The present invention relates to the disinfection of surfaces with a liquid disinfecting composition comprising a hydrogen peroxide, an antimicrobial essential oil, and a shear thinning polymeric thickener.
Description
ROCLABLE DISINFECTANT COMPOSITIONS AND PROCEDURE TO SANITIZE SURFACES WITH THE SAME
TECHNICAL FIELD
The present invention relates to sprayable liquid compositions suitable for disinfecting animated surfaces, for example, human skin or inanimate surfaces including hard surfaces, walls, tiles, table surfaces, bathroom surfaces, kitchen surfaces, as well as fabrics, clothes and carpets. .
BACKGROUND OF THE INVENTION
The antimicrobial compositions include materials that have the ability to disinfect. It is generally recognized that a disinfectant material greatly reduces or even eliminates microorganisms that exist on a surface. Compositions based on halogen-containing compounds such as hypochlorite or quaternary compounds have been extensively described in the art for disinfection purposes. Compositions comprising peroxygenated bleaches are also known as disinfectant compositions. WO88 / 00795 is representative of the prior art, and discloses liquid disinfectant compositions comprising a compound selected from the group of organic acids, perborates, perishes and their salts, together with other antimicrobial compounds such as a quaternary ammonium salt and an oil essential. However, said disinfectant compositions are not completely satisfactory for the consumer, who is looking for an effective disinfectant composition that can be easily used in various disinfection applications, for example, in sprayable form, in a safe manner for the consumer and the environment. In fact, a disadvantage associated with said disinfectant compositions based, for example, perished, is that they can damage the surfaces on which they are put in contact to carry out their disinfecting action. In fact, said peracid-based disinfectant compositions are perceived by consumers as unsafe for various surfaces, including hard surfaces or fabrics. Therefore, an object of the present invention is to provide effective disinfectant compositions even when used in highly diluted conditions, which are convenient for use by the consumer and safe for the surface and the environment. It has now been discovered that this can be achieved by providing a liquid and sprayable disinfectant composition comprising a hydrogen peroxide, an antimicrobial essential oil and a polymeric thickener thinning thickener. More particularly, it has been found that the liquid compositions containing hydrogen peroxide of the present invention and comprising said antimicrobial essential oil and poiimeric shear thinning thickener, exhibit improved safety for the surface treated therewith, while providing effective disinfection performance on clean surfaces, i.e., surfaces that are free of any organic and / or inorganic soils, even at high dilution levels, i.e. at dilution levels of up to 1: 100 (composition: water). In addition, it has been found that the liquid and spray compositions containing hydrogen peroxide of the present invention comprising said antimicrobial essential oil and polymeric shear thinning thickener exhibit improved safety for the user after use, compared to the same. compositions without said polymeric thickener for shearing thinning. In fact, an advantage of the liquid compositions of the present invention is that the inhalation of said compositions by the user is avoided or diminished, when said compositions are applied on a surface that will be disinfected by means of a spray dispenser. In this way, the compositions herein allow to avoid potential health problems such as irritation of the nose and / or throat and / or cough or even damage to the lungs., which could otherwise occur from the inhalation of a mist or haze of hydrogen peroxide that could be formed by spraying on a surface a composition containing hydrogen peroxide and free of said polymer thickener from shear thinning. A further advantage of the present invention is that irritation and / or damage to the eyes when spraying a liquid composition according to the present invention on a surface to be disinfected is also avoided. Another advantage of the present invention is that liquid compositions comprising hydrogen peroxide, an antimicrobial essential oil and a polymeric thickener thinning agent are easily applied on the surface to be disinfected by means of a spray dispenser (v. ., a manually operated trigger dispenser). In fact, said compositions result in a shear thinning behavior to facilitate their application, that is, said compositions are thinner at higher shear rates. In this way, said compositions easily pass through the pumping mechanism of a spray dispenser where the shear rate is high and immediately afterwards recover their thickened character when they reach the surface to be treated and adhere to it. Likewise, the life time of a spray dispenser head is extended, that is, the shear thinning behavior of said compositions avoids the obstruction of said head. Another advantage of the present invention is that liquid and sprayable disinfectant compositions can be uniformly applied to a relatively large area of a surface that will be disinfected by means of a spray dispenser, thereby ensuring effective disinfection performance. In fact, effective disinfection performance is provided over a wide range of pure bacterial strains including Gram positive and Gram negative bacterial strains, and more resistant microorganisms such as fungi. Another advantage of the compositions of the present invention is that apart from the disinfection properties provided, a suitable cleaning is also provided, especially in the embodiment of the present invention in which the compositions herein further comprise a surfactant or a mix of it. Likewise, the compositions according to the present invention are suitable for use on all types of surfaces, including animated surfaces such as human skin or mouth (e.g., as an oral preparation or toothpaste), as well as inanimate surfaces such as hard surfaces, and in laundry applications, e.g., as a laundry detergent, laundry additive or even pretreatment for laundry. More particularly, an advantage of the compositions according to the present invention is that they are suitable for use on delicate surfaces, including those surfaces in contact with food and / or babies, in a safe manner. Moreover, when the compositions according to the present invention are used under diluted conditions, the amount of chemical residues left on the surfaces is reduced. In this way, it may not be necessary to rinse, for example, a hard surface after said compositions have been applied thereto in diluted conditions.
