This invention relates to freshening compositions, preferably liquid freshening compositions, more preferably liquid air freshening compositions. This invention also relates to non-water-based freshening compositions, preferably non-water based liquid freshening compositions, more preferably non-water-based liquid air freshening compositions. Freshening compositions of the present invention may comprise one or more of a perfume raw material, a solvent, and a fragrance release modulator. The invention also relates to air care products and devices comprising a freshening composition. Further, the invention relates to methods for formulating a freshening composition, methods for manufacturing an air care product or device comprising a freshening composition, methods for using a freshening composition to freshen the atmosphere, the air, or a surface, and methods for modulating the release of a freshening composition or of a component thereof.
Air care products, such as wicking-based, diffusion-based, spraying-based, or steam-based products have been commonly used to deliver various freshening compositions into the air or onto a surface. Exemplary freshening compositions used with such air care products may include volatile materials such as perfume compositions, perfume compositions in conjunction with malodor counteracting compositions, perfume compositions in conjunction with insect repelling compositions, or perfume compositions in conjunction with antimicrobial compositions.
When an air care product is based on a wicking releasing mechanism it mainly consists of (i) a liquid freshening composition, (ii) a container, (iii) a delivery element, which can be a wick or a plurality of wicks, a reed or a plurality of reeds, a stick or a plurality of sticks, a fiber or a plurality of fibers, a mesh, a porous or semi-porous substrate, and, optionally, (iv) an evaporation assisting device, such as in-wall electrical plug-in device, a heating device, or a fan. Commonly known air care products based on a wicking releasing mechanism include reed diffusers, wall electrical plug-ins and diffusers associated with a fan or heating system.
Diffusion-based air care products mainly consist of (i) a liquid freshening composition, (ii) a container, (iii) a diffusing interface, for example a membrane, and, optionally, (iv) a heating device, and (v) an air circulating device, such as a fan, or a combination thereof.
Spraying-based air care products mainly consist of (i) a container for accepting and storing an air freshening composition, which may contain a perfume composition or a perfume composition in conjunction with an active composition, such as a malodor counteracting composition, (iii) a propellant as a compressed gas, and (iv) a dispenser.
Steam-based air care products mainly consist of (i) a liquid freshening composition, (ii) a container, and (iii) a steam forming and releasing device.
Wicking, also known as wicking process, refers to a spontaneous transport of a liquid through a porous medium as a result of capillary suction taking place at liquid-gas interfaces at the surface or within the porous medium. Several wick-based systems designed to release perfumes or insect repellent liquids through a combined action of wicking process and evaporation are known. The performance a customer expects for an air care freshener based on a wicking process may include (i) an immediate hedonic experience, i.e., a strong perceived impression with respect to strength and character of the fragrance, also known in the art as “fragrance burst” or “fragrance blooming,” and simply referred to as, smell, and (ii) a long-lasting hedonic experience, i.e., a long-lasting fragrance strength and character during the lifespan of the air care freshener product. To meet such customer's expectation, there is an imperative and unresolved need to provide and optimize a liquid freshening composition taking into consideration the design, geometrical characteristics, and physical parameters of a device delivering such air freshening composition. Further, the design of an evaporative assistance device, if such an element is involved, needs to be taken in consideration. In other words, a preferred air care product, such as an air care freshener would comprise a releasing profile of the liquid freshening composition that follows a two stage releasing regime: (i) an initial transitory regime, which is associated with an unusually high amount of liquid freshening composition release, and (ii) a steady-state release regime, which would require a linear release of the air care freshening composition into the external environment until, or very close to its full completion. Such an air care freshener product would operate until its entire liquid freshening composition is released into the external environment with no further human intervention. For example, in a reed diffuser, there should be no need to flip the reeds to achieve the above-mentioned hedonic experiences.
Most of the wicking air care fresheners on the current market fail to provide such a release performance. This failure can be attributed mainly due to (i) the lack of an initial transitory regime, which is responsible for the initial fragrance burst, which translates into a fragrance hedonic experience, (ii) the linear release of a freshening composition until its full completion, which is responsible for delivering the need fragrance experience, strength and character, and sometimes (iii) the high amount of residual product left in a reservoir that is not released. Therefore, there is a need in the art to provide an air care freshener satisfying the above-mentioned requirements.
Despite the critical role of the wicking process with respect to the release of the liquid freshening composition, most of the prior art air care products solely address the volatility of the freshening composition with respect to the fragrance delivery performance of an air freshening compositions, which is expressed based on the vapor pressure of the air freshening composition. Hence, it is of no surprise why known air care products are more concerned with (i) the rate of evaporation of a specific freshening composition, e.g., by taking into account the volatility of the fragrance ingredients, and that of solvents and diluents, and (ii) the design of a particular air care freshener device that may enhance the rate of evaporation of an air care freshening composition, such as an electrical external heater or fan.
