Description

[Technical Field]

[0001] FIELD OF THE INVENTION The present invention relates generally to freshening compositions and methods for freshening the air or surfaces of an interior environment. [Background technology]

[0002] In the interior environment, it is known that regular cleaning and frequent disinfection of high-touch objects and high-touch surfaces prevents bacterial growth on the objects or surfaces and prevents bacterial infection. High-touch objects and / or surfaces can be anything that is frequently touched, for example, sofas, beds, frequently used items, and kitchen and bathroom surfaces such as trash cans, toilets, wallpaper, bathtubs, and floors.

[0003] Antibacterial cleaning compositions containing materials with disinfecting or cleaning functions have been used to reduce or eliminate microorganisms, such as bacteria, present on surfaces. For example, typical disinfecting materials used in antibacterial compositions may contain, for example, peracids and / or halogen-releasing compounds, such as hypochlorite. A drawback associated with such antibacterial cleaning compositions is that the odor from such disinfecting materials may be perceived as unpleasant by consumers. While fragrances are sometimes incorporated into antibacterial cleaning compositions to mask the odor of the disinfecting materials, such compositions generally do not provide a "balanced" scent that includes high, medium, and base scent "notes." Despite the addition of fragrances, the odor from the disinfecting materials may linger or become particularly strong after cleaning.

[0004] Furthermore, toilet odors continue to emanate from the use of the toilet bowl, which is used to contain fecal waste excreted by humans, even after flushing. Fecal waste contains bacteria, which are the primary source of odors in toilets (the source that actually produces the odors). When the toilet bowl is flushed, bacterial particles spread rapidly above and around the interior area of ​​the toilet and tend to settle on various surfaces within the toilet (including, but not limited to, permeable materials such as terry towels, vinyl floor mats, and wallpaper). Such surfaces containing bacterial particles become secondary sources of odors. The use of conventional air fresheners to spray fragrances in the immediate area of ​​the toilet has been quite effective in masking the odors resulting from the primary odor sources described above. Furthermore, toilet bowl cleaner dispensers have been developed to clean and freshen toilet bowls after use. One type of dispenser for spraying cleaning and / or deodorizing chemicals onto the interior surfaces of a toilet bowl is described in U.S. Patent No. 7,603,726(B2) (Assigned to SC Johnson & Son, Inc.) However, as described in U.S. Patent No. 7,603,726(B2), while the dispenser functions by incorporating active substances into the toilet water to create a cleaning environment within the toilet bowl, it does not necessarily help prevent bacterial growth in secondary sources of malodor outside the toilet bowl.

[0006] Therefore, there is a need to provide a freshening composition that can be used to freshen the air or surfaces in an interior environment and that provides a balanced fragrance while preventing bacterial growth on surfaces in the interior environment (thereby preventing bacterial malodor). [Means for solving the problem]

[0007] The present invention provides a freshening composition for freshening the air or surfaces of an interior environment, comprising: (i) a C5-C8 unsubstituted linear alkenal; (ii) C9-C14 unsubstituted linear alkenal; (iii) Formula (I),

[0008] [ka] [In the formula, R1 is an alkoxyl group or a hydroxyl group; R2 is an alkyl group or hydrogen; R3 is hydrogen; R4 is hydrogen; R5 is an alkyl group or hydrogen; R6 is hydrogen or an alkyl group; and phenolic derivatives of terpenes according to the formula: when R5 is an alkyl group, R6 is hydrogen, and when R5 is hydrogen, R6 is an alkyl group; the total amount of (i), (ii), and (iii) is 0.05% to 20% by weight of the composition; The present invention relates to a freshening composition, wherein the composition is substantially free of anionic surfactants. DETAILED DESCRIPTION OF THE INVENTION

[0009] The present invention relates to freshening compositions for freshening the air or surfaces in an interior environment and providing a balanced fragrance while preventing bacterial growth on surfaces in the interior environment (thereby preventing bacterial malodor).

