Reference
Individual results:
| Test | Range of values | Measuring period |
| water as reference | 70.8 to 71.2 mN/m | 59 min |
| test substance 1st un | 62.5 to 62.7 mN/m | 71 min |
| test substance 3rd run | 62.4 to 62.8 mN/m | 59 min |
Description of key information
Study conducted to recognised training guidelines with GLP
Key value for chemical safety assessment
- Surface tension:
- 62.6
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The surface tension was determined by ring method to be 62.6 mN/m at 20°C (c= 1 g/L)
Based on the criteria as outlined in the OECD Guideline it is concluded that the test substance should not be regarded as being surface-active material.Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
