Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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): 
EC50(96h): 95923 mg/L ( 95.92 g/L)
Chronic Value for green algae: 12480 mg/L (12.48 g/L)

Key value for chemical safety assessment

Additional information

The prediction for acute and long-term toxicity for aquatic organisms of 1 -Propanesulfonic acid, 3 -mercapto-, monosodium salt 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 green algae an EC50(96h) of 95.92 g/L and a Chronic Value (ChV) of 12.48 g/L was predicted. No GLP criteria are applicable for the usage of this tool, but due to the fact that it is a scientifically accepted calculation method the estimations performed are reliable with restrictions and can be used for the chemical safety assessment.
