Conclusion on classification
Self classification
Acute Toxicity
Invertebrates are the most sensitive species in tests on short-term aquatic toxicity based on the acute EC50 of 16.0 mg/L. Taking into account the results obtained in the aquatic toxicity studies, the substance has not to be classified regarding acute toxicity to the environment according to the consolidated version of Regulation (EC) No 1272/2008 (dated 01 Jan 2017).
Chronic toxicity:
Since no long-term toxicity tests are available for 1,3-propanesultone, aquatic chronic classification is derived from results on acute tests. L(E)C50 values in short-term tests are in the range 10 – 100 mg/L. Since 1,3-propanesultone is assessed to be rapidly degradable in the environment due to abiotic and biotic processes the substance does not need to be classified regarding chronic toxicity according to the
consolidated version of Regulation (EC) No 1272/2008 (dated 01 Jan 2017).
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.
