About

A synthetic hair dye colorant that falls into the highest-concern bucket because the EU bans it from cosmetic use.

This ingredient is used as a hair dye colorant, but its Annex II listing means it is not allowed in EU cosmetics. Hair-dye materials in this class are also more likely than ordinary skincare ingredients to irritate skin or trigger allergy, so a very low score is the cautious call.

Function

HAIR DYEING

Known concerns

  • EU banned for cosmetic use
  • Hair dye sensitization risk
