Injection provoked a weak to moderate irritation during the preliominary study. Topical occlusive route provoked a weak to moderate irritation due probably by tearing.

Evidence of sensitisation of each challenge concentration:

None.

Other observations:

Positive control group with positive effect due to DNCB.

Interpretation of results:
GHS criteria not met
Endpoint:
skin sensitisation: in vitro
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
an in vitro skin sensitisation study does not need to be conducted because adequate data from an in vivo skin sensitisation study are available
Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)

Respiratory sensitisation

Endpoint conclusion
Endpoint conclusion:
no study available

Justification for classification or non-classification

The substance does not meet the criteria for classification in accordance with the classification, labelling and packaging regulation (EC 1272/2008).
