1 / 48 “COMPOSITION, METHOD OF PRODUCTION OF THE COMPOSITION AND CONSUMER PRODUCT” FIELD OF DISCLOSURE

[0001] The present disclosure relates to a substrate with an aromatic emulsion printed and dried on its surface. The present disclosure also relates to methods of producing such printed and dried substrate. The present disclosure also relates to the consumer product or consumer packaging comprising such printed and dried substrate. BACKGROUND TO THE REVELATION

[0002] The prolonged and controlled release of flavors and / or fragrances from a substrate is a trend in the aroma distribution sector. Conventionally, the substrate is treated with an aromatic oil by spraying, coating, or immersion. Alternatively, the filaments are treated with an aromatic oil before manufacturing. However, the effect of the transmitted aroma is usually short-lived.

[0003] Furthermore, combining a fragrance with certain active ingredients, such as surfactants, can result in poor fragrance retention. While microencapsulation of aromatic oils can provide fragrance protection, microencapsulation can be expensive and involve additional processes.

[0004] Therefore, an effective, economical and sustainable technology is needed for the controlled release of a flavor and / or fragrance from a substrate, which protects the flavor and / or fragrance and releases the flavor and / or fragrance under predetermined conditions. BRIEF DESCRIPTION OF THE REVELATION

[0005] The present disclosure provides a composition for releasing an aroma (e.g., flavor and / or fragrance). The composition comprises a substrate and an aromatic emulsion imprinted and dried on a surface of the substrate, wherein the aromatic emulsion comprises (i) an aroma, Petition 870250087620, dated 09 / 26 / 2025, page 57 / 119 2 / 48 (ii) a carrier comprising a modified starch and a disaccharide and / or a disaccharide alcohol and, optionally, (iii) a retention aid. BRIEF DESCRIPTION OF THE FIGURES

[0006] The achievements are illustrated in the attached Figures to enhance understanding of concepts as presented in this document.

[0007] Figure 1 illustrates different conditions under which an aroma imprinted on a substrate can be released. The imprinted aroma can be used in indoor applications to consistently provide aroma to a free space by slow diffusion. Alternatively, the aroma can be released by repeated activation by abrasion, sudden release by adding water, controlled release by heating, or activation by delamination of a protective layer. Furthermore, the aroma can be released through various combinations of these methods.

[0008] Figure 2A illustrates patterns of emulsion dots imprinted on the surface of a substrate. Two different emulsions can be imprinted side-by-side on segments of a substrate surface covering large areas. The aromas in each dry emulsion can be released simultaneously in response to the same trigger (e.g., water) or be released individually by different triggers.

[0009] Figure 2B illustrates patterns of emulsion dots imprinted on the surface of a substrate. Two different emulsions can be imprinted side-by-side on segments of a substrate surface in alternating rows. The aromas in each dry emulsion can be released simultaneously in response to the same trigger (e.g., water) or be released individually by different triggers.

[0010] Figure 3 shows the fragrance retention under ambient conditions of the fragrance emulsion printed and dried on a substrate sheet. Petition 870250087620, dated 09 / 26 / 2025, page 58 / 119 3 / 48 compared to pure fragrance oil pipetted onto a substrate sheet. In Figure 3, “FR” stands for fragrance, “Impression” stands for printed and dried fragrance emulsion, and “Pure Oil” stands for pure fragrance oil.

[0011] Figure 4 shows the average fragrance retention in freshly prepared and printed samples at 8 weeks of age, with dot sizes of 10-70%. The percentage dot size is a printer setting that modulates the percentage of voltage applied to control the nozzle opening. 100% means the nozzle is fully open. Dot sizes have the following order of increase: 10% < 20% < 40% < 70%. 10% dot size corresponds to 0.256 mg wet dot weight, 20% dot size corresponds to 0.319 mg wet dot weight, 40% dot size corresponds to 0.627 mg wet dot weight, and 70% dot size corresponds to 1.061 mg wet dot weight. In Figure 4, “Fresh” means recently prepared, dried, printed fragrance emulsion, and “8 weeks” means fragrance emulsion stored for 8 weeks.

[0012] Figure 5A shows the fragrance retention of individual fragrance ingredients (p1-p26) under ambient conditions in printed fragrance emulsion.

