skin care products, etc.
When developing skin care products, one of the two compounds can be added according to the functionalities the product mainly targets, such as skin type, specific needs, etc. In short, both can provide moisturizing effects to the skin. However, their working principles and application ranges are different.
