The evidence, graded
expert consensusSCCP/0902/05 (June 2005) could not assess the risk to consumers when CI 26100 is used as a colorant in cosmetic products. It noted an unquantifiable systemic carcinogenic risk and a relevant concern about skin carcinogenic potential. No studies had looked at its skin absorption or its breakdown to 4-aminoazobenzene. Older studies found no relevant skin irritation and no sign it sensitizes skin.SCCP 2005 · European Commission SCCP (adopted 21 June 2005) ↗
