Description of key information

The acute toxicity of Octadecanoic acid, 9(or 10)-sulfo-, potassium salt (CAS-No. 67968 -63 -2) for green algae has been tested in the OECD 201 test with Pseudokirchneriella subcapitata. After 72 hour of exposure, an ELC50 > 207.6 mg/l was obtained.

Key value for chemical safety assessment

EC50/LC50 for freshwater algae:
207.6 mg/L
EC10, LC10 or NOEC for freshwater algae:
125 mg/L
