Applicant's summary and conclusion

Conclusions:
As the values has been determined by an guideline study it can be considered as reliable.
Executive summary:

According to the results of the examination the dried films of the coating formulation show migration of benzoguanamine with aqueous food simulants and fat simultan (50% Ethanol).
