Crocetin

Crocetin (CAS 27876-94-4, EC 248-708-0, C20H24O4), also known as alpha-Crocetin, transcrocetin, and roceic acid, is a natural apocarotenoid dicarboxylic acid derived primarily from saffron (Crocus sativus) and gardenia fruit. It carries no assigned E-code and is referenced in research literature under NSC 407300.

In pharmaceutical and nutraceutical formulations, crocetin functions as an antioxidant by scavenging reactive oxygen species and modulating oxidative stress pathways at the cellular level. In personal care applications, this same radical-quenching mechanism supports skin protection claims. Food and nutrition manufacturers use it as a pigment source where saffron-derived colorants are required.

Crocetin is supplied as a solid material and is available in research and commercial grades. Procurement should confirm compliance with REACH registration requirements for EU import and use. Buyers should specify purity grade and batch documentation requirements at the time of inquiry, as specifications vary by supplier.
