Table: Surface tension measurements

Measurement	Time passed after transfer test solution to test vessel [minutes]	Surface tension (mN/m)
		individual	mean (1)	mean multiplied by Φband Harkins-Jordan corrected value
1	20	64.8	65.2	65.4
2	21	65.0
3	22	65.1
4	23	65.3

(1)Mean calculated from measurements 2 to 6, after equilibrium was reached.

Conclusions:

The surface tension of an aqueous substance solution at 1 g/L was determined to be 65.4 mN/m (at 20°C).

Executive summary:

Using the OECD harmonized ring method in a GLP study according to EC A.5 and OECD 115, the surface tension of an aqueous substance solution at 1 g/L was determined to be 65.4 mN/m (at 20°C). According to the EC A.5 guideline the substance is not surface active.

Description of key information
