Description of key information

No effects up to the limit of water solubility for Daphnia magna (OECD 211)

Key value for chemical safety assessment

Additional information

One study is available on the long-term toxicity of Sorbitan, (Z)-9-octadecenoate (2:3) (CAS No. 8007-43-0) to aquatic invertebrates.

The key study conducted with Sorbitan, (Z)-9-octadecenoate (2:3) (CAS No. 8007-43-0) was performed according to OECD guideline 211 and GLP (Parr, 2013). The test organism Daphnia magna was exposed to the test substance in a semi-static system for 21 days, at nominal concentrations of 10, 18, 32, 56 and 100 % v/v. Since no effects occurred, the concentration 100 % v/v was determined to be the nominal NOEC. The corresponding time-weighted mean measured NOEC is thus ≥ 0.11 mg/L.
