The subject of the present invention is therefore a film-forming composition intended to be applied to the skin, integuments or mucous membranes that contains at least two grades of hydroxypropyl cellulose, at least one of which has a molecular weight of at least 800 000 and the other has a molecular weight of less than 400 000, at least one plasticizer, at least one organic solvent and at least one inorganic solvent, characterized in that: (a) the hydroxypropyl cellulose having a molecular weight of at least 800 000 represents from 0.2% to 4% by weight of the total weight of the composition, (b) the hydroxypropyl cellulose having a molecular weight of less than 400 000 represents from 0.2% to 20% by weight of the total weight of the composition, (c) the plasticizer represents from 0.5% to 10% by weight of the total weight of the composition, (d) the inorganic solvent represents from 10% to 60% by weight of the total weight of the composition, (e) the organic solvent represents from 40% to 80% by weight of the total weight of the composition. |
