Results and discussion
Surface tension
- Surface tension:
- 40.12 mN/m
- Temp.:
- 18 °C
- Remarks on result:
- other: no concentration given / 40.12 mN/cm at 18 °C in contact with air.

no concentration given
Applicant's summary and conclusion
- Conclusions:
- the surface tension of DMS is determined to be 40.1 mN/cm at 18°C. Due to the fact that the suface tension is <60 mN/cm, the test item is classified as surface-active substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