Wicking air care fresheners known in the art most commonly use as a solvent or diluent glycol ethers and isoparaffines whose vapor pressures are below 0.1 mm Hg. While complying with the requirements imposed by the Environmental Protection Agency (EPA) and The California Air Resources Board (CARB) with respect to atmospheric emission of organic compounds, and more particularly with the restrictions on the emission level of the so-called “volatile organic compounds” (VOC), and displaying good performance to dissolve fragrance ingredients and having acceptable volatility, glycol ethers can impart specific undesired off-notes, which negatively affect the hedonic performance of an air care freshener product. Further, based on the recent ingredient disclosure initiatives (a new norm accepted and embraced by the consumer goods industry to disclose to the customers the names of the ingredients into their products including the fragrance ingredients), glycol ethers are chemicals that become less and less desired, if not undesired, by customers.
Some silicon solvents, which are exempted by the EPA and CARB and not considered being VOC, can also be used in the formulation of a wicking air freshener diffuser. However, due to their fragrance solubility issues and high cost, the use of silicon solvents in air care freshener products is restricted.
The volatility of a freshening composition varies based on the particular compounds of the composition. As the vapor pressure of a freshening composition increases, the rate at which the freshening composition volatilizes, i.e., evaporates, also increases. As a result, the lifespan of an air care product comprising such freshening composition can be dependent upon the particular freshening composition used. In some cases, solvents or diluents are used to slow down the rate of evaporation of a freshening composition. However, adding solvents or diluents to slow down the evaporation rate of a freshening composition may significantly reduce the level of perfume materials in the freshening composition or may even change the character of the freshening composition and its scent characteristics.
Exemplary air freshening devices comprising a water-based fragrance emitter and a means for heating the emitter are described in U.S. Pub. 2018/0064838 A1. The water-based fragrance emitters, e.g., a plurality of water beads, include water, a water-absorbing polymer, and a fragrance composition. The means for heating the emitter, also referred to as warming device, heated water-based fragrance emitter, or fragrance warmer typically include a power supply, a heating element, or a warmer tray (U.S. Pub 2018/0064838 A1). To achieve evaporation of a fragrance composition those devices require structural elements, other than a mere reservoir for the fragrance composition, and elevated temperature.
There is an unfulfilled need for a freshening composition that delivers long-lasting scent. There is an unfulfilled need for a non-water based freshening composition that delivers long-lasting scent. There is an unfulfilled need for a freshening composition that can be evaporated without structural elements, such as a means for heating, to achieve such evaporation. There is an unfulfilled need for a freshening composition that delivers long-lasting scent without heating the freshening composition. There is an unfulfilled need for a freshening composition that delivers long-lasting scent at ambient temperature. There is an unfulfilled need for a freshening composition whose evaporation can be controlled by a chemical compound. There is an unfulfilled need for a freshening composition whose evaporation at ambient temperature can be controlled by a chemical compound. The present invention provides such freshening compositions, air care products and devices comprising same and methods for manufacturing and using same. The present invention also provides methods for modulating the release of a fragrance composition or of a component thereof using a chemical compound.
Further, there is an unfulfilled need for a method to manufacture and to provide an air care freshening wicking product that (i) releases an air freshening composition over a specific period of time without human intervention so that no or very minimal residual amounts of that composition will remain in a reservoir and (ii) provides for a two-stage product releasing regime wherein an initial transitory regime is associated with a high amount of liquid freshening composition release, and wherein a steady-state release regime provides for the linear release of the air care freshening composition into the external environment until, or very close to its full completion. The present invention provides such liquid freshening compositions, air care products and devices comprising same and methods for manufacturing and using same.
Further, there is a long-felt but unmet need in the fragrance industry to control the release of a fragrance or perfume mixture, referred to herein also as freshening composition, or of a component thereof over time. In certain situations, it is desirable to increase, i.e., accelerating or up-regulating the release of a freshening composition or of a component thereof; in others it is more desirable to decrease, i.e., reducing or down-regulating the release of a freshening composition or of a component thereof. The present invention offers an easy and effective solution to that problem and satisfies the long-felt but unmet need.

Throughout the present specification and the accompanying claims, the words “comprise,” “include,” and “have” and variations thereof such as “comprises,” “comprising,” “includes,” “including,” “has,” and “having” are to be interpreted inclusively. That is, these words are intended to convey the possible inclusion of other elements or integers not specifically recited, where the context allows. The term “consisting essentially of” means that the composition, method, or structure may include additional ingredients, steps and/or parts, but only if the additional ingredients, steps and/or parts do not materially alter the basic and novel characteristics of the claimed composition, method, or structure. As used herein, the term “consisting of” is intended to mean including and limited to whatever follows the phrase “consisting of”. Thus, the phrase “consisting of” indicates that the listed elements are required or mandatory and that no other elements may be present. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the invention.
