Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted
- the study does not need to be conducted because surface activity is not a desired property of the material
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
According to REACh Annex VII / column 2, the study needs only to be conducted if based on structure, surface activity is expected or can be predicted.
The present substance is not intended to be used as a surfactant (i.e. not a desired property), and it does not contain typical groups (such as distinct polar and non-polar parts) indicating that it will have significant surface active properties in solution. Therefore, the study is deemed unnecessary. - Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- experimental dates: 16-19 October 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method with no deviation, and under GLP. The substance is considered to be adequately characterised, with isomers composition. Therefore full validation applies.
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- July 27, 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- Commission Regulation 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 of test material: Stored refrigerated (2-8°C) in aluminium bottle. An injection of nitrogen conditions gas is performed into the bottle after each sampling to keep the test item under nitrogen atmosphere during the storage period.
- Key result
- Surface tension:
- 55.4 mN/m
- Temp.:
- 20.5 °C
- Conc.:
- 36 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.
Three determinations were performed, on three 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 36 mg/L) at 20.5°C was 55.4 mN/m.
Referenceopen allclose all
Measurements on reference substances complied with the validation criteria.
First Determination
Mean of 5 stable values = 56.6 mN/m
Temperature: 20.6 - 20.4°C
Second Determination
Mean of 5 stable values = 55.2 mN/m
Temperature: 20.4 - 20.5°C
As the mean surface tensions obtained with trials 1 and 2 differ by more than 0.5 mN/m, a new trial is performed.
Third Determination
Mean of 5 stable values = 55.5 mN/m
Temperature: 20.5°C
Results of determinations 2 and 3 do not differ by more than 0.5 mN/m, so the mean value of 55.4 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:
- 55.4
- in mN/m at 20°C and concentration in mg/L:
- 36
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.
