Description

[Technical field]

[0001] The present invention relates to a spray nozzle for dispensing a structured composition, a spray article including the spray nozzle, and a method of spraying a structured composition with the spray nozzle. [Background technology]

[0002] Spray products with triggers are known. Trigger sprayers typically utilize a hand-held container that extends downward from a manual pump or pressurized container. The container can hold any composition that is desired to be sprayed in a stream, fine droplets, foam, or mist. The composition may include air fresheners, fabric fresheners, hairsprays, cleansers, etc.

[0003] The spray characteristics, such as droplet size, spray pattern, and flow rate, are determined by several parameters and operating characteristics of the pump, including nozzle geometry. Furthermore, the rheology of the composition being sprayed also affects the spray characteristics. Specifically, a composition that has a yield stress may be sprayed differently than an aqueous composition that does not have a yield stress. Summary of the Invention [Problem to be solved by the invention]

[0004] A need exists for a spray nozzle design that optimizes spray characteristics for spraying compositions having a yield stress. [Means for solving the problem]

The outlet orifice is defined by an outlet orifice diameter and an outlet orifice axial length, and the ratio of the outlet orifice diameter to the axial length is about 1.3 to about 3.5.

[0006] In another example, a spray product includes a composition contained within a reservoir, the composition including a plurality of particles and a structurant system, the structurant system including xanthan gum and a polysaccharide selected from the group consisting of konjac gum, locust bean gum, tara gum, and combinations thereof, the composition including a plurality of particles, the spray product further includes a valve in composition communication with the reservoir, an actuator in mechanical communication with the valve, a nozzle having an exit orifice, a swirl chamber in composition communication with the exit orifice, and a swirl chamber inlet channel of the plurality of swirl chambers in composition communication with the swirl chamber, the exit orifice being defined by an exit orifice diameter and an exit orifice axial length, the ratio of the exit orifice diameter to the axial length being about 1.3 to about 3.5.

[0007] Additionally, a method of freshening air includes providing a sprayer and spraying a composition from the sprayer, the composition including a plurality of particles and a structurant system, the structurant system including xanthan gum and a polysaccharide selected from the group consisting of konjac gum, locust bean gum, tara gum, and combinations thereof, the composition including a plurality of particles, and the sprayer further includes a valve in composition communication with a reservoir, an actuator in mechanical communication with the valve, a nozzle having an outlet orifice, a swirl chamber in composition communication with the outlet orifice, and a swirl chamber inlet channel of the plurality of swirl chambers in composition communication with the swirl chamber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Although the following description describes a spray product including a spray actuator, a composition, a housing, a trigger, a nozzle, and a container, each having various components, it should be understood that the spray product is not limited to the configurations and arrangements set forth in the following description or illustrated in the drawings. The spray product including the actuator, housing, trigger, nozzle, pump assembly, container, and composition of the present disclosure may be applicable to other configurations or may be implemented or performed in various ways. For example, the components of the trigger, valve, nozzle with exit orifice, and swirl chamber may be used with various pump assemblies for manually operated trigger sprayers or valve stems of aerosol type sprayers. Furthermore, the trigger and / or pump assembly may be used with various spray actuators to deliver the composition into the air.

[0010] The present disclosure relates to a spray product comprising a spray actuator, a container, and a composition contained in the container. The sprayer of the present disclosure may include an actuator optimized to spray a composition having a viscosity in the range of about 1 mPa-s to about 20 mPa-s as measured according to the Rheology Test Method disclosed herein. The composition may also have a yield stress of greater than 0 to about 1,000 mPa as measured according to the Rheology Test Method disclosed herein. The actuator is optimized to provide a broad spray pattern with small particles and high flow rates. The composition of the present disclosure may include a plurality of particles and a structurant system to suspend the particles.

[0011] 1-6 illustrate a non-limiting example of a spray product 20 of the present disclosure. As shown in FIG. 1, the spray product 20 includes a container 22 and an actuator 24. The actuator 24 includes a housing 26, a trigger 28, and a nozzle 30. The spray product 20 can be a non-aerosol manually actuated trigger sprayer, or any other suitable type of sprayer that can benefit from the features described herein. As previously mentioned, the actuator 24 or portions thereof can also be used in conjunction with aerosol type sprayers as well. The spray product 20 and the spray actuator 24 can have a longitudinal axis that is parallel to a portion of the composition flow rate during dispensing. With reference to FIG. 2 and FIG. 3, the nozzle 30 can be frictionally joined to the housing 26.

[0012] Referring to FIG. 1, the container 22 can be any suitable type of container for holding a product to be dispensed by the sprayer. The container 22 can be any suitable shape. The container 22 has a base 32, sides 34, a bottom 36, a top 38, and a top 40. The container 22 can be generally cylindrical, but the sides 34 of the container can taper inwardly with a slight convex curvature onto the top 38 of the container, thereby becoming narrower at the top 38. The base 32, bottom 36, or sides 34 can be larger (e.g., wider, more voluminous, etc.) than the top 38 and / or top 40. The container 22 can have numerous other shapes in different configurations. The container may include a variety of materials, including plastic, metal, glass, etc., and combinations thereof. A single spray actuator 24 can be utilized with containers 22 of various sizes and designs.

[0013] 1 and 2, the spray actuator 24 may include a dip tube 31 that extends from a lower portion 36 of the container 22 to the spray actuator 24. The dip tube 31 may be in composition communication with the composition contained within the container 22 at a first end and with the spray actuator 24 at an opposite second end. The composition contained within the container 22 may be drawn through the dip tube 31, or, if in aerosol form, may be forced through the dip tube 31, in response to actuation by a trigger 28.

