Additional information

Favorable acute aquatic data (LC50 and EC50 values >100 mg/L) with a PNEC of 0.564 mg/L indicates no classification is necessary for TPnB. The substance is readily biodegradeable and has a low potential for bioaccumulation. No further testing is proposed for the aquatic environment.

Conclusion on classification

According to Chapter 4 VI of Directive 67/548/EEC, no classification is required, as all EC50>100mg/L.
