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:
- 08 September 2017 to 22 November 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Remarks on result:
- not determinable
- Remarks:
- The solubility of the sample was < 1 mg/L and therefore no further testing is required.
- Conclusions:
- In accordance with Column 2 of Annex VII (EC 440/2008) the endpoint is exempt as the water solubility is < 1 mg/L.
- Executive summary:
The surface tension of the test material was investigated in accordance with the standardised guidelines OECD 115 and EU Method A.5, under GLP conditions using the ring method.
A solution of 1 g/L was prepared. After shaking the majority of the sample sank to the bottom of the glassware. After 20 minutes sonication the sample remained insoluble. A second solution of 1 mg/L was prepared which sank to the bottom of the glassware. After 30 minutes of sonication the sample remained insoluble. The solubility of the sample was < 1 mg/L and therefore no further testing is required.
In accordance with Column 2 of Annex VII (EC 440/2008) the endpoint is exempt as the water solubility is < 1 mg/L.

Additional information
The surface tension of the test material was investigated in accordance with the standardised guidelines OECD 115 and EU Method A.5, under GLP conditions using the ring method.
A solution of 1 g/L was prepared. After shaking the majority of the sample sank to the bottom of the glassware. After 20 minutes sonication the sample remained insoluble. A second solution of 1 mg/L was prepared which sank to the bottom of the glassware. After 30 minutes of sonication the sample remained insoluble.
