Surface Tension Results
The surface tension of W-1108 was measured as an aqueous solution (164.3 mg W-1108 in 15 mL water), according to OECD Test Guideline 80/17.
The result was at 21.1 °C:
36.2 (36.1 - 36.3) mN/m
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