BRIEF DESCRIPTION OF THE INVENTION
The present invention encompasses a liquid and sprayable disinfectant composition comprising hydrogen peroxide, an antimicrobial essential oil and a polymeric thickener thinning agent. The present invention further encompasses a method for disinfecting a surface, wherein a liquid composition as described herein is sprayed onto said surface. The present invention also encompasses a liquid disinfectant composition as described herein, packaged in a spray dispenser.
DETAILED DESCRIPTION OF THE INVENTION
The liquid and sprayable disinfectant compositions As an essential element, the compositions according to the present invention comprise hydrogen peroxide. It is believed that the presence of hydrogen peroxide in the compositions of the present invention contributes to the disinfecting properties of said compositions. In fact, hydrogen peroxide can attack the vital function of the microorganism's cells, for example, they can inhibit the accumulation of ribosome units within the cytoplasm of the microorganism's cells. Likewise, hydrogen peroxide is a strong oxidant that generates hydroxyl free radicals that attack proteins and nucleic acids. In addition, the presence of hydrogen peroxide provides strong stain removal benefits that are particularly noticeable, for example, in laundry and / or hard surface applications. Typically, the compositions herein comprise of
0. 01% to 15% by weight of the total composition of hydrogen peroxide, preferably from 0.5% to 10% and most preferably from 0.8% to 8% As a second essential ingredient, the compositions according to the present invention comprise an essential oil antimicrobial, or a mixture thereof. Typically, the compositions herein comprise at least 0.001% by weight of the total composition of said antimicrobial essential oil, or mixtures thereof, preferably from 0.006% to 10%, most preferably from 0.02% to 4% and more preferably from 0.04% to 2% The antimicrobial essential oils suitable for use in the compositions herein are those essential oils that exhibit antimicrobial activity. It is speculated that said antimicrobial essential oils act as protein denaturing agents. Likewise, said antimicrobial oils are compounds of natural origin that contribute to the safety profile of the compositions of the present invention when they are used to disinfect any surface. An additional advantage of said antimicrobial essential oils is that they impart a pleasing 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 clean surfaces that will be disinfected, but also a suitable aroma while being safe for the surfaces. Suitable antimicrobial essential oils for use herein include, but are not limited to, oils obtained from thyme, citrus, lemons, oranges, anise, cloves, anise seed, cinnamon, geranium, roses, mint, spearmint, lavender, citronella, eucalyptus, mint, camphor, sandalwood, cedar, rosmarin, pine, vervain grass, ratanias and mixtures thereof. It is particularly preferred to use here eucalyptus oil, thyme oil, clove oil, cinnamon oil, geranium oil, eucalyptus oil, peppermint oil, peppermint oil and mixtures thereof. As a third essential ingredient, the compositions according to the present invention comprise a polymeric slimming shear thinner or a mixture thereof. By "polymeric thickener for shear thinning" is meant herein a polymer that can be dissolved or dispersed in a water-based product, and once it is dissolved or dispersed it is capable of thickening said product, said product having different viscosities at different shear stresses. In other words, thanks to the presence of said polymer, the higher the shear stress, the less viscous the product will be. These polymeric slimming shear thinners perform a double function when they are incorporated into the liquid compositions according to the present invention, said function being not only to prevent or diminish the inhalation by the user of said liquid composition when this be sprayed on the surface to be disinfected, but also provide an increased contact time of the composition on vertical surfaces, thus reducing the risk of the composition dripping. Polymeric slimming shear thinners suitable for use herein include synthetic and natural polymers. Polymeric shear thinning thickeners suitable for use herein include polyurethane polymers, polyacrylamide polymers, polycarboxylate polymers such as polyacrylic acids and sodium salts thereof, xanthan gum or derivatives thereof, alginate or a derivative therein, polysaccharide polymers such as substituted cellulose materials such as ethoxylated cellulose, carboxymethylcellulose, hydroxymethylcellulose, hydroxypropylcellulose, hydroxyethylcellulose and mixtures thereof. The polymeric slimming thickeners which are preferred to be used in the compositions of the invention are xanthan gum or derivatives thereof, sold by the Kelco division of Merck under the trade names KELTROL®, KELZAN AR®, KELZAN D35®,
KELZAN S®, KELZAN XZ® and the like. Xanthan gum is an extracellular polysaccharide from Xanthomonas campestras. Xanthan gum is made by fermentation based on corn sugar or other corn by-product sweeteners. Xanthan gum comprises a base structure chain of poly beta- (1-4) -D-Glucopyranosyl, similar to that found in cellulose. Aqueous dispersions of xanthan gum and their derivatives exhibit remarkable rheological properties. Xanthan gum exhibits high pseudoplasticity, that is to say, over a wide range of concentrations a rapid thinning by shear stress occurs which is generally understood as instantaneously reversible. Preferred xanthan materials include the interlaced xanthan materials. The xanthan polymers can be entangled with a variety of known covalent reaction crosslinking agents that react with the hydroxyl functionality of large polysaccharide molecules and can also be entangled using divalent, trivalent or polyvalent metal ions. Such entangled xanthan gels are described in the US patent. No. 4,782,901, which is incorporated by reference herein. Suitable crosslinking agents for xanthan materials include metal cations such as AI +, Fe + 3, Sb + 3, Zr + 4 and other transition metals, etc. The known organic crosslinking agents can also be used. The interlaced xanthan agent which is preferred in the invention is KELZAN AR®, a product of Kelco, a division of Merck Incorporated. KELZAN AR® is an interlaced xanthan agent that provides a thixotropic composition that can produce fog or large particle spray when sprayed. The xanthan gum or derivatives thereof are physically and chemically stable in the hydrogen peroxide containing compositions of the present invention. Said xanthan gum or derivatives thereof are also preferred due to its high solubility in water, and its safety profile with humans and the environment. The polycarboxylate polymers for use herein preferably have a molecular weight of 500,000 to 4,500,000, preferably 1,000,000 to 4,000,000. The polymers most preferred to be used herein contain from 0.5% to 4% by weight of an entanglement agent, wherein the entanglement agent tends to connect linear chains of the polymers to form the resulting entangled products. Suitable entanglement agents include polyalkenyl polyethers. Polycarboxylate polymers include polacrilate polymers. Other monomers than acrylic acid can be used to form these polymers, including monomers such as maleic anhydride, which acts as a source of additional carboxylic groups. The molecular weight per carboxylate group of the monomers containing a carboxylate group typically ranges from 25 to 200, preferably from 50 to 150, most preferably from 75 to 125. Other monomers may also be present in the monomer mixture, if desired, such such as ethylene and propylene, which act as diluents. The polycarboxylate polymers that are preferred to be used herein are the polyacrylate polymers. Commercially available polymers of the polyacrylate type include those sold under the trade names Carbopol®, Acrysol® ICS-1, Polygel® and Sokalan®. The most preferred polyacrylate polymers are the copolymer of acrylic acid and alkyl acrylate (C5-C10), commercially available under the tradename Carbopol® 1623, Carbopol® 695 from BF Goodrich and the copolymer of acrylic acid and maleic anhydride, commercially available under the trade name Polygel® DB of 3V Chemical company. Mixtures of any of the polycarboxylate polymers described hereinbefore may also be used. The compositions according to the present invention comprise from 0.005% to 10% by weight of the total composition of a polymeric slimming shear thinner or mixtures thereof, preferably from 0.01% to 5% by weight, most preferably 0.02% to 2% by weight and more preferably from 0.02% to 1%.
It has now been discovered that a sprayable liquid composition comprising hydrogen peroxide, an antimicrobial essential oil and a shear thinning polymeric thickener exhibits improved safety on surfaces, e.g., on hard surfaces and / or on fabrics, and a Effective disinfection performance on clean surfaces, avoiding or decreasing at the same time the inhalation of said composition by the user when said composition is sprayed on the surface to be treated by means of a spray dispenser. The improved security for the surface is provided with the sprayable liquid compositions of the present invention, in comparison, for example, with the same compositions with a peracid in place of said hydrogen peroxide. In fact, the color damage, e.g., the change and / or discoloration observed when treating colored fabrics with a sprayable liquid composition according to the present invention comprising hydrogen peroxide, said antimicrobial essential oil, is reduced. said polymeric thickener for shearing thinning, while providing an effective disinfection performance on said fabrics, in comparison with the color damage observed when using, for example, the same composition but with a peracid instead of said peroxide. hydrogen. Furthermore, it has been found that the sprayable liquid compositions containing hydrogen peroxide of the present invention and comprising said antimicrobial essential oil and said polymeric slimming shear thinner exhibit improved safety after use, avoiding or decreasing their inhalation by of the user while being sprayed on the surface to be treated, in comparison with the same compositions without said poiimeric thickener thickener. In fact, the incorporation of said polymeric thinning shear thickener in the presently sprayed compositions comprising hydrogen peroxide and an antimicrobial essential oil, allows the formation of mist while being sprayed on a surface in which the droplets / particles formed liquids measure at least partially not less than 10 microns. The safety for the surface can be evaluated on surfaces such as fabrics, by measuring the tensile strength of said fabrics. The tensile strength of a fabric can be measured using the Stress Resistance method. This method consists of measuring the tensile strength of a certain fabric by stretching it until it breaks. The force, expressed in Kg, necessary to break the fabric is the "Ultimate Stress Resistance", and can be measured with the "INSTRON Stress-Force Machine." Effective disinfection performance is obtained with the compositions of the present invention in a variety of microorganisms including Gram-positive bacteria such as Staphylococcus aureus, and Gram-negative bacteria such as Pseudomonas aeroginosa, as well as fungi such as Candida albicans, present on clean surfaces, ie, any surface that is substantially free of organic soils and / or inorganic, even if they are used under highly diluted conditions, eg, up to a dilution level of 1: 100 (composition: water) 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 on clean surfaces is described be in the European Standard prEN 1040, CEN / TC 216 N 78, November 1995, issued by the European Committee for the Normativity, Brussels. European Standard prEN 1040, CEN / TC 216 N 78, specifies a test method and requirements for the minimum bactericidal activity of a disinfectant composition. The test is passed if the bacterial colony forming units (cfu) are reduced from a 107cfu (initial level) to a 102cfu (final level after contact with the disinfectant product), that is, a reduction of 105 viability is necessary. The compositions according to the present invention pass this test, even if they are used under highly diluted conditions. The particle size of the liquid droplets present in the breathing zone of a potential user after the simulated delivery of a sprayable liquid composition according to the present invention from a trigger-activated bottle can be defined by the following test method. The particle size distribution of the aerosol that passes through a simulated breathing zone can be determined using a model that simulates the conditions of consumer use. The human simulation model can be adapted from Mokler (see in particular American Industrial Hygiene Association Journal (40), 330-346, 1979). The particle size distributions of the sprayable liquid compositions can be measured using inertial impact devices (Andersen and Mercer impactors). The compositions according to the present invention are liquid compositions that include aqueous or non-aqueous compositions. Preferably, the liquid compositions herein are aqueous compositions having a pH as such of not more than 12, preferably 2 to 10 and most preferably 3 to 9. The pH of the compositions can be adjusted using organic or inorganic acids, or alkalizing agent. The compositions according to the present invention are physically stable, i.e., that phase separation does not occur when stored in rapid aging tests (RAT) at 50 ° C for 10 days, and / or that phase separation does not occur during Freeze-thaw cycles, that is, heating at 50 ° C and cooling the compositions to 4 ° C three times in 3 days.
