Description:
FIELD 
       [0001]    The present disclosure relates to improved aqueous freshening compositions and freshening products comprising the aqueous freshening compositions contained in pressurized plastic containers. 
       BACKGROUND 
       [0002]    Pressurized containers for dispensing freshening compositions are known in the art and are typically constructed of metal in order to withstand the internal pressure of aerosols. Pressurized plastic containers containing a freshening composition may be desirable for cost, aesthetic (e.g. clear container), and recyclability advantages. It has been found, however, that the interaction of the perfume mixtures present in freshening compositions with plastic containers, especially when under pressure, may result in a phenomenon called crazing. Crazing is the appearance of small cleaves in the plastic, resembling cracks. Crazing is believed to be affected by the morphology of the plastic container, the strain on the container, and/or the chemistry of the composition contained in the container. Crazing is undesirable from both an aesthetic and functional point of view. 
         [0003]    Manufacturers have attempted many techniques to minimize/avoid crazing in pressurized plastic containers due to certain chemical interactions of the formulations contained therein. These techniques include adjusting geometries and thicknesses of the container wall, applying a coating layer to the container wall, crystallizing certain portions of the container, and adjusting certain formulation chemistries. Attempts to overcome crazing problems are shown, for example, in U.S. Pat. No. 7,303,087 and WO 2011/088093. However, these approaches have not proven entirely satisfactory where a perfume mixture may be the primary active in the formulation (e.g. air freshening sprays). Further, some of the previous approaches require added production steps and/or costs (e.g. crystallizing neck portions, adding coatings, and constructing thicker walls than required for safety) and may be viewed as environmentally unfriendly. 
         [0004]    As such, there remains a need for improved aqueous freshening compositions that minimize crazing in pressurized plastic containers.

         [0066]    The aqueous freshening composition may be substantially free of or free of a flavorant. A flavorant is an edible chemical that is added to food and beverage products to alter the taste of the food or beverage product. Where a perfume mixture is free of a flavorant, the perfume mixture is free of flavorants including perfume raw materials that are known to be used as flavorants in the food and beverage industry. Having a perfume mixture that is free of flavorants can help provide improved hedonic benefits of the aqueous freshening composition. 
         [0067]    Aqueous Carrier 
         [0068]    The aqueous freshening composition also comprises an aqueous carrier. The aqueous carrier which is used may be distilled, deionized, or tap water. Water may be present in any amount for the composition to be aqueous. In some embodiments, water may be present in an amount of about 70% to about 99.9%, or about 80% to about 99.9%, or about 85% to 99.9%, or about 90% to about 99.5%, or about 92% to about 99.5%, or about 95%, by weight of said aqueous freshening composition. 
         [0069]    Additional Ingredients 
         [0070]    The aqueous freshening composition may also have less than about 30%, or less than about 10%, or less than about 5%, by weight of the composition, of alcohol. However, the volatile low molecular weight monohydric alcohols such as ethanol and/or isopropanol should be limited since these volatile organic compounds may contribute both to flammability problems and environmental pollution problems. If small amounts of low molecular weight monohydric alcohols (e.g., ethanol, methanol, and isopropanol, or polyols, such as ethylene glycol and propylene glycol) may be in present in the composition due to the addition of these alcohols to such things as perfumes and as stabilizers for some preservatives, the level of monohydric alcohol may be about 1% to about 5%, alternatively less than about 5%, by weight of the aqueous freshening composition. 
         [0071]    The aqueous freshening composition of the present disclosure may be formulated into an aerosol freshening composition comprising malodor counteractants, particulate controlling polymers, emulsifiers and solubilizing surfactants to solubilize any excess hydrophobic organic materials, particularly any perfume raw materials. Other emulsifiers, solvents, solubilizers and surfactants as described in U.S. Pat. No. 7,998,403 or in US 2012/0288448A1 can be used to enhance performance of the aqueous freshening composition. A suitable solubilizing surfactant, is a no-foaming or low-foaming surfactant. In one embodiment, the aqueous freshening composition contains ethoxylated hydrogenated castor oil. One suitable hydrogenated castor oil is Basophor™, available from BASF. The solubilizer to perfume ratio in aqueous freshening composition may be about 2:1 or greater than 2:1. 
