Key value for chemical safety assessment
Additional information
There are no studies available on the toxicity of Sorbitan monolaurate, ethoxylated (CAS No. 9005-64-5) on terrestrial macroorganisms. In accordance to Regulation (EC) No. 1907/2006 Annex XI, 1.5, the assessment was therefore based on studies conducted with the analogue substances Sorbitan, octanoate (2:3) (CAS No. 91844-53-0) and Anhydro-D-glucitol trioleate (CAS No. 26266-58-0). These read across are justified in detail in the analogue justification in IUCLID Section 13.
The key study conducted with Sorbitan, octanoate (2:3) (CAS No. 91844-53-0) was performed as a limit test according to OECD guideline 207 and GLP (Simon, 2012). The test organism Eisenia fetida was exposed to the test substance in artificial soil for 14 days, at the nominal test concentration 1000 mg/kg. No mortality occurred during the test period.
The key study conducted with Anhydro-D-glucitol trioleate (CAS No. 26266-58-0) was performed as a limit test according to OECD guideline 207 and GLP (Harris, 2012). The test organism Eisenia fetida was exposed to the test substance in artificial soil for 14 days, at the nominal test concentration 1000 mg/kg. No mortality occurred during the test period.
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.
