NO RINSE, SINGLE STEP CLEANER DISINFECTANT CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to co-pending U.S. Provisional Application No.

62/618,776, filed on January 18, 2018, which is incorporated herein by reference in its entirety.

FIELD OF INVENTION

The present invention relates to a cleaner disinfectant that is composed of ingredients found in food or in products intended to be ingested. The present invention also provides a one-step process for cleaning and disinfecting a surface using the cleaner disinfectant of the invention.

BACKGROUND

Conventionally, the steps needed to return a dirty food contact surface to a clean and hygienic condition are to first clean the surface, then rinse, disinfect the surface and finally rinse the disinfectant from the surface. Conventional surface cleaners that simultaneously clean and disinfect surfaces well enough to meet the requirements set forth under the

European biocidal products directive to be classified as disinfectants are not intended for human consumption and must therefore be rinsed from the surface. Similarly, those cleaners that are not classified as disinfectants are not intended for human consumption and must therefore be rinsed from the surface. In some cases, surfaces must be cleaned and disinfected in separate steps using different products with rinsing being typically required after each step. Rinsing is necessary to ensure that the residual disinfecting solution is entirely removed from the surface to eliminate any risk of transfer to food products that contact the surface after it has been cleaned.

Rinsing is also necessary to remove the ingredients necessary for cleaning from the surface. While certain disinfectants are known that do not need a rinse under the regulations, they do not clean and thus need a separate cleaner that does need to be rinsed. Thus, conventional solutions that clean and disinfect require a rinse. Therefore, a long felt need in the art is for a cleaner/disinfectant combination product that does not require a rinse. This results in a faster cleaning/disinfecting operation.

Additionally, there remains a need in the art for cleaning and disinfectant solutions that effectively clean and disinfect surfaces in a single step process, and do not require being rinsed to insure they are substantially removed from the surfaces of the equipment. The present invention overcomes the issues present in conventional

cleaner/disinfectant solutions by providing formulations that demonstrate good cleaning performance of surfaces as well as a broad spectrum of disinfecting of surfaces without the need to be subjected to rinsing to ensure their entire removal from the cleaned and disinfected surfaces.

The present invention addresses the long-felt need of finding a cleaner disinfectant product that reduces the multiple steps required for cleaning and disinfecting a surface.

SUMMARY OF INVENTION

An aspect of the invention provides a one-step process for cleaning and disinfecting comprising applying a cleaner disinfectant to a surface intended to be contacted with food (the cleaner/disinfectant having a surface active agent), leaving the cleaner disinfectant on the surface without a need for any rinsing, and contacting food on the surface. According to an embodiment of the invention, the cleaner disinfectant includes only one or more of a material that is an ingredient found in food or in products intended to be ingested. Consequently, the food which contacts the surfaces cleaned and disinfected by the present invention do not become contaminated with materials that must be rinsed from the surface— i.e., materials that are not harmful to humans.

In certain embodiments of the invention, the cleaner disinfectant is a diluted cleaner disinfectant having at least a 10 % dilution of a concentrate or a diluted cleaner disinfectant having a 1 % dilution of concentrate in other embodiments of the invention each based upon a weight of the diluted cleaner disinfectant. Even still, in other embodiments of the invention, the cleaner disinfectant is a ready-to-use product that does not require dilution prior to use.

In an embodiment of the invention, the diluted cleaner disinfectant demonstrates antimicrobial efficacy that meets the requirements of both EN1276 at 20°C and EN13697 at 20°C both under dirty conditions. In other embodiments of the invention, the cleaner disinfectant has a cleaning performance comparable to a standard cleaner disinfectant in a standardized cleaning performance test. Such tests are typically conducted with the aid of a Gardner Abrasion Tester (herein after simply referred to as“Gardner”). In certain embodiments of the invention, the soil used in a standardized cleaning performance test comprises protein, starch and lipids. Carbon black is often added to such soil mixtures to aid in visualizing residual soil after cleaning.

DETAILED DESCRIPTION OF THE INVENTION

The present invention now will be described more fully hereinafter, in which some, but not necessarily all embodiments of the inventions are expressly described since, having the benefit of this disclosure, a person having ordinary skill in the art would be able to understand any such embodiments not expressly disclosed. Preferred embodiments of the invention may be described, but this invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The embodiments of the invention are not to be interpreted in any way as limiting the invention. As used in the specification and in the appended claims, the singular forms“a”,“an”, and“the” include plural referents unless the context clearly indicates otherwise. For example, reference to“a cleaner disinfectant” includes a plurality of such cleaner

disinfectants.

