Applicant's summary and conclusion

Conclusions:
Any solution of cyanamide manufactured at AlzChem Trostberg GmbH is stabilised at pH 4.5 with phosphoric acid.
Executive summary:

Any solution of cyanamide manufactured at AlzChem Trostberg GmbH is stabilised at pH 4.5 with phosphoric acid.


Based on that for studies preapred with cyanamide in water a pH of the solution of 4.5 has to be noted. This is true for "Cyanamid L500"; "Alzogur"; "Dormex" and all other liquide mixtures that are based on Cyanamide in water.
