Description
Benzoic Acid USP 99.5% | Food Preservative E210 Grade
High Purity Benzoic Acid for Food and Pharmaceutical Preservation
Benzoic Acid (CAS No. 65-85-0) is a white crystalline organic acid with a chemical formula C₇H₆O₂. It is widely used in the food, pharmaceutical, cosmetic, and chemical industries. Offered in USP Grade with a purity of 99.5%, it appears as white crystals, scales, or needles and is known for its mild, characteristic odor.
Benzoic Acid is best known as a preservative due to its antifungal and antibacterial properties, particularly effective in acidic environments. It is also a critical intermediate in the synthesis of many organic substances, including benzoyl chloride, phenol, alkyd resins, and plasticizers.
In pharmaceuticals, Benzoic Acid is used in topical preparations to treat skin conditions and in oral formulations as a pH adjuster and preservative when you buy benzoic acid USP grade from certified chemical suppliers. In the cosmetics and personal care industry, it stabilizes formulations and extends shelf life.
Food Preservation and Safety Applications of USP Benzoic Acid
This product complies with USP quality standards, making it suitable for regulated applications. It should be handled with care, stored in a cool, dry, and well-ventilated area, away from strong oxidizing agents and moisture.
For food preservation applications, benzoic acid serves as the primary antimicrobial agent in food grade chemical formulations where microbial control is essential. The Food and Agriculture Organization provides comprehensive guidelines for benzoic acid usage in food preservation systems.
Storage and Handling Requirements
The compound requires proper storage in sealed containers within controlled environments to maintain its antimicrobial efficacy. Professional handling ensures optimal performance for industrial and laboratory chemical applications across various manufacturing processes.
