Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In this report the surface tension is determined using an automated tensiometer. The surface tension at 1 g/L has been determined to 30 mN/m at 23°C.

Key value for chemical safety assessment

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

Additional information

The only deviation from the method was that 2 g/L stock solution was used instead of 19 g/L due to poor solubility in water. The pH of the 2 g/L solution was adjusted by adding 0.1/1 M Hydrochloric acid and monitored with a pH meter.

In this report , the surface tension at 1 g/L has been determined to 30 mN/m.
