    摘要: Cosmetic and/or therapeutic film former compositions for a topical use and for optional delivery of active ingredients to the skin are provided. More particularly, film forming compositions are provided, containing 1 to 50 wt % polyurethane, preferably polyurethane-1; at least 0.01 wt %, but less than 2.0 wt %, cellulose and 0.05 to 5.0 wt % magnesium aluminum silicate; wherein the film forming composition forms a uniform mist when discharged from a spray bottle or pump sprayer. A method for applying a film forming composition to an individual's skin is also provided including spraying the film forming composition onto the skin, wherein the film forming composition contains 1 to 50 wt % polyurethane; at least 0.01 wt %, but less than 2.0 wt %, cellulose and 0.05 to 5.0 wt % magnesium aluminum silicate; and wherein the film forming composition forms a uniform mist when sprayed.
