- Conclusions:
- The surface tension of an aqueous preparation of the test item (ß = 1 g/I) at 20°C was found to be at 62.6 mN/m.
- Executive summary:
In this guideline (OECD 115) study conducted to GLP standards, the test material (EC 231-272-0) was determined to have s surface tension of 62.6 mN/m at 20°C
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. 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).
