Description of key information
For the substance, the following results of the two constituents were derived:
Constituent | Species | Guideline / Method | Result | Remarks |
Ethyl 2-methyl-3-pentenoate | Daphnia | ECOSAR esters | 48-h EC50: 8.0 mg/L | Key study, Rel. 2. Value derived from QSAR calculation using measured log Kow of 3.1. |
Ethyl 2-methyl-3-pentenoate | Green algae | ECOSAR esters | 72-h ErC50: 2.86 mg/L 72-h ErC10: 1.05 mg/L | Key study, Rel. 2. Value derived from QSAR calculation using measured log Kow of 3.1. |
Ethyl 2‐methylpentanoate | Daphnia | ECOSAR esters | 48-h EC50: 13.4 mg/L | Key study, Rel. 2. Value derived from QSAR calculation using measured log Kow of 2.76. |
Ethyl 2‐methylpentanoate | Green algae | ECOSAR esters | 72-h ErC50: 5.06 mg/L 72-h ErC10: 1.66 mg/L | Key study, Rel. 2. Value derived from QSAR calculation using measured log Kow of 2.76. |
The substance is a multi-constituent consisting of 62% Ethyl 2-methyl-3-pentenoate and 32% Ethyl 2‐methylpentanoate. Thus, the effect values of the substance were derived by calculating the weighted average of the effect values of two constituents. The effect values of the substance are listed below:
Species | Result | Remarks |
Daphnia | 48-h EC50: 9.84 mg/L | Weighted average of the effect values of the two constituents |
Green algae | 72-h ErC50: 3.61 mg/L 72-h ErC10: 1.26 mg/L | Weighted average of the effect values of the two constituents |
Additional information
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.
