Zusammenfassung: | Methods and compositions for forming protective and/or medicated films on bo dy tissue. Liquid compositions contain a hydrophobically modified polymer, other than an esterified lower-hydroxyalky l- subsituted cellulose, suspended or dissolved in a solven. The modified polymer is soluble in the solvent but insoluble in body fluids. The compositions may optionally contain a separate medicinal component, i.e., one which is present in addition to any medications, if any , present in the solvent, in the modified polymer and in any other additive components such as flavors, skin penetrants, preservatives, other solvents for the additives, etc. A protective and/or medicated film is formed in situ upon body tissue by applying the liquid composition to the tissue and separating the solvent from the composition, e.g., by vaporization. |
