ABSTRACT:
The invention disclosed is a hydrogel-forming wound dressing or skin coating material suitable for household and veterinary use, consisting substantially entirely of wound-compatible and skin-compatible ingredients and comprising a first hydrophilic polymer, selected from polymers or copolymers of acrylic acid, polymers or copolymers of methacrylic acid, polymers or copolymers of itaconic acid, polymers or copolymers of maleic acid and polymers or copolymers of 3-butene-1,2,3-tricarboxylic acid, or combinations thereof, a second hydrophilic polymer which is capable of interacting with the first polymer to produce, upon drying, a hydrogel of improved water resistance and film forming properties relative to the first polymer alone and water. This material is film forming and substantially transparent but capable of being made opaque.
