Applicant's summary and conclusion

Interpretation of results:
study cannot be used for classification
Remarks:
Migrated information
Conclusions:
LD50 (dermal, rat) exceeds 2000 mg/kg bw
Executive summary:

In an acute dermal toxicity study according to OECD guideline 402 a group of 5 rats per sex were administered a limit dose of 2000 mg/kg bw by the dermal route for 24h. No adverse effects were noted, no clinical signs, no effects on body weight, no local signs and no adverse findings at final necropsy after a 14 days observation period.

The LD50 (rat, dermal) exceeded 2000 mg/kg bw.
