Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Based on the structure (hydrophilic functional group and long hydrophobic C-chain) surface active properties of this substance are to be expected.

The surface tension of the test item in aqueous solution was determined in a guideline study according to OECD guideline 115 applying the plate method.

The surface tension was determined to be 71.6 ± 0.6 mN/m at 90% of saturation concentration and 20 °C. Due to the very low solubility in water at room temperature the expected surface active properties of the main constituents can not be observed during surface tension measurements.
