- Type of method:
- ring method
- Surface tension:
- 66.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension at 20 °C and at a concentration of 1 g/L of test item was determined to be 66.5 mN/m. With this the test item is not regarded as surface active material.
- Executive summary:
According to OECD Test Guideline 115 and Regulation EC No. 440/2008 Part A Method A.5. the surface tension at 20 °C and at a concentration of 1 g/L of test item was determined to be 66.5 mN/m.
According to RegulationEC No. 440/2008 Part A Method A.5. the test item is not regarded as surface active material. The study was conducted in GLP-compliance.
