Abstract:
The present invention relates to a method of pre-rinsing laundry and treating other surfaces employing a composition that can kill bedbug eggs. The composition includes an anionic compound and is at pH just above neutral, e.g., about 7 to about 9.
Abstract:
Compositions and methods for improved cleaning using neutral cleaners are disclosed. In particular, neutral pH cleaning compositions according to the invention employ a synergistic combination of water insoluble surfactants and an anionic hydrotropes capable of forming a stable, low-foaming solution. The neutral cleaning solutions provide significant benefits over water insoluble microemulsions traditionally used for neutral cleaning compositions and provide at least equivalent cleaning efficacy as non-neutral cleaning compositions.
Abstract:
According to the invention, the compositions and methods provide for the complete removal of synthetic glues or adhesives from a plurality of surfaces through the use of amide solvents in combination with surfactants, chelants, acidulants and/or additional bottle wash additives. Beneficially, the compositions and methods are suitable for use at lower temperatures, including below 35° C., and lower pH conditions, including from 5 to 10, from 6 to 9, and from 6 to 8, in comparison to conventional caustic-based adhesive removal compositions.
Abstract:
Methods of cleaning sugar evaporators with a cleaning composition comprising a sugar or sugar-moiety containing compound are disclosed. The methods are capable of improved scale and fouling removal from treated surfaces, including scale containing calcium oxalate, calcium dihydrogen phosphate, silica and/or other components from sugar evaporators. The methods reduce time required for scale removal without the need for highly alkaline cleaning compositions, elevated temperatures and/or mechanical force applied to the scale.
Abstract:
A device for in-situ production of caustic and increasing alkalinity of a detergent and methods for increasing alkalinity of a detergent are disclosed. In particular, in situ electrochemical conversion of bicarbonate, sesquicarbonate or carbonate sources into caustic provides a safe means for increasing alkalinity of a detergent for a variety of cleaning applications. The invention further discloses methods for cleaning using the electrochemically enhanced detergent according to the invention.
Abstract:
Peroxycarboxylic acid compositions having reduced hydrogen peroxide content are generated according to the invention, having enhanced antimicrobial efficacy. Simultaneously, a stable hydrogen peroxide and active oxygen coordinating compound complex is generated and has utility as a recycled bleaching component. In particular, methods of using an active oxygen coordinating compound to selectively and non-destructively remove hydrogen peroxide are provided. Preferred active oxygen coordinating compounds suitable for use with the peroxycarboxylic acid compositions include nitrogen-containing compounds, preferably urea, urea copolymers and/or derivatives, PVP, PVP copolymers and/or derivatives, and/or inorganic carbonates.
Abstract:
A method of creating a protective coating on an alkali metal hydroxide-containing solid is provided. The method includes providing carbon dioxide to an alkali metal hydroxide-containing solid and allowing the alkali metal hydroxide and carbon dioxide to react thereby forming a carbonate or bicarbonate-containing layer on the exterior of the solid wherein the carbonate or bicarbonate-containing layer is non-hygroscopic and water soluble, and wherein greater than 80% of the hydroxide in the hydroxide-containing solid does not react with the carbon dioxide, and further wherein the alkali metal hydroxide-containing solid is substantially free of lithium hydroxide. A method of testing for the presence of carbonate-containing coating on an alkali metal hydroxide containing solid is also provided. The method includes exposing the coated solid to 95 weight percent ethanol, collecting the ethanol effluent and testing the effluent for alkali metal hydroxide. A suitably coated solid does not have dissolved alkali metal hydroxide in the ethanol effluent or is substantially free of alkali metal hydroxide.

Abstract:
A flooring is disclosed including a substrate having a coating composition thereon, the coating composition comprising a hardenable film-former and at least 0.5 weight percent of an oxidizing agent sufficient to decolorize a stain on the film-former is disclosed, wherein the oxidizing agent comprises hydrogen peroxide, hypochlorite, and organo-chlorine bleaches and will at least partially decolorize a plurality of stains when applied to the hardened coating, allowed to stand for one hour at room temperature, and evaluated by visual observation of the stain under average overhead fluorescent illumination. The oxidizing agent is not consumed as a catalyst or initiator to polymerize or otherwise cause a reaction in the floor coating before it is applied and before it has hardened. A coating composition of the invention may include from about 0.8 to about 5 weight percent oxidizing agent and the film-former forms a hardened film resistant to rinsing with tap water.
