    [0001] [001] The present invention is directed to antimicrobial compositions, such as personal care compositions, having improved antimicrobial effectiveness and high foam attributes. More particularly, the present invention relates to antimicrobial compositions that exhibit the antimicrobial efficacy of the cationic active ingredients, a foam surfactant, a chelating agent, a new foam reinforcing copolymer, with the optional properties of a broad spectrum of effectiveness antimicrobial, high foam and reduced irritation for mammalian tissues. The composition is essentially free of aromatic biocides, such as triclosan, anionic surfactants and C1 to C4 alcohols. BACKGROUND OF THE INVENTION
    [0002] [002] Antimicrobial personal care compositions are known in the art. Especially useful are antimicrobial cleaning compositions, which are typically used to clean the skin and to destroy bacteria and other microorganisms present on the skin, especially on the user's hands, arms and face.
    [0003] [003] Antimicrobial compositions are used, for example, in the healthcare industry; long-term care, hospitality and health / fitness facilities; service food industry, meat processing industry, and in the private sector by individual consumers. The widespread use of antimicrobial compositions indicates the place of important importance in the control of bacteria and other populations of microorganisms in the skin. It is important, however, that antimicrobial populations provide a substantial and broad-spectrum reduction in populations of microorganisms quickly and without problems associated with toxicity and skin irritation.
    [0004] [004] In particular, antimicrobial cleaning compositions typically contain an antimicrobial active agent, an anionic surfactant for cleaning and foaming, skin conditioning agents for cosmetic effects, and optional dyes, perfumes, and thickening agents, such as clays, polymers, cellulosic derivatives, or colloids, for aesthetic purposes, all in an aqueous vehicle.
    [0005] [005] Several different classes of antimicrobial agents have been used in antimicrobial cleaning compositions. These include active ingredients selected from the following classes: phenolic compounds, carbanalide compounds, lower alcohols, surface active halogens, and carboxylic acids. Each of these classes has its own unique advantages and challenges. Examples of specific anti-microbial agents include PCMX (xylenol parachloromethane), Triclosan, Triclocarban, benzyl alcohol, quaternary ammonium compounds (QAC), and iodine and iodine complex biguanides (for example, chlorhexidine diglyconate). Triclosan is currently the dominant antimicrobial active ingredient in the dermal cleansing market.
    [0006] [006] Although there is a growing consumer demand for products that have both an activity against bacteria and other microorganisms, there is an even greater demand to meet consumers' expectations regarding their level of concern with certain biocides, such as Triclocarban and Triclosan .
    [0007] [007] Triclosan is disadvantaged as an antimicrobial agent due to the persistence of health and environmental concerns due to the possible formation of the intermediate and / or the environment by products. Thus, there is a need for an effective personal care antimicrobial composition that is substantially free of biocides such as Triclosan and Triclocarban but that still provides a high level of foam desired by consumers and is gentle on the skin. The present invention is directed to such antimicrobial compositions.
    [0008] [008] The aforementioned disadvantages of current antimicrobial compositions are addressed by embodiments of the present invention and will be understood by reading and studying the following specification. The following synthesis is made by way of example and not by way of limitation. It is only provided to assist the reader in understanding some aspects of the invention. SUMMARY OF THE INVENTION
    [0009] [009] In accordance with the present invention, a composition that exhibits rapid cidal efficacy and high foam attributes is provided. The antimicrobial composition comprises a cationic active ingredient, a foam reinforcing surfactant, which may include nonionic surfactants, cationic or amphoteric surfactants, a new foam copolymer, increasing to a chelating agent, a foam and water stabilizer. The present antimicrobial compositions are free of the antimicrobial agent triclosan (i.e., 2,4,4'-trichloro-2'hydroxy-diphenyl ether), anionic surfactants and C1 to C4 alcohols and have rapid cidal efficacy. The compositions also provide abundant stable foam and can optionally contain ingredients to increase skin compatibility and skin health.
    [0010] [010] Therefore, an aspect of the present invention is to provide an antimicrobial composition to reduce the microbial population in dermal tissue, the antimicrobial composition comprising: .. (A) about 0.1% by weight to about 10.0 % by weight, by weight of cationic active agents; (B) about 0.1% by weight to about 20% by weight, by weight of a reinforcing foam surfactant; (C) about 0.5% by weight to about 25% by weight of adjuvant dermis (d) about 0.05% by weight to about 12.0% by weight, of a foam polymer increasing, ( e) about 0.1% by weight to about 10% by weight of a foam stabilizer, (f) from about 0.1% by weight to about 6.0% by weight of a chelating agent such that the chelating agent forms a complex calcium-chelating agent with a stability constant (expressed in logarithmic form) greater than 5.5 e (g) of water or another suitable diluent in which the composition is essentially free of triclosan, anionic surfactants and C1 to C4 alcohols.
