Acetic Acid 18% is an aqueous solution of acetic acid with a concentration of 18%, designed for laboratory and pharmaceutical applications where controlled acidity is required.
🏭⚗️ Production
Acetic Acid 18% is prepared by diluting glacial acetic acid with distilled or deionized water under controlled conditions. The solution is stored in tightly sealed containers to prevent contamination and maintain its concentration and stability over time.
🔬 Properties
The solution is a clear, colorless liquid with a characteristic pungent odor. It is highly soluble in water and exhibits acidic properties, with a stable pH under normal storage conditions. The solution should be protected from extreme temperatures and direct sunlight to prevent concentration changes.
🧪 Applications
In laboratory settings, Acetic Acid 18% is used for buffer preparation, titration, pH adjustment, and various analytical procedures. In pharmaceutical applications, it is employed in the production of formulations, as a preservative, and in processes requiring controlled acidic conditions, ensuring stability and efficacy of the final product.
⚠️ Safety
Acetic Acid 18% is corrosive and should be handled with care. Contact with skin, eyes, or mucous membranes should be avoided, and affected areas should be rinsed immediately with plenty of water. Appropriate protective equipment, including gloves, goggles, and lab coats, must be used. Store in tightly sealed containers in a cool, dry place, away from heat and sunlight. Disposal must follow laboratory safety protocols and local environmental regulations.
