Description

COMPOSITION AND DISPENSER OF SPRAY IN SPRAY TO ELIMINATE SMELLS IN THE AIR Cross reference to related applications The present application is continued in part of the U.S. patent application serial number 1 1 / 476,243, filed on June 28, 2006, which is related to U.S. Provisional Application No. 60 / 694,439, filed on June 28, 2005, and claims the priority benefit of it. FIELD OF THE INVENTION The present disclosure relates to an aerosol spray composition for removing odors and cleaning the air, in combination with a spray valve, and spray performance parameters to provide optimum dispersion of the composition in the surrounding air . Background of the invention Various compositions are available to hide odors in the air. Additionally, various compositions are available to clean the air and eliminate odors from it. These compositions can be dispensed by various spray devices, including aerosol dispensers. Aerosol dispensers have been commonly used to dispense personal, household, industrial and medical products, and to provide a low cost and easy method of dispensing.

Use to dispense a liquid product. Typically, aerosol dispensers include a container, which contains a liquid product to be dispensed. A propellant is used to discharge the liquid from the container. The propellant, which may be a mixture, typically has a boiling point slightly below room temperature, so that, under pressure, the propellant exists as a balance between a vapor phase and a liquid phase. The vapor phase of the propellant provides sufficient force to eject the liquid product from the package when a user activates a discharge valve by, for example, pressing an activating button. When the valve is closed and the container is sealed again, the vapor phase of the propellant is replenished by the liquid phase as the equilibrium between the vapor and liquid phases is re-established within the container. As illustrated in Figure 3, a conventional aerosol dispenser generally includes a container (not shown) for containing a liquid product and a propellant, and a valve assembly (104) for selectively dispensing a liquid product from the container. The valve assembly (104) includes a mounting container (106), a mounting gasket (108), a valve body (110), a valve stem (112), a rod seal (114), a cover of activator (116) and a return spring (118). The valve stem (112), the rod seal (114), and the return spring (118) are positioned within the valve body (110) and are moveable relative to the valve body (110) to selectively control the supply of the liquid product. The valve body (110) is fixed to the underside of the mounting container (106), so that the valve stem (112) extends therethrough, and projects outwardly from the mounting container (106) . The activator cap (116) is attached to the part projecting outwardly of the valve stem (112), and is provided with an activator hole (132). The activator orifice (132) directs the spray of the liquid product to the desired spray pattern. A dip tube (120) is attached to the bottom part of the valve body (110) to supply the liquid product to the valve assembly (104) for dispensing. The entire valve assembly (104) is sealed to a container by means of the mounting gasket (108). During operation, when the activator cap (116) of the dispenser is pressed, the impeller drives the liquid product up the immersion tube (120) and into the interior of the valve body (110) through a body orifice (122). . Inside the valve body (110), the liquid product can be mixed with additional propellant supplied to the valve body (110) through a steam inlet (124). The steam intake (124) helps to mix the liquid product and the propellant inside the valve body (110), in order to break the product into smaller particles for dispensing. The product is propelled from the valve body (110) through a stem hole (126), to the exterior of the valve stem (112), and through an activator hole (132) formed within the activator cover. (116).

A propellant used to drive liquid product from an aerosol container using the valve assembly (1 04) of Figure 3 can be a Series B propellant having a propeller pressure of 275.79 KPa (40 psig) (B-). 40), at 21 .1 1 ° C (70 ° F) (2,722 atm at 294,261 K). "Propellant pressure" refers to the approximate vapor pressure of the propellant, as opposed to "vessel pressure," which refers to the initial pressure of a pressure gauge contained within a full aerosol container. In order to effectively dispense the liquid product, the valve assembly can have a bore hole diameter of 2x0.508 mm (2x0.020"), ie, two bore holes of 0.508 mm (0.020") in diameter , a diameter of steam intake of 0.508 mm (0.20"), a diameter of body hole of 1.524 mm (0.060"). A currently known aerosol air cleaner contains hydrocarbon propellant in an amount of about 29.5% by weight of the contents of the dispenser assembly together with 6 to 8.8% by weight of glycol and pure alcohol solvent, without the presence of water. The hydrocarbon propellants are considered volatile organic compounds (VOC). VOC content in aerosol air cleaners has the potential to require regulation by federal and / or state regulatory agencies, such as the Environmental Protection Agency (EPA) and the California Board of Air Resources (CARB) . One way to reduce the VOC content in such aerosol air cleaners is to reduce the content of propellants of hydrocarbon used to dispense the liquid product. However, a reduction in the content of propellant can adversely affect the performance of the product. Specifically, reducing the propellant content in the aerosol air cleaner can result in an excess product remaining within the package at the end of the life of the dispenser assembly (product retention) and an increase in the particle size of the product. dispensed product (increased particle size). It is desirable to minimize the particle size of a dispensed product in order to maximize the dispersion of the particles in the air, and to prevent said particles from "raining" or "falling" out of the air. For this reason, an aerosol dispenser assembly that can satisfactorily dispense an aerosol product should include a desirable level of propellant to provide high quality product performance throughout the life of the dispenser assembly. The "life of the dispenser assembly" is defined in terms of the pressure inside the container (ie, the can pressure), so that the life of the dispenser assembly is the period between when the pressure inside the container is at its initial level (typically a maximum) and when the pressure inside the container has been substantially finished, that is, it is equal to the atmospheric pressure.

The use of the terms "clean" and "disinfect" used here is consistent with the Disinfectant Scientific Technical Sections (DIS-TSS) numbers 01, 08, 1 1 and 1 3 of the United States Environmental Protection Agency (EPA). (http://www.epa.gov/oppad001/sciencepolicv.htm). For example, with regard to hard surface cleaning products, DIS-TSS-01 requires that a product labeled "disinfectant" be tested with sixty carriers, each with three different samples (for a total of 1 80 samples), which represents three different lots, one of which is at least 60 days old, against Salmonella Choleraesuis (ATCC 1 0708 - negative Gram) or Staphylococcus Aureus (ATCC 6538 - positive Gram). Under DIS-TSS-01, to support a product declaration as "disinfectant" on the label, the product should provide a complete elimination in 59 of the 60 carriers with a 95% confidence level. For this reason, under the DIS-TSS-01, a complete elimination is required essentially to be able to declare effectiveness as "general disinfectant" on the label or to place representations that the product is effective against a broad spectrum of microorganisms, including gram-positive and gram-negative bacteria. In contrast to "disinfect" and the requirements of DIS-TSS-01, which refer to a complete elimination of bacteria on a test surface (hard), the term "clean" refers to a less complete elimination of bacteria in the air. EPA regulations currently prohibit labeling statements as "disinfectant" in cleaning products used in the air, which reduce aerial bacteria, and yet do not provide complete removal of all bacteria in the air. In fact, the EPA imposes separate requirements for use on the "cleaner" label for air (DIS-TSS-1 1). The DIS / TSS-1 1 applies to products with label declarations regarding the reduction of aerial microorganisms or bacteria. The glycol vapors have shown ability to produce significant reductions in numbers of viable aerial bacteria within enclosed spaces. Aerosol formulations, including glycols (triethylene glycol, dipropylene glycol and orpropylene glycol) in concentrations of 5% or higher, will temporarily reduce the numbers of aerial bacteria when adequate amounts are dispensed into a room. Unlike what happens with the DIS-TSS-01, standards or specific methods for evaluating air cleaners in DIS-TSS-1 1 have not been adopted or incorporated. For this reason, it has been known to use certain glycols in aerosol compositions to clean the air in a room by reducing the presence of aerial bacteria that are often a source of bad odors. It has been found that a particular glycol, triethylene glycol ("TEG"), is particularly effective in cleaning the air when it is supplied by means of an aerosol spray. Commercially successful OUST® air cleaning products use a mixture containing approximately 6% by weight of TEG. TEG has also been used as a treatment to eliminate tobacco smoke from the air. There is a need for an aerosol composition and a Improved aerosol dispenser, by which the aerosol composition effectively controls airborne microorganisms and odors, and has a low total VOC content, and by means of which the aerosol dispenser supplies the composition to ambient air with a desired particle size and spray rate to improve cleaning performance. Brief Description of the Invention The present disclosure relates to an aerosol spray composition for removing odors and cleaning the air, in combination with a spray valve, activator and spray performance parameters to provide optimum composition dispersion. in the air. Specifically, the aerosol composition results in aerial particles that are sufficiently small for the composition to be distributed as a mist or fine dispersion, in order to provide sufficient contact with odors and / or bacteria to provide rapid absorption of the bad smells. The particle size of the composition is controlled through the selection valve and the activator dimensions together with specific requirements of the composition, including propellant contents ranging from about 10 to about 50% by weight. The described aerosol compositions include at least one low molecular weight polyol, ie, a polyol having a molecular weight of about 250 or less.

