Abstract:

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 its 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.
