Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:

- Adequacy of study:
- key study
- Study period:
- FROM 01 SEPTEMBER 2020 TO 21 SEPTEMBER 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Version / remarks:
- 30 May 2008
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- GLP compliance:

- Specific details on test material used for the study:
- Batch: CF-1820A
Purity: >99.00 wt%
Expiry date: 07 February 2027
Storage conditions: Room temperature in the dark - Key result
- Surface tension:
- 72.1 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension at nominally 1 g/L solution of test item in water has been determined to
be 72.1 mN/m at 20 °C. The test item was considered not to be surface-active. - Executive summary:
The determination was carried out using the Ring method, designed to be compatible with Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 (as amended) of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 23 March 2006. The surface tension at a nominally 1 g/L solution Copper Diformate has been determined to be 72.1 mN/m at 20°C. Copper diformate was considered not be surface-active.
Reference
Description of key information
According to criteria stated in EC Method A.5, substances showing a surface tension lower than 60 mN/m under the conditions of this method should be regarded as being surface active.
Key value for chemical safety assessment
- Surface tension:
- 72.1
- in mN/m at 20°C and concentration in mg/L:
- 72.1
Additional information
The surface tension at nominally 1 g/L solution of test item in water has been determined to be 72.1 mN/m at 20 °C. The test item was considered not to be surface-active.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
