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.

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.
