[0006] Herein, various embodiments are described to provide an overall understanding of the structure, function, manufacture, and use principles of the apparatus and methods disclosed herein. One or more examples of these embodiments are shown in the accompanying drawings. Those skilled in the art will understand that the apparatus and methods specifically described herein and shown in the accompanying drawings are non-limiting exemplary embodiments, and that the scope of the various embodiments of this disclosure is defined solely by the claims. Features shown or described in relation to one exemplary embodiment may be combined with features of other exemplary embodiments. Such modifications and variations are included within the scope of this disclosure.

[0007] A volatile composition dispenser can be used to dispense at least one volatile composition and / or other solutions or compositions, such as perfumes, fragrances, and / or insecticides, into the area surrounding the volatile composition dispenser or into the atmosphere. A volatile composition may consist of a single chemical substance or a single material that can enter the gas phase under atmospheric conditions, or more generally, a volatile composition may consist of a mixture of chemical substances and / or materials that can enter the gas phase under atmospheric conditions.

[0008] The volatile composition may include, but is not limited to, substances that can function as deodorizers, odor inhibitors, odor neutralizers, odor blockers, odor preventatives, odor masking materials, aromatherapy materials, aromacology materials, insecticides, air and / or surface cleaners, and / or combinations thereof. In various other embodiments, the volatile composition may include various other materials that can act in the gas phase to modify, enhance, and / or treat the atmosphere or area outside the volatile composition dispenser.

[0009] A volatile composition dispenser can be configured for use, for example, in the interior space or passenger compartment of a vehicle, but the present invention is not limited to such use. Although a volatile composition dispenser is described herein in relation to use in a vehicle, those skilled in the art will understand that the dispenser can be configured for use in any environment, such as a home or office, or can even be worn by a person and configured to dispense any suitable solution, chemical, material, and / or composition.

[0010] A volatile composition dispenser may be configured as a non-electric volatile composition dispenser for the continuous delivery of a volatile composition. "Non-electric" may mean that the device is passive and does not need to be powered by an external energy source. The volatile composition dispenser does not need to be powered by a heat source, gas source, or current source, and the volatile composition is generally not delivered by aerosol means.

[0011] The continuous emission of at least one volatile composition may be for any suitable length, such as up to 20, 30, 40, 60, or 90 days, shorter or longer, or any period between 10 and 90 days. Naturally, the volatile composition dispenser may contain more or fewer volatile compositions to increase or decrease its effective lifespan. Furthermore, the effective lifespan of the volatile composition dispenser may depend on the operating conditions (i.e., temperature, pressure, moisture content, etc.).

[0012] When a volatile composition dispenser is configured for use in an automobile, it may be positionable on a vent in the vehicle's air treatment system. The vent may, for example, comprise a plurality of louvers and a louver adjustment mechanism. The volatile composition dispenser can be mounted on the vent, for example, by engaging the dispenser mounting portion with the louvers. In such embodiments, air pushed out or blown out of the vent by the air treatment system flows through the volatile composition dispenser, allowing any evaporated (i.e., gaseous) volatile composition to be deployed from the volatile composition dispenser into the interior space or passenger compartment of the vehicle. Such deployment of the volatile composition can, as described above, for example, treat the air in the passenger compartment or interior space of the vehicle.

[0013] Referring to Figures 1 to 9, the volatile composition dispenser 10 includes a housing 12 defining a longitudinal axis LA. The housing 12 has at least a base 14 and an upper part 16 that is rotatably and releasably connected to the base 14. When the base 14 and the upper part 16 are connected, they combine to define the interior 18 and exterior 20 of the housing 12. The interior 18 of the housing 12 is configured to at least partially surround and house a volatile composition cartridge 22. The volatile composition cartridge 22 contains a volatile composition. The housing 12 may be reused when the volatile composition cartridge is depleted. When the volatile composition is depleted or nearly depleted from the volatile composition cartridge 22, the base 14 and the upper part 16 can be separated, and a new volatile composition cartridge 22 can be inserted into the housing 12. More specifically, the upper part and / or base may be rotatably and releasably connected to each other around the longitudinal axis LA.

[0014] Referring to Figures 3 and 4, the base 14 defines the first surface 24 and the opposing second surface 26. The side wall 28 is positioned between the first surface 24 and the second surface 26 and surrounds at least a portion of the first surface 24 and the second surface 26.

[0015] Referring to Figures 5 to 7, the upper part 16 defines a first surface 30 and an opposing second surface 32. The side wall 34 is positioned between the first surface 30 and the second surface 32 of the upper part 16 and surrounds at least a portion of the first surface 30 and the second surface 32. The side wall 34 defines an internal side wall 44 and an external side wall 46. The upper part 16 may include an opening 17 for exposing a portion of the volatile composition cartridge or for allowing the volatile composition cartridge to be viewed from the outside.

[0016] The housing includes at least one guide projection 36 and at least one concave track 38. The guide projection 36 is located on either the base 14 or the upper 16 of the housing. The concave track 38 is located on either the base 14 or the upper 16. If the guide projection 36 is located on the base 14, the concave track 38 is located on the upper 16. Similarly, if the guide projection 36 is located on the upper 16, the concave track 38 is located on the base 14. The concave track 38 is configured to receive and guide the guide projection 36 when the base 14 and the upper 16 rotate relative to each other to connect or separate them.

[0017] Figures 2 to 4 show a non-limiting exemplary configuration in which at least one guide projection 36 is located on the side wall 24 of the base 14. Referring to Figure 7, at least one concave track 38 is located on the inner side wall 44 of the upper part 16.

[0018] Figures 8 and 9 show a non-limiting exemplary configuration in which the side wall 28 of the base 14 defines the inner side wall 48 and the outer side wall 50. At least one guide projection may be located on the inner side wall 44 of the upper part 16, and the concave track 38 may be located on the outer side wall 50 of the base 14.

[0019] Referring to Figures 6 to 9, the concave track 38 includes a track opening 40 and a track stop 42. To connect the base 14 and upper 16 of the housing 12, the user can first align the guide projection 36 with the track opening 40, and then rotate one or both of the base 14 and upper 16 relative to each other so that the guide projection 36 moves circumferentially through the concave track 38. As the guide projection 36 moves through the concave track 38, the base 14 and upper 16 are brought closer to each other. The user rotates one or both of the first and second parts until the guide projection 36 reaches the track stop 42. Reaching the track stop 42 indicates to the user that the first and second parts of the housing 12 are fully connected.

[0020] Referring to Figures 6 to 8, the concave track 38 may include an axial outermost point 43 located between the opening and the track stop. The axial outermost point 43 may be adjacent to the track opening 40, or at least relatively closer to the track stop 42 than to the track opening 40. When the guide projection 36 is positioned at the axial outermost point 43, the first surface 24 of the base 14 is closer to the second surface 32 of the upper part 16 than to any other position of the guide projection 36 on the concave track 38. When the guide projection 36 is positioned at the track stop 42, the first surface 24 of the base 14 and the second surface 32 of the upper part 16 are further apart in the axial direction than when the guide projection 36 is positioned at the axial outermost point 43.

[0021] If the housing 12 includes two or more concave tracks 38 and guide projections 36, the concave tracks have substantially the same curved shape so that the guide projections 36 move simultaneously through the concave tracks 38 and at the same relative position on the concave tracks 38.

[0022] The guide projection 36 may have various shapes. For example, the guide projection 36 may be circular, elliptical, round, square, rectangular, triangular, or the like.

[0023] The concave track 38 may have a curved shape. The concave track 38 may have a relatively uniform width sized to accommodate the guide projection 36. The width of the concave track 38 may be slightly larger than the guide projection 36.