Embodiments of the present invention are described herein with reference to various exemplary compounds, including, for example, other compounds that may be functionally the same as those compounds identified as exemplary compounds. As a person having ordinary skill in the art would appreciate, variations from or modifications to the compounds are to be expected in practicing the invention. Such variations and/or modifications can be the result of manufacturing techniques, design considerations, performance and the like, and such variations are intended to be included herein within the scope of the present invention and as further set forth in the claims that follow. The articles of the present invention and their respective components described are not intended to reflect a precise description of the compounds of a formulation and are not intended to limit the scope of the present invention.

Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation. All terms, including technical and scientific terms, as used herein, have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs unless a term has been otherwise defined. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning as commonly understood by a person having ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure. Such commonly used terms will not be interpreted in an idealized or overly formal sense unless the disclosure herein expressly so defines otherwise.

The invention described herein relates to a cleaner disinfectant comprising only one or more of a material that is found in any one or more of a food and a product allowed to be ingested. Another aspect of the invention provides a one-step process for cleaning and disinfecting a surface using the cleaner disinfectant of the invention.

The phrase“allowed to be ingested” as used herein, is not intended to be limiting. A material, a compound and/or a formulation is expressed to be“allowed to be ingested” where such material, compound and/or formulation is a food, a component of food, a product which is allowed by regulation, for example, to be ingested, or a component of a product which is allowed by regulation, for example, to be ingested— for example, a product such as a toothpaste or a nasal spray. In yet other embodiments of the invention, such materials, compounds and/or formulations may be authorized by a governing regulatory agency to be “compatible with food contact surfaces without the need for a rinse”. Again, without intending to be limiting, a material found in a food or a product that may be ingested may be considered“allowed to be ingested”

The phrase“allowed by regulation to be ingested” means a material, a compound and/or a formulation recognized by a competent governing authority such as the European Union and any of its agencies with authority to regulate food, products for use in the human body, or the treatment of food, and food contact surfaces, as being safe for ingestion at the concentrations of interest.”

As used herein,“antimicrobial efficacy” is measured using either one of or both of EN 1276:2009 at 20°C and EN 13697:2015 at 20°C both under dirty conditions.

In certain embodiments of the invention, a cleaning performance test may be used to determine the ability of a solution to remove soil from a surface. A Gardner test or a test using a Gardner test apparatus to determine the extent of cleaning of the cleaner disinfectant of the invention provides may be used. The results using the Gardner test apparatus will vary depending upon the type of soil to be used in the test. The selection of which soil to use may be guided by the desired application performance that a particular disinfectant cleaner is desired to have. Generally, a soil used in a Gardner test should be a composition of the most likely soil components to be encountered in normal use of the product. For a food contact surface cleaner disinfectant such as the cleaner disinfectant of the present invention, the soil should be a blend of protein, starch and lipids. Carbon black is often added to the soil mixture to aid in visualizing residual soil after cleaning.

As used herein,“wt%” refers to the percentage of a named compound based upon the weight of the compound relative to total weight of the solution the compound is embodied within unless expressly provided otherwise.

A cleaner disinfectant of the invention includes only one material or a combination of materials that is found in any one or more of a food and a product allowed to be ingested.

The compound or compounds used in the cleaner disinfectant include compounds that are allowed to be ingested and provide any one or more of cleaning, disinfecting and sanitizing effects.

In certain embodiments of the invention, actual food products may be included in the cleaner disinfectant. Further pursuant to this embodiment of the invention, the cleaner disinfectant comprises, in an exemplary embodiment, any one or more of a vinegar; citrus juice, such as a lemon juice, a lime juice, and/or a grapefruit juice; and certain herbs.

In non-limiting examples, an embodiment of the invention, the cleaner disinfectant may include elderberry, Echinacea, turmeric, calendula, astragalus root, garlic, licorice root, ginger, bark and root of cat’s claw, oregano, and olive leaf. Indeed, the cleaner disinfectant may comprise any herb known to kill bacteria and viruses. In preferred embodiments of the invention, compounds are used in the cleaner disinfectant that do not impart a readily recognizable flavor or fragrance to food processed on the surface after cleaning and disinfecting using the solution. In other preferred embodiments of the invention, compounds are used in the cleaner disinfectant that do not substantially impart a readily recognizable flavor or fragrance to food processed on the surface after cleaning and disinfecting using the solution.

