Additional information
Conclusion on classification
2-Propenoic acid, methyl ester, reaction products with 2-ethyl-1-hexanamine and sodium hydroxide (methanol free) has been tested for toxicity to fish (Cyprinus carpio: 96h-LC50 = 42 mg/L), daphnids (48h-EC50 > 100 mg/L) and algae (72-ErC50 = 1.9 mg/L / 72h-ErC10 = 0.43 mg/L). Considering the fate properties of the substance (readily biodegradable, not potentially bioaccumulable based on a log Kow < 3), this leads to a classification as Aquatic Chronic 3, H412 according to the CLP classification criteria for environmental hazards (Aquatic Acute 2, H401 + Aquatic Chronic 3, H412 according to the UN-GHS classification criteria for environmental hazards).
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.
