Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
SUMMARY OF ACUTE ECOTOXICITY RESULTS OF THE REGISTRATION SUBSTANCE (READ-ACROSS)
Acute ecotoxicity values for SMCT (source substance) which are used as read-across to SMLT (registration/target substance)
| Test type | Guideline | Species | Endpoint | Value | Remark |
| Acute Fish | OECD 203 | Danio rerio | LC50 (96h) | 5.04mg/L | test mat. UVCB =100% a.i. |
| Acute Daphnia | OECD 202 | Daphnia magna | EC50 (48h) | 7.46 mg/L | test mat. UVCB =100% a.i. |
| Algae | OECD 201 | Desmodesmus sups. | ErC50 (72h) | >100 mg/L | test mat. UVCB =100% a.i. |
| Sludge respir, inhib. | OECD 209 | Non-adapted sludge | NOEC (3h) | 180 mg/L | test mat. UVCB =100% a.i. |
| Algae | OECD 201 | Desmodesmus sups. | ErC10 (72h) | 36 mg/L | test mat. UVCB =100% a.i. |
Lowest Acute L(E)C50 is a value of 5.04 mg/l for fish which is the key value for the CSA
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
