- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM 01331 - 11 Standard Test Methods for Surface and lnterfacial Tension of Solutions of Surface-Active Agents
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Surface tension:
- 68.7 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 vol%
- Conclusions:
- Surface tension of a solution of the test item: 68.7 mN/m
Therefore, according to this test, it was considered that the test material is not surface active (surface tension > 60 mN/m). - Executive summary:
The surface tension of a solution of the test item in ultrapure water was determined according to the OECD Guideline No. 115, using the ring method.
The result is: 68.7 mN/m
Therefore, according to this test, it was considered that the test material is not surface active (surface tension > 60 mN/m).
Reference
No significant change of the measured surface tension. Thus it can be concluded that equilibrium is reached. Thus the results obtained were averaged to give the surface tension of the solution.
The result is:
Surface tension of a solution of the test item: 68.7 mN/m
Therefore, according to this test, it was considered that the test material is not surface active (surface tension > 60 mN/m).

Key value for chemical safety assessment
- Surface tension:
- 68.7
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
