- Conclusions:
- The surface tension of a 90% saturated solution of Hatcol 3331 in water is 72.6 mN/m.
- Executive summary:
The determination of the surface tension of an aqueous solution of HATCOL 3331 was based on EEC-Directive 92/69 EEC, A.5 "Surface tension" (1992) and OECD guideline no. 115: "Surface tension of aqueous solutions", July 27, 1995.
