ABSTRACT:
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.