It is known that many food types have compounds that function as bioactive constituents. Such compounds may be good at cleaning, disinfecting, and/or sanitizing.

While the food types may themselves be included directly in such solutions, they may include other ingredients that negatively interact with an effective treatment program of a cleaner disinfectant. For example, while it is known that cranberries have quite a few bioactive constituents, purified forms of particular constituents would likely function even better especially when combined with one or more other compounds to suitably clean and disinfect a surface, for example, The types of compounds in cranberries that are not harmful to humans, but may be used to accomplish the objectives of the cleaner disinfectant include, but are not limited to flavan-3-ols, A-type procyanidins, anthocyanidins, phenolic acids, benzoic acid and ursolic acid.

Flaven-3-ols primarily consist of condensed tannins such as proanthocyanidins, polyflavonoid tannins, catechol-type tannins, pyrocatechollic type tannins, non-hydrolysable tannins or flavolans, as nonlimiting examples, which are polymers formed by the

condensation of flavans. Proanthocyanidins form anthocyanidins, another bioactive constituent of cranberries, when depolymerized under oxidative conditions. A-type procyanidins, in contrast to B-type procyanidins, are known to have substantial bioactivity and they largely pass through the human body without physiological effect. B-type procyanidins (catechin dimers) may be converted to A-type procyanidins by radical oxidation.

Anthocyanidins are found in relatively high concentrations in cranberries. The anthocyanidin family includes glycosides such as cyanidin, peonidin, malvidin, pelargonidin, delphinidin, and petunidin. Glycone, or aglycon, is the compound remaining after the glycosyl group on a glycoside is replaced by a hydrogen atom. The bioavailability and extent of impact on cleaning and/or disinfecting has been found to be affected by the aglycones and glycosidic moieties of the anthocyanidin family compound.

Phenolic acids of cranberries include such compounds as hydroxybenzoic and hydroxycinnamic acids. Very high contents of benzoic acids are found in cranberries. Of course, benzoic acid is abundantly present in other foods, such as, in a non-limiting example, grapefruit juice. Hydroxycinnamic acids are also found in other foods as well.

Grapefruit juice also includes other ingredients that can disinfectant and perhaps clean. For example, while amylase compounds are found in grapefruit juice and are known for their enzymatic function, a certain class of amylase enzymes have been found to inhibit the growth of or eliminate altogether certain classes of pathogens. Similarly, the enzyme pectinase found in grapefruit juice has been found to degrade bacterial biofilms.

Terpenes, such as ursolic acid, are abundantly present in cranberries also. c/.s-3-0-p- hydroxycinnamoyl ursolic acid and lrans-3 -O-p-hydroxyci nnamoyl ursolic acid are two very rare derivatives of ursolic acid and are found in cranberries. The iridoids monoterpene and 6,7-dihydromonotrepein are also found in cranberries. Cranberry juice has also been extracted to find coumaroyl iridoid glycosides 10-p-/ra//.s-coumaroyl- l S-dihydormonotropein and 0-p-cA-coumaroyl-l S-dihydormonotropein. Depside, 2-0-(3,4-dihydroxybenzoyl)- 2,4,6-trihydoxyphenylmethylacetate, has also been found when subjecting cranberry juice. to the same type of bacterial anti -adherence assay.

Flavonols of cranberries include primarily glycosides of quercetin, myricetin, and kaempferol. However, elderberry, when consumed in a processed form, tends to provide a greater concentration of flavonols.

Many edible bioactive constituents are found in foods that may be consumed by humans. Acetic acid, for example, is both found naturally in many fruits such as apples, grapes, oranges, pineapples, and strawberries, and produced by fermentation in the manufacture of vinegar. Citric acid is found in citrus fruits, particularly higher in

concentration in juices of such fruits, including lemons, oranges, and limes. Citric acid is also present in certain berries including strawberries, raspberries, gooseberries, and cranberries, but not blueberries.

While certain ingredient by themselves may not be suitable to meet regulatory requirements because they are not strong enough for a 5 log kill, a combination of these ingredients with other compounds may allow this deficiency to be overcome. Lactic acid is found predominantly in fermented milk-based products otherwise considered sour milk products. Non-limiting examples of fermented milk products that have lactic acid are yogurt, some cottage cheeses, kumis, kefir, and laban. Of course, lactic acid may itself be produced commercially, as many of the other compounds that are sourced from foods, through a manufacturing process. Lactic acid may be commercially produced by fermentation of carbohydrates such as glucose, sucrose, or lactose, or through some other chemical synthesis.

