Applicant's summary and conclusion

Conclusions:
A 43.6% solution of 2-Butyne-1,4-diol, reaction products with 1,2-oxathiolane 2,2-dioxide and sodium hydroxide in water has a pH value of 12.2. Information was gathered scientifically reasonable, and it can be concluded that the solution exhibits corrosive effects.
Executive summary:

The pH of a 43.6% solution of 2-Butyne-1,4-diol, reaction products with 1,2-oxathiolane 2,2-dioxide and sodium hydroxide in water was determined as 12.2 using a pH meter.
