Description of key information

Key result for CAS# 297730-93-9:
Surface tension of a solution at 90% of saturation: 71.6 mN/m at 20 °C (OECD TG115). CAS# 297730-93-9 is not a surfactant.

Key value for chemical safety assessment

Additional information

Discussion for CAS# 297730-93-9:

The surface tension test of an aqueous solution of CAS# 297730-93-9 was determined using a method based on OECD TG115 and EEC Directive 92/69 EEC, A.5.  The study is classified as acceptable and satisfies the guideline requirements for surface tension tests.  Further, CAS# 297730-93-9 is extremely insoluble in water, extremely volatile from aqueous solution, and is unlikely to remain in dissolved form in open systems.  Therefore, CAS# 297730-93-9 does not have surfactant properties.