[0010] It has been found that cleaning compositions and materials constituting and / or contained within enclosed spaces play an important role in the presence of odors in the air. Specifically, malodor-containing compounds in cleaning compositions, such as bacteria, amines, thiols, and odorous antimicrobial active agents, are often absorbed by certain substances, such as permeable materials, and re-evolatilized into the air, causing lingering malodors during periods when malodors are not otherwise being produced. It has also been surprisingly found that a freshening composition substantially free of anionic surfactants and comprising a C5-C8 unsubstituted linear alkenal, a C9-C14 unsubstituted linear alkenal, and a phenolic derivative of a terpene, when formulated at a concentration of 0.05% to 20% by weight in a freshening composition according to the present invention, can be applied to surfaces, including permeable materials, where the freshening composition continuously evaporates under passive airflow conditions to deposit the malodor-containing compounds thereon. The adhesive mixture of C5-C8 unsubstituted linear alkenals, C9-C14 unsubstituted linear alkenals, and phenolic derivatives of terpenes can adsorb to surfaces bearing permeable materials to freshen the surfaces and help prevent bacterial growth on the permeable materials.

[0011] The phenolic derivatives of terpenes are represented by the formula (I):

[0012] [ka] [In the formula, R1 is an alkoxyl group or a hydroxyl group; R2 is an alkyl group or hydrogen; R3 is hydrogen; R4 is hydrogen; R5 is an alkyl group or hydrogen; R6 is hydrogen or an alkyl group; When R5 is an alkyl group, R6 is hydrogen, and when R5 is hydrogen, R6 is an alkyl group.

[0013] By providing a mixture of a phenolic derivative of terpene and two different types of alkenals in an amount of 0.05% to 20% by weight of the freshening composition, it is possible to deliver the desired fragrance notes while providing the benefit of antimicrobial effects on surfaces in the interior environment, thereby freshening the air in the interior environment.

[0014] Providing the mixture in a freshening composition to provide the benefit of secondary antibacterial effect is advantageous because the mixture is compatible with other perfume raw materials that are generally used to provide comfort effects. Specifically, the phenolic derivative of terpene according to formula (I) is compatible with two different types of alkenals, and can achieve the dual effects of providing bacterial growth prevention effect on target surfaces while reducing malodor on the target surfaces, thereby freshening the surfaces and / or air of the interior environment. The interior environment may include a surface having a permeable material selected from the group consisting of fabric, drywall, woven fabric, paper, natural polymers, synthetic polymers, and inorganic materials, and mixtures thereof; preferably, the permeable material is selected from the group consisting of terry towel, cotton, vinyl, and combinations thereof.

[0015] In the following description, the products described are consumer products, such as toilet deodorizers, that vaporize a freshening composition in an interior bathroom occupancy, including a toilet, to provide various benefits, such as preventing bacterial growth, freshening, eliminating malodors, or fragrance the air in the bathroom. However, it is contemplated that the products may be configured for use in a variety of applications to deliver the freshening composition to benefit interior environments, such as rooms or household storage furniture in homes and commercial establishments, and air freshening products may include, but are not limited to, consumer products such as air fresheners, air fresheners, and fabric freshening products.

[0016] The product may also include a delivery member configured to contain the liquid-phase composition and evaporate the liquid-phase freshening composition therefrom. Delivery members may include porous or semi-porous substrates, including wicks, membranes, gels, and felt pads. An exemplary delivery member may be a membrane, which is a semi-permeable material that allows certain components of a substance to pass through while blocking others. For components that pass through the membrane, the membrane regulates the permeability of the component (i.e., allows certain components to pass through more quickly than others). Such components may include molecules, ions, or particles.

[0017] Prior to describing the present invention in detail, the following terms are defined for clarity of description. Terms not defined should be given their ordinary meaning as understood by one of ordinary skill in the relevant art.

