<p>A method of moisturizing mammalian skin membranous tissue is disclosed. The composition utilized in this method includes a bioadhesive polymer as the moisturizing agent. The bioadhesive is a water-swellable, but water-insoluble, particulate, fibrous, cross-linked carboxy-functional polymer containing (a) a plurality of repeating units of which at least about 80 percent contain at least one carboxyl functionality, and (b) about 0.05 to about 1.5 percent cross-linking agent substantially free from polyalkenyl polyether. The composition is contacted with the skin or mucous membrane to be moisturized, and that contact is maintained for a time period sufficient to moisturize the contacted area.</p> |
