|---|---|---|---|---|
| SCCS/1301/10 | 22 June 2010 | Based on the information provided, the SCCS is of the opinion that the use of HC Yellow n° 9 as a non-oxidative hair dye ingredient at a maximum concentration on the head of 0.5% does not pose a risk to the health of the consumer. | 0.5% | A sensitising potential cannot be excluded. It is a secondary amine, prone to nitrosation/nitrosamine formation; should not be used with nitrosating substances; nitrosamine content should be < 50 ppb. |