The terms “a” and “an” and “the” and similar referents used in the context of describing the invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context.
The term “and/or” where used herein is to be taken as specific disclosure of each of the two specified features or components with or without the other. For example, “A and/or B” is to be taken as specific disclosure of each of (i) A, (ii) B, and (iii) A and B, just as if each is set out individually herein.
Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, each individual value is incorporated into the specification as if it were individually recited herein. Ranges may be expressed herein as from “about” (or “approximate”) one particular value, and/or to “about” (or “approximate”) another particular value. When such a range is expressed, an embodiment includes values from the one particular value to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about” or “approximate” it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. With respect to endpoints of ranges, it is understood that when a range is given herein, it discloses alternative ranges, without specifically reciting them, i.e., (a) an “of/from-to” range in which the endpoints are included in the range and (b) an “between-and” range, in which the endpoints are excluded from the range. For example, a disclosure of a freshening composition comprising about 0.1 wt % to about 95 wt % perfume raw material includes (a) a composition comprising the perfume raw material from about 0.1 wt % to about 95 wt %, in which the endpoints 0.1 wt % and 95 wt % are included, and (b) a composition comprising the perfume raw material between about 0.1 wt % and about 95 wt %, in which the endpoints 0.1 wt % and 95 wt % are excluded. Thus, every range defined herein in the format “from/of-to” is to be understood as also disclosing a separate and discrete range defined as “between-and.” Likewise, every range defined herein in the format “between-and” is to be understood as also disclosing a separate and discrete range defined as “from/of-to”. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as “about” that particular value in addition to the value itself. For example, if the value “10” is disclosed, then “about 10” is also disclosed. Further, the term “about” applies to both cited endpoints of a range, even when it is written only before the lower endpoint. For example, “about X to Y” should be interpreted as “about X to about Y.” It is also understood that when a value is disclosed that is “less than or equal to the value” or “greater than or equal to the value” possible ranges between these values are also disclosed, as appropriately understood by the skilled artisan. For example, if the value “10” is disclosed the “less than or equal to 10” as well as “greater than or equal to 10” is also disclosed.
In the following description it is to be understood that terms such as “forward,” “rearward,” “front,” “back,” “right,” “left,” “upward,” “downward,” “horizontal,” “vertical,” “longitudinal,” “lateral,” “angular,” “first,” “second” and the like are words of convenience and are not to be construed as limiting terms.
Certain limitations of claim elements are disclosed as Markush groups. It is understood that with the disclosure of a Markush group comprising X members (wherein X is any number), a Markush group missing one or more members, i.e., a Markush group comprising X−1 members, or X−2 members, etc. is disclosed as well. For an illustrative example, where the disclosure provides “a compound is selected from the group consisting of compound A, compound B, compound C, compound D, compound E, compound F, and compound G” the disclosure inherently discloses: “a compound selected from the group consisting of compound B, compound C, compound D, compound E, compound F, and compound G” or “a compound selected from the group consisting of compound C, compound D, compound E, compound F, and compound G”, etc.
All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. Further, all methods described herein and having more than one step can be performed by more than one person or entity. Thus, a person or an entity can perform step (a) of a method, another person or another entity can perform step (b) of the method, and a yet another person or a yet another entity can perform step (c) of the method, etc. The use of any and all examples, or exemplary language (e. g. “such as”) provided herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed.
Units, prefixes, and symbols are denoted in their Système International de Unites (SI) accepted form. The abbreviations used herein have their conventional meaning within the mechanical, chemical, and biological arts.
Groupings of alternative elements or embodiments of the invention disclosed herein are not to be construed as limitations. Each group member may be referred to and claimed individually or in any combination with other members of the group or other elements found herein. It is anticipated that one or more members of a group may be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all Markush groups used in the appended claims.
The headings used herein are for organizational purposes only and are not meant to be used to limit the scope of the description or the claims, which can be had by reference to the specification as a whole. Accordingly, the terms defined immediately below are more fully defined by reference to the specification in its entirety.
Illustrations are for the purpose of describing a preferred embodiment of the invention and are not intended to limit the invention thereto.
Unless defined otherwise, all technical and scientific terms used herein have the meaning commonly understood by a person skilled in the art to which this invention belongs. The following references provide one of skill with a general definition of many of the terms used in this invention: The Cambridge Dictionary of Science and Technology (Walker ed., 1988). As used herein, the following terms have the meanings ascribed to them unless specified otherwise.
