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:
- Experimental dates: 15-18 October 2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. The substance is adequately characterised. Therefore full validation applies.
- Reason / purpose for cross-reference:
- reference to other study

- Version / remarks:
- July 27, 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- Commission Regulation (EC) No 440/2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: ISO 304 – Surface Active Agents – Determination of surface tension by drawing up liquid films
- Version / remarks:
- 1985-12-15
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- signed on 15 Nov. 2018
- Type of method:
- OECD harmonised ring method
- Specific details on test material used for the study:
- Storage conditions: Ambient temperature away from light. Kept in the original container.
- Key result
- Surface tension:
- 50.6 mN/m
- Temp.:
- 20.4 °C
- Conc.:
- 45.3 mg/L
- Remarks on result:
- other: expected 90% of saturation
- Conclusions:
- According to EU A5 criteria, as the result is below the threshold value of 60 mN/m, the substance is considered to have surface-active potential under the experimental conditions.
- Executive summary:
The surface tension of the test substance was measured under GLP according to OECD 115/EU A5 guidelines, using the ring method.
The apparatus was calibrated with a mass.
Two determinations were performed, on two indepenent solutions prepared by diluting saturated solutions to 90%. Actual concentrations were not checked. Their surface tension was then determined from five consecutive consistent measurements. The final result was the mean of two consistent determinations.
The surface tension of the test solution (ca 45.3 mg/L) at 20.4°C was 50.6 mN/m.
Reference
Measurements on reference substances complied with the validation criteria.
First Determination
Mean of 5 stable values = 50.8 mN/m
Temperature: 20.6 - 20.5°C
Second Determination
Mean of 5 stable values = 50.5 mN/m
Temperature: 20.5 - 20.3°C
As the mean surface tensions obtained with trials 1 and 2 do not differ by more than 0.5 mN/m, no additional trial is needed.
The mean value of 50.6 mN/m is retained for final result.
Description of key information
According to EU A5 criteria, as the result is below the threshold value of 60 mN/m, the substance is considered to have surface-active potential under the experimental conditions. However, since the structure is not characteristic of a true surfactant, and it is not the intended use of the substance (i.e. not a desired property), this conclusion should be taken with caution.
Key value for chemical safety assessment
- Surface tension:
- 50.6
- in mN/m at 20°C and concentration in mg/L:
- 45.3
Additional information
Based on the chemical structure, showing no alert, and considering the substance is not intended to be used as a surfactant, no further data should be required.
However, 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 actual concentration was not checked, but calculated as 90% expected of the water solubility.
