Product Name:Sodium lactate
English Name:Sodium lactate
CAS No.:72-17-3
Aliases:L-Sodium lactate, Sodium 2-hydroxypropanoate, Lactic acid sodium salt
Molecular Formula:C3H5NaO3
Physical Properties:Molecular weight: 112.06. Colorless or slightly yellow transparent syrupy liquid, odorless or with a slight characteristic odor, with a slightly salty and bitter taste. Freely soluble in water, ethanol, and glycerol; the aqueous solution is neutral or slightly alkaline. Relative density: 1.38–1.42 (20°C). Melting point: approximately 17°C. Decomposes when heated above 113°C.
Uses:Sodium lactate is used as a humectant, emulsifier, and pH regulator in cosmetics and personal care products. It serves as a buffering agent, flavor enhancer, and preservative in the food industry. In the pharmaceutical field, it is used as an electrolyte supplement and pharmaceutical excipient. It is also used as a raw material for the synthesis of biodegradable polylactic acid.
Technical Specifications:
Assay (as C3H5NaO3) ≥80%
pH of 20% aqueous solution: 6.0–8.0
Heavy metals (as Pb) ≤10 mg/kg
Arsenic (As) ≤2 mg/kg
Chloride (as Cl) ≤0.05%
