- Details on results:
- The substance is a multi-constituent substance of limited solubility. CLP classification is available for the individual components of the substance via REACH Annex VI harmonised classifications, REACH Registration dossiers or notifications to the CLP inventory. As such, it is deemed inappropriate to conduct additional testing on the reaction mass subject to this registration when the results may be predicted on the basis of the components themselves. QSAR assessment using US EPA On-Line EPI Suite™ ECOSAR v1.11 model assessment of acute toxicity to Daphnia is utilised to assess each component with the exception of phenol (which carries significant data already), with the associated range of results reported. 48-h EC 50 results were obtained in the range of 0.394 to 3.1 mg/l. On the basis of an average value, Environment Category Chronic 2: H411: Toxic to aquatic life with long lasting effects is assigned.
- Results with reference substance (positive control):
- Not applicable - QSAR assessment
- Reported statistics and error estimates:
- Not applicable - QSAR assessment
- Validity criteria fulfilled:

- Conclusions:
- The substance is a multi-constituent substance of limited solubility. CLP classification is available for the individual components of the substance via REACH Annex VI harmonised classifications, REACH Registration dossiers or notifications to the CLP inventory. As such, it is deemed inappropriate to conduct additional testing on the reaction mass subject to this registration when the results may be predicted on the basis of the components themselves.
