Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Calculation with ECOSAR v1.00 (EPIWIN software by US-EPA), Chronic Value for fish: 8130 g/L 

Key value for chemical safety assessment

Additional information

The prediction for long-term toxicity for aquatic organisms of the substance 1-Propanesulfonic acid, 3-mercapto-, monosodium salt (MPS) was determined by the computer program ECOSAR v1.00 (EPIWIN software) by US-EPA (Chemservice S.A., 2011). The program uses an extensive set of structure-activity relationships (SARs) to estimate the toxicity of chemicals discharged to water. For fish a Chronic Value (ChV) of 8130 g/L was predicted. However, since this value reveals only a concern of toxicity and no numerical value, it cannot be taken into account for the chemical safety assessment.
