Description

Auroxanthin is a naturally occurring carotenoid pigment known for its distinctive color and biological activity. This compound is valued for its role as a precursor and intermediate in the synthesis of other valuable carotenoids and for its potential functional properties. It serves as a critical material for manufacturers in the nutraceutical, cosmetic, and food colorant industries, where high-purity, reliable sourcing is essential for product development and formulation.

Application

• As a key intermediate in the synthesis of other high-value carotenoids like violaxanthin and neoxanthin.
• As a pigment and colorant in premium cosmetic formulations, including lipsticks and eye shadows.
• As a functional ingredient in nutraceutical and dietary supplement products, leveraging its antioxidant potential.
• In research and development as a standard or reference material for analytical and biochemical studies.
• As a natural color additive for specialized food and beverage applications where synthetic colors are undesirable.
• For incorporation into animal feed supplements aimed at enhancing coloration and health in aquaculture and poultry.

Quality Control

Our Auroxanthin is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for nutraceutical and research applications. Comprehensive testing includes identity confirmation, purity assay, and impurity profiling. Certificates of Analysis (COA) documenting all test results are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) to minimize oxidation and degradation. The container should be kept in a cool, dry, and well-ventilated area away from incompatible materials.
