Sodium Lactate (CAS 72-17-3 / 312-85-6) is a natural sodium salt of lactic acid. It appears as a colorless or slightly yellowish transparent syrupy liquid, readily soluble in water, with excellent moisturizing properties, pH regulation ability and broad-spectrum antibacterial activity.
As a generally recognized as safe (GRAS) food additive and multifunctional raw material, sodium lactate is widely used in food processing (antiseptic and fresh-keeping for meat products), pharmaceutical preparations (correction of acidosis) and personal care products (natural moisturizing factor).
As a source manufacturer, we provide food-grade, pharmaceutical-grade and other multi-specification products, supporting stable bulk supply.

Key Application
1. Food Industry: Efficient Natural Preservative & Preservative Agent
Preservation for Meat & Poultry Products:
Effectively inhibits pathogenic bacteria such as Listeria monocytogenes and Escherichia coli, extends the shelf life of meat products by 30%–100%, and enhances product flavor.
Emulsification & Moisture Retention:
Acts as an emulsifier and humectant to improve food texture and reduce water loss.
Sodium Chloride Replacement:
Serves as part of salt-reduction solutions, safer for people with hypertension and kidney disease.
2. Pharmaceutical Field: Acidosis Corrector & Dialysis Buffer
Metabolic Acidosis Treatment:
Used as an ingredient in intravenous injections, metabolized into sodium bicarbonate in the body to correct acidosis.
Peritoneal Dialysis Solutions:
Applied as a buffer in Continuous Ambulatory Peritoneal Dialysis (CAPD) solutions and artificial kidney dialysate.
Hyperkalemia Treatment:
Helps potassium ions enter cells and relieves cardiac arrhythmia.
3. Personal Care & Cosmetics: Natural Moisturizing Factor
Skin Care Products:
Sodium lactate is a key component of the Natural Moisturizing Factor (NMF) in the skin’s stratum corneum, accounting for 25% of stratum corneum moisturizing ingredients, effectively preventing skin moisture loss.
Hair Care Products:
Acts as a mild pH adjuster to improve hair texture and enhance combability.
Oral Care:
Used as an anti-tartar agent, synergistic with other calcium sources.
4. Other Industrial Applications
Plasticizer & Antifreeze Agent:
Used in casein plastics and alcohol antifreeze for corrosion protection.
Glycerin Substitute:
Replaces glycerin in specific industrial formulations.
