Abstract

Fibrous structures having thereon a surface softening composition containing a metathesized unsaturated polyol ester, sanitary tissue products made from such fibrous structures and methods for making same are provided.

Claims

1. A fibrous structure comprising a surface comprising a surface softening composition comprising a metathesized unsaturated polyol ester.

2. The fibrous structure according to claim 1 wherein the metathesized unsaturated polyol ester is selected from the group consisting of:

a metathesized natural oil composition comprising olefins, esters, and mixtures thereof;

a metathesized natural oil composition having a number average molecular weight in the range of from about 100 g/mol to about 150,000 g/mol, a weight average molecular weight in the range of from about 1,000 g/mol to about 100,000 g/mol, a z-average molecular weight in the range of from about 5,000 g/mol to about 1,000,000 g/mol, and a polydispersity index of from about 1 to about 20, wherein the metathesized natural oil composition is metathesized at least once; and

mixtures thereof.

3. The fibrous structure according to claim 1 wherein the metathesized unsaturated polyol ester is selected from the group consisting of a metathesized vegetable oil, a metathesized animal fat, a metathesized algae oil and mixtures thereof.

4. The fibrous structure according to claim 1 wherein the metathesized unsaturated polyol ester is selected from the group consisting of metathesized canola oil, metathesized rapeseed oil, metathesized coconut oil, metathesized corn oil, metathesized cottonseed oil, metathesized olive oil, metathesized palm oil, metathesized peanut oil, metathesized safflower oil, metathesized sesame oil, metathesized soybean oil, metathesized sunflower oil, metathesized linseed oil, metathesized palm kernel oil, metathesized tang oil, metathesized jatropha oil, metathesized mustard oil, metathesized castor oil, metathesized camelina oil, metathesized pennycress oil, metathesized derivatives of these oils, and mixtures thereof.

5. The fibrous structure according to claim 1 wherein the metathesized unsaturated polyol ester has an iodine value (IV) that ranges from 5 to 100.

6. The fibrous structure according to claim 1 wherein the surface softening composition further comprises a surface softening agent selected from the group consisting of:

silicones, quaternary ammonium compounds, and mixtures thereof.

7. The fibrous structure according to claim 1 wherein the fibrous structure further comprises a lotion composition.

8. The fibrous structure according to claim 1 wherein the fibrous structure is a through-air-dried fibrous structure.

9. The fibrous structure according to claim 1 wherein the fibrous structure is a conventionally dried fibrous structure.

10. The fibrous structure according to claim 1 wherein the fibrous structure is belt creped.

11. The fibrous structure according to claim 1 wherein the fibrous structure is fabric creped.

12. The fibrous structure according to claim 1 wherein the fibrous structure comprises fibers.

13. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a Slip Stick Coefficient of Friction of less than 360 as measured according to the Slip Stick Coefficient of Friction Test Method.

14. The fibrous structure according to claim 1 wherein the fibrous structure exhibits a TS7 Softness Value of less than 9 as measured according to the Softness Test Method.

15. A single- or multi-ply sanitary tissue product comprising a fibrous structure according to claim 1.

16. The sanitary tissue product according to claim 15 wherein the sanitary tissue product is toilet paper.

17. A process for treating a surface of a fibrous structure, the process comprising the step of applying a surface softening composition comprising a metathesized unsaturated polyol ester to the surface of the fibrous structure.

18. The process according to claim 17 wherein at least 10#/ton of the surface softening composition is applied to the surface of the fibrous structure.

19. The process according to claim 17 wherein the process further comprises the step of applying a lotion composition to the surface of the fibrous structure.

20. The process according to claim 17 wherein the process further comprises the step of applying an additional surface softening agent selected from the group consisting of:

quaternary ammonium compounds, silicones, and mixtures thereof, to the surface of the fibrous structure.
