  • Patent number: 9301928
    Abstract: The disclosed conformable coating provides a highly durable and resilient film useful for protecting and repairing surfaces such as skin and mucous membranes. The coating comprises 0.1% to 65% wt. of a polymerized cyanoacrylate monomer and at least 35% wt. of an elastomer phase. The conformable coating composition comprises a polymerizable cyanoacrylate monomer, an elastomer, and a volatile liquid. The cyanoacrylate monomer is 0.1 to 65% wt. of the nonvolatile portion, the elastomer in an elastomer phase is at least 35% wt. of the nonvolatile portion, and the volatile liquid is at least 40% wt. of the total composition.

  • Patent number: 5308180
    Abstract: A liquid applicator is provided which is particularly useful in applying preoperative surgical scrubs or paints to skin. The article is provided with an inner layer of flexible porous material and an outer layer of open cell foam sponge material. The flexible, porous layer regulates the flow of liquid therethrough to provide acceptable wetting of the foam sponge while preventing dripping therefrom. The applicator includes a means of maintaining atmospheric pressure within the applicator while the liquid is being dispersed.

  • Patent number: 4584192
    Abstract: A film-forming composition containing a broad spectrum antimicrobial as an antimicrobial agent. The composition forms a film which is a substantially fluid-resistant, substantially tack-free, flexible film which adheres to skin and releases the antimicrobial agent to skin. A method of using the film-forming composition is also disclosed.

  • Patent number: 4542012
    Abstract: A dermatologically acceptable, film-forming composition which comprises a film-forming polymer and, as a broad spectrum antimicrobial agent, iodine which forms a complex with the film-forming polymer. The compositions when applied to skin from a fugitive solvent form a substantially water-insoluble, tack-free, flexible film which adheres to skin, releases the antimicrobial agent when the film is in contact with skin, and exhibits an elongation of at least about 150%. A method of using the composition is also described.
