Applicant's summary and conclusion

Conclusions:
The repeated dose toxicity LOEL (TDLo - Lowest published toxic dose) of tert-butyl-4-methoxyphenol was observed at a dose concentration of 63000 mg/kg bw (total dose) in a 6 weeks study period where the dosage of tert-butyl-4-methoxyphenol was continuously given to rats orally.This indicates that tert-butyl-4-methoxyphenol shall not exhibit toxic effect to rat by the oral route below the above mention dose.
Executive summary:

The repeated dose toxicity LOEL (TDLo - Lowest published toxic dose) of tert-butyl-4-methoxyphenol was observed at a dose concentration of 63000 mg/kg bw (total dose) in a 6 weeks study period where the dosage of tert-butyl-4-methoxyphenol was continuously given to rats orally.This indicates that tert-butyl-4-methoxyphenol shall not exhibit toxic effect to rat by the oral route below the above mention dose.
