Clarification to degradation and mutagenicity testing under REACH

ECHA clarifies the rules on accepting adaptations to degradation testing and requiring combined studies for mutagenicity. Companies need to take these changes into account when deciding whether to update their registrations.

ECHA considers that the chemical safety assessment does not allow registrants to omit submitting standard information on degradation from column 1 under REACH (Annex IX, section 9.2., column 2). Instead, this provision is a legal basis for registrants to propose, and ECHA to require, further testing on degradation if the substance’s chemical safety assessment indicates such a need. 

More information are available on the ECHA’s news release.
