Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The static, 48-hour test was conducted on Daphnia magna (< 24 hours old) with concentrations ranging from 500 to 10000 mg/L.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 720 mg/L
Additional information
No short-term toxicity to aquatic invertebrate data were available for the test substance. Therefore, an acute aquatic invertebrate toxicity study with potassium sulphate was used as a read across to fulfill the data gap for the test substance. The underlying hypothesis for the read-across is that the test substance hydrolyses to form sulphuric acid and potassium sulphate. At environmentally relevant pHs, sulphuric acid will ionise to form its respective sulphate ion. In water, potassium sulphate will dissociate to form potassium and sulphate ions. The potassium sulphate study was selected since the relevant species of concern is the potassium cation. Additional documentation, provided within the IUCLID Assessment Reports section, supports the read-across approach.
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.