    [0011] [011] Another aspect of the present invention is to provide an antimicrobial composition to reduce the microbial population in dermal tissue that is stable and has a pH of about 4.0 to about 9.0. The present composition also has excellent aesthetic properties, such as foam and abundant stability foam and can optionally contain ingredients to increase skin compatibility and skin health. In addition, the composition may have reduced potential for tissue irritation.
    [0012] [012] An additional aspect of the present invention is to provide products for personal use based on an antimicrobial composition of the present invention, for example, a skin cleanser, a surgical cleaner, a gel hand cleaner, a disinfectant, antiseptic washing, and the like.
    [0013] [013] A further aspect of the present invention is to provide a method for reducing gram positive bacteria and / or gram negative populations on mammalian tissues, including human tissue, by contacting tissue, such as the dermis, with a composition of the present invention for a sufficient time, such as about 15 seconds to 5 minutes, to reduce the bacteria level to a desired level. Antimicrobial efficacy is applicable to viral and fungal organisms, as well as gram negative and gram positive bacteria

    [0046] [046] The cationic active ingredients are an antimicrobial agent useful in the present invention. Cationic or cationically active ingredients are nitrogen-based active cationic portions with positive net change. The cationic or cationically active ingredients are preferably selected from the group consisting of cationic polymers, cationic surfactants, cationic monomers, cationic silicone compounds, cationic-derived protein hydrolysates and betaine with at least one cationic or cationically active group.
    [0047] [047] Suitable cationic active ingredients contain quaternary ammonium groups. Suitable cationic active ingredients include especially those with the general formula: N (+) R1R2R3R4X (-) wherein R1, R2, R3 and R4 independently of each other, represent alkyl groups, aliphatic groups, aromatic groups, alkoxy groups, polyoxyalkylene groups, starch groups, hydroxyalkyl groups, aryl groups, H + ions, each with 1 to 22 carbon atoms, with the proviso that at least one of the groups R1, R2, R3 and R4 has at least eight carbon atoms and where X (-) represents an anion, for example, a halogen, acetate, phosphate, alkyl nitrate or sulfate, preferably a chloride of.

    [0049] [049] In accordance with an important feature of the present invention, a composition of the present invention is substantially antimicrobial free of triclosan. The phrase "substantially free" of triclosan is defined as meaning that the composition contains from 0% to about 0.25% by weight, in total, of triclosan. In particular, triclosan can be present in an antimicrobial composition in a total amount of 0.25% or less, either as a by-product or as a component of an ingredient in the composition, but triclosan is not intentionally introduced into the composition.
    [0050] [050] Triclosan is disadvantaged as an antimicrobial agent due to environmental and health concerns, due to the possible formation of the intermediate and / or the environment by products. Foam boosting surfactant
    [0051] [051] In addition to an antimicrobial agent and a surfactant derived from quaternized sugar, the present antimicrobial composition to reduce the microbial population in the skin tissue of a mammal of the present invention also contains one or more reinforcing foam surfactants.

    [0055] [055] The antimicrobial composition may contain a nonionic surfactant component that includes an amount of nonionic surfactant detergent or a mixture of nonionic surfactants. Typically, a nonionic surfactant has a hydrophobic region, such as a long chain alkyl group or an alkylated aryl group, and a hydrophilic group comprising an ethoxy and / or other hydrophilic moieties. As defined herein, a "non-ionic foam-raising surfactant" has a hydrophobic region having an alkyl group containing six to eighteen carbon atoms, and an average of one to about twenty ethoxy / propoxy or moieties. Examples of ionic foam-increasing surfactant non-coagents include, but are not limited to, alkyl amine oxide, alkyl amine ether oxide, alkyl alcohol alkoxylates, aryl alcohol alkoxylates, substituted alcohol alkoxylates, non-ionic copolymer blocks, copolymers non-ionic heteric, alkanolamides, or polyethoxylated esters of glycerin, and mixtures thereof.

    [0132] [0132] (A) Determination of time of death activity: The activity of antimicrobial compositions was measured by the time of death method [ASTM E 2315 Standard Guide for Evaluation of Antimicrobial Activity Using a Kill Time Procedure], by which survival of challenged organisms exposed to an antimicrobial composition test is deterred as a function of time. In this assay, a diluted aliquot of the composition is brought into contact with a known population of test bacteria for a specified period of time at a specified temperature. The test composition is neutralized at the end of the time period, which traps the composition's antimicrobial activity. The percent or, alternatively, login reduction of the initial bacterial population is calculated. In general, the method of killing time is known to those skilled in the art. In addition, comparative data on the foam profile of representative systems is shown.
    [0133] [0133] (B) The composition can be tested at any concentration from 0 to 100%.

All tests if performed in triplicate, the results are combined, and the average log reduction is reported.
