Abstract
A patch is disclosed, which comprises a water-soluble adhesive sheet (a), and a patch is disclosed, which comprises a water-soluble adhesive sheet (a) and a water-soluble protective material (b) laminated thereon. This patch is convenient in handling and achieves high merit. Also, it can be applied to the skin so as to exhibit excellent warm-bathing effects on the application site.
Claims13
A patch comprising a water-soluble adhesive sheet (a) and a water-soluble protective material (b) laminated thereon selected from the group consisting of a non-ionic water-soluble polymer, a gelatin and an emulsion polymer,
- wherein said non-ionic water-soluble polymer is polydimethyl acrylamide, polyvinyl pyrrolidone, polyetylene glycol monomethacrylate, poly-2-ethyl-2-oxazoline, polyvinyl alcohol or pullulan,
- said gelatin has a weight average molecular weight of 20,000 to 100,000, and
- wherein said emulsion polymer is an acralate resin emulsion.
A method of bathing which comprises applying a patch on skin comprising:
- a water-soluble adhesive sheet (a) and a water-soluble protective material (b) laminated thereon selected from the group consisting of a non-ionic water-soluble polymer, a gelatin and an emulsion polymer,
- wherein said non-ionic water-soluble polymer is polydimethyl acrylamide, polyvinyl pyrrolidone, polyethylene glycol monomethacrylate, poly-2-ethyl-2-oxazoline, polyvinyl alcohol or pullulan,
- said gelatin has a weight average molecular weight of 20,000 to 100,000, and
- wherein said emulsion polymer is an acrylate resin emulsion.
A method which of bathing which comprises pouring a patch into bathwater comprising:
- a water-soluble adhesive sheet (a) and a water-soluble protective material (b) laminated thereon selected from the group consisting of a non-ionic water-soluble polymer, a gelatin and an emulsion polymer,
