Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other: REACH Guidance on QSARs R.6 (QSPR model adapted specifically from OECD 405 test guideline)
Principles of method if other than guideline:
The in silico study aims to predict the Acute Eye Irritation/Corrosion potential of the test item using the following QSAR models:
* Nexus DEREK v6.0.1
* OECD QSAR Toolbox v4.2 (profiling results)
The final consensus result for Acute Eye Irritation/Corrosion was derived by applying a consensus method on the reliable results derived for individual models.

As per the profiling results, the query substance will not be classified as eye irritant.

 

 

* Results with Nexus DEREK

No structural alerts for eye irritation were triggered. Therefore, the query substance can be considered as non-irritant to the eye using this tool.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
Based on multiple QSAR models applied, the test item was predicted as non-irritant to the eye.
