Safety
Safety Profile
CI 74180, also known as Direct Blue 86 or Acid Blue 87, faces complex regulatory scrutiny. Under EC Cosmetics Regulation (EC) No. 1223/2009, it is explicitly restricted to rinse-off cosmetic applications within the EU. While some regulatory frameworks suggest colorants undergo extensive toxicological testing, other authoritative sources, including interpretations by the EU Cosmetics Directive and the Personal Care Products Council, classify this ingredient as 'Unacceptable' or 'Banned,' citing safety concerns. Its regulatory status also applies in regions such as Brazil, the United Kingdom, and Serbia. A specific maximum concentration for its use has not been widely established in general safety assessments.
