Additional information
The substance is rapidly hydrolysed to isophthalic acid (IPA) and HCl. The studies used for derivation of the PNECs for ICL are studies done using the major degradate IPA. Therefore, the environmental hazard assessment for this test substance will be based on the primary degradate, isophthalic acid.
Conclusion on classification
The substance has been classified according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008 as Conclusive but not sufficient for classification.
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.
