Additional information
Conclusion on classification
Short-term toxicity results for fish, Daphnia and algae are available for the substance. The 96h-LC50 for fish was > 100 mg/L. The 48h-EC50 for Daphnia magna was 21 mg/L. The 72h-ErC50 and 72h-ErC10 for algae were > 100 mg/L. The 72h-NOErC was 100 mg/L. The substance is readily biodegradable.
Short-term (acute) aquatic hazard
According to Table 4.1.0(a) of the CLP regulation, the substance does not need to be classified for acute hazards as the 96h-LC50 for fish, 48h-EC50 for Daphnia and 72h-ErC50 for algae are all > 1 mg/L.
Long-term (chronic) aquatic hazard
The only available chronic value is the 72h-ErC10 for algae. The chronic classification has to be determined based on this chronic value according to Table 4.1.0 (b) (ii) (as the substance is readily biodegradable) and based on the available LC50 value for fish and EC50 value for Daphnia, and environmental fate data according to Table 4.1.0 (b) (iii). The most stringent outcome is leading:
- The 72h-NOEC value for algae is > 1 mg/L, therefore the substance does not need to be classified for chronic hazards based on this available chronic value.
- The 48h-EC50 value for Daphnia is > 10 - <= 100 mg/L, however the substance is rapidly biodegradable. Therefore, the substance does not need to be classified for chronic hazards based on this acute value.
It is therefore concluded that the substance does not need to be classified for acute or chronic environmental hazards according to the CLP Regulation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
