Key value for chemical safety assessment

Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
adverse effect observed (sensitising)
Additional information:

The result shows that the substance should be classified as a skin sensitiser

Migrated from Short description of key information:
N,N-dibutyldodecanamide was assessed for its skin sensitisation potential using the guinea pig maximisation test. 15 out of 20 guinea pigs, previously induced with N,N-dibutyldodecanamide elicited a dermal response 24 and/or 48 hours after challenge. There was no dermal response in any of the control animals. The net response was, therefore, 75% and N,N-dibutyldodecanamide is considered to be a skin sensitiser to the guinea pig.

Justification for classification or non-classification

The tests for skin sensitisation produced a response with 75% of the animals expsoed to the susbtance and the legislation requires the classification for a response of >30% of the animals tested.