As used herein, the terms “about” or “approximately” refer to a range of values of plus or minus 20%, preferably, plus or minus 10%, more preferably, plus or minus 5% of a specified value, and more preferably, plus or minus 4% of a specified value, plus or minus 3% of a specified value, plus or minus 2% of a specified value, plus or minus 1% of a specified value, and/or plus or minus 0% of a specified value. For example, the phrase “about 200” includes plus or minus 20% of 200, or from 160 to 240, preferably, plus or minus 10% of 200, or from 180 to 220, more preferably, plus or minus 5% of 200, or from 190 to 210. It includes, also the specified value or concrete number, e.g., “about 200” includes 200.
Unless otherwise indicated herein or otherwise clearly contradicted by context, a step of “adding” or “combining” a first compound to or with second compound is synonymous with “adding” or “combining” the second compound to or with the first compound. Likewise, if three or more compounds are added to each other or are combined, the order of adding or combining is not critical.
The terms “agent,” “compound,” and “ingredient,” unless clearly contradicted by context, are used interchangeably herein. As used herein, an “agent” can be any chemical compound, for example, a macromolecule or a small molecule.

It includes, but is not limited to, a spray, an energized (e.g., electrically powered) air freshening delivery system, such as a fan-based diffuser, a liquid electric pluggable air freshener, an electromechanical actuating diffuser, a passive diffuser (e.g., not electrically powered) including, but not limited to a wicking air freshener, such as a reed diffuser, a steam-based freshener, or a membrane-based air freshener, such as a car vent air freshener.
As used herein, the terms “alter,” “alteration,” “altering,” “modulate,” modulation,” “modulating,” and grammatical equivalents thereof are art-recognized and refer to up-regulation (i.e., activation, stimulation, increase), or down-regulation (i.e., inhibition, suppression, reduction, or decrease) of a response, or the two in combination or apart.
As used herein, the term “aryl” means, unless otherwise stated, a polyunsaturated, aromatic, hydrocarbon substituent which can be a single ring or multiple rings (preferably from 1 to 3 rings) which are fused together or linked covalently. The term “heteroaryl” refers to aryl groups (or rings) that contain from one to four heteroatoms selected from N, O, and S, wherein the nitrogen and sulfur atoms are optionally oxidized, and the nitrogen atom(s) are optionally quaternized. A heteroaryl group can be attached to the remainder of the molecule through a carbon or heteroatom. Non-limiting examples of aryl and heteroaryl groups include phenyl, 1-naphthyl, 2-naphthyl, 4-biphenyl, 1-pyrrolyl, 2-pyrrolyl, 3-pyrrolyl, 3-pyrazolyl, 2-imidazolyl, 4-imidazolyl, pyrazinyl, 2-oxazolyl, 4-oxazolyl, 2-phenyl-4-oxazolyl, 5-oxazolyl, 3-isoxazolyl, 4-isoxazolyl, 5-isoxazolyl, 2-thiazolyl, 4-thiazolyl, 5-thiazolyl, 2-furyl, 3-furyl, 2-thienyl, 3-thienyl, 2-pyridyl, 3-pyridyl, 4-pyridyl, 2-pyrimidyl, 4-pyrimidyl, 5-benzothiazolyl, purinyl, 2-benzimidazolyl, 5-indolyl, 1-isoquinolyl, 5-isoquinolyl, 2-quinoxalinyl, 5-quinoxalinyl, 3-quinolyl, and 6-quinolyl.

Thus, the term “arylalkyl” is meant to include those radicals in which an aryl group is attached to an alkyl group (e.g., benzyl, phenethyl, pyridylmethyl and the like) including those alkyl groups in which a carbon atom (e.g., a methylene group) has been replaced by, for example, an oxygen atom (e.g., phenoxymethyl, 2-pyridyloxymethyl, 3-(1-naphthyloxy)propyl, and the like).
As used herein, the terms “connect”, “connect to,” connected to,” “attach”, “attach to” or “attached to” or grammatical equivalents thereof mean to fasten on, to fasten together, to affix to, to mount to, mount on, to connect to, to join, to position onto, to position into, to place onto, or to place into. “Attachment” means the act of attaching or the condition of being attached. Attachment can be direct or indirectly. For example, a part A may be attached directly to part B. Alternatively, part A may be attached indirectly to part B through first attaching part A to part C and then attaching part C to part B. More than one intermediary part may be used to attach part A to part B. Attaching can be permanent, temporarily, or for a prolonged time. For example, an air care product or device of the present invention may be attached to a structure, an object, an outlet, etc. temporarily for the time necessary to perform a method of the invention. Alternatively, an air care product or device of the present invention may be attached to a structure, an object, an outlet for a prolonged time, e.g., also when a method of the present invention is not performed.
