β-Carotene CAS#7235-40-7
Highly Stable Natural Pigment
β-Carotene is one of the most stable natural pigments, resistant to degradation under normal storage when protected from light and air.Antioxidant and Pro-Vitamin A Activity
It acts as a powerful antioxidant and can be converted into vitamin A, supporting immune and eye health.Wide Industrial Applications
Extensively used in food, cosmetics, and supplements due to its safe colorant properties and nutritional benefits.Fat-Soluble and Solvent-Compatible
Dissolves well in non-polar solvents like hexane and chloroform, making it versatile for lipid-based formulations.
β-Carotene, a carotenoid, is widely found in nature and is one of the most stable natural pigments. It is a fat-soluble compound, appearing as an orange-yellow crystalline powder or shiny rhombohedral crystal. Sourced primarily from green plants and yellow-orange fruits, its diluted solution appears orange-yellow to yellow, intensifying in color with higher concentrations. Depending on solvent polarity, the color may shift slightly to reddish. β-Carotene is used in food products, cosmetics, and as a supplement due to its antioxidant properties and its role in vitamin A production.
