Abstract

The present invention provides a paper product having at least one ply, wherein only one outer surface of said tissue paper has a polyhydroxy compound and a lotion applied thereto.

Claims

1. A paper product having at least one ply, wherein only one outer surface of said paper product has a polyhydroxy compound comprising polyethylene glycol (PEG) having a molecular weight ranging from about 200 to about 2,000 applied thereto by slot extrusion and a lotion applied thereto, said paper product having a Wet Burst greater than about 80 grams, a Dynamic Coefficient of Friction of less than about 0.9, and a Bending Flexibility of less than about 50 mg*cm²/cm.

2. The paper product of claim 1 wherein said lotion comprises:

a. From about 10 percent to about 90 percent of a compound selected from the group consisting of oils, emollients, and waxes; and

,

b. Less than about 20 percent of water content.

3. The paper product of claim 2 wherein the lotion composition further comprises from at least about 15 percent to about 100 percent solids content.

4. The paper product of claim 1 further comprising a chemical softening agent.

5. The paper product of claim 1 wherein said paper product comprises from about 2.0 percent to about 25.0 percent of said lotion based upon a dry fiber weight of said paper product.

6. The paper product of claim 5 wherein said paper product comprises from about 4.0 percent to about 11.0 percent of said lotion based on the dry fiber weight of the paper product.

7. The paper product of claim 1 wherein said lotion comprises a compound selected from the group consisting of glycols, polyglycols, petrolatum, fatty acids, fatty alcohols, fatty alcohol ethoxylates, fatty alcohol esters and fatty alcohol ethers, fatty acid ethoxylates, fatty acid amides and fatty acid esters, hydrocarbon oils, squalane, fluorinated emollients, silicone oil, and mixtures thereof.

8. The paper product of claim 1 wherein said lotion comprises an emollient selected from the group consisting of petroleum-based emollients, fatty acid ester type emollients, alkyl ethoxylate type emollients, and combinations thereof.

9. The paper product of claim 1, wherein said polyhydroxy compound comprises from about 2.0 percent to about 30.0 percent of a water soluble polyhydroxy compound based upon a dry fiber weight of said paper product.

10. The paper product of claim 9, wherein said polyhydroxy compound comprises from about 5.0 percent to about 20.0 percent of said water soluble polyhydroxy compound based upon said dry fiber weight of said paper product.

11. The paper product of claim 10, wherein said polyhydroxy compound comprises from about 8.0 percent to about 15.0 percent of said water soluble polyhydroxy compound based upon said dry fiber weight of said paper product.

12. The paper product of claim 1, wherein said paper product has a basis weight ranging from between about 5 g/m² and about 120 g/m².

13. The paper product of claim 1, wherein said paper product has a density ranging from between about 0.01 g/cm³ and about 0.19 g/cm³.

14. The paper product of claim 1, wherein said paper product is creped.

15. A paper product having at least one ply, wherein only one outer surface of said paper product comprises from about 0.1 g/m² to about 36 g/m² of a polyhydroxy compound comprising polyethylene glycol (PEG) having a molecular weight ranging from about 200 to about 2,000 applied thereto by slot extrusion and from about 0.1 g/m² to about 30 g/m² of a lotion applied thereto, said paper product having a Bending Flexibility of less than about 50 mg*cm²/cm and a Mechanical Rub Test Value of greater than about 0.5 μ

g/cm².

16. The paper product of claim 15 wherein said paper product comprises from about 0.65 g/m² to about 12 g/m² of said polyhydroxy compound and from about 0.65 g/m² to about 10 g/m² of said lotion applied thereto.

17. A paper product having at least one ply, wherein only one outer surface of said paper product comprises from about 2.0 percent to about 25.0 percent of a lotion based upon a dry fiber weight of said paper product and from about 2.0 percent to about 30.0 percent of a water soluble polyhydroxy compound based upon a dry fiber weight of said paper product, said polyhydroxy compound comprising polyethylene glycol (PEG) having a molecular weight ranging from about 200 to about 2,000 applied by slot extrusion to said one outer surface, said paper product having a Wet Burst/Total Dry Tensile ratio of greater than about 0.12 inches and a Bending Flexibility of less than about 50 mg*cm²/CM.

18. The paper product of claim 17 further comprises from about 4.0 percent to about 11.0 percent of said lotion based on the dry fiber weight of said paper product from about 5.0 percent to about 20.0 percent of said water soluble polyhydroxy compound based upon said dry fiber weight of said paper product.
