Applicant's summary and conclusion
- Conclusions:
- The pH of 40 to 62 % aqueous solution measured at 20 °C is 12-13.
- Executive summary:
The empirical data of the pH according to DIN EN 1262 for the 40 to 62 % solution, measured at 20 °C, show that the pH is 12-13. Thus, the solution of sodium N-methyltaurinate is an alkaline liquid.
