Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Acute studies on all three trophic levels were performed to investigate the aquatic toxicity of the test substance. 2-propylheptyl acrylate shows no toxic effects in the range of water solubility towards fish and aquatic invertebrates. Toxic effects were only found towards algae. Due to the photolytical instability of 2-propylheptyl acrylate the test concentrations of the test substance could not be quantified by analytical methods in this test. Therefore, the effect concentration was expressed as nominal concentration (ErC50 = 84.9 mg/L).
No data on long-term toxicity of the test substance to aquatic organisms are available. However, the chronic results of two analogy approaches (n-butyl acrylate, CAS 141-32-2; ethyl acrylate, CAS 140-88-5) for aquatic invertebrates can be used for assessment. The most sensitive NOEC of 0.14 mg/L (reproduction) was obtained for Daphnia magna after 21 days of exposure to n-butyl acrylate.
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.
