Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:
Migrated from Short description of key information:
Weight of evidence across category suggests that nonanol, branched and linear is not a skin sensitiser. The key study was therefore read across from hexanol (Sharp 1978).

Justification for classification or non-classification

Based on weight of evidence across category, nonanol, branched and linear is proposed not to be sensitising to skin.
