Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

2009-10-20
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
yes
Remarks:

CMC is determined to 3.5 mg/L at pH 7. Also, the surface tension at 0.2 g/L has been determined to 30 mN/m.

Conclusions:
The CMC is determined to 3.5 mg/L at pH 7. The surface tension at 0.2 g/L is determined to 30 mN/m.
Executive summary:

The CMC is determined to 3.5 mg/L at pH 7. The surface tension at 0.2 g/L is determined to 30 mN/m.

Description of key information

The CMC is determined to be 3.5 mg/L at pH 7. The surface tension at 0.2 g/L is determined to be 30 mN/m.
