CAS number: -
The corrected surface tension of MV 31 is 71.4 mN/m for a 90% saturated aqueous solution at 19 °C. MV 31 is not considered a surface active material.
The surface tension test of an aqueous solution of MV 31 was determined
according to OECD TG 115 (Harmonized Ring Method) and EC no. 92/69/EEC,
Part A.5: "Surface Tension". Three surface tension measurements were
made at 19 °C every 2 minutes between 2-6 minutes to show equilibration.
The arithmetic mean of the equilibrated values was calibrated against a
water standard and corrected using Harkins-Jordan values. This study is
compliant with GLP standards. Therefore this study is classified as
reliable without restriction.
