Additional information
The substance is officially classified as chronic cat.2 according to table 3.1 of Annex VI of Regulation (EC) No. 1272/2008. This Annex VI entry is a group entry for all monoalkaly or monoaryl or monoalkylaryl esters of acrylic acid. Test data with long-chained acrylates however clearly demonstrate that the substance has not to be classified with regard to environment. Nevertheless, due to the official Annex VI entry the respective PNECS were deduced and an environmental risk assessment is done for completeness sake.
Conclusion on classification
Based on the available study data on acute aquatic toxicity and data on chronic toxicity of the read across substances icosyl acrylate and dodecyl acrylate, the test substance 2-Propenoic acid, octadecyl ester has not to be classified and labelled according to Regulation (EC) No 1272/2008 (CLP).
Nevertheless, for the group of substances (monoalkyl or monoaryl or monoalkyaryl esters of acrylic acid) an entry in Table 3.1 of Annex VI of Regulation (EC) No 1272/2008 exists which will be adopted for safety reasons. Thus, the substance is classified as Aquatic Chronic cat. 2 ( H411: Toxic to aquatic life with long lasting effects.), according to Regulation (EC) No 1272/2008 (CLP).
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.
