Test material
- Reference substance name:
- Phenyl bis(2,4,6-trimethylbenzoyl)-phosphine oxide
- EC Number:
- 423-340-5
- EC Name:
- Phenyl bis(2,4,6-trimethylbenzoyl)-phosphine oxide
- Cas Number:
- 162881-26-7
- Molecular formula:
- C26H27O3P
- IUPAC Name:
- [phenyl(2,4,6-trimethylbenzoyl)phosphoryl](2,4,6-trimethylphenyl)methanone

Results and discussion
Surface tension
- Surface tension:
- ca. 71.1 mN/m
- Temp.:
- 20 °C
- Remarks on result:
- other: The test was conducted with a saturated solution
Applicant's summary and conclusion
- Conclusions:
- The test substance is not expected to be surface atvive. By definition, a chemical has surface activity when the surface tension is less than 60 nM/m.
