Tetrahydrocurcumin ●
TL;DR. This ingredient is used as an antioxidant and tone-evening active in skin care. It helps protect formulas and skin surface lipids from oxidation while supporting the look of more even pigmentation.
What does Tetrahydrocurcumin do in a cosmetic formula?
This ingredient is used as an antioxidant and tone-evening active in skin care. It helps protect formulas and skin surface lipids from oxidation while supporting the look of more even pigmentation.
Is Tetrahydrocurcumin clean?
It is generally viewed as a low-irritation active with limited clean-standard friction. The main review points are supplier purity, residual solvents, and whether the material is naturally derived or nature-identical.
Is Tetrahydrocurcumin sustainable?
This material is commonly derived from a plant polyphenol through additional processing, so its footprint depends on agricultural sourcing and manufacturing controls. It is not known for major persistence concerns, but robust biodegradation data is less established than for simple plant oils or sugars.
Is Tetrahydrocurcumin COSMOS-approved?
It may be compatible with COSMOS-natural when made from permitted plant feedstocks using allowed processing, but certification depends on supplier documentation and manufacturing route. From a Green Chemistry perspective, it scores better when renewable feedstock, low-residue processing, and readily managed solvents are used.
How does Tetrahydrocurcumin work chemically?
The molecule is a hydrogenated polyphenolic diarylheptanoid with phenolic hydroxyl groups that support radical-scavenging behavior and improved color stability versus the parent chromophore. Typical cosmetic use is often around 0.05% to 1%, with best performance in well-solubilized systems and protection from excessive heat, light, and high-pH conditions.
