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 March to 3 April 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- Key result
- Surface tension:
- 71.75 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: Nominal saturated solution
- Conclusions:
- The surface tension value was found to be 71.75 mN/m at 20.1°C ± 0.1°C. CAS 577978-76-8 is classified as not being a surface active substance.
- Executive summary:
The surface tension determination was conducted to GLP according to the OECD 115 test guideline. The test item was assessed at a maximal feasible concentration of soluble fractions (according to the allowed maximum in the guidelines), was carried out by a Krüss K11 Tensiometer using the ring method. The surface tension value was found to be 71.75 mN/m with 0.50 RSD% at 20.1°C ± 0.1°C (at 1 g/L as nominal saturation level with unknown actual dissolved amount).
As the surface tension value of the quasi-saturated aqueous solution of the test item was greater than 60 mN/m under the conditions of this test, CAS 577978-76-8 is classified as not being a surface active substance.
