<p>PURPOSE: To enable to moisten the surface of skin, to absorb moisture to restore the natural flexibility to fit in dents of eyes or wrinkles, by including a flexible net to reinforce the activity in a thin film composed of hydrophilic gel. CONSTITUTION: A net is composed of woven fabric with thickness of 0.01-2mm and about 2-100 meshes/cm. In this case, especially, the ratio of the area of the net meshes to the whole area is to be 5-80%. It is preferable to compose gel of water soluble or water swelling polymer with dry extracts of 0.5-50wt.%. Polyvinyl alcohol, alkali metal salts of cross-linked carboxymethylcellulose, alkali metal salts of polyacrylate, etc., are used as the polymer. Thus, as the combination of net/gel is made flexible, a mask is made to quickly absorb moisture in a wet treated part and, consequently, the mask can be fit to a part of a face or a body.</p> |