A particularly effective class of polyols that can be included in the aerosol composition described are the glycols. Preferred low molecular weight polyols are monoalkylene glycol, dialkylene glycol and trialkylene glycol or glycerol. The ideal polyol is triethylene glycol (TEG), used by itself or with propylene glycol. Aqueous solutions of polyols are sometimes difficult to effectively dispense in the form of an aerosol. Shooting sprays are also generally not efficient, since the particle size may not be sufficiently controlled due to the homogeneity of the mixture, preventing separation of the polyol from it during evaporation. The description provides an oil emulsion above two phases in a pressurized aerosol dispenser, suitable for dispensing the aqueous polyol solution as a fine mist. The particle size of the description is controlled through the selection of valve dimensions and activator, as well as the formulation requirements. In one embodiment, the composition for treating the air according to the present disclosure may include water, a low molecular weight polyol (PM), an emulsifier, and a propellant, as follows: I ngredient Percentage by weight Water (de-ionized ) 20-90% Low PM polyol 5-25% Emulsifier 0-4% Propellant 10-50% It is also possible to include a cosolvent, such as alcohol, in the aerosol composition to facilitate the solubilization of the ingredients. Preferably, the cosolvent is a low molecular weight C1-4 monohydric alcohol, such as ethanol, propanol, isopropanol, butanol or isobutanol. Other joint solvents such as acetone may also be included in the aerosol composition. In a general embodiment, an emulsifier may be present as set forth below. If the cosolvent is present in an insufficient amount to form an emulsion without the presence of the emulsifier, the emulsifier may be present in said case in an amount ranging from about 0.4 to about 4% by weight. Additional adjuvants may also be included, such as fragrances, corrosion inhibitors, pH adjusters, antimicrobials, preservatives and the like. The preferred individual ranges for the aforementioned adjuvants are from 0 to 5% by weight, more preferably from 0 to approximately 2% by weight. A preferred pH of the composition is within the range of about 8 to about 1 0. The composition for treating the aforementioned air can be used in combination with valve and activator dimensions, and with spray performance parameters, as follows: Dimension / Property Interval Inner diameter of immersion tube 0.1 01 6-0.30988 (0.040"-0.1 22") Steam wrench diameter 0.00762-0.0508 (0.003"-0.020") Body hole diameter 0.02032-0.1 5748 (0.008"-0.062") Stem hole 0.03556-0.0762 (0.01 4"-0.030") Particle size ( Initial) = 45 microns Particle size (200 g) = 45 microns Spray rate 0.5-2.5 g / sec Retention < 5% Valve and activator dimensions and spraying performance parameters can also be found in relation to the aforementioned. With regard to particle size, a preferred particle size is within the range of about 25 to about 40 μ? , and more preferably within the range of about 30 to about 38 μ? . The processor of the present disclosure provides the desired small particle size and consistency during the use of the package. The retention ratio obtained is also preferred. The procedures for determining particle size, spraying ratio and retention are described below. The present disclosure provides an aerosol dispenser assembly which preferably supplies substantially all of an aqueous composition to treat the air (is to say, it provides a low product retention) as a spray having a desirable particle size and supply ratio, while at the same time employing an optimum amount of propellant to dispense the aqueous product from the interior of the package. In one aspect, an aerosol dispenser assembly of the present disclosure includes a container containing an aqueous product for treating the air and a propellant for propelling the product from the interior of the container. The propellant is preferably a hydrocarbon propellant and may be present in an amount ranging from about 10 to about 50% by weight. Preferably, the propellant is present in an amount of 45% by weight or less, even more preferably 40% by weight or less, and ideally about 35% by weight or less. The contents of the package are pressurized to form approximately (55 psig, 3.743 atm) at approximately (1 20 psig, 8.166 atm). In particular, the contents of the package are pressurized to form approximately (55 psig, 3.743 atm) at approximately (80 psig, 5.444 atm). A valve is attached to the container to selectively dispense the liquid product from the container as a mist, where said mist has an average particle size less than or equal to 45 μ? (0.0018"), for at least the first 75% of the life of the dispenser assembly Average particle size, as used herein, means average mass particle size (also known as volumetric mean) D (V.0.5) of the product dispensed, measured by a Malvern® Mastersizer 2600 Particle Size Analyzer, and as described in Basic Principles of Particle S / 'ze Analysis, by A. Rawle, Malvern Instruments Limited. In addition, the dispenser assembly is preferably capable of dispensing more than 95% by weight of the aqueous polyol solution from the package, ie, having less than 5% by weight of product retention, more preferably 98% by weight of the product. Aqueous product to treat the air coming from the container, that is to say, that presents a retention of product less than 2% by weight.

A vapor inlet is formed inside the valve to facilitate uniform mixing of the propellant and liquid product before dispensing, and a valve stem is placed inside the valve. The valve stem defines at least one stem orifice for the flow of the combined product (ie the vapor from the steam inlet and the liquid from the dip tube) during the supply. The steam intake has a diameter of about 0.076 mm (0.003") to about 0.508 mm (0.020"), more preferably about 0.330 mm (0.01 3") to about 0.483 mm (0.01 9") to dispense within the range of propellant of ~ 20 to -25% by weight, and a range of approximately 0.076 mm (0.003") to approximately 0.330 mm (0.01 3") to dispense between -1.5 to -20% by weight of propellant. A dispenser cap is mounted to the valve stem to activate the valve in order to dispense the liquid product. The Dispenser cap defines an exit route through which the liquid product can be dispensed. A stirring / mixing component can be placed within the outlet path of the dispenser lid to break or mix the liquid product in order to reduce the size of the particles before dispensing the liquid product. The stirring / mixing component can be a rotating chamber, a break bar and variations thereof, or other suitable components. The valve may also have the specifications described in U.S. Patent Nos. 6,824,079 and 7,014,127, which are commonly assigned with the present application and are incorporated herein by reference.

In one embodiment, the aerosol composition contains about 30% by weight of the propellant. As shown in Examples C1-C4 and C7-C1 1 below, it is possible to adapt a wide range of propellant concentrations within the scope of the present disclosure. In addition, the inclusion of the propellant at any other suitable concentration will be apparent to a person with ordinary skill in the art. Cosolvent A cosolvent can optionally be included in the composition aerosol to aid in the solubilization of the included ingredients, or to assist in the formation of a desired emulsion. Preferably, the cosolvent is a low molecular weight monohydric alcohol, such as a C 1 -C 4 alcohol, including ethanol, propanol, isopropanol, butanol, isobutanol. Additionally, the co-solvent may also include another organic solvent of low molecular weight, such as acetone. In one embodiment, the cosolvent is ethanol. In another embodiment, the cosolvent is isopropanol. Since a cosolvent can contribute to the total VOC content of the composition, the presence of a cosolvent in the aerosol composition is optional, and preferably in an amount not greater than about 40% by weight and preferably at a concentration lower than the content of the composition. Water. In a preferred embodiment, there is no presence of a solvent, and for this reason the presence of an emulsifier in an amount of about 0.4 to about 4% by weight is required to ensure the formation of the desired emulsion. On the other hand, the emulsifier content can be reduced if a cosolvent is used. In one embodiment, the composition for treating the air does not include any emulsifier. Fragrance Fragrances usually consist of a mixture of a number of fragrant materials, each of which has a particular fragrant sense. The number of fragrant materials in a fragrance is typically ten or more. The range of materials Fragrant used may vary. The materials come from a variety of chemical classes, but in general they are water soluble oils. In many cases, the molecular weight of a fragrance material is above 1 50, but does not exceed 300. The fragrance optionally included in the composition for treating the air described may be present in an amount that is sufficient to supply a pleasant aroma that can be perceived by a consumer in the presence of a bad odor, the fragrance can be present in an amount that covers at least a substantial part of the bad smell in the air. More preferably, the fragrance is preferably present in an amount that not only completely covers the bad air odors, but also provides a pleasant smell to be perceived by a consumer. In one embodiment, the fragrance is present in an amount ranging from about 0.01 to about 1% by weight, more preferably from about 0.01 to about 0.5% by weight, and ideally from about 0.01 to about 0.3% by weight.

