Applicant's summary and conclusion
- Conclusions:
- The OECD harmonized ring method was applied for the determination of the surface tension of
b-NADP, Disodium salt.
The surface tension of a test solution at a concentration of 1 g/l in water and at 20°C was 73.2 mN/m.
According to this, the test substance is considered not to be surface active. - Executive summary:
The surface tension of the test substance was determined using the OECD harmonized ring method.
A test solution of the test substance was prepared in double distilled water at a concentration of 1 g/l.Five measurements
were performed until a constant value on the surface tension was reached (< 0.5 mN/m). The time passed since the solution was transferred to the measurement vessel was measured for each measurement.
The test was performed at 20.0 ± 0.5°C.
A test substance with a surface tension < 60 mN/m will be regarded as being a surface active material.
The surface tension of a test solution at a concentration of 1 g/l in water and at 20°C was 73.2 mN/m.
According to this, the test substance is considered not to be surface active.
