Concerns
SCCP/0923/05
13 December 2005
The SCCP is of the opinion that the information submitted is insufficient to assess the safe use of the substance.
-
Information submitted insufficient to assess safe use; further information required before any consideration.
SCCS/1435/11
2011-12-14
Based on the data provided, Quinolinium, 4-formyl-1-methyl-, salt with 4-methylbenzenesulfonic acid (1:1) does not pose a risk to the health of the consumer when used as an oxidative hair dye (used in the absence or presence of hydrogen peroxide) with a maximum on-head concentration of 2.5%.
2.5%
Mutagenic in vitro (gene mutations in bacteria, chromosome aberrations in mammalian cells); in vitro positives not confirmed in vivo (negative micronucleus and UDS tests), so considered to have no in vivo genotoxic potential. Earlier SCCP/0923/05 had found data insufficient.
