SANITIZING COMPOSITIONS AND PROCEDURES FOR DISINFECTING SURFACES TECHNICAL FIELD The present invention relates to antimicrobial compositions that can be used to disinfect and clean various surfaces, including animated surfaces (eg, human skin, mouth and the like) and inanimate surfaces that include but are not limited to such hard surfaces. walls »tiles» table tops »glass» bathroom surfaces »kitchen surfaces» dishes »as well as fabrics» clothes »carpets and the like.

BACKGROUND The antimicrobial / antibacterial compositions include materials that have the ability to disinfect. It is generally recognized that a de-fecting material greatly reduces or even eliminates the microorganisms »for example» bacteria »that exist on a surface. Compositions based on halogen-containing compounds such as hypochlorite or based on quaternary compounds have been extensively described in the art for disinfection purposes. The compositions comprising peroxide bleach are also known as de-active compositions.

However »the compositions comprising hydrogen peroxide as the sole microbial agent» typ > at a level of 7% by weight of the total composition "are not fully satisfactory when used under typical diluted conditions" eg "at a dilution level of 1:50 (comsition: water) to disinfect surfaces slightly soiled »for example» surfaces that have been previously cleaned with a conventional detergent and still have some residual organic and / or inorganic soils. In addition »the presence of organic and / or inorganic soils decreases the bactericidal activity of many antimicrobial compounds such as peroxygen bleach» thus resulting in a lower bactericidal / disinfectant activity capacity of the compositions comprising them. Thus, it is an object of the present invention to provide compositions that provide excellent disinfection on poorly soiled surfaces even when used under highly diluted conditions. It has now been discovered that this can be achieved by combining different anti-microbial ingredients with each other »that is» by combining a peroxygen bleach »with a betaine or sulphobetaine surfactant» or derivatives thereof or mixture thereof »with an antimicrobial compound selected from the group consisting of anti-i crobial essential oils or active agents thereof (eg »thymus!» eugenol and the like) »paraben» glutaraldehyde and mixtures thereof. More particularly, it has now been discovered that a composition comprising said peroxygen bleach, said betaine or sulphobetaine surfactant and said anti-microbial compound, provides excellent disinfection on lightly soiled surfaces even under highly diluted conditions, ie, up to a dilution level of said composition.water of 1: 100. An advantage of the present invention is that excellent disinfection is provided under mildly soiled conditions over a wide range of bacterial strains "including Gram positive and Gram negative bacterial strains" but also more resistant microorganisms such as fungi. Another advantage of the compositions of the present invention is that apart from the disinfection properties supplied, an adequate cleaning performance is also provided. Likewise »the compositions according to the present invention are suitable for use on all types of surfaces» including animated surfaces (for example, human skin and / or mouth »when used as an oral preparation or toothpaste), as well as inanimate surfaces. In fact »this technology is particularly suitable in applications for hard surfaces» as well as in laundry applications »for example, as a laundry detergent or laundry additive in a so-called" soaking mode ", "mode during washing" or even co or a laundry pre-cleaner in a "pre-treatment mode". More particularly, the compositions according to the present invention are suitable for being used safely on surfaces of the "including those surfaces in contact with food and / or babies. In fact, when the compositions according to the present invention are used under diluted conditions, the amount of chemical residues left on a surface disinfected therewith is reduced. Thus, it may not be necessary to rinse a hard surface, for example, after the compositions of the present invention have been applied thereto under diluted conditions. A further advantage of the compositions of the present invention is that they can be provided in different forms, eg, in liquid form, packaged in a conventional detergent bottle, or in sprayable or foamed form packed in a spraying jet. foam "or in the form of rags incorporating said composition, or in a non-liquid form. EP-B-288 S89 discloses a hard surface liquid comprising effective antimicrobial amounts of pine oil and at least one oil soluble organic acid. No other antimicrobial compounds are mentioned »much less a peroxygen bleach. EP-241390 discloses that textiles contaminated with bacteria can be disinfected by first treating them with a detergent and then with a peroxide bleaching agent in an aqueous bath at pH 9-13 in the presence of non-combined calcium. No other microbial ingredients are described. Document EU-4,4? 