Tetrahydrocurcumin (THC) — THC 99%

Purity Levels

THC 99%

Tetrahydrocurcumin (THC) is the hydrogenated, colourless derivative of curcumin — it retains strong antioxidant activity while losing the yellow pigment and staining that limit curcumin's use in cosmetic and light-sensitive formulations. Mechotech's plant hydrogenates standardised curcuminoid extract to THC 99% purity for cosmeceutical, skincare, and advanced nutraceutical manufacturers.

Producing THC 99% requires a controlled catalytic hydrogenation step after standard curcumin extraction, converting the coloured curcuminoids into their colourless tetrahydro form without degrading the antioxidant structure. Mechotech's plant integrates curcumin extraction with a dedicated hydrogenation and purification line, built in SS 316L, WHO-GMP compliant, and delivered as a commissioned, performance-verified turnkey system that reliably reaches THC 99%.

Manufacturing Process

1

Curcumin Extraction & Standardisation

Turmeric rhizome is extracted and standardised to high-purity curcuminoid extract using closed-loop SS 316L extraction with solvent recovery, the feedstock for hydrogenation.

2

Catalytic Hydrogenation

Standardised curcuminoid extract undergoes controlled catalytic hydrogenation, saturating the double bonds that give curcumin its yellow colour while preserving the diarylheptanoid antioxidant backbone.

3

Catalyst Removal & Purification

The hydrogenated product is filtered to remove catalyst residue, then purified through crystallisation or chromatographic polishing to reach THC 99% purity.

4

Standardisation & Assay

The purified tetrahydrocurcumin is assayed by HPLC and adjusted to the declared THC 99% specification.

5

Drying & Quality Control

The standardised THC is dried to a free-flowing white-to-off-white powder, then released after assay, residual-solvent, catalyst-residue, heavy-metal, microbial, and moisture testing with full certificate of analysis.

Applications

  • Cosmeceutical and skincare antioxidant actives
  • Colourless nutraceutical and supplement formulations
  • Light-sensitive or clear-format product applications
  • Pharmaceutical antioxidant ingredient supply
  • Anti-inflammatory and dermatological formulations
  • Export to regulated-market cosmetic and pharma buyers

Key Features

  • Colourless, Non-Staining Output

    Catalytic hydrogenation removes the yellow pigment of standard curcumin while retaining antioxidant activity, suiting formulations where staining is unacceptable.

  • GMP-Compliant SS 316L Construction

    Electropolished SS 316L product-contact surfaces meet WHO-GMP and Schedule M requirements, with CIP operation between batches.

  • Integrated Catalyst Removal

    Dedicated filtration and purification stages remove hydrogenation catalyst residue to meet finished-product heavy-metal limits.

  • Standardised to THC 99%

    In-process and batch-release HPLC assay hold the finished tetrahydrocurcumin within its declared THC 99% specification.

  • Scalable Batch Capacity

    Plants are configured from pilot scale for product development to commercial batch sizes with modular expansion.

Frequently Asked Questions

What is tetrahydrocurcumin and how is it different from curcumin?
Tetrahydrocurcumin (THC) is curcumin with its double bonds saturated by catalytic hydrogenation. This removes the characteristic yellow colour and staining while retaining strong antioxidant activity, making it suitable for cosmetic and light-sensitive formulations where curcumin's colour is a drawback.
Does Mechotech supply the complete machinery for tetrahydrocurcumin production?
Yes. Mechotech supplies the complete turnkey plant — curcumin extraction, catalytic hydrogenation, catalyst removal, purification, and drying — engineered, fabricated at our Hyderabad facility, installed, and commissioned as a single performance-verified system.
What specification can the THC plant achieve?
The plant is engineered to reliably reach THC 99% purity, confirmed by batch-release HPLC testing with full certificate-of-analysis documentation.
How is hydrogenation catalyst residue controlled?
A dedicated filtration and purification stage removes catalyst residue after hydrogenation, with batch-release testing confirming heavy-metal limits are met before release.
Which industries use tetrahydrocurcumin?
Cosmeceutical, skincare, and dermatological formulators are the primary users, alongside nutraceutical and pharmaceutical manufacturers who need a colourless, non-staining antioxidant ingredient.