[0013] Figure 5B shows the fragrance retention of individual fragrance ingredients (p1-p26) under ambient conditions in pure fragrance oil pipetted onto the substrate.

[0014] Figure 6A shows sensory tests of printed fragrance emulsion samples compared to pure fragrance oil samples before abrasion testing. In Figure 6A, “Printed adhesive” means the adhesive substrate with the fragrance emulsion printed and dried on it, and “Pure oil adhesive” means the adhesive substrate with the pure fragrance oil pipetted on it. Petition 870250087620, dated 09 / 26 / 2025, page 59 / 119 4 / 48

In some embodiments, the aromatic emulsion comprises from about 20% by weight to about 80% by weight, from about 32% by weight to about 80% by weight, from about 40% by weight to about 70% by weight, or from about 50% by weight to about 65% by weight of water, based on the weight of the aromatic emulsion. Petition 870250087620, dated 09 / 26 / 2025, page 72 / 119 17 / 48

[0048] In some embodiments, the aromatic emulsion (before drying) has a viscosity of at least 10 cP (centipoise), 20 cP, 40 cP, 50 cP, 100 cP, 200 cP, 300 cP, 400 cP, 500 cP, 600 cP, 700 cP, 800 cP, 900 cP or 1000 cP at room temperature (about 20 °C). In some embodiments, the aromatic emulsion (before drying) has a viscosity of at most 10000 cP, 9000 cP, 8000 cP, 7000 cP, 6000 cP, 5000 cP, 2000 cP, 1000 cP, 500 cP or 100 cP at room temperature (about 20 °C). In some embodiments, the aromatic emulsion (before drying) has a viscosity in the range of 5 cP to 100 cP at room temperature (about 20 °C).

[0049] In some embodiments, the printed and dried aromatic emulsion comprises no more than 15%, 12%, 10%, 8%, 6%, 5% or 4% water, by weight, based on the weight of the aromatic emulsion. In some embodiments, the printed and dried aromatic emulsion comprises from 4% to 10% or from 4% to 8% water, by weight, based on the weight of the aromatic emulsion. In some embodiments, the printed and dried aromatic emulsion has a water activity (at 25 °C) of 0.1 to 0.6, 0.2 to 0.5 or 0.2 to 0.4. The term “water activity”, as used herein in relation to a substance, means the partial vapor pressure of water in the substance at a given temperature divided by the partial vapor pressure of pure water at the same temperature.

[0050] The substrate surface may be made of a polymer selected from the group of polyester, polyurethane, polysaccharide (e.g., pullulan, cellulose, regenerated cellulose, such as rayon), polypropylene, polyethylene, polyvinyl alcohol (PVOH), gelatin, alginate, starch (e.g., a modified starch or natural starch, such as tapioca starch), hydroxypropyl methylcellulose (HPMC), silk (i.e., polypeptides, such as sericin and / or fibroin), nylon (i.e., aliphatic or semi-aromatic polyamides), wool (i.e., keratin polymer) and combinations thereof. In some embodiments, the Petition 870250087620, dated 09 / 26 / 2025, page 73 / 119 18 / 48 The substrate surface is made of leather, glass, metal, ceramic, rubber, paper, cotton, rayon, plastic film, food product (e.g., chewing gum, snack or biscuit) or a combination thereof. It has been surprisingly found that the composition comprising an aromatic emulsion printed and dried on the substrate surface made of a polymer selected from the group of polyester, polyurethane, polypropylene, polyethylene, cellulose and combinations thereof can have improved aroma retention in the composition, compared to a corresponding composition that has a substrate surface made of certain other polymers (e.g., PVOH). Consequently, preferably the substrate surface is made of a polymer selected from the group of polyester, polyurethane, polypropylene, polyethylene, cellulose and combinations thereof.