Essential oils and extracts include, but are not limited to those derived from the following plants: almond, amyris, anis, armoise, bergamot, cabreuva, calendula, cannabis, cedar, chamomile, coconut, eucalyptus, fennel, jasmine, juniper, lavender, lemon, orange, palm, mint, quasia, rosemary, thyme, etc. Corrosion Inhibitor The use of water-based aerosol compositions makes it possible to manufacture products with lower flammability and lower ingredient costs. However, the use of water in said aerosol compositions further increases the problem of corrosion in the interior of tin-coated steel cans, which are so widely used., leading to the contamination of the aerosol product and finally leaks in the can if the corrosion is sufficiently serious. For this reason, corrosion inhibitors are preferably included in water-based aerosol compositions. If a can susceptible to corrosion is used with a composition containing water, one or more corrosion inhibitors may be included, such as potassium phosphates, potassium nitrite, sodium phosphates, sodium nitrite, mixtures of them, one or more other corrosion inhibiting agents. Dipotassium phosphate (K2HP04) is useful both as a corrosion inhibitor and as a pH regulator. Dipotassium phosphate can be used on its own or in combination with monopotassium phosphate (KH2P04). Disodium phosphate (Na2H P04) is also useful as a corrosion inhibitor and as a pH regulator, and can be substituted with dipotassium phosphate. Monosodium phosphate (NaH2P04) can also be used instead of or in addition to monopotassium phosphate. It has been found that the combination of dipotassium alone or of dipotassium and monopotassium and / or sodium phosphates is improved by the presence of another corrosion inhibitor in the form of potassium nitrite (KN02) and / or sodium nitrite (NaN02) . Accordingly, the presence of dipotassium phosphate or disodium phosphate can vary from about 0.01 to about 1.0% by weight, more preferably from about 0.02 to about 0.25% by weight. A suitable pH range for these salts is from about 6 to about 1 2, more preferably from about 7 to about 1 1, and even more preferably from about 8 to about 1 0. The amount of dipotassium phosphate or disodium phosphate can reduced if a small amount of monopotassium phosphate and / or monosodium phosphate is used as already mentioned in Examples 2 and 4, but the use of bisphosphate alone or monophosphates alone, is possible. If used, monopotassium phosphate and / or monosodium phosphate require to be present only in small amounts, but their presence may vary from about 0.01 to about 1.0% by weight, more preferably about 0.02% by weight. If used, the potassium nitrite may be present in an amount ranging from about 0.01 to about 1.0% by weight, more preferably from about 0.07 to about 0.1 5% by weight. The inhibitor can also be formed in situ with potassium hydroxide and phosphoric acid, or with sodium hydroxide and phosphoric acid. Monopotassium / monosodium phosphates may be added in amounts exceeding that of dipotassium / disodium phosphates to create pH regulating systems ranging from acid pH to alkaline pH, from about 5 to about 10, preferably from about 7 to about 9. In addition, the ammonium phosphate and / or ammonium nitrite can be used or combined with the aforementioned corrosion inhibitors. However, ammonium nitrite is explosive, and therefore, presents handling problems. The tripotassium and trisodium phosphates may also be used and neutralized to an acceptable pH with an acid such as phosphoric acid. Triethanolamine with sodium benzoate or with one or more of the other aforementioned inhibitors is a less preferred alternative for corrosion inhibition. As another alternative, the inhibition of corrosion can be imparted by borax (Na2B407-H20), alone or in combination with sodium nitrite or with one or more other inhibitors mentioned above. In one embodiment, the corrosion inhibitor includes potassium monophosphate and sodium bisphosphate. In a preferred embodiment, the corrosion inhibitor includes a 50/50 mixture of potassium monophosphate and sodium bisphosphate. Other suitable corrosion inhibitors that may be included in the composition will be apparent to those of ordinary skill in the art. PH Adjusting Agent Suitable agents for pH adjustment include conventional acids and salts, and salts thereof, such as ammonia, alkali metal hydroxides, silicates, borates, carbonates, bicarbonates, citrates, citric acid or mixtures thereof. In one embodiment, the agent for adjusting the pH is sodium hydroxide or potassium hydroxide. In another embodiment, the agent for adjusting the pH is ammonium hydroxide. The pH of the composition should fall within the range of about 6 to about 1 2, more preferably within the range of about 7 to about 11, and ideally from about 8 to about 1 0. The amount of agent to adjust the pH included in the composition to treat the air, to obtain the desired pH, would be apparent to who have ordinary knowledge in the matter. Preferably, the amount of pH modifying agent can be present in an amount ranging from about 0. to about 5% by weight, more preferably from about 0 to about 2% by weight. As shown in Figure 2, an aerosol dispenser assembly according to the present disclosure generally includes a package (2) with a valve assembly (4) disposed within the upper part thereof, for selectively dispensing a liquid product coming from the container (2). Referring to Figure 1, the valve assembly (4) further includes a mounting container (6), a mounting gasket (8), a valve body (10), a valve stem (12), a gasket of stem (14), an activator cover (16) and a return spring (18). The activator cover (16) defines an exit route (28) and an activator orifice (32). The valve stem (12), the rod seal (14), and the return spring (18) are positioned within the valve body (10) and are movable relative to the valve body (10). The valve body (10) is fixed to the underside of the mounting container (6), so that the valve stem (12) extends through it, and projects outwardly from the mounting container (6) . The trigger cover (16) fits on the projecting part of the valve stem (12), and a dip tube (20) is attached to the lower part of the valve body (10). The entire valve assembly (4) is sealed to a container (2) by means of the mounting gasket (8). Although the activator cap (16), as shown in Figure 1, is a simple push button actuator, it will be understood that any suitable activator can be used, such as, for example, an activator button with an integral top cover. In operation, when the activator cover (1 6) of the dispenser (1) is pressed, it forces the valve stem (12) to move down, opening the seal between the stem seal and the stem orifices, forming thus a flow route from the content to the external environment. The impeller propels the liquid product upwards from the immersion tube (20) and into the interior of the valve body (10) through the body orifice (22). Within the valve body (10), the liquid product can be mixed with additional propellant supplied to the valve body (10) through a steam outlet (24). The steam intake (24) helps to mix the liquid product and the propellant inside the valve body (10), in order to break the product into smaller particles to dispense. From the valve body (10), the liquid product is driven through at least one rod hole (26), out of the valve stem (12), and through an outlet path (28) formed within activator cover (1 6). As shown in Figure 1, it is possible to use a pair of shank holes (26). However, only one shank hole is required. A stirring / mixing component can be provided in the exit route to further mix or stir the product. The stirring / mixing component can be any suitable component, such as a rotating chamber, a breaker bar and variations thereof, or other suitable components, but not limited to these. The product is then expelled from the activator cap (16) through an activator orifice (32), which disperses the product and produces a desired spray pattern. In a variation of the dispenser assembly, instead of a break bar as shown in Figure 1, the dispenser assembly could employ a pair of break plates placed inside or below the exit route (28). It is known that many valve components affect the supply ratio of liquid product to propellant, including the steam intake, the stem orifice, the body orifice and the inner diameter of the immersion tube. In general, reducing the size of the steam intake has the effect of creating a thinner mixture (with a lower ratio of propellant to liquid), reducing the amount of retention, but increasing the particle size and spray ratio of the product supplied. On the other hand, reducing the size of the inner diameter of the stem orifice, body orifice and / or dip tube generally reduces both the dew rate and the particle size, and potentially increases the amount of product retention. Based on previous experimentation and analysis, and as will be discussed below, certain combinations of propellant type, can pressure and valve orifice dimensions can produce a dispenser assembly that is capable of distributing a high quality spray of spray. in the air, thus improving the performance of the composition to treat the air.

Addition- ally, the aerosol product dispenser assembly of Figures 1-2 is able to satisfactorily dispense a two-phase emulsion with overhead oil containing from about 10 to about 50% by weight of a propellant, and from about 5 to about 25% by weight of a water soluble polyol with odor elimination activity, when the diameter of the steam outlet (approximately) is between approximately 0.076 mm (0.003") and Approximately 0.508 mm (0.020"). More preferably, the diameter of the steam inlet (24) ranges from about 0.330 mm (0.01 3") to about 0.483 mm (0.01 9") when the contents of the propellant are within the range of -20 to ~ 35%. by weight and the diameter of the steam intake (24) varies from approximately 0.076 mm (0.003") to approximately 0.330 mm (0.01 3") when the content of the propellant is within the range of ~ 1 5 to ~ 20% by weight. The diameter of the shank hole (26) ranges from approximately 0.508 mm (0.020") to approximately 0.762 mm (0.030") when using a single shank hole (between 0.356 mm (0.01 4") and approximately 0.635 mm (0.025") )) when a pair of shank holes is used). The diameter of the body orifice (22) ranges from about 0.203 mm (0.008") to about 1.575 mm (0.062"), more preferably from about 1 .270 mm (0.050") to about 1.575 mm (approx. 0.062") when the contents of the propeller are within the range of -20 to -25%. The diameter of the body orifice (22) ranges from about 0.203 mm (0.008") to about 1 .270 mm (0.050") when the propellant content is in the range between ~ 1.5 and 20% by weight, and when the inner diameter of the dip tube (20) is between approximately 0.01 6 mm (0.040") and approximately 1.524 mm (0.060"). For this reason, any of the valve components, propeller types, propeller pressures and valve orifice dimensions can be used in combination to provide a dispenser assembly in accordance with the present disclosure. In one embodiment of the present disclosure, the aerosol dispenser assembly (1) utilizes a series A propeller having a propeller pressure of approximately 4,083 atm (57 psig) (ie, propellant A-57) to dispense the liquid product from the container (2). In the present embodiment, the container is initially pressurized at a can pressure of about 4,763 atm (70 psig) to about 5,444 atm (80 psig). The diameter of the steam inlet (24) in the present embodiment is approximately 0.406 mm (0.016"). Two shank holes (26) can be used, each having a diameter of approximately 0.610 mm (0.024"). . The diameter of the body orifice is approximately 1 .270 mm (0.050"), and the inner diameter of the dip tube is approximately 1.524 mm (0.060"). Another mode of the dispenser assembly (1) employs a single shank hole (26). In this embodiment, the dispenser assembly (1) further utilizes the A-57 propellant and a