  • Patent number: 6602592
    Abstract: The present invention provides a moisture-retentive cooling gel, a laminate thereof, and a moisture-retentive cooling plaster, which offer moisture-retaining and cooling effects for a controlled duration and have superior functionality, e.g., capability of delivering and transporting an effective ingredient such as a pharmacological active ingredient, a perfume or a deodorant. The moisture-retentive cooling gel comprises: a water-retentive matrix (a1) of a water-soluble polymer having a water content of not lower than 40 wt %; and fibers (f) dispersed in the water-retentive matrix, the fibers (f) having a hydrophilic property at least at surfaces thereof, some of the fibers (f) being exposed on a surface of the water-retentive matrix (a1). The gel has a higher water content and a higher water vaporization rate. An endothermally water-dissolvable compound may be retained in the water-retentive matrix and/or the fibers for enhancement of the cooling capacity of the gel.
