Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 200-316-0 | CAS number: 57-14-7
Surface tension
Administrative data
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Secondary citation, but by peer-reviewed and recognized source. The test could have been exempted according to Annex VII in absence of prevision of tensio-activity and because this is not a wished property of the substance.