Malic acid is found, particularly at higher concentrations, in apples and watermelon. Malic acid can also be found in apricots, bananas, blackberries, cherries, grapes, kiwi, lychees, mango, nectarines, oranges, peaches, pears and strawberries. Malic acid is generally considered a flavor enhancer contributing to the favorable sour taste of fruits; the exogenous application of malic acid has been found to have certain antioxidative properties.

Fruit and vegetable juices are also known to contain compounds that may function as a bioactive constituent as well. For example, lemon juice may include phenolic and carotenoid bioactive compounds.

Other preservative-based compounds having certain bioactivity may be included in foods. For example, levulinic acid or 4-oxopentanoic acid is an organic compound that is classified as a keto acid. This white crystalline solid is soluble in water as well as polar organic solvents. While levulinic acid may be used in foods as a flavor ingredient, it is a precursor in the manufacturer of a wide number of other products including pharmaceuticals and cigarettes. Levulinic acid, typically in combination with other compounds, has been demonstrated to be a sanitizer in certain food items such as cantaloupes, for example.

While further definitive evidence of bioactivity could be provided, the recitation of the following listing of items should be taken as bioactive compounds that are compatible with human contact, but perhaps themselves individually having some cleaning and/or disinfecting and/or sanitizing effect or some derivative component thereof having such an affect.

Magnesium ascorbyl phosphate, which is vitamin C, is a powerful antioxidant that has shown to retard the formation of melanin or pigmentation by melanocytes on the skin in particular. Menthol has been used as an antiseptic and is known to have beneficial blood circulation properties. Nicotinic acid is a vasodilator that increases blood flow and dilates blood vessels for an immediate pumping effect.

Olive fruit oil is high in vitamins, antioxidants and oleic acid, which may potentially lead to it disinfecting and sanitizing effect. Oregano oil is an anti -bacterial, antiseptic, anti fungal and anti-inflammatory that is clinically proven to kill th _Q Propionibacterium acnes bacteria.

Palmitoyl oligopeptide is an amino acid blend that has been shown to help destroy free radicals that may otherwise promote infection. Panthenol, which is known as vitamin B5, has been shown to stimulate cellular proliferation and acts as an efficient anti

inflammatory agent.

Red marine algae includes iodine, sulfur and amino acid content that demonstrates anti-inflammatory and disinfectant properties. Retinol is the alcohol derivative of vitamin A that may readily metabolize to retinoic acid in a two-step conversion process. Retinoic acid may demonstrate sufficient disinfectant properties. Rose centifolia or cabbage rosewater demonstrates cleansing properties while still proving to be compatible with human contact. Rose oil possesses antiseptic, disinfectant, and slight tonic properties. Rosemary oil is known for its antiseptic properties.

Salicylic acid is considered an antiseptic having a micro-exfoliating action that promotes disinfection. Sandalwood oil is a strong antibacterial and antiseptic agent having reasonably good disinfectant and sanitization properties.

Tangerine oil with its antispasmodic and sedative may itself include components that are relatively good disinfectant species. Tea tree oil is a natural preservative having antiseptic, germicidal and expectorant properties. Tocopheryl acetate, also known a vitamin E, is an antioxidant and free radical scavenger that may promote cleansing, disinfecting and sanitizing of surfaces. Ylang ylang oil acts as a strong cleansing agent.

Bioactive constituents compatible with human contact are not only limited to fruits, vegetables, and herbs, but may be derived from animal or fish sources. For example, chitosan is extracted from crustacean shells and, notwithstanding its many pharmaceutical uses, demonstrates antimicrobial activity against certain pathogens. Relatively recent testing has shown that other marine-derived small molecules from invertebrate and microorganism sources demonstrate biomedical potential.

In an embodiment of the invention, a cleaner disinfectant comprising a material that is found in any one or more of a food and a product intended to be ingested has any one of an anionic surfactant, a nonionic surfactant, and a combination thereof.

In the compositions of the present invention, cleansing is provided by surfactants. Surfactants of the present invention includes any surfactant allowed to be ingested.

Surfactants can also be referred to as wetting agents because they lower the surface tension of the medium in which it is dissolved. In lowering surface tension, the surfactant plays a supporting role in the removal and suspension of undesirable surface materials.