    [0134] [0134] (C) The choice of the contact time period is also at the discretion of the investigator. Any period of contact time can be chosen. Typical contact times range from 15 seconds to 5 minutes, with 30 seconds and 1 minute being typical contact times. The contact temperature can also be any temperature, usually room temperature, or about 25 degrees Celsius.
    [0135] [0135] (D) The microbial suspension, or test inoculum, is prepared by growing a microbial culture on any suitable solid support (for example, agar). The microbial population is then washed from the agar with sterile saline and the microbial population of the suspension is adjusted to about 108 colony-forming units per ml (cfu / ml).
    [0136] [0136] (E) The table below lists the test microbial cultures used in the following tests and includes the name of the bacterium, in the ATCC (American Type Culture Collection) the identification number, and the abbreviation of the name of the organism used hereinafter .
    [0137] [0137] S. aureus is a Gram positive bacterium, whereas E. coli is a Gram-negative bacterium.
    [0138] [0138] The log reduction is calculated using the formula:
    [0139] [0139] Log reduction = log10 (number control) - log10 (survivors of the test sample). High Foam Determination
    [0140] 1. Prepare uma solução de 1% do produto em água de grãos 5. 2. Encher 150 mL da solução em um misturador 3. Misture em velocidade média de 10 segundos. 4. Despeje em um copo de 1000 mL e meça a altura de espuma. 5. Meça a altura de espuma aos 3 e 5 minutos. [0140] The height of the foam was determined with the following procedural steps: 1. Prepare a 1% solution of the product in grain water 5. 2. Fill 150 mL of the solution in a mixer 3. Mix at an average speed of 10 seconds. 4. Pour into a 1000 mL cup and measure the height of foam. 5. Measure the foam height at 3 and 5 minutes.
    [0141] [0141] Foam stability was determined by the difference between foam / air interference and the foam / aqueous interface 5 minutes after pouring a 1% solution into a 1000 mL beaker. In vitro irritation determination
    [0142] [0142] In vitro irritation was assessed by an external testing facility using "EpiDerm MTT ET-50 Protocol (EPI-200)" from Matek Corporation.
    [0143] [0143] The test consists of a topical exposure of the clean test chemical to a model of reconstructed human epidermis (RHE) followed by a cell viability test. Cell viability is measured by the conversion of MTT dehydrogenase [(thiazol 3-4,5-dimethyl-2-yl) 2,5-diphenyltetrazolium bromide], present in the cellular mitochondria, to a blue formazan salt that is quantitatively measured after extraction from tissues. Reducing the viability of tissues exposed to chemicals compared to negative controls (treated with water) is used to predict the potential for skin irritation.
    [0144] [0144] The epidermis tissues are conditioned by incubating related compounds to release transport to stress and overnight debris. After pre-incubation, the tissues are exposed topically to the test chemicals for 60 minutes. Preferably, three tissues are used for Assay chemistry (TC) and for the positive control (PC) and negative control (CN). The tissues are then carefully rinsed, dried to remove the test substances, and transferred to fresh media. The tissues are incubated for 42 hours. Then, the MTT assay is performed by transferring the tissues to 24-well plates containing MTT medium (1 mg / ml) after an MTT incubation for 3 h, the blue formazan salt formed by the cellular mitochondria is extracted with 2, The ml / isopropanol tissue and the optical density of the extracted formazan is determined using a spectrophotometer at 570 nm. Relative cell viability is calculated for each tissue as% of the mean of the negative control tissues. Skin irritation potential of the test material is predicted, if the remaining relative cell viability is less than 50%. Determination of Foam Strength
    [0145] [0145] Foam resistance was determined by measuring 65 grams of the test product in a mixer and mixing for about 10 seconds at medium speed. After that, the test solution was poured into a cylinder and a plastic ball was dropped into the test solution and times to determine the number of seconds required for the plastic ball to fall from a first pre-level. determined to a second predetermined level, for example, from 100 mL mark on the cylinder to the 40 mL mark on the cylinder. Example 1
    [0146] [0146] The following figures show the efficacy data of the present antimicrobial composition, using various cationic active ingredients, sugar-derived surfactants and foam quaternary boosting optional surfactants.
    [0147] [0147] Table 7 and Figure 1 (log death of Cationic active ingredients): The following figures illustrate the effectiveness after a 30-second exposure time of three different cationic active ingredients, specifically 0.5% Quat (Benzalkonium chloride ), 2% CHG (chlorhexidine gluconate), and 1% PHMB (polyhexamethylene biguanide) in a representative surfactant system.
    [0148] [0148] Table 7 illustrates the formulas for the three cationic active ingredient systems tested. Both the surfactant derived from quaternary sugar and foam boost surfactant were kept constant and only the cationic active ingredient was changed between the three tests performed. The results are illustrated in Figure 1.
