In some embodiments, the antimicrobial composition can comprise about 12 wt% of sodium percarbonate and about 6 wt% of tetraacetylethylenediamine, both amounts based on the total weight of the cleaning composition.

[0025] It has unexpectedly been found that an antimicrobial composition comprising a combination of sodium percarbonate and tetraacetylethylenediamine provides an unexpected improvement in reducing bacteria in a solid cleaning composition. As discussed in more detail herein, it has been found that the combination of sodium percarbonate and tetraacetylethylenediamine provides an unexpected reduction in at least bacteria (including Escherichia coli, Salmonella typhimurium, Staphylococcus aureus, Pseudomonas aeruginosa) within a relatively short contact time (i.e., less than about 10 minutes) after the cleaning composition is in a dissolved state.

[0026] The cleaning composition can be effervescent. The cleaning composition can comprise an effervescent component. The effervescent component can cause the cleaning composition to foam upon contact with water. Effervescence can be the result of gas trapped in the particle matrix being released when the particles contact water, or more commonly the result of a reaction between two or more reactants present in the effervescent particles that react with each other upon contact with water to produce gas.

[0027] The time taken for an effervescent product to dissolve is affected by several factors. Key among these factors, in addition to the environment in which it is used, are: its form (tablet, granule or powder); its size and its density; its hardness and the formulation itself. Effervescent compositions (such as the cleaning compositions of the present invention) can dissolve rapidly, typically within seconds. Such effervescent compositions typically react immediately on the surface of water.

[0028] Based on the total weight of the cleaning composition, the effervescent component can be present in an amount ranging from about 22 wt% to about 40 wt% (including all percentages and sub-ranges therebetween). In some embodiments, based on the total weight of the cleaning composition, the effervescent component can be present in an amount ranging from about 25 wt% to about 37 wt% (including all percentages and sub-ranges therebetween).

[0029] The effervescent component can comprise a blend of an acid source and a carbonate. The carbonate and the acid source can be present in a weight ratio ranging from about 1.5:1 to about 5.5:1 (including all ratios and sub-ranges therebetween). In some embodiments, the carbonate and the acid source can be present in a weight ratio ranging from about 1.5:1 to about 4.8:1 (including all ratios and sub-ranges therebetween).

[0030] A curing agent (also known as a binder) can be used to physically "glue" the acid source and the carbonate together, as discussed in more detail herein.

[0031] Non-limiting examples of carbonates include sodium bicarbonate, sodium carbonate, potassium carbonate, potassium bicarbonate, magnesium carbonate, and calcium carbonate. In some embodiments, the carbonate of the effervescent component is an alkali metal bicarbonate. In some embodiments, the alkali metal bicarbonate is sodium bicarbonate.

[0032] Non-limiting examples of acid sources include solid organic, mineral, or inorganic acids, salts, or derivatives thereof or mixtures thereof. In some embodiments, the acid source can be a monoprotic acid, a diprotic acid, or a triprotic acid. Such acids can include monocarboxylic acids or polycarboxylic acids, such as citric acid, adipic acid, glutaric acid, tartaric acid, maleic acid, fumaric acid, malic acid, succinic acid, salicylic acid, and malonic acid. Such acids can be in their acidic form. Alternatively, the acid source can include esters of the acid. In some embodiments, the acid source is one or more of citric acid and malic acid. In some embodiments, the acid source is citric acid. The acid source, such as any of the foregoing acids, can be incorporated as its salt.

[0033] Based on the total weight of the cleaning composition, the acid source of the effervescent component can be present in an amount ranging from about 5 wt% to about 15 wt% (including all percentages and sub-ranges therebetween). For example, based on the total weight of the cleaning composition, the acid source can be present in the cleaning composition in the following amounts: about 5 wt% to about 15 wt%, about 5 wt% to about 12 wt%, about 5 wt% to about 9 wt%, about 5 wt% to about 7 wt%; about 7 wt% to about 15 wt%, about 7 wt% to about 12 wt%, about 7 wt% to about 9 wt%; about 9 wt% to about 15 wt%, about 9 wt% to about 12 wt%; about 11 wt% to about 15 wt%, about 11 wt% to about 13 wt%, about 12 wt% to about 15 wt%, including all percentages and sub-ranges therebetween. In some embodiments, based on the total weight of the cleaning composition, the acid source of the effervescent component can be present in an amount ranging from about 6 wt% to about 12 wt% (including all percentages and sub-ranges therebetween).

[0034] Based on the total weight of the cleaning composition, the carbonate and / or bicarbonate of the effervescent component can be present in an amount ranging from about 15 wt% to about 35 wt% (including all percentages and sub-ranges therebetween). For example, based on the total weight of the cleaning composition, the carbonate and / or bicarbonate can be present in the following amounts: about 15 wt% to about 35 wt%, about 20 wt% to about 35 wt%, about 25 wt% to about 35 wt%, about 30 wt% to about 35 wt%; about 15 wt% to about 30 wt%, about 20 wt% to about 30 wt%, about 25 wt% to about 30 wt%; about 15 wt% to about 25 wt%, about 20 wt% to about 25 wt%; about 15 wt% to about 23 wt%, about 15 wt% to about 20 wt%, including all percentages and sub-ranges therebetween.

In some embodiments, based on the total weight of the cleaning composition, the carbonate of the effervescent component can be present in an amount ranging from about 25 wt% to about 31 wt% (including all percentages and sub-ranges therebetween).

[0035] The cleaning composition can comprise a separate and / or additional alkaline source. The separate and / or additional alkaline source can be incorporated into the cleaning composition to enhance the cleaning of the substrate and / or improve the impurity removal performance of the cleaning composition. If desired, a separate alkaline source can be incorporated into the cleaning composition to impart an alkaline pH, as discussed.

[0036] The separate and / or additional alkaline source can include one or more of alkali metal carbonates and / or alkali metal hydroxides. Non-limiting examples of alkali metal carbonates include carbonates, bicarbonates, sesquicarbonates, and mixtures thereof of sodium or potassium. Non-limiting examples of alkali metal hydroxides can include sodium hydroxide or potassium hydroxide.

[0037] In some embodiments, the separate and / or additional alkaline source includes sodium carbonate. In some embodiments, the separate and / or additional alkaline source includes sodium carbonate as light soda ash.