As used herein, the terms “contacting,” “to contact,” “contacted to,” “contacted with,” or grammatical equivalents thereof are used interchangeably with the following: combining with, adding to, mixing with, passing over, incubating with, flowing over, etc. The term “contacting” also includes reference to placement of one substance, e.g., a freshening composition or a component of a freshening composition, as described herein, in direct physical contact or association with another component, such as a reservoir, or with another substance, such as the atmosphere, air or a surface.
As used herein, the term “different” means not the same, not the same identity.
As used herein, the terms “effective amount”, “effective dose”, “sufficient amount”, “amount effective to” or grammatical equivalents thereof mean a dosage sufficient to produce a desired result, whether permanent or temporary, lasting or transit that can be associated with the administration of a composition of the present invention. For example, certain freshening compositions of the present invention comprise a fragrance release modulator (FRM) in an amount sufficient to control or to modulate the release of the freshening composition or of a component thereof. In that example, the desired result is the controlled or modulated release of the freshening composition or of a component thereof, a result, which is attributed to the amount of FRM, expressed, e.g., as wt %, added to the freshening composition. An “effective amount,” an “effective dose,” a “sufficient amount,” or an “amount effective to” in the context of embodiments of the present invention can be determined by one of ordinary skill in the art using the disclosure of the present application, in particular, the Examples.
As used herein, the term “environment” refers to surroundings or conditions a living organism (a person, an animal, or a plant) finds themselves in or occupies. An environment includes a terrestrial environment (e.g., land, soil), an aquatic environment (e.g., marine, ocean, seas, rivers), and atmospheric environment (e.g., air) and any other spatial environment (e.g., a building, a house, a room, etc.). As used herein, an environment includes, but is not limited to, a surface of any material, e.g., a surface of a fabric, a surface of a linen, a surface of a wood, a surface of a stone, a surface of a building, a surface of a house, a surface of a room, a surface of a piece of furniture, a surface of any item that may be in a building, house or room.
As used herein, the term “fragrance release modulator,” abbreviated “FRM,” refers to a compound having the capability of modulating the release or evaporation of a freshening composition, when said fragrance release modulator is added to or combined with a perfume raw material as described herein. Release or evaporation of a freshening composition can be tested as described herein.
As used herein, the term “freshening composition” refers to a composition that comprises one or more perfume raw materials and which may be used to treat, fragrance, and/or fresh the air. A freshening composition may be used with or without an air care product, referred to herein from time to time as an air freshener device. A freshening composition can be in a liquid form.
As used herein, the terms “greater than” or “more than” include the concrete number. For example, greater than 100 or more than 100 mean greater than or equal to 100 or more than or equal to 100. As used herein, the terms “smaller than,” “fewer than.” or “less than” include the concrete number.

As used herein, the term “isomer” refers to compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers.” “Stereoisomer” and “stereoisomers” refer to compounds that exist in different stereoisomeric forms if they possess one or more asymmetric centers or a double bond with asymmetric substitution and, therefore, can be produced as individual stereoisomers or as mixtures. Stereoisomers include enantiomers and diastereomers. Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers.” When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture”. Unless otherwise indicated, the description of compounds herein is intended to include individual stereoisomers as well as mixtures. The methods for the determination of stereochemistry and the separation of stereoisomers are well known in the art (see, discussion in Chapter 4 of ADVANCED ORGANIC CHEMISTRY, 4th edition J. March, John Wiley and Sons, New York, 1992) differ in the chirality of one or more stereocenters.

Surface tension is the tendency of a fluid surface to shrink into the minimum surface area possible. Because of the relatively high attraction of water molecules to each other through hydrogen bonds, water has a higher surface tension (72.8 millinewtons per meter [mN/m] at 20° C.) than most other liquids. There are several methods available in the art to measure surface tension, including but not limited to, e.g., the Du Notly ring method, Wilhelmy plate method, spinning drop method, pendant drop method, bubble pressure method, drop volume method, capillary rise method, stalagmometric method, sessile drop method, Du Notly-Padday method, and drop-bounce method.

Dynamic viscosity (also known as absolute viscosity) is the resistance to movement of one layer of a fluid over another. It is a measure of the resistance of a fluid to deform under shear stress. It is measured with various types of viscometers (e.g., capillary or vibrating) and rheometers (e.g., rotational, or microfluidic). The SI (International System of Units) unit of a dynamic viscosity is the pascal-second (Pa-s), or equivalent kilogram per meter per second (kg*m−1*s−1). The CGS (Centimetre-gram-second system of units) unit is called the poise (P). It is commonly expressed, particularly in ASTM (American Society for Testing and Materials) standards, as centipoise (cp) since the latter is equal to the SI multiple millipascal seconds (mPA-s).

