Description of key information

OECD Guideline 115, EU Method A5, GLP, key study, validity 1:
Surfate tension = 32.7 mN/m at 20.2°C (the substance is considered as surface active).

Key value for chemical safety assessment

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

Additional information

Experimental and litterature data are available to determine the surface tension of TBEP.

According to the key study, performed according to OECD Guideline 115 and EU Method A5 with GLP statement, the surface tension of TBEP was determined to 32.7 mN/m at 20.2°C ± 0.1°C. By comparison to the criteria from the EU Method A.5, the substance has to be considered as a surface active substance.
