Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 24 July 2018 to 31 August 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- Commission Regulation (EC) No 440/2008 of 30 May 2008 laying down test methods pursuant to Regulation (EC) No 1907/2006 of the European Parliament and of the Council on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), Method A.5. “Surface Tension”, Official Journal of the European Union L 142 of 31 May 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- Organization for Economic Co-operation and Development (OECD) Guidelines for Testing of Chemicals, Guideline No. 115, “Surface Tension of Aqueous Solutions”, adopted 27 July 1995
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Specific details on test material used for the study:
- No further details specified in the study report.
- Key result
- Surface tension:
- 72.1 mN/m
- Temp.:
- 21 °C
- Remarks on result:
- other: Conc. not specified
- Conclusions:
- The measured surface tension was multiplied by Φb resulting in a corrected surface tension of 72.1 mN/m.
As the surface tension value was higher than 60 mN/m, α,α’-Dichloro-p-xylene is classified as a non-surface active substance. - Executive summary:
The determination of the surface tension was carried out on the test item, with the use of a Krüss K11 Tensiometer by ring method. The value was found to be 72.1 mN/m at 21°C ± 0.5°C.
As the surface tension value was higher than 60 mN/m, α,α’-Dichloro-p-xylene is classified as a non-surface active substance.

RESULTS
The surface tension of the test item aqueous solution read on the instrument was 71.5 mN/m at 21°C ± 0.5°C using the ring method representing the mean of five measurements. The measured values were corrected with Harkins-Jordan correction factor.
The measured surface tension was multiplied by Φb resulting in a corrected surface tension of 72.1 mN/m.
As the surface tension value was higher than 60 mN/m, α,α’-Dichloro-p-xylene is classified as a non-surface active substance.