B. Fragrance Release Modulators (FRMs)
In some embodiments of the present invention, a freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, an air freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a liquid freshening composition a fragrance release modulator. In some embodiments of the present invention, a clear freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a homogenous freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a clear liquid freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a liquid air freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a homogeneous clear liquid air freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a homogeneous clear liquid air freshening composition comprises a fragrance release modulator. In some embodiments of the present invention, a non-water-based air freshening composition comprises a fragrance release modulator. Sometimes, herein a fragrance release modulator is referred to as “drop-in-fragrance release modulator” or “drop-in FRM.” It is understood and one of ordinary skill in the art will appreciate that, if not clearly contradicted by the content of this specification, each embodiment of a fragrance release modulator and/or features/elements disclosed as part of that embodiment can be combined with any of the embodiments hereinabove or hereinbelow.
When a freshening composition comprises a perfume raw material and a fragrance release modulator, those ingredients are different.
Unexpectedly and surprisingly, the inventors have found that specific combinations of a perfume raw material and solvents, diluents, or solubilizers with a fragrance release modulator (FRM), permit the customization, control, and modulation of (i) the lifespan of a freshening composition and (ii) the releasing profile of the freshening composition. This customization, control and modulation can be achieved regardless of which wicking device is used. For example, if the wicking device is a reed or a plurality of reeds, a wick or a plurality of wicks, a stick or a plurality of sticks, a fiber or a plurality of fibers, a mesh, or a combination thereof, there is no need to intervene, no need to touch the delivery device or to reverse the flow of the freshening composition through the delivery device during product usage. Moreover, at the end of product usage the reservoir in the delivery device holding the freshening composition, is substantially completely empty.
Further, and equally surprisingly and unexpectedly, the inventors have found that it will be possible to establish a two-stage functional regime and to customize, control and modulate the release of a freshening composition or of a component thereof by controlling the transport process of the freshening composition inside of, e.g., a wicking system to an emanating surface by using a “drop-in” fragrance release modulator (“FRM”). More specifically, the inventors have found that by using the “drop-in” FRM it will be possible to alter, modulate, control, and customize the surface tension, the dynamic viscosity and the density of such freshening composition. That discovery allows for the optimization, modulation, and control of the mass transport of a freshening composition through a “delivery engine,” such as a reed, a stick, a fiber, a mesh, a wick, a membrane, a porous or a semi-porous material. Thus, in some embodiments of the present invention, a fully saturated emanating surface is provided, whereby the lifespan of the air care product is optimized and controlled. Further, the strength, character, and diffusivity of the scent irrespective of the perfume raw material used, can be optimized, and controlled without altering the capability of the freshening composition to, e.g., address other functions, such as to counteract malodor ingredients or compositions or to have insect repelling activity.
Surprisingly and un-expectedly, the inventors have found that the mass transfer process of a freshening composition inside a wicking or diffusing element, as well as the mass transfer and the diffusion process of the freshening composition can be altered, modulated and controlled when specific materials, herein described as fragrance release modulators (FRM), are dropped into a perfume raw material or blend of perfume raw materials—with or without a solvent or diluent—to formulate a freshening composition. The FRM can significantly influence the wicking process inside the delivery device (further described herein), and the releasing rate of the freshening composition at the surface of the emanating device by altering the surface tension, the dynamic viscosity, the density, the flash point, and the volatility of the freshening composition. In other words, an FRM, as described herein, permits the control, the customization and the modulation of diffusivity and long-lasting characteristics of a freshening composition or of a component thereof, including, but not limited to, the perceived scent's character, the intensity and lifespan of the product. Due to the presence of an FRM, a freshening composition can be released through a two-stage process: (i) an initial transitory regime, which is associated with unusually high amount of freshening composition release, and (ii) a steady-state release regime, which implies a linear release of the freshening composition into an external environment until, or very close to its full completion (see, Examples).
As described herein, a FRM helps to formulate long-lasting air freshening products with customized releasing time, e.g., when the delivery device is a wicking or a diffusing device. There are no known formulation restrictions regarding the selection of perfume raw material, fragrance ingredients, flavor ingredients, essential oils, or functional ingredients that can be employed in combination with an FRM. Further, the inventors have not found any limitation with respect to the type of ingredient and the concentration of such ingredient when used in combination with an FRM.
By dropping the FRM into a freshening composition, which comprises a perfume raw material, the inventors surprisingly and unexpectedly have found that it is possible to control and customize (i) the surface tension of the freshening composition; (ii) the dynamic viscosity of the freshening composition; (iii) the density of the freshening composition; and (iv) the flash point of the freshening composition, all measured under normal temperature and pressure (“NTP”) conditions. This finding permits the control of the two critical steps associated with the releasing process of the freshening compositions: (i) the capillary mass transfer of the freshening composition through the “delivery element”, which can be a reed, stick, fiber, mesh, wick, semi-porous or porous materials; and (ii) the phase and mass transfer processes of the freshening composition at the emanating surface.
