Applicant's summary and conclusion

Executive summary:

In a study similar to CIPAC MT 75 following pH values were determined for aqueous solutions:

pH 10.8 at a concentration of 0.1 % (w/w as hydrate)

pH 11.5 at a concentration of 1.0 % (w/w as hydrate)

pH 12.3 at a concentration of 10 % (w/w as hydrate)
