Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1982
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: EEC Directive 79/831, 3.5
- Deviations:
- yes
- Remarks:
- - the rings are heated on a Bunsen burner with city gas instead of a methanol flame
- GLP compliance:
- yes
- Type of method:
- ring method
- Surface tension:
- 60 mN/m
- Temp.:
- 20 °C
- Conc.:
- 10 g/L
- Remarks on result:
- other: Mean values of 5 measurements
- Conclusions:
- The surface tension of test substance was determined to be 60.0 mN/m at 20°C, filtrates of a 1g/100mL slurry
Reference
The test substance is only very slightly soluble in water.The solution measured in this experiment is thus the filtrate of a 1g/100mL slurry of test substance.
Description of key information
The study provided was conducted to recognised testing guidelines and with GLP certification.
Key value for chemical safety assessment
- Surface tension:
- 60
- in mN/m at 20°C and concentration in mg/L:
- 10 000
Additional information
Based on the criteria as outlined in the OECD Guideline it is concluded that the test substance should not be regarded as being surface-active material.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
