Tetrahydro curcumin (THC), as the active and main metabolite of curcumin produced in organisms, is hydrogenated from curcumin isolated from the rhizomes of turmeric plants in the ginger family. Tetrahydrocurcumin is the main whitening active ingredient in natural turmeric root extract. It not only has the strongest tyrosinase inhibitory activity in Chemicalbook, but also has excellent chemical stability. Moreover, it appears as an odorless white powder, overcoming the chemical instability of ordinary turmeric extract that can easily cause skin staining. Ordinary turmeric extract is yellow in color, with poor chemical stability and photosensitivity. Under light exposure, it is prone to chemical reactions with the skin, leading to skin staining. Tetrahydrofluorocurcumin (THC), as the active and main metabolite of curcumin produced in the body, is hydrogenated from turmeric isolated from the rhizome of the ginger plant in the ginger family. Tetrahydrocurcumin is the main whitening active ingredient in natural turmeric root extract. It not only has the strongest tyrosinase inhibitory activity, but also has excellent chemical stability. Moreover, it appears as an odorless white powder, overcoming the chemical instability of ordinary turmeric extract that can easily cause skin staining.
