Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information 0.94 Criteria used for interpretation of results: EU
- Conclusions:
- By Modified maximum average score (MMAS) from prediction done using QSAR toolbox for eye irritation score of tert-butyl-4-methoxyphenol estimated as 0.94. This score indicates that tert-butyl-4-methoxyphenol is not irritating to the eye of rabbit.(as the criteria MMAS <25 is not irritating).
- Executive summary:
By Modified maximum average score (MMAS) from prediction done using QSAR toolbox for eye irritation score of tert-butyl-4-methoxyphenol estimated as 0.94. This score indicates that tert-butyl-4-methoxyphenol is not irritating to the eye of rabbit.(as the criteria MMAS <25 is not irritating).