The compositions of the present invention provide mild, eco-friendly, either natural or synthetic surfactants that comprise any one of or a combination of an anionic surfactant and a nonionic surfactant. Anionic surfactants suitable for use in the cleaner disinfectant of the invention include sodium stearoyl lactylate, sodium lauroyl lactylate, and sodium lauryl sulfate also known as sodium dodecyl sulfate. The anionic surfactant for use in the cleaner disinfectant may alternatively or additionally comprise sodium lauroyl sarcosinate

Nonionic surfactants that may be suitable for use in the cleaner disinfectants of the present invention include, for example, sucrose stearate, sucrose laurate, sucrose palmitate, lauryl glucoside, caprylyl/capryl glucoside, inulin lauryl carbamate, decyl glucoside, and alkyl polyglucosides such as coco glucoside. A nonionic surfactant of the invention may include coco-glucoside, which is derived from coconut oil and fruit sugar. Coco-glucoside enables foaming and enhanced viscosity, particularly if used in conjunction with a compound such as glyceryl oleate. Glyceryl oleate is derived from glycerin and oleic acid and functions as an emollient and a thickener. When used alone, coco-glucoside provides a cleansing functionality, but when used in conjunction with glyceryl oleate, the combination of coco- glucoside and glyceryl oleate provides cleansing and other surface conditioning.

A non-ionic surfactant, according to an embodiment of the invention, may additionaly include decyl glucoside that, similar to coco-glucoside, enables loose foaming and enhanced viscosity. Decyl glucoside is produced upon the reaction of glucose from corn starch with the fatty alcohol decanol, which is derived from coconut.

In certain embodiments of the invention, lipoamino acid surfactants are used as an alternative to traditional surfactants. Lipoamino acids comprise a fatty acid component (hydrophobic portion) and an amino acid component (hydrophilic portion). All lipoamino acid surfactants have been found to be biodegradable and as having low toxicity. Foaming polypeptides are a form of lipoamino acid surfactants that are highly functional fatty acid derivatives of hydrolyzed proteins and amino acids. Foaming polypeptides are prepared by reacting hydrolyzed protein with a reactive fatty acid reagent. The fatty acid group is covalently bonded to the polypeptide chain as a result of the reaction. Once the carboxylic acid group is neutralized, a soluble foaming polypeptide is formed.

Lipoamino acid surfactants suitable for use in the cleaner disinfectants of the present invention include sodium cocoyl hydrolyzed wheat protein and sodium cocoyl hydrolyzed soy protein. Compositions of the present invention may contain lipoamino acid surfactants in an amount ranging between 1-20 wt% or a preferred amounts ranging between 2-10 wt%.

In a preferred embodiment of the invention, the cleaner disinfectant includes a combination of at least two of a lactic acid and salt thereof, a lactylated fatty acid salt, an anionic phospholipid, a short chain ester of a fatty acid, a fatty acid and any salt thereof, an alkali metal salt, an alkaline earth metal salt, a carboxylate salt, a sulfate, a sulfonate, a phosphonate, a phosphate, and a sarcosinate.

Cleaner disinfectants of the present invention can include any number of

combinations of ingredients discussed throughout this specification. The concentrations of the ingredients may vary among embodiments of the invention. In certain non-limiting embodiments, for example, the cleaner disinfectants of the invention may include at least about 0.010%, 0.020%, 0.025%, 0.050%, 0.075%, 0.100%, 0.125%, 0.150%, 0.250%, 0.500%, 0.750%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, 4.0%, 5.0%, 6.0%, 7.0%, 8.0%, 9.0%,

10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99% or more, or any range or integer derivable therein, of at least one of the ingredients mentioned throughout the specification and/or claims in weight based upon a total weight of the cleaner disinfectant. In non-limiting aspects, the percentage may be calculated by weight or volume of the total composition. A person of ordinary skill in the art would understand that the concentrations can vary depending on the desired effect of the

An aspect of the invention provides a one-step process for cleaning and disinfecting comprising the steps of applying a cleaner disinfectant to a surface intended to be contacted with food, the disinfectant having a surface active agent; leaving the cleaner disinfectant on the surface without a need for any rinsing; and contacting food on the surface. According to an embodiment of the invention, the cleaner disinfectant includes only one or more of a material that is found in one or more of a food and a product allowed to be ingested.

Accordingly, the surface does not require a rinse step. According to this aspect of the invention, any of the formulations described herein may be used in the one-step process for cleaning and disinfecting an inanimate object such as a surface of this inanimate object.

FIG. l is a flowchart showing the steps in a conventional method of

cleaning/disinfecting a surface. The conventional method of cleaning/disinfecting a surface 1 includes the steps of a cleaning operation 10 followed by a rinsing step 20. A disinfecting operation 30 typically then follows the cleaning operation 10. Another rinsing step 40 follows the disinfecting operation 30.