4,191 describes that percompounds such as onopersulfate have bactericidal, fungicidal and virucidal properties. Document EU-4 »404» 191 discloses that compositions comprising onopersulfate can be used in diluted form to treat hard surfaces. However, no other anti-microbial ingredients are mentioned. EP-A-667 392 discloses hard surface cleaning compositions comprising hydrogen peroxide and a surfactant / thickener component comprising a chemoresulfate surfactant together with amine or betaine oxide. The compositions of that document have a pH of 7 to 0. No other antimicrobial compounds are described and fewer essential oils or active agents thereof parabens or glutaraldehyde. The document EU-5 »403» 587 discloses aqueous antimicrobial compositions which can be used for cleaning »disinfecting and cleaning hard surfaces. More particularly »document EU-5» 403,587 discloses aqueous compositions (pH 1 to 12) comprising essential oils (0.02% to 5%) »which exhibit efficacy in the antimicrobial properties» such as oil of toillo, oil of eucalyptus , clove oil and the like »and a sufficient solubilizing or dispersing agent to form an aqueous solution or dispersion of said essential oils in an aqueous vehicle. Said compositions may further comprise other antipycrase ingredients such as phenolic compounds and quaternary ammonium compounds, however, no betaine or sulfobetaine surfactants or peroxygen bleaches are disclosed. EU-5,398,749 describes compositions for inhibiting the growth of aerobic microorganisms including bacteria and fungi, said compositions including an oxidant and glutaraldehyde. The oxidants can be selected from the group of chlorine »bromo» monopersulfate, perborate, hydrogen peroxide, peracetic acid and percarbonate. It is mentioned that the oxidant exhibits a synergistic effect when added to glutaraldehyde.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the disinfectant compositions comprise a peroxygen bleach, a betaine or sulphobetaine surfactant and an anti-microbial compound selected from the group consisting of anti-microbial essential oils or active agents thereof, paraben, glutaraldehyde, and mixtures thereof "with the exception of aqueous compositions comprising hydrogen peroxide at a level of 0.5% to 50% by weight of the total composition, and from 0.001% to 10% by weight of a terpene alcohol. "cyclic terpene alcohol" or ester thereof, as said unique antimicrobial compound. The compositions in accordance with the present IO invention can be formulated as either liquid or non-liquid (for example »in the form of gel or paste, or in solid form» such as powder or granulate). In case the compositions are formulated as solids they will be mixed with a suitable solvent, typically water, before use. In liquid form, the compositions are formulated preferably, but not necessarily, as aqueous compositions. Liquid compositions are preferred here for reasons of convenience of use. As an essential element. the compositions according to the present invention comprise a peroxygen bleach or mixtures thereof. The preferred peroxygen bleach is hydrogen peroxide or a water-soluble source thereof, or mixtures thereof. It is more preferred to use hydrogen peroxide in the compositions according to the present invention. It is thought that the presence of said peroxygen bleach. especially hydrogen peroxide, persulfate and the like »in the compositions of the present invention» contributes to the disinfecting properties of said compositions. In fact, said peroxygen bleach can attack the vital function of the microorganism's cells, for example, can inhibit the assembly of ribosome units within the cytoplasm of the microorganism cells. Likewise, said peroxygen bleach such as hydrogen peroxide "is a strong oxidant that generates free hydroxyl radicals that attack proteins and nucleic acids. Furthermore, the presence of said peroxygen bleach * especially hydrogen peroxide "provides strong stain removal benefits that are particularly noticeable" for example "in laundry and hard surface cleaning applications. As used