Curcumin

Curcumin (CAS 458-37-7) is a naturally derived polyphenolic compound extracted from the rhizome of Curcuma longa, commonly known as turmeric. It is also referred to by regional names including Halad, Halud, and Haidr. No E-number is assigned under EU food additive regulations; it is handled as a botanical extract or active ingredient depending on application.

In food and nutrition, curcumin functions as a flavorant by contributing the characteristic earthy, slightly bitter notes associated with turmeric, while its conjugated beta-diketone structure enables it to neutralize free radicals, extending oxidative stability in fat-containing matrices. In personal care formulations, it absorbs UV radiation and acts as a skin protectant, making it relevant for sun care and anti-aging product development.

Curcumin is available in food-grade and cosmetic-grade forms, supplied as an orange crystalline powder. It is subject to REACH registration and can be sourced to FCC specifications for food applications. Standard packaging formats include fiber drums and multi-layer bags. HS code 29145000 applies for import classification.