FIG. 2 is a flowchart showing the steps in another conventional method of cleaning/disinfecting a surface. This conventional method of cleaning/disinfecting a surface 50 includes the steps of removing gros or large debris 60. For example, gros or large debris includes things that may be picked up by hand. Cleaning and disinfecting the surface with a cloth and cleaner/disinfectant 70. Another step in the conventional method of

cleaning/disinfecting a surface includes waiting for at least about 5 minutes 80. The actual time for waiting is determined by the amount of time it takes for the disinfectant to do the work on the surface. The conventional cleaning method for cleaning/disinfecting a surface additionally includes rinsing the surface with water 90.

FIG. 3 is a flowchart showing the steps in a method of cleaning/disinfecting a surface according to an embodiment of the invention. The exemplary embodiment of FIG. 3 shows the steps that may be included in a method of cleaning/disinfecting a surface 100 of the invention including a cleaning/disinfecting operation 110. As shown in FIG. 3, the cleaner disinfectant of the invention reduces the multiple steps required for cleaning and disinfecting a surface compared to that of a conventional operation as shown in FIG. 1, for example. Indeed, FIG. 3 illustrates a one-step process for cleaning and disinfecting a surface using the cleaner disinfectant of the invention. Additional steps that may be included in the method of cleaning/disinfecting a surface 100 of the invention include the cleaner/disinfectant 120 being mixed with a solvent 130 in a mixing operation 140 to form the diluted cleaner/disinfectant solution that is introduced to the cleaning/disinfecting operation 110. In certain embodiments of the invention, the solvent comprises an aqueous-based solvent. In still other embodiments of the invention, the solvent comprises water. Of course, in other embodiments of the invention, the solution having the non-oxidizing disinfectant may come pre-mixed. The solution may comprise up to about 10 wt% of the cleaner/disinfectant based upon an overall weight of the solution. Any of the cleaner/disinfectant concentrations of the invention, as disclosed herein, may be use as the cleaner/disinfectant to clean/disinfect a membrane. As also shown in FIG. 3, a rinsing operation is not required following the cleaning/disinfecting operation using a cleaner/disinfectant of the invention.

FIG. 4 is a flowchart showing the steps in a method of cleaning/disinfecting a surface according to another embodiment of the invention. The exemplary embodiment of FIG. 4 shows the steps that may be included in a method of cleaning/disinfecting a surface 150 of the invention including removing gros or large debris 160, cleaning and disinfecting the surface with a cloth and cleaner/disinfectant 170 and leaving the surface to airdry 180. As shown in FIG. 4, a rinsing operation is not required in the cleaning/disinfecting operation using a cleaner/disinfectant of the invention.

In an embodiment of the invention, the cleaner disinfectant is at least a 0.1 %, at least a 0.25 %, at least a 0.5 %, at least a 0.75 %, at least a 1 %, at least a 2 %, at least a 2.5 %, at least a 5 % dilution, or at least a 10 % dilution of a concentrate all based upon a weight of the cleaner disinfectant. In certain embodiments of the invention, the cleaner disinfectant is a 1 % dilution of a concentrate based upon the weight of the cleaner disinfectant. In certain embodiments of the invention, the cleaner disinfectant in its diluted form has an antimicrobial efficacy that meets the requirements of at least one of, but preferably, both EN1276 at 20°C and EN13697 at 20°C both under dirty conditions. In certain embodiments of the invention, the cleaner disinfectant has a cleaning performance comparable to a standard cleaner disinfectant in a Gardner test.

In an embodiment of the invention, the treatment of the inanimate object meets a European ETnion norm for disinfectant testing EN1276, and/or EN13697

EN 1276 and EN 13697 are the defined test procedures that were used in the evaluation of the performance of the samples in the examples that follow.

The cleaner disinfectant of the one-step process for cleaning and disinfectant may comprise any of the compositions as defined herein.

EXAMPLES

For simplicity and ease of initial testing, screening level performance testing using the EN1276 method under dirty conditions with hard water in five minutes with only

Pseudomonas aeruginosa and Staphylococcus aureus were conducted in this set of experiments. TWEEN® 20 having the synonyms polyethylene glycol sorbitan monolaurate and polyoxyethylene sorbitan monolaurate is available from Sigma-Aldrich now otherwise known as now MilliporeSigma (St. Louis, Missouri, USA). SPAN® 20 having the synonyms sorbitan laurate and sorbitan monolaurate is also available from Sigma-Aldrich.