herein, a "hydrogen peroxide source" refers to any compound that produces hydrogen peroxide when said compound is in contact with water. Suitable water-soluble sources of hydrogen peroxide for use herein include percarbonates, persic esters, persulfates such as onopersulfate. perborates and peroxides such as diperoxydodecandioic acid (DPDA) »peristaltic magnesium acid» and mixtures thereof. In addition, other classes of peroxides can be used as an alternative for hydrogen peroxide and hydrogen peroxide sources or in combination with hydrogen peroxide and sources thereof. Suitable groups include dialkyl peroxides, diacperoxides, preformed percarboxylic acids, organic and inorganic peroxides and / or hydroperoxides. Typically, the compositions herein comprise at least 0.01% by weight of the total composition of said peroxygen bleach or mixtures thereof, preferably from 0.1% to 15%, and more preferably from 1% to 10%. As a second essential ingredient, the compositions according to the present invention comprise a betaine or sulfobetaine surfactant, or derivatives thereof or mixtures thereof. It is speculated that said anomeric surfactants have a double action. In fact, they facilitate disinfection, increasing the permeability of the bacterial cell wall, thus allowing other active ingredients to enter the cell. In the same way, said tensile agents contribute to the cleaning performance of the compositions herein. Moreover »due to the moderate action profile of said betaine and / or sulfobetaine surfactants, the compositions herein may be particularly suitable for cleaning delicate surfaces, ie» delicate laundry or surfaces in contact with food and / or or babies. The betaine and / or sulfobetaine surfactants are also extremely gentle to the skin, and thus contribute to the convenience of using the compositions of the present invention. The betaine and sulfobetaine surfactants suitable for use in the compositions of the present invention are the betaine / sulfobetaine and betaine type detergents, in which the molecule contains both basic and acidic groups which form an internal salt which gives the molecule cationic and anionic hydrophilic groups on a wide range of pH values. Some common examples of these detergents are described in the patents of E.U.A. Us. 2,082,275, 2,702,279 and 2,255,082"incorporated herein by reference. The preferred betaine and sulfobetaine surfactants have the formula: R2 | R 1 - - - (CH 3) n - Y - 1 R 3 wherein R 1 is an alkyl radical containing from 1 to 24 carbon atoms, preferably from 8 to 18, and more preferably from 12 to 14, wherein R 2 and R 3 they contain from 1 to 3 carbon atoms, and preferably 1 carbon atom, wherein n is an integer from 1 to 10, preferably from 1 to G, and more preferably is 1. And is selected from the group consisting of carboxyl and sulfonyl radicals, and wherein the sum of the radicals R 1 and R 3 is from 14 to 24 carbon atoms, or mixtures of the isos. Examples of particularly suitable betaine surfactants include C12-C18 aldimeti Ibetaine. just like the cocobetai a. and alkyl 1d eti 1 C10-C16 betaine, such as 1-auri-1-betaine. Cocobetaine and lauryl 1 are commercially available from Seppic and Albright & Wilson respectfully. under the tradename of Amonyl 2S5R and Empigen BB / L ", respectively. Typically, the compositions herein comprise at least 0.005% by weight of the total composition of said betaine or sulfobetaine surfactant or derivatives thereof or mixtures thereof. of the same »preferably from 0.01% to 10%» and more preferably from 0.1% to 5% As the third essential ingredient »the compositions according to the present invention comprise an antimicrobial compound or mixtures thereof. selects from the group consisting of antimicrobial essential oils "or active agents thereof, paraben, glutaraldehyde, and mixtures thereof Preferred antimicrobial compounds for use herein are antimicrobial essential oils or active agents thereof Suitable antimicrobial essential oils to be used in the compositions herein are those essential oils that exhibit activity antimicrobial By "active agents of antimicrobial essential oils" is meant here any ingredient of essential oils exhibiting antimicrobial activity. It is speculated that said antimicrobial essential oils and active agents thereof act as protein denaturing agents. Similarly, said antimicrobial essential oils and active agents thereof are naturally occurring compounds that contribute to the safety profile of the compositions of the present invention when used to disinfect any surface. An