Additional information
Conclusion on classification
The substance is classified as Aquatic Chronic 2 according to Annex VI of Regulation (EC) No 1272/2008 (CLP regulation).
However as the substance hydrolyses immediately in contact with water, the properties of the hydrolysis products are regarded as relevant for environmental hazards. Recent data (Chronic toxicity to Daphnia) on the major and the most environmentally hazardous constituent of the hydrolysate fulfill the criteria for Aquatic Chronic 1, M-factor 1. When substance EC 401 -280 -0 was included to Annex VI of the CLP-regulation the classification criteria for classification based on chronic aquatic toxicity data were not implemented. Thus, this more stringent classification of Aquatic Chronic 1 is used as self-classification for substance EC 401 -280 -0.
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.
