Applicant's summary and conclusion
- Conclusions:
- The one generation reproductive toxicity LOEL (Lowest observed effect level)of tert-butyl-4-methoxyphenol was observed at a dose concentration of 35000 mg/kg bw (total dose) in a 4 week period was given to female 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 one generation reproductive toxicity LOEL (Lowest observed effect level) of tert-butyl-4-methoxyphenol was observed at a dose concentration of 35000 mg/kg bw (total dose) in a 4 week period was given to female 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.
