Abstract: A polymerized hydrogel composition for hydrating or dehydrating a surface, particularly a dermatological surface, to which it is applied and a method for forming the composition. The composition is comprised of a mixture of two polymerizable materials, a two-part redox catalyst system and a two-part polymerization medium. The percentage by weight of each element in the composition may be varied within stated percentage ranges and depending to the desired application. The rate at which hydration or dehydration occurs may be controllably altered by varying the percentages of certain of the composition elements and by adding either or both of a fibrous filler material and a humectant to the composition.

Abstract: A polymerized hydrogel composition and applicator for hydrating or dehydrating a surface, particularly a dermatological surface, to which it is applied and a method for forming the composition. The composition is comprised of a mixture of two polymerizable materials, a two-part redox catalyst system and a two-part polymerization medium. The percentage by weight of each element in the composition may be varied within stated percentage ranges. The rate at which hydration or dehydration occurs may be controllably altered by varying the percentages of certain of the composition elements. The applicator includes a thermoplastic center section and two reservoir sections each having a reservoir storage area for holding moisture and/or medicaments. The composition is mechanically bonded onto each of the reservoir sections and then hydrated. The applicator is designed for insertion into a human mouth after hydration and is used for treating xerostomia.
