Applicant's summary and conclusion

Conclusions:
The pH of 1% w/v aqueous dispersion was measured with the help of pH meter and it was observed to be 4.59 at 28.3 °C.
Executive summary:

The pH determination of test item Di aluminium tris [2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl)benzoate] (CAS No. 15876-39-8) was done following OECD guideline 122. pH of 1 % w/v aqueous dispersion was measured with the help of pH meter and it was observed to be  4.59 at temperature 28.3 °C.

From the obtained value it confirmed that the 1% w/v aqueous dispersion of Di aluminium tris [2-(2,4,5,7-tetrabromo-6-oxido-3-oxoxanthen-9-yl) benzoate] was considered to be acidic in nature.