EXAMPLE 1

Table 1 shows Formulation 1 and the results of the efficacy tests for the Pseudomonas aeruginosa and Staphylococcus aureus bacteria.

Formulations showing the results of the efficacy tests for the Pseudomonas aeruginosa and Staphylococcus aureus bacteria are included in Table 2.

The results for Formulation 1 in Table 1 and Formulations 2-7 in Table 2 demonstrate that a blend of 2.5 wt% fatty acid, with about 1 wt% of sodium dodecyl sulfate in a lactic acid based formulation containing on the order of 25 wt% active lactic acid is required to deliver at least a 5-log reduction against both Pseudomonas aeruginosa and Staphylococcus aureus at a 1 wt% dilution. TABLE 1

In summary, based upon the results in Tables 1 and 2, Formulation 1 provides a preferred level of kill on the tested bacterial species. Comparing the antimicrobial efficacy of Formulation 1 to that of Formulation 2 shows that the fatty acid is necessary for efficacy. Similarly, in comparing the antimicrobial efficacy of Formulation 1 to that of Formulation 3, it is observed that the efficacy of the fatty acid is not due entirely to the capric acid in the blend and that either both the capric and caprylic acids are necessary, or that a total higher concentration of fatty acid is necessary.

Comparing the antimicrobial efficacy of Formulation 1 to that of Formulations 4, 5 and 6 shows that the sodium bisulfate cannot be replaced by glycolic acid without sacrificing efficacy against Staphylococcus aureus. Formulation 7 shows that reducing the level of lactic acid to 20 wt% from 25 wt% active results in a reduction in antimicrobial efficacy to below the target of 5-log for Staphylococcus aureus. EXAMPLE 2

Table 3 shows test formulations and the results of the efficacy tests for the

Staphylococcus aureus bacteria. Given that the formulations in Table 2 showed a greater efficacy against Pseudomonas aeruginosa , it was decided to screen antimicrobial

performance against only Staphylococcus aureus again using the EN1276 test method.

TABLE 3

Test Results

These tests in Table 3 evaluated whether SPAN and TWEEN could be replaced by elevated levels of sodium dodecyl sulfate. Specifically, the SDS level was increased to 15% of a 30% active solution.

Formulation 8 demonstrated less than l-log reduction against Staphylococcus aureus whereas formulation 1 showed greater than 5-log reduction. Formulation 9, based upon a blend of lactic acid and glycolic acids, did not show significant efficacy against

Staphylococcus aureus. Formulation 10, which included low levels of SPAN, TWEEN and propylene glycol, did not demonstrate significant efficacy against Staphylococcus aureus either.

Formulations 11 and 12, with increased concentration of the fatty acid blend, did show greater than 6-log reduction against Staphylococcus aureus. Formulation 13, based upon citric acid instead of lactic acid, showed 3-log reduction against Staphylococcus aureus. Based upon this data, it might be assumed that a blend of citric acid with more than 2.5 wt% of fatty acid would deliver the target 5 -log efficacy against Staphylococcus aureus.

The European registration requires efficacy against the following four different species: Pseudomonas aeruginosa , Staphylococcus aureus , Escherichia coli and

Enterococcus hirae. Also, given the target market for this formulation demonstrating efficacy against listeria is also important, Listeria innocua was used as a surrogate in our laboratories for the more hazardous Listeria monocytogenes . Formulations 14 and 15 were tested against Pseudomonas aeruginosa , Staphylococcus aureus , Escherichia coli ,

Enterococcus hirae and Listeria innocua with the results shown in Table 4.

TABLE 4

At 1 wt% use concentration both Formulations 14 and 15 passed all organisms tested except for Enterococcus hirae. Without intending to be bound by the theory, Enterococcus hirae is a lactic acid bacteria and so the fact that a lactic acid based formulation failed to demonstrate sufficient kill is perhaps not surprising.

Formulation 14 was also tested at 2 and 3% use concentrations. Sufficient kill was in fact observed at 3% use concentration. A variation of Formulation 14 containing 7.5 wt% fatty acid vs 5.0 wt% demonstrated an efficacy against Enterococcus hirae of 4.66, 7.69 and 7.694og reductions at 1, 2 and 3% formulation dilutions, respectively, using the EN1276 test method.

