WIPO Patent Application WO/2001/008641
Kind Code:
A2
Abstract:
The present invention relates to a substantially dry, disposable personal care article comprising: a) a water insoluble substrate comprising a first layer comprising: 1) a nonwoven ply; 2) a polymeric net arranged with said nonwoven ply; and b) a cleansing component disposed adjacent to said first layer, wherein said component comprises from about 10 % to about 1000 %, by weight of the water insoluble substrate, of a lathering surfactant. The present invention further relates to a substantially dry, disposable personal care article suitable for conditioning wherein the above-described article comprises a therapeutic benefit component, disposed adjacent to said water insoluble substrate, wherein said component comprises from about 10 % to about 1000 %, by weight of the water insoluble substrate, of a therapeutic benefit component in addition to or in lieu of the cleansing component. These articles have been found to be particularly useful for personal cleansing applications, namely for the skin and hair.

Claims:
WHAT IS CLAIMED IS:
| 1. | A substantially dry, disposable personal care article suitable for cleansing characterized in that said article comprises: a) a water insoluble substrate comprising a first layer comprising: 1) a nonwoven ply; 2) a polymeric net arranged with said nonwoven ply; and b) a cleansing component disposed adjacent to said first layer, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a lathering surfactant. |
| 2. | The article of Claim 1 wherein the polymeric net comprises materials selected from the group consisting of nylon, rayon, polyolefin, polyester, and combinations thereof. |
| 3. | The article of Claim 1 wherein the first layer is heated and cooled such that the polymeric net shrinks in the XY direction and gives the first layer macroscopic threedimensional character. |
| 4. | A method of cleansing the skin and/or hair, said method comprising the steps of: a) wetting the article of Claim 1; and b) contacting the skin or hair with the wetted article. |
| 5. | A substantially dry, disposable personal care article suitable for cleansing characterized in that said article comprises: a) a water insoluble substrate comprising: 1) a first layer comprising: a) a nonwoven ply; b) a polymeric net arranged with the nonwoven ply; and 2) a second layer disposed adjacent to said first layer; and b) a cleansing component disposed adjacent to said first layer and second layers, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a lathering surfactant. |
| 6. | The article of Claim 5 wherein said second layer is a material selected from the group consisting of nonwovens, wovens, and polymeric films. |
| 7. | The article of Claim 5 wherein said first layer and said second layer are spot bonded to one another. |
| 8. | A substantially dry, disposable personal care article suitable for conditioning characterized in that said article comprises: a) a water insoluble substrate comprising: 1) a nonwoven ply; 2) a polymeric net arranged with the nonwoven ply; and b) a therapeutic benefit component, disposed adjacent to said water insoluble substrate, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a therapeutic benefit. |
| 9. | The article of Claim 8 wherein said therapeutic benefit agent is selected from the group consisting of hydrophobic conditioning agents, hydrophilic conditioning agents, structured conditioning agents, and combinations thereof. |
| 10. | A substantially dry, disposable personal care article suitable for cleansing and conditioning characterized in that said article comprises: a) a water insoluble substrate comprising a first layer comprising: 1) a nonwoven ply; 2) a polymeric net arranged with the nonwoven ply; b) a cleansing component disposed adjacent to said first layer, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a lathering surfactant; and c) a therapeutic benefit component, disposed adjacent to said water insoluble substrate, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a therapeutic benefit. |
| 11. | A personal care kit comprising the article of Claim 1 and an additional article that comprises a substrate and a therapeutic benefit component. |
