Additional information
Conclusion on classification
Short-term aquatic toxicity data are available for three trophic levels (fish, aquatic invertebrates, and algae). The lowest observed acute effect concentration is a 96-h LC50 value of 23 mg/L as derived from a study with fish (P. promelas). Adequate long-term aquatic toxicity data are not available at this point. The substance is readily biodegradable and has an experimental log Kow of <4. No experimental BCF data are available. Based on all this information, the substance needs not be classified for the environment according to regulation EC/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.
