Additional information
Conclusion on classification
Regarding all available data of the acute and/or chronic toxicity tests on aquatic organisms and taking into account the provisions laid down in Council Directive 67/548/EEC and CLP (GHS), the substance needs to be classified with respect to acute and chronic ecotoxicity (CLP Acute/Chronic Cat. 3). Hence, an exposure assessment environment is performed.
Hydrolysis product:
Acetaldehyde (CAS 75-07-0) is readily biodegradable. The log Kow is <4. The lowest acute effect concentration is 30.8 mg/L, the lowest chronic value is >> 1mg/L. Based on this information, the substance needs not be classified for the environment.
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.
