Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The alcohol tetradecanol is not irritating to human skin following a 4 hour semi-occlusive exposure.
The study was conducted accordint to GLP.
- Executive summary:
In the skin irritation study, undiluted test material was applied onto human skin and kept in contact to the skin under semi-occlusive dressing for 4 hours. Erythema and oedema scores were recorded at 1, 24, 48 and 72 hours after application.
No erythema and oedema were observed during the study period.
