Specific details on test material used for the study:
Product designation: Monoazo Yellow TZ 2382
Identification: FAT 40224/C
Vers. 10/86 Op. 1/86
Surface tension:
> 68.6 - < 69.8 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Surface tension:
> 44.6 - < 49.8 mN/m
Temp.:
20 °C
Conc.:
10 g/L
Conclusions:
The surface tension of FAT 40224/C is between 68.6 - 69.8 mN/m at 1 g/L solution and between 44.6 - 49.8 mN/m at 10 g/L.
Executive summary:

In a GLP-compliant study with FAT 40224/C, performed according to EC method A.5, the surface tension of the test substance was determined using the Wilhelmy plate method. Based on the study results, the surface tension of an aqueous solution of the test substance at 20 °C is between 68.6 - 69.8 mN/m at 1 g/L solution and between 44.6 - 49.8 mN/m at 10 g/L.
