Sodium Lactate is a common ingredient used in cosmetics and personal care products. It is the sodium salt of lactic acid, a natural acid derived from the fermentation of sugars. Sodium Lactate is typically a clear, colorless liquid with a mild odor and serves multiple functions in skincare products. It acts as a humectant, attracting and retaining moisture in the skin, promoting hydration and preventing dryness. Additionally, Sodium Lactate can function as a pH regulator, helping to stabilize and adjust the pH of formulations. The chemical formula of Sodium Lactate is NaC₃H₅O₃.

Sodium lactate is a common ingredient in cosmetics and skincare products. It's a natural component of the skin's Natural Moisturizing Factor (NMF) and can serve multiple functions in skincare products, including: 

• Humectant: Attracts and binds to water from the atmosphere and deeper layers of the skin, improving the skin's moisture content by up to 84%. This helps keep skin hydrated and prevents dryness. 
• Keratolytic agent: Helps remove dead skin cells from the skin's surface. 
• Buffering agent: Controls the pH of cosmetic products. 
• Exfoliant: Can be used as an exfoliant, but the salt aspect of sodium lactate makes it weaker for this purpose than lactic acid. 

Sodium lactate is also known as lactic acid, sodium salt. It's a colorless or yellowish syrupy liquid with a mild odor. It's considered very hygroscopic, meaning it absorbs moisture from its environment and improves water retention. The US FDA classifies sodium lactate as a food additive emulsifier, which further signifies its safety for cosmetic use. 

Sodium lactate is found in many skincare products, including body wash, cleanser, body lotion, shampoo, and conditioner.
