Description of key information

Experimental value of surface tension at 20°C for test itel solution at 1g/l: 38.5mN/m

Key value for chemical safety assessment

Surface tension:
38.5
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

The surface tension was determined using the ring method according to Method A.5 "Surface Tension" of Commission Regulation N°440/2008 of 30 May 2008, Method 115 "Surface Tension of aqueous solution" of OECD Guidelines and GLP. No deviation from the guidelines was observed.

The mean surface tension of the test item at 1 g/L in demineralized water, is lower than 60 mN/m, so the test item is considered to be surface active in the experimental conditions used.
