- Specific details on test material used for the study:
- Name: Monoazo Red SR 6947
Purity: 89.3%
Storage: room temperature, 20 - 24 °C - Surface tension:
- >= 66.3 - <= 66.4 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: after 30 minutes
- Surface tension:
- >= 55.1 - <= 55.4 mN/m
- Temp.:
- 20 °C
- Conc.:
- 10 g/L
- Remarks on result:
- other: after 15 minutes
- Conclusions:
- The surface tension of an aqueous solution of the test solution at 20 °C by the Wilhelmy plate method lies between 66.3 - 66.4 mN/m at a concentration of 1 g/L and between 55.1 - 55.4 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 lies between 66.3 - 66.4 mN/m at a concentration of 1 g/L and between 55.1 - 55.4 mN/m at a concentration of 10 g/L.
