Additional information

According to Annex VII of the REACH Regulation 1907/2007, Column 2, the study needs only to be conducted if:

- based on structure, surface activity is expected or can be predicted; or

- surface activity is a desired property of the material.

No surface activity for the substance is expected, therefore the test has not been conducted.