[0018] An "internal environment" refers to a finite volume of space in a built environment. An internal environment can be a room in a vehicle, residential, or commercial environment, such as a sanitary facility. Sanitary facilities can include bathrooms, including bathrooms, toilets, and restrooms, and locker rooms. Internal environments can also be enclosed spaces, such as furniture for storing personal items, including, but not limited to, shoe cabinets, wardrobes, and gym lockers, as well as litter boxes, cat litter boxes, pet cages, and pet carriers. A pet carrier is a small, portable box, crate, or cage used to transport small animals, such as cats, small dogs, hamsters, and guinea pigs, from one location to another.

[0019] As used herein, "membrane" refers to a semipermeable material that allows certain components of a substance to pass through while blocking others. For components that pass through the membrane, the membrane regulates the permeability of the components (i.e., allows certain components to pass through more quickly than others). Such components can include molecules, ions, or particles.

[0020] As used herein, "microporous membrane" refers to a material that has a network of small pores.

[0021] As used herein, "natural convection" refers to the flow or movement of a liquid such as water or a gas such as air, in which the fluid motion is not generated by any external source (such as a pump, fan, suction device, etc.), but rather by portions of the fluid that are heavier than other portions.

[0022] "Non-energized" means that the product is passive and does not need to be powered by an external energy source. In particular, the product does not need to be powered by a heat source, gas, or electric current. The product may be configured as an energized device. An exemplary energized device may be an electrical device. The energized device may be an air freshener operated from an electrical outlet or a battery in an automobile, having a wick and / or membrane as described in the following description for transporting the freshening composition and / or evaporating the freshening composition therefrom, or other heating devices (e.g., a device powered by a chemical reaction such as a catalytic fuel system, a device powered by sunlight, etc.).

[0023] As used herein, "permeable material" refers to any material that allows liquids or gases to pass through, including, but not limited to, drywall, wallpaper, wood, vinyl, plastic, plaster, wallboard, fabric, upholstery, paper, woven fabrics, natural polymers, synthetic polymers, and inorganic materials, and mixtures thereof. Permeable materials may also include residues formed on inanimate surfaces, including, but not limited to, dust particles or grease on inanimate surfaces.

[0024] As used herein, "inanimate surfaces" refers to surfaces including, but not limited to, surfaces found in the home such as fabrics, carpets, floors, walls, carpet pads, towels, and the like.

[0025] As used herein, a "freshening composition" refers to a material that is volatilizable at room temperature and atmospheric pressure without the need for an additional energy source. The composition can be configured for a variety of uses, including, but not limited to, air freshening, deodorization, odor removal, malodor neutralization, pest control, insecticide, insect repellent, medication / medicine, disinfectant, sanitizer, mood enhancer, aromatherapy aid, scented composition, unscented composition, or any other use requiring a freshening composition that acts to condition, modify, or otherwise alter the air or environment of a location. Furthermore, not all of the component materials of the composition need be volatile. Any suitable composition can be used in any amount or in any form, including liquid, solid, gel, or emulsion. Materials suitable for use herein may also include non-volatile compounds, such as carrier substances (e.g., water, solvents, etc.). It should also be understood that when a composition is described herein as being "delivered," "emitted," or "released," this refers to the evaporation of volatile components of the composition, and not necessarily the emanating of non-volatile components of the composition.

[0026] Freshening Composition The freshening composition according to the present invention is substantially free of anionic surfactants and contains from 0.05% to 20% by weight of the composition of the following ingredients: (i) a C5-C8 unsubstituted linear alkenal; (ii) C9-C14 unsubstituted linear alkenal; (iii) Formula (I),

[0027] [ka] [In the formula, R1 is an alkoxyl group or a hydroxyl group; R2 is an alkyl group or hydrogen; R3 is hydrogen; R4 is hydrogen; R5 is an alkyl group or hydrogen; R6 is hydrogen or an alkyl group; When R5 is an alkyl group, R6 is hydrogen, and when R5 is hydrogen, R6 is an alkyl group.

[0028] As described above, by incorporating a mixture of C5 to C8 unsubstituted linear alkenal, C9 to C14 unsubstituted linear alkenal, and phenolic derivative of terpene within the above ranges into the composition of the present invention, the mixture is released from the composition, and the C5 to C8 unsubstituted linear alkenal, C9 to C14 unsubstituted linear alkenal, and phenolic derivative of terpene are attached to a surface including a permeable material to which bacteria are attached, thereby making it possible to freshen the surface, prevent bacterial growth on the permeable material, and reduce the bad odor caused by bacteria in the internal environment.

