Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Two key studies and eight supporting studies showed that the nominal LC50 value is above 100 mg/L. In the both key studies (Danio rerio) a NOEC of 100 mg/L is reported. Four supporting studies were performed to assess the acute toxicity of the test item to Salmo gairdneri (Onchorhynchus mykiss). LC50 values from 125 to 200 mg/L nominal are reported. Four supporting studies were performed to assess the acute toxicity of the test item to Cyprinus carpio. LC50 values from 112 to 164 mg/l nominal are reported. In all supporting studies the died fishes showed a milky discoloration of the skin and pale red gills edges. These findings probably based on the high acidity of the substance and the low pH value.

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.
