Curcumin Turmeric Extract (CAS 458-37-7) is a highly purified natural extract derived from the rhizomes of Curcuma longa L. (Turmeric), standardized to 95% total curcuminoids by HPLC. It appears as a vibrant orange to reddish-orange fine powder with a characteristic mild earthy aroma. Our extract is produced through solvent extraction followed by crystallization and purification to concentrate the three key bioactive curcuminoids: Curcumin (diferuloylmethane), Demethoxycurcumin, and Bisdemethoxycurcumin.
Curcumin is the principal bioactive compound in turmeric, renowned for its exceptional anti-inflammatory, antioxidant, and skin-brightening properties. It inhibits multiple inflammatory pathways (NF-κB, COX-2, 5-LOX), suppresses tyrosinase activity for skin brightening, scavenges free radicals more effectively than vitamin E, and promotes wound healing — making it a versatile multifunctional active for anti-aging, brightening, acne-prone, and sensitive skin formulations.
