embodiments
[0190]In addition to the embodiments described above, in the examples and in the claims, other embodiments described herein include the following:
[0191]In one embodiment, a composition comprises a polyamidopolyamine produced by the reaction of a polybasic acid and primary polyamine, which is linear, cyclic, branched or cross-linked, said polyamidopolyamine having a molecular weight of about 500 to about 100,000 and having one or more repeating pendant amino groups, wherein said polyamidopolyamine is of the Formula A wherein each polybasic acid is a dimer acid; each primary polyamine is independently a diamine, a triamine, or a tetraamine or an amine comprising 5 or more free amino groups; a and a′ are independently 1 or 2; b is 0, 1 or 2; and r is a number between 2 to about 10, including both endpoints of the range. In another embodiment, this composition is formed by the reaction having a 2:1 mole ratio of polyamine to dimer acid.
[0192]In another embodiment, the composition furthe...

Antimicrobial Activity of Polyamidopolyamine Composition 3533-171
[0226]The results of this experiment are shown in FIG. 1.
[0227]A polyamidopolyamine composition of Formula A, referred to as 3533-171, was produced by a condensation reaction of 2 moles of the Jeffamine® T403 polyetheramine (Huntsman Corporation) polyamine and 1 mole of adipic acid. The T403 amine is a trifunctional primary amine having an average molecular weight of approximately 440 with its amine groups located on secondary carbon atoms at the ends of aliphatic polyether chains.
[0228]The reaction was conducted at 160-165° C., with water as a diluent added at the end of the reaction. The final composition contained greater than about 73% of the polyamidopolyamine, up to 15% by weight of free T-403 polyamine and about 12.8% water. The composition has a cloud point (inverse solubility) at about 31° C. (88° F.).
[0229]The composition was diluted to 0.75% in water and was measured for the time in seconds that foam collaps...

Antimicrobial Activity of Polyamidopolyamine Composition 3587-17
[0231]The results of this experiment are shown in FIG. 2.
[0232]A polyamidopolyamine composition of Formula A, referred to as 3587-17, was produced by a condensation reaction of 2 moles of T403 polyamine (Huntsman) with 1 mole of azelaic acid, with triethanolamine (TEA) as a solvent. The reaction was conducted at 160-165° C. The final composition contained about 46% by weight of the polyamidopolyamine, up to 9.4% by weight of free T-403 polyamine and about 45% by weight triethanolamine. The composition has a cloud point (inverse solubility) at about 24° C. (75° F.).
[0233]The composition 3587-17, diluted to 0.75% in water was measured for the time in seconds that foam collapses to zero foam. The decay was less than 15 seconds.
[0234]The polyamidopolyamine-containing composition 3587-17 was evaluated for anti-microbial ability in the following assay. The pH for the composition was adjusted to approximately 9.3. The composit...
