Conclusion on classification

CLP Acute Toxicity Classification: Not Classified – conclusive although insufficient for classification, M-Factor: Not Applicable.

Notes: Acute classification based on an experimental 96-hour LC50 of >1000 mg/L nominal in Pimephales promelas and read across data that shows no toxicity observed at the limit of water solubility for Daphnia magna and Pseudokirchneriella supcapitata.

CLP Chronic Toxicity Classification: Not Classified – conclusive although insufficient for classification, M-Factor: Not Applicable

Notes: Chronic classification based on an experimental 96-hour LC50 of >1000 mg/L nominal in Pimephales promelas and read across data that shows no toxicity observed at the limit of water solubility for Daphnia magna and Pseudokirchneriella supcapitata . While an experimental 28-day COD of <0.01% and a Log Kow 5.0 suggests potential hazards, the Log HLC of 4.6 (dimensionless) shows little exposure to, and rapid removal from, the aquatic compartment.

Ozone Layer Hazard: Not Classified – conclusive although insufficient for classification.

Notes: FC-72 is not listed in the Montreal Protocol on Substances that Deplete the Ozone layer. It does not contain reactive halogen (chlorine or bromine) that could play a role in ozone depletion.

DSD: Not Classified – not dangerous to the aquatic environment.

Notes: Based on an experimental 96-hour LC50 of >1000 mg/L nominal in Pimephales promelas and read across data that shows no toxicity observed at the limit of water solubility for Daphnia magna and Pseudokirchneriella supcapitata. While an experimental 28-day COD of <0.01% and a Log Kow 5.0 suggests potential hazards, the Log HLC of 4.6 (dimensionless) shows little exposure to, and rapid removal from, the aquatic compartment.
