Note 128 — FOREWORD (continued 8)

The E. L. Patch Company declares that “no hexa­methylen­amine has ever been used in the manufacture of Formitol tablets,” and that ammonium chloride and para­form­aldehyde are among the ingredients used in the manufacture of these tablets. The hexa­methylen­amine present in the tablets, therefore, must have been produced by interaction of the para­form­aldehyde and ammonium chloride. This does not alter the laboratory findings regarding the composition of the tablets, namely, that they “contain formaldehyde (or para­form­aldehyde), an ammonium compound and some hexa­methylen­amine.”
