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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Endpoint:
- surface tension
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Study period:
- 9/2010
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- GLP study, tested with the source substance Nitroglycerin. According to the ECHA guidance document “Practical guide 6: How to report read-across and categories (March 2010)”, the reliability was changed to RL2 to reflect the fact that this study was conducted on a read-across substance.

- 19.9 °C
- Conc.:
- 1 g/L
Applicant's summary and conclusion
- Conclusions:
- Based on the results from the test, the substance Ethylene Glycol Dinitrate can be classified as a not surface active substance.
- Executive summary:
The surface tension of an aqueous solution ofEthylene Glycol Dinitratewas determined as 72.13 ± 0.06 mN/m at 19.9°C. One measurement was performed for verification (after 61 minutes). No significant changes and thus no significant dependence on time and temperature were observed.
As these values were higher than 60 mN/mEthylene Glycol Dinitrate was classified as not surface active.
The surface tension of the negative control lay within the accepted range.
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).
