Sodium lactate is a compound with the CAS number 72 - 17 - 3. Chemically, it is the sodium salt of lactic acid. It is usually presented as a colorless to yellowish, syrupy liquid. The molecular formula of sodium lactate is C₃H₅NaO₃, and its molecular weight is approximately 112.06 g/mol. It is highly soluble in water, which makes it easy to incorporate into various formulations.
In terms of purity, the product we supply can reach a high - level standard, meeting the requirements of different industrial applications. It has a relatively stable chemical property under normal storage conditions (room temperature and dry environment), but it should be kept away from strong oxidizing agents to prevent chemical reactions.
2.1 Food Industry
Sodium lactate is widely used in the food industry as a preservative, flavor enhancer, and pH regulator. It can extend the shelf life of meat products by inhibiting the growth of bacteria. In addition, it can improve the flavor and texture of food products, making them more palatable.
2.2 Cosmetics Industry
In cosmetics, it serves as a humectant and moisturizer. It can help the skin retain moisture, making the skin feel soft and smooth. It is also used in hair care products to improve the manageability and shine of hair.
2.3 Pharmaceutical Industry
It is used in pharmaceutical formulations as a buffering agent. It can maintain the stability of the pH value of drugs, ensuring the effectiveness and safety of drugs.
3.1 Food Applications
When using sodium lactate in food, it should be added in an appropriate proportion according to the type of food and relevant food safety standards. Usually, it can be directly added to the food during the production process and mixed well. The dosage is generally in the range of 0.1% - 2%, but this may vary depending on specific product requirements.
3.2 Cosmetics Applications
In cosmetics, it can be added to the water - based phase of formulations. The addition should be carried out under aseptic conditions to prevent contamination. The typical concentration is between 2% - 10%, depending on the specific product type, such as creams, lotions, or serums.
3.3 Pharmaceutical Applications
In the pharmaceutical field, it is added during the drug - manufacturing process. The dosage and addition method should be strictly in accordance with the drug formula and manufacturing process requirements, usually under the supervision of professional pharmaceutical technicians.
4.1 Case in Meat Products
A meat processing factory used our sodium lactate in its sausage production. By adding 0.5% sodium lactate to the sausage formula, the shelf life of the sausages was extended from 10 days to 20 days at room temperature. Moreover, the flavor of the sausages was improved, and the texture became more tender and juicy, which increased customer satisfaction and sales.
4.2 Case in Skin Care Products
A cosmetics company incorporated 5% sodium lactate into its moisturizing lotion. After a user trial with 100 volunteers for one month, 80% of the volunteers reported that their skin felt more hydrated and smoother. The lotion also received positive feedback on the market, leading to an increase in sales volume.
4.3 Case in Oral Drugs
A pharmaceutical company used sodium lactate as a buffering agent in an oral tablet formulation. By precisely controlling the amount of sodium lactate, the stability of the drug's pH value was maintained during the storage period. This ensured that the drug's efficacy remained unchanged, reducing the risk of drug degradation and improving the quality of the drug.
