- Conclusions:
- Dissociation of any portion of the test substance is not possible. Therefore a waiver is appropriate.
- Executive summary:
Dissociation Constant
Justification For data Waiving (ECHA TGD ref 7.1.17)
From the compositional description and the structural formula given, it can be concluded that this substance 614-264-5(EINECS) is a highly oil soluble and incapable or becoming ionized fully or partially in the presences or absence of water or any other organic solvent. Taken collectively, these properties indicate a complete inability for this substance, or any functionality associated with it, to undergo dissociation to any measurable degree under any normal or adverse conditions of storage and handling. Thus, this analysis warrants a data waiver according to the assessment criteria normally applied during the evaluation of this physical property. This empirical evaluation is furthermore confirmed by long term handling experience.
