What is sodium lactate

Sodium lactate is a natural sodium salt of lactic acid. Its chemical formula is NaC3H5O3, and its CAS Number is 72-17-3. Its IUPAC name is sodium 2-hydroxypropanoate, and it may also be referred to as either sodium DL-lactate or lactic acid sodium salt. This compound is found naturally in the stratum corneum of human skin. When manufactured, it is most often produced through the fermentation of a source of sugar — for example, beets or corn. The compound is subsequently derived by neutralizing the isolated lactic acid that results from the fermentation process.

Sodium lactate is used as a food additive. It has the E number E325 and is available both as a liquid and as a powder. It acts as an acidity regulator, preservative, and bulking agent.

Industries Where Sodium Lactate Is Widely Used

In the food industry, sodium lactate is prized for its antimicrobial ability, which increases food safety and extends shelf life by preventing the development of fungi, yeast, and pathogenic bacteria. Due to its slightly saline taste, the compound is also used to enhance flavor. It is used in fruits, biscuits, nuts, vegetables, certain sponge cakes, and canned and bottled water.

This ingredient is commonly used as a preservative for poultry products and meat. In addition, its water-binding properties help lock moisture in meat products such as bacon, hot dogs, and sausages. As an acidity regulator, sodium lactate is commonly used to control the pH level of a range of dairy products such as cream, condensed milk, and processed cheese.

Sodium lactate is a moisturizing component that is required for the natural hydration of skin and hair. Due to its conditioning properties, as well as its ability to prevent irritation and increase the efficacy of certain hydroxy acids, sodium lactate is used by health and personal care product manufacturers in many liquid soaps, shampoos, conditioners, detanglers, and cosmetics. It can also be used as a bulking agent to create products with a creamier texture or applied as a skin-lightening agent.

Chemical Property Information for Sodium Lactate

The sodium salt of inactive lactic acid or racemic acid, sodium lactate is colorless, odorless, and transparent. It is commonly available in liquid form but may also be obtained in powder form. It has alkalinizing properties and can replenish electrolytes. During the metabolic process, the compound is converted to bicarbonate. The resulting increased plasma bicarbonate enhances the elimination of lactate and hydrogen ions from the bloodstream, which in turn increases the pH level of the blood.
