A method of warewashing for the removal of starch is described herein. The method includes applying an alkaline composition to a dish, then applying an acidic composition to a dish, and then applying a second alkaline composition to the dish. The method may include additional steps. Compositions for using with the method are also disclosed. Finally, dish machines that may be used in accordance with the method are disclosed.

Methods and compositions for the removal of starch

Starch is removed from the surface of an article using a multi-step method that includes presoaking the article in an acidic solution to remove the starch from the surface of the article and washing the article in an alkaline solution to clean the article.

Starch removal process

An alkaline detergent composition is provided including a source of alkalinity and an effective soil removing amount of a nonionic surfactant blend. The nonionic surfactant blend includes a nonionic surfactant having a hydrophobic and an (EO) group and a nonionic silicone surfactant. The detergent composition provides for the removal of waxy-fatty soil.

Combination of a nonionic silicone surfactant and a nonionic surfactant in a solid block detergent

An alkaline detergent composition is provided including a source of alkalinity and an effective soil removing amount of a nonionic surfactant blend. The nonionic surfactant blend includes a monionic surfactant having a hydrophobic and an (EO) group and a nonionic silicone surfactant. The detergent composition provides for the removal of waxy-fatty soil.

A process for preparing a homogeneous, solid cleaning composition that comprises a cleaning agent, and optionally an additive agent and a hardening agent is provided. The compositions are processed in a continuous mixing system at high shear, at or below the melting temperature of the ingredients. Preferably, the ingredients are processed in an extruder, and the mixture is extruded directly into a mold or other packaging system for dispensing the cleaning composition. The consistency of the composition ranges from that of a fused block solid to a malleable article. The cleaning compositions are useful for warewashing and cleaning hard surfaces, rinsing, sanitizing, deodorizing, laundry detergents, conveyor lubricants, and the like.

Method of making non-caustic solid cleaning compositions

The invention relates to a A highly alkaline or mildly alkaline detergent composition having enhanced cleaning properties. The detergent which combines a source of alkalinity and with a blend of nonionic surfactants that enhances cleaning waxy-fatty soils. This blend of surfactants shows surprising cooperation in reducing surface tension and comprises a nonionic or amphoteric surfactant and a silicone containing surfactant.

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

Improved separation of emulsified hydrophobic organic soils can be obtained from aqueous effluents using an amphoteric carboxylate surfactant material in combination with cationic destabilizer or flocculent materials. Such a treatment in combination with an acidic pH adjustment causes the rapid separation of hydrophobic organic soils from the aqueous stream. The treated aqueous stream is environmentally compatible. Improved laundry detergents comprising an organic amphoteric carboxylate surfactant and selected nonionic surfactants provide both cleaning for fiber and fabric containing items soiled with substantial quantities of hydrophobic soil. The pH of an effluent generated in such cleaning processes can be adjusted to an acid pH and treated with a cationic material causing a break that permits rapid and substantially complete separation of the hydrophobic organic soils from the effluent. Residual concentrations of organic soil in effluent water can be less than 250 ppm and can be as low as 10 ppm.
