Abstract

A superior soft tissue product, such as facial tissue, bath tissue or paper towels and the like, can be made applying, on the surface(s) of the tissue, large numbers of individual deposits of a melted hydrophilic composition comprising a high molecular weight polyethylene glycol, a fatty alcohol (C₁₄ -C₃₀) and lipophilic emollients or solvents, including water, and thereafter resolidifying the composition to form a distribution, preferably a uniform distribution, of solid deposits on the surface(s) of the tissue. Because the composition is a solid at room temperature and rapidly solidifies after deposition, it has less tendency to penetrate and migrate into the sheet. These solid deposits are characterized by a penetration hardness of from about 5 to about 360 millimeters.

Claims

1. A soft tissue or towel product having two outer surfaces, wherein one or both outer surfaces of the product have solidified deposits of a composition comprising from about 30 to about 90 weight percent hydrophilic solvent, from about 10 to about 50 weight percent high molecular weight polyethylene glycol having a molecular weight of about 720 or greater, and from about 5 to about 40 weight percent of a C₁₄ to C₃₀ fatty alcohol, said composition having a melting point from about 30°

C. to about 70°

C. and a penetration hardness of from about 5 millimeters to about 360 millimeters.

2. The product of claim 1 wherein the composition is present in an amount of from about 0.5 to about 30 weight percent based on the weight of the product.

3. The product of claim 1 wherein the hydrophilic solvent comprises water.

4. The product of claim 1 wherein the hydrophilic solvent comprises propylene glycol.

5. The product of claim 1 wherein the hydrophilic solvent comprises low molecular weight polyethylene glycol.

6. The product of claim 1 wherein the hydrophilic solvent comprises glycerin.

7. The product of claim 1 wherein the hydrophilic solvent comprises hydrogenated starch hydrolysate.

8. The product of claim 1 wherein the fatty alcohol is cetyl alcohol.

9. The product of claim 1 wherein the fatty alcohol is stearyl alcohol.

10. The product of claim 1 wherein the fatty alcohol is arachidyl alcohol.

11. The product of claim 1 wherein the fatty alcohol is behenyl alcohol.

12. The product of claim 1 wherein the molecular weight of the high molecular weight polyethylene glycol is from about 720 to about 1,840,000.

13. The product of claim 1 wherein the molecular weight of the high molecular weight polyethylene glycol is from about 1400 to about 440,000.

14. A method of making a soft tissue or towel product comprising:

(a) heating a composition comprising a hydrophilic solvent, a high molecular weight polyethylene glycol and a fatty alcohol, to a temperature above the melting point of the composition, causing the composition to melt, said composition having a melting point of from about 30°

C. to about 70°

C.;

(b) applying the melted composition to one or both surfaces of a tissue web in spaced-apart deposits; and

(c) resolidifying the deposits of the melted composition, said resolidified composition having a penetration hardness of from about 5 to about 360 millimeters.

15. The method of claim 14 wherein the melted composition is applied by printing.

16. A softening composition comprising from about 30 to about 90 weight percent hydrophilic solvent, from about 10 to about 50 weight percent high molecular weight polyethylene glycol having a molecular weight of about 720 or greater, and from about 5 to about 40 weight percent of a C₁₄ to C₃₀ fatty alcohol, said composition having a melting point from about 30°

C. to about 70°

C. and a penetration hardness of from about 5 millimeters to about 360 millimeters.

18. The composition of claim 16 wherein the fatty alcohol is selected from the group consisting of cetyl alcohol, stearyl alcohol, arachidyl alcohol and behenyl alcohol.

19. The composition of claim 16 wherein the amount of hydrophilic solvent is from about 40 to about 70 weight percent.