Freshening compositions of the present invention comprise specific amounts and compositions of FRM, depending on the desired application. FRMs generally are odorless or low-odor, non-fragrance materials, but fragrance-miscible compounds. They may be used in combination with any perfume raw material (PRM) described herein, i.e., in combination with one or more of an ester, an alcohol, an aldehyde, a ketone, an acetal, a phenol, an ether, a lactone, a furan, a hydrocarbon, an acid, a natural origin fragrance compound, a synthetic origin fragrance compound, stereoisomers, and mixtures thereof, without any restriction, and without any negative impact on the freshening competition's hedonic character and strength, as well as the freshening composition's targeting purpose.
In some embodiments of the present invention, a fragrance release modulator comprises one or more ingredients having almost no hedonic impact on a person's fragrance experience. Those ingredients permit emanating a surface to quickly saturate and to operate as a steady saturated surface during the delivery process of the freshening composition.
The inventors have found that FRMs described herein when combined with a perfume raw material to form a freshening composition bestow the desired and superior characteristics upon the freshening composition. The inventors have found the following FRMs most useful: C2-8 linear and branched alcohols, alkyl- and aryl-ethers, alkyl- and aryl-glycols, alkyl- and aryl-carbonates, alkyldiols, alkyl- and aryl-adipates, alkyl- and aryl-benzoates, alkyl- and aryl-citrates, alkyl- and aryl-laurates, alkyl- and aryl-palmitates, alkyl- and aryl-stearates, aryl-myristates, alkyl- and aryl-succinates, alkyl- and aryl-glutarates, silicon solvents, combinations and mixtures thereof.

Depending on the desirability of a user, the release of a freshening composition or of a component thereof can be up-regulated (faster) or down-regulated (slower), compared to a control not comprising an FRM.
In some embodiments of the present invention, release of a freshening composition or of a component thereof is up-regulated or accelerated, i.e., the release of the freshening composition or of a component thereof is faster than what is observed with a control (i.e., a freshening composition not comprising the FRM, but otherwise similar).
In some embodiments of the present invention, a fragrance release modulator of the present invention up-regulates the release or evaporation of a freshening composition or of a component thereof, relative to a control (not comprising said fragrance release modulator and assigned a value of 100%) by at least about 0,5%, by at least about 1%, by at least about 2%, by at least about 3% by at least about 5%, by at least about 10%, by at least about 20%, by at least about 30%, by at least about 40%, by at least about 50%, by at least about 60%, by at least about 70%, by at least about 80%, by at least about 90%, by at least about 100%, by at least about 110%, by at least about 120%, by at least about 130%, by at least about 140%, by at least about 150%, by at least about 160%, by at least about 170%, by at least about 180%, by at least about 190%, by at least about 200%, by at least about 250%, by at least about 300%, by at least about 400%, by at least about 500%, or by at least about 1,000-3,000% or more. Values for the % up-regulation are statistically significant.

Details are described in the Examples herein.
On the other hand, in some embodiments of the present invention, adding an FRM allows the user to down-regulate or slow-down the release of the freshening composition or of a component thereof.
In some embodiments of the present invention, a fragrance release modulator of the present invention down-regulates the release or evaporation of a freshening composition or of a component thereof, relative to a control (not comprising said fragrance release modulator and assigned a value of 100%) by at least about 0,5%, by at least about 1%, by at least about 2%, by at least about 3%, by at least about 5%, by at least about 10%, by at least about 15%, by at least about 20%, by at least about 25%, by at least about 30%, by at least about 35%, by at least about 40%, by at least about 45%, by at least about 50%, by at least about 55%, by at least about 60%, by at least about 65%, by at least about 70%, by at least about 75%, by at least about 80%, by at least about 85%, by at least about 90%, or by at least about 95% or more. Values for the % down-regulation are statistically significant.
A user is able to verify directly and positively such slower release (compared to a control) by, e.g., measuring the time it takes for the freshening composition or component thereof to be fully released (will be slower than the control) or weighing the freshening composition and noticing a higher weight (compared to the control) over time.

In some embodiments of the present invention, a solvent is an organic compound.
In some embodiments of the present invention, a solvent is a volatile solvent. With a few exceptions, such as silicon fluids, most high volatile solvents are classified as volatile organic compounds (VOCs). Thus, in some embodiments of the present invention, a solvent is a volatile organic compound. In the United States, acceptable levels of VOC solvents in a final product is restricted by national organizations, such as the Environmental Protection Agency (EPA) or the California Air Resources Board (CARB). The present invention provides freshening compositions that are in compliance with requirements imposed by those agencies.
