Applicant's summary and conclusion

Conclusions:
- surface tension (at 20°C) = 26.2 mN/m
- surface tension (at 25°C) = 25.8 mN/m
Executive summary:

According to Lange`s Handbook of Chemistry, the surface tension of Tributyl borate is:

- 26.2 mN/m at 20°C,

- 25.8 mN/m at 25°C.

According to EU Method A.5, substances showing a surface tension lower than 60 mN/m should be regarded as being surface-active materials. Thus, Tributyl borate is a surface-active substance.
