- Key result
- Surface tension:
- 66.6 mN/m
- Temp.:
- 20 °C
- Remarks on result:
- other: concentration was not numerically quantified but saturated aqueous solution was used
- Conclusions:
- From the experimental data obtained, it can be concluded that the surface tension of the test article is 35.8 mN/m at 20 °C and 33.4 mN/m at 40 °C and 66.6 mN/m at 20 °C for the aqueous saturated solution.
According to the data obtained for the saturated aqueous solution, the sample of d-phenothrin technical grade should be regarded as a non surface-active material, following the interpretation of the results reported in point 3.2 of the OJEC A.5 method.

Description of key information
The surface tension of the test article is 35.8 mN/m at 20 °C and 33.4 mN/m at 40 °C and 66.6 mN/m at 20 °C for the saturated aqueous solution. Thus, the substance is considered non-surface active.
Key value for chemical safety assessment
- Surface tension:
- 66.6
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
