Methods employing detergent compositions effective for reducing soil redeposition and accumulation on hard surfaces are disclosed. The detergent compositions employ phosphinosuccinic acid adducts in combination with an alkalinity source and gluconic acid or salts thereof, copolymers of acrylic acid and maleic acids or salts thereof, sodium hypochlorite, sodium dichloroisocyanurate or combinations thereof.

Method of reducing soil redeposition on a hard surface using phosphinosuccinic acid adducts

The present invention is a solid rinse aid composition and methods of making and using the same. The solid rinse aid composition generally includes sodium sulfate and urea as solidification agents and an effective amount of an alcohol ethoxylate compound sheeting agent component and an effective amount of defoamer component. The solid rinse aid composition may also incorporate a preservative system including sodium bisulfate. The solid rinse aid composition may be phosphate-free, aminocarboxylate-free, and GRAS if desired.

Dimensionally stable solid rinse aid

A treated oxidizing agent is provided according to the invention. The treated oxidizing agent includes an oxidizing agent that is solid at room temperature and atmospheric pressure, and a chemical barrier composition provided on the oxidizing agent. The chemical barrier composition includes a hydrocarbon component having about 10 to about 85 carbon atoms, and wherein the chemical barrier composition is provided as a liquid at 25&#xb0; C. A solid detergent composition is provided including the treated oxidizing agent. Methods for manufacturing are provided.

A water-driven jet or venturi extraction means is used to remove, capture and cool the hot, highly humid air created within commercial dishwashers during a wash rinse or sanitization cycle. A cold water spray is used to create a pressure reduction zone which serves to draw in hot, highly humid air from the dishwasher. Water vapor cools and condenses on contact with the cold water spray within the venturi. The invention also serves to help vent the dishwasher. Cool, fresh air is drawn into the dishwasher while the hot air is drawn into the venturi.

We have found that long standing problems relating to the stability of organic materials in alkaline detergents, including the reversion or hydrolysis of condensed phosphate sequestrants in alkaline solid detergent compositions can be alleviated by the use of an organic composition having vicinal hydroxyls. Such a solid block detergent can be manufactured by a process in which a source of alkalinity, a functional material including a condensed phosphate sequestering agent, an organic compound having two vicinal hydroxyl groups, are combined in a pourable composition or liquid. Such a liquid can be introduced into a plastic capsule and solidified. During manufacture and solidification, we have found that the vicinal hydroxyl compound prevents substantial hydrolysis or reversion of the condensed phosphate maintaining effective hardness ion sequestration during the use of the detergent. The stabilizer can also stabilizes color, chlorine content and dispensing properties.

Alkaline solid block composition

The invention provides a urea based solid composition and a process for preparing a homogeneous, urea-based, solid cleaning composition. Cleaning compositions for use in warewashing and cleaning hard surfaces, rinsing, sanitizing, deodorizing, and the like, made by the method are also provided. The ingredients are charged into a heated mixing apparatus and when uniform are transferred into a mold or other packaging system for dispensing the detergent. The consistency of the composition ranges from that of a fused solid block to a malleable article.

Urea-based solid alkaline cleaning composition

An active-halogen bleach such as dichloroisocyanurate encapsulated in a coating of dihydratea synthetic detergent such as sodium octyl sulfonate. The capsule may further comprise an initial coating of a soluble inorganic detergent builder or filler such as an alkali metal phosphate or sulfate. The capsule is stable in highly alkaline environments such as detergent compositions. Solid cast detergent-bleach composition having minimal bleach degradation comprising an alkaline hydratable chemical such as sodium hydroxide, a hardness sequestrant such as sodium tripolyphosphate, water of hydration and encapsulated active-halogen bleach formed in accordance with this invention. Optionally the detergent-bleach composition may contain a polyelectrolyte such as polyacrylate.