[0014] The actuator housing 26 may be configured in a variety of different shapes and sizes. With reference to Figures 1 and 2, the actuator housing 26 may have a lower portion 42, an upper portion 44, a waist portion 46, and a top portion 48. The lower portion 42 may be attached to the container 22 and may fit on or over the container 22 as shown. The waist portion 46 may be located between the lower portion 42 and the upper portion 44. The waist portion 46 may be narrower than the widest portion of the upper portion 44 and / or the lower portion 42, respectively. The waist portion 46 and the lower portion 42 may each be narrower than the widest portion of the upper portion 44. The waist portion 46 provides an ergonomic design for the actuator 24.

[0015] Actuator housing 26 may be configured to allow a user to wrap at least the user's thumb and index finger around waist portion 46. In such a configuration, actuator housing 26 may also include a configuration that allows it to comfortably conform to the natural contours of the user's palm, such as the creases of the user's palm.

[0016] The sprayer nozzle 30 is oriented such that the composition sprayed from the nozzle 30 is directed at an angle greater than 0° and less than 90°, so that the top 48 of the actuator housing 26 may be tilted upward. That is, the composition does not have to be sprayed parallel to the base 32 (i.e., horizontally when the base is placed on a horizontal surface) or vertically (straight up in the axial direction of the container). The composition may be sprayed from the nozzle 30 at an angle greater than 0° and less than 90°.

[0017] It may be desirable for the composition sprayed from the nozzle 30 to be sprayed horizontally (0°) or vertically (90°). In still other situations, such as in the case of ironing aids, it may be desirable for the composition sprayed from the nozzle 30 to be directed downwards (at an angle of 0° to -90°) towards the surface. However, it is understood that the spray pattern is typically in the form of a dispersion, and the spray emitted from the nozzle forms an angle of the dispersed spray pattern when viewed from the side. The angle of spray referred to herein is a central axis that bisects such a spray pattern. It is understood that portions of the spray pattern are typically distributed on either side of this central axis. With reference to Figures 1 and 2, the actuator 24 may be removably attached to the container 22 in any manner known in the art for removably attaching an article to a container, including, but not limited to, threads, bayonet fittings, and snap fits. The actuator 24 may be permanently attached to the container 22, or the actuator 24 may be removably attached to the container 22. Additionally, the actuator housing 26 may include an opening 47 for the trigger 28 to extend therethrough.

[0018] 1-6, the spray actuator 24 may be configured as a manually actuated trigger spray actuator or as an aerosol-based trigger spray actuator. The manually actuated spray actuator 24 includes a pump assembly 53. Manual actuation of the trigger 28 through its stroke causes corresponding vertical movement of a piston 54 of the pump assembly 53. The vertical movement of the piston 54 pumps the composition from the container 22, through the flow passage, and out of the nozzle 30. The piston 54 may move in a reciprocating motion within a pump body 55. The spray product 20 may utilize an articulating top pivoting trigger 28.

[0019] In contrast, in an aerosol-based system, depression of a trigger opens a valve that allows dispensing of the composition under pressure. The composition can be pressurized by known propellants, which can be hydrocarbon-based, compressed air-based, or a combination thereof. Hydrocarbon and compressed air propellants are well known in the art.

[0020] In either a manually operated trigger sprayer or an aerosol sprayer, a return spring 56 biases the trigger 28 away from the container 22 and into a forward position ("forward motion") at the end of the stroke. The return spring 56 may be configured as two curved parallel springs 56. The return springs 56 may be connected at each end and positioned outside the piston 54 / composition chamber 58. A vertical upward flow path for the composition may be positioned between the return springs 56. In a manually operated trigger sprayer, squeezing the trigger 28 toward the container ("backward motion") creates hydraulic pressure in the composition chamber 58 and the composition is dispensed. The forward motion of the trigger 28 creates a vacuum, drawing in the composition from the container 22 to refill the composition chamber 58.

[0021] 3, once the composition chamber 58 is primed, rearward movement of the trigger 28 is translated into downward movement of the piston 54 within the pump body 55. The downward movement of the piston 54 pressurizes the composition chamber 58. When the pressure in the composition chamber 58 reaches a predetermined level, resistance forces within the system are restored, causing the valve 60 to open and the composition to flow from the nozzle 30 through the conduit 62. The return spring 56 automatically and repeatedly moves the trigger 28 to its forward rest position and the composition chamber 58 is refilled with the composition.

[0022] 4, and considering pump assembly 53 in more detail, pump body 55 may have a stepped configuration and may house a reciprocating piston 54. Pump body 55 may be captured by a threaded closure 50 on lower portion 52 of actuator 24. Threaded closure 50 may be opened, if desired, to access and replenish the composition within container 22. Although threaded closure 50 is shown in FIG. 4, it should be understood that the closure may be configured as a different type of closure, such as a bayonet or snap-fit.

[0023] 2-4, the reciprocating piston 54 may have an upper sealing portion 150U and a lower sealing portion 150L, ​​both of which fit within the body 48. The valve 60 disposed within the piston 54 may have its vertical movement resisted by a spring (not shown). When the force from the actuation of the trigger 28 increases the force applied to the piston 54, the valve 55 may move downward, pressurizing the composition within the chamber 44 for later dispensing. The conduit 62 may be configured in a variety of ways. For example, referring to FIG. 2, the conduit 62 may be flexible and bent at approximately 90 degrees. The flexible conduit 62 bends at a bend 64, with a slightly increasing angle at bend 65, in response to the actuation of the trigger 28 / crank rocker. The downstream portion of the conduit 62 bends at the bend 64 and terminates at a post 66. The post 66 is inserted into the nozzle 30 up to a shoulder of the post 66. The post may have two longitudinally opposed ends, an upward flow end into which the bent conduit 62 described above is fitted, and a downward flow end which fits into the nozzle 30 .