The inventors have established certain key performance requirements (KPRs) for a solvent to be used for the formulation of a liquid freshening composition as described herein, preferably, for the formulation of a freshening composition for use with a wicking delivery device. According to those KPRs, a preferred solvent is completely miscible with any perfume raw material described herein. A preferred solvent is odorless, or at least of low odor. Also, according to those KPRs, a preferred solvent easily wicks through a delivery device as described herein without clogging it. Another characteristic of a solvent for use in formulating a freshening composition is to easily diffuse from the emanating surface of a delivery device into an external environment, the atmosphere, air, or onto an external surface. Other preferred characteristics of a solvent include compliance with safety requirements, such as being CARB-accepted. Further, they should be cost effective, readily available, and preferably, sustainable.
Thus, one of ordinary skill in the art knows how to characterize solvents based on their polarities, volatilities, functionalities, flash points, densities, viscosities, and surface tensions. Those basic techniques are not set forth herein.
In some embodiments of the present invention, a freshening composition comprises a solvent, a diluent, and/or a solubilizer. A solvent can also function as a diluent. A solvent may also comprise or a blend of solvents with different polarities and volatilities, a functional perfume component, such as a malodor counteracting ingredient, or combinations thereof.
In some embodiments of the present invention, a solvent is a mixture of solvents.
One of ordinary skill in the art will appreciate that a solvent or diluent for use in the present invention(s) is not limited and various solvents or diluents, not explicitly described herein, can be used to practice the present invention(s). Thus, following the Examples provided herein, a skilled artisan will be able to identify useful solvents or diluents.

Various freshening compositions were formulated. As described herein, in some embodiments, a fragrance release modulator is an aryl-ether. However, not every aryl-ether functions as a fragrance release modulator. Eucalyptol, for example, is an aryl-ether. To test whether eucalyptol functions as an FRM, the following freshening compositions, comprising two different perfume raw materials were formulated and tested: Freshening composition #1: 50 wt % linalool (a perfume raw material), 45 wt % Augeo Clean Multi® (a solvent) and 5 wt % eucalyptol (an aryl ether); Freshening composition #2: 50 wt % linalool (a perfume raw material), 50 wt % Augeo Clean Multi® (a solvent) and 0 wt % eucalyptol (an aryl ether). Freshening composition #3: 50 wt % benzyl acetate (a perfume raw material), 45 wt % Augeo Clean Multi® (a solvent) and 5 wt % eucalyptol (an aryl ether); Freshening composition #4: 50 wt % benzyl acetate (a perfume raw material), 50 wt % Augeo Clean Multi® (a solvent) and 0 wt % eucalyptol (an aryl ether). As described in Example C, 20 g of each freshening composition were added into a device and the total weight of freshening composition and device was taken at Day 0. Release of the freshening composition was determined (as described in Example C) by measuring on subsequent days the weight of the device including the remaining freshening composition in the device.
Percentage release of the freshening compositions or of a component thereof was calculated as follows: First, total weight loss was determined by subtracting the total weight at any tested subsequent days from the total starting weight on Day 0. Percentage weight loss was then determined by dividing the evaporated amount (weight loss in g) by 20 g (the starting material of the freshening composition). The following results were obtained:
Freshening Composition #1
Freshening Composition #2
One of ordinary skill in the art will appreciate that there is no statistically significant difference between the data obtained with Freshening Composition #1 (including eucalyptol) and Freshening Composition #2 (not including eucalyptol) with respect to the release of the freshening composition or of a component thereof. As such, in combination with the perfume raw material linalool and the solvent Augeo Clean Multi®, the ingredient eucalyptol does not function as a fragrance release modulator.
The data obtained with Freshening Composition #3 and Freshening Composition #4 were as follows:
Freshening Composition #3
Freshening Composition #4
One of ordinary skill in the art will appreciate that there is no statistically significant difference between the data obtained with Freshening Composition #3 (including eucalyptol) and Freshening Composition #4 (not including eucalyptol) with respect to the release of the freshening composition or of a component thereof. As such, also in combination with another perfume raw material (benzyl acetate) and the solvent Augeo Clean Multi®, the ingredient eucalyptol does not function as fragrance release modulator.
To test a higher concentration of eucalyptol in the freshening compositions of above, the concentration of eucalyptol in Freshening Compositions #1 and #3 was increased to 12.5 wt % (in the presence of 37.5 wt % Augeo Clean Multi® and 50 wt % of the same perfume raw materials). Even with a higher wt % of the ingredient eucalyptol, it did not function as a fragrance release modulator (data not shown).
