Specific details on test material used for the study:
- Storage condition of test material: store at room temperature in thightly closed original container, keep dry.
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.