additional advantage of the presence of said antimicrobial oils and active agents thereof is that they impart a pleasant odor to the disinfectant compositions of the present invention without the need to add a perfume. In fact, the disinfectant compositions according to the present invention provide not only excellent disinfecting properties on the slightly soiled surfaces that will be disinfected, but also a good aroma. These essential oils include »but are not limited to» those obtained from thyme »lemon grass» citrus »lemons» oranges »anise» clove »anise seed» cinnamon »geranium» roses, mint »lavender, citronella, eucalyptus» mint, camphor, sandalwood, cedar, and mixtures thereof. The active agents of essential oils that will be used herein include but are not limited to »thymus! (present »for example» in thyme) »eugenol (present, for example» in cinnamon), menthol (present »for example» in mint) »geranium! (present »for example» in geranium or rose), verbenone (present, for example, in vervain) »eucalyptus! and pinocarvone (present in eucalyptus) »cedrol (present» for example »in cedar), anethole (present, for example» in anise) »carvacrol, hinoquitiol» berberine »terpineol» limonene, rotania, and mixtures thereof . The active agents of essential oils that are preferred to be used here are thymus! Eugenol, verbenone, eucalyptus! »Limonene and / or geranium !. The scam! may be available commercially »for example» from Aldrich »and eugenol may be commercially available» for example »from Sigma 1S Systems-Bi oindustries (SBI) -Manheimer Inc. The suitable paraben to be used in the compositions herein includes and il-arabene »methylparaben» propylparaben »or mixtures thereof. The glutaraldehyde can be commercially available from Union Carbide or from BASF. Typically, the compositions herein comprise at least 0.003% by weight of the total composition of said antimicrobial compound, or mixtures thereof of preferably from O.OOS% to 4%, more preferably from O.% to 2%. It has now been discovered that improved disinfection is provided by the compositions of the present invention on slightly soiled surfaces "even at high dilution levels" ie up to a dilution level of said co-position: ag? A of 1: 100 . By "lightly soiled surfaces" we mean here surfaces that are contaminated by residual amounts of organic and / or inorganic soils in an amount that is equivalent to a water solution of 0.03 g / 1 of bovine albumin and hard water (see the cleaning conditions of the European standard prEN 127S, CEN / TC 21S N59, 3.3 »4 of 11/95). As a result, a surface which is badly soiled can be, for example, any surface that has been cleaned / washed with a conventional detergent composition and which further needs to be disinfected. By "improved disinfection" it is herein intended that the compositions of the present invention comprising said peroxygen bleach, said betaine or sulphobetaine surfactant and said anti-microbial compound selected from the group consisting of antimicrobial essential oils or active agents of the same, paraben. glutaraldehyde, and mixtures thereof »allow reducing the amount of bacteria on a lightly soiled surface» compared to the same compositions without said peroxygen blancher and / or said betaine or sulphobetaine surfactant »or the same compositions without said antimicrobial compound , especially when used in diluted form. In fact »excellent disinfection is obtained on several microorganisms that include Tram positive bacteria such as Staphylococcus aureus, and Gram negative bacteria such as Pseudomonas aeruginosa. as well as on fungi such as Candida albicans, present on slightly soiled surfaces. The disinfecting properties of a composition can be measured by the bactericidal activity of said composition. A suitable test method for evaluating the bactericidal activity of a composition is described in European Standard prEN 1276, CEN / TC 216 N 59, November 1995, issued by the European Committee for the Normal, Brussels. European Standard prEN 1276, CEN / TC 216 N 59 specifies a test method and requirements for the minimum bactericidal activity of a disinfectant composition. The test is accepted if the bacterial colonies that form units (cfu) are reduced from 10"cfu (initial level) to 10 cfu (final level after coming into contact with the disinfectant product), that is, a reduction of The viability of the compositions according to the present invention pass this test under light soiling conditions, even if they are used in highly diluted conditions Another suitable test method for evaluating