Tetrahydrocurcumin
Product Description:
Tetrahydrocurcumin (THC) is the most active and principal intestinal metabolite of curcumin. It
comes from hydrogenated curcumin that is from turmeric root. THC has a great effect of skinwhitening. Also it can prevent the production of free radicals, and eliminate free radicals that have formed. So, it has obvious antioxidant effects, such as anti-aging, repairing skin, diluting 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.

Tetrahydrocurcuminoids VS Curcumin
| Tetrahydrocurcuminoids | Curcumin | |
| Source | Hydrogenated derivatives of curcumin. | Extracted from the rhizome of turmeric. |
| Specification | 98% | 95% |
| Molecular structure |
|
|
| Tetrahydrocurcumin' 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. | ||
| Property | High stability, more antioxidant. Bioavailability is higher than curcumin | 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 Arbutin | Health care and functional food. |
Function:
1. Skin-whitening
Tetrahydrocurcumin can inhibit tyrosinase effectively. It has great potency of antioxidant and
ability to capture free radicals, which are the main reason for its skin-whitening effect. In some
beauty industries, people apply the mixture of THC powder, milk and egg white on the face. As
a result, the face became whiter significantly after two weeks.
2. Anti-aging and anti-wrinkles
Scientific studies have shown that THC is effective to protect cellular membrane damage that is
caused by lipid peroxidation. And its antioxidant effect is better than other hydrogenated
curcumin so that it can be against wrinkles availably and prevent skin aging.
3. Anti-inflammatory effect
Turmeric is commonly used as a traditional medicine to heal wounds and remove scars in India.
And THC extracted from turmeric has a strong anti-inflammatory and antibacterial effect, which
can effectively reduce pain as well as swelling and repair skin. It has obvious functions to cure
slight burn wound, skin inflammatory and scars.
Applications:
Tetrahydrocurcumin is widely used in various skin care products of skin-whitening, freckle, and anti-oxidation, such as creams, lotions and essence.
