Additional information

This dossier is a registration update of a previously notified substance and contains the info on the required endpoints under the previous legislation. In addition, this substance is notified as a well contained transported isolated intermediate.

Conclusion on classification

Based on the availlable data, viz. LC/EC50 values > 100 mg/L in the acute studies and chronic endpoints greater than 1 mg/L; namely an EC10 value of 25.6 mg/L in a chronic daphnia study, and an ErC10 of 31 mg/L in the algae study no environmental classification is needed for PDTN.
