Abstract: Compositions comprising a polyamidopolyamine and/or a non-poly-meric amidoamine are disclosed for imparting multiple desired characteristics to a variety of industrial compositions. In certain embodiments, these compositions are prepared by condensing a C4 to C16 poly basic acid, monobasic acid or derivative thereof with a polyamine comprising a primary amino group, and in the presence of an optional organic diluent. Certain specific polyamidopolyamine and a non-polymeric amidoamine formulae and compositions containing same are disclosed, as are methods of use of these compositions.

Abstract: Compositions useful in preventing fungal and bacterial growth in fibrous substrates, e.g., paper, are provided. These compositions also advantageously do not corrode metal substrates that are attached and/or adjacent to the fibrous substrate. The compositions contain didecyl dimethyl ammonium bicarbonate and didecyl dimethyl ammonium carbonate (DDABC), a water-soluble cationic salt of ethylene diamine tetraacetic acid, optionally water, and optionally an agent which complexes said water-soluble cationic salt of ethylene diamine tetraacetic acid. Also provided are products containing these compositions and methods of using the same.
