Scientific committee raises more concerns about hair dye safety
EU says Acid Orange 7 and Basic Red 51 among the culprits
The EU’s scientific committee on consumer safety has warned that using Acid Orange 7 as a hair dye ingredient up to a final on-head concentration of 0.5% under oxidative and non-oxidative conditions poses a health risk to consumers.
In another batch of recent papers the committee said further testing is needed to establish the gene mutation potential of hair dye ingredient 4-Amino-2-nitrophenyl-amine-2'-carboxylic acid. It added that data on its stability in an oxidative environment should be provided.
And while the committee has said the use of hair dye ingredient Basic Red 51 with a maximum on-head concentration of 1% in non-oxidative dye formulations is safe, it wants more information about its use in oxidative dyes, up to 0.5% on-head concentrations.
