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 improved and novel animal litter is described utilizing alumina, aluminosilicates or coal residues as the substrate intimately mixed with monomers containing acid functionalities which are polymerized in-situ. The resulting mixture is then extruded into pellets of any size or shape. Animal litter pellets prepared by this invention have vastly improved water adsorption properties, deodorizing capacity, and they do not have to be cured at high temperatures.
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 inexpensive, easily available, and convenient method of treating or preventing a virus infection is provided. The present invention relates to a method for the treatment or prevention of virus infections using polybiguanide-based compounds administering a therapeutically effective amount of a compound or a pharmaceutically acceptable salt thereof The invention relies on the unique biochemical reaction in which polybiguanide-based compounds interfere with the spread of virus within or between organisms. The compositions and formulations described in the present invention are effective means to reduce the infectivity of the human immunodeficiency virus type 1 (HIV-1), and human herpes simplex viruses, and also to kill the causative organisms of many other sexually transmitted diseases (STDs).

摘要:
A controlled release biocidal salt of a first component comprises a cation of a Nα—(C1-C22)alkanoyl di-basic amino acid alkyl(C1-C22)ester cationic biocidal molecule and a second component comprising an anion of a monomeric anionic molecule having insignificant biocidal activity. The salt is characterized such that when the salt is exposed to an aqueous medium, the salt partially dissolves thereby releasing biocidal ions in an amount sufficient to exceed the MIC or MBC of a target bacteria being controlled, and further characterized as leaving a residual reservoir of undissolved salt capable of releasing more biocidal ions as the salt is consumed or otherwise removed from the environment encompassing the target bacteria. The preferred cationic biocidal molecule comprises Nα-lauroyl-L-arginine ethyl ester (“LAE”).
