Abstract: An aqueous, heat and cold stable, non-alcoholic or slightly-alcoholic microemulsion based antimicrobial mouthwash composition with improved antimicrobial efficacy. The composition comprises a unique water-soluble matrix composite, at least one water-immiscible or water-insoluble antimicrobial agent, and optionally, a preservative or preservative system, a weak carboxylic acid, a coloring agent and other additives. Examples of antimicrobial agents include menthol, thymol, eucalyptol and/or methyl salicylate. A process for preparing the oral care composition is also disclosed.

Abstract: Oral care compositions containing an oral care ingredient and a thickening agent, wherein the thickening agent comprises a strongly swellable, lightly to moderately crosslinked polyvinyl pyrrolidone. The polyvinyl pyrrolidone thickening agent is characterized by an aqueous gel volume of about 15 to 150 ml/g and a Brookfield viscosity of at least 10,000 cps for a 5% aqueous solution at 25° C.

Abstract: Disclosed herein is a water-based, peroxide-stabilized, abrasive tooth whitening composition comprising: (i) a peroxide-polymer complex comprising (a) a peroxide component or a peroxide generating component; and (b) a vinyl lactam based polymer; (ii) coated abrasive particles; and one or more orally acceptable carriers. This application also provides methods for whitening the tooth surfaces by contacting with the compositions. Additionally disclosed is a process for preparing the compositions.

Abstract: A process for preparing a concentrated detergent composition useful in automatic machine dishwashers comprising preparing a dry mixture of a thickening polymer and a sodium trimetaphosphate builder, then adding the dry blend to water and subsequently adding a potassium hydroxide base to form a homogeneous solution. Sodium silicate and optional ingredients are then added to the process. Compositions resulting from the process contain a K+/Na+ weight ratio of greater than about 0.5 to about 1 and a viscosity of from 1,800 to about 3,500 cps.

Abstract: A homogeneous liquid detergent composition comprising sodium trimetaphosphate, potassium hydroxide and an alkali metal silicate, the composition being substantially free of added potassium salts with a K/Na weight ratio of less than 1 and preferably in a gel form.

Abstract: Liquid light duty cleaning compositions comprise an organic base (such as amines), a zinc salt (such as zinc halides or zinc citrate), and a complexing agent (such as EDTA). The compositions are useful in cleaning both at full strength and when diluted and do not cause staining of treated aluminum utensils.
