Tetrahydrocurcuminoids

Tetrahydrocurcuminoids (THC) are derived from curcuminoids (extracted from the roots of curcuma longa, commonly known as turmeric root). Tetrahydrocurcuminoids are phenolic in nature, acting as antioxidants, protecting against free radicals and preventing the generation of free radicals.

The efficacy of Curcuminoids and THC is also concentration dependant, with THC being even more effective at lower concentrations. THC also helps to improve the shelf life of topical formulations by inhibiting the autoxidation of fats by offering protection against rancidity of the fat components used in the formulation of cosmetics.

Curcumin/turmeric is also used as a pigment (like in self tanners).
