Description of key information

Data waived - Study scientifically not necessary / other information available

- In accordance with Column 2 of REACH Annex IX, the study does not need to be conducted.  The substance does not contain relevant functional groups for which an assessment of the dissociation behaviour would provide information for risk assessment purposes. Therefore, the determination of a dissociation constant is not considered to be required (Guidance on information requirements and chemical safety assessment; Chapter R.7a: Endpoint specific guidance, section R.7.1.17.1).