the bactericidal activity of the present compositions on lightly soiled surfaces, especially hard surfaces, is AFNOR T72-190R and T72-301R The compositions according to the present invention formulated in liquid form can be applied in pure form Preferably, the compositions according to the present invention apply to the the surface to be disinfected, in its diluted form, by "form d luida" it is tried here to say that the compositions of conformity In the present invention, which are in liquid form or in solid form can be diluted by the user with a liquid, typically water. Said compositions can be diluted by the user typically up to 100 times their weight of water, preferably 80 to 40 times their weight of water, and more preferably 60 to 30 times. Accordingly, the present invention also encompasses dilute disinfectant compositions obtainable by diluting a composition in accordance with the present invention in water. In the preferred embodiment of the present invention, wherein said compositions are aqueous liquid compositions, said aqueous compositions preferably have a pH no greater than 12, preferably from 3.5 to 7, and more preferably from 4 to 5. The pH of the compositions can be adjusted using organic acids such as citric acid »succinic acid, acetic acid» aspartic acid, lactic acid and the like »or inorganic acids» or alca agents! inizantes. The compositions of the present invention may further comprise any surfactant known to those skilled in the art "including nonionic, anionic, cationic, zwitterionic surfactants and / or other amphoteric surfactants other than betaine and / or sulfobetaine. mentioned above. Said surfactants are convenient herein as they contribute to the cleaning performance of the present compositions. Typically, the compositions according to the present invention comprise up to 50% by weight of the total composition of another surfactant or mixtures thereof above said surfactants of betaine and / or sulfobetaine, preferably from 0.3% to 30%. and more preferably from 0.4% to 25%. Other amphoteric surfactants suitable for use herein include amine oxides or mixtures thereof. Amine oxides are preferred herein because they further contribute to the disinfecting properties of the compositions herein. In fact »they facilitate the disinfection by breaking the membrane of the cell wall of the bacteria» allowing other antimicrobial agents to enter the cell and attack »for example» the internal part of it. Amine oxides suitable for use herein have the following formula R 1 R 2 R 3 NO, wherein each of R 1 and R 3 is independently a straight or branched saturated hydrocarbon chain containing from 1 to 30 carbon atoms. Amine oxides suitable for use in accordance with the present invention are the a-oxides having the following formula R ^ R ^ R ^ -O, where R 1 is a hydrocarbon chain containing 1 to 30 carbon atoms »preferably from S to 20» more preferably from S to 14! and very preferably from 8 to 10 carbon atoms "and wherein R 2 and R 3 are linear or branched hydrocarbon chains or independently substituted or unsubstituted containing from 1 to 4 carbon atoms, preferably from 1 to 3 carbon atoms , and more preferably are met lo groups. R1 can be a straight or branched and saturated hydrocarbon chain. The amine oxides which are preferred to be used here are, for example, the C8-C10 amine oxides of the natural mixture, as well as the C12-16 amine oxides commercially available from Hoechst. In a preferred embodiment of the present invention, wherein the compositions herein are particularly suitable for the disinfection of a hard surface, the surfactant is typically a surfactant system comprising an amine oxide and a betaine surfactant or a surfactant. sulfobetaine »preferably at a weight ratio of amine oxide: betaine or sulfobetaine of 2: 100: 1, more preferably from 6: 1 to 100: 1, and most preferably 10: 1 to 50: 1. use of said surfactant system in the compositions herein suitable for disinfecting a hard surface provides effective cleaning performance and provides gloss on the cleaned surfaces, ie the amount Film / scratch formation left on the cleaned surface that has been treated with said compositions »is minimal. The compositions herein may also preferably comprise an anionic surfactant or mixtures thereof. Particularly suitable anionic surfactants which will be used herein include the water-soluble salts or acids of the formula R0S03M "wherein R is preferably a hydrocarbyl of C ^ - ^^ f, preferably an alkyl or hydroalkyl having an alkyl component of Z '^ zo' more