Quality Control

Our Allantoin is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. We offer grades compliant with major pharmacopoeial standards, including USP and EP, as well as cosmetic-grade material. Every batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles, available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect quality and flow properties.
