Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There are no experimental data on aquatic toxicity available for the test item. Therefore, a read-across approach is applied.

Additional information

Short term toxicity to fish

There are no experimental data available for the test item. Therefore, a read-across approach is applied. The following LC50 values after 96 h of epxosure were obtained in fish for the respective source substance:

LC50 = 5.7 mg LAS TEA/L

LC50 = 1.67 mg LAS Na/L

LC50 = 460 mg DEA/L

Long term toxicity to fish

There is no experimental data available for the test item. Alternatively, a read-across approach is applied. As lowest threshold value the following value was obtained in fish for the source substance:

NOEC = 0.23 mg LAS Na/L

Short term toxicity to aquatic invertebrates

There are no experimental data available for the test item. Therefore, a read-across approach is applied. The following EC50 values were obtained for short-term toxicity to daphnia for the respective source substance:

EC50 = 18.8 mg LAS TEA/L

EC50 = 2.4 mg LAS Na/L

EC50 = 30.1 mg DEA/L

Long term toxicity to aquatic invertebrates

There is no experimental data available for the test item. Alternatively, a read-across approach is applied. The following values were obtained for the respective source substance:

NOEC = 0.5 mg LAS Na/L

EC10 = 1.18 mg LAS/L

NOEC = 2.9 mg C12LAS/L

Toxicity to aquatic algae

There are no experimental data available for the test item. Therefore, a read-across approach is applied. The following ErC50 values were obtained for toxicity to aquatic algae for the respective source substance:

ErC50 > 56.2 mg LAS TEA/L

EC10 = 17.3 mg LAS TEA/L

NOEC = 3.4 mg LAS TEA/L

ErC50 = 128 mg LAS Na/L (Scholz RL1)

EC10 = not determined

NOEC = 2.4 mg LAS Na/L (Scholz RL1)

ErC50 = 14.9 mg DEA/L

EC10 = 2.4 mg DEA/L

NOEC = not determined

Toxicity to microorganisms

There are no experimental data available on the test item. Therefore, a read-across approach is applied. An EC10 of 55 mg/L was determined for source substance 1 (LAS TEA). Source substance 3 (DEA) did not induce any effects to aquatic microorganisms under the conditions of the test up to a concentration of 1000 mg/L.
