- Key result
- Surface tension:
- 32.9 mN/m
- Temp.:
- 20.1 °C
- Conc.:
- 1 g/L
- Conclusions:
- The mean surface tension of the test item diluted at 1 g/L in distilled water at 20.1°C was 32.9 mN/m. The test item was considered as surface-active in the experimental conditions used.
- Executive summary:
The surface active properties of the test item were investigated in a GLP-compliant study performed in accordance with EU Method A.5 (Surface Tension) and OECD Guideline 115 (Surface Tension of Aqueous Solutions). The mean surface tension of the test item diluted at 1 g/L in distilled water at 20.1°C was 32.9 mN/m. The test item was considered as surface-active in the experimental conditions used.

Description of key information
The surface active properties of the test item were investigated in a GLP-compliant study (Demangel, 2019) performed in accordance with EU Method A.5 (Surface Tension) and OECD Guideline 115 (Surface Tension of Aqueous Solutions). The mean surface tension of the test item diluted at 1 g/L in distilled water at 20.1°C was 32.9 mN/m. The test item was considered as surface-active in the experimental conditions used.
Key value for chemical safety assessment
- Surface tension:
- 32.9
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The surface active properties of the test item were investigated in a GLP-compliant study (Demangel, 2019) performed in accordance with standard methods, without deviations. The study is considered as reliable without restriction (Klimisch 1) and was selected as key study for the endpoint.