[0024] As shown in Figures 10 and 11 for illustrative and non-limiting purposes only, the recessed track 38 may include a narrow-width limiting section 52 adjacent to the track stop 42 to cause an interference fit for the guide projection 36 at the track stop 42. The limiting section 52 may help prevent the upper section 16 from prematurely separating from the base section 14 during normal use of the distributor 10. The limiting section 52 may also produce a “click” or similar sound when the user rotates the guide projection 36 through the limiting section 52. The limiting section 52 should be narrow enough to limit the upper section 16 and base section 14 from prematurely separating, but should not be too narrow to prevent the user from guiding the guide projection 36 through the limiting section during either assembly or disassembly of the housing 12. Although the limiting section 52 is shown on the upper section 16, it should be understood that if the recessed track 38 is located on the base section 14, the recessed track 38 may also include the limiting section 52.

[0025] Referring to Figures 1 and 2, the volatile composition dispenser 10 may include a mounting portion 54. The mounting portion 54 may be connected to the base 14 of the housing 12. The mounting portion 54 may be bonded to a second surface 26 of the base 14. The mounting portion 54 may be used to mount the volatile composition dispenser 10 to an object, for example, a vent in a vehicle's air system. Thus, the mounting portion 54 may include one or more retaining elements 56 configured to engage with a portion of the object to which it is mounted. Naturally, the mounting portion 54 may also include any other suitable gripping or engaging mechanism that enables the volatile composition dispenser 10 to be mounted to another object or a vent in an air system.

[0026] Referring to Figures 1 and 2, the base 14 and / or upper 16 of the housing 12 may include one or more airflow openings 58. The airflow openings 58 facilitate airflow inside the housing 12. The airflow openings 58 may facilitate airflow throughout the volatile composition cartridge, thereby increasing the volatilization of the volatile composition from the volatile composition cartridge. Air can flow inside the housing 12 by natural convection. By mounting the volatile composition dispenser 10 to a vent (i.e., a car vent or a household HVAC vent) via the mounting portion, an increase in airflow through the housing 12 can be facilitated.

[0027] The housing may include one or more actuators 60. Referring to Figure 3, the actuators 60 may be positioned on the base 14. As will be described in more detail below, the actuators 60 may "activate" or release volatile compositions. The actuators 60 may be positioned on the surface of the base 14 facing the mounting portion (if any). The actuators 60 may protrude from the first surface 24 of the base 14. The actuators may have a variety of shapes. For example, the actuators may have an arched or rounded shape. Two or more actuators may be used to cause a more uniform pressure distribution across the moving members of the bursting mechanism.

[0028] Referring to Figures 12 and 13, the volatile composition dispenser 10 may include an airflow adjustment mechanism 66 positioned above at least one airflow opening. The airflow adjustment mechanism 66 may be connected to or formed together with a first or second portion of the housing 12. The airflow adjustment mechanism 66 may be configured to move between at least a first position and a second position to at least partially or completely cover at least one of the airflow openings. The airflow adjustment mechanism 66 may be configured to move between a first position, as shown in Figure 12, which at least partially covers all of the airflow openings on the housing 12, and a second position, as shown in Figure 13, which does not cover all of the airflow openings.

[0029] By providing an airflow adjustment mechanism, the user can adjust the airflow rate through the volatile composition dispenser 10, thereby adjusting the amount of evaporated volatile composition distributed to the surrounding atmosphere by the volatile composition dispenser 10. This feature gives the user the ability to essentially "customize" the volatile composition dispenser 10 to various personal preferences. If the entire airflow opening is not covered, more air flows through the volatile composition dispenser 10, thereby providing more fragrance, odor treatment, etc., to the atmosphere surrounding the volatile composition dispenser 10. If at least a portion of the airflow opening is covered, less air flows through the dispenser, thereby potentially providing less fragrance, odor treatment, etc., to the atmosphere surrounding the volatile composition dispenser 10.

