- Key result
- Surface tension:
- 48.1 mN/m
- Temp.:
- 21.5 °C
- Conc.:
- 90 other: % saturation
- Remarks on result:
- other: pH 3.5
- Conclusions:
- The surface tension of solutions prepared at nominally 1.1 g/L of test item in water and diluted to 90 % saturation was determined to be 48.1 mN/m at 21.5 ± 0.5 °C and the substance was considered to be surface-active.
- Executive summary:
GUIDLELINE
The determination was carried out by a ring method, using a procedure designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for the Testing of Chemicals, 27 July 1995.
RESULTS
The surface tension of solutions prepared at nominally 1.1 g/L of test item in water and diluted to 90 % saturation was determined to be 48.1 mN/m at 21.5 ± 0.5 °C and the substance was considered to be surface-active.
- Endpoint:
- surface tension
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:

Description of key information
The surface tension of analogue test item solutions prepared at nominally 1.1 g/L in water and diluted to 90 % saturation was determined to be 48.1 mN/m at 21.5 ± 0.5 °C and the substance was considered to be surface-active (OECD 115 and EU Method A.5).
Key value for chemical safety assessment
- Surface tension:
- 48.1
- in mN/m at 20°C and concentration in mg/L:
- 990
