eliminate free radicals that have formed.
pigment, removing freckle, and so on. Nowadays, THC has been widely used as a natural whitening agent,and it enjoys vast
potentials in cosmetics industries.
Hongkang tetrahydrocurcumin product features:
1-Mechanical stability, PH stability, thermal stability.
2-Uniform product distribution with small particle size;No suspended matter after dispersion.
3-The color is white, which is more suitable for cosmetics (the products of most manufacturers are light yellow)


Function & Application

Function:

Skin-whitening
It has great potency of antioxidant and ability to capture free radicals, which are the main reason for its skin-whitening effect.

Product Name | Tetrahydrocurcumin | Curcumin |
Specification | 98% | 95% |
Color | White | Yellow |
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-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. | Health care and functional food |
