Quality Control

Our cis-Y,Y-Carotene is produced and tested under strict quality management systems to ensure batch-to-batch consistency and purity. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as isomer purity, assay, and impurity profiles. While not pharmacopeial grade by default, production can be aligned with relevant standards for food or cosmetic applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C or as specified on the label. The container should be kept in a cool, dry, and well-ventilated area, away from heat sources and oxidizing agents. Allow the sealed container to reach ambient temperature before opening to minimize moisture condensation.