can pressure of about 4,763 atm (70 psig) to about 5,444 atm (80 psig) to dispense the liquid product from the interior of the container ( 2). The diameter of the steam inlet is approximately 0.406 mm (0.01 6"), the diameter of the single stem hole is approximately 0.635 mm (0.025"), the diameter of the body hole is approximately 1.575 mm (0.062) "), and the inner diameter of the immersion tube is approximately 1.524 mm (0.060"). These embodiments of the dispenser assembly are capable of dispensing the liquid product from the container as a mist, where said mist has an average particle size less than or equal to 45 μp? (0.0018"), for at least the first 75% of the life of the dispenser assembly, since the mist dispensed has such a small particle size, the particles are dispersed more easily in the air and less drop is experienced with these than with larger particle sizes, producing assemblies containing limited amounts of propellant of about 10 to about 50% by weight. This reduction in the amount of drop increases the efficiency of the dispenser assembly to eliminate odors and helps prevent undesirable residues of the liquid product from sitting on flat surfaces such as bars, tables or floors. Additionally, the spray ratio is preferably within a range of about 0.5 g / s to about 2.5 g / s for at least 75% of the life of the dispenser assembly. Although the preferred particle size and dew rate is described above, and thereafter in test examples, the particle size and dew rate may vary from dispenser to dispenser and due to various conditional variations, such as, but not limited to temperature, humidity and / or similar. The dew rate of 200 g / s and the particle size of 200 D (V, 0.5) are measurements of late-life product performance, preferably taken at approximately 50-75% of the product life. Since the dew point and particle size measurements consume product to be determined, the process of taking two dew point measurements and two particle size measurements results in a reduction in product weight that depends on the dew rate. Therefore, the weight value of the product remains constant at approximately 45% of the initial weight of the product. This initial weight choice of the product before taking the late stage measurements of the life of the product allows the measurement to be taken appropriately for a filling weight of 260 grams in a pack of 80 grams for spray ratios up to 2.5 g / s, without exhausting the dispensable product in the process. In addition, these preferred embodiments of the dispenser assembly are capable of dispensing more than 95% by weight of the liquid product from the container, i.e. leaving less than 5% by weight of product retention, and more preferably 98% by weight. by weight of the liquid product from the container, that is, leaving a retention of less than 2% by weight. In one embodiment, substantially all of the product can be dispensed into the air. In addition, by minimizing the amount of product held within the package at the end of the life of the dispenser assembly, less liquid product is wasted. This is important from the point of view of user satisfaction, since customers tend to be more satisfied with a dispenser assembly when substantially all the product has been dispensed. Additional modalities of composition, valve, activator top cap and spray performance parameters are described in the following examples. It is intended that the examples be illustrative, and not limiting.

The formation of an emulsion with oil above is critical to maintain good dew performance. All examples C1-C4 and comparative example C7 have a pH value of about 8.5 to about 9.5 for the liquid carrier, including the aqueous parts and the optional alcohol part. Comparative example C7 is a single-phase system. Agitation is not required, there is no presence of a two-phase emulsion. All examples C1-C4 and C7-C11 have a propellant level of no greater than about 50% by weight. However, higher values of propellant, such as 55% by weight, 60% by weight, 65% by weight, 70% by weight, 75% by weight or even 80% by weight may also be adequate and are considered within the scope of the present description. The incorporation of the propellant at various other concentrations will be apparent to those skilled in the art. The ethanol content in Examples C1, C2, C3 and C4 has a maximum level of 38.4% by weight. In comparative example C7, the contents of the composition dissolve with each other and form a single-phase product. Without adhering to any particular theory, the presence of solvent (ethanol) can contribute to the formation of the single-phase liquid. However, ethanol increases the total VOC content and, depending on the amount of ethanol present, can result in a composition having a high VOC content, as shown, for example, composition C7, which contains ethanol and not Water. In order to reduce the total VOC content of the composition, a part of the entire ethanol content of the composition can be replaced with water, as shown for example by the compositions C1-C4 and C8-C1.1. Since water is not classified as VOC, the total VOC content of the product is reduced when water is present. In some examples (not shown) the ethanol content is sufficient to completely dissolve the added water. In Examples C3 and 04, however, the water content is comparable with the ethanol content, and therefore, a two-phase system is formed. The hydroalcoholic mixture forms a two-phase emulsion of oil above when agitated, and the stability of the emulsion formed in this way can be improved by the presence of the emulsifier (in example 03). Example C8-C1 1 shows the inclusion of a propellant in an amount of about 30% by weight or greater. However, compared to the comparative example 07 mentioned above, the total VOC contents of the compositions C8-C1 1 are significantly reduce by reducing the content of the cosolvent. Preferably, the aerosol composition can have a total VOC content of not more than 60% by weight.

