Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Data from secondary source which meets basic scientific principles. Due to structural similarities of the registered substance trans-ß-ionone (CAS 79-77-6) and the used test substance ß-ionone (CAS 14901-07-6) the study data could be taken into account for assessment.
