Additional information
Conclusion on classification
Acute aquatic toxicity:
In short-term aquatic toxicity tests (fish, daphnia, algae) no adverse effects were observed. These tests were performed up to the water solubility of the test item. Therefore, the test item is not classified and labeled according to Directive 67/5487EEC (DSD) and Regulation (EC) No 1272/2008.
Chronic aquatic toxicity:
2-propylheptyl acrylate was tested in an aquatic toxicity test with daphnia. The 48-hour EC50 for growth rate was 161 mg/L. Using the read across approach the 21-d NOEC was determined to be 0.14 mg/L. In addition, 2-propylheptyl acrylate was shown to be ready biodegradable. Thus, the substance has to be classified as environmental chronic toxic cat. 3 according to Regulation (EC) No 1272/2008 (CLP) and with R52/53 according to Directive 67/548/EEC (DSD).
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.
