Description

CLEANING COMPOSITIONS AND METHODS OF USE THEREOF

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority benefit of U.S. Provisional Patent Application No. 61/889,520 filed October 10, 2013, which is hereby incorporated herein by reference in its entirety.

BACKGROUND

There are a number of cleaning products on the market that advertise the product can readily remove a number of different stains from fabrics and textiles. Particularly common but difficult stains include mustard, grape juice, wine, coffee, ketchup, soda, and the like. While some of these commercially-available products may be useful in removing some of these stains, there is no one single product that is effective in removing a multitude of stains. Thus, it would be desirable to have a cleaning composition that can readily remove multiple stains from a variety of substrates. Moreover, it would be desirable if the cleaning composition could be formulated in a number of different forms so that it could be used in a variety of applications.

SUMMARY

Described herein are cleaning compositions useful in the removal of multiple stains and biological growth from a variety of different substrates. The cleaning compositions include several components that when combined permit the removal of difficult stains and biological growth. The cleaning compositions can be formulated in liquid and solid form, which permits them to be used in a number of applications where it is desirable to remove stains and biological growth.

The advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the aspects described below. The advantages described below will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive. DETAILED DESCRIPTION

Before the present compounds, compositions, and/or methods are disclosed and described, it is to be understood that the aspects described below are not limited to specific compounds, synthetic methods, or uses as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.

In this specification and in the claims that follow, reference will be made to a number of terms that shall be defined to have the following meanings:

It must be noted that, as used in the specification and the appended claims, the singular forms "a," "an" and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a stain" includes one or more such stains.

As used herein, the term "comprising" means various components conjointly employed in the preparation of the composition or methods of the present disclosure. Accordingly, the terms "consisting essentially of and "consisting of are embodied in the term "comprising".

"Optional" or "optionally" means that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where the event or circumstance occurs and instances where it does not. For example, the phrase "optionally includes a surfactant" means that the surfactant can or cannot be included in the cleaning composition and that the description includes cleaning compositions where the surfactant is included and compositions where it is not included.

References in the specification and concluding claims to parts by weight, of a particular element or component in a composition or article, denotes the weight relationship between the element or component and any other elements or components in the composition or article for which a part by weight is expressed. Thus, in a compound containing 2 parts by weight of component X and 5 parts by weight component Y, X and Y are present at a weight ratio of 2:5, and are present in such ratio regardless of whether additional components are contained in the compound. A weight percent of a component, unless specifically stated to the contrary, is based on the total weight of the formulation or composition in which the component is included.

By "contacting" is meant an instance of exposure by close physical contact of at least one substance to another substance. For example, contacting can include contacting a substrate surface having a stain with a cleaning composition described herein.

"Removal" or "removing" with respect to a stain or biological growth means either the complete removal of the stain or biological growth or substantial removal of the stain or biological growth so that the stain or biological growth is not visible to the naked eye. For example, the cleaning compositions described herein can remove greater than 90%, greater than 95%, greater than 99%, or 100% of the stain or biological growth from the substrate.

The term "substrate" is any surface possessing a stain or biological growth where it is desirable to remove a stain or biological growth.

In one aspect, the substrate is a textile. The term "textile" refers to any flexible material composed of a network of natural or artificial fibers, including natural, artificial, and synthetic fibers, such as, but not limited to, cotton, linen, wool, polyester, nylon, silk, acrylic, and the like, including blends of various fabrics or fibers. Examples of textiles include, but are not limited to, clothing, carpet, upholstery, and the like.

In another aspect, the substrate possesses a hard surface (e.g., a rigid substrate). Examples of hard surfaces include, but not limited to, buildings (walls, floors), building materials (e.g, tile, stucco, laminate flooring, bath tubs, grout, metal or plastic siding, countertops), dental devices (e.g., dentures), and cookware (dishes, glasses).

The term "stain" is any undesirable discoloration of a substrate where it is desirable to remove the discoloration. The source of the discoloration can include, but is not limited to, mustard, coffee, soda (e.g., coke), juice (e.g., grape), red wine, BBQ sauce, blood, chocolate, and ketchup.

