Description

ε,ε-Carotene CAS NO 472-89-9 is a naturally occurring, all-trans isomer of β-carotene, a prominent member of the carotenoid family. This compound serves as a vital precursor to vitamin A (retinol) and is a powerful antioxidant, making it a high-value ingredient for nutritional and coloring applications. It is essential for manufacturers in the nutraceutical, food, beverage, and cosmetic industries seeking a pure, bioavailable source of pro-vitamin A activity and stable natural color.

Application

• Nutraceutical & Dietary Supplements: As a direct source of pro-vitamin A in capsules, tablets, and softgels for supporting vision, immune function, and skin health.
• Food & Beverage Fortification: Used to enhance the nutritional profile and provide a natural yellow-to-orange color in juices, dairy products, baked goods, and functional foods.
• Cosmetic & Personal Care: Incorporated into skincare formulations for its antioxidant properties, helping to protect the skin from environmental stressors and support a healthy complexion.
• Animal Feed & Aquaculture: Added to feed premixes for poultry, aquaculture (e.g., salmon), and livestock to improve flesh, skin, or egg yolk coloration and provide essential nutrients.
• Pharmaceutical Intermediates: Serves as a key starting material or intermediate in the synthesis of specialized retinoids and other pharmaceutical compounds.
• Research & Development: Used as a standard or reagent in biochemical, nutritional, and photochemical research studies.
