SOURCE SCCS Opinion 3 opinions

Opinion	Date	Conclusion	Max Conc.	Concerns
SCCP/1061/07	21 March 2007	safe	1.0%	sensitisation not excluded; secondary amine
SCCP/1059/06	2007-03-21	The SCCP is of the opinion that the information submitted is insufficient to allow a final risk assessment to be carried out. Before any further consideration - an in vitro percutaneous absorption study should be performed ... - an additional mutagenicity / genotoxicity test should be performed ... in order to exclude a gene mutation potential.	-	Insufficient data (missing in vitro percutaneous absorption study and additional mutagenicity/genotoxicity test to exclude gene mutation potential). Extreme sensitiser (LLNA EC3 0.2%). Mutagenic in Salmonella TA98 and clastogenic in human lymphocytes in vitro.
SCCP/1207/08	2008-12-16	The SCCP is of the opinion that, apart from the risks associated with the use of an extreme sensitiser, the use of 4-amino-3-nitrophenol as an ingredient in oxidative hair dye formulations with a maximum on-head concentration of 1.5% and in non-oxidative hair dye formulations with a maximum on-head concentration of 1.0% does not pose a risk to the health of the consumer.	1.5% on-head (oxidative); 1.0% on-head (non-oxidative)	Extreme sensitiser; studies on genotoxicity/mutagenicity in finished hair dye formulations should still be undertaken.
