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 skin-whitening. 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.

2. Tetrahydrocurcumin Botanical Source

Turmeric (Latin name: Curcuma longa L.) is a perennial herb with a well-developed root of ginger family. It’s also known as Yujin, Baodingxiang, Madian, Huangjiang, etc. Leaves are oblong or elliptic, and corolla is yellowish.

Roots are the commercial sources of the traditional Chinese medicine “turmeric”. People pick out impurities in turmeric’s root, soak in water, then slice, and dry it. It can resolve stasis, promote menstrual circulation and relieve pain.

3. Tetrahydrocurcuminoids VS Curcumin

	Tetrahydrocurcuminoids	Curcumin
Source&Specification	Hydrogenated derivatives of curcumin. The market specification is 98%	Extracted from the rhizome of turmeric. The market specification is 95%
Color	White	Yellow
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 betterand 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.
