لاکتیک اسید 30%

Lactic Acid 30% is an aqueous solution of lactic acid, a naturally occurring organic acid, widely used in pharmaceutical and laboratory applications for its acidifying, buffering, and preservative properties.

🏭⚗️ Production
Lactic acid is produced either by fermentation of carbohydrates (such as glucose or sucrose) using lactic acid bacteria, or by chemical synthesis from acetaldehyde. The 30% aqueous solution is prepared by dissolving concentrated lactic acid in purified water to achieve a stable and homogenous solution suitable for analytical and pharmaceutical use.

🔬 Properties
Lactic Acid 30% is a clear, colorless to slightly yellow liquid with a mild acidic odor. It is fully miscible with water and alcohol, chemically stable under normal conditions, and maintains its buffering capacity over a wide pH range. The solution exhibits mild antimicrobial activity and can act as a preservative in certain formulations.

🧪 Applications
In pharmaceutical formulations, Lactic Acid 30% is used as a pH regulator, acidifying agent, and preservative in topical solutions, oral preparations, and cosmetics. It helps maintain the stability and efficacy of active ingredients.
In laboratory settings, the solution is used in titrations, buffer preparations, and analytical assays where precise acidification is required. It is also employed in microbiological media and biochemical experiments to control pH and maintain environmental conditions for reactions.

⚠️ Safety
Lactic Acid 30% is generally safe to handle with standard laboratory precautions. It can cause mild skin or eye irritation upon direct contact, so protective gloves and goggles are recommended. The solution should be stored in tightly closed containers, away from strong oxidizers, and in a cool, well-ventilated area to preserve stability.
