Tetrahydrocurcuminoids (THC), a derivative of curcuminoids, is finding increasing acceptance in cosmetic applications. This compound is colorless, unlike the yellow curcuminoids. It could therefore be used in color free food and cosmetic products that currently employ conventional synthetic antioxidants. A set of studies performed by Sabinsa Corporation revealed that the Curcuminoids and THC are more potent antioxidants than the commonly used synthetic antioxidant, Butylated Hydroxy-toluene (BHT).

An antioxidant used in cosmetic applications should have the capability to efficiently quench free radicals on the surface of the skin. In this context, the studies performed by Sabinsa Corporation revealed the superior free radical scavenging ability of THC. In a standard test procedure known as DPPH (1,1 diphenyl-2-picrylhydrazyl)-radical scavenging method, Curcuminoids and THC were shown to be effective antioxidants. Their efficacy is concentration dependent, with THC being more effective even at lower concentrations. Besides, THC has zero irritation potential on the skin.