[0030] Referring to Figures 14 and 15, the volatile composition dispenser 10 may include a cover 62 that is removably connected to the housing 12. The cover may be an aesthetically pleasing decorative cover for the user. The cover may be made up of various three-dimensional designs. The cover may be interchangeable with the housing 12 so that the user can customize the volatile composition dispenser 10 to their individual aesthetic preferences. The cover 62 may be connected to the upper part 14 and / or the base part 12. The cover 62 may be configured to conceal all or part of the base part and / or the upper part 14. The cover 62 may include a window 64 configured to display the volatile composition cartridge 22. The window may be made up of various different shapes, including, for example, circular, elliptical, rectangular, square, etc. The window 64 of the cover 62 may be the same or similar in shape to the opening 17 of the upper part 16. The cover 64 may also include one or more airflow openings 68. The cover 62 may be a separate component that can be releasably connected to the housing 12, or a separate component that is permanently attached to the upper part 16 of the housing 12, or the cover 62 may be formed integrally with the upper part 16 of the housing 12.

[0031] Volatile composition cartridges can be configured in various ways. A volatile composition cartridge may contain a liquid volatile composition that evaporates through a film. A volatile composition cartridge may also be in the form of a solid or semi-solid gel or wax.

[0032] Referring to Figures 16 to 22, the volatile composition cartridge 22 may include a container 72 having an orifice 74 in which the volatile composition 70 is stored. A burstable substrate 76 covers the orifice 74, sealably mounted to the orifice 74 defining the reservoir to prevent the volatile composition 70 from being released until the volatile composition dispenser 10 is activated. By activating a bursting mechanism 80 positioned adjacent to the burstable substrate 76, the burstable substrate 76 can burst and release the volatile composition 70. The bursting mechanism 80 includes a movable member 82 movably mounted to an outer frame 84 by an elastic member 86. The elastic member 86 may be formed of one or more springs. One or more bursting elements 90 are positioned within the bursting mechanism 80 to puncture the burstable substrate 76. The bursting elements 90 may reach a point 91 to assist in the bursting of the burstable substrate 76. The volatile composition cartridge 22 may include a membrane 92 positioned outside the volatile composition cartridge 22. The membrane 92 may be sealed to a flange 94 positioned on the outer edge 96 of the container 72. The membrane 92 encloses the container 72, the volatile composition 70, the burstable substrate 76, and the bursting mechanism 80. The membrane 92 may be configured to flex when pressure or activating force is applied to the membrane 92.

[0033] Referring to Figures 18 to 22, the bursting elements 90 are spaced apart on the movable member 82. The position of the bursting elements 90 is configured to puncture a hole on one side of the burstable substrate 76 to allow air to enter the container 72, and to puncture another hole on the opposite side to discharge the volatile composition from the container 72, thereby creating a pressure difference between the inside and outside of the container. This pressure difference allows the volatile composition to be discharged from one of the holes located at the bottom end of the burstable substrate 76 as air enters the container 72 through the other hole at the top end of the burstable substrate 76.

[0034] The internal components of the volatile composition cartridge 22 shown in Figures 16 to 22 can be characterized as follows. For example, the dimensions of the container 72 may be configured to hold about 1 ml to about 50 ml of liquid volatile composition. Alternatively, the reservoir can hold about 2 ml to about 30 ml, alternatively about 2 ml to about 10 ml, alternatively about 2 ml to about 8 ml, alternatively about 4 ml to about 6 ml, alternatively about 2 ml, and alternatively about 6 ml of liquid volatile composition. Furthermore, the shape of the container 72 may be configured to correspond to the shape of the top opening 17. For example, the container 72 can be substantially defined as a circle, ellipse, or oblong shape, and its width-to-length ratio can be about 1:2 to 1:2.5.

