Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Study period:
12 September 2006 - 6 October 2006
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
yes
Remarks:
see below
Qualifier:
equivalent or similar to guideline
Guideline:
other: ISO 304 ring method
Deviations:
no
Principles of method if other than guideline:
Deviation: The surface tension result was not corrected using the Harkins-Jordan correction table as the correction is not applicable to the apparatus used. Once calibrated, the balance and ring assembly used in this test give a direct reading for surface tension that is within the required accuracy (± 0.5 mN/m); this is as a result of the reduced ring dimensions. This deviation has been considered not to have affected the integrity of the study.
GLP compliance:
yes (incl. QA statement)
Type of method:
ring method
Surface tension:
63 mN/m
Temp.:
22.4 °C
Conc.:
1 g/L
Conclusions:
The surface tension of a 1.00 g/L solution of test substance has been determined to be 63.0 mN/m at 22.4 ± 0.5°C. The test substance is considered not to be a surface-active material.
