A film forming composition comprises a film forming component and a solvent, wherein the film forming component comprises 0-50wt% of a first water soluble polymer, 0.3-40wt% of a second water soluble polymer, 0-15wt% of plasticizer and 50-70wt% of active ingredient. The first and second water soluble polymers have a Tg of -52℃ to 216℃, and difference of Tg values of the first and second water soluble polymer is 62-268℃. The film formed by the film forming composition capable to load high content of active ingredient and lead to fast absorption of active ingredient is provided. |
