Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP study according to method 115 of the OECD guidelines
Qualifier:
equivalent or similar to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Principles of method if other than guideline:
test temperature 21.5 +-0.5°C
GLP compliance:
yes
Type of method:
ring method
Surface tension:
72.3 mN/m
Temp.:
21.5 °C
Conc.:
1.01 g/L
Remarks on result:
other: temperature precision 21.5 +/- 0.5°C
Conclusions:
The surface tension was determined to be 72.3 mN/m for a 1.01g/l solution at 21.5±0.5°C. The substance was also considered not to be a surface-active material.

Description of key information

The surface tension was determined to be 72.3 mN/m for a 1.01 g/L solution at 21.5±0.5°C. The substance was also considered not to be a surface-active material.
The surface tension of pure Epichlorohydrin at 25°C is 0.037 N/m.

Key value for chemical safety assessment

Surface tension:
72.3
in mN/m at 20°C and concentration in mg/L:
