Following the mandate given by the European Commission in March 2024, the SCCS (Scientific Committee on Consumer Safety) has assessed the safety of the hair dye ingredient HC Red No. 18, and has just published its preliminary Opinion. It is open for comments until 13 January 2025.
Background
HC Red No. 18 (CAS No.: 1444596-49-9, EC No.: -) can be used as an ingredient in oxidative hair dye formulations.
In 2015, an initial assessment by the SCCS concluded that the substace was safe at 1.5%, but that data on its purity and impurities needed to be provided. The industry submitted these in February 2024.