preferably an alkyl or hydroalkyl of CT-C d5. and M is H or a cation, for example »an alkali metal cation (for example» sodium, potassium »lithium)» or ammonium or substituted ammonium (for example »methyl-» dimethyl- and trimetio-onium cations, and quaternary ammonium cations »such as cations of tetramethyl ammonium and dimethylpiperidinium; and quaternary ammonium cations derived from al quines "such as ethylamine, diethyl tin, triet lamina" and mixtures thereof and similes). Other anionic surfactants suitable for use herein include those with 1-difeni-1-ether sulfonates and alkylcarboxylates. Other anionic surfactants may include salts (including »for example» sodium »potassium» ammonium and substituted ammonium salts such as mono- »di- and triethanolamine salts) soap» linear alkylsulfonates of Cs-C20, alkanesulphonates primary or secondary of Cß-C22, ol fi nsul fonatos of ß-C .-. ^ »sulfonic acid polypic acids prepared by sulfonation of the product piro! The addition of alkaline earth metal citrates, for example, as described in British Patent Specification No. 1,082,179, Alkyl Icopyl ether-Cß-Cz-ether sulfates, (containing up to 10 moles of ethylene oxide); alkyl ether sulfonates such as methyl estersulmates of Ci4-C1 < _; Acryl glyols sulfonates, oleic acid glycol sulfates, ethylene oxide ether sulfates of alkylphenol. paraffinsulfonates, alkylphosphates, isethionates such as acyl isethionates, N-acyl taurates, succinamates and sulfosuccinates, sulfosuccinate monoesters (especially saturated and unsaturated Ca -> -C 3 saturated esters) sulfosuccinate distearates (especially C3-C ^ saturated or unsaturated diesters) »acyl sarcosinates» alkylpol saccharide sulfates such as the alkyl sulfates Ipol glucoside (the non-sulphonated nonionic compounds being described below) »branched primary alkalisulfonates» alkyl ethoxycarboxylates such as those of the formula RO (CH2CH20) ^ Ha OO- ^ "wherein R is an alkyl of Ca-C22 > K is an integer from 0 to 10, and M is a soluble salt-forming cation. Resin acids and hydrogenated resin acids are also suitable, such as rosin, hydrogenated rosin, and hydrogenated resin acids and resin acids present in tallow oil derivatives. Additional examples are given in "Surface Active Agents and Detergents" (Vols. I and II by Schwartz, Perry and Berch). A variety of such surfactants are also generally described in the US patent. No. 3,929,678, issued December 30, 1975 to Laughlin et al., Column 23, line 58 to column 29 »line 23. The anionic surfactants which are preferred to be used in the compositions herein are the C8 alkyl sulphonates. -C16, CS-C16 alkyl sulfates, C8-C16 alkoxyalkyl alkylsulphates (for example, C8-C16 ethoxylated alkyl sulphates), and mixtures thereof. Such anionic surfactants are preferred here because they have been found to further contribute to the disinfecting properties of a disinfectant composition herein. For example, C8-C16 alkyl sulfate acts by disrupting the cell membrane of bacteria, inhibiting enzymatic activities, disrupting cell transport and / or denaturing cellular proteins. Indeed, it is speculated that the improved disinfection performance is associated with the addition of an anionic surfactant, especially a C8-C16 alkylsulphonate, a C8-C16 alkylsulfate and / or a C8-C16 alkoxylated alkylsulfate; for example »in a composition of the present invention» will probably multiply the mode of attack of said surfactant against bacteria. Thus, another aspect of the present invention is the use of an anionic surfactant, especially a C8-C16 alkylsulfonate, a C8-C16 alkyl sulfate and / or an alkoxylated alkylsulphate of CB-C16. in a disinfectant composition of the present invention for improving the disinfecting properties of said composition on Gram negative and / or Gram positive bacteria. Suitable nonionic surfactants to be used herein are the ethoxylated and / or propoxylated fatty alcohols which are commercially available with a variety of fatty alcohol chain lengths and a variety of degrees of ethoxylation. In fact, the HLB values of said alkoxylated nonionic surfactants depend essentially on the length of the fatty alcohol chain, the nature of the alkoxylation and the degree of alkoxylation. Surfactants catalogs are available which list a number of surfactants, including nonionic surfactants, together with their respective HLB values. Particularly suitable for use herein as nonionic surfactants are non-ionic hydrophobic surfactants having a HLB (hydrophilic-lipophilic balance) below 16, preferably below 15 and more preferably below 14.