[0051] In some embodiments, the printed and dried aromatic emulsion comprises no more than 50% by weight, 45% by weight, 40% by weight, 35% by weight, 30% by weight, 25% by weight or 20% by weight of aroma, based on the weight of the printed and dried aromatic emulsion on a moisture-free basis; the carrier comprises from 5% by weight to 80% by weight, from 5% by weight to 70% by weight, from 10% by weight to 70% by weight, from 10% by weight to 60% by weight, from 10% by weight to 50% by weight or from 10% by weight to 40% by weight of maltose, based on the weight of the carrier; The substrate surface is made of a polymer selected from the group of PVOH, HPMC, gelatin, pullulan, methylcellulose, polyvinylpyrrolidone (PVP), pectin, and combinations thereof. In some embodiments, the substrate surface is made of a polymer selected from the group of PVOH, HPMC, and combinations thereof. It has been found that such embodiments can achieve high aroma retention.

[0052] In some embodiments, the printed aromatic emulsion and Petition 870250087620, dated 09 / 26 / 2025, p. 74 / 119 19 / 48 dry comprises from 10% by weight to 50% by weight, from 20% by weight to 50% by weight, from 20% by weight to 40% by weight, from 25% by weight to 50% by weight, from 15% by weight to 45% by weight, from 25% by weight to 45% by weight, from 15% by weight to 40% by weight, from 25% by weight to 40% by weight or from 15% by weight to 35% by weight of aroma, based on the weight of the aromatic emulsion printed and dried on a moisture-free basis; The carrier comprises from 5% by weight to 90% by weight, from 5% by weight to 80% by weight, from 5% by weight to 70% by weight, from 5% by weight to 60% by weight, from 5% by weight to 50% by weight, from 10% by weight to 80% by weight, from 10% by weight to 70% by weight, from 10% by weight to 60% by weight, from 10% by weight to 50% by weight or from 10% by weight to 40% by weight of maltose, based on the weight of the carrier; and the substrate surface is made of a polymer selected from the group of polyester, polyurethane, polypropylene, polyethylene, cellulose and combinations thereof.It has been found that such solutions can achieve high aroma retention.

[0053] In some embodiments, the printed and dried aromatic emulsion comprises from 40% by weight to 70% by weight, from 45% by weight to 70% by weight, from 50% by weight to 70% by weight or from 55% by weight to 70% by weight of aroma, based on the weight of the printed and dried aromatic emulsion on a moisture-free basis; The carrier comprises 5% to 80% by weight, 5% to 70% by weight, 5% to 60% by weight, 10% to 80% by weight, 10% to 70% by weight, 10% to 60% by weight, 10% to 50% by weight, or 10% to 40% by weight of maltose, based on the weight of the carrier; and the substrate surface is made of a polymer selected from the group of polyester, polyurethane, polypropylene, polyethylene, cellulose, and combinations thereof. Such embodiments have been found to achieve high aroma retention.

[0054] In some embodiments, the printed aromatic emulsion and Petition 870250087620, dated 09 / 26 / 2025, pp. 75 / 119 20 / 48 dry comprises 60% to 70% by weight of aroma, based on the weight of the aromatic emulsion printed and dried on a moisture-free basis; the carrier comprises 10% to 65% by weight, 20% to 65% by weight, 30% to 65% by weight, 40% to 65% by weight, 45% to 65% by weight, or 50% to 65% by weight of maltose, based on the weight of the carrier; and the substrate surface is made of a polymer selected from the group of polyester, polyurethane, polypropylene, polyethylene, cellulose, and combinations thereof. Such embodiments have been found to achieve high aroma retention.

[0055] The substrate can be single-layered or multi-layered. In some embodiments, the substrate is multi-layered, that is, the substrate has two or more layers. Each of the two or more layers can be composed of the same material or of a different material (e.g., polymer). Whether single or multi-layered, each layer of the substrate can be composed of one or more materials and can be in the form of a film, tape, sheet, wet wipe, bag, adhesive, food packaging, insert, or pad.

[0056] In some embodiments, the aromatic emulsion printed and dried on the substrate surface can be protected (to prevent aroma release or loss) by applying a removable adhesive cover film / sheet or a removable adhesive backing layer to the printed substrate surface. For example, a fine fragrance can be printed onto an adhesive, and a pre-treated cover sheet with a pressure-sensitive adhesive can be applied to the adhesive surface containing the printed fragrance, so that removing the cover sheet allows the customer to experience the fragrance. Consequently, in some embodiments, the composition further comprises an adhesive cover film or backing layer on the printed substrate surface. Petition 870250087620, dated 09 / 26 / 2025, page 76 / 119 21 / 48

[0057] Aroma release can be controlled by a variety of application conditions, for example, heat, diffusion, repeated abrasion, water and / or humidity, removal of a removable adhesive film from the printed surface, or by various combinations thereof. (Figure 1) Aroma release can also be controlled by adjusting printing parameters such as dot size, dot spread, and / or the composition of the aromatic emulsion.

