Key value for chemical safety assessment

Additional information

One study is available on the short-term toxicity of Sorbitan monolaurate, ethoxylated (CAS No. 9005-64-5) to algae.

The key study conducted with Sorbitan monolaurate, ethoxylated (CAS No. 9005-64-5) was performed according to OECD Guideline 201 and GLP (Wenzel, 2012). The test organism Pseudokirchneriella subcapitata was exposed to the test substance in a static system for 72 hours, at the nominal test concentrations of 1.0, 3.16, 10.0, 31.6 and 100 mg/L. The test solutions were prepared as water accommodated fractions (WAF). ErL50 and ErL10 values of 58.84 mg/L and 19.05 mg/L, respectively, were derived.