The term "biological growth" is any biological organism that produces an undesirable appearance and/or odor. Examples of biological growth include, but are not limited to, mold and mildew. Described herein are cleaning compositions useful in the removal of multiple stains and or biological growth from a variety of different substrates. In one aspect, the cleaning composition includes

a. a silicate;

b. a glycerol source;

c. a polyvinylpyrrolidone; and

d. a peroxide.

Each component used to prepare the cleaning compositions described herein is discussed in detail below.

Silicates are anionic silicon compounds of the general formula X₂(Si0₂)_nO, where X is cationic species. Not wishing to be bound by theory, the silicate can help neutralize the stain or biological growth on the substrate and brighten the substrate that is contacted by the cleaning composition. In one aspect, the silicate is sodium or calcium silicate. In another aspect, the silicate is a metasilicate such as, for example, sodium metasilicate. For example, METSO BEADS^® 2048 sodium metasilicate manufactured by PQ Corporation can be used herein. In one aspect, the silicate is anhydrous sodium metasilicate in the amount of 5% to 60% by weight of the cleaning composition. In another aspect, the silicate is anhydrous sodium metasilicate in the amount of 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55% or 60% by weight of the cleaning composition, where any value can form the lower and upper end-point of a range.

The glycerol source can be any composition that includes glycerol. The amount of glycerol in the glycerol source can vary; however, in one embodiment, pure (i.e., neat) glycerol can be used as the glycerol source. In another embodiment, the glycerol source can be a compound that can produce or release glycerol. For example, compositions containing triglycerides (e.g., vegetable oils) can be used as the glycerol source. Not wishing to be bound by theory, the glycerol source can help neutralize the stain or biological growth on the substrate as well as bind chemicals present in the stain/biological growth and cleaning composition in order to enhance removal of the stain/biological growth that is contacted by the cleaning composition. In one aspect, the glycerol source is neat, anhydrous glycerol in the amount of 1% to 10% by weight of the cleaning composition. In another aspect, the glycerol source is anhydrous glycerol in the amount of 1%, 2%, 3%, 4%, 25%, 5%, 6%, 7%, 8%, 9%, or 10% by weight of the cleaning composition, where any value can form the lower and upper end- point of a range.

The polyvinylpyrrolidone selected can vary depending upon the application of the cleaning composition. In one aspect, the cleaning composition can include one

polyvinylpyrrolidone. In another aspect, the cleaning composition can include two or more different polyvinylpyrrolidones. Not wishing to be bound by theory, the

polyvinylpyrrolidone helps hold the stain or biological growth in place on the substrate, which helps with the removal of the stain or biological growth from the substrate.

The selection of the polyvinylpyrrolidone can vary depending upon one or more chemical or physical properties of the polymer. In one aspect, the polyvinylpyrrolidone can be selected based on its K- value (e.g., viscosity of a 1% solution of the polyvinylpyrrolidone in centistokes). In one aspect, the polyvinylpyrrolidone has a K value of 5 to 130. In another aspect, the polyvinylpyrrolidone has a K value of 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, or 130, where any value can form the lower and upper end-point of a range. In one aspect, the polyvinylpyrrolidone has a K value of 5 to 15. In another aspect, the

polyvinylpyrrolidone has a K value of 25 to 35. In a further aspect, the cleaning composition includes a first polyvinylpyrrolidone having a K value of 5 to 15 and a second

polyvinylpyrrolidone having a K value of 25 to 35.

In another aspect, the polyvinylpyrrolidone has a molecular weight of 1,000 to 450,000. In one aspect, the polyvinylpyrrolidone has a molecular weight from 1,000 to 10,000. In another aspect, the polyvinylpyrrolidone has a molecular weight of 30,000 to 90,000. In a further aspect, the cleaning composition includes a first polyvinylpyrrolidone having a molecular weight from 1,000 to 10,000 and a second polyvinylpyrrolidone having a molecular weight of 30,000 to 90,000.

