Applicant's summary and conclusion

Conclusions:
The pH of a 1% w/v dispersion of OS2200 is 6.3.
Executive summary:

The test was performed according to CIPAC MT 75.3 Method (OECD Guideline 122). The pH was measured with a pH-meter (Model 250 Ion Analyser, Corning). The pH of a 1% w/v dispersion of OS2200 at 20ºC was found to be 6.3.
