Tetrahydrocurcuminoids (often abbreviated as THC) is a premium, colorless hydrogenated derivative of curcumin, extracted from the rhizomes of Curcuma longa. At China Extract Warehouse, our Tetrahydrocurcumin powder is produced using cutting-edge catalytic hydrogenation technology, resulting in a high-purity crystalline powder with a standardized active concentration of 95%-98%. Unlike the bright yellow of conventional curcumin, THC appears off-white to pure white, which completely eliminates the frustrating yellow staining issues of regular curcumin and makes it the ideal active ingredient for high-end cosmetic formulations and functional food products. It also delivers notably stronger antioxidant effects and far better physiological stability compared to ordinary curcumin. As a professional China-based manufacturing supplier, we strictly ensure that all our THC products are non-GMO, with rigorous quality checks on any potential solvent residues. Whether you want to purchase bulk THC for formulating skin brightening serums or anti-inflammatory dietary supplements, China Extract Warehouse provides the most competitive wholesale price and dedicated technical support among all global manufacturers in the category.

FAQ
★What is the difference between Tetrahydrocurcuminoids and regular Curcumin?
Tetrahydrocurcuminoids are colorless or off-white, while standard curcumin has a distinct bright yellow color. They have stronger antioxidant activity, better stability under light and heat, and will not stain skin or clothing. For these advantages, they are the preferred choice for skincare products and pale/light-colored finished food items.
★Is Tetrahydrocurcuminoids stable under heat and light?
Tetrahydrocurcuminoids are far more stable than regular curcumin. They resist degradation under UV light and high temperatures up to 120°C, making them perfectly suitable for baked goods, beverages, and cosmetic emulsions.
★What purity and specifications do you offer for Tetrahydrocurcuminoids?
We provide Tetrahydrocurcuminoids powder with ≥98% purity verified via HPLC. Our common available specifications include 95% and 98%, and we also accept custom blended formulation requests. All our powder products achieve 100% pass rate through 80 mesh sieve, with loss on drying controlled at ≤1%.
★Is Tetrahydrocurcuminoids soluble in water and oil?
THCu has excellent lipid solubility. In aqueous systems, it forms a uniform suspension with great dispersibility, which makes it suitable for both water-based and oil-based finished formulations.
★What production process is used?
Our complete production workflow follows these steps: turmeric rhizome raw material extraction → curcuminoid purification → catalytic hydrogenation (using Pd/C catalyst) → concentration → crystallization → drying → final milling. No harmful chemical residues are left in finished products, and the whole process is fully compliant with global food safety standards.
