Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Version / remarks:
ring method according DIN EN 14370
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
no
GLP compliance:
no
Type of method:
ring method
Surface tension:
28.8 mN/m
Temp.:
20.3 °C
Conc.:
1 g/L
Conclusions:
The surface tension of Reaction product of lauryl-PDA/lauryl-DETA with chloroacetic acid was determined to be 28.8 ± 0.04 mN/m at 20°C.
Executive summary:

The surface tension of Reaction product of lauryl-PDA/lauryl-DETA with chloroacetic acid was determined according to OECD Guideline 115 and EU method A.5 using the ring method. Double distilled water and 1-Octanol have been measured as calibration and control sample.

The surface tension of the test item was determined to be 28.8 ± 0.04 mN/m at 20°C. As the surface tension is lower than 60 mN/m, the test item is surface-active.

Description of key information

28.8 ± 0.04 mN/m at 20°C and 1 g/L (OECD Guideline 115/ EU method A.5; ring method; RL1)

Key value for chemical safety assessment

Surface tension:
28.8
in mN/m at 20°C and concentration in mg/L:
