DL-Lactic acid solution is widely used in the food and beverage industry as an acidulant and preservative. It helps control pH, enhances flavor, and inhibits microbial growth, making it valuable in dairy products, beverages, and baked goods. In the pharmaceutical sector, it serves as an excipient in drug formulations and plays a role in topical treatments due to its mild antimicrobial and keratolytic properties. The solution is also employed in the cosmetic industry for skin care products, where it acts as a moisturizer and exfoliant, promoting smoother skin by aiding in the removal of dead skin cells. In industrial applications, DL-lactic acid solution is used in leather tanning, textile processing, and as a biodegradable cleaning agent. Its ability to chelate metal ions makes it useful in water treatment and detergents. Additionally, it serves as a precursor in the production of biodegradable polymers like polylactic acid (PLA), used in packaging and bioplastics.
