Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Sorbitan C16-18 (even numbered) fatty acid esters, ethoxylated (1-6.5 moles ethoxylated) exhibits a water solubility of 148 mg/L (at 20 °C), low volatilization potential (< 0.0001 Pa at 20 °C) and log Koc values between 2.5 and 17.3 (based on MCI). The molecular structure of the substance indicates a potential of surface active properties. Based on these physico-chemical properties a high part of the UVCB substance is expected to target sediment and soil while another fraction will be solved in water. However, the substance is readily biodegradable and thus expected to be eliminated in sewage treatment plants to a high extent. In case of environmental exposure the substance will rapidly biodegrade in all compartments.
