Quality Control

Our Ponceau 6R is produced and tested to meet stringent quality standards suitable for its target applications. We ensure compliance with relevant specifications such as FCC (Food Chemicals Codex) for food-grade material and other pharmacopeial guidelines where applicable. Certificates of Analysis (COA) documenting purity, heavy metal content, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

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