Title: Multi-purpose cleaning compositions and method

Description:
FIELD OF THE INVENTION 
     In general, various embodiments of the present invention relates to the field of cleaning compositions for cleaning substrates and/or surfaces, and to a method of cleaning one or more substrates and/or surfaces. In one embodiment, the present invention relates to various multi-purpose cleaning compositions that are formed from a combination of at least one inorganic pyrophosphate (e.g., at least one Group 1 pyrophosphate) and at least one surfactant. In one or more instance, the various embodiments of the present invention relate to multi-purpose cleaning compositions that are suitable for use on various substrates including, but not limited to, hard surfaces, textiles, carpet and skin, and to methods of cleaning such substrates and/or surfaces. 
     BACKGROUND 
     A variety of cleaning formulations are available for household use on hard surfaces such as countertops, for use on textiles on upholstery and carpets, for example. Still other cleaning formulations are used on skin to remove dirt and greases, etc. 
     Several considerations in formulating such compositions include the cleaning ability to dissolve stains and dirt as well as the ability to remove them. For example, in surface cleaning formulations for carpeting, some conventional cleaning compositions interact with the dirt or stain, and the residue can be later removed with a vacuum. 
     Despite their convenience, several conventional cleaning formulations suffer from a number of disadvantages. Compositions used on hard surfaces such as countertops and porcelain and plastic plumbing fixtures, for example, are acidic or caustic and can damage the substrate to which they are applied. They can also present safety or health hazards to the user. Some carpet compositions, for example, have not have been effective in removing particular stains and even heavy traffic soil stains, while they may also leave behind a tacky residue. The presence of high amount of residues in particular sticky residues contributes to carpet re-soiling which makes the carpet lose its color and brightness. Still yet other stain removers will cause carpet or fabric to change or lose its color. 
     There remains a need for alternative cleaning compositions useful in removing difficult stains, soap scum, and/or odor from hard and soft surfaces such as carpets, rugs and textiles, without imparting undesirable properties described above or the harmful and toxic exposure to those who use or come into contact with the products. 
     SUMMARY 
     In general, the present invention relates to the field of cleaning compositions for cleaning substrates, and the method of cleaning the substrates. In one embodiment, the present invention relates to various multi-purpose cleaning compositions that are formed from a combination of at least one inorganic pyrophosphate (e.g., at least one Group 1 pyrophosphate) and at least one surfactant (e.g., at least one anionic, cationic, amphoteric and/or non-ionic surfactant). In another embodiment, the present invention relates to various multi-purpose cleaning compositions that are formed from a combination of at least one Group 1 pyrophosphate (e.g., sodium pyrophosphate, potassium pyrophosphate, or a mixture thereof), at least one surfactant (e.g., at least one anionic, cationic, amphoteric and/or non-ionic surfactant), and at least one solvent (e.g., water, alcohol, or a mixture thereof). In still another embodiment, the various cleaning compositions of the present invention can further include a wide variety of optional ingredients including, but not limited to, anti-bacterial compounds, anti-mildew compounds, deodorizers, fragrances, perfumes, anti-static, anti-fungal, UV protectantes, etc. In one or more instance, the various embodiments of the present invention relate to multi-purpose cleaning compositions that are suitable for use on various substrates including, but not limited to, hard surfaces, textiles, carpet and skin, and to methods of cleaning such substrates and/or sufarces.