[0035] The burstable substrate 76 can be made from any material that bursts upon applied force, whether or not elements that aid in such bursting are present. Since the burstable substrate 76 is intended to contain volatile materials during storage, it can be made from any barrier material that prevents the evaporation of volatile materials before its intended use. Such materials can be impermeable to vapors and liquids. Suitable barrier materials for the burstable substrate 76 include flexible films such as polymer films, flexible foils, or composite materials such as foil / polymer film laminates. Suitable flexible foils include metallic foils such as foil composed of nitrocellulose protective lacquer, 20-micron aluminum foil, polyurethane primer, and a 15 g / m2 polyethylene coating agent (Lidfoil 118-0092) available from Alcan Packaging. Suitable polymer films include polyethylene terephthalate (PET) films, acrylonitrile copolymer barrier films (such as those sold by INOES under the trademark name Barex®), ethylene vinyl alcohol, and combinations thereof. The coated barrier films may also be used as burstable substrates 76. Such coated barrier films that may be used include metallized PET, metallized polypropylene, silica, or alumina-coated films. Any of these barrier materials, coated or uncoated, may be used alone and / or in combination with other barrier materials.

[0036] The bursting mechanism 80 can be manufactured by injection molding, compression molding, or pressure molding using polyethylene or polyolefin such as polypropylene, polyester, or other plastics known to be suitable for molding. The bursting mechanism 80 may also be manufactured by thermoforming, with a separate cutting step for removing undesirable portions.

[0037] The membrane 92 may be a microporous membrane with an average pore diameter of about 0.01 to about 0.06 microns, alternatively about 0.01 to about 0.05 microns, alternatively about 0.01 to about 0.04 microns, alternatively about 0.01 to about 0.03 microns, alternatively about 0.02 to about 0.04 microns, alternatively about 0.02 microns. Further, the membrane 92 may be filled with any suitable filler and plasticizer well-known in the technical field. Examples of the filler include micronized silica, clay, zeolite, carbonate, activated carbon, and mixtures thereof. The microporous membrane 92 may be filled with silica at about 50% to about 80%, alternatively about 60% to about 80%, alternatively about 70% to about 80%, alternatively about 70% to about 75% based on the total weight. The thickness of the membrane 92 may be about 0.01 mm to about 1 mm, alternatively about 0.1 mm to about 0.4 mm, alternatively about 0.15 mm to about 0.35 mm, alternatively about 0.25 mm.

[0038] Furthermore, the evaporation surface area of the microporous membrane 92 is about 2 cm 2 to about 100 cm 2 , alternatively about 2 cm 2 to about 25 cm 2 , alternatively about 10 cm 2 to about 50 cm 2 , alternatively about 10 cm 2 to about 45 cm 2 , alternatively about 10 cm 2 to about 35 cm 2 , alternatively about 15 cm 2 to about 40 cm 2 , alternatively about 15 cm 2 to about 35 cm 2 , alternatively about 20 cm 2 to about 35 cm 2 , alternatively about 30 cm 2 to about 35 cm 2 , alternatively about 35 cm 2 and may be. Therefore, the rear frame 200 can be sized and shaped to fit the evaporation surface area of the membrane 92.

[0039] Suitable microporous membranes of the present invention include microporous, ultra-high molecular weight polyethylene (UHMWPE), optionally filled with silica, as described in U.S. Patent No. 7,498,369. Examples of such UHMWPE microporous membranes include Daramic® V5, available from Daramic; Solupor®, available from DSM (Netherlands); Teslin®, available from PPG Industries; combinations thereof; and membranes available from Microporous LLC.