[0058] The present disclosure also provides a method for producing the composition described in the present disclosure to create a desired consumer experience. The method comprises: (a) providing the aromatic emulsion comprising (i) the aroma, (ii) the carrier comprising modified starch, disaccharide and / or disaccharide alcohol and, optionally, (iii) the retention aid; (b) printing the aromatic emulsion onto the substrate surface; and (c) drying the printed aromatic emulsion onto the substrate surface. In some embodiments, the aromatic emulsion is printed onto the substrate surface in a predetermined pattern or design, i.e., the location and quantity of the aromatic emulsion to be printed onto the substrate surface are determined before printing. The aromatic emulsion may be printed as letters, numbers or geometric shapes, including, but not limited to, squares, circles or dots, triangles, rectangles, hexagons, etc.A design can be made up of characters, words, or text, as well as other resources such as graphics, images, or logos. In some aspects, the aromatic emulsion is printed as individual dots that, collectively, provide a shape or design.

[0059] In some embodiments, the aromatic emulsion is printed onto the substrate surface in a matrix (e.g., a dot matrix), wherein the matrix comprises a pattern of dots evenly distributed and spaced from center point to center point from 1 mm to 30 mm between dots. Petition 870250087620, dated 09 / 26 / 2025, page 77 / 119 22 / 48 (See Figure 2). In some embodiments, the points have center point spacing of 1 mm to 20 mm or 1 mm to 10 mm between points. In some embodiments, the points have substantially the same diameter and center point spacing of 1.1 times the diameter to 3 times the diameter, or 1.1 times the diameter to 2 times the diameter, or 1.1 times the diameter to 1.5 times the diameter.

[0060] In some embodiments, the aromatic emulsion may be prepared or provided by means of the following steps, that is, step (a) may comprise the following steps: (a1) preparing an aqueous phase by dissolving and / or dispersing the carrier and, optionally, the retention aid with water, (a2) preparing an oily phase comprising the aroma, and (a3) ​​mixing the oily phase with the aqueous phase to generate an oil-in-water emulsion. In some embodiments, the oily phase and the aqueous phase are first mixed to form a thick emulsion, and the thick emulsion is then subjected to shear forces (e.g., a high-speed homogenizer) to generate the aromatic emulsion that will be printed. In some embodiments, the aromatic emulsion is generated at a shear rate in the range of 10,000 rpm to 30,000 rpm or 12,000 rpm to 25,000 rpm, for a period of about 3 minutes to 15 minutes or about 5 minutes to 10 minutes.In some embodiments, the generated aromatic emulsion is diluted (e.g., with water or aqueous solution or suspension) and / or supplemented with an additional additive (e.g., solid particle, surfactant, dye, colorant or pigment, gum and / or additional active ingredient, etc.) before being printed onto the substrate surface.

[0061] In step (b), the aromatic emulsion is imprinted onto the substrate surface. In some embodiments, the aromatic emulsion may be imprinted, dripped, or deposited directly onto the substrate surface in a controlled and precise manner in a predefined pattern, for example, a dot pattern or design. In this respect, the “imprinting” according to the present Petition 870250087620, dated 09 / 26 / 2025, pp. 78 / 119 The 23 / 48 method is distinct from spraying (emulsification on substrate), coating (emulsification on substrate), atomizing (emulsification on substrate), or dipping (substrate in emulsion), which applies the emulsion to the substrate in an uncontrolled, non-uniform, or random pattern (spraying or atomization) or without uncoated areas on the substrate surface (coating or dipping). Furthermore, in contrast to spraying, coating, atomizing, or dipping, droplets of the aromatic emulsion in the present method can be imprinted at a predetermined size to modulate one or more of the amounts of aroma on the substrate, the amount of aroma released, the dot dispersion, or the compatibility with the substrate.

