Disclosed are devices, systems, and methods for producing broad spectrum disinfectants, sanitizers, cleaner and deodorizers using chlorine dioxide compositions, and more particularly, to methods for producing chlorine dioxide compositions having improved long term stability by the proper choice of pH and through the careful choice of other product formula ingredients.

Devices, systems and methods of making and using chlorine dioxide based formulation with improved stability

Chlorine dioxide based formulation with improved stability

A cleaning composition with a limited number of natural ingredients contains alkyl polyglucoside, a 2-hydroxylcarboxylic acid, and a fragrance containing lemon oil or d-limonene. The cleaning composition optionally has a small amount of dye, colorant, and preservative. The cleaning composition can be used to clean hard surfaces and cleans as well or better than commercial compositions containing synthetically derived cleaning agents.

Acidic cleaning compositions

The present invention relates to cleaning compositions containing C8-C10 alkylpolyglucosides which have low filming and streaking when combined with C2-C4 alcohols. The cleaning compositions can optionally comprise dyes, builders, fatty acids, fragrances, colorants, glycerol, anti-foaming agents, and preservatives.

The cleaning composition can be used to clean hard surfaces and cleans as well or better than commercial compositions containing synthetically derived cleaning agents.

Cleaning compositions containing C8-C10 alkylpolyglucosides, have low filming and streaking when combined with C2-C4 alcohols and propylene glycol ethers. The low filming and streaking occurs even in the presence of quaternary ammonium biocides.

Low residue cleaning solution comprising a C8-C10 alkylpolyglucoside

Cleaning wipes containing antimicrobial quaternary ammonium compounds and alkylpolyglucosides, especially C8-C10 alkylpolyglucosides, have low filming and streaking when combined with C2-C4 alcohols and glycol ethers having a vapor pressure between 0.1 and 2.0 mm Hg at 20&#xb0; C.

Antimicrobial hard surface cleaner comprising an ethoxylated quaternary ammonium surfactant

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.

Acidic aqueous cleaning compositions

A bleaching product and a method of removing soils from fabrics by contacting the fabrics in an aqueous wash solution with a product comprising a peracid precursor, a source of hydrogen peroxide and a source for delayed release of an acid into the wash solution to initially permit effective in situ formation of peracid, the acid thereafter reducing the pH of the wash solution for enhancing bleach performance of the peracid. The source of the acid may be included in the bleaching product, for example, as an acid of delayed solubility, an acid coated with a low solubility agent or an acid generating species, or independent of the bleaching product. The acid source is selected to be compatible with the peracid or precursor and adjuncts. The method for removing soils thus comprises contacting the fabrics in an aqeuous solution with a peracid precursor and a source of hydrogen peroxide, initially raising the pH of the solution for effective in situ formation of peracid and then reducing the pH for enhancing bleach performance of the peracid.

Method and product for enhanced bleaching with in situ peracid formation

A dry cleaning system particularly suited for employing supercritical CO.sub.2 as the cleaning fluid consisting of a sealable cleaning vessel containing a rotatable drum adapted for holding soiled substrate, a cleaning fluid storage vessel, and a gas vaporizer vessel for recycling used cleaning fluid is provided. The drum is magnetically coupled to a motor so that it can be rotated during the cleaning process. The system is adapted for automation which permits increased energy efficiency as the heating and cooling effect associated with CO.sub.2 gas condensation and expansion can be channeled to heat and cool various parts of the system.

Liquid/supercritical carbon dioxide/dry cleaning system

The invention provides a cleaning method in which a solvent such as densified carbon dioxide can be used for rapid and efficient cleaning, but with decreased damage to solid components such as buttons. The method comprises contacting a substrate to be cleaned with a first fluid, removing the first fluid from contact with the substrate while replacing with a second fluid, and recovering the substrate substantially free of the first and second fluids and from the contaminant. The first fluid is a densified gas while the second fluid is a compressed gas. A preferred embodiment of the method includes the use of a pretreatment designed for compatibility with the densified first fluid.