     DETAILED DESCRIPTION 
     In general, the present invention relates to the field of cleaning compositions for cleaning substrates, and the method of cleaning the substrates. In one embodiment, the present invention relates to various multi-purpose cleaning compositions that are formed from a combination of at least one inorganic pyrophosphate (e.g., at least one Group 1 pyrophosphate) and at least one surfactant (e.g., at least one anionic, cationic, amphoteric and/or non-ionic surfactant). In another embodiment, the present invention relates to various multi-purpose cleaning compositions that are formed from a combination of at least one Group 1 pyrophosphate (e.g., sodium pyrophosphate, potassium pyrophosphate, or a mixture thereof), at least one surfactant (e.g., at least one anionic, cationic, amphoteric and/or non-ionic surfactant), and at least one solvent (e.g., water, alcohol, or a mixture thereof). In still another embodiment, the various cleaning compositions of the present invention can further include a wide variety of optional ingredients including, but not limited to, anti-bacterial compounds, anti-mildew compounds, deodorizers, fragrances, etc. In still another embodiment, the present invention relates to various cleaning compositions that are suitable for use on various substrates including, but not limited to, hard surface substrates, textiles, carpet and skin, and to methods of cleaning such substrates. 
     In one embodiments, the various compositions of the present invention are in liquid form, solid form, or in the form of a liquid suspension. In the embodiments, where at least one glycol ether is present, the compounds of the present invention can either be in liquid form or in the form of a liquid suspension. In the case of solid, or powdered, forms of the present invention, such compositions can be diluted in one or more suitable solvents in order to form suitable cleaning compositions designed to treat one or more substrates. In another embodiment, such solid, or powdered, compositions in accordance with one or more embodiments of the present invention can be used to form liquid cleaning concentrates. Such concentrates are formed when a suitable composition in accordance with one or more embodiments of the present invention is added to an amount of solvent less than the amount of solvent necessary to form a cleaning composition of a desired application concentration or strength. Such concentrates can be further diluted to a desired application concentration at, or near, the time of use.

     EXAMPLES 
     Comparative evaluations for conducted to demonstrate the unexpected cleaning performance of the inventive compositions. Carpet samples made of 100% nylon manufactured by Mohawk having style Rock Creek no. 62892, having an herbal/tan color was used in the testing. Six types of stain materials are listed below in Table I and were applied onto the carpet samples. The spaghetti sauce was worked in the nap by hand, and the lipstick and crayon were rubbed on the carpet. The Kool-aid®, asphalt and paint were sprayed on the carpet. The stain materials were applied and allowed to dry for three days. 
     Comparative cleaning compositions (Control 1 and Control 2), and a multi-purpose cleaning composition of the present invention (Example 1) were tested using the following protocol. Some stained materials were sprayed on to the carpet and others were brushed on with a hand brush. The lipstick, spaghetti sauce, crayon, asphalt and paint stain materials were sprayed with six pumps with each of the cleaning composition. As much as the stain as possible was extracted with a 100% cotton terry cloth. A new cloth was used for each stain and for each cleaner. The Kool-aid® stain material was first brushed with a hand brush. The stains were sprayed with 20 pumps of the cleaner. As much of the stain as possible was extracted with a 100% cotton terry cloth, and a new cloth was used for each stain and each cleaner. The cloth was then rinsed in water and another 6 pumps of each cleaner was applied to the respective carpet spots. The stain was extracted repeatedly with the cloth for a total of 6 extractions on each stain. 
     Clean carpet panels which were stained with Kool-aid were tested for a removal process using heat. The carpet panels were stained and then allowed to dry for four days. A fresh cloth was soaked in water and was placed over the stains. Heat was applied using an iron (1200 Watts and set to maximum heat) which was placed on the wet rag for about 15 seconds. The panels were judged for stain removals and the rankings are listed in the Table I below, with a rating of 1 being the best stain removal to a rating of 3 being the worst.

     Tests were performed on chrome, porcelain, painted walls, glass, acrylic. 1 oz of solution (calcium+magnesium salts dissolved in DI water). Also in solution was 1 gram ivory bar soap/1 oz H2O, was sprayed on each substrate and allowed to dry for 24 hours. 7×7 identical squares (2″×2″) were used as test panels. 5 mL each sample of multi-purpose cleaning composition were then applied to center of substrate, and allowed 15 minutes to work on dried soap scum. Substrates were then rinsed with DI water and dried (air). Table II shows that the multi-purpose cleaning composition of Example 3 containing by weight, 4% sodium lauryl sulfate, 4% tetrapotassium pyrophosphate, and 92% water, was the only one with no fumes and no damage to any substrate. Example 4 was only one that removed all of soap scum on all substrates. A rating of 1 was the best and 7 was the worst.

     Tests were performed on 2″×2″ square unfinished leather. Samples were soiled with grease (automotive), used motor oil, pine tar, mud, transmission fluid. Samples were allowed to dry for 24 hours. The multi-purpose cleaning composition herein and four competitor&#39;s products were tested. 5 mL each product applied to center of squares with cotton swab in circular motion. After five minutes samples were wiped with water dampened cotton towel. Table III below shows the results and only Example 4 which contained sodium lauryl sulfate, tetra potassium pyrophosphate, glycerol, water removed all soils and left leather supple and no residue. A rating of 1 was the best and a rating of 4 was the worst.
