Safety Profile
HC Yellow No. 12 has not been reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel. It is explicitly listed under Annex II / 1325 of Regulation (EC) 2009/1223, indicating its prohibition in cosmetic products within Europe. While some sources describe it as 'generally non-irritating,' there is also a noted 'likelihood of irritation,' particularly when formulated with other problematic ingredients. Its regulatory status severely restricts its application in skincare.
