Applicant's summary and conclusion
- Conclusions:
- Considering that the surface tension of the test substance was determined to be 58.3 mN/m, under the conditions of a method similar to OECD 115 guideline (ring method), the test substance can be regarded as being a surface active material.
- Executive summary:
The surface tension of the test material has been determined according to OECD test guideline 115. Using the ring method, it was determined that the surface tension of the test material is 58.3 mN/m at 20 °C for a concentration of 1 g/L. Therefore, the substance is regarded as surface-active.
