Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
no guideline followed
Principles of method if other than guideline:
The surface tension was measured with the capillary rise method by using n-heptane as secondary standard. The capillary rise was measured as described in Riedo F., Czencz M., Liardon, 0., Kovats E. sz. Helv. Chim. Acta 1878, 61, 1912.
GLP compliance:
no
Type of method:
other: capillary rise mrthod
