An improved cleaning composition adapted to clean a variety of hard surfaces. The improved cleaning composition includes a cationic biocide that includes biguanide compounds and/or quats.

Cleaning composition

An improved cleaning composition and method adapted to clean a variety of hard surfaces. The improved cleaning composition and method includes the use of a cationic biocide that includes biguanide compounds and/or quats.

The invention provides an improved, liquid aqueous hard surface cleaner containing a fluoropolymer having a molecular weight of no less than 5,000, further containing preferably a nonionic surfactant, optionally, a quaternary ammonium compound, a chelating agent/buffer and water to provide enhanced cleaning of hard surfaces, especially vitreous surfaces, in which the thus cleaned surface is rendered soil and stain repellent.

Hard surface cleaner with improved stain repellency comprising a fluoropolymer and a quaternary ammonium surfactant

The present invention provides an improved antimicrobial composition which includes at least one quaternary ammonium compound and nerolidol. The nerolidol component of the composition provides enhanced antimicrobial efficacy, even when used in small amounts. Further, the nerolidol component provides such enhanced antimicrobial efficacy that the quaternary ammonium compound may be used in reduced amounts as compared to the amounts used for antimicrobial effect in prior formulations. The enhanced antimicrobial composition of the present invention is especially useful in cleaning or disinfecting applications, such as the cleaning of hard surfaces.

Enhanced antimicrobial composition

Cleaning wipes

A powdered abrasive cleanser that exhibits superior soil removal properties and surface safety is provided. The cleanser includes a surfactant, an optional source of active chlorine, a borax pentahydrate compound that is preferably sodium tetraborate pentahydrate, and optionally an alkaline detergent builder and/or calcium carbonate.

Powdered abrasive cleanser containing borax pentahydrate

A concentrated, dilutable cleaning composition is provided which comprises a microemulsion comprising an oil phase of which the 'oil' is a nonionic surfactant, a predominant aqueous continuous phase, a polar organic solvent coupling agent, and a combination of surfactants different from the surfactant oil phase as the dispersing agent facilitating formation of said microemulsion, the cleaning composition dilutable with water for use as an all purpose cleaner and characterized by exhibiting the feature of blooming upon such dilution even in the absence of a lipophilic oil (or solvent). The blooming phenomenon is associated with the formation of a liquid crystal dispersion, which liquid crystal state is found to greatly enhance the cleaning effectiveness of the composition. In one aspect of the invention, one of the dispersing agent surfactants is a cationic surfactant which may be a quaternary ammonium compound capable of imparting an antimicrobial effect to the composition.

Microemulsion dilutable cleaner

Powdered abrasive cleanser comprising calcium carbonate and borax

The invention provides a concentrated, dilutable cleaning composition which comprises a novel microemulsion comprising a nonionic surfactant oil phase, a predominant, aqueous continuous phase, a polar organic solvent coupling agent, and a combination of surfactants different from the surfactant oil phase as the dispersing agent facilitating formation of the microemulsion.

A thickened, buffered aqueous acidic cleaning composition suitable for removing mineral deposits is provided. In one embodiment, the composition comprises a weak acid and its conjugate base wherein the weak acid has a pK.sub.a of approximately 2 to 3.5 and where the composition has a pH of approximately 2 to 3.5. Organic acids, such as citric acid, are particularly suited. The addition of a thickening system comprising cetyl trimethyl ammonium chloride and sodium xylene sulfonate or alkyl diphenylether sulfonate produces a viscoelastic composition in which the viscosity can be controlled by the level and/or ratio of the surfactant/counterion. Suitable stable adjuncts including fragrances, dyes, organic solvents, disinfectants, and bleaches can be added to the composition.
