Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2011
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline compliant well documented non-GLP study.
Qualifier:
according to guideline
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
no
GLP compliance:
no
Type of method:
ring method
Surface tension:
44.1 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Conclusions:
Surface tension: 44.1 mN/m
Executive summary:

In the non-GLP Klimisch 1 study from Kintrup (2013) the surface tension of Aspartic acid, N-(3-carboxy-1-oxo-sulfopropyl)-N-(C16-18 (even numbered), C18 unsaturated alkyl) tetrasodium salts was determined according to test method EEC A.5 with the ring method at 20 °C and a concentration of 1 g/L to be 44.1 mN/m.

The result is considered acceptable for the risk assessment.
