Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Toxicological information

Skin sensitisation

Currently viewing:

Administrative data

Endpoint:
skin sensitisation, other
Type of information:
(Q)SAR
Remarks:
TOXTREE
Adequacy of study:
weight of evidence
Reliability:
3 (not reliable)
Rationale for reliability incl. deficiencies:
results derived from a (Q)SAR model, with limited documentation / justification, but validity of model and reliability of prediction considered adequate based on a generally acknowledged source
Justification for type of information:
1. SOFTWARE
Toxtree (stimation of Toxic Hazard - Decision Tree Approach)

2. MODEL (incl. version number)

v3.1.0-1851

3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
F\C=C\F

4. APPLICABILITY DOMAIN
Toxtree is based on classification trees and does not provide such information and thus no reliability is assigned. All original model results are presented in the software printout section.

Applicant's summary and conclusion

Interpretation of results:
study cannot be used for classification
Conclusions:
It was identified in Toxtree in the Skin sensitisation reactivity domains an alert for SN2 nucleophilic aliphatic substitution was fired, suggesting a potential for sensitisation.
