  • Applications

    alpha-Zeacarotene, CAS 50657-19-7, is primarily used as a natural colorant and food additive to provide yellow-orange coloration in foods, beverages, and cosmetic formulations, and it may be used as a carotenoid ingredient in dietary supplement formulations. It also serves as a pigment in cosmetics and personal care to enhance color in creams, oils, and other skin care products. As a carotenoid, it is used as a colorant in animal feed to color poultry products such as egg yolks and meat. In coatings and inks, alpha-zeacarotene can function as a natural pigment. It may also be considered for nutraceutical or supplement formulations, subject to local regulations and formulation limits.
