Qualifier:
according to guideline
Guideline:
other:
Version / remarks:
ECHA Guidance on information requirements and chemical safety assessment - Chapter R.06: QSARs and grouping of chemicals
Principles of method if other than guideline:
Prediction was calculated using QSAR Toolbox v.4.2.1
Data gap filling method: Trend analysis, executed via AW "Skin sensitization"
Justification for non-LLNA method:
The prediction is based on Guinea Pig Maximisation Test (GPMT) experimental existing data.
