Description of key information
No toxic effects up to the limit of water solubility for Danio rerio (OECD 203)
Key value for chemical safety assessment
Additional information
There is one study on fish toxicity available for Sorbitan monolaurate, ethoxylated (CAS No. 9005-64-5).
The key study conducted with for Sorbitan monolaurate, ethoxylated (CAS No. 9005-64-5) was performed as a limit test, according to OECD Guideline 203 and GLP (Teigeler, 2012). The test organism Danio rerio was exposed to the nominal test concentration of 100 mg/L, prepared as water accommodated fractions (WAF). No mortalities were observed at the test concentration, during the 96-hour test period, and a LC50 of > 100 mg/L was reported.
A short summary is available for an additional acute fish study conducted with for Sorbitan monolaurate, ethoxylated (CAS No. 9005-64-5). The study was performed according to a guideline similar to OECD Guideline 203, using Salmo gairdneri as test organism (Brown, 1987). The fis were exposed to test concentrations of 56, 100, 180, 320 and 560 mg/L for 96 hours. Mortality occurred at the two highest concentrations, and an LC50 of 383 mg/L is reported. The documentation is not sufficient to evaluate the reliability of this data.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
