Definitions
- the present invention relates to a low temperature solid cast three-dimensional, detergent composition
- a low temperature solid cast three-dimensional, detergent composition comprising an alkali metal hydroxide, 5 to 12.6 wt-% of a nonionic surfactant, a hardness sequestering agent, and water of hydration.
- the invention can further comprise a receptacle-shaped mold surrounding and containing the detergent composition on all but one surface.
- the detergent composition is normally formed by mixing and heating the components in an aqueous solution, thickening the solution, pouring the solution into the mold and preferably also cooling it, and allowing the mixture to solidify, it being understood that the solidification can involve one or more physico-chemical mechanisms, including "freezing", precipitation from solution, hydration, etc.
- Preformed plugs or cores of a chlorine source and/or a defoamer can be inserted in the mixture after it has been added to a mold and before it has solidified.
- the cast detergent composition is preferably left in the disposable mold in which it was cast.
- the cast detergent can be demolded and inserted in an inexpensive container or receptacle which has substantially the same configuration as the mold, since in either case the cast detergent is surrounded on all but one surface, as described previously.
- the thus-surrounded cast detergent is used by placing its exposed surface in a drainable position (preferably fixed) within a detergent dispensing apparatus.
- a third necessary component of the low temperature solid cast detergent composition of this invention is a nonionic surfactant. It has been bound that at low water temperatures, the cleaning power of alkali metal hydroxide can be reduced depending upon soil load and type. To obtain desired low temperature cleaning results, a nonionic surfactant is added to augment the cleaning action of the alkali metal hydroxide. The nonionic surfactant serves to emulsify fats rather than saponify them. The nonionic surfactant used must be compatible with the alkali metal hydroxide and must be low foaming. Useful nonionic surfactants include, but are not limited to, the following: an ethoxylated long chain alcohol which is terminated with a benzyl group.
- the sequestrant is utilized in its anhydrous form for reasons of cost.
- a sequestrant in its hydrated form could be utilized if the water content of the other raw materials is adjusted downward to compensate for the water of hydration contained in the sequestrant.
