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:
- 2018-02-16 - 2018-02-18 (experimental phase)
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995
- Deviations:
- no
- Qualifier:
- according to guideline

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Ambient temperature (10 to 30°C), in the dark - Key result
- Surface tension:
- 47.3 mN/m
- Temp.:
- 20.8 °C
- Conc.:
- 150 mg/L
- Remarks on result:
- other: pH = 6.5
- Surface tension:
- >= 47 - <= 48.5 mN/m
- Temp.:
- 20.8 °C
- Conc.:
- 150 mg/L
- Remarks on result:
- other: pH = 6.5
- Conclusions:
- The surface tension was determined in a GLP guideline study according to OECD 115 and EU method A.5 without deviations on the registered substance itself. Hence, there is no indication given that the results are not reliable. The mean surface tension of duplicate 90% saturated solutions of test item in water has been determined to be 47.3 mN/m at 20.8 ± 0.5 °C. According to criteria stated in EC Method A.5, substances showing a surface tension lower than 60 mN/m under the conditions of this method should be regarded as being surface-active.
- Executive summary:
The mean surface tension of duplicate 90% saturated solutions of Amines, C12-14-tert-alkyl, reaction products with O,O-di-C1-C14-alkyl hydrogen phosphorodithioate in water has been determined to be 47.3 mN/m at 20.8 ± 0.5 °C, using a ring method, designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995, under GLP. The test item was considered to be surface-active.
