Endpoint conclusion
- Endpoint conclusion:
- no study available
- Additional information:
Three QSARs predictions are available and considered as WoE (Kr.2)
Based on the results from evaluations using three QSAR models (Nexus Derek, Leadscope and Toxtree), 4-(2-hydroxypropan-2-yl)-1-methylcyclohexan-1-ol was predicted as non-sensitiser to skin. No structural alerts were identified for skin sensitisation using Nexus Derek and Toxtree and 4-(2-hydroxypropan-2-yl)-1-methylcyclohexan-1-ol was also predicted as negative for this endpoint based on a statistical QSAR model in Leadscope (h-CLAT model v2).
Justification for classification or non-classification
Harmonised classification:
The substance has no harmonised classification according to the Regulation (EC) No. 1272/2008 (CLP).
Self classification:
Based on the available data, the test substance is not classified as skin sensitizer according to the Regulation (EC) No.1272/2008 and to the GHS.