[0024] 2 and 7-9, the composition flows around the post 66 and into a number of swirl chamber inlet channels 80. The composition flows from the conduit 62 through the swirl chamber inlet channels 80, which direct the composition into the swirl chambers 82. The swirl chamber inlet channels 80 and swirl chambers 82 impart a tangential rotation to the composition before it reaches the nozzle exit orifice 84 of the nozzle 30. The swirl chamber inlet channels, swirl chamber, and nozzle 30 are stationary. The inlet channels are angled such that the composition enters the swirl chamber at an acute angle relative to the radius of the swirl chamber.

[0025] 2 and 7-8, the swirl chamber inlet channel 80 is defined by the juxtaposition of the outer surface of the post 66 and the inner surface of the nozzle 30. The swirl chamber inlet channel 80 may be disposed on the post 66, or the swirl chamber inlet channel 80 may be disposed within the nozzle 30. If the swirl chamber inlet channel 80 is disposed on the post 66, the post 66 may have two or more longitudinally oriented slots equally spaced circumferentially around its downstream portion. The post 66 may have a length of about 11 mm and a stepped diameter of about 4-5 mm. The atomizer may include 2, 3, 4, 5, 6, 7, or 8 swirl chamber inlet channels.

[0026] The swirl chamber 82 may be located at the end of the post 66, or the swirl chamber 82 may be located on an inner surface of the nozzle 30. Figures 2 and 3 illustrate a non-limiting actuator having a swirl chamber 82 and swirl chamber inlet channel 80 located on the post 66. Figures 7 and 8 illustrate a non-limiting nozzle having a swirl chamber 82 and swirl chamber inlet channel 80 located on the nozzle.

[0027] 2, 3, and 7-9, upon exiting the swirl chamber 82, the composition passes through a nozzle exit orifice 84 of the nozzle 30 for distribution into the atmosphere or onto a target surface. The nozzle exit orifice 84 has an exit orifice diameter D, which is the inner diameter of the exit orifice. O and the axial length of the outlet orifice is the outlet orifice axial length d l The nozzle exit orifice 84 may be defined by an exit orifice diameter D O and may be radiused on the outer surface. The outlet orifice may have an outlet orifice axial length d l The outlet orifice diameter D O and the outlet orifice axial length d lThe ratio of may be in the range of about 1.3 to about 3.5, or more preferably, about 1.5 to about 3.2, specifically reciting all values ​​within these ranges and any ranges created thereby. The composition is dispensed from nozzle 30 in a predetermined spray pattern, which may vary according to the stroke speed, stroke length, etc., of actuation of trigger 28. Provision may be made to adjust the spray pattern, if desired.

[0028] 7 to 9, the swirl chamber 82 has a swirl chamber diameter D s The swirl chamber diameter D s is the lateral inner diameter of the recess forming the swirl chamber 82. The swirl chamber inlet channel 80 has a tangential depth d t and tangential width d w The entire pump assembly 53 may be enclosed within the housing 70. Other than the nozzle 30, there may be no direct openings from the pump assembly 53 to the outside of the housing 70.

[0029] 5-6, trigger 28 may be configured to provide movement that is more perpendicular / radially oriented relative to the longitudinal axis than the configuration shown in FIGS. 2 and 3. This orientation of movement may be achieved by providing a mounted pivot 68 located near the top portion of trigger 28. A rearward facing protrusion 70 on trigger 28 may pivot upwardly relative to a rocker arm 72 of an articulatable crank rocker 74. Rocker arm 72 is mounted on two pivots 69. An opposite end 76 of crank rocker 74 articulates downwardly providing a force F aligned or coincident with the longitudinal axis. This force F moves piston 54 in a downward direction, pressurizing the composition in composition chamber 58. Referring back to FIG. 4, the composition in the lower portion of composition chamber 58 is displaced by piston 54 and flows upward through an annular portion of composition chamber 58, past valve 60, and into conduit 62.

[0030] In a manually actuated trigger sprayer, the pump assembly 53 may be configured as a pre-compression pump assembly as known to those skilled in the art.

The longest protruding dimension of any single particle within the plurality of particles is taken as the length of the longest linear dimension that can be entirely inscribed within the perimeter of the single particle. The average longest protruding dimension of the plurality of particles may be taken as the longest linear dimension that can be entirely inscribed within the single particle across all particles within the plurality of particles. It will be understood by those skilled in the art that this average may also be reflected by taking the average across a sample of statistically relevant particles from the plurality of particles.

[0050] With respect to unencapsulated fragrance, the composition may comprise from about 0.001% to about 2.0%, or from about 0.01% to about 1.0%, or most preferably from about 0.05% to about 0.5% by weight of the composition of unencapsulated fragrance.

[0051] Structuring Agent System The composition may include a structuring agent system having at least one structuring agent. The structuring agent may include one or more biopolymers. Non-limiting examples of such biopolymers include polysaccharides such as polymers of glucose, fructose, galactose, mannose, rhamnose, glucuronic acid, and mixtures thereof.