[0029] Specifically, the data in Example I show that a composition of the present invention having a mixture of a C6 alkenal ((E)-2-hexen-1-al), a C10 alkenal ((E)-2-decen-1-al), and a phenolic derivative of a terpene according to formula (I) (e.g., thymol) in a total weight percent of the composition provides an antibacterial activity value of greater than 2 against Gram-positive bacteria (Staphylococcus aureus) and Gram-negative bacteria (Klebsiella pneumoniae), corresponding to a bacterial growth reduction of greater than Log2.

[0030] The phenolic derivative of terpene according to Formula I can be selected from the group consisting of thymol, carvacrol, eugenol, isoeugenol, cinnamyl alcohol, vanillin, benzyl alcohol, and mixtures thereof. The technical effect of selecting a phenolic derivative of terpene from the above group is that these compounds are perfume raw materials compatible with C5-C8 unsubstituted linear alkenals and C9-C14 unsubstituted linear alkenals, allowing for the formulation of freshening compositions that can provide a fresh scent while offering the secondary benefit of preventing bacterial growth.

[0031] The freshening composition may be configured with a weight ratio of the C5-C8 unsubstituted linear alkenal and the C9-C14 unsubstituted linear alkenal to the phenolic derivative of the terpene according to formula (I) of 1:50 to 50:1, preferably 1:20 to 35:1, more preferably 1:2 to 20:1, or a combination of different weight ratios within the above ranges. The technical effect of the weight ratios is that the amounts of the C5-C8 unsubstituted linear alkenal, the C9-C14 unsubstituted linear alkenal, and the phenolic derivative of the terpene according to formula (I) can be adapted according to the volume of the internal environment, in which the freshening composition is applied so that the C5-C8 unsubstituted linear alkenal, the C9-C14 unsubstituted linear alkenal, and the phenolic derivative of the terpene according to formula (I) are present in sufficient amounts to provide freshening and antibacterial effects. For example, in one embodiment of a freshening composition for use in an interior occupancy space such as a passenger compartment of a vehicle, the freshening composition may be comprised of a C9-C14 unsubstituted linear alkenal and a phenolic derivative of a terpene according to formula (I) in a weight ratio of 2:1. In another embodiment of a freshening composition for use in an interior occupancy space such as a toilet, the freshening composition may be comprised of a C9-C14 unsubstituted linear alkenal and a phenolic derivative of a terpene according to formula (I) in a weight ratio of 7:1.

[0032] The freshening composition may be comprised of a weight ratio of C9-C14 unsubstituted linear alkenal to the phenolic derivative of terpene according to formula (I) of 1:50 to 50:1, preferably 1:20 to 30:1, more preferably 1:4 to 10:1. Without wishing to be bound by theory, a technical advantage of combining an amount of C9-C14 unsubstituted linear alkenal with the phenolic derivative of terpene according to formula (I) is that it allows for a balanced scent of the freshening composition, as the characteristic odors of the individual components do not feature prominently in the overall scent profile of the freshening composition.

[0033] The freshening composition may be comprised of an (E)-2 C9-C14 unsubstituted linear alkenal to a phenolic derivative of a terpene according to formula (I) in a weight ratio of 1:50 to 50:1, 1:20 to 20:1, 1:4 to 2:1, or a different combination of the above upper and lower weight ratio limits, or any combination of weight ratios within the above ranges.

[0034] The freshening composition may be substantially free of anionic surfactants and may comprise an (E)-2 C9 to C14 unsubstituted linear alkenal and a surfactant represented by formula (I):

[0036] The phenolic derivative of terpene according to formula (I) may comprise a weight amount of the composition that corresponds to the amount of the (E)-2 C9-C14 unsubstituted linear alkenal, such as up to 15% by weight of the composition, 0.006% to 10% by weight, 0.01% to 7% by weight, or any combination of the above upper and lower percentage limits, or any combination of percentages within the above ranges.

