Personal care products comprising supersaturated solutions and core compositions comprising activation means are disclosed. In one embodiment, a core composition comprising the activation means is surrounded by an encapsulation layer. The core composition comprising the activation means may be introduced into wet wipes such that, upon rupture and contact between the supersaturated solution and the activation means, the wet wipe solution is warmed resulting in a warm sensation on a user's skin. Any number of other active ingredients, such as biocides, can also be incorporated into the personal care product.

The wet wipe as set forth in claim 1 wherein the supersaturated solution is a supersaturated salt solution prepared from an aqueous solution of a salt, the salt being selected from the group consisting of sodium acetate, sodium sulfate, sodium thiosulfate, potash alum, calcium nitrate, potassium acetate, ammonium nitrate, potassium nitrate, lithium acetate, magnesium acetate, chromium alum, sodium carbonate, magnesium sulfate, sodium borate, sodium bromide, sodium chromate, calcium chloride, magnesium chloride, magnesium nitrate, disodium phosphate, urea nitrate, and hydrates thereof. 4. The wet wipe as set forth in claim 1 wherein the supersaturated solution is a supersaturated sugar solution prepared from an aqueous solution of a sugar, the sugar being xylitol. 5. The wet wipe as set forth in claim 1 wherein the supersaturated solution is present in the composition in an amount of from about 70% (by weight) to about 99.9% (by weight). 6. The wet wipe as set forth in claim 1 wherein the composition further comprises a plasticizer. 7. The wet wipe as set forth in claim 6 wherein the composition further comprises an emulsifying agent in combination with the plasticizer. 8. The wet wipe as set forth in claim 1 wherein the activation means is selected from the group consisting of sodium acetate, sodium sulfate, sodium sulfate decahydrate, sodium thiosulfate, potash alum, calcium nitrate, potassium acetate, ammonium nitrate, potassium nitrate, lithium acetate, magnesium acetate, chromium alum, sodium carbonate, magnesium sulfate, sodium borate, sodium bromide, xylitol, sodium chromate, calcium chloride, magnesium chloride, magnesium nitrate, disodium phosphate, urea nitrate, and hydrates thereof. 9. The wet wipe as set forth in claim 1 wherein the activation means is present in the core composition in an amount of from about 0.1% (by weight core composition) to about 80% (by weight core composition). 10. The wet wipe as set forth in claim 1 further comprising a moisture protective layer surrounding the encapsulation layer. 11. The wet wipe as set forth in claim 10 further comprising a fugitive layer surrounding the moisture protective layer. 12. The wet wipe as set forth in claim 1 wherein upon contact between the supersaturated solution and the activation means, the temperature of the wet wipe is increased by at least about 5° C. in less than about 20 seconds. 13. The wet wipe as set forth in claim 12 wherein the increased temperature of the wet wipe is maintained for at least about 5 seconds. 14. The wet wipe as set forth in claim 1 wherein the composition is a gelled composition and the gelled composition comprises a gelling agent in combination with the supersaturated solution. 15. The wet wipe as set forth in claim 14 wherein the gelled composition is present in the wet wipe in an amount of from about 3.0 grams per square meter to about 850 grams per square meter. 16. The wet wipe as set forth in claim 14 wherein the gelling agent is selected from the group consisting of fumed silica and laponite clay. 17. The wet wipe as set forth in claim 1 further comprising a first fluid-impermeable pouch and a second fluid-impermeable pouch, wherein the first fluid-impermeable pouch comprises the composition comprising the supersaturated solution and the second fluid-impermeable pouch comprises the core composition comprising the matrix material and activation means. 18. The wet wipe as set forth in claim 17 wherein the first fluid-impermeable pouch and second fluid-impermeable pouch are connected by a frangible seal. 19. The wet wipe as set forth in claim 1 further comprising a fibrous sheet material, the fibrous sheet material comprising the composition comprising the supersaturated solution. 20. A method of producing a wipe comprising: encapsulating an activation means within a core composition; and incorporating a composition comprising a supersaturated solution, and the core composition within a basesheet material.
