key study
Study period:
17 Dec 2018 to 25 Jan 2019
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.5 (Surface Tension)
Version / remarks:
March 04, 2016
Deviations:
no
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Version / remarks:
July 27, 1995
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
OECD harmonised ring method
Specific details on test material used for the study:
Physical Description: Off-white powder (determined by Charles River Den Bosch)
Purity/Composition: 99.77%, assumed 100% for testing
Storage Conditions: At room temperature protected from light desiccated
Key result
Surface tension:
70.62 mN/m
Temp.:
20 °C
Conc.:
90 vol%
Conclusions:
The OECD harmonized ring method was applied for the determination of the surface tension of Esacure 1001 M.

The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 70.62 mN/m. According to this, the test item is considered not to be surface active.
Executive summary:

In this guideline (OECD 115) study, conducted with GLP certification, the test item EC 429-040-0 was determined to have a surface tension of 70.52 mN/m @ 20 °C at a concentration of 90% test item saturation solubility in water.

Description of key information

Study conducted to recognised testing guidelines with GLP certification.

Key value for chemical safety assessment

Surface tension:
70.62

Additional information

Study performed with test solution at 90% of the test item saturation solubility in water.
