Description

L-Lactic Acid, 40% Solution is the high-purity, biologically-derived isomer of lactic acid, a fundamental organic acid widely used as a versatile chemical intermediate and pH regulator. This aqueous solution offers a convenient and safe handling form for industrial processes requiring precise acidity and chiral specificity. It is essential for manufacturers in the food, pharmaceutical, cosmetic, and biodegradable polymer industries seeking a reliable, high-quality organic acid source.

Application

• Food & Beverage Industry: As an acidulant, flavor enhancer, and pH control agent in beverages, dressings, and confectionery.
• Pharmaceutical Synthesis: As a chiral building block for active pharmaceutical ingredients (APIs) and in topical formulations.
• Biodegradable Polymers (PLA): As a key monomer in the production of polylactic acid (PLA), a sustainable bioplastic.
• Personal Care & Cosmetics: As an active ingredient in skin care products for its moisturizing and gentle exfoliating (AHA) properties.
• Industrial Cleaning & Descaling: As an effective, biodegradable component in eco-friendly cleaning formulations.
• Chemical Synthesis: As an intermediate in organic synthesis for esters, lactates, and other derivatives.
• Animal Feed & Agriculture: As a feed preservative and acidifier to promote gut health in livestock.