[0037] The freshening composition may be composed of a weight ratio of the C5-C8 unsubstituted linear alkenal to the C9-C14 unsubstituted linear alkenal of 10:1 to 1:10, 5:1 to 1:5, 3:1 to 1:3, or a combination of different weight ratios within the above upper and lower limits, or any combination of weight ratios within the above ranges.

When the freshening composition is configured for use with a delivery member such as a membrane, the C9-C14 unsubstituted linear alkenal may be at a concentration of 1% to 10%, 2% to 8%, 3% to 5% by weight of the composition, or a different combination of the above upper and lower percentage limits, or any combination of percentages within the above ranges.

[0043] The C5-C8 unsubstituted linear alkenal may comprise 0.01% to 10% by weight, 0.02% to 8% by weight, 0.03% to 5% by weight of the composition, or a different combination of the above upper and lower percentage limits, or any combination of percentages within the above ranges.

All parts, percentages, and ratios herein are expressed as weight percent unless otherwise specified. [Example]

[0054] Sample preparation and materials 1) Inventive Compositions - Inventive compositions according to the present invention can be obtained by mixing appropriate amounts of thymol and alkenal with perfume oils to achieve the desired composition. Table 1 below lists the inventive mixtures, and Table 2 lists the inventive freshening compositions according to the present invention for different interior environments with different volumes / spaces. 2) Device - The resulting mixture can be injected into any device configuration capable of releasing the mixture. In this case, 2.6 mL of the mixture was injected into a fragrance delivery device designed for use in a car, and 6.5 mL of the mixture was injected into a fragrance delivery device designed for use in a toilet or bathroom. These devices are membrane-based and deliver fragrance continuously without electrical current. 3) Surfaces—Surfaces to which the present freshening compositions may be applied include, but are not limited to, polyurethane synthetic leather and nylon fabric, both commonly found in automobile interiors, as well as metal towels, vinyl cushions, and floor mats commonly found in toilets and bathrooms. Each surface is cut to the desired size and autoclaved. In Example II below, the synthetic leather was cut into one 5 cm x 5 cm piece, the nylon fabric into four 2 cm x 2 cm pieces, the metal towels into nine 2 cm x 2 cm pieces, the vinyl cushion into three 2 cm x 2 cm pieces, and the floor mat into one 2 cm x 2 cm piece, and the surfaces were autoclaved at 121° C. for 15 minutes at 15 psi.

[0056] [Table 2] * Other ingredients include fragrance ingredients for comfort purposes only and do not contain trans-2-hexenal, trans-2-decenal, trans-4-decenal or thymol. ** Other ingredients include wetting surfactants, solvents, and odor counteractants.

[0057] Test Method I. Test Method for Deposition of Freshening Compositions on Surfaces in an Interior Environment The procedure for applying the formulation to the surface is as follows. 1) Activating the device and allowing the formulation to be released. 2) Place the device and test surface in a sealed environment. Car, toilet, and bathroom simulation: 0.35m 3 A box made of acrylic material having a volume of 3) Leave the device alone. Car simulation: The box cover is opened for 2 hours and then closed, and the fan inside the box is turned on for 1 hour each day. Total elapsed days are 6 days. Toilet and bathroom simulation: The box is always covered. Total elapsed time is 3 days. 4) A control sample (without any formulation) of each test surface is also prepared.

[0058] II. Test method for bacterial growth prevention effect Treated surfaces are tested using test methods for evaluating the antibacterial effectiveness of air freshening products developed from JIS L1902 for nylon cloth, metal cloth and floor mats, and JIS Z2801 for synthetic leather and vinyl cushions.

[0059] The Japanese Industrial Standards (JIS) L 1902 method, entitled "Test Methods for Antibacterial Properties and Antibacterial Effect of Textile Products," is a known JIS method used to test the antibacterial activity of fabrics and fibers that have been treated with antibacterial agents to prevent bacterial growth for a specified period of time.
