- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- (of Directive 92/69/EEC)
- Deviations:
- yes
- Remarks:
- Limited reporting detail - missing information on impurity content
- GLP compliance:
- yes
- Type of method:
- ring method
- Surface tension:
- 70.9 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of a 1 g/L solution of platinum(II) tetraammine diacetate was determined to be 70.9 mN/m at 20 deg C. The test substance is not considered to be surface active under the criteria described in the Test Method Regulation (EU 440/2008).
- Executive summary:
In a guideline study, conducted to GLP, the surface tension of a 1 g/L solution of platinum(II) tetraammine diacetate was evaluated by the ring method. The surface tension was determined to be 70.9 mN/m at a temperature of 20 deg C. According to the criteria described in the Test Method Regulation (EU 440/2008, method A.5; a substance is surface active if its surface tension is < 60 mN/m). As such, platinum(II) tetraammine diacetate is not considered to be surface active.

Description of key information
In a guideline study, conducted to GLP, the surface tension of a 1 g/L solution of platinum(II) tetraammine diacetate was evaluated by the ring method. The surface tension was determined to be 70.9 mN/m at a temperature of 20 deg C (Mekelburger, 2006b). According to the criteria described in the Test Method Regulation (EU 440/2008, method A.5; a substance is surface active if its surface tension is < 60 mN/m). As such, platinum(II) tetraammine diacetate is not considered to be surface active.
Key value for chemical safety assessment
- Surface tension:
- 70.9
- in mN/m at 20°C and concentration in mg/L:
- 1 000
