There is provided a personal care product having a vapor sweep comprising a material which reacts with water or urine to form vapor at a rate capable of displacing at least 5, and preferably at least 10, percent of the air volume within said product per minute. This vapor generation sweeps water vapor and humidity from the personal care product, such as a diaper, and so it's believed will contribute to skin health. Materials that, upon reaction with water or urine, produce large volumes of carbon dioxide may be incorporated into the various components of standard personal care products to achieve the objective of this invention. Such materials include leavening agents. Additionally, a seal may be added to the personal care product to encourage the generated vapor to travel a longer path prior to exiting the product in order to maximize water vapor removal.

1. A personal care product for use adjacent the body of a wearer, and comprising a structure which defines a spatial path for the flow of vapor out from the product, the personal care product further comprising a vapor generating material that reacts with water or urine in order to generate vapor at a rate capable of displacing at least 5 percent of the air volume between a wearer of said product and said product, per minute, when said product is being worn, or at least at a rate of about 0.125 cc/sec, whereby as said vapor generating material reacts during product use, the vapor is directed so as to sweep vapor away from the product to a location out of the personal care product. 2. The personal care product of claim 1 wherein said vapor is generated at a rate of about 0.25 cc/sec. 3. The personal care product of claim 1 wherein said material is a leavening agent. 4. The personal care product of claim 3 wherein said leavening agent is selected from the group consisting of sodium bicarbonate, sodium aluminum sulfate and calcium sulfate. 5. The personal care product of claim 1 selected from the group consisting of diapers, training pants, absorbent underpants, adult incontinence products and wound care products. 6. The product of claim 5 wherein said personal care product is an adult incontinence product. 7. The product of claim 5 wherein said personal care product is a diaper. 8. The product of claim 5 further comprising a seal disposed to contact a wearer, whereby vapor is directed along a path during product use, between the body of the wearer and the product via said seal, to a location out of the product. 9. The product of claim 8 wherein said seal is disposed on a front of said product. 10. The product of claim 8 wherein said seal is disposed on a back of said product. 11. An article for use adjacent the skin of a wearer when worn, and of a structure defining a spatial path between the skin of the wearer and the article itself for the flow of vapor, the article including a vapor sweep system, with the vapor sweep system comprising a chemical that will react with water or urine to release vapor at a rate of at least 15 cm3/min., whereby upon said chemical reaction, said vapor sweep system sweeps air contained between the skin of the wearer and the article itself to a location out of the article. 12. The article of claim 11 wherein said chemical is located within fibers. 13. The article of claim 11 wherein said chemical is located within at least one bag, into which water vapor can diffuse. 14. The article of claim 11, wherein said article is selected from the group consisting of personal care products and articles of clothing. 15. A personal care product for use adjacent the body of a wearer, and comprising a structure which defines a spatial path for the flow of vapor out from the product, the personal care product further comprising a vapor generating material that reacts with water or urine in order to generate vapor at a rate capable of displacing at least 5 percent of the air volume between a wearer of said product and said product, per minute, when said product is being worn, or at least at a rate of about 0.125 cc/sec, whereby as said vapor generating material reacts during product use, the vapor exits the personal care product.
