Administrative data

dissociation constant
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance has no ionic structure
Justification for type of information:
In accordance with REACh Annex XI section 1, the study does not need to be conducted.
Based on the chemical structures of the constituents, this substance does not contain relevant functional groups for which an assessment of the dissociation behaviour would provide information for risk assessment purposes, as no ionisation is anticipated, in particular under environmentally relevant pH range. Therefore, the determination of a dissociation constant is not considered to be required (ECHA endpoint specific guidance on information requirements and chemical safety assessment (R.7a, v6.0, July 2017, §R.7.1.17)).
