The colourless side of curcumin

Tetrahydrocurcumin is the hydrogenated metabolite of curcumin, the active molecule of turmeric. Because the conjugated double bonds that give curcumin its intense yellow colour are saturated, tetrahydrocurcumin is colourless, which removes the staining limitation that keeps most turmeric-derived actives out of leave-on skin care.

T-pur99® is Azeco’s high-purity cosmetic grade of tetrahydrocurcumin. It combines antioxidant activity with support for a more even, brighter-looking skin tone, and its stability and compatibility with modern skin care systems make it suitable for serums, creams, emulsions and targeted treatments.
