Lactic Acid in Soap Making

Benefits of Using Sodium Lactate in Soap and Bath Products

Using lactic acid in soap and bath products has numerous benefits. Liquid lactic acid is a natural exfoliant and helps to remove dead skin cells from the surface of the skin. Sodium lactate in soap also helps to balance the pH of the skin, leaving it feeling soft and smooth. It can help to reduce dryness and irritation, making it great for those with sensitive skin.

How Sodium Lactate Contributes to Different Manufacturing Processes

• Sodium Lactate in Cold Process (CP) Soap

In cold process soap making, sodium lactate is added to lye water to harden the soap faster, allowing for quicker unmolding and reduced curing time. It also helps create a smoother, glossier soap bar with fewer imperfections.

• Sodium Lactate in Hot Process Soap

In hot process soap making, sodium lactate is added post-cooking but before molding to speed up hardening, reduce waiting time before cutting, and enhance the soap’s texture, making it smoother and less crumbly.

• Sodium Lactate in Shampoo

Sodium lactate is also used in the formulation of shampoos. Sodium lactate acts as a humectant, helping to retain moisture in the hair and scalp. This can lead to improved hair hydration, making the hair look healthier and more vibrant.

To sum up, sodium lactate is a valuable ingredient in the manufacturing of soaps and shampoos, offering benefits that improve both the production process and the quality of the final products.

Things to Note for Purchasing Lactic Acid for Production of Soap&Bath Products:

Lactic acid storage conditions are a key factor in ensuring lactic acid quality and stability.

• Ideal temperature: Lactic acid should be stored in a cool, dry environment. The ideal storage temperature is usually between 15°C and 25°C.

• Avoid high temperatures: High temperatures will accelerate the degradation of lactic acid, affecting its quality and effectiveness. Therefore, storing lactic acid in high temperature environments should be avoided.

• Low humidity: Lactic acid is sensitive to humidity. Excessive humidity will cause lactic acid to absorb moisture, affecting its purity and stability. The relative humidity of the storage environment should be kept below 50%.

• Sealed Containers: Store lactic acid in well-sealed containers to prevent it from absorbing moisture and moisture.

• Store away from light: Lactic acid should be stored away from light, especially direct exposure to sunlight. Light will accelerate the degradation of lactic acid and affect its quality.

• Keep away from heat sources: Store lactic acid away from heat sources, such as heaters, stoves, and windows in direct sunlight.

• Keep away from flammable materials: Lactic acid should be kept away from flammable materials and other chemicals to prevent chemical reactions or fires.

• Protective Equipment: When handling lactic acid, wear appropriate protective equipment such as gloves, goggles, and protective clothing to prevent skin and eye contact.
