Molecular Formula

Tetrahydrocurcumin’s structure is without unsaturated C=C compared to that of curcumin, so it lacks the conjugate double bonds that chromophore needs. Therefore, in terms of color,Tetrahydrocurcumin changes from yellow of curcumin to white powder

Character

High stability, mechanical stability, PH stability, thermal stability

More antioxidant,Bioavailability is higher than curcumin

No suspended matter after dispersion

Poor solubility,the structure is relatively unstable ,low bioavailability.

Function

Tetrahydrocurcumin is more stable and more antioxidant than curcumin,so it is more bioavailable and widely used, but the basic efficacy of both is the same: anti-inflammation,anti-OXidation, skin-whitening, remove freckle, promote wound repair( It is mainly shown in promoting the production of β-transformed growth factor (TGF-β)and collagen and the regeneration of epidermal cells.
Tetrahydrocurcumin's IC50 is 0.000492 ppm(curcumin is 0.730ppm, kojic acid is 9. 14ppm).whitening effect of Tetrahydrocurcuminis much better and its white color is more suitable for making cosmetics.

Application

High-end cosmetics,its whitening effect is even better than that of Arbution.
