Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Executive summary:
The single dermal administration of Dimethylenpropanol to male and female rats at the dose of 2000 mg/kg was tolerated without any mortality or compound-related clinical or macroscopic pathological signs. No local intolerance reactions at the application sites were observed. The mean value grades across the time points (24, 48 and 72 h after removal of the pad) were 0 both for reddening/scab formation and for swelling.