         [0072]    Pressurized Plastic Container 
         [0073]    The aqueous freshening compositions of the present disclosure have been found to be compatible with and useful in pressurized plastic containers. “Plastic” refers to any synthetic or organic material that can be molded or shaped, generally when heated, and then hardened into a desired form including, but not limited to, polymer, resin, and cellulose derivative. The plastic may be polymeric and may be partially, substantially, or entirely comprised of polyester; polyethyleneterephthalate (“PET”); polyethylene napthalate, polyethylene furanoate, polyamide; nylon 6/6, nylon 66, nylon 11, polycarbonate; polyoxymethylene; polyacrylonitrile; polyolefin; polyethylene, polypropylene, fluoropolymer; poly(butylene succinate); virgin, recycled, and regrind versions of the other polymer materials; bio-based and petroleum-based versions of the other polymer materials; and mixtures thereof. The pressurized plastic container may comprise multiple layers of other polymer materials. By polymeric it is meant that the component is formed of a material which is plastic, comprises polymers, and/or particularly polyolefin, polyester or nylons. Thus, the entire pressurized plastic container or, specific components thereof, may be free of metal, allowing for exposure to microwave energy. 
         [0074]    Referring  FIGS. 1 and 2 , as the top of plastic container  10  is approached, the plastic container may have an opening  21 . An optional crimp ring  21 C may be circumjacent, and in a degenerate case circumscribe the opening  21 . The optional crimp ring  21 C may provide for attachment of an optional valve cup as is known in the art. 
         [0075]    Below the optional crimp ring  21 C, is a neck  24 . The neck  24  may be of constant or variable cross section. The neck  24  may have an optional flange  24 F. The optional flange  24 F may extend radially outward from the neck  24 , as shown and/or may extend radially inwardly. The flange  24 F may circumscribe the neck  24  or may be interrupted at various positions around the circumference to be discontinuous. The plastic container  10  may have a step in the outer wall of the neck  24 . Such a plastic container may be made according to U.S. Pat. No. 6,971,530. The flange  24 F may be disposed near the axial center of the neck  24 , as shown, or may be juxtaposed with the top or bottom of the neck  24 . The flange  24 F may divide the neck into an upper portion  24 U and a lower portion  24 L. The neck  24  may have a lesser thickness at the top portion  24 U than at lower portion  24 L, or vice versa, to provide a differential thickness. 
         [0076]    The lower portion  24 L of the neck  24  may be above and/or superjacent the shoulder  25  of the plastic container  10 . The shoulder  25  may flare radially outwardly from the lower portion  24 L in a first transition region. The shoulder  25  may connect to the container sidewall  29 . The shoulder  25  may particularly be joined to the sidewall  29  by a radius or second transition region. The plastic container  10  sidewall also defines a diameter if a round cross section is selected for the body. 
         [0077]    The plastic container  10  is pressurized to an internal gage pressure of about 345 kPa (55 psi) to about 1100 kPa, or from about 414 kPa to about 1100 kPa, or from about 460 kPa to about 1100 kPa, or from about 480 kPa to about 1100 kPa, or from about 500 to about 1100 kPa, or from about 550 kPa to about 1100 kPa, or from about 600 kPa to about 1100 kPa, or from about 690 kPa (100 psi) to about 1100 kPa, or about 827 kPa (120 psi) to about 1100 kPa, or 935 kPa (135 psi) to about 1100 kPa. 
         [0078]    A plastic container  10  having a crystallized neck may be pressurized to an internal gage pressure of up to 1300 kPa, preferably 345 kPa to 1300 kPa, or 414 kPa to about 1100 kPa, or from about 460 kPa to about 1100 kPa, or from about 480 kPa to about 1100 kPa, or from about 500 to about 1100 kPa, or from about 550 kPa to about 1100 kPa, or from about 600 kPa to about 1100 kPa, or from about 690 kPa (100 psi) to about 1100 kPa, or about 827 kPa (120 psi) to about 1100 kPa, or 935 kPa (135 psi) to about 1100 kPa or preferably from about 460 kPa to about 1100 kPa. 
         [0079]    The final gage pressure of the plastic container is 0 when the propellant is fully discharged from the container. Where residual aqueous freshening composition remains, the final gage pressure may be from about 0 to about 120 kPa. 
         [0080]    The pressurized plastic container  10  includes a propellant. Any suitable propellant may be used. The propellant may comprise a compressed gas such as, nitrogen, carbon dioxide, compressed air, and mixtures thereof. The propellant may comprise a liquefied gas or hydrofluoro olefin (“HFO”) propellant. If a liquefied gas propellant is used, the pressurized plastic container may include a bag-in-bottle configuration. Propellants listed in the U.S. Federal Register 49 C.F.R. §1.73.115, Class 2, Division 2.2 are considered acceptable. The propellant may particularly comprise a trans-1,3,3,3-tetrafluoroprop-1-ene, and optionally a CAS number 1645-83-6 gas. Such propellants provide the benefit that they are not flammable, although the composition is not limited to inflammable propellants. One such propellant is commercially available from Honeywell International of Morristown, N.J. under the trade name HFO-1234ze or GWP-6. 
         [0081]    If desired, the propellant may be condensable. By “condensable”, it is meant that the propellant transforms from a gaseous state of matter to a liquid state of matter in the container and under the pressures encountered in use. Generally, the highest pressure occurs after the container is charged with product but before that first dispensing of that product by the user. A condensable propellant provides the benefit of a flatter depressurization curve as product is depleted during usage. 
         [0082]    The volumetric ratio of aqueous freshening composition to propellant may be in the range of about 40/60 to about 70/30, alternatively in the range of about 50/50 to about 60/40. 
         [0083]    The aqueous freshening composition is delivered from the pressurized plastic container  10  which includes delivery components including but not limited to a valve to control flow and to seal the composition within the pressurized plastic container, a button actuator and a nozzle for dispensing the composition to the environment. 
         [0084]    The aqueous freshening composition may contact the inner face of the plastic container  10  and is not contained in a plastic container by a bag-in-can or a plastic container comprising a liner. 
         [0085]    In other embodiments, the aqueous freshening composition may be contained in a bag-in-can or bag-in-bottle plastic container. 
         [0086]    The pressurized plastic container may hold from about 20 grams to about 300 grams, or at least about 20 grams, or at least about 120 grams, or at least about 130 grams, or at least about 150 grams. 
         [0087]    The container comprises a hoop tensile strain from about 0.1% to about 2%, or from about 0.1% to about 1%, or from about 0.2% to about 0.6%. “Hoop tensile strain” is the resultant material deformation as a function of the internally applied force exerted circumferentially (perpendicular to the major longitudinal axis LA on every particle in the cylinder wall of a plastic container and is represented as a % value derived from the hoop tensile strain test method set forth below. 
         [0088]    Crazing of about 1 mm or greater through a plastic PET is typically visible to the human eye and may compromise product aesthetics. It may compromise the function of the container under use conditions (e.g. may result in container becoming more brittle or rupturing when force is applied to it, for example, container dropping). Typically, the deeper the craze through the plastic material, the more compromised the integrity of the plastic becomes. 
         [0089]    Preferably, the freshening product is stable in the pressurized plastic container for 1 year, more preferably 2 years, more preferably 3 years, most preferably 5 years. 
         [0090]    The total composition output and the spray droplet/particle size distribution may be selected to support the particulate removal efficacy but avoid a surface wetness problem. Total output is determined by the flow rate of the composition it is released from the spray dispenser. To achieve a spray profile that produces minimal surface wetness, it is desirable to have a low flow rate and small spray droplets. 
         [0091]    Flow rate is determined by measuring the rate of composition expelled by a container for any 60 seconds period of use. The flow rate of the composition being released from the spray dispenser may be from about 0.0001 grams/second (g/s) to about 2.5 grams/second. Alternatively, the flow rate may be from about 0.001 grams/second to about 1.8 grams/second, or about 0.01 grams/second to about 1.6 grams/second. 
         [0092]    The mean particle size of the spray droplets may be in the range of from about 10 μm to about 100 μm, alternatively from about 20 μm to about 60 μm. At least some of the spray droplets are sufficiently small in size to be suspended in the air for at least about 10 minutes, and in some cases, for at least about 15 minutes, or at least about 30 minutes. 
         [0093]    Small particles can be efficiently created when the spray is dispensed in a wide cone angle. For a given nozzle component and delivery tube, cone angles can be modified by varying the insertion depth of the nozzle in the delivery tube. The cone angle may be greater than about 20 degrees, or greater than about 30 degrees, or greater than about 35 degrees, or greater than about 40 degrees, or greater than about 50 degrees. 
         [0094]    The spray dispenser may be configured to spray the composition at an angle that is between an angle that is parallel to the base of the container and an angle that is perpendicular thereto. The desired size of spray droplets can be delivered by other types of spray dispensers that are capable of being set to provide a narrow range of droplet size. Such other spray dispensers include, but are not limited to: foggers, ultrasonic nebulizers, electrostatic sprayers, and spinning disk sprayers. 
         [0095]    The aqueous freshening composition may also be formulated for use in personal care products such as skin moisturizers, body deodorants, facial and body cleansers, baby wipes; surface care compositions such as hard surface cleaners, wood polishes, and automobile cleaners; fabric care compositions such as cleaners, softeners, de-wrinklers, and refreshers; and air freshening compositions including aerosols and sprays. 
         [0096]    The freshening products may be used to freshen the air, surfaces, fabrics, and/or combinations thereof. 
         [0097]    Test Method to Determine % Hoop Tensile Strain at Neck—Measurement of Pressurized Plastic Aerosol Container Strain 
         [0098]    Optical (photographic 2D), X-ray (Computed Tomography 3D), or equivalent imaging techniques may be used to quantify the level of strain at specific locations on a pressurized aerosol container. The % hoop tensile strain determination is made by imaging the region of interest with and without pressure. Relative dimensional changes are used to calculate % hoop tensile strain. 
         [0099]    Sample Preparation 
         [0100]    Procure a minimum of six unused pressurized plastic aerosol containers and condition them for 24 hours in the ambient environment (24° C.+/−3° C.) prior to imaging. 
         [0101]    Imaging 
         [0102]    Secure each conditioned plastic container by the upper neck  24 U in a collet or equivalent clamping device to keep the container stable and to prevent contact with surrounding surfaces. Orient the containers, relative to the imaging device, such that at least three containers will be imaged, displaying their widest diameter of the neck  24  and at least three other containers will be imaged displaying their smallest diameter of the neck. The container temperature, when imaged, should be held constant across the pressurized and unpressurized conditions. 
         [0103]    For each sample, optimize the resolution by only imaging the region of interest—the lower neck  24 L and filling the field of view. Fix the imaging device field of view/focal plane. Place a scale that occupies the field of view in the focal plane and capture the image to set the image scale. The minimum resolution is 100 pixels/mm or 64,000 voxels/mm 3 . Place the plastic container in the field of view/focal plane and capture the image using appropriate imaging techniques to maximize contrast between the plastic container and the environment. Relieve the aerosol pressure without moving the plastic container or altering the position of the field of view or focal plane. Allow the unpressurized plastic container to equilibrate for a minimum of 1 hour so that the external pressure is equal to the internal pressure, while ensuring that there is no movement of the plastic container, the field of view, or the focal plane. Capture the unpressurized plastic container image under the same imaging conditions as the pressurized plastic container. 
         [0104]    Image Analysis: 
         [0105]    Using appropriate image analysis software, such as Image J (National Institutes of Health, Bethesda, Md., U.S.A.), or Geomagic Studio (Geomagic Inc., Morrisville, N.C., U.S.A.), set the dimensional scale in the images (pixels/mm or voxels/mm 3 ) by using the previously captured scale image. Measure the outside diameter (“OD”) of the pressurized lower neck  24 L image at 1 mm increments, defined as starting 1 mm below the flange  24 F or below the neck  24  MidPoint MP and extending 5 mm vertically toward the bottom of the container  10 , generating a total of 6 OD measurements as denoted with lines  24 W shown in  FIG. 3 . Precisely identify the six locations where outside diameters were measured in the pressurized neck image, then remeasure the outside diameter at these same six locations in the unpressurized neck image. Convert the linear outside diameter dimensional change to % hoop tensile strain per the following equation, and report the maximum % hoop tensile strain value from the six locations measured on each container: 
         [0000]      % Hoop Tensile Strain at location  x =(ODP x −ODU x )/ODP x *100
 
         [0106]    where ODP x =Outside diameter pressurized at location x, where x=1 to 6; where ODU x =Outside diameter unpressurized at location x, where x=1 to 6; and where the strain value recorded for each container is the maximum value obtained from the six locations measured. The % Hoop Tensile Strain value reported is the maximum strain value recorded from the six (or more) individual containers imaged.

         [0108]    Imaging 
         [0109]    Image lower neck  24 L, capturing the full width  24 W while setting the focal plane at the maximum neck diameter. Image pressurized and post pressurization region as instructed in the imaging section above.

         [0110]    Referring to  FIG. 4 , the plastic container  10  may not have the optional flange  24 F. In such case, the hoop tensile strain may be taken as a region below the axial midpoint MP of the neck  24 . In determining the axial midpoint MP of the neck  24 , only the portion of the neck  24  having constant cross section, if present, is considered. If the neck  24  has a variable cross section, the axial midpoint MP is that point of the neck  24  intermediate and midway between the underside of the optional crimp ring  21 C and the start of the shoulder  25 . If the plastic container  10  does not have a crimp ring  21 C, the top of the neck  24  is utilized instead. The axial midpoint MP of the neck  24  may be used in addition to or in place of the flange  24 F for purposes described and claimed herein. 
         [0111]    As measured maximum strain levels in amorphous bottle neck regions can be replicated utilizing amorphous PET test bars. Standard test bars, about bottle neck thickness, are injection molded utilizing bottle PET under conditions replicating preform molding. Inverted bottle neck (internal formula contact) craze formation has been found to correlate with immersed test bar results. Strained test bars can be used to quickly quantify crazing potential of formulations in direct contact with amorphous PET. 
         [0112]    Test Method to Determine Crazing Effect of Perfume Raw Materials and Plastic Material Under Strain 
         [0113]    To simulate hoop tensile strain of a pressurized plastic container, injection molded PET test bars of about 127 mm long×12.7 mm wide×3.1 mm thick were clamped to individual curved stainless steel fixtures, putting the outer surface of bars under bending strain per equation: 
         [0000]      ε= h /( d+h )
 
         [0114]    Where 
         [0115]    h=thickness of test bars (eg. mm, m, in) 
         [0116]    d=diameter of fixture (eg. mm, m, in) 
         [0117]    ε=unit less measure of strain 
         [0118]    ε%=*100 
         [0000]    ISO 22088-3/2006 describes details for determining strain test parameters. The test bars were molded to intrinsic viscosity of about 0.79±0.02 dl/g per ASTM D4603, with an average maximum molded IV drop of 0.06 dl/g vs starting PET resin pellets. 
         [0119]    Test bars of similar age range were used for these comparative studies as PET properties can change over time with storage conditions (temperature, humidity). Test bars used for these experiments were stored at room temperature (about 24±3 C) for a maximum of one month after initial molding; otherwise, test bars were annealed to about 10° C. above glass transition temperature for about 15 minutes and cooled slowly on a flat inert surface to prevent warping. Post annealing or injection molding, all bars are conditioned/equilibrated at room temperature for minimum of two hours before clamping on test fixtures. 
         [0120]    Formulation samples were prepared as discussed below with regard to Tables 6 and 8. The formulation ingredients were mixed together to create clear and single phase solutions. The PRM, surfactants, emulsifiers and solvents were premixed together as needed to emulsify the PRM into solution. All surfactants, emulsifiers, buffers, stabilizers in Tables 6 and 8 are identical and were previously tested to ensure no additional impact on test bars. 
         [0121]    The whole fixtures were totally immersed in sealed glass containers with formulations indicated in Tables 6, 7, 8, and 9 and then stored at room temperature for 24 hours. The bars were then removed from the glass containers, rinsed with DI water, and allowed to dry. The test bars were then placed under a microscope and oriented relative to the imaging device and LED light source, such that the full thickness in the middle of the bar is in field of view. Images were then captured using calibrated imaging scale, with a minimum of 100 pixels/mm The depth of the deepest craze observed on each test bar was measured using appropriate image analysis software, such as DinoCapture (Energiestraat, Naarden, The Netherlands), Image J (National Institutes of Health, Bethesda, Md., U.S.A.), or Geomagic Studio (Geomagic Inc., Morrisville, N.C., U.S.A.). 
         [0122]    % Crazed is then calculated by: 
         [0000]      (Deepest Craze Depth(mm)/Total Thickness of Bar(mm)*100 
         [0123]    The higher the % Crazed, the less compatible the formulation is with the pressurized plastic container; conversely, the lower the % Crazed, the more compatible and less interactive the formulation is with the pressurized plastic container 
         [0124]    At least 3 test bars were evaluated per formulation and then % Crazed is averaged per formulation tested. 
         [0125]      FIG. 5  illustrates visual examples of crazing observed at different % Crazed ranges. Crazing of 20% or less is virtually negligible, crazing below 40% is considered minor and may not be visible to the typical human eye. Crazing above 40% is typically visible and may be consumer unacceptable aesthetically. Crazing above 60% is very visible to the human eye and may also compromise the function of the container under use conditions (e.g. may result in container rupturing when force is applied to it, for example, container dropping). 
         [0126]    Perfume Raw Material Interaction with Plastic Material Under Strain 
         [0127]    Formulations were prepared to test the effect of individual PRMs on plastic with and without strain. Formulations were prepared according to Table 6, with each formulation comprising one of the PRMs from Table 7. Thus, a total of 58 formulations were prepared. Each sample is formulated with 0.6% of the indicated PRM on Table 7. A base formulation with no PRM was also tested for calibration. Each formulation was evaluated with test bars at 1.0% strain vs. a control with no strain using the Test Method to Determine Crazing Effect of Perfume Raw Materials and Plastic Material Under Strain described above. 
         [0000]                                              TABLE 6                           Wt %                                        Individual Perfume Raw Material   0.6           (PRM) Indicated per Table 7               Surfactants &amp; Emulsifiers   1.8           Buffers &amp; Other Stabilizers   0.4           Cyclodextrin derivative   0.15           Ethanol   5           Water   To 100                        
As demonstrated in Table 7, the perfume materials do not induce crazing when the plastic is not under strain, simulating how perfume material will act in unpressurized conditions. As seen with test bars at 1% Strain, the PRMs cause crazing at different level depending on the type of PRM.

Each PRM listed in Table 9 was tested in the aqueous perfume composition of Table 8 at 0.01%, 0.05%, 0.1%, 0.6% and 1.2% by weight of the aqueous freshening composition. A control with no PRM is also tested. All the formulations were tested at 1% Strain according to the Test Method to Determine Crazing Effect of Perfume Raw Materials and Plastic Material Under Strain described above.

The results are reported in Table 9 above and in  FIG. 6 . The results in Table 9 and  FIG. 6  demonstrate that crazing is initiated at certain critical concentrations (wt. %) for different types of PRMs. All of the PRMs tested show no or negligible crazing up to 0.1% in aqueous formulation. It can also be observed that crazing begins to plateau for most PRMs after a certain concentration. It is shown that Highly Compatible PRMs like benzaldehyde and pyranol exhibit no to negligible crazing at all levels tested. Controlled and Limited PRMs start to show minor crazing at about 0.3 wt % and do not reach visible Craze % (% Craze above 40%) until about 0.6 wt. %.
