Description of key information

Key value for chemical safety assessment

Surface tension:
28.9
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

In the non-GLP Klimisch 1 study from Kintrup (2012) the surface tension of Butanedioic acid, 2(or 3)-sulfo-, 4-[2-[(1-oxo(C12-18(even numbered) and C18unsaturated)alkyl)amino]ethyl]esters, disodium 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 28.9 mN/m.

The result is considered acceptable for the risk assessment.
