Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Fatty acids, C8-10, Me esters (CAS 85566-26-3) will evaporate into the atmosphere from the water surfaces.

Key value for chemical safety assessment

Additional information

The Henry's Law constant was calculated (HENRYWIN v3.20) to be 97.3 - 171 Pa m³/mole (25 °C) for both main components. Additionally one experimental result for CAS-No. 111-11-5 cited in HENRYWIN v3.20 is available and supports the calculated results with an experimental Henry's Law constant of 79.3 Pa m³/ mol. Thus, the calculated Henry's Law constant indicates that the substance will evaporate into the atmosphere from the water surfaces.