The difference between Formulations 14 and 15 is the presence of propylene glycol as a stabilizer. While this has no significant effect upon antimicrobial performance in the EN1276 test, the propylene glycol appears to have a slight impact upon stability. Both formulations show stability at room temperature but storage in an oven at 50°C shows separation, marginally worse in the absence of propylene glycol. ETpon cooling to room temperature, both samples homogenized with a little agitation. Thus, the use of propylene glycol for stability is preferred in certain embodiments of the invention.

EXAMPLE 3

Formulation 16 was tested against Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Enterococcus hirae and Listeria innocua with the results shown in Table 5.

Table 5 indicates that Formulation 16 passes the EN1276 and ENI13697 tests for Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Enterococcus hirae and Listeria innocua at 1 wt% use dilution.

Table 5 also indicates that Formulation 16 passes the EN13697 test for

Staphylococcus aureus , Enterococcus hirae and Listeria innocua at 1 wt% and passes this same test for Pseudomonas aeruginosa and Escherichia coli at only 0.5 wt% use dilution under dirty conditions in hard water at 5 minutes.

EXAMPLE 4

The relative cleaning performance of a formulation may be measured by using the formulation to clean tiles soiled with a standard composition soil using a Gardner abrasion tester running a fixed number of cycles. As those skilled in the art will readily recognize, the results of the Gardner test will be dependent upon the exact soil composition being used. Typical soil compositions include protein, starch, lipids and carbon black to improve soil visualization. TABLE 5

A standard test method using the Gardner abrasion tester well known in the art was used to test certain Formulations of the invention. A Formulation 16 analog, prepared using raw materials classified as equivalent but not identical, due to their origin (European vs North American suppliers), was prepared and cleaning performance was measured vs tap water alone and vs D 10, a commercial product available in Europe from Diversey, Inc. The results are given in Table 6. Water was defined to have 0 % relative cleaning while D10 has 100 % relative cleaning, and water having a relative deposition of 31 % and D10 having a relative deposition of 0 %.

TABLE 6

The cleaning performance of the Formulation 16 analog at 1 wt% dilution without rinse is significantly better than the use of water alone, and comparable to that of the positive control. The redeposition performance of the prototype formulation is significantly better than with the use of water alone, and again comparable to that obtained with the positive control.

EXAMPLE 5

Table 7 shows a test formulation that has additionally proven effective in efficacy tests.

TABLE 7

As the composition for Formulation 17 demonstrates, the combination of caprylic acid/capric acid of the previous formulations may be replaced by a combination of caprylic acid and glycolic acid. Table 8 shows two additional formulations that include caprylic acid instead of the caprylic acid/capric acid combination.

Formulation 18 slightly reduces the amount of caprylic acid included in the formulation. Formulation 19 does not include glycolic acid. Formulation 19 would seem to be indicative of the need to include an additional acid in combination with a lactic acid and one of caprylic acid and capric acid. TABLE 8

Table 9 compares Formulations 16, 17, 18 and 19.

Comparing Formulations 16 and 19 of Table 9, the difference is only 0.4 wt% lactic acid and caprylic acid vs the blend of caprylic and capric acid at the same concentration, yet there is a very significant difference in the antimicrobial performance. While this is evidence that while both caprylic acid and the caprylic / capric acid blend will work to give antimicrobial performance, the longer chain capric acid is beneficial and improves performance.

Similarly, comparing Formulations 17 and 19 of Table 9, the difference is only 0.4 wt% lactic acid and 3.0 wt% glycolic acid, yet again there is a significant difference in the antimicrobial performance. This appears to offer evidence that the glycolic acid will boost the performance of the caprylic acid. Formulations 16 and 17 have similar performance in spite of the difference in fatty acids, but, without intending to be bound by the theory, this is likely due to the caprylic acid based Formulation 17 also containing glycolic acid.

TABLE 9

19

Formulations 20, 21, 22 and 23 are additional variations on the combinations of lactic acid and caprylic acid. As shown in Table 10, these formulations also include glycolic acid.

TABLE 10

EXAMPLE 5

Table 11 shows yet another test formulation in an embodiment of the invention that has additionally proven effective in efficacy tests. TABLE 11

Table 11 compares the compositions of Formulation 24 having caprylic acid to Formulations 25 and 26, which are substantially free of a caprylic acid. At 1 % dilution in water, each of these formulations pass the EN1276 disinfection test at room temperature.

Many modifications and other embodiments of the invention set forth herein will come to mind to one skilled in the art to which this invention pertains having the benefit of the teachings presented in the descriptions herein. It will be appreciated by those skilled in the art that changes could be made to the embodiments described herein without departing from the broad inventive concept thereof.
