What is Lactic Acid (CAS 50-21-5)?
Lactic Acid (CAS 50-21-5) is an organic acid that is naturally found in fermented products such as yogurt, sauerkraut, and in the human body. It is a colorless to slightly yellow liquid with a strong acidic taste and is produced via fermentation of sugars. Lactic acid plays a crucial role in the food, pharmaceutical, cosmetic, and chemical industries due to its versatile properties.
Lactic acid exists in two stereoisomeric forms: L-lactic acid (naturally occurring) and D-lactic acid (produced by bacteria). This acid is highly soluble in water and ethanol, making it useful in various aqueous solutions and formulations.
