لاکتیک اسید 85%

Lactic Acid 85% is a naturally occurring organic acid with the chemical formula C₃H₆O₃. It is widely used in pharmaceutical and laboratory applications due to its versatile properties.

🏭⚗️ Production
Lactic acid is primarily produced through the fermentation of carbohydrates by lactic acid bacteria. The 85% concentration is achieved through distillation and purification processes to remove water and other impurities, resulting in a high-purity liquid suitable for various applications.

🔬 Properties
Lactic acid 85% is a colorless to pale yellow liquid with a characteristic odor. It has a molecular weight of 90.08 g/mol and a density of approximately 1.2 g/mL at 20°C. The pH of a 5% aqueous solution is typically between 2.2 and 2.6. It is soluble in water and ethanol and exhibits hygroscopic properties.

🧪 Applications
In pharmaceutical formulations, lactic acid 85% is used as a pH adjuster in injectable solutions, topical preparations, and oral medications. It serves as a preservative and antimicrobial agent in various formulations. In laboratory settings, it is employed in biochemical assays, as a reagent in chemical synthesis, and in the preparation of buffers. Additionally, lactic acid is utilized in the production of biodegradable polymers, such as polylactic acid (PLA), for medical and industrial applications.

⚠️ Safety
Lactic acid 85% is classified as a corrosive substance and should be handled with appropriate safety precautions. It can cause severe skin and eye irritation upon contact and may be harmful if swallowed or inhaled. Personal protective equipment, including gloves, goggles, and lab coats, should be worn when handling this substance. It should be stored in tightly sealed containers in a cool, dry, and well-ventilated area, away from incompatible materials.