[0062] A printing assembly can be used to print the aromatic emulsion onto the substrate surface. The printing assembly can be a non-contact printing assembly, for example, an inkjet-type print head or a set of nozzles that drop or deposit the emulsion onto a surface; or a contact printing assembly, for example, a flatbed screen, a rotary screen, a reverse rotogravure, or a flexographic printing assembly. In some embodiments, the printing assembly is a non-contact printing assembly. In some embodiments, the aromatic emulsion is fed to a non-contact printing assembly that prints or deposits the aromatic emulsion in individual droplets onto the substrate surface that directly receives the printed aromatic emulsion.As used in this document, the term "non-contact print assembly" means a print assembly that does not touch or come into contact with the substrate surface during the printing process.

[0063] There are two types of jetting modes for contactless printing assemblies, continuous mode (CM) and drop-on-demand (DOD). In continuous mode jetting, an uninterrupted jet of fluid is projected from an orifice; Rayleigh instabilities cause the jet to... Petition 870250087620, dated 09 / 26 / 2025, pp. 79 / 119 24 / 48 break into individual droplets after a certain flight distance. In on-demand drop mode, individual droplets are ejected from an orifice, usually as a result of a pulsed energy source.

[0064] In some embodiments, the aromatic emulsion is imprinted or deposited in individual droplets on the surface of the substrate that directly receives the imprinted aromatic emulsion. In some embodiments, the droplets have an average diameter of 100 microns to 5 mm, or 425 microns to 5 mm, or 1 mm to 4 mm. In some embodiments, the droplets have substantially the same diameter. A droplet smaller than 425 microns (i.e., a particle that passes through a 40-mesh sieve) is considered dust. In some embodiments, each individual droplet has a diameter greater than 425 microns.

[0065] In step (c), the printed aromatic emulsion is dried on the surface of the substrate. The printed aromatic emulsion can be dried by, for example, infrared, conduction, convection, or a combination thereof. In some embodiments, the printed aromatic emulsion is air-dried. In some embodiments, the printed aromatic emulsion is air-dried at a temperature of 30 °C to 160 °C, or 30 °C to 110 °C, or 40 °C to 100 °C, or 40 °C to 90 °C. In some embodiments, the printed aromatic emulsion is air-dried at a temperature not exceeding 100 °C. In some embodiments, the relative humidity (RH) of the air supplied to dry the printed aromatic emulsion is not more than 35% RH, 15% RH, 7% RH, or 1% RH. In some embodiments, the printed aromatic emulsion is dried with desiccated air. In some embodiments, the drying process may be conducted under an inert gas atmosphere. Examples of inert gases include nitrogen, carbon dioxide, and noble gases such as argon.In some embodiments, the drying process is conducted under an atmosphere of nitrogen gas. In practice, the inert gas atmosphere may still contain small amounts of oxygen. Petition 870250087620, dated 09 / 26 / 2025, pp. 80 / 119 25 / 48 Typically, an inert gas atmosphere has an oxygen level of less than 90 g of oxygen per cubic meter of atmosphere, or less than 50 g of oxygen per cubic meter of atmosphere, or less than 30 g of oxygen per cubic meter of atmosphere, or less than 25 g of oxygen per cubic meter of atmosphere, or less than 23 g of oxygen per cubic meter of atmosphere.

[0066] In some embodiments, the printed aromatic emulsion is dried with a radiant heat source. Examples of suitable radiant heat sources include, but are not limited to, infrared light devices and other radiant electric heaters and radiant gas heaters. In some embodiments, the printed aromatic emulsion is dried with infrared light. In some embodiments, the printed aromatic emulsion is dried with infrared light in combination with conduction and / or convection.

