Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- None
- Clinical signs:
- other: No symptoms of poisoning were observed at any time during the follow-up period
- Gross pathology:
- The macroscopic assessment of the animals killed at the end of the observation period revealed that all animals had a lung with dark red spots (= increased blood-flow). Experience has shown that this finding is not substance-related and results from the method of asphyxiation used.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, the acute dermal LD50 of Locron P towards female Wistar rats is > 2000 mg/kg bw. Therefore, it is not classified according to the annex VI of the Regulation (EC) No. 1272/2008 (CLP) and to the GHS.
- Executive summary:
In an acute dermal toxicity study according to methodology comparable to OECD Guideline 402, 6 female Wistar rats were exposed to Locron P at 2000 mg/kg bw during 24 hours. After the exposure period, the dressing was removed and the treated skin area was rinsed with lukewarm water to remove the remaining test substance. At the end of the observation period, the surviving experimental animals were killed by CO2 gas, dissected and examined for macroscopically visible changes.
No mortality and no clinical signs were observed during the observation period.
Dark red spots in lung (= increased blood-flow) were observed in all animals. Experience has shown that this finding is not substance-related and results from the method of asphyxiation used.
LD50 was found to be > 2000 mg/kg bw
Under the test conditions, the acute dermal LD50 of test substance Locron P is higher than 2000 mg/kg bw. Therefore, the test substance is not classified according to the annex VI of the Regulation (EC) No. 1272/2008 (CLP) and to the GHS.
