Endpoint:
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

Description of key information

Triallyl cyanurate has no ionic structure. Therefore dissoziation in the relevant environmental pH range of pH 4 to 9 is not expected.

Supporting QSAR prediction confirms this assumption.

Key value for chemical safety assessment

Additional information

Triallyl cyanurate has no ionic structure. Therefore dissoziation in the relevant environmental pH range of pH 4 to 9 is not expected. Supporting QSAR prediction confirms this assumption. The used (Q)SAR estimation method of the software ACD Labs PhysChem Suite 2015 is valid for ionisable substances. The molecule can only be protonated in strong acid environment. The part of the molecule is Atom No. 18 at pH=2.3 +- 0,4 at 25 °C. Above this pH value of pH=4.0 no dissociation occurs. The substance will not be dissociate in water under environmental conditions. Only in strong acid environment below pH=2.3 a dissociation may be possible but not reliable for the environment.
