In vivo

Results
Irritation parameter:
other: visual inspection
Time point:
other: 10-20 minutes
Reversibility:
fully reversible
Remarks on result:
positive indication of irritation
Remarks:
A slight transient erythema was observed after 10-20 minutes exposure to 1.5 mL n-hexane. Stinging and/or burning sensation reported by the volunteer. Application of 0.1 mL neat n-hexane did not cause clinical signs or affect blood flow.
Irritant / corrosive response data:
increased blood flow, slight erythema, stinging and/or burning sensation
fully reversible within 60 min.

Applicant's summary and conclusion

Interpretation of results:
Category 2 (irritant) based on GHS criteria
Conclusions:
Analogue substance n-hexane caused fully reversible skin irritation at a human volunteer.
