Lactic Acid, known by its CAS number 50-21-5, is a fundamental organic acid with a chemical structure that lends itself to a multitude of applications. Its presence in nature, particularly in fermented foods and within the human body, underscores its significance. This article by NINGBO INNO PHARMCHEM CO.,LTD. aims to provide a clear understanding of lactic acid's core properties, common production methods, and critical safety aspects.

At its core, lactic acid is a carboxylic acid characterized by a hydroxyl group on the alpha-carbon atom. This structure grants it unique chemical behaviors, including its acidic nature and its ability to form esters. Commercially, it is often available as an 80-85% aqueous solution, appearing as a colorless to pale yellow, syrupy liquid. Its solubility in water and alcohol makes it easy to incorporate into various formulations. Exploring the lactic acid chemical properties is key to appreciating its broad utility.

The production of lactic acid primarily follows two routes: chemical synthesis and biological fermentation. While chemical synthesis exists, biological fermentation, often using bacteria like *Lactobacillus*, is the predominant method globally. This biological route is favored for its ability to produce specific isomers and its use of renewable feedstocks, aligning with sustainability goals. The efficiency and cost-effectiveness of these lactic acid production methods ensure its widespread availability.

When it comes to safety, lactic acid is generally considered safe when used appropriately in diluted forms, as is common in food and cosmetic applications. However, concentrated solutions can be corrosive to skin and eyes, necessitating proper handling procedures and the use of personal protective equipment. Understanding the lactic acid safety and toxicity profile is crucial for anyone working with the chemical.
