- yes (incl. QA statement)
- Type of method:
- ring method
- Specific details on test material used for the study:
- Identification: FRET 14-0383
Appearance/physical state: colorless liquid
Storage conditions: approximately 4 °C, in the dark - Key result
- Surface tension:
- 59.1 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: % Saturated solution
- Conclusions:
- The Surface Tension of FRET 14-0383 has been determined to be 59.1 mN/m at 20°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 be/not to be surface active because the value is greater than/less than 60mN/m.
- Executive summary:
The Surface Tension of FRET 14-0383 has been determined to be 59.1 mN/m at according to OECD TG 115 (Surface Tension of Aqueous Solutions) using the ring method. According to EU method A5, the substance is considered to be/not to be surface active because the value is greater than/less than 60 mN/m.
