Fibrous structures comprising a surfactant
Fibrous structures, for example sanitary tissue products, such as toilet tissue, having one or more neat surfactant components on at least one exterior surface, methods for making same, and methods for removing fecal matter from a user's skin are provided.
1. A sanitary tissue product comprising a wet-laid fibrous structure, wherein the sanitary tissue product comprises an exterior surface comprising a neat surfactant component and a surface softening composition, wherein the neat surfactant component comprises one or more neat surfactants free from admixture, dilution, encapsulation and emulsion such that the one or more neat surfactants are applied to a user's skin during use of the sanitary tissue product, and wherein the neat surfactant component is present on at least a portion of the exterior surface of the sanitary tissue product, and wherein the surface softening composition comprises a surface softening agent selected from the group consisting of: silicones, quaternary ammonium compounds, polyhydroxy compounds and mixtures thereof, wherein the surface softening composition is present on the wet-laid fibrous structure between a surface of the wet-laid fibrous structure and the neat surfactant component.
2. The sanitary tissue product according to claim 1 wherein the neat surfactant component comprises two or more neat surfactants.
3. The sanitary tissue product according to claim 1 wherein at least one of the one or more neat surfactants is selected from the group consisting of: neat nonionic surfactants, neat anionic surfactants, neat amphoteric surfactants, neat zwitterionic surfactants, cationic surfactants, and mixtures thereof.
4. The sanitary tissue product according to claim 1 wherein the neat surfactant component is present on the exterior surface of the sanitary tissue product at a level of at least 0.0001% by weight of the fibrous structure.
5. The sanitary tissue product according to claim 1 wherein the exterior surface comprises two or more neat surfactant components present thereon.
6. The sanitary tissue product according to claim 1 wherein the fibrous structure comprises a plurality of fibrous elements.
7. The sanitary tissue product according to claim 6 wherein the plurality of fibrous elements comprises a plurality of fibers.
8. The sanitary tissue product according to claim 7 wherein the plurality of fibers comprises pulp fibers.
9. The sanitary tissue product according to claim 8 wherein the pulp fibers comprise wood fibers.
10. The sanitary tissue product according to claim 7 wherein the plurality of fibers comprises a plurality of synthetic fibers.
11. The sanitary tissue product according to claim 6 wherein the plurality of fibrous elements comprises a plurality of filaments.
12. The sanitary tissue product according to claim 1 wherein the fibrous structure is a through-air-dried fibrous structure.
13. The sanitary tissue product according to claim 1 wherein the fibrous structure is a conventional wet pressed fibrous structure.
14. The sanitary tissue product according to claim 1 wherein the fibrous structure is a belt creped fibrous structure.
15. The sanitary tissue product according to claim 1 wherein the fibrous structure is a fabric creped fibrous structure.
16. The sanitary tissue product according to claim 1 wherein the fibrous structure is an embossed fibrous structure.
17. A multi-ply sanitary tissue product comprising a first fibrous structure ply comprising a sanitary tissue product according to claim 1 and a second fibrous structure ply.
18. A method for making a sanitary tissue product according to claim 1 wherein the method comprises the steps of applying a surface softening composition to a surface of a wet-laid fibrous structure; and applying a neat surfactant component comprising one or more neat surfactants free from admixture, dilution, encapsulation and emulsion to the surface softening composition such that the surface softening composition is present between the neat surfactant component and the surface of the wet-laid fibrous structure such that the neat surfactant component forms an exterior surface of a sanitary tissue product comprising a wet-laid fibrous structure.
