14. A kitchen detergent formulation according to claim 13, wherein the water softener is present in an amount ranging from about 10% by weight to about 40% by weight.
15. A kitchen detergent formulation according to claim 1, further comprising an anionic surfactant.
16. A kitchen detergent formulation according to claim 15, wherein the anionic surfactant is sodium coco sulfate, sodium methyl oleoyl taurate, sodium lauryl sulfate, or a combination thereof.
17. A kitchen detergent formulation according to claim 15, wherein the anionic surfactant is present in an amount ranging from about 1% by weight to about 20% by weight.
18. A kitchen detergent formulation according to claim 1, further comprising a liquid component carrier or a flow aid.
19. A kitchen detergent formulation according to claim 18, wherein the amount of the liquid component carrier or flow aid is in the range of 0.1 to 1 weight%.
20. A kitchen detergent formulation according to claim 18, wherein the liquid component carrier or flow aid is hydrated silica.

Description

Stable Anhydrous Dishwashing Soap and Method of Making Same The majority of dish soap products for hand washing or dishwashers are supplied as liquids in dispenser containers or in packs/pods packaged in polyvinyl alcohol/plastic. They can also be supplied in bulk as liquids or as refills for packs/pods. These containers are mostly made of plastic, glass, polyvinyl alcohol, or cardboard lined with plastic as a water barrier. For example, hand-wash dish soaps on the market generally contain less than 40% by weight of solids relative to the weight of the dish soap. One of the problems is packaging. Disposable plastics are ubiquitous and are destroying the environment. Only 9% of all plastic is actually recycled, and packaging generates the largest portion (~30%) of municipal waste. Packaged products are inefficient for businesses and consumers. Removing water from hand kitchen detergent formulations eliminates the need for single-use plastic packaging and the resulting waste, such as packaging waste, product waste, and resource equipment used to transport water. Therefore, there is a need for new stable formulations of hand-wash kitchen detergents and dishwashers in solid form that meet consumer demands while also reducing the amount of waste generated during production and shipment. Summary of the Invention The present invention relates to a stable, anhydrous, solid form kitchen detergent formulation (“kitchen detergent formulation”). The solid form includes tablets, free-flowing powders, crystals/beads, granules, flakes, confetti, extruded, spray-dried, and spray-coated foam. In some embodiments, the kitchen detergent formulation is suitable for hand-washed dishes and may be placed in a non-rigid wrapper or non-container. In some embodiments, the kitchen detergent formulation is suitable for dishwashers. In one aspect of the present invention, a dishwashing detergent formulation is provided. The dishwashing detergent formulation comprises a surfactant and a filler, and more than 40 weight% of the dishwashing detergent formulation is solid and the dishwashing detergent formulation substantially does not contain fatty acids. In another aspect, a method for manufacturing a kitchen detergent formulation is provided. In another aspect, a method of using a kitchen detergent formulation is provided. The present disclosure relates to a stable, anhydrous dishwashing detergent formulation in solid form (“dishwashing detergent formulation”). The dishwashing detergent formulation contains more than 40 weight percent of solids and is environmentally friendly and effective for cleaning dishes. Advantages of the dishwashing detergent formulation over traditional liquid dishwashing detergents include chemical stability, reduced packaging, and convenience for consumers. The dishwashing detergent formulation described herein can outperform leading liquid dishwashing detergents for burnt cheese and heavily burnt paste sauces. As used in this specification, singular expressions include plural references unless the context clearly indicates otherwise. Thus, for example, a reference to "surfactant" includes a single type of surfactant or two or more different types of surfactants. The term "anhydrous" as used herein refers to a dishwashing detergent formulation containing less than about 5% by weight of water based on the weight of the dishwashing detergent. As used herein, the term “substantially fatty acid-free” refers to a stable, anhydrous dishwashing detergent formulation containing 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or less than 1% by weight of fatty acids (including animal fats (e.g., tallow) and vegetable oils (e.g., coconut oil and palm oil)) or salts thereof. The terms “anionic surfactant-free,” “alginate-free,” “alcohol-free,” “glycol-free,” “glycerol-free,” “sodium sulfate-free,” and “polyvinyl alcohol-free” as used herein relate to kitchen detergent formulations comprising, respectively, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or less than 1% by weight of anionic surfactant, alginate, alcohol, glycol, glycerol, sodium sulfate, and polyvinyl alcohol based on the weight of the kitchen detergent formulation. The term "comprising" includes embodiments of "consisting of" or "essentially consisting of". In one embodiment, a stable anhydrous dishwashing detergent formulation in solid form is provided. The dishwashing detergent formulation comprises a surfactant and a filler, wherein the dishwashing detergent formulation comprises more than 40 weight percent of solid and substantially does not contain fatty acids. The filler may be present in an amount that fills 100% of the percentage of the dishwashing detergent. In some embodiments, the amount of filler in the dishwashing detergent may be in the range of 35 to 50 weight percent based on the weight of the dishwashing detergent. In some embodiments, the solid form is a free-flowing powder, crystals/beads, granules, flakes, confetti, extruded, spray-dried, or spray-coated f
