Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Remarks on result:
other: The CMC is determined to be in the range between 1300 – 2200 mg/L at pH 7. Also, the surface tension at 1 g/L has been determined to be in the range between 27 – 31 mN/m.The temperature range is 23-25°C
Conclusions:
The CMC is determined to be in the range between 1300 – 2200 mg/L at pH 7. Also, the surface tension at 1 g/L has been determined to be in the range between 27 – 31 mN/m. The temperature range is 23-25°C

Description of key information
