Sodium Lactate
Formula:
CH₃CH(OH)COONa (C₃H₅O₃Na)
GOST/CAS:
CAS 72-17-3 / 867-56-1 (L-форма)
Sodium Lactate (the sodium salt of lactic acid) is a highly effective humectant, antioxidant synergest, and natural bacteriostatic preservative. The product is a clear, viscous, syrupy liquid, ranging from colorless to light yellow, featuring a faint characteristic odor and a mildly saline taste. Due to its exceptional capacity to retain moisture even under low temperatures and low relative humidity, sodium lactate is an indispensable component in both the food industry and cosmetic manufacturing, ensuring structural stability and significantly extending shelf life.
Applications
Food Industry (Meat, Poultry, & Convenience Foods): Used to extend shelf life by lowering water activity and inhibiting the growth of pathogenic bacteria, including Listeria monocytogenes. It effectively retains juiciness and stabilizes the color of processed meat products.
Bakery and Confectionery: Improves dough structure and porosity, prevents staling and drying out, and imparts a pleasant, mild flavor profile.
Cosmetic Industry: Functions as a powerful hydrating agent and is a natural component of the skin's Natural Moisturizing Factor (NMF). It serves as a safe, bio-based alternative to propylene glycol and glycerin in creams, lotions, toners, and shampoos.
Pharmaceuticals & Medicine: Incorporated into complex intravenous infusion solutions to correct fluid-electrolyte balance and manage metabolic acidosis.
Key Advantages
Superior Moisture Retention: Demonstrates excellent hygroscopic properties that function reliably under extreme low-humidity and low-temperature conditions, protecting food matrixes and cosmetic formulations from drying out.
Extended Shelf Life: Provides a pronounced bacteriostatic effect that delays the development of spoilage microflora, allowing manufacturers to reduce the dosage of harsh synthetic preservatives.
Enhanced Sensory Profile: Acts as a synergest with antioxidants to lock in the finished product's natural color while smoothly balancing and enhancing flavor notes.
Safe and Eco-Friendly: Fully biodegradable and non-toxic. Approved for use by leading global regulatory authorities (including FDA status as a GRAS substance).
