Conclusion on classification
Classification-related information
Biodegradation: not readily biodegradable (OECD 310)
Partition coefficient: log Pow = 4.7 at 35 °C and neutral pH (OECD 117)
Hydrolysis: The hydrolysis of the substance in aqueous test media was assessed in a stability test (please see IUCLID section 4.8). The mean concentrations of the test item decreased from initially 1.06 mg/L (corresponding to 103 % of nominal) at the start of the test to 0.213 mg/L (corresponding to 21 % of nominal) after 24 hours. The mean concentrations of DMOE increased from initially 0.0053 mg/L to 0.352 mg/L after 24 hours. These results demonstrate that the substance rapidly hydrolyses to Dimethyl octenol (DMOE).
Ecotoxicological data
Aquatic short-term toxicity
Aquatic invertebrates: 48-hour EC50 = 39 mg/L (nominal, D. magna, OECD 202, read-across)
Aquatic algae: 72-hour EC50 (growth rate) = 64 mg/L (nominal, P. subcapitata, OECD 201, read-across)
Aquatic long-term toxicity
Aquatic algae: 72-hour EC10 (growth rate) = 27 mg/L (nominal, P. subcapitata, OECD 201, read-across)
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The substance was assessed to be not readily biodegradable. Moreover, it was demonstrated that the substance rapidly hydrolyses in aqueous media. The log Pow of the substance was determined to be 4.7 at 35 °C and neutral pH. In a study according to OECD 202 with Daphnia magna the 48-hour EC50 of the read-across source substance was 39 mg/L (nominal). In a 72-hour static test according to the OECD Guideline 201 with the source substance, using the freshwater green algal species Pseudokirchneriella subcapitata, the 72-hour EC50 and EC10 for the growth rate were determined to be 64 mg/L and 27 mg/L, respectively. Based on available data on, the substance is not classified for aquatic short-term (acute) toxicity, but classified and labelled as aquatic long-term (chronic) toxicity category 3 (H412 :"Harmful to aquatic life with long lasting effect") according to Regulation (EC) No 1272/2008 (CLP), as amended for the seventeenth time in Regulation (EU) 2021/849. The classification is triggered by the 48-h EC50 for Daphnia magna, which is above the threshold value for aquatic long-term (chronic) toxicity category 3 of 10 mg/L, the fact that the substance is not readily biodegradable, as well as by the log Pow of 4.7, which is slightly above the threshold value of 4 mentioned in table 4.1.0 of Annex I of the CLP Regulation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
