Additional information
Conclusion on classification
Short-term toxicity results for fish, daphnia and algae are available for the substance. The L/EC50 and ErC50 are > 100, > 100 and > 90 mg/L, respectively. Based on the lowest available acute data, in this case algae, the substance does not need to be classified for acute aquatic hazard according to Table 4.1.0 (a) of CLP.
As only one reliable long-term toxicity endpoint is available from the algae study, chronic classification needs to be derived on both acute and chronic data and the worst case should be taken. Based on chronic data (ErL10 = 11.2 mg/L), 3-methyl sulfolane does not have to be classified according to CLP Table 4.1.0 b(i). In addition, in view of the substance not being readily biodegradable, having a log Kow – 0.4 and the lowest acute data being > 90 mg/L for algae, the substance does not need to be classified for long term aquatic toxicity according to Figure 4.1.1 and Table 4.1.0, (b) iii of CLP.
Based on above, 3 methyl sulfolane does not need to be classified for the environment according to EU CLP (EC 1272/2008 and its updates). M factor for acute and chronic toxicity is not applicable.
The substance does not have to be classified for aquatic hazard.
The substance is not PBT or vPvB.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