[0052] The structurant system may be in the form of a polysaccharide system. Preferred polysaccharides include xanthan gum, glucomannan, galactomannan, and combinations thereof. Glucomannan may be derived from natural gums such as konjac gum. Galactomannan may be derived from natural gums such as locust bean gum and / or tara gum. Polysaccharides may include carrageenan. Polysaccharides may be modified, such as by deacetylation.

[0053] The composition may include a polysaccharide system including at least two polysaccharides, such as a first polysaccharide and a second polysaccharide. The first polysaccharide may be xanthan gum. The second polysaccharide may be selected from the group consisting of glucomannan, galactomannan, and combinations thereof. The second polysaccharide may be selected from the group consisting of konjac gum, locust bean gum, tara gum, and combinations thereof.

[0054] Preferably, the first polysaccharide is xanthan gum and the second polysaccharide is konjac gum. The first polysaccharide may be present at a concentration of greater than 10% and less than 90% by weight of the polysaccharide system, alternatively from about 20% to about 80% by weight, alternatively from about 40% to about 60% by weight.

[0055] The second polysaccharide may be present at a concentration of from about 15% to about 85%, alternatively from about 20% to about 80%, alternatively from about 40% to about 60% by weight of the polysaccharide system.

[0056] The total concentration of polysaccharides present in the composition can be less than about 0.5% by weight, or preferably less than about 0.2% by weight, or preferably less than about 0.1% by weight, more preferably less than 0.08% by weight, and most preferably less than 0.06% by weight, specifically reciting all values ​​within these ranges and any ranges created thereby. Without wishing to be bound by theory, it is believed that minimizing the total concentration of polysaccharides present in the composition reduces residue and / or optimizes spray characteristics.

[0057] The polysaccharide may have a weight average molecular weight within the range of about 10,000 daltons to about 15,000,000 daltons, preferably about 200,000 daltons to about 10,000,000 daltons, more preferably about 500,000 daltons to about 9,000,000 daltons, more preferably about 750,000 daltons to about 8,000,000 daltons, more preferably about 1,000,000 daltons to about 7,000,000 daltons, more preferably about 2,000,000 daltons to about 6,000,000 daltons, more preferably about 3,500,000 daltons to about 6,000,000 daltons, and specifically, all values ​​within these ranges and any ranges created thereby are listed.

[0058] Polysaccharides may be characterized by their acetylation ratio. The acetylation ratio of one or more of the polysaccharides, such as xanthan gum, may be in the range of about 5.0 to about 0.2, preferably in the range of about 3.5 to about 0.3, preferably in the range of about 2.0 to about 0.35, preferably in the range of about 1.5 to about 0.37, preferably in the range of about 1.0 to about 0.39, specifically reciting all values ​​within these ranges and any ranges created thereby.

[0059] The composition may have a total protein concentration of less than about 100 parts per million (ppm), preferably less than 50 ppm, preferably less than 25 ppm, more preferably less than 10 ppm.It may be desirable to limit the total protein concentration in the composition to minimize discoloration of the surface to which the composition is applied.

[0060] Buffer The composition may include a buffering agent, which may be a carboxylic acid, or a dicarboxylic acid, such as maleic acid, or a polybasic acid, such as citric acid or polyacrylic acid. The acid may be sterically stable and may be used in the composition to maintain a desired pH. The buffering agent may include a base, such as triethanolamine, or an organic acid salt, such as sodium citrate. The composition may have a pH of about 3.0 to about 7.0, preferably about 4.0 to about 6.5, more preferably about 4.0 to about 6.0, specifically reciting all values ​​within these ranges and any ranges created thereby.

[0061] Solubilizer The composition may contain solubilizing aids to solubilize excess hydrophobic organic materials, particularly certain malodor counteractants, perfume materials, and optional ingredients that may be added to the composition but are not readily soluble in the composition (e.g., pest repellents, antioxidants, etc.), to form a clear, light-transmitting solution. Suitable solubilizing aids are surfactants, such as non-foaming or low-foaming surfactants. Suitable surfactants are nonionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants, and mixtures thereof.

[0062] The composition can contain nonionic surfactants, cationic surfactants, and mixtures thereof.The composition can contain ethoxylated hydrogenated castor oil.One type of suitable hydrogenated castor oil that can be used in the composition is sold under the name Basophor™, available from BASF.

[0063] Surface tension reducing agents The composition may include a wetting agent that provides a low surface tension that allows the composition to spread easily and more uniformly on hydrophobic surfaces such as polyester and nylon. It has been found that the composition does not spread well without the use of such a wetting agent. Spreading the composition also allows the composition to dry quickly, so that the treated material is ready for immediate use. Furthermore, compositions containing wetting agents can penetrate hydrophobic oily soils better for improved odor neutralization. Compositions containing wetting agents can also improve "in-wear" static control. In concentrated compositions, wetting agents facilitate the dispersion of many actives, such as antimicrobial actives and fragrances, in the concentrated composition.

[0064] Non-limiting examples of wetting agents include block copolymers of ethylene oxide and propylene oxide. Suitable block polyoxyethylene-polypropylene polymer surfactants include those based on ethylene glycol, propylene glycol, glycerol, trimethylolpropane, and ethylenediamine as the initial reactive hydrogen compound. 12~18 Polymeric compounds made by sequential ethoxylation and propoxylation with a single reactive hydrogen atom, such as fatty alcohols, are generally not compatible with cyclodextrins. Specific block polymer surfactant compounds include Pluronic® and Tetronic® manufactured by BASF-Wyandotte Corp., Wyandotte, Michigan.

