Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- LMD is not irritating to skin at concentrations of up to 20%.
- Executive summary:
Three animals were exposed to solutions of 3% and 20% LMD for 4 hrs. After 4 hrs, the test substance was removed. The animals were observed for signs of irritation at 1, 24, 48, and 72 hrs after removal. Only minor irritation was seen in one animal at the 24 hr observation. The irritation was fully reversible by 48 hrs. LMD is therefore not irritating to the skin at concentrations of up to 20%.
