What is Sodium Lactate CAS 72-17-3?

Sodium Lactate is the sodium salt of lactic acid, also called sodium 2-hydroxypropanoate. It is commonly supplied as an approximately 60% aqueous solution and is used for moisture retention, pH buffering and preservation support in food, cosmetic and pharmaceutical applications.

What is the molecular formula of Sodium Lactate?

The molecular formula of the sodium salt is C₃H₅NaO₃, with a molecular weight of about 112.06 g/mol. The commercial liquid product is a solution of this salt, so the concentration should be specified when ordering.

What are the main uses of Sodium Lactate?

It is used in meat and poultry processing, beverages, dairy products, sauces and dressings for preservation support and moisture retention. In personal care it acts as a humectant, moisturizer and pH buffer in products such as lotions, cleansers and hair care.

Why is Sodium Lactate often supplied as a 60% solution?

The 60% aqueous solution is a practical, stable commercial form for food and cosmetic manufacturing. It is water-miscible and easy to dose, but buyers should confirm the target concentration, pH and purity for their formulation.

Is Sodium Lactate suitable for food and cosmetic use?

Food-grade sodium lactate is widely used and is listed as E325 in the EU. Cosmetic and food grades should be selected for their intended market, with the L-isomer commonly preferred for food and personal-care applications.

How should Sodium Lactate be stored and handled?

Store it in tightly closed containers in a cool, dry, well-ventilated area away from strong oxidizers. Use appropriate liquid-chemical handling controls and PPE when transferring or dosing the material.

Product Description

Sodium Lactate, CAS 72-17-3, also known as sodium 2-hydroxypropanoate or E325, is the sodium salt of lactic acid; the EC/EINECS number is 200-772-0.

Synonyms: sodium 2-hydroxypropionate; lactic acid sodium salt; E325; sodium L-lactate; 2-hydroxypropanoic acid sodium salt.

CAS: 72-17-3.

Molecular formula: C₃H₅NaO₃.

Molecular weight: 112.06.

EC number: 200-772-0.

It is commonly supplied as a clear, colorless to slightly yellow aqueous solution (typically about 60% sodium lactate), with a pH of about 6.5–8.5 at 20 °C.

The density is about 1.30–1.35 g/cm³ at 20 °C, and it is completely miscible with water.

It has a slight characteristic odor; the anhydrous sodium salt is also available as a powder or concentrated form if required.

It is used in meat, poultry and seafood processing for preservation support and moisture retention to improve juiciness and yield.

It is used in beverages, dairy products, sauces and dressings as a mild pH buffer, and in bakery products for texture and water retention.

It is used in personal care as a humectant, moisturizer and pH buffer in lotions, cleansers and hair care; food-grade sodium lactate is listed as E325.

Confirm assay, concentration, pH, density, lactic acid content, sodium content, heavy metals and microbial limits; select food, cosmetic or pharma-intermediate grade.

Store in tightly closed containers in a cool, dry, well-ventilated area away from strong oxidizers; use liquid-chemical handling controls and suitable PPE.
