Chlorine dioxide disinfecting cloth
The invention relates to highly effective disinfecting or sterilising cloths with chlorine dioxide as the main active ingredient. For this, the chlorine dioxide is only generated shortly before use by bringing a cloth impregnated with a chlorite or chlorate salt in contact with a clearly defined amount of a suitable activation agent that is fluid or dissolved or admixed in a fluid, and prepackaged as a single dose, for the generation of chlorine dioxide. In a preferred embodiment, the impregnated cloth and the activation fluid are packaged in a common packaging unit and the activation occurs by breaking through a barrier separating the cloth or the cloths and the activation fluid. In a further preferred embodiment, the packaging is a moulded part having two packaging spaces separated from one another by removable barriers, which can be converted into a moulded part with only one chamber via simple pressure in one direction. The activation fluid or the disinfecting cloth can contain further substances, such as the pH-value-controlling substances, surfactants, guanidine derivatives, aldehydes, phenoxyethanols, phosphate esters, alcohols, sulfoxides, etc. Preferably, the disinfecting cloth according to the invention is used for disinfecting and/or sterilising medical instruments and/or medical products and/or surfaces.
DETERGENT COMPOSITIONS
The invention provides a detergent composition for the non-oxidative laundering of fabric stains, the composition comprising: (a) from 0.1 to 10% (by weight based on the total weight of the composition) of ethylenediamine-N,N′-bis-(2-hydroxyphenyl) acetic acid (EDDHA) and/or salts thereof, and (b) from 3 to 80% (by weight based on the total weight of the composition) of one or more detersive surfactants.
CLEANING COMPOSITIONS COMPRISING COPOLYMERS AND THEIR USE
Cleaning compositions e.g. containing one or more copolymers comprising structural units a) derived from one or more monomers comprising a sulfonic acid group or a sulfonate group, and structural units b) derived from one or more monomers comprising a carboxylic acid group or a carboxylate group and structural units c) derived from one or more cationic monomers are disclosed.
The cleaning compositions are e.g. suited to be used for the treatment of hard surfaces, for easier next time cleaning of hard surfaces and for preventing the build-up of limescale on hard surfaces.
COMPOSITE GLASS COMPOSITION FOR WASHING AND CLEANING AND METHOD FOR PRODUCING COMPOSITE GLASS POWDER USING THE SAME
Disclosed are a composite glass composition for washing and cleaning and a method for producing composite glass powder using the same, in which a silicate-based glass composition containing an alkali oxide for activating water into alkaline water and a bleaching agent having bleaching performance are mixed or coated. Accordingly, since the silicate-based glass composition containing an alkali oxide can ionize water in place of a surfactant contained in existing synthetic detergents, washing and cleaning capacity equivalent to or greater than existing synthetic detergents can be secured with alkaline water ionized from water.
Precursor polyelectrolyte complex compositions in dual chamber dispensing system
The invention relates to compositions and methods of treatment employing compositions comprising polyelectrolyte complexes. The compositions include a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge and a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge. The total polyelectrolyte concentration of the first solution is at least 110 millimolar. The composition is free of coacervates, precipitates, latex particles, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte. The composition may be a concentrate, to be diluted prior to use to treat a surface.
BLEACH CATALYST
A bleach catalyst suitable for use in automatic dishwashing comprising a mixed metal oxide.
POWDERS AND GRANULES AND PROCESS FOR MAKING SUCH POWDERS AND GRANULES
The present invention is directed towards a process for making a powder or granule containing (A) at least one alkali metal salt of citric acid, and at least one additive selected from (B) at least one (co)polymer containing carboxylic acid groups, partially neutralized with alkali, in a weight ratio of (A):(B) of from 5:1 up to 100:1, wherein said powder or granule contains at least 75% by weight of citrate (A), said process comprising the steps of (a) mixing the at least one alkali metal salt of citric acid (A) and the at least one (co)polymer (B) in the presence of water, (b) removing most of said water by spray-drying or spray granulation using a gas with an inlet temperature of at least 125° C.
AUTOMATIC DISHWASHING COMPOSITION COMPRISING AT LEAST ONE IMIDAZOLE-BASED COMPOUND
Described herein is an automatic dishwashing (ADW) composition including as component (A) at least one imidazole-based compound selected from the group consisting of unsubstituted or at least monosubstituted imidazole and benzimidazole. The automatic dishwashing composition may include further components, such as polyakylene imines (component (B)), at least one silicate (component (C)) and/or at least one chelating agent (component (D)). Also described herein is a process for cleaning dishware using said ADW composition as well as a method of using said ADW composition, for example, to reduce any corrosion on the items to be dishwashed (dishware). Also described herein is a method of using at least one imidazole-based compound according to component (A) as a corrosion inhibitor in automatic dishwashing processes.
Compositions and Methods for Use in Surface Decontamination
The disclosure provides compositions and methods for making a colorized solution of an aqueous disinfectant that is both stable in bulk solution and will fade to clear within a predetermined period of time after being applied to a surface, for example as a spray or film. The compositions and methods described here allow an end user to visualize both the extent of coverage and the duration of contact of the disinfectant with the surface, thereby providing more efficient disinfection of the surface.
Electrolytic system for automatic dishwashing
A method of automatic dishwashing of dishware, including electrolytically generating a bleaching species, washing the dishware with a composition comprising the bleaching species, and washing the dishware with a composition including an enzyme. The invention also includes an automatic dishwasher including a wash tank, an electrochemical cell, and a first reservoir containing a composition including an enzyme, wherein the electrochemical cell contains a solution including an alkali metal chloride salt, wherein the dishwasher is configured to electrolyze the solution, and to dose the electrolyzed solution into the wash tank before dosing the composition including the enzyme into the wash tank. The invention also includes a kit for use in the method of automatic dishwashing of dishware.
