Crocin

Crocin (CAS 42553-65-1), also known as alpha-Crocin, Crocin A, Crocin 4, and commercially as Gardenin, is a water-soluble carotenoid glycoside pigment derived primarily from saffron (Crocus sativus) and gardenia fruit. It carries no assigned E-code and is identified under EC number 255-881-6 with molecular formula C44H64O24.

In food and nutrition applications, Crocin functions as a natural colorant delivering yellow-to-orange hues through its conjugated polyene chromophore, with colour intensity directly dependent on concentration. In personal care formulations, it acts as a humectant and skin conditioner by binding moisture within the stratum corneum, while its antioxidant activity helps stabilise formulations against oxidative degradation.

Crocin is supplied as a powder and sourced to cosmetic and food-grade standards, subject to REACH registration requirements for EU market entry. Procurement teams should verify origin documentation and standardised crocin content, as purity varies significantly between botanical extraction sources.
