Fibrous cellulose material useful in the manufacture of soft, absorbent paper products such as paper towels, facial tissues, and toilet tissue are disclosed. The paper products contain a chemical softening composition comprising a mixture of a quaternary ammonium compound and a polyhydroxy compound. Preferred quaternary ammonium compound include dialkyldimethylammonium salts such as di(hydrogenated) tallow dimethyl ammonium chloride and di(hydrogenated) tallow dimethyl ammonium methyl sulfate. Preferred polyhydroxy compounds are selected from the group consisting of glycerol, and polyethylene glycols and polypropylene glycols having a weight average molecular weight from about 200 to 4000. The chemical softening compositions are prepared by first mixing the polyhydroxy compound into the quaternary ammonium compound at a specific temperature range wherein the polyhydroxy compound is miscible with the quaternary ammonium compound and then diluting the mixture with water at an elevated temperature to form an aqueous vesicle dispersion suitable for treating the fibrous cellulose material. |
