Product Information

Sodium Lactate CAS:312-85-6 is the sodium salt of lactic acid (2-hydroxypropanoic acid), with the chemical formula C₃H₅NaO₃. It is an organic acid salt produced by the neutralization reaction of natural lactic acid with sodium hydroxide. Its molecular structure contains hydroxyl (-OH) and carboxylate (-COONa) groups, giving it excellent water solubility, strong moisturizing properties, good pH regulating ability, and excellent biocompatibility. Furthermore, it is derived from natural sources (it can be prepared by fermentation of biomass such as corn and sugarcane), making it a widely used multifunctional additive in the food, pharmaceutical, cosmetic, and industrial sectors, and particularly important in natural and green product systems.

Uses and Applications

With its core advantages of "natural origin, excellent moisturizing properties, pH regulation, biocompatibility, and low toxicity," sodium lactate has widely penetrated the three core fields of food, medicine, and daily chemicals. It also has important applications in niche areas such as industrial antifreeze and metal processing, making it one of the fastest-growing natural additives globally.

1. Food Industry: Natural Moisturizing, Preservative, and Quality Improvement Agent

As a naturally derived food additive permitted for use in China (GB 2760-2014), sodium lactate can simultaneously provide moisturizing, preservation, flavoring, and pH adjustment functions. It is odorless and does not affect the original flavor of food, making it an ideal additive for meat products, dairy products, baked goods, and other food products.

2. Personal Care Sector: Key Natural Ingredients for Moisturizing and Skin Conditioning

Sodium lactate is a naturally occurring component in human skin (the stratum corneum contains 0.5% to 1.0% lactate), exhibiting excellent compatibility with the skin. Its moisturizing performance is superior to traditional humectants such as glycerin and propylene glycol, making it a high-end natural ingredient for personal care products such as skincare, hair care, and cosmetics.

3. Pharmaceutical field: Fluid replacement and pharmaceutical excipients

Sodium lactate meets pharmacopoeia standards (CP 2020, USP 45, EP 10), is low in toxicity, and has good biocompatibility. It can be used as a fluid replacement agent in clinical treatment and is also an important excipient in pharmaceutical preparations, ensuring drug stability and safety.

4. Industrial Applications: Environmentally Friendly Antifreeze and Corrosion Inhibitors

Sodium lactate possesses excellent antifreeze and corrosion inhibition properties, is biodegradable (BOD₅/COD > 0.8), and is environmentally friendly. It is an ideal environmentally friendly alternative to traditional toxic antifreeze agents (such as ethylene glycol and propylene glycol) and corrosion inhibitors (such as chromates and phosphates).