    [0149] [0149] As shown in Figure 1, all three cationic active ingredients had high cidal activity against S. aureus and E. coli bacteria within an exposure time of 30 seconds.
    [0150] [0150] In Table 8 and Figure 2 (log death of Quaternary Sugar Derivative Surfactants): Next, the applicants tested the efficacy against S. aureus and E. coli bacteria with increasing concentrations of sugar-derived surfactants, specifically quaternary, poly (chloride) Trimoniumhydroxypropyl Cocogluocosides. The amount and type of cationic active ingredient (0.5% ADBAC Quat) and foam boost surfactant (1.95% alkyldimethylamine Oxide) was kept constant. Table 8 below illustrates the quantitative results of this test and Figure 2 illustrates the graphical results.
    [0151] [0151] As in Table 8 and Figure 2 illustrate, the surfactant derived from quaternary sugar has a high cidal activity against S. aureus and E. coli bacteria after only 30 seconds of exposure. In addition, the tolerance of the quaternary derived sugar surfactant against bacteria is shown. In addition, it is clearly illustrated that an increase in the concentration of quaternary sugar-derived surfactant maintains a good record of killing bacteria up to a 1 to 4 ratio of cationic quaternary sugar-derived surfactant to active ingredients.
    [0152] [0152] In Table 9 and Figure 3 (log death of foam Surfactant Boosting): Table 15 and Figure 3 illustrate the effectiveness with increasing concentrations of foam surfactants by increasing, specifically, amine oxide. The amount and type of cationic active ingredient (0.5% ADBAC Quat) and sugar-derived Quaternary surfactant (1.25% Poly Trimoniumhydroxypropyl Cocoglucosides Chloride) were kept constant. Table 9 below illustrates the quantitative results of this test and Figure 3 illustrates the graphical results.
    [0153] [0153] As Table 9 and Figure 3 illustrate, the foam reinforcing surfactant has a high cidal activity against S. aureus and E. coli bacteria after only 30 seconds of exposure. In addition, the tolerance of the foam to boost surfactant against bacteria is shown. In addition, it is clearly illustrated that a wide range of booster surfactant foam maintains a good record of killing bacteria.
    [0154] [0154] Figure 4 (Softness Index for a Dermal Antimicrobial Purifier Embodiment): Applicants have tested the dermal irritation (smoothness) of the preferred embodiment for a Dermal Antimicrobial Purifier, as illustrated in Table 12, to four commercially available antimicrobial soaps . Commercially Available Products A, C and D are available from Medicated Gojo, Akron, Ohio and commercially available Product B is available through Dial a subsidiary of Henkel Corporation, Dusseldorf, Germany. As illustrated in Figure 4, the antimicrobial dermal cleaning product of the present invention has a high relative softness index especially compared to commercially available antimicrobial soaps.
    [0155] [0155] Figure 5 (Foam profile of a Dermal antimicrobial cleanser Embodiment): Applicants tested the foam profile of the preferred embodiment for a Dermal antimicrobial cleanser, as illustrated in Table 12 for three commercially available antimicrobial soaps. As illustrated in Figure 6, the antimicrobial dermal cleaner of the present invention has both a good foam volume and foam stability, especially in comparison with antimicrobial soaps that are commercially available.
    [0156] [0156] Table 10 and in Figure 6 (The efficacy of cationic assets in combination with surfactants derived from Quaternary sugar and alkyl dimethyl amine oxide): Applicants have tested the efficacy against S. aureus and E. coli with various derivative surfactants of quaternary sugars, kept constant at 1.25%. The amount and type of cationic active ingredient (0.5% ADBAC Quat) and foam boost surfactant (1.95% alkyldimethylamine Oxide) was kept constant.
    [0157] [0157] As Table 10 illustrates, a high log kill is maintained against S. aureus and E. coli bacteria for both surfactants derived from quaternized sugars and surfactants derived from polyquaternized sugars. The chain length of the quaternary sugar surfactant can be modified and still maintain high efficiency. The graphic results of the test are illustrated in Figure 6.
    [0158] [0158] Table 11 and Figure 7 (Foam Stiffness Comparison): Applicants have tested the foam stiffness of an embodiment of the present invention for use in dermal applications, as shown below in Table 11, in comparison with two commercially available products, the commercial products of E and F. Commercial Products and and F are anionic washes based on traditional dermal surfactants containing an active cationic. Commercial Product E is commercially available from Proctor & Gamble, Cincinnati, Ohio and commercial product F is commercially available from Deb Group Limited, United Kingdom, England. The results of the foam stiffness test are illustrated in Figure 7. As shown in Figure 7, the stiffness of the dermal wash foam of the present invention is greater than cationic active dermal washes commercially available with a traditional anionic surfactant base. Foam stiffness formula of the current invention (pH 5.5 to 7.5):
