Additional information

The dossier has been updated referring to Directive 1907/2006 EG (REACh); Article 22(1); (e), (g).

DNEL and PNEC values derived in the earlier version of the dossier have been removed due to the reasons already discussed in section 7.1.

The intake of 2.2 g L-Cysteine is a realistic value for daily intake of an adult European individual (EFSA). Based on the available information there is no indication of a bioaccumulation potential and secondary poisoning is of no concern. L-Cysteine has no potential to cause toxic effects if accumulated via the food chain.

Conclusion on classification

Due to the low ecotoxicity no classification is necessary.
