Quality Control

Our Benzoylperoxide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product is tested against rigorous in-house specifications, which may align with relevant pharmacopeial standards (e.g., USP, BP, EP) for applicable grades. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Keep away from incompatible materials such as strong acids, bases, reducing agents, and accelerators. Due to its nature as a strong oxidizer, store separately from combustible and organic materials. Recommended storage temperature: 15-25°C.