The V7 valve for the C7 composition is also available in Su mmit Packaging Systems (with body hole = 1.575 mm (0.062"), stem hole = 1..0.035 mm (0.025"), ID dip tube = 1.524 mm (0.060"), and steam outlet = 0.508 mm (0.020") In one embodiment, the aerosol dispenser assembly may include a container containing a composition for removing odors to treat the air, and a valve attached to the container for selectively dispensing the composition, wherein the dispensed composition has a particle size of mass less than or equal to 45 μp? for at least 75% of a dispenser assembly life and a dew rate within from a range of about 0.5 g / s to about 2.5 g / s for at least 75% of the life of said dispenser assembly, and where the valve includes a steam inlet with a diameter in the range of approximately 0.0762. mm (0.003") to approximately 2.08 mm (0.20"), and a valve stem defining at least one stem orifice, a sum of diameters of at least one rod hole of at least 0.254 mm (0.01 0"). The composition for treating the oil may provide one or more of the following advantages: (1) elimination of odors; (2) fine mist; (3) adequate spray rate; (4) low retention; (5) lack of corrosion in the can; (6) low manufacturing cost; (7) absence of toxicity or other harmful effects.

The above examples were tested using predetermined test procedures. The following is a summary of the conditions and parameters of the test procedures used to measure conditions and results, including dew rate, particle size and retention. Spray performance was evaluated under indoor environmental conditions, that is, at 21.1 ° C (70 ° F) and ordinary humidity. Samples were stored under indoor environmental conditions for at least 24 hours before testing. The dew rates were determined through the change in weight during a spray of 10 seconds, were reported as grams per second, and an average was obtained during two sprays during the first 40 seconds of the sample life. The activator is pressed completely during the measurement. The can is shaken properly before spraying, allowing up to 2-4 seconds between agitation and dew. The dew rate (200) was collected after spraying the sample to 200 g (formula + packaging) and averaged over two measurements. The particle size is the average mass diameter, D (V, 0.5), (μGt?) reported using a particle size analyzer by Malvern® laser diffraction equipped with a 300 mm lens. Aerosols were sprayed with the spray tip 45.72 cm (1 8") from the borehole, a cut was applied at 301.7 μm to eliminate phantom peaks caused by the" beam direction ". Dew for measurements of particle size were found between 5 and 10 seconds, depending on the darkening of the spray. The results were averaged over two measurements, collected during the first 40 seconds of the life of the sample. The samples were shaken adequately before taking the measurements allowing up to 2-4 seconds between agitation and dew. The particle size 200 D (V, 0.5) was further determined using a Malvern® analyzer, and was taken in samples that were sprayed to 200 grams (formula + packaging) and averaged at least two measurements. The aerosols were sprayed with the spray tip 45.72 cm (1 8") from the borehole., the measurements of the particle size (200) and the dew rate (200) alternated until completing two of each. Spraying was achieved by spraying cans for 1 0 second intervals once per hour, usually for a maximum of 6 sprays per day. This process tended to exhaust the pressure of the can, which was replenished by letting it rest for more or less 24 hours, depending on the quantity expelled as dew. Other critical measurements, such as particle size and spraying ratio, were not made before 24 hours of substantial spray expulsion (3 or more 10-second sprays). Product retention is the weight of material that remains inside the aerosol after completing the discharge of the propellant through the spraying process. The weight of the product retained was determined by obtaining the difference of the final weight of the package completely discharged (when the internal pressure is equal to the ambient pressure) minus the weight of the package following the opening of the container and cleaning the remaining contents with acetone (and drying). Product retention can be reported as retained grams or retention percentage. Although only certain modalities have been exposed, the alternatives and modifications will be evident from the previous description for experts in the field. These and other alternatives are considered equivalent and within the spirit and scope of the present disclosure, and the appended claims.
