Commission science committee deems hair-colouring ingredient safe for EU use


The European Commission’s Scientific Committee on Consumer Safety (SCCS) has adopted its final Opinion on the safety of the hair dye ingredient, indigofera tinctoria.

It considers the chemical to be safe when used in non-oxidative condition hair-colouring products at on-head concentrations of up to 25%.

However, the SCCS said in its 3 April Opinion that a weak skin sensitisation potential “cannot be excluded”.

At the end of March, the Commission asked the committee to provide an opinion on the safety of the hair dye acid yellow 3 [mixture of the disodium salts of the mono- and disulfonic acids of 2-(2- quinolyl)-1H-indene-1,3(2H)-dione]. It has until December to respond.
