Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 aquatic toxicity data requirements for SMLT are satisfied by read-across to the source substance SMCT (see section 13 for full read-across justification)

The lowest acute L(E)C50 for the source substance SMCT is a value of 5.04 mg/l for fish which is the key value for the CSA of SMLT