[0040] Referring to Figures 17, 20-21, and 23-25, if the volatile composition cartridge 22 has a burstable substrate 76, the actuator 60 on the base 14 can be used to burst the burstable substrate 76 and release the volatile composition 70 onto the membrane 92. The concave track 38 is shaped so that a guide projection 36 moves through the concave track 38 when the user rotates the base 12 and / or upper 14 together. When the guide projection 36 reaches the outermost axial point 43 on the concave track 38, the actuator 60 contacts the membrane 92 and applies pressure, and the membrane 92 then applies pressure to the movable member 82 of the bursting mechanism 80. This pressure applied to the movable member 82 bends the elastic member 86, bringing the bursting element 90 into contact with the burstable substrate, and the bursting element 90 perforates the burstable substrate 76, thereby forming a hole in the burstable substrate as shown in Figure 21. When a puncture is formed in the burstable substrate 76, the volatile composition is released, the liquid is absorbed into the membrane, and ultimately released into the environment through long-term evaporation. When this pressure on the burstable substrate 76 results in puncture formation, the user rotates the guide projection 36 continuously through the concave track 38 to the track stop 42, causing the actuator 60 to shift so that it does not come into contact with the membrane 92 and apply pressure to it. When the pressure applied to the membrane 92 by the actuator 60 is removed, the elastic member 86 bends back to a non-pressurized state, as shown in Figure 20, thereby moving the bursting element 90 away from the burstable substrate 76. This backward movement of the bursting element 90 allows the puncture to remain unobstructed, allowing the volatile composition to flow more easily from the container to the membrane 92.

[0041] When the volatile composition in the volatile composition cartridge 22 is depleted, the user can separate the base 14 and the upper part 16 by rotating them so that they are separated from each other, as shown in Figure 25.

[0042] Suitable volatile materials or compositions for use in the volatile composition cartridge 22 for the volatile composition dispenser 10 may be configured to regulate, modify, or otherwise alter the state of the atmosphere and may include compositions suitable for providing fragrances, deodorizers, odor removers, odor suppressants, odor inhibitors, insecticides, insect repellents, medicinal substances, disinfectants, cleaning agents, mood enhancers, and aromatherapy aids. A list of suitable volatile materials is shown in Table 2 below.

[0043] [Table 1]

[0044] The composition may be formulated to include a mixture of volatile materials, each comprising about 10% to about 100% of the total weight of a volatile material having a VP of less than about 0.01 torr at 25°C, alternatively, about 40% to about 100% of the total weight of a volatile material having a VP of less than about 0.1 torr at 25°C, alternatively, about 50% to about 100% of the total weight of a volatile material having a VP of less than about 0.1 torr at 25°C, or alternatively, about 90% to about 100% of the total weight of a volatile material having a VP of less than about 0.3 torr at 25°C. A mixture of volatile materials may contain 0% to about 15% of the total weight of volatile materials, each with a VP of about 0.004 torr to about 0.035 torr at 25°C; 0% to about 25% of the total weight of volatile materials, each with a VP of about 0.1 torr to about 0.325 torr at 25°C; and about 65% to about 100% of the total weight of volatile materials, each with a VP of about 0.035 torr to about 0.1 torr at 25°C. One source of information for obtaining the saturated vapor pressure of volatile materials is the EPI Suite®, version 4.0, available from the U.S. Environmental Protection Agency.

[0045] Referring to Figure 26, the volatile composition cartridge 22 may be in the form of a solid gel article 108. The solid article may be molded from a moldable material such as one of the gel compositions described below.

[0046] The gel may be a chemically crosslinked polyol or a derivative thereof. Suitable polyols or derivatives can be selected from the group consisting of polyols, polyester polyols, polyglycerols, and mixtures thereof. Polyols, polyester polyols, and polyglycerols contain multiple hydroxyl groups and are suitable for forming gels with a compact network. In addition, the resulting gel has a higher affinity for less hydrophobic materials.

[0047] Suitable polyols or their derivatives may have molecular weights of 60 Da to 10,000 Da, preferably 150 Da to 3,000 Da, more preferably 500 Da to 2,000 Da, and even more preferably 600 Da to 1,300 Da. Longer polyols and their derivatives result in higher flexibility of the gel.

[0048] Suitable polyols and their derivatives do not contain terminal hydroxyl groups. Secondary alcohols are particularly preferred. Primary alcohols with terminal hydroxyl groups typically result in more linear and more compact networks. Combinations of primary and secondary alcohols are preferred to yield a more desirable correlation length.

