Description

Lactic Acid CAS NO 50-21-5 is a versatile organic acid and a key biochemical building block. It is essential for a wide range of industrial processes due to its natural origin, biodegradability, and multifunctional properties. This product is critical for manufacturers in the food & beverage, pharmaceutical, cosmetic, and biodegradable polymer industries seeking sustainable and effective acidulants, pH adjusters, and chemical intermediates.

Application

• Food & Beverage Industry: Primary use as an acidulant, flavor enhancer, and pH regulator in dairy products, beverages, dressings, and confectionery.
• Pharmaceutical & Personal Care: Key ingredient in topical formulations, moisturizers, and anti-aging products; also used as a pH adjuster in drug synthesis and as a chiral intermediate.
• Biodegradable Polymers (PLA): The monomer for producing polylactic acid (PLA), a sustainable bioplastic used in packaging, textiles, and medical devices.
• Industrial Applications: Used in metal cleaning, electroplating baths, textile dyeing, and as a descaling agent.
• Animal Feed & Agriculture: Employed as a preservative and acidifier in silage and feed to inhibit microbial growth.
• Chemical Synthesis: Serves as a green solvent and a precursor for lactate esters, propylene glycol, and acrylic acid.

Quality Control

Our Lactic Acid is produced and tested under a rigorous quality management system. We offer grades compliant with major international standards including FCC (Food Chemicals Codex), USP (United States Pharmacopeia), and Kosher certification where applicable. Every batch is supported by a comprehensive Certificate of Analysis (COA) to ensure it meets precise specifications for identity, purity, and safety.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. As a strong acid/organic solvent, ensure containers are kept upright and sealed to prevent moisture absorption and contamination.
