摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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 uniform quantities of an aqueous bleach concentrate to bleaching locus such as a washing machine. The tablets can be made from the encapsulated bleach or from a powder mixture of a particulate, granulated or powdered unencapsulated source of active oxidizing bleach and an encapsulated source of active oxidizing bleach by forming the powder mixture into a desired shape. The presence of the encapsulate in the solid with the powder reduces the tendency of the solid to absorb water which can be wicked through the solid to pass water through the solid into adjacent solids. Substantial proportions of absorbed water can cause the tablets to crack, crumble and to periodically dispense uneven, substantially large and undesirable concentrations of active bleach into a wash or bleach cycle.
