- Specific details on test material used for the study:
- Product designation: Monoazo Yellow BG 3247
Identification: FAT 40400/A BG 3247/TV 6 - Surface tension:
- >= 38.9 - <= 43.1 mN/m
- Temp.:
- 20 °C
- Conc.:
- 10 g/L
- Surface tension:
- >= 61.1 - <= 69 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of FAT 40400/A is between 61.1 - 69.0 mN/m at a concentration of 1 g/L and between 38.9 - 43.1 mN/m at a concentration of 10 g/L.
- Executive summary:
In a GLP-compliant study, performed according to EC method A.5, the surface tension of the test substance was determined using the Wilhelmy plate method. The surface tension of an aqueous solution of the test substance at 20 °C is between 61.1 - 69.0 mN/m at a concentration of 1g/L and between 38.9 - 43.1 mN/m at a concentration of 10 g/L.

Description of key information
In a GLP-compliant study, performed according to EC method A.5, the surface tension of the test substance was determined using the Wilhelmy plate method (Ciba-Geigy 1990). The surface tension of an aqueous solution of the test substance at 20 °C is between 61.1 - 69.0 mN/m at a concentration of 1 g/L and between 38.9 - 43.1 mN/m at a concentration of 10 g/L.
