Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The acute dermal median lethal concentration (LC50) of 5-nitrosalicylic acid in rabbit was found to be 9862.85 mg/L.Acute toxicity of 5-nitrosalicylic acid to rabbit by the dermal route indicates that 5-nitrosalicylic acid does not exhibits acute toxicity by the dermal route within the doses mentioned.
Executive summary:

The acute dermal median lethal concentration (LC50) of 5-nitrosalicylic acid in rabbit was found to be 9862.85 mg/L.Acute toxicity of 5-nitrosalicylic acid to rabbit by the dermal route indicates that 5-nitrosalicylic acid does not exhibits acute toxicity by the dermal route within the doses mentioned.
