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:
- 28 May 2010- 5 August 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:

- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- OECD harmonised ring method
- Key result
- Surface tension:
- 75.3 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- In the experimental conditions, the test substance is NOT considered to be surface active.
- Executive summary:
The surface tension of diluminium chloride pentahydroxide was measured according to OECD 115/EU A5 guidelines, ring method.
The mean of five consecutive consistent measurements, at the maximum testing concentration of 1 g/L in double-distilled water and 20°C, was corrected with calibration factor from water and according to Harkins-Jordan table.
The final retained result is 75.3 mN/m.
Reference
The water calibration factor was calculated to be 1.03.
The mean of five consistent measurements was 73.1 mN/m (before correction).
Description of key information
Dialuminium chloride pentahydroxide is NOT considered as surface-active.
Key value for chemical safety assessment
- Surface tension:
- 75.3
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Therefore, it is considered as a key study, and the result is retained as key data.
Furthermore, inorganic substances are generally known to have no impact or slightly increase the surface tension of water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
