摘要:
The use of stabilized chlorine dioxide or chlorine dioxide in aqueous solution as a composition to reduce or prevent plaque formation and treatment of oral diseases ecologically plaque dependent, such as gingivitis and periodontitis, is disclosed. Preferred concentrations are in the range of 0.005% to 0.2% and the chlorine dioxide may be in the form of a rinse, a wash, a soak or a dentifrice.
摘要:
An anti-microbial composition comprises an aqueous solution of a germicidal polymeric nitrogen compound and an oxidizing agent which potentiates the activity of the compound. The polymeric nitrogen compound includes a germicidal quaternary ammonium compound or a polyguanide compound. The oxidizing agent has a standard reduction potential between 0.85 and 2.0 volts, is soluble in water, non-toxic and enhances the activity germicidal of the nitrogen polymer at low concentrations. Suitable oxidizing agents include halogen oxides, oxyhalogens, halogens, and inorganic and organic peroxides.
摘要:
An anti-microbial composition is provided comprising an aqueous solution of an oxyhalogen compound and a polymeric germicide. The oxyhalogen compound is preferably stabilized chlorine dioxide and the polymeric germicide is preferably a quaternary ammonium compound such as a copolymer of at least one difunctional tertiary amine and a dihalo organic compound such as 1,4-dihalo-2-butene, a copolymer of at least one difunctional tertiary amine, at least one monofunctional tertiary amine and a dihalo organic compound such as 1,4-dihalo-2-butene, or a polyguanide such as hydrochloride salt of poly(hexamethylene biguanide). The anti-microbial composition thus formed is used for the treatment of soft contact lenses to disinfect the same with an optimum effect while minimizing the irritant possibilities thereof and also minimizing absorption of the composition into the porous and hydrophilic surfaces of soft contact lenses such that there is a minimal release of absorbed substances after treatment.
摘要:
An aqueous solution suitable for dissipating, at a controlled rate, available iodine contained in an iodophor is disclosed. The aqueous dissipating solution contains sorbic acid or soluble salts thereof and ethylenediaminetetraacetic acid or soluble salts thereof. Preferably, the dissipating solution also contains an ammonium, alkali metal, or alkaline earth metal salt of a boron oxyacid. Also disclosed are techniques for sterilizing contact lenses and sterile solutions, suitable for maintaining sterility of a previously sterilized object, comprising admixtures of the dissipating solutions with iodophor solutions.
摘要:
An aqueous, antiseptic, iodophor solution is provided containing iodine, a water soluble iodide salt or hydriotic acid, polyvinyl alcohol and boric acid. The iodophor solution may be employed to sterilize a broad range of animate and inanimate objects, including contact lenses. Additionally, the iodophor solution, or similar iodophor solutions which do not contain boric acid, may be employed in visual temperature sensing devices. The visual temperature sensing devices comprise a transparent vessel containing the iodophor solution. Also disclosed is an aqueous solution for dissipating, at a controlled rate, available iodine contained in an iodophor. The aqueous dissipating solution contains sorbic acid or soluble salts thereof and ethylenediaminetetraacetic acid or soluble salts thereof.
摘要:
Soft, hydrophilic acrylate and methacrylate copolymer materials are sterilized by immersing them in a solution containing small, but effective amounts of a material which releases active halogen in solution, but is non-damaging to the eye in concentrations effective for sterilization. A particularly effective material is chlorinated trisodium phosphate. The concentrataion of the sterilant material should be such that it releases halogen in amounts of from about 2 parts per million to 250 parts per million. The technique is particularly useful for sterilization of soft, hydrophilic acrylate and methacrylate contact lenses.