[0067] In some embodiments, one or more steps of the method may be repeated. For example, the aromatic emulsion (i.e., the first emulsion) may be printed and dried on a substrate surface, and a second emulsion may subsequently be printed on the same substrate surface and dried. In some embodiments, the aromatic emulsion (i.e., the first emulsion) is printed on a substrate surface, a second emulsion is printed on the same substrate surface, and both the aromatic emulsion and the second emulsion are dried simultaneously. In some embodiments, the second emulsion is printed onto the aromatic emulsion (i.e., the first emulsion), i.e., droplets of the second emulsion are printed onto the surface of the droplets of the aromatic emulsion, and the emulsions are dried. In some embodiments, the second emulsion is printed onto the substrate surface at a location or area adjacent to the location where the aromatic emulsion (i.e., the first emulsion) is printed on the substrate surface.Refer to Figure 2A and Figure 2B. Consequently, the composition of the present disclosure may additionally comprise a second emulsion printed and dried on. Petition 870250087620, dated 09 / 26 / 2025, pp. 81 / 119 26 / 48 substrate surface, on which the second emulsion is printed over or adjacent to the aromatic emulsion.

[0068] Like the aromatic emulsion (i.e., the first emulsion), the second emulsion may also comprise (i) a second aroma, (ii) a second carrier comprising a second modified starch and a second disaccharide and / or a second alcohol disaccharide and, optionally, (iii) a second retention aid. In some embodiments, at least one component of the aromatic emulsion (i.e., the first emulsion) and the second emulsion is different. In such embodiments, the at least one component that is different may be the aroma, the carrier, or the retention aid, or alternatively, an additional additive. For example, the aromatic emulsion and the second emulsion may have the same aroma, carrier, and retention aid, wherein the aromatic emulsion comprises a blue pigment and the second emulsion comprises a red pigment.As another example, the aromatic emulsion may comprise a carrier that has a different aroma release profile or trigger than the carrier in the second emulsion, such that the aroma in the aromatic emulsion and the aroma in the second emulsion are released at different times, different rates, or by different triggers (e.g., water, heat, pH, etc.). In some embodiments, the second emulsion may comprise an ingredient that is incompatible with an ingredient in the aromatic emulsion (i.e., first emulsion). In this way, incompatible ingredients may be provided on the same substrate but not in the same emulsion. Ingredient incompatibility may include, but is not limited to, the potential for a reaction between the ingredients, an ingredient that may have a negative effect on aroma retention, and the like.For example, the abundance of surfactant used in cleaning products can affect fragrance retention, so printing the fragrance and surfactant separately would be beneficial. Another example is the reaction of two ingredients. Petition 870250087620, dated 09 / 26 / 2025, p. 82 / 119 27 / 48 when mixed: sodium nitrite reacts with citric acid under moisture to release nitric oxide, which can be used for meat storage. Thus, the composition of the present disclosure can accommodate two or more incompatible ingredients.

[0069] In some embodiments, the method of the present disclosure further comprises the application of a retention aid to the surface of the substrate. In such embodiments, the retention aid in the aromatic emulsion and the retention aid applied to the surface of the substrate may be the same or different. In some embodiments, a retention aid is applied only to the surface of the substrate, but is not added to the aromatic emulsion.

[0070] In some embodiments, the method of the present disclosure further comprises a step of applying a removable adhesive cover film / sheet or removable adhesive backing layer to the printed surface of the substrate.

[0071] The printing of the aromatic emulsion according to the present method provides a significant advantage over the application of a pure aroma oil to a substrate. With pure aroma oils, the volatile compounds vaporize rapidly, resulting in a rapid aroma release profile and a reduction in intensity over time. In comparison, the release of an aroma printed on the surface of a substrate according to the present method can be modulated by selecting the carrier, retention aid, dot size, and / or dot spread to release the aroma under one or more specified conditions. As used herein, “dot spread” refers to the area over which a printed dot spreads on the substrate surface. In other words, “dot spread” refers to the contact area between the printed dot and the substrate surface.

[0072] The present disclosure also provides a product of Petition 870250087620, dated 09 / 26 / 2025, p. 83 / 119 28 / 48 consumer product or consumer packaging comprising the composition of the present disclosure. Examples of consumer products or consumer packaging include, but are not limited to, a storage container or bag to impart a scent to the item being stored; a transport item, such as a bed sheet, that releases a calming or invigorating fragrance on demand (e.g., by scraping the surface); a pillow stuffing with a calming fragrance (e.g., lavender) printed on it to aid sleep; a food packaging stuffing that releases flavor to a food upon diffusion, heat, and / or contact with moisture; a tea bag that releases flavor to a food upon heat and / or contact with moisture; hygiene or personal care products, such as tissues or toilet paper, that release a scent when applied to the skin; a shoe insert that releases a compound to mask odors and / or fragrance when inserted into the shoe or when compressed while walking;A garbage bag that releases a compound to mask odors and / or fragrance; fabric care sheets, such as laundry sheets that release fragrance when exposed to the heat of a dryer; sheets, wipes, or cleaning pads that release a scent when rubbed (scraped) on a surface; cleaning pads that release fragrance when wet; and abrasion-activated car mats or doormats that release fragrance when someone walks on or steps on them.

