Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The paper concludes that the irritant rating of sodium trimetaphosphate in rabbits is a non-irritant.
This study is considered to support a conclusion of no classification under Regulation (EC) No. 1272/2008 (EU CLP), as part of a weight of evidence approach, as the the data clearly shows that at all time points and for relevant parameters no effects were observed.
