Abstract

A paper tissue and products made from paper tissue, such as paper handkerchiefs, facial tissues, bath and cosmetic tissues, paper tissue wipes of any kinds and the like. The invention describes both the process for making a smooth and absorbent lotioned paper tissue, with high transferability of the lotion. The process steps comprises the steps of (a) providing a paper tissue web continuously moving next to a lotion application unit comprising at least one rotating surface, (b) transferring said lotion onto one rotating surface,’(c) expulsing said lotion from the said rotating surface into a stream of lotion droplets, by primarily the centrifugal force of the rotation of said rotating surface, (d) intercepting said paper tissue with said stream of lotion droplets. The invention also describes a paper tissue comprising a lotion distributed as discrete deposits on its surface. The deposits have a high local concentration of lotion and cover a relatively small area of the tissue.

Claims

1. A paper tissue having first and second opposed surfaces, comprising a lotion comprising an immobilizing agent, a transferable agent, and an emollient on the first surface of said paper tissue, said lotion being present in substantially discrete deposits on said first surface and covering larger than 70% of the total area of the first surface, and wherein said deposits have an average basis weight of from 11 g/sqm to 22.7 g/sqm.

2. The paper tissue of claim 1 wherein the basis weight of said lotion on said tissue is equal or less than 9 g/sqm.

3. The paper tissue of claim 1, wherein a ratio R₃ is defined as

4. The paper tissue of claim 1, wherein a ratio R₁ is defined as

5. The paper tissue of claim 2, wherein ratio R₂ is defined as

6. The paper tissue of claim 1 wherein 20% or more of the area affected by deposits is covered with deposits larger than 0.005 sqmm.

7. A paper tissue product comprising the tissue of claim 1 wherein said paper tissue product is a multiply tissue product of at least 2 plies having 2 external surfaces and at least 2 internal surfaces and wherein any of said external surfaces has more lotion than its corresponding internal surface.

8. A paper tissue product comprising the tissue of claim 1 wherein said paper tissue product is a multiply tissue of at least 3 plies having at least one 1 internal ply and 2 external plies and wherein said external plies taken together comprise 60% (by weight) or more of the total amount of lotion of said paper tissues product.

9. The paper tissue of claim 1 wherein said lotion basis weight on said tissue is at least 0.3 g/sqm.

10. The paper tissue of claim 1 wherein said lotion comprises at least 30% (w/w) of stearyl alcohol, at least 20% (w/w) of petrolatum and at least 10% (w/w) of mineral oil.

11. The paper tissue of claim 1 wherein said lotion comprises at least 50% (w/w) of a sucrose ester of a fatty acid and at least 10% (w/w) of stearyl alcohol.

12. The paper tissue of claim 1 wherein said lotion comprises between 0.01% (w/w) and 5% (w/w) of 2-isopropyl-N,2,3 trimethylbutyramide.
