Quality Control

Our production of this flavonoid derivative adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. The material is manufactured under GMP-compliant conditions where applicable and is supported by a comprehensive Certificate of Analysis (COA). Quality assurance includes testing for identity, potency, and critical impurities to meet the exacting standards of the cosmetic and pharmaceutical industries. Certificates of Analysis (COA) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a 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 stability and purity.
