- Surface tension:
- 41.21 mN/m
- Temp.:
- 20.1 °C
- Conc.:
- 90 other: % saturated aqueous solution
- Remarks on result:
- other: standard deviation of <0.01mN/m
- Conclusions:
- The surface tension of a 90 % saturated aqueous solution of Fatty acids, C8-10, zinc salts was determined to be 41.21 mN/m with a standard deviation of <0.02 mN/m at a mean temperature of 20.1 °C. Since the surface tension is lower than 60 mN/m, Fatty acids, C8-10, zinc salts can be regarded as surface-active substance according to Council Regulation (EC) No. 440/2008 Method A.5.

Description of key information
The surface tension of a 90 % saturated aqueous solution of Fatty acids, C8-10, zinc salts was determined to be 41.21 mN/m with a standard deviation of <0.02 mN/m at a mean temperature of 20.1 °C. Fatty acids, C8-10, zinc salts can be regarded as surface-active substance.
Key value for chemical safety assessment
- Surface tension:
- 41.21
- in mN/m at 20°C and concentration in mg/L:
- 304.2
Additional information
Fatty acids, C8 -10, zinc salts can be regarded as surface-active substance according to Regulation (EC) No. 440/2008 Method A.5 as the surface tension is lower than 60 mN/m.
Fatty acids, C8 -10, zinc salts has a water solubility of 338.0 mg/L. A 90 % saturated aqueous solution of Fatty acids, C8 -10, zinc salts has therefore a concentration of 304.2 mg/L.
