Additional information

The surface tension of DOPA-Glycinate (20% a.i.) was determined according to OECD guideline 115 (1995) and EU method A.5 (1992) using the ring method. The surface tension of 0.2008 g a.i./L DOPA-Glycinate was 27.2 mN/m at 20°C; it is considered to be a surface active material.
