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:
- March to April 2010
- 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:
- no
- Type of method:
- plate method
- Surface tension:
- 30.65 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Executive summary:
The surface tension was determined with the plate method according to EC A.5 and OECD 115. The surface tension of a 1g/L solution of Docusate Sodium was 30.65 +/- 0.1 mN·m-1.
The result is considered relevant and reliable for the further risk assessment.
Reference
The Single results were :
30.8103 mN/m,
31.0054 mN/m and
31.0786 mN/m
The mean value was 30.96 mN/m
Correction factor: 0.9899
Final result: 30.65 +/- 0.1 mN·m-1
Description of key information
30.65 mN/m
Key value for chemical safety assessment
- Surface tension:
- 30.65
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
In the Klimisch 1 key study (Holzschuh 2010) the surface tension was determined with the plate method according to EC A.5 and OECD 115. The surface tension of a 1g/L solution of Docusate Sodium was 30.65 +/- 0.1 mN·m-1.
The result is considered relevant and reliable for the further risk assessment.
