    Abstract: The invention provides methods and compositions for softening paper. An inventive composition and method of its use softens paper products (like tissue paper) by de-bonding its cellulose fibers and by improving the smoothness of the resulting paper. The invention forms a surfactant-polymer complex that attaches de-bonding non-ionic surfactants to cellulose fibers that would otherwise not be retained by the cellulose fibers. This complex prevents the fibers from bonding with each other and makes the paper product smoother. Best of all, the composition is environmentally superior and is a non-toxic.

    Abstract: Wet strength resins for paper are prepared by a process comprising the following steps in sequence: (1) reacting a polyamidoamine with an epihalohydrin until the amount of unreacted epihalohydrin present is less than about 10% by weight of the amount of epihalohydrin charged, (2) adding a water-soluble, nonpolymeric amine in an amount of about 0.1 to about 50 mole %, based on the amine in the polyamidoamine, and (3) heating to effect crosslinking. An optional amine additive reaction step can be included after step (2). A nonhalogen acid such as sulfuric acid can be added toward the end of the crosslinking step to decrease the total organic halogen content and increase the wet strengthening effectiveness.
