Additional information

No experimental studies investigating the hydrolysis of sorbitan C16-18 (even numbered) fatty acid esters, ethoxylated (1-6.5 moles ethoxylated) are available. However, in accordance with column 2 of Annex VIII 9.2.2.1 of Regulation (EC) No. 1907/2006, testing for hydrolysis is not required as the substance is considered to be readily biodegradable.
