Abstract: An aqueous carbon dioxide-absorbent solution comprising at least one alkanolamine and at least one quaternary ammonium salt is disclosed. A method of recovering carbon dioxide from a carbon dioxide-containing gaseous mixture and a method of reducing metal corrosion in an alkanolamine-based exhaust gas treating process are also disclosed.

Abstract: The present invention is a preservative formulation which includes a combination of at least two (2) compounds having bactericidal and/or fungicidal properties wherein the at least two (2) compounds is selected from the group consisting of methylisothiazolinone/piroctone olamine; caprylyl glycol/dehydroacetic acid; undecanol/dehydroacetic acid and lauryl alcohol/sorbic acid. The invention also includes preparations including such combination as well as a method of using the combination to reduce bacterial and fungal load of preparations.

Abstract: The invention provides a method for preventing discoloration of pyrithione-containing materials, in particular plastic materials or other material such as paints, coatings, adhesives or textiles which are exposed to an outdoor environment. The method is likewise suited for preventing discoloration of other pyrithione-containing materials such as personal care compositions like shampoos. A discoloration inhibitor that includes dehydroacetic acid or a salt thereof is added to the pyrithione-containing material. The discoloration is prevented without the addition of a cyclic organic phosphoric acid ester or an organic phosphite. Use of the discoloration inhibitor does not interfere with the antimicrobial effect of the pyrithione.

Abstract: The present invention relates to a method for imparting antibiotic activity to a surface of a solid substrate by exposing a solid substrate composition to conditions suitable for covalent grafting and thermal polymerization of the substrate.

Abstract: The present invention relates to antimicrobial compositions including an aromatic dialdehyde and a quaternary ammonium compound wherein the aromatic dialdehyde is orthophthalaldehyde, isophthalaldehyde, terephthalaldehyde, or combinations thereof; the quaternary ammonium compound is didecyldimethylammonium bicarbonate, didecyldimethylammonium carbonate, or didecyldimethylammonium bicarbonate/carbonate; and the ratio of aromatic dialdehyde to quaternary ammonium compound is from about 1:1.2 to about 1:2. The invention also relates to methods of treating surfaces using the antimicrobial compositions of the invention.

Abstract: A plastic material having an antimicrobial characteristic and the method for making the plastic material is provided. The method includes blending and/or extruding a polymeric composition in a process which includes a temperature of at least about 170° C. The method also includes adding an antimicrobial component to the polymeric composition prior to or during the blending and/or extruding. The antimicrobial component includes a salt of a dehydroacetic acid (DHA) in an amount sufficient to provide the resulting plastic material with an effective antimicrobial characteristic. The antimicrobial component including a salt of DHA is stable at temperatures required for processing polymeric compositions.

Abstract: The present invention relates to antimicrobial compositions including an aromatic dialdehyde and a quaternary ammonium compound wherein the aromatic dialdehyde is orthophthalaldehyde, isophthalaldehyde, terephthalaldehyde, or combinations thereof, and the ratio of aromatic dialdehyde to quaternary ammonium compound is from about 10:1 to about 1:5. The invention also relates to methods of treating surfaces using the antimicrobial compositions of the invention.

Abstract: The present inventors have discovered that electrolytes, such as the tetrasodium salt of ethylenediaminetetraacetic acid (EDTA), reduce the ocular irritation and increase the disinfecting and sanitizing efficacy of compositions containing quaternary ammonium compounds and/or amines. As a result, concentrated solutions containing quaternary ammonium compounds and/or amines of the present invention have low, if any, ocular irritation. Furthermore, use dilutions of the concentrated solutions of the present invention include ingredients which are approved by the U.S. EPA for use on indirect food contact surfaces, unlike disinfecting and sanitizing compositions containing imidazoline compounds. Additionally, the use dilutions exhibit superior efficacy against gram negative and positive bacteria compared to similar compositions which do not contain the electrolyte and remain effective in hard water. The present invention is a concentrate, such as a sanitizing and disinfecting concentrate, comprising from about 0.

Abstract: The present invention provides compositions comprising quaternary ammonium compounds and dendritic polymers, which can be applied to hard surfaces. The compositions form transparent films and do not cause any unsightly residue on the surface to which is applied. The compositions provide immediate antimicrobial efficacy upon application as well as residual antimicrobial activity, especially broad-spectrum efficacy over prolonged periods, and may be used at low levels to prevent toxicity problems to the user. The film is water-soluble, easily removed completely with warm water, and does not require special techniques or harsh chemical treatments to effect its complete removal. The present invention also provides a method of disinfecting a substrate, preferably a hard surface, comprising applying a disinfecting composition of the invention to the substrate.

Abstract: An aqueous antimicrobial liquid cleaning formulation comprising about 0.2 to 4 parts of a cationic quaternary ammonium compound; about 2 to 10 parts of one or more nonionic surfactants; and about 1 to 10 parts of a polyfunctional alcohol wherein the weight ratio of nonionic surfactant and polyol to cationic surfactant is at least about 4:1 to about 28:1.
