Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 20 March 1997
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Guideline study, to GLP.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:
- (of Directive 92/69/EEC)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- ring method
- Surface tension:
- 71.1 mN/m
- Temp.:
- 20.3 °C
- Conc.:
- 1 g/L
- Remarks on result:
- other: The test substance was regarded to be not surface active.
- Conclusions:
- The surface tension of a 1 g/L solution of tetraammineplatinum(II) hydrogen carbonate was determined to be 71.1 mN/m at 20.3 deg C, and is therefore considered not to be surface active.
- Executive summary:
In a guideline study, conducted to GLP, the surface tension of a 1 g/L solution of tetraammineplatinum(II) hydrogen carbonate was evaluated by the ring method. The surface tension was determined to be 71.1 mN/m at a temperature of 20.3 deg C. Tetraammineplatinum(II) hydrogen carbonate is considered not to be surface active.

Description of key information
The surface tension of a 1 g/L solution of tetraammineplatinum(II) hydrogen carbonate was determined to be 71.1 mN/m at 20.3 deg C. Tetraammineplatinum(II) hydrogen carbonate is considered not to be surface active (Holldorf, 1997).
Key value for chemical safety assessment
- Surface tension:
- 71.1
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
