Premium plant extracts and custom formulations built under rigorous quality controls for global distribution.
Benefiting from the solid foundation provided by its parent company, Xi'an Tianben Bioengineering Co., Ltd., Botanical Cube Inc. focuses on researching, developing, producing, and selling healthy natural ingredients. With more than two decades of dedicated phytochemistry industry experience, we have positioned ourselves as a global leader in high-purity natural extracts and personalized custom biological formulations.
Our operational capabilities are robustly supported by three collaborative companies—Xi'an Tianben Bioengineering Co., Ltd., Botanical Cube Inc., and Shaanxi Tianben Kangyuan Biotechnology Co., Ltd. Together, we manage three state-of-the-art production bases covering more than 100 acres, with the combined power to process over 3,000 tons of natural plant raw materials each year. Our product portfolio exceeds 200 distinct plant extracts, offering diverse certified organic lines to meet strict international environmental and wellness paradigms.
Our foundational production facility, the Sanyuan Factory, was established in 2012 in Sanyuan City, Shaanxi, just four years following our corporate founding. Over the past decade, we have heavily invested in automated controls, scientific training, and strict analytical validation systems to build a robust framework of excellence.
Importantly, our extraction, milling, sifting, blending, and packaging stages are fully executed in an advanced Class 100,000 Cleanroom Environment. Operators follow strict sterile protocols, using specialized gowns, masks, and gloves. This sterile isolation ensures absolute zero cross-contamination, high microbiological purity, and standard compliance for cosmetic-grade and food-grade Tetrahydrocurcumin batches.
How we convert natural yellow curcuminoids into highly bioavailable, colorless Tetrahydrocurcumin (THC) at scale.
Traditional Curcumin exhibits intense yellow staining and low biological half-life. By running a controlled catalytic hydrogenation using premium palladium (Pd/C) or platinum catalysts under optimal temperature and pressure, the olefinic double bonds in the heptadiene chain are saturated. This chemical transition creates Tetrahydrocurcumin (THC), completely eliminating the yellow chromophore while retaining the high-performance diphenolic rings.
Cosmetic formulations require raw materials that do not discolor over time or stain the skin. Our Sanyuan Factory utilizes advanced recrystallization steps in organic solvents to yield an ultra-pure white to off-white crystalline powder (typically ≥ 98% purity by HPLC). Our processes ensure residual solvent levels are safely below standard USP <467> thresholds.
Since standard Tetrahydrocurcumin is highly lipophilic, our R&D center has developed a water-dispersible nano-liposomal and self-microemulsifying delivery system (SMEDDS). This tech modification raises active absorption rates in topical cosmetic applications and liquid health formulations, providing excellent stability against light degradation.
Traditional extraction yielding 95% yellow powder. Highly restricted usage in premium skincare formulations due to intense staining properties and low biological absorption limits.
Introduction of basic catalytic reduction processes. Improved skin compatibility and diminished staining, though background solvent traces and slight coloration remained hard to eliminate at scale.
Our current production technology. White crystalline powders with HPLC assay purity ≥ 98.0% alongside advanced liposomal delivery systems designed for high-end cosmetics and functional nutriceutical applications.
Aligning advanced active raw materials with global manufacturing standards for premium target industries.
Tetrahydrocurcumin is a powerful natural tyrosinase inhibitor, offering strong antioxidant protection. We supply top-tier cosmetics manufacturers with high-purity, non-staining white powder that easily blends into skin-brightening creams, daily anti-aging serums, and protective sunscreens without changing the formula's color.
Thanks to its potent anti-inflammatory properties, THC is widely used to support joint health, cardiovascular wellness, and cognitive function. Our raw materials are optimized for easy capsule filling, tablet compaction, and dry powder blends, ensuring excellent stability throughout their shelf life.
Our water-soluble nano-emulsion powders dissolve completely into functional liquids, clear RTD beverages, and wellness shots. This process delivers the full antioxidant benefits of curcumin without altering the product's taste, texture, or natural color.
Operating out of the Qinling mountain biological zone and the Xi'an high-tech corridor, Botanical Cube Inc. leverages a fully integrated local supply chain. From sourcing raw turmeric roots directly to utilizing state-of-the-art continuous extraction machinery, our operations are optimized to minimize waste and maximize energy efficiency.
Our three production bases guarantee supply safety for global distributors and bulk buyers. In addition, our automated inventory systems track batches from harvest to delivery, giving brands reliable lead times, stable pricing, and consistent product quality—even during global logistics disruptions.
Ensuring your raw materials align perfectly with global regulatory agencies and manufacturing compliance structures.
Every single production run undergoes extensive in-house and third-party laboratory verification. Testing parameters include HPLC fingerprinting, residual solvent analysis via GC-MS, heavy metals quantification (ICP-MS), and comprehensive microbial testing to meet EU and FDA standards.

Tailored particle size options, from standard coarse crystals to micronized powders, ensuring easy blending and processing in your existing manufacturing equipment.
Answers to common chemical, technical, and regulatory questions from cosmetic formulators and purchasing managers.
The main difference lies in chemical structure and appearance. Tetrahydrocurcumin (THC) is a hydrogenated derivative of curcumin. While standard curcumin has a bright yellow color and can stain skin or equipment, THC is colorless (white). In addition, because the olefinic bonds are hydrogenated, THC is more chemically stable, absorbs faster through the skin barrier, and offers stronger antioxidant action than standard curcumin.
We prevent discoloration by using advanced, multi-step recrystallization at our Sanyuan Factory. By monitoring the catalytic hydrogenation process in real time and using high-resolution HPLC testing, we ensure that yellow curcumin intermediates are completely converted. This leaves zero trace residues, resulting in a stable, off-white to pure white powder that will not yellow or discolor over time in cosmetic formulations.
For standard 98% Tetrahydrocurcumin powder, our minimum order quantity starts at 1 kg for formulation testing and climbs to 25 kg (one full drum) for commercial production. Standard stock items ship within 3 to 5 business days, while customized solutions or specialized mesh sizes generally require 10 to 14 working days, depending on our cleanroom production schedules.
Tetrahydrocurcumin is sensitive to light, oxygen, and moisture. We recommend storing the material in its original sealed container, kept in a cool, dry place away from direct sunlight. Under these conditions, the powder has a shelf life of 24 months, with HPLC assay purity remaining well within specifications.
