Conclusion on classification
The aquatic toxicity data of the substance is not available. The substance is a multi-constituent consisting of 62% Ethyl 2-methyl-3-pentenoate and 32% Ethyl 2‐methylpentanoate. Thus, the toxicity values of the substance were derived by calculating the weighted average of the effect values of two constituents.
Short-term aquatic toxicity data are available for two trophic levels (invertebrates and algae). The weighted average acute effect values of the substance for invertebrates (Daphnia) and algae (green algae) are 9.84 mg/L and 3.61 mg/L, respectively. Since the lowest acute toxicity value is > 1 mg/L, the substance does not need to be classified for aquatic acute hazard according to EU CLP (EC no. 1272/2008 and its amendments: Table 4.1.0; a).
Long-term aquatic toxicity data is only available with algae (green algae), in which a weighted average ErC10 value of 1.26 mg/L (> 1 mg/L) was derived. Furthermore, the substance is classified as readily biodegradable. The log Kow is 3 (< 4). No experimentally determined BCF value is available. According to CLP Figure 4.1.1, the chronic classification has to be determined based on the chronic value for algae according to Table 4.1.0, (b) ii, as well as the acute value for Daphnia according to Table 4.1.0, (b) iii, and the most stringent outcome should be leading:
- The substance has a chronic toxicity value of > 1 mg/L. Based on this information, the substance does not need to be classified aquatic chronic hazard according to Table 4.1.0, (b) ii.
- The acute toxicity value is > 1 mg/L but < 10 mg/L. The log Kow of the substance is 3. Based on this information, the substance does not need to be classified for aquatic chronic hazard according to Table 4.1.0, (b) iii.
Overall, it can be concluded that the substance does not need to be classified for aquatic acute and chronic hazard according to EU CLP (EC 1272/2008 and its amendments).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
