Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 415-490-5 | CAS number: 141773-73-1 HELVETOLIDE
Dissociation constant
Administrative data
- 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
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
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)).

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
