Claims24
A method of treatment of a minor injury to the skin, which method comprises topically applying to said injured area an aqueous formulation comprising a water-soluble or a water-dispersible polymeric material, which polymeric material is capable of:
- (i) adhering to the skin;
- and
- (ii) acting as a barrier to moisture but not to oxygen,
- to cover said injured area, and then allowing water within the aqueous formulation to evaporate to leave a film comprising said polymeric material that covers said injured area, to treat said minor injury;
- wherein said aqueous formulation is an aqueous solution of said polymeric material comprising a combination of at least:
- a first polymer comprising a polyvinyl ester polymer selected from the group consisting of polyvinyl acetate (PVAc), polyvinyl benzoate, polyvinyl butyrate, polyvinyl formate, polyvinyl propionate, and polyvinyl stearate;
- and
- a second polymer comprising a styrene/acrylate copolymer;
- and wherein the weight ratio between the first polymer and the second polymer is in the range of about 3.2:1 to about 1:1.