[0049] An average correlation length of less than 8 nm is preferred when measured using small-angle X-ray scattering (SAXS). However, the gel compositions described herein can be formulated to have any desired correlation length.

[0050] When secondary alcohols are used, gels with more optimal pore sizes can be obtained. Lightly branched polyols and their derivatives, such as poly(diethylene glycol adipate), result in more flexible gels. Preferred polyols and their derivatives have at least two hydroxyl groups per molecule, more preferably at least three hydroxyl groups per molecule.

[0051] Polyols are compounds containing multiple hydroxyl groups. Diol polyols with two hydroxyl functional groups result from crosslinking in linear polymers or in more open networks with larger pore sizes. In contrast, hydroxyl-functional monomers with more than two functional groups form more compact gels with smaller pore sizes. Suitable polyols include ethylene glycol, propylene glycol, 1,4-butanediol, 1,6-hexanediol, pentaerythritol, 1,2,6-hexanetriol, 4,6-di-tert-butylbenzene-1,2,3-triol, propanetriol (glycerol), 1,2,5-hexanetriol, 1,2,4-cyclohexanetriol, 2,5-dimethylhexane-1,2,6-triol, 3-hydroxymethylpentane-1,2,5-triol, 1,3,6-hexanetriol, 1,1,5,5-pentanetretraol, 1,2,5,6-hexanetretraol, 1,2,3,4,5,6-hexanehexol (sorbitol), and mixtures thereof.

[0052] Polyester polyols are hydroxyl-containing esters. Suitable polyester polyols can be selected from the group consisting of aliphatic polyester polyols, aromatic polyester polyols, organic oil-based polyester polyols, and mixtures thereof. Organic oil-based polyester polyols are preferred. Preferred organic oils are vegetable oils, as they typically contain a high concentration of unsaturated (C=C) bonds and naturally contain hydroxyl groups. Suitable polyester polyols include hexanoic acid, 4-hydroxy-,1,1',1''-(1,2,3-propanetriyl) ester; pentanoic acid, 5-amino-4-hydroxy-,1,1',1''-(1,2,3-propanetriyl) ester; polycaprolactone triols; castor oil, hydroxyl sunflower oil (HSO), and mixtures thereof.

[0053] Castor oil is particularly suitable. Castor oil (Ricinus communis) is a pale yellow, viscous liquid extracted from the beans (Ricinus communis) of the castor plant. Castor oil is mainly composed of fatty acid triglycerides containing 87-90% ricinoleic acid (cis-12-hydroxyoctadeca-9-enoic acid) and can be obtained in high purity grades. Castor oil and its derivatives have been used as polyols for polyurethanes and adhesives. Castor oil can be partially hydrogenated. Castor oil has been found to be particularly suitable for providing chemically crosslinked gels with pore sizes that result in the slow release of hydrophobic materials, especially when the hydrophobic material is a fragrance. In addition, chemically crosslinked gels derived from castor oil show less extrusion of hydrophobic material from the gel.

