Summary:PROBLEM TO BE SOLVED: To provide a multifunctional barrier coating which provides moisture, odor as well as taste barrier for various nutraceutical and pharmaceutical solid preparations and which is easy to produce from a powder and easy to apply to the solid dosage form.SOLUTION: A film coating composition comprises: a water soluble film former, such as hydroxypropyl cellulose, hydroxypropyl methylcellulose, hydroxyethyl cellulose, starches, modified starches; and one or more hydrophobic compounds, such as metal salt of higher fatty acids, higher fatty alcohol natural wax either from vegetable, animal origin or synthetic wax. Optionally, the film coating composition includes plasticizers, colorants, such as pigments, and/or flow aids. 【課題】種々の栄養補助食品および医薬の固体製剤のために湿気、臭気ならびに風味バリヤを提供することができ、また、粉末から製造するのが容易であり、また固体剤形に塗布するのが容易である多機能性バリヤコーティングを提供する。【解決手段】水溶性フィルム形成剤、例えばヒドロキシプロピルセルロース、ヒドロキシプロピルメチルセルロース、ヒドロキシエチルセルロース、デンプン、改質デンプンなど、および1種または複数の疎水性化合物、例えば高級脂肪酸の金属塩、高級脂肪族アルコール、植物もしくは動物起源いずれかの天然ワックスまたは合成ワックスなどを含み、場合によってはさらに可塑剤、顔料などの着色剤および/または流動助剤が含まれるフィルムコーティング組成物を調製する。【選択図】なし
