Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

guideline study
Qualifier:
according to guideline
Guideline:
other: EEC Directive 79/831, 3.5

Remarks on result:
other: Mean values of 5 measurements

The test substance is only very slightly soluble in water.The solution measured in this experiment is thus the filtrate of a 1g/100mL slurry of test substance.

Conclusions:
The surface tension of test substance was determined to be 60.0 mN/m at 20°C, filtrates of a 1g/100mL slurry

Description of key information

The study provided was conducted to recognised testing guidelines and with GLP certification.

Key value for chemical safety assessment

Surface tension:
60
in mN/m at 20°C and concentration in mg/L:
10 000

Additional information

Based on the criteria as outlined in the OECD Guideline it is concluded that the test substance should not be regarded as being surface-active material.