[0054] Polyglycerols are hydroxyl-containing ethers. Polyglycerols are typically obtained by polymerization of alkylene oxides (such as epoxides). Suitable alkylene oxides include ethylene oxide, propylene oxide, butylene oxide, and mixtures thereof, using chain initiators such as ethylene glycol, propylene glycol, diethylene glycol, dipropylene glycol, 1,4-butanediol, neopentyl glycol, pentaerythritol, hexanetriol, sorbitol, glycerol, and mixtures thereof. Suitable polyglycerols can be selected from the group consisting of α,α-diglycerol, α,β-diglycerol, hyperbranched polyglycerol, dendritic polyglycerol, and mixtures thereof. Hyperbranched polyglycerols are aliphatic polyethers having multiple hydroxyl-terminated groups, obtained from the asymmetric polyaddition of glycidol to glycerol, resulting in a spherical, branched structure that provides special internal flexibility. Dendritic polyglycerols are hyperbranched polyglycerols having a clearly defined, symmetrical, spherical three-dimensional structure around a core. Apart from improved gel elasticity, the dendritic structure of hyperbranched polyglycerols, with their exceptionally numerous functional groups and sterically shielded core, produces flexible gels with relatively small pore sizes. This increases the lifetime of the final composition by reducing the diffusion rate as a result of improved H-bonding and van der Waals interactions, in addition to physically encapsulating the hydrophobic material. Such polyglycerols can be purchased from Nanopartica GmbH (Germany) and Sigma-Aldrich. Suitable polyglycerols include polyethylene glycol, polypropylene glycol, poly(diethylene glycol), poly(dipropylene glycol), poly(1,4-butanediol), poly(neopentyl glycol), poly(1,6-hexanediol), and mixtures thereof. The polyglycerols preferably have 2 to 50, preferably 4 to 30, repeating units.

[0055] Any suitable crosslinking agent may be used, but a crosslinking agent selected from the group consisting of isocyanates, isothiocyanates, and mixtures thereof is preferred. The crosslinking agent may be linear, branched, or cyclic isocyanates, and mixtures thereof. Cyclic isocyanates and mixtures thereof are preferred. Suitable cyclic isocyanates include heterocyclic isocyanates such as 1,3,5-tris(5-isocyanatopentyl)-1,3,5-triazine-2,4,6(1H,3H,5H)-trione.

[0056] Suitable crosslinking agents include 1,4-butane diisocyanate (BDI), 1,6-hexamethylene diisocyanate (HMDI), L-lysine ethyl ester diisocyanate (LDI), 4,4'-methylenebis(cyclohexyl isocyanate) (H12MDI), glycolide-ethylene glycol-glycolide isocyanate (Bezwada, LLC), 4,4'-methylenebis(phenyl isocyanate) (MDI), 2,4'-methylenebis(phenyl isocyanate) (MDI), 2,2'-methylenebis(phenyl isocyanate) (MDI), isophorone diisocyanate (IPDI), and 2,4-toluene diisocyanate (2,4-TDI). The crosslinking agents can be selected from the group consisting of 2,6-toluene diisocyanate (2,6-TDI), poly(hexamethylene diisocyanate) (PDI), 1,3-bis(2-isocyanatopropan-2-yl)benzene, poly(pentamethylene diisocyanate), and mixtures thereof, preferably 1,6-hexamethylene diisocyanate (HMDI), L-lysine ethyl ester diisocyanate (LDI), poly(pentamethylene diisocyanate), poly(hexamethylene diisocyanate) (PDI), 1,3,5-tris(5-isocyanatopentyl)-1,3,5-triazine-2,4,6(1H,3H,5H)-trione, and mixtures thereof. Such crosslinking agents are available from Sigma-Aldrich and Covestro under the trademark name Desmodur® eco N7300.

[0057] The crosslinking agent may have a viscosity of less than 2,500 mPa·s at 25°C and an isocyanate equivalent of 15% to 40%, preferably 18% to 30%. Such crosslinking agents blend more readily with polyols. As a result, a more uniform gel can be obtained.

[0058] The gel can be formed using a molar ratio of polyol (or its derivative) to crosslinking agent of 1:0.75 to 1:2, preferably 1:0.8 to 1:1.6, and more preferably 1:0.8 to 1:1.2. These ratios of polyol to crosslinking agent typically result in a gel with a viscosity coefficient G'' and an elastic modulus G' of the same order of magnitude. In addition, the ratio of polyol to crosslinking agent typically results in a gel with an elastic modulus G' greater than 0.1 kPa, preferably greater than 1 kPa, more preferably greater than 2 kPa, and less than 100 kPa.

[0059] The gel preferably contains essentially no unreacted isocyanates and / or isothiocyanates.
