Additional information
Conclusion on classification
The test material is readily biodegradable and the most reliable NOEC (for long term toxicity to Daphnia magna) is > 1 mg/L. Hence, it is unnecessary to classify the substance as hazardous to the environment under the terms of Directive 67/548/EEC or GHS as reflected by Regulation (EC) 1272/2008 and adapted by Regulation 286/2011.
