Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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:
- 27 May 2010-15 July 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- This study has been performed according to OECD and EC guidelines and according to GLP principles. Test substance is adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- 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:
- 73.6 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 a solution of aluminium chloride basic (content ca 36%, as typically manufactured) was investigated according to OECD/EC guidelines, ring method. The mean of five consecutive consistent measurements, at the maximum testing concentration of 1 g solution/L in double-distilled water and 20°C, was corrected for calibration factor and according to Harkins-Jordan table. The final retained result is 73.6 mN/m.
Reference
The calibration factor was calculated to be 1.01.
The mean of five consistent measurement was 72.9 mN/m (before correction).
Description of key information
Aluminium chloride basic (aqueous solution as manufactured) is NOT considered to be surface-active.
Key value for chemical safety assessment
- Surface tension:
- 73.6
- 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. It should be
noted that the test concentration refers to the substance as manufactured, i.e. 1 g/L of solution, not of salt.
Furthermore, inorganic substances are generally known to have no impact or slightly increase the surface tension of water.
As an UVCB, it should be noted that the value of the parameter may show some variations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
