Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: 52834
- Expiration date of the lot/batch: 8 Nov 2004
- Purity: 99.08%
- Storage condition: Room temperature in the dark
Key result
Surface tension:
70 mN/m
Temp.:
20 °C
Conc.:
1 000 mg/L
Conclusions:
The surface tension of a 1 g/l solution of test item was found to be 70.0 mN/m. As a result is greater than 60 mN/m, test item is not considered to be surface active

Description of key information

The surface tension of a 1 g/l solution of test item was found to be 70.0 mN/m. As a result is greater than 60mN/m, test item is not considered to be surface active.

Key value for chemical safety assessment

Surface tension:
70
in mN/m at 20°C and concentration in mg/L:
1 000
