摘要:
A warewashing detergent composition is provided according to the invention. The warewashing detergent composition includes a cleaning agent, an alkaline source, and a corrosion inhibitor. The cleaning agent comprises a detersive amount of a surfactant. The alkaline source is provided in an amount effective to provide a use composition having a pH of at least about 8. The corrosion inhibitor includes a source of aluminum ion and a source of zinc ion. The relative amounts of the source of zinc ion and the source of aluminum ion can be controlled to reduce visible filming when the warewashing detergent composition is used in the presence of hard water. Methods for using and manufacturing a warewashing detergent composition are provided.

Aqueous bleach solutions can be made by directing a spray of water onto a bulk or shaped solid (brick, tablet, block, etc.) comprising a continuous solid phase of an encapsulated source of an active halogen bleach or a solid comprising a source of an oxidizing active halogen bleach, and an encapsulated oxidizing halogen bleach source. Such shaped solids can be used to dispense an aqueous bleach concentrate to bleaching locus such as a washing machine.

Solid block alkaline detergent compositions are disclosed comprising a source of alkalinity, and other detergent additives including sequestrants. The solid block detergents of the invention used a mixed inorganic and organic sequestrant composition that successfully softens service water used in manufacturing aqueous detergents from the composition, but also obtains substantially improved organic soil removal on dishware or flatware. The solid block detergents of the invention comprise large masses of the chemical ingredients having a weight of greater than about 500 grams in a solid block product format that is typically dispensed using a spray on water dispenser that creates an aqueous concentrate that is used in a washing machine.

The invention relates to a highly alkaline or mildly alkaline detergent composition having enhanced cleaning properties. The detergent combines a source of alkalinity and a blend of nonionic surfactants that enhances cleaning starchy soils. The blend of nonionic surfactants preferably includes an alkyl polyglycoside surfactant and a silicon surfactant having a hydrophobic silicon group and a pendant hydrophilic group. Preferably, the blend of nonionic surfactants includes a surfactant having a hydrophobic group and an ethylene oxide residue containing group and a polymer additive. A method for removing soil from an article is provided.

Hard floor finishes and other stubborn soils can be removed using an aqueous dispersion of an alkylene glycol phenyl ether solvent combined with an ether alcohol solvent/coupler. Each component is used at a concentration that result in the creation of a visible dispersed appearance of the aqueous dilute use solutions. We have found that the alkylene glycol phenyl ether, in combination with at least one ether alcohol coupler or solvent, interacts with the aqueous medium to surprisingly provide enhanced cleaning performances. Hard to remove soils such as highly crosslinked urethanes and acrylic materials can be solubilized and removed by the alcohol solvent dispersions of the invention. We have found that the alkylene phenyl ether solvent requires a specific coupler cosolvent for activity. Such activity can be enhanced by the presence of a second coupler cosolvent and the use of a specific class of nonionic surfactant materials.

The dimensionally stable alkaline solid block warewashing detergent uses an E-form binder forming a solid comprising a sodium carbonate source of alkalinity, a metal corrosion protecting alkali metal silicate composition, a sequestrant, a surfactant package and other optional material. The solid block is dimensionally stable and highly effective in removing soil from the surfaces of dishware in the institutional and industrial environment. The E-form hydrate comprises an organic phosphonate and a hydrated carbonate.

The invention relates to microemulsion compositions containing water, a mixture of nonionic surfactants, and oil. The microemulsion provides for the removal of hydrophobic particularly oily soils from a variety of substrates. The compositions can be used for hard surface, laundry cleaning, hand washing, and car washing. Typical hydrophobic soils are oily based soils derived from petroleum oils or natural fats and oils also containing a significant proportion of particulate soils such as carbon, common dirt and other non-water soluble typically hydrophobic soil particulate. The microemulsion composition can include a splitting agent such as an amphoteric surfactant for controlling the conditions under which the microemulsion will split.

A highly alkaline or mildly alkaline detergent composition having enhanced cleaning properties is provided. The detergent combines a source of alkalinity and a blend of nonionic surfactants that enhances cleaning waxy-fatty soils.
摘要:
A method for cleaning plasticware wherein the rinse cycle employs a rinse aid composition requires lower concentration of conventional hydrocarbon surfactants, exhibits adequate sheeting on the plasticware and acceptable drying time which prior rinse aids have failed to provide without special handling. The compositions contain hydrocarbon surfactants and a combination of a fluorinated hydrocarbon surfactant and a polyalkylene oxide-modified polydimethylsiloxane surfactant. The composition may be formulated as a solid or liquid suitable for dilution to form an aqueous rinse used to contact the plasticware in a warewashing machine.
