WO0035276

Disclosed are cyanoacrylate compositions comprising a compatible antimicrobial agent and, in particular, a compatible iodine containing antimicrobial agent. These compositions provide for in situ formation of an antimicrobial polymeric cyanoacrylate film of mammalian skin.

US4650826

This invention relates to stabilized adhesives, to which silyl esters are added for stabilization.

US2706701

This invention relates to an improved for preparing a dry powdered adduct of iodine and polymeric 1-vinyl-2-pyrrolidone (hereinafter called polyvinylpyrrolidone) whereby a stable composition is formed which is readily available and germicidally and bactericidally active form which is essentially non-toxic to warm-blooded animals.

Povidone Iodine or polyvinyl pyrrolidone-iodine, commonly abbreviated as PVP-I was discovered by American scientists H. A. Shelanski and M. V. Shelanski. PVP- I was introduced to the pharmaceutical market as an antiseptic agent in the 1950’s and is found to be more effective than other iodine formulations and was less toxic

US2900305

This invention relates to the preparation of an adduct of iodine and polymeric 1-vinyl-2-pyrrolidone (hereinafter referred to as polyvinylpyrrolidone) whereby there is fomred a composition which is readily soluble in water to form a stable solution and which provides iodine in readily available germicidally and bactericidally active form which is essentially non-toxic to warm-blooded animals.

US2826532

This invention relates to a process of stabilizing a dry powered adduct of iodine and polymeric 1-vinyl-2-pyrrolidone (hereinafter referred to as polyvinyl pyrrolidone) whereby a stable composition is obtained which when dissolved in water will not change its pH and maintain a constant available iodine content.

US5684042

Disclosed are cyanoacrylate compositions comprising a compatible antimicrobial agent and, in particular, a compatible iodine containing antimicrobial agent. These compositions provide for in situ formation of an antimicrobial polymeric cyanoacrylate film on mammalian skin.

US5480935

Alkyl cyanoacrylate compositions comprising at least one alkyl cyanoacrylate, a biocompatible plasticizer (preferably dioctyl phthalate), and SO.sub.2 as an artionic polymerization inhibitor are provided. These compositions are suitable for topical application to human skin.

US4978527

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.