In one aspect, the polyvinylpyrrolidone is in the amount of 1% to 20% by weight of the cleaning composition. In another aspect, the polyvinylpyrrolidone is in the amount of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, or 20% by weight of the cleaning composition, where any value can form the lower and upper end-point of a range. The peroxide is any compound containing an oxygen-oxygen single bond. Not wishing to be bound by theory, the peroxide source can help neutralize and reverse stains. In one aspect, the peroxide is a peroxide salt, an organic peroxide, or an inorganic peroxide. In another aspect, the peroxide is an aqueous solution of hydrogen peroxide. The concentration of the hydrogen peroxide can vary depending upon the substrate to be treated. For example, if the substrate is a fabric or article of clothing, lower concentrations of hydrogen peroxide can be used to prevent unwanted bleaching of the fabric. In one aspect, the concentration of the hydrogen peroxide useful herein is of 20%, 25%, 30%, 35%, 40%, 45% or 50% by weight of the hydrogen peroxide aqueous solution, where any value can form the lower and upper end- point of a range. In one aspect, the aqueous solution of hydrogen peroxide (20% to 50%) is in the amount of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, or 20% by weight of the cleaning composition, where any value can form the lower and upper end-point of a range.

Depending upon the application of the cleaning compositions, additional components can be added to the composition in order to enhance the ability of the composition to remove stains and biological growth. In one aspect, the cleaning composition can include one or more alcohols. Not wishing to be bound by theory, the alcohol can help digest biological growth (e.g., mold) and facilitate the drying of the contacted surface. The selection of the alcohol can vary; however, it is desirable that the alcohol be environmentally-friendly and not harmful to the public (e.g., carcinogenic). In one aspect, the alcohol can be a straight-chain substituted or unsubstituted alkyl alcohol (e.g, methanol, ethanol). In another aspect, the alcohol is benzyl alcohol. In one aspect, the alcohol is in the amount of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10% by weight of the cleaning composition, where any value can form the lower and upper end-point of a range.

In other aspects, the cleaning composition can include one or more surfactants. Depending upon the application, the type and amount of surfactant can vary. For example, if the cleaning composition is to be applied to a large surface of the substrate (e.g., the side of a building), the addition of the surfactant can help facilitate the coverage of the substrate by the cleaning composition. The surfactant can include two or more different surfactants depending upon the application. In one aspect, the surfactant is in the amount of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, or 10% by weight of the cleaning composition, where any value can form the lower and upper end-point of a range.

The surfactant can be anionic, nonionic, cationic, or zwitterionic. Examples of anionic surfactants useful herein include the alkyl benzene sulfonic acids and their salts as well as alkoxylated or non-alkoxylated alkyl sulfate materials. Non-limiting examples of anionic surfactants are the alkali metal salts of C10-16 alkyl benzene sulfonic acids, more specifically, Cn_ 14 alkyl benzene sulfonic acids. In some aspects, the alkyl group is linear and such linear alkyl benzene sulfonates are known as "LAS". Alkyl benzene sulfonates, and particularly LAS, are well known in the art. Such surfactants and their preparation are described for example in U.S. Pat. Nos. 2,220,099 and 2,477,383. More particular non-limiting examples of alkylbenzene sulfonates suitable for employment as formulation enabling ingredients include sodium and potassium linear straight chain alkylbenzene sulfonates in which the average number of carbon atoms in the alkyl group is from about 11 to 14. One specific non-limiting example of a formulation enabling ingredient is sodium C11-C14, (e.g., C12) LAS.

Another exemplary type of suitable anionic surfactant is ethoxylated alkyl sulfate surfactants, known as "AES." Such materials, also known as alkyl ether sulfates or alkyl polyethoxylate sulfates, are those which correspond to the formula: R'-0-(C₂H₄0)_n-S0₃M wherein R' is a C8-C20 alkyl group, n is from about 1 to 20, and M is a salt-forming cation. In some aspects, R' is Cio-Cis alkyl, n is from about 1 to 15, and M is sodium, potassium, ammonium, alkylammonium, or alkanolammonium.

Another exemplary type of suitable anionic surfactant is mid-branched primary alkyl sulfate surfactants having an average carbon chain length of from about 14 to about 17 ("MB AS surfactants"). MB AS surfactants with a carbon chain length of about 16 to 17 are known as HSAS surfactants.

Suitable nonionic (NI) surfactants for employment in the compositions described herein may comprise any of the conventional nonionic surfactant types typically employed in liquid detergent products. Such non-ionic surfactants include alkoxylated fatty alcohols and amine oxide surfactants. Non-limiting examples of suitable nonionic surfactants for use herein are alcohol alkoxylate nonionic surfactants.
