Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The acute dermal LD50 for sodium trimetaphosphate in rabbits was determined to be > 4640 mg/kg. Due to the lack of methodological details and the lack of details regarding the purity of the test material this study is not considered to be acceptable for the purpose of classification and labelling in accordance with Regulation (EC) no. 1272/2008 (EU CLP). This study supports the conclusion that trisodium trimetaphosphate is not considered to be acutely toxic via the dermal route.
