Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Based on read across studies for long-term toxicity to aquatic invertebrates on chemically similar substances, for the target substance Fatty acids, C14 -18 and C16 -18 -unsatd., ammonium salts the NOEC(daphnia, 21d) is estimated to be >=0.11 mg/l  (to <= 0.48 mg/l).

Key value for chemical safety assessment

Fresh water invertebrates

Fresh water invertebrates
Effect concentration:
0.11 mg/L

Additional information

Several publications are available in which the long-term toxicity to aquatic invertebrates of the analogue substances (Sodium oleate, Sodium myristate, Sodium stearate) were determined. The test duration was 21 days. As results, the following NOEC values were determined: 0.11 mg/L for Sodium oleate, 0.29 mg/L for Sodium myristate and 0.48 mg/L for Sodium stearate.

Based on the structural similarity of the target substance to the analogue substances the results of the long-term toxicity to aquatic invertebrates of the source substances can be assigned to the target substance.
