ABSTRACT:
Tissue paper products comprising a two component chemical softener composition and binder materials, either permanent or temporary wet strength binders, and/or dry strength binders are disclosed. The two component chemical softening composition comprises an ester-functional ammonium compound and a polysiloxane compound. Preferred ester-functional ammonium compounds include diester dialkyl dimethyl ammonium salts such as diester di(touch hardened)tallow dimethyl ammonium chloride and/or di(hydrogenated)tallow dimethyl ammonium chloride. Preferred polysiloxanes include amino-functional polydimethyl polysiloxanes wherein less than about 10 mole percent of the side chains on the polymer contain an amino-functional group.
