Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information 20.9 Criteria used for interpretation of results: EU
- Conclusions:
- Based on the predicted MMAS score on rabbit eyes for piperazine adipate is estimated to be 20.9. Based on this value it can concluded that piperazine adipate is not classified as irritating to eyes as per the criteria of new CLP regulation and also MMAS value is less than 25.
- Executive summary:
Based on the predicted MMAS score on rabbit eyes for piperazine adipate is estimated to be 20.9. Based on this value it can concluded that piperazine adipate is not classified as irritating to eyes as per the criteria of new CLP regulation and also MMAS value is less than 25.
