Key result

Surface tension:

71 mN/m

Temp.:

20 °C

Conc.:

1 g/L

Only one measurement performed since surface tension was greater than 60 mN/m

Conclusions:

The surface tension of a 1 g/L aqueous solution of the test item was measured to be 71 mN/m at 20 oC.

Executive summary:

The surface tension of a 1 g/L aqueous solution of the test item was measured to be 71 mN/m at 20 ^oC.

Endpoint:

surface tension

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because surface activity is not a desired property of the material

Description of key information

The surface tension of a 1 g/L aqueous solution of the test item was measured to be 71 mN/m at 20 ^oC. This is not a required measurement as surface activity is not a desired property of the sodium formate.

Key value for chemical safety assessment

Surface tension:

71

in mN/m at 20°C and concentration in mg/L:
