    • The present invention is a composition in the form of a soluble sheet or film which has a variety of uses, particularly in the personal care field. Such sheets are preferably water soluble. An important component of these water soluble sheets is a “base composition,” which includes a water soluble film forming polymer, a polyvinyl alcohol, and a humectant such as propylene glycol. Surfactant may be added to the liquid base composition so that, when the composition is dried into sheet form, the sheet will generate foam when exposed to water and have cleansing properties. Skin care ingredients may also be added to the base composition in addition to or in place of the surfactant. Volatile alcohols or hydrocarbons may also be incorporated into the liquid base composition to facilitate drying of the composition to form the flexible sheet product.
    • 本发明是一种具有多种用途的可溶性片或薄膜形式的组合物,特别是在个人护理领域。 这样的片材优选是水溶性的。 这些水溶性片材的重要组分是“基础组合物”,其包括水溶性成膜聚合物,聚乙烯醇和保湿剂如丙二醇。 表面活性剂可以添加到液体基料组合物中,使得当组合物干燥成片状时,当暴露于水中时,片材将产生泡沫并具有清洁性能。 除了表面活性剂之外或代替表面活性剂,皮肤护理成分也可以加入到基础组合物中。 挥发性醇或烃也可以并入液体基础组合物中,以促进组合物的干燥以形成柔性片状产品。
