The invention relates to rinse aid compositions useful in warewashing, that provide sanitizing properties and stain control. The rinse aids of the invention provide a highly active available chlorine source which is incorporated into solid systems containing sheeting agents. The chlorine source is sufficiently stable to permit manufacture, storage, distribution, sale and consumption without loss of substantial proportions of active chlorine, while allowing for a broad selection of surfactants.

Chlorinated solid rinse aid

An air freshener device (200) has a cartridge (100). The cartridge (100) has a housing (101) having a tray (102). A first fragrance (105) is in a first cavity (103) and a second fragrance (106) is in a second cavity (104). A fragrance diffuser (130) is operatively connected to the tray (102) and positioned over the compartments of the tray. A removable cover is operatively connected to the tray to seal the open tops of the cavities. A battery cover (116) has a first side operatively connected to the housing and a second side connected to the housing after a battery is enclosed in the cover.

A solid cast warewashing composition is produced for use in automatic washing machines at low temperatures. A liquid detergent composition is cast into a mold where it is allowed to solidify. The solid cast detergent, surrounded on all but its upper surface by the mold, is used in automatic washing machines having a dispensing device designed to dispense a liquid aqueous detergent formed from the solid cast detergent using an impinging liquid spray. The liquid aqueous detergent flows out of the dispensing device generally simultaneously with its formation in the dispenser. The cast detergent composition includes about 5 to 12 wt-% of a nonionic surfactant, an alkali metal hydroxide, a sequestrant, water of hydration and optionally further includes one or more preformed cores or plugs comprising an available chlorine source, a defoamer, or the like.

Low temperature cast detergent-containing article and method of making

A solid cleaning concentrate composition for aqueous dilution to form a non-filming floor cleaner, said concentrate comprising a major portion of a carrier for inertly containing the active ingredients of said concentrate in a solid cast mass prior to dilution, said active ingredients comprising an effective amount of a surfactant component for imparting wettability and lypophilic solubilizing character to said non-filming floor cleaner an effective amount of a solubilizer for solvating fatty oils and grease on the surface of application, and an effective amount of alkali for maintaining said non-filming floor cleaner above a pH of 9.0 upon dilution.
