Additional information
Justification for classification or non-classification
Based on the above results, the Daphnia study provides the lowest toxicity endpoint. This result is determined by the low limit of solubility of the tested substance (Similar Substance 02) in the test medium. It is highly probable that the toxicity level of the test substance is greater than 100 mg/l, which is the upper limit of classification.
However, using a conservative approach, the test substance has been classified as Category Chronic 4.
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.
