Applicant's summary and conclusion

Interpretation of results:
Toxicity Category IV
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The acute oral median lethal dose (LD50) of tert-butyl-4-methoxyphenol in mouse was found to be 1100 mg/kg of body weight. Acute oral toxicity of tert-butyl-4-methoxyphenol to mouse by oral route indicates that tert-butyl-4-methoxyphenol exhibits acute toxicity by the oral route in the Category 4 which is relatively non toxic.
Executive summary:

The acute oral median lethal dose (LD50) of tert-butyl-4-methoxyphenol in mouse was found to be 1100 mg/kg of body weight. Acute oral toxicity of tert-butyl-4-methoxyphenol to mouse by oral route indicates that tert-butyl-4-methoxyphenol exhibits acute toxicity by the oral route in the Category 4 which is relatively non toxic.
