Applicant's summary and conclusion

Conclusions:
Substance has a high pH, typical of materials regarded as corrosive.
Executive summary:

The pH of the substance depends on the process that produces it and is primarily determined by the residual amounts of strong alkali impurities remaining in the stream rather than the intrinsic pH of the main components that make up this multi-constituent substance.
