Description

.Beta.,.Epsilon.-Carotene-3,3-Diol, Hexadecanoate Octadecanoate, (3R,3R,6R)- is a specific, high-purity esterified carotenoid derivative, valued for its potent colorant and antioxidant properties. This compound matters for formulators seeking stable, oil-soluble color and bioactive ingredients derived from natural sources. It is primarily needed by manufacturers in the nutraceutical, cosmetic, and specialty food industries for applications requiring precise coloration and functional benefits.

Application

• Nutraceutical Formulations: Used as a key ingredient in dietary supplements and functional foods for its provitamin A activity and antioxidant capacity.
• Cosmetic & Personal Care: Incorporated into skincare products (creams, serums) and color cosmetics for natural pigmentation and skin-protective benefits.
• Specialty Food Coloring: Serves as a natural, oil-soluble colorant in fat-based food products, confectionery, and beverages.
• Animal Nutrition: Applied in feed premixes for poultry and aquaculture to enhance the coloration of egg yolks, skin, and flesh.
• Pharmaceutical Research: Utilized as a reference standard or an active pharmaceutical ingredient (API) intermediate in research and development.
• Advanced Material Science: Investigated for use in organic semiconductors and light-harvesting materials due to its conjugated polyene structure.
