Lactic Acid

Lactic acid is a naturally occurring organic acid widely used in food processing, pharmaceuticals, cosmetics, and industrial manufacturing. Known for its mild acidity, biodegradability, and safety, lactic acid is a key ingredient in food preservation, flavor enhancement, and beverage production, where it acts as a natural preservative and pH regulator. In cosmetics and personal care, it is valued for its exfoliating and moisturizing properties, making it a popular choice in skincare formulations, soaps, and shampoos.

Beyond consumer applications, lactic acid functions as a reagent, pH adjuster, and intermediate in diverse chemical processes. It plays a central role in biodegradable polymer production (such as polylactic acid or PLA), textile treatments, leather tanning, and specialty coatings. Its versatility also extends to agrochemicals, cleaning products, and pharmaceutical synthesis, where reliability and safety are critical. With its renewable origin and broad application range, lactic acid remains an essential raw material across industries seeking sustainable, high-performance solutions.
