Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

surface tension at 20 °C is between 57 mN/m and 70 mN/m (OECD 115). The mean value is 64 mN/n.

Key value for chemical safety assessment

Surface tension:
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

The surface tension of the aqueous solution of both tested substances with a different monoester / diester ratio is between 57.2 and 70.2 mN/m at 20°C.

Due to the fact that the lowest surface tension is lower than 60 mN/m, the substance has surface-active properties.
