An emulsion containing a substantially water resistant film-forming copolymer phase and iodine is claimed. The polymer-in-water emulsion forms a film that is a substantially fluid resistant, low tack, flexible film which adheres to skin and releases iodine to skin. The addition of iodate to emulsion

An emulsion containing a substantially water resistant film-forming copolymer phase and iodine is claimed. The polymer-in-water emulsion forms a film that is a substantially fluid resistant, low tack, flexible film which adheres to skin and releases iodine to skin. The addition of iodate to emulsions having such a film-forming copolymer phase and iodine further enhances stability of the emulsion.

A film-forming emulsion, comprising: (a) a substantially water resistant film-forming copolymer phase comprising A, B and C monomers wherein A is a monomer wherein the corresponding homopolymer has a glass transition temperature less than about -15°C., and is present as about 15 to 80% of the total

A film-forming emulsion, comprising: (a) a substantially water resistant film-forming copolymer phase comprising A, B and C monomers wherein A is a monomer wherein the corresponding homopolymer has a glass transition temperature less than about -15°C., and is present as about 15 to 80% of the total weight of all monomers in the copolymer, B is a monomer wherein the corresponding homopolymer has a glass transition temperature of more than about -5°C., and is present as about 20 to 70% of the total weight of all monomers in the copolymer, and C is a monomer capable of complexing iodine and delivering it to the skin and is present as about 1 to 15% of the total weight of all monomers in the copolymer; (b) about 0.05 to 15% of iodine based on total emulsion weight; (c) an effective amount of an emulsifying agent; and (d) about 30 to 95% by weight of water; said monomers in the copolymer phase selected such that said emulsion, when applied to human skin in an amount sufficient to form a film having a thickness of about 0.01 mm., dries in less than five minutes to form a film having the properties of (i) being hydrophobic, as determined by scrubbing the film using light finger pressure with a saline-soaked gauze for at least 40 scrubs with no observable removal of film or loss of iodine color, and (ii) being capable of elongating at least about 5% before breaking.