[0073] Thus, the composition of the present disclosure can be used in various aroma applications in household care, personal care, beauty care, food deodorization, fine fragrances, sleep, pest control, cleaning, scented wet wipes and the like. Furthermore, the composition of the present disclosure can be used in food packaging, flavor distribution and other functional aroma applications, such as antimicrobial, antifungal or antioxidant. Other Petition 870250087620, dated 09 / 26 / 2025, page 84 / 119 29 / 48 applications may include medicinal aromatics to promote health, well-being and environmental cleanliness.

[0074] Many aspects and realizations have been described above and are merely illustrative and not limiting. After reading this descriptive report, those skilled in the art will recognize that other aspects and realizations are possible without departing from the scope of the invention. EXAMPLES

[0075] The following non-limiting examples are provided to further illustrate the present invention and should not be construed as limitations of the invention, as many variations of the present invention are possible without departing from its spirit or scope. EXAMPLE 1: TEST METHODS

[0076] Activation Tests. The printed substrates (i.e., the substrate with the aromatic emulsion printed and dried on it) were tested for activated aroma release by abrasion. The printed substrates were repeatedly abraded over a period of days, and aroma release and aroma profile were evaluated.

[0077] Other activation methods can also be tested, including contact with water and lamination. Laminating a cover film over the printed substrate surface can completely conceal the aroma and provide a burst of aroma when the cover film is removed. The cover film can be reapplied to the printed substrate surface and removed and reapplied repeatedly to release bursts of aroma. Alternatively, water can be added to the printed substrate to dissolve the aromatic emulsion and provide a burst of aroma. Additionally, exposing the aromatic emulsion to high humidity can be used to release aroma continuously.

[0078] Abrasion Test for Aroma Emulsion Adhesion Petition 870250087620, dated 09 / 26 / 2025, page 85 / 119 30 / 48 Printed on Substrate. An abrasion tester was used to quantitatively test the adhesion of the printed aromatic emulsion to substrates. The abrasion tester controlled the number of blows and the frequency of abrasion. The printed substrate samples were taped to the support surface under abrasive. The abrasive was inside the support and was a piece of rubber disc with a diameter of 0.25 inches and a hardness of 70A. A certain weight was added on top to increase abrasion resistance. In use, the abrasive was applied continuously in a reciprocating motion over the sample for a predefined number of strokes. The number of blows the printed aromatic emulsion survived with a certain load weight provided an indication of how well the printed aromatic emulsion adhered to the substrate.

[0079] Aroma Retention Under Ambient Conditions. The aroma retention and olfactory sensoriality of printed aromatic emulsions were compared with those of pure aromatic oil. Samples of pure aromatic oil were prepared by pipetting 20 mg of pure aromatic oil onto a nonwoven polyurethane substrate in a dot pattern similar to that of the printed aromatic emulsion. The printed aromatic emulsion also contained 20 mg of the same aromatic oil on the same size and type of substrate. Samples were aged in a traffic-free room for up to 4 weeks under ambient conditions (room temperature, 20-70% relative humidity) and subsequently subjected to sensory tests, followed by gas chromatography tests to quantitatively measure aroma retention. EXAMPLE 2: PREPARATION OF THE PRINTED SUBSTRATE

[0080] A thick emulsion was prepared including the ingredients listed in Table 1. The term “wet percent,” as used in this disclosure, means the percentage by weight (of an ingredient) based on the total weight of the emulsion, including water. Using a high-speed homogenizer Petition 870250087620, dated 09 / 26 / 2025, page 86 / 119 31 / 48 shear, the thick emulsion was reduced to a thin emulsion. The thin emulsion was then printed onto two different substrate sheets, namely a nonwoven polyurethane and a hydroentangled nonwoven polyester, using a piezo-driven REA Jet valve with 350 µm nozzles. TABLE 1 Ingredients Percentage of moisture Water 54.7% Modified starch with OSA 6.9% Fragrance oil 28.8% Maltose 8.6% Glycerin 1.0% Sodium Lauryl Sulfate 0.03% Blue #1 0.005% Total 100.0%

[0081] The printed substrate sheets were dried with infrared (IR) light for 2 minutes. The printed substrate sheets had a fragrance load of 0.6-2.1 mg / cm2 with varying spot sizes and spot-to-spot distances.

