Materials and methods

Test guideline

Test guideline 1

Qualifier:

according to guideline

Guideline:

EU Method A.5 (Surface Tension)

Deviations:

no

Test guideline 2

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Guideline 115 (Surface Tension of Aqueous Solutions)

Deviations:

yes

Test guideline 3

Qualifier:

according to guideline

Guideline:

other: IS0 304 ("Surface active agents - Determination of Surface Tension by Drawing up Liquid Films")

Deviations:

no

Principles of method if other than guideline:

As an alternative to the ring method, which is primarily suggested by the test guideline, we prefer to use the Wilhelmy plate method because it allows a better assessment of the time dependence of the surface tension, if present. Appendix I of the original study report shows a comparison of the surface tension values of four calibrating liquids, measured with the hereby used Wilhelmy plate, with reference values from the OECD TG No. 115 and the IS0 norm. As can be seen, the difference between measured and reference values is in all cases less than 0.2m/m.

GLP compliance:

yes

Type of method:

plate method

Applicant's summary and conclusion

Conclusions:

The surface tension of aqueous solutions of test substance CA 2343 is: σ = 72.8 mN/m (solutions of 1 g/l).

Executive summary:

The purpose of this study was to determine the surface tension of aqueous solutionsof test item CA2343 (oxadiazinamine). The surface tension of test substance CA 2343 is: σ = 72.8 mN/m (solutions of 1 g/l). The study was performed in accordance with the EEC TG A.5 and IS0 304. As an alternative to the ring method, which is primarily suggested by the test guideline, the use of the Wilhelmv plate method was preferred because it allows a better assessment of the time dependence of the surface tension, if present. The surface tension of aqueous solutions of test substance CA 2343 is: σ = 72.8 mN/m (solutions of 1 g/l).
