Applicant's summary and conclusion
- Interpretation of results:
- practically nontoxic
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- After an application period of 24 hours followed by an observation period of 14 days, no mortality and other adverse effects were observed. L173 is non-toxic via the dermal route according to CLP
- Executive summary:
The acute dermal toxicity of L173 was assessed in a GLP guideline study according to OECD 402. 2000 mg/kg of the test item were applied on the skin of Wistar rats (5 females, 5 males). The exposure period was 24 h followed by an observation period of 14 days.
No mortalities and no other treatment related other adverse effects were observed.
The substance is considered non-toxic via the dermal route.