[0082] The performance of the printed substrate sheets was tested in 12-liter containers with a fragrance load ranging from 20 mg to 80 mg. Regardless of the load density, all sheets released fragrance for at least 5 months with occasional opening (once a week) and for at least 3 weeks with frequent opening (opened once a day and left open for 5 minutes before being closed again), with some variation in intensity depending on the substrate material, dot size, and amount of fragrance. In particular, larger printed dots showed slower release at the beginning and greater retention at the end of the 5-month test.

[0083] Abrasion Tests. Following the test method of Example 1, the printed and dried fragrance emulsion showed excellent adhesion to the substrate sheets, surviving >120 movements with 250 g of added weight. Petition 870250087620, dated 09 / 26 / 2025, page 87 / 119 32 / 48

[0084] Aroma Retention Tests. Following the test method of Example 1, the printed and dried fragrance emulsion showed much improved overall fragrance retention over time compared to pure fragrance oil samples (Figure 3). Furthermore, the printed and dried fragrance emulsion preserved the overall fragrance very well, with a fragrance retention of >90% after 4 weeks of exposure. In contrast, the pure fragrance oil samples showed a drastic loss of overall fragrance from the first day, and fragrance retention decreased to 20% after 3 days of exposure and 5% after 4 weeks of exposure (Figure 3).

[0085] It was found that dot size affects fragrance retention and fragrance release rate in freshly prepared samples and after storage for 8 weeks (Figure 4). Larger dots exhibited greater protection of the fragrance contained within them and therefore delayed fragrance diffusion from the printed and dried fragrance emulsion. This was reflected in the fragrance retention and release profiles.

[0086] Gas chromatography (GC) analysis indicated that the printed fragrance emulsion protected highly volatile ingredients from premature release (Figure 5A) compared to the pure fragrance oil sample (Figure 5B). For the pure fragrance oil sample, the highly volatile ingredients showed significant loss on the first day, with complete loss of the most volatile ingredient p1, retention of only 5% of the highly volatile ingredient p2, and retention of 20% of the volatile ingredient p3. On day 3, the 12 most volatile ingredients (p1-p12) in the pure fragrance oil sample were completely lost, and the remaining ingredients (p13-p26) continued to decrease over time. After 2 weeks, only the low-volatile ingredients (p23-p26) were still detectable by GC in the pure fragrance oil sample, and of the 26 ingredients, only 4 ingredients (p23-p26) were still retained at a retention of 50-60%. See Figure 5B. Petition 870250087620, dated 09 / 26 / 2025, pp. 88 / 119 33 / 48 comparison, the printed fragrance emulsion sample showed excellent retention of all ingredients over the 4-week period, with only a small loss of some of the highly volatile ingredients. See Figure 5A.

[0087] Activation Tests. Following the test method of Example 1, the printed substrate sheets were subjected to activation by abrasion. Printed samples of fragrance emulsion and pure fragrance oil samples of the same age were paired for direct comparison. Before abrasion, when the samples were fresh, the pure fragrance oil samples exhibited much higher fragrance intensity than the printed fragrance emulsion samples, a difference that gradually decreased as the exposure time increased (Figure 6A). After 1 week, the printed fragrance emulsion samples and the pure fragrance oil samples showed very similar intensities, and after 2 weeks, the printed fragrance emulsion samples surpassed the pure fragrance oil samples. These results demonstrated that the printed fragrance emulsion provided better fragrance stability over time than the pure fragrance oil.

[0088] After abrasion of the samples, it was found that abrasion activated the printed fragrance emulsion samples and released the fragrance, causing the printed fragrance