Applicant's summary and conclusion

Conclusions:
The surface tension of Reactive Orange F08-0314 aqueous solution read on the instrument was 71.8 mN/m at 20°C, using the OECD harmonised ring method, representing the mean of five separate measurements.
Executive summary:

This study has been performed in accordance with the study plan,Directive of the European Communities: Methods for the Determination of Physico-Chemical Properties (A5),Guidelines for Testing of Chemicals of the Organization for Economic Co-operation and Development (OECD Guideline No. 115), and the Principles of Good Laboratory Practice (GLP) and reported with a valid GLP certificate.

 

The determination of the surface tension was carried out on the test item as supplied by the sponsor, with a Krüss K6 Tensiometer using the OECD harmonised ring method. Thevalue was found to be 71.9 mN/m.

As the surface tension value was higher than 60 mN/m, Reactive Orange F08-0314 is not classified as surface active.
