Additional information
Justification for classification or not classification
In order to asses the toxicity of Dilasoft TF in aquatic compartment, data on its behaviuor in freshwater was taken into account. The substance resulted to be inherently biodegradable, however in order to achieve a conclusion on classification, a worst case scenario was considered and therefore the substance is considered to be as not readily biodegradable.
Studies carried out on on the three representatives taxonomic groups (algae, crustaceans and fish) of three throfic levels, show a slight toxic effect on all tested species and therefore the test substance is classified as Aquatic Chronic 3, according to the CLP Regulation (EC 1272/2008).
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.
