Abstract

A solid cast warewashing composition is produced for use in automatic washing machines at low temperatures. The solid cast detergent 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. The cast detergent composition includes at least about 4 wt.-% of a nonionic surfactant, an alkali metal hydroxide, a sequestrant, and water of hydration.

Description

Claims

WHAT IS CLAIMED IS:
1. A solid cast warewashing detergent composition which comprises:
(a) about 2 to 10 wt-% of a nonionic surfactant;
(b) about 10 to 60 wt-% of an alkali metal hydroxide;
(c) about 10 to 50 wt-% of a hardness-sequestering agent; and (d) about 5 to 30 wt-% water of hydration; wherein each percentage is based upon the cast composition.
2. The cast composition of Claim 1 which further comprises a receptacle-shaped disposable container surrounding said detergent composition on all but one surface thereof.
3. A cast composition according to Claim 1, wherein said container is the mold in which said composition was cast and solidified.
4. A cast composition according to Claim 3, which further comprises a cover attached to the said receptacle-shaped container.
5. A cast composition according to Claim 1, wherein said composition additionally comprises a defoamer.
6. A solid cast warewashing detergent composition which comprises:
(a) about 4 to 8 wt-% of a nonionic surfactant;
(b) about 20 to 50 wt-% of an alkali metal hydroxide.
(c) about 15 to 34 wt-% of a hardness- sequestering amount of an alkali metal condensed phosphate;
(d) about 10 to 20 wt-% of water of hydration; (e) about 2 to 7 wt-% of a polyelectrolyte; and
(f) up to about 1.0 wt-% of a defoamer.
7. A method for dispensing warewashing detergent into a warewashing zone for washing ware, using the solid cast warewashing detergent composition of Claim 1, comprising the following steps:
(a) placing said solid cast warewashing detergent composition in a detergent dispensing device having a spray means, in a position with respect to the horizontal and with respect to said spray means, for dispensing detergent downwardly from said detergent composition to the warewashing zone of a warewashing machine, whereby the side of the solid cast warewashing detergent composition not surrounded by said receptacle-shaped container is contained within the interior of said detergent dispensing device and is oriented to provide the interior of said detergent dispensing device with essentially one unsurrounded, exposed, drainable surface of solid cast warewashing detergent composition;
(b) impinging a spray of aqueous liquid from said spray means upon said unsurrounded, exposed, drainable surface to dissolve detergent composition at a generally consistent rate and thereby form an aqueous liquid detergent containing said detergent composition in the aqueous liquid, which aqueous liquid detergent drains downwardly from said unsurrounded, exposed, drainable surface generally simultaneously with said impinging;
(c) generally simultaneously permitting the downwardly-draining aqueous liquid detergent to flow out of said detergent dispensing device and into said warewashing zone for the purpose of washing ware wherein; and
(d) controlling the duration of said step (b), thereby controlling the amount of said aqueous liquid detergent composition flowing into said warewashing zone, thereby controlling the concentration of said detergent composition in said warewashing zone.
8. A method according to Claim 7, wherein said unsurrounded, exposed, drainable surface generally faces toward said spray means.
9. A method according to Claim 8, wherein said solid cast warewashing detergent composition is placed in accordance with said step (a) in an inverted position above said spray means, such that said unsurrounded, exposed, drainable surface faces downwardly toward said spray means.
10. A method according to Claim 7, wherein in said step (a), said solid cast warewashing detergent composition is placed in an inverted position over said spray means, and said impinging is provided by a spray oriented generally perpendicularly to said unsurrounded, exposed, drainable surface.
11. A process for forming a solid cast warewashing detergent composition which comprises:
(a) heating about 60-70 parts by weight of a 40 -75 wt-% aqueous solution of an alkali metal hydroxide to about 150 to 160° F. (65.6-71.1°C.);
(b) distributing about 2 to 10 wt-% of a nonionic surfactant in said solution;
(c) distributing about 10-50 wt-% of a hardness-sequestering agent in said solution;
(d) thickening said solution, and mixing said solution during said thickening to form a castable uniform dispersion;
(e) pouring said uniform dispersion into said receptacle-shaped mold and at least partly filling said mold; and
(f) allowing said thickened dispersion to solidify in said mold to a uniform, solid cast detergent wherein at least one surface of the cast detergent is exposed by the receptacle-shaped mold.
12. The process of Claim 11, wherein said alkali metal hydroxide is sodium hydroxide.
13. The process of Claim 12, wherein said hardness-sequestering agent is sodium tripolyphosphate.
