Cryptoxanthin
Description
Cryptoxanthin (CAS 472-70-8), also known as E161c, is a naturally occurring carotenoid pigment derived primarily from sources such as paprika and citrus fruits. It functions as a yellow-to-orange colorant and antioxidant across food, nutraceutical, and cosmetic applications.
In food and beverage manufacturing, E161c is approved for use as a natural colorant, delivering warm yellow and orange hues to products such as juices, dairy items, and confectionery. Nutraceutical and dietary supplement formulators incorporate it as a provitamin A source.
This positioning allows finished products to sit within the carotenoid supplement category. In cosmetic and personal care formulations, it is used to impart color and antioxidant activity in skin creams, serums, and color cosmetics.
Pharmaceutical manufacturers also evaluate it as a natural pigment for soft gel capsules and coating systems where synthetic dye alternatives are required. This versatility makes it a valuable ingredient for manufacturers seeking clean-label solutions.
Cryptoxanthin is supplied as a powder or oil suspension, with concentration and carrier varying by application. Food and supplement grades conforming to E161c specifications are the most commonly traded forms in the global market.
Buyers should confirm source material, extraction method, and carotenoid content with suppliers. These factors directly affect regulatory acceptance and formulation performance across different industrial sectors and geographic regions.
