Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
GLP compliance:

Other quality assurance:
other: ISO 9001
Type of method:
ring method
Surface tension:
72.4 mN/m
Temp.:
20 °C
Conc.:
0.02 mg/L
Remarks on result:
other: See additional information below

The surface tension of the test substance does not have to be reported because the solubility was determined to be < 1 mg/L.

The surface tension of the supernatant (<1 mg/L test substance) is 72.4 mN/m. This is an insignificant decrease from the surface tension of water at 20.0°C. The test solution is water clear and less than 200 mPa s (200 centipoise). 

Conclusions:
The surface tension of the test substance does not have to be reported because the solubility was determined to be < 1 mg/L.
The surface tension of the supernatant (<1 mg/L test substance) is 72.4 mN/m. This is an insignificant decrease from the surface tension of water at 20.0°C. The test solution is water clear and less than 200 mPa s (200 centipoise). 

Description of key information

The surface tension of the test substance does not have to be reported because the solubility was determined to be < 1mg/L.
