- 4.167 other: mg/l (90% saturated aqueous solution of test item)
Applicant's summary and conclusion
- Conclusions:
- In this test conditions, the surface tension of a 90% saturated aqueous solution of the test item CETONAL at 20°C was determined to be 53.01 mN/m (standard deviation +/- 0.04 mN/m).
Due to the fact the surface tension is < 60 mN/m, the test item is classified as surface active substance. - Executive summary:
The surface tension of an aqueous solution with a concentration of 90% saturated concentration of CETONAL was determined according to the OECD Guideline 115.
The determination was carried out with a tensiometer in the ten sucessive measurements with a standard deviation <= 0.05 mN/m at a temperature of 20 +/- 0.5°C.
The surface tension of a 90% saturated aqueous solution of the test item CETONAL at 20°C was determined to be 53.01 mN/m (standard deviation +/- 0.04 mN/m).
Due to the fact the surface tension is < 60 mN/m, the test item is classified as surface active substance.
