Any other information on results incl. tables

Less than 10% hydrolysis after 5 days at 50°C which equates to a half-life of greater than 1 year at 25°C.

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
Herbanate has been found to undergo less than 10% hydrolysis after 5 days at 50°C in pH 4, 7 and 9 buffer solutions.
The half-life at 25°C has been estimated and is given below:
pH Half-life
4 > 1 year
7 > 1 year
9 > 1 year
