- Expiration date of the lot/batch: 14 September 2019
Key result
Surface tension:
29 mN/m
Temp.:
20 °C
Conc.:
1 g/L

The surface tension of a 1 g/L aqueous dispersion in water was found to be 29.0 mN/m at 20°C.

As the result was less than 60 mN/m, the test item was considered to be surface active.

Conclusions:
The surface tension of a 1 g/L aqueous dispersion in water was found to be 29.0 mN/m at 20°C.
As the result was less than 60 mN/m, the test item was considered to be surface active.

Description of key information

The surface tension of a 1 g/L aqueous dispersion of the test item in water was found to be 29.0 mN/m at 20°C.

As the result was less than 60 mN/m, the test item was considered to be surface active.

Key value for chemical safety assessment

Surface tension:
29
in mN/m at 20°C and concentration in mg/L:
