Citric Acid 25% Solution

Product Overview

Citric Acid 25% Solution is a clear, colorless liquid that presents as a stable aqueous solution with citric acid (C₆H₈O₇) as the primary active component. On a typical basis, it contains 25% w/w citric acid, dissolved in water, and is formulated to deliver reliable acidulant and pH adjustment performance across diverse process streams. The solution exhibits a slightly sour odor and demonstrates high solubility in water, allowing straightforward integration into food, pharmaceutical, cosmetic, and industrial cleaning formulations while maintaining consistent concentration control as verified by titration methods aligned with standard pharmacopeial practices. The product is suitable for applications requiring controlled acidity, chelation of trace metals, and compatibility with common processing equipment made from HDPE or glass, under standard manufacturing and housekeeping conditions.

In addition to its primary acidulant role, the Citric Acid 25% Solution supports product stability and formulation integrity through its well-defined assay, low trace metal content, and broad data-specified tolerances. The solution is manufactured under strict quality control to meet USP-NF monograph and food-grade specifications, ensuring traceability, lot-to-lot consistency, and compliance with applicable industry standards. This combination of chemical purity and robust performance makes the product a reliable choice for both R&D and production environments where precise acidification, buffering, and metal-chelation behavior are required.

Safety Precautions

Handling and storage should be performed in a well-ventilated area, away from direct sunlight and incompatible materials. Use compatible containers (HDPE or glass) and avoid contact with strong oxidizers. Personal protective equipment (PPE) including gloves, goggles, and appropriate lab apparel is recommended to minimize exposure during dispensing and transfer. Store in a cool, dry place, kept tightly closed when not in use, to preserve assay accuracy and minimize moisture uptake.

For exposure scenarios and emergency procedures, consult the SDS. In case of eye contact, rinse cautiously with water for several minutes and remove contact lenses if present. If irritation persists, seek medical advice. For skin exposure, wash with soap and water; if irritation occurs, obtain medical guidance. If inhaled, move to fresh air and seek medical attention if symptoms persist. If swallowed, rinse mouth and do not induce vomiting; seek medical attention if unwell. Product shipments are labelled with UN 1760 and appropriate hazard classifications.
