- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Version / remarks:

- yes
- Type of method:
- ring method
- Key result
- Surface tension:
- 70.4 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The determined value of the surface tension of an aqueous solution of methenamine at 20.0 °C was 70,4 mN/m (c = 1.0 g/L, after 40 minutes). Therefore the test substance is classified to be not a surfactant.
- Executive summary:
The determined value of the surface tension of an aqueous solution of methenamine at 20.0 °C was 70,4 mN/m (c = 1.0 g/L, after 40 minutes). Therefore the test substance is classified to be not a surfactant.

Description of key information
The determined value of the surface tension of an aqueous solution ofmethenamineat 20.0 °C was 70.4mN/m (c = 1.0 g/L, after 40 minutes). Therefore no surfactant properties are to be expected and consequently the test substance does not meet the criteria for classification as a surfactant.
Key value for chemical safety assessment
- Surface tension:
- 70.4
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
