Endpoint:
skin sensitisation, other
Remarks:
QSAR prediction
Type of information:
(Q)SAR
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Validated QSAR model
Justification for type of information:
The OECD QSAR Toolbox v3.3.5 is a Quantitative Structure-Activity Relationship model that was developed by the Laboratory of Mathematical Chemistry, Bourgas, Bulgaria (http://toolbox.oasis-lmc.org). It contains several different databases with data on chemicals. The model was used to predict the skin sensitisation potential of the test substance in the database 'Protein binding alerts for skin sensitisation by OASIS v1.3'.

Any other information on results incl. tables

The predicted skin sensitisation potential of the test substance as protein binding potential was modelled in the OECD QSAR Toolbox v3.3.5.The test substance falls within the model applicability domain for the database OASIS v1.3.No alerts were found. Therefore, the test substance is not expected to exhibit skin sensitising properties.
