Product Introduction

Sodium Lactate is an organic acid salt produced by the neutralization of lactic acid with sodium hydroxide or potassium hydroxide. At room temperature, it presents as a colorless to slightly yellowish liquid that is odorless or has a faint characteristic odor. It is hygroscopic and miscible with water, ethanol, and glycerin in any proportion, but insoluble in chloroform and ether. As a versatile platform chemical, its core advantages lie in moisturizing, bacteriostatic activity, pH buffering, and water retention, making it widely applicable across four major sectors: food, pharmaceuticals, daily chemicals, and industry.

Major Application Areas

1. Food Industry
Meat Products

Inhibits pathogenic bacteria, retains moisture to tenderize meat, and extends shelf life. Suitable for ham, sausages, and ready-to-eat meats, with a typical dosage of 2%–4%.

Flour & Baking

Maximum usage in raw wet noodle products is 2.4 g/kg (per GB 2760). It improves gluten strength, retards staling, and maintains moisture.

Beverages & Dairy

Regulates pH and stabilizes flavor. It can replace part of the salt to reduce sodium intake, making it suitable for yogurt, fruit juices, and sauces.

2. Pharmaceutical Industry
Acid-Base Balance Regulation

Used to correct metabolic acidosis, as a buffer in peritoneal dialysis fluids, and in the treatment of hyperkalemia accompanied by arrhythmia.

Electrolyte Replenishment

Found in Ringer's solution and Compound Sodium Lactate and Glucose Injection, used for rehydration in cases of dehydration and electrolyte imbalance.

Other Uses

Serves as an ingredient in intestinal disinfectants, bladder irrigation solutions, and oral care liquids.

3. Cosmetics & Personal Care
Skincare

Acts as a humectant (in creams, lotions, serums), keratolytic agent, and pH adjuster. It is suitable for dry and sensitive skin, helping to improve absorption efficiency.

Hair & Body Care

Used in shower gels, shampoos, and soaps as a moisturizer and pH adjuster; it enhances foam stability and prevents soap cracking.

Oral Care

Functions as an anti-calculus and gum care ingredient, suitable for toothpaste and mouthwashes.

4. Industrial & Other Uses
Detergents

Acts as a builder to soften hard water and reduce scale formation, suitable for laundry detergents and dishwasher detergents.

Electroplating

Used as a component in electrolytes to regulate pH and ion composition, thereby improving plating quality.

Chemical Intermediate

Serves as a buffer and chelating agent in organic synthesis and water treatment to stabilize reaction systems.

Package & Storage

Packaging

200kg/drum

Storage Condition

Stored in a cool dry ventilated place away from fire, heat, light, acids, and food materials.