[0065] Non-limiting examples of this type of wetting agent include the Silwet® surfactants described in U.S. Patent No. 5,714,137 and available from Momentive Performance Chemical, Albany, N.Y. Exemplary Silwet surfactants are as follows:

[0066] [Table 1] and mixtures thereof.

[0067] Odor neutralizer The compositions may include other malodor reducing technologies, including, but not limited to, amine functional polymers, metal ions, cyclodextrins, cyclodextrin derivatives, polyols, oxidizing agents, activated carbon, and combinations thereof.

[0068] fragrance delivery technology The composition may include one or more perfume delivery technologies that stabilize and enhance the attachment and release of perfume ingredients from the treated substrate.Such perfume delivery technologies can also be used to extend the release life of perfume from the treated substrate.Perfume delivery technologies, methods of making certain perfume delivery technologies, and methods of using such perfume delivery technologies are disclosed in US Patent Application Publication No. 2007 / 0275866(A1).

[0069] The composition may comprise about 0.001% to about 20% by weight, preferably about 0.01% to about 10% by weight, preferably about 0.05% to about 5% by weight, more preferably about 0.1% to about 0.5% by weight of the perfume delivery technology. In one embodiment, the perfume delivery technology may be selected from the group consisting of pro-perfume, polymer particles, soluble silicones, polymer-assisted delivery, molecule-assisted delivery, fiber-assisted delivery, amine-assisted delivery, cyclodextrins, starch encapsulated accords, zeolites, and inorganic carriers, and mixtures thereof.

[0070] The perfume delivery technology may include amine reaction products (ARPs) or thio reaction products. "Reactive" polymeric amines and / or polymeric thiols may be used, in which amine and / or thiol functional groups are pre-reacted with one or more PRMs to produce a reaction product. Typically, reactive amines are primary and / or secondary amines and may be part of a polymer or monomeric (non-polymeric). Such ARPs may also be mixed with additional PRMs to provide polymer-assisted and / or amine-assisted delivery benefits. Non-limiting examples of polymeric amines include polyalkylimines, such as polyethyleneimine (PEI), or polymers based on polyvinylamine (PVAm). Non-limiting examples of monomeric (non-polymeric) amines include hydroxylamines, such as 2-aminoethanol and its alkyl-substituted derivatives, and aromatic amines, such as anthranilates. ARPs may be premixed with perfume or added separately for leave-on or rinse-off applications. Materials containing heteroatoms other than nitrogen and / or sulfur (such as oxygen, phosphorus or selenium) may be used as alternatives to amine compounds. The above alternative compounds may be used in combination with amine compounds. A single molecule may contain an amine moiety and one or more of alternative heteroatom moieties (such as thiol, phosphine, and selenol). The effect may include improved perfume delivery as well as sustained release of perfume. Suitable ARPs and their manufacturing methods may be found in US Patent Application Publication No. 2005 / 0003980 (A1) and US Patent No. 6,413,920 (B1).

[0071] Unpackaged fragrance The composition may include a non-encapsulated fragrance, which includes one or more fragrance ingredients that only provide a hedonic effect (i.e., do not neutralize malodors but provide a pleasant aroma). Suitable fragrances are disclosed in U.S. Patent No. 6,248,135. For example, the composition may include a mixture of a volatile aldehyde for neutralizing malodors and a fragrance aldehyde that provides hedonic effects.

[0072] When a fragrance other than the volatile aldehyde in the malodor control component is blended into the composition, the total amount of unencapsulated fragrance and volatile aldehyde may be about 0.015% to about 3% by weight of the composition, preferably about 0.01% to about 1.0% by weight, and more preferably about 0.015% to about 0.5% by weight.

[0073] Water-Based Carrier The composition may include an aqueous carrier. The aqueous carrier used may be distilled water, deionized water, or tap water. Water may be present in any amount in the composition, which is an aqueous solution. Water may be present in an amount of about 85% to 99.5% by weight of the composition, preferably about 90% to about 99.5% by weight, more preferably about 92% to about 99.5% by weight, more preferably about 95% by weight. Water containing small amounts of low molecular weight monohydric alcohols, such as ethanol, methanol, and isopropanol, or polyols such as ethylene glycol and propylene glycol, may also be useful. However, volatile low molecular weight monohydric alcohols such as ethanol and / or isopropanol should be limited, as these volatile organic compounds contribute to both flammability and environmental pollution problems. When small amounts of low molecular weight monohydric alcohols are present in the composition because they have been added to the composition as flavorings and as stabilizers for some of the preservatives, the concentration of the monohydric alcohol may be from about 1% to about 5% by weight of the composition, alternatively less than about 6%, alternatively less than about 3%, or alternatively less than about 1%.

[0074] Adjuvants Adjuvants can be added to the compositions herein for known purposes, including, but not limited to, diluents, preservatives, antimicrobial actives, water-soluble metal salts, including zinc salts, copper salts, and mixtures thereof; antistatic agents; insect and moth repellents; colorants; antioxidants; aromatherapy agents, and mixtures thereof.

[0075] Sprayable Products The composition may be packaged in a spray dispenser to form a sprayable product. The sprayable product may be suitable for use in the air and on surfaces. The spray dispenser includes a nozzle of the present invention.

[0076] The sprayable product can be configured to deliver a fine mist of liquid. The spray dispenser can be configured in various ways, such as a direct compression trigger sprayer, a pre-compression trigger sprayer, or an aerosol spray dispenser. One suitable spray dispenser is the TS800 trigger sprayer (Exxon Mobil PP1063, material classification 10003913, manufacturer: Calmar).

[0077] Another suitable spray dispenser includes a continuous action sprayer such as the FLAIROSOL™ dispenser manufactured by Afa Dispensing Group, which includes a bag-in-bag or bag-in-can type container with a pre-compression spray engine and an aerosol-like compressor of the composition.

[0078] The sprayable product may include a spray engine and a container. The composition may be disposed in the container. The container containing the composition may be available separately from the spray engine, such as a refill container.

[0079] How to use The compositions of the present invention can be used by spraying, for example, by placing the aqueous solution in a dispensing means such as a spray dispenser and spraying an effective amount into the air or onto a desired surface or item. Effective amount, as defined herein, means an amount sufficient to purify the air or surface and / or neutralize malodors to an extent that is not detectable by human olfactory sense, but not so much that the item or surface is saturated with liquid or forms a puddle of liquid, and when dry, there is no easily recognizable visible deposit. Spraying can be achieved by using a spray device.

[0080] The present disclosure encompasses a method of applying an effective amount of the composition onto a household surface to reduce malodors and / or clean the household surface, the household surface being selected from the group consisting of countertops, cabinets, walls, floors, carpets or rugs, bathroom surfaces, trash and / or recycling bins, appliances, and kitchen surfaces.

[0085] The present disclosure relates to a method of applying a mist of an effective amount of a composition to pets in the home to cleanse and / or neutralize malodors.

[0086] Test Method Rheological Testing Methods To measure the yield stress and / or viscosity of the samples, measurements are performed using a TA Discovery HR-2 Hybrid Rheometer (TA Instruments, New Castle, Delaware, USA) and accompanying TRIOS software version 4.2.1.36612, or equivalent. The instrument is equipped with a concentric cylinder double gap cup (e.g., TA Instruments, cat.#546050.901), a double gap rotor (e.g., TA Instruments, cat.#546049.901) and a split cover (e.g., TA Instruments, cat.#545626.001). Calibration is performed according to the manufacturer's recommendations. A cooling circulating water bath set at 25° C. is attached to the concentric cylinder. The concentric cylinder temperature is set to 25° C. The temperature is monitored in the control panel until the instrument reaches the set temperature, at which point the sample material may be loaded into the Double Gap Cup after an additional 5 minutes to ensure equilibration.

[0087] The parameters for the Double Gap Cup are as follows: inner cup diameter is 30.2 mm, inner bob diameter is 32 mm, outer bob diameter is 35 mm, outer cup diameter is 37 mm, inner cylinder height is 55 mm, immersion height is 53 mm, operating gap is 2,000.0 μm, loading gap is 90,000.0 μm, environmental system is Peltier, and sample volume is 12 mL to 15 mL (preferably 12 mL). Cover the concentric cylinder Double Gap Cup with a solvent trap to prevent drying during testing (e.g., 545626.001, Split Cover for DHR&AR Series Smart Swap Peltier Concentric Cylinder).

[0088] To load a new sample, the Double Gap Cup is washed, dried and reassembled according to the manufacturer's instructions. A minimum of 12 ml of sample is added to the Double Gap Cup using a syringe, and the sample is then allowed to sit for 15 minutes to ensure that any trapped air bubbles rise to the surface. The Double Gap Rotor is then lowered to the appropriate gap and data is collected according to the setup and procedure in the following sequence of steps:

[0089] Load new sample. The first sample conditioning step is performed using the following instrument settings: Environmental Control set at Temperature of 25° C.; Inherit Set Point selected as Off; Soak Time set to 0.0 s; Wait for Temperature selected as On; Wait for axial force selected as Off; Preshear Options selected Perform Preshear as On and shear rate set to 100 s. -1 and set Duration to 60.0 seconds; set Equilibrium by selecting Perform Equilibration as On; and set Duration to 1,800.0 seconds.

[0090] The flow peak hold step is performed using the following instrument settings: Set Environmental Control with a temperature of 25°C;Select Inherit Set Point as Off;Set Soak Time to 0.0s;Select Wait for Temperature as Off;Set Test Parameters with a Duration of 3,000.0s;Select Shear Rate and set it to 0.01s-1;Select Inherit initial value as Off;Select Sampling interval and set it to 3.0s / pt;Select Motor mode as Auto and set Controlled Rate Advanced;Set Data acquisition with End of step as Zero torque;Set Fast Sampling as Off;Select Save image as Off;Set Step Termination with Limit Checking Enabled as Off;Select Equilibrium Enabled as Off;Select Step Repeat Enabled as Off.

[0091] The yield stress is calculated from the data collected during the flow peak hold step in the following manner: data points are plotted as Percent Stain (%) on the x-axis versus stress (mPa) on the y-axis. Yield stress is determined by selecting the "Analysis" tab, then selecting "Signal max" from the Function drop-down list, and finally selecting "Analyze" within the Commands category. For continuous data sets (containing a single stress value greater than zero for each time value), if the value of "Max Y" occurs at the first 2,500% strain, then the yield stress is equal to the value of "Max Y" and proceed to the second Conditioning Sample Step and Flow Sweep Step.

[0092] However, if "Max Y" occurs after the first 2,500% strain when the Shear Rate is set to 0.01 s-1, load a new sample, set the Shear Rate in the Flow Peak Hold Step to 0.03 s-1, and then repeat the first Conditioning Sample Step and Flow Peak Hold Step. Repeat the calculation of Yield Stress. Yield Stress will be equal to the value of "Max Y" if it occurs at the first 2,500% strain, and proceed to the second Conditioning Sample Step and Flow Sweep Step.

[0093] However, if "Max Y" occurs after the first 2,500% strain when the Shear Rate is set to 0.03 sec-1, load a new sample, set the Shear Rate in the Flow Peak Hold Step to 0.10 sec-1, and then repeat the first Conditioning Sample Step and Flow Peak Hold Step. Repeat the calculation of Yield Stress. Yield Stress is equal to the value of "Max Y" if it occurs at the first 2,500% strain, and proceed to the second Conditioning Sample Step and Flow Sweep Step.

[0094] However, if "Max Y" occurs after the first 2,500% strain when the Shear Rate is set to 0.10 sec-1, load a new sample, set the Shear Rate in the Flow Peak Hold Step to 0.30 sec-1, and then repeat the first Conditioning Sample Step and Flow Peak Hold Step. Repeat the calculation of Yield Stress. Yield Stress is equal to the value of "Max Y" if it occurs at the first 2,500% strain, and proceed to the second Conditioning Sample Step and Flow Sweep Step.

[0095] However, if "Max Y" occurs after the first 2,500% strain when the Shear Rate is set to 0.30 sec-1, then load a new sample and set the Shear Rate in the Flow Peak Hold Step to 1.00 sec-1, then repeat the first Conditioning Sample Step and Flow Peak Hold Step. Repeat the Yield Stress calculation. Yield Stress is equal to the value of "Max Y" if it occurs at the first 2,500% strain; if there is a "Max Y" value or if "Max Y" occurs after the first 2,500% strain, then Yield Stress is equal to zero.

[0096] Load new sample. A second sample conditioning step is performed using the following instrument settings: set Environmental Control at a temperature of 25° C.; select Inherit Set Point as Off; set Soak Time to 10.0 seconds; select Wait for Temperature as Off; select Wait for axial force as Off; set Preshear Options by selecting Perform Preshear as Off; set Equilibrium by selecting Perform Equilibration as On; and set Duration to 1,800.0 seconds.

[0097] The flow sweep process is performed using the following instrument settings: Set Environmental Control with a temperature of 25°C;select Inherit Set Point as Off;set Soak Time as 0.0 seconds;select Wait For Temperature as Off;select Logarithmic Sweep and set Test Parameters;select Shear Rate as 1.0e-3 seconds-1 to 1000.0 seconds-1;set Points Per Decade as 5;select Steady State Sensing as On;set Max Equilibration Time as 45.0 seconds;set Sample Period as 5.0 seconds;set %Tolerance as 5.0;set Consecutive Within as 3;select Scaled Time Average as Off;select Motor Mode as Auto and set Controlled Rate Advanced;select Save Point Display as Off and set Data Acquisition;select Save image as Off;select Limit Checking Enabled as Off and set Step Termination;select Equilibrium Enabled as Off;select Step Repeat Enabled as Off.

[0098] Viscosity is calculated from the data collected in the Flow Sweep Test, is expressed in mPa·s, and is determined to be the "infinite velocity viscosity" by selecting "Best Fit Flow (viscosity vs. velocity)" for the viscosity curve in the analysis portion of the program.

[0099] Spray velocity test method The composition is contained in an airtight pressure pot and pressurized with a nitrogen headspace where the pressure is maintained with a pressure regulator. When the flow control valve is open, the composition flows through a fixture that holds the manifold and nozzle of the trigger sprayer directly into the beaker for 10 seconds. The Spray Rate is the number of grams collected in the beaker per second. The manifold and nozzle can be modified to accommodate multiple nozzle designs (Table 6).

[0100] Spray D(90) normalization and spray D(4,3) normalization test method A Malvern Spraytec 2000 laser diffraction spray droplet sizing instrument (supplied by Malvern Instruments, Worcestershire, UK) equipped with a 300 mm lens with a focal length of 150 mm, and an air purge system (up to 14.5 psi) was used to determine spray droplet volume size distribution measurements including spray D(90) normalized and spray D(4,3) normalized values. The system was controlled by a computer and software accompanying the instrument, such as Spraytec software version 3.20 or equivalent, which utilizes Mie theory and Fraunhofer approximation optical theory. With an air flow rate of 50-70 L / min (60 L / min was the target rate), the system was placed in a fume hood for atmospheric control, taking care to position it directly opposite the operating spray plume trajectory to prevent saturation conditions. The distance from the dispensing nozzle orifice to the laser during measurements was 15 cm. During spray droplet analysis, each sample was dispensed from a pressurized system set at a constant pressure. A new trigger sprayer and a new nozzle were used for each sample replicate analyzed. Lighting conditions were not changed during or between background control and test sample data collection periods. Light obscuration values ​​of less than 95% were considered adequate to provide accurate results.

[0101] A spray measurement was performed using the following spray SOP equipment configuration. The Rapid SOP type was selected and the following settings were selected: Hardware Configuration was set to "Default", Measurement Type was set to "Rapid", Data Acquisition Rate was set to "250Hz", and Lens Type was set to "300". In the Measurement menu: Background was set to "2 seconds", Inspection was selected, and the boxes under Output Trigger were unchecked. Under the Measurement tab, "Rapid" was selected, Events Number was set to "1", Duration Per Event was set to "4000.0", and Units was set to "ms". In Measurement Trigger, Trigger Type was set to "Transmission drops to level" and Transmission was set to "96". In Data Collection, Start was set to "0.0", Units was set to "ms", and "before the trigger" was selected from the drop-down menu. In the Advanced tab window, all boxes were unchecked and Grouping was set to "no grouping". Background Alarms were set to "default values". In the Analysis tab, under Optical Properties, I set Particle Set to "Water", Dispersant to "Air", and set Multiple Scattering Analysis to "Enable". In the Data Handling tab, I set the bottom of Detector Range to "first-8 and last", selected the "No extinction analysis" box, and set the Scattering threshold to "1". In Data Handling / Spray Profile I set the Path Length to "100.0", selected Alarm, and checked the "Use default values" box.In the Additional Properties tab, Curve Fit was set to "no fit", User Size was set to "enable box", and the drop-down menu was set to "Default". In the Additional Properties / Advanced tab, Particle Diameter was set to a minimum of "0.10" and a maximum of "900", and Result Type was set to "Volume Distribution". In the Output tab, Export Option was set to "not selected", Derived Parameter was selected, and the Use Averaging Period box was selected and set to "0.0" and "ms". In the Average menu, "Average scatter data" was selected. Spray measurements were made using the following spray procedure: The sample was first test sprayed from the sprayer for 1-2 seconds to ensure that the nozzle was flowing easily and not clogged; the sample was attached to the gripping device in front of the Spraytec2000 system. The sprayer was sprayed at constant pressure for 6 seconds. Spray droplet size data was observed and saved as "Average Scatter Data".

[0102] All measurements were performed using specified instrument configuration procedures and with great care to ensure that the applied pressure was the same for all samples.

[0103] D(90) and D(4,3) were values ​​obtained from the instrument software for both the experimental and control samples separately.

[0104] Each of the Spray D(90) Normalized, Spray D(4,3) Normalized, Spray D(10) Normalized, Spray D(50) Normalized, and Spray D(3,2) Normalized values ​​reported for each of the samples in Example Table 5 is an average value calculated from five replicate spray plumes per sample.

[0105] Spray Pattern Test Method The sprayer is fixed 15 cm away from a piece of high contrast pH paper measuring 20 cm x 20 cm. The pH paper is held flat and positioned so that the plane created by the large surface of the paper is aligned vertically (parallel to gravity) to the bench top. The output of the sprayer is oriented so that the initial output from the nozzle is parallel to the bench (perpendicular to gravity) and aligned directly to the center of the pH paper. The composition is sprayed for exactly 0.5 seconds at a constant pressure of either 72 psi (Table 7) or 94 psi (Table 8), which leaves a pattern on the pH paper. The radius of the pattern on the pH paper is the longest measured by using a line gauge to measure the distance from the center of the pH paper to the edge of the pattern while avoiding the entire pattern. The diameter of the spray pattern is calculated as twice the radius and is reported in mm. EXAMPLES

[0106] [Table 2]

[0107] Preparation of aqueous premix (solution 1) A prepared aqueous premix containing water and salt was prepared in a 1,000 L mixing tank. Water (1) was added to the mixing tank in the amount shown in Table 2. A stirrer was used to vigorously stir in the water. The remaining ingredients were added in the amounts shown in Table 2, and stirring was continued until all materials were completely dissolved.

[0108] [Table 3]

[0109] Preparation of 1 wt% xanthan gum stock solution (Solution 2) A xanthan gum stock solution was prepared to ensure hydration of the gum before further processing. 40,000 grams of a 1% by weight xanthan gum solution is prepared using a Quadro CC0 high shear mixer equipped with a powder feeder. Dry xanthan gum powder (8) is forced through the feeder with a precise amount of water (1) to create a 1% by weight solution. These mixtures are allowed to equilibrate for 24 hours without stirring to ensure complete hydration of the gum before use.

[0110] Preparation of 1 wt% konjac gum stock solution (Solution 3) A konjac gum stock solution was prepared to ensure hydration of the gum before further processing. 40,000 grams of a 1 wt% konjac gum solution is prepared using a Quadro CC0 high shear mixer equipped with a powder feeder. Dry konjac gum powder (7) is forced through the feeder with a precise amount of water (1) to create a 1 wt% solution. The mixture is allowed to equilibrate for 24 hours without stirring to ensure complete hydration of the gum before use.

[0111] Preparation of the final composition (solution 4) Preparation of the final composition was accomplished by adding both the gum premix and all final ingredients to a mix tank. For the first addition, 31,400 grams of the konjac gum premix (solution 3) was added to the mix tank along with the composition previously described (solution 1) and mixed thoroughly. For the next addition, 21,000 grams of the xanthan gum premix (solution 2) was added to the mix tank and mixed thoroughly. The composition is continuously mixed until a yield stress greater than 0 is measured by the Rheology Test Method. For the final addition, the remaining ingredients are added in the amounts described in Table 3 and mixed thoroughly to reduce the flavor particle size consistent with the specifications.

[0112] [Table 4]

[0113] The final composition (Solution 4) was loaded into a pressure pot for spray measurements. The spray assembly was equipped with a nozzle (Table 6). The pressure pot was pressurized to either 72 psi or 94 psi with nitrogen. The droplet size distribution of the spray at each pressure and each nozzle was measured by the Spray D(90) Normalized and Spray D(4,3) Normalized test methods. The spray velocity at each pressure and each nozzle was measured by the Spray Velocity test method. The spray pattern at each pressure and each nozzle was measured by the Spray Pattern test method. The results are shown in Tables 5 and 6 for each pressure.
