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:
- The study was conducted between 21 December 2017 and 24 March 2018.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The study is considered to be a reliability 1 as it has been conducted according to OECD 115 using the ring method and in compliance with GLP.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- GLP compliance:
- yes
- Type of method:
- ring method
- Specific details on test material used for the study:
- Identification: FRET 15-0735
Appearance/Physical state: Clear colorless liquid
Storage conditions: Room temperature, in the dark - Surface tension:
- 44.8 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: Sample 1
- Surface tension:
- 44.9 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: Sample 2
- Conclusions:
- The Surface Tension of FRET 15-0735 has been determined to be 44.9 mN/m at 20.0 ± 0.5 °C according to OECD TG 115 (Surface Tension of Aqueous Solutions) using the ring method in compliance with GLP. According to EU method A5, the substance is considered to besurface active because the value is less than 60mN/m.
- Executive summary:
The Surface Tension of FRET 15-0735 has been determined to be 44.9 mN/m at 20.0 ± 0.5 °C according to OECD TG 115 (Surface Tension of Aqueous Solutions) using the ring method. According to EU method A5, the substance is considered to besurface active because the value is less than 60mN/m.
