Results and discussion

pH value
pH value:
> 7.1 - < 7.3
Temp.:
20 °C
Concentration:
>= 10 mg/L

Any other information on results incl. tables

No details on the method have been noted. However, the solution was meassured with a pH-meter several times. The solution of 10 mg/l corresonds approximatelyx to the water solubility.

Applicant's summary and conclusion

Conclusions:
A satureated solution of TGMDA (10 mg/l) has a pH-value of approximately 7.1-7.3.
Executive summary:

The pH-value of a more or less saturated solution of TGMDA has been determined to be 7.1 -7.3
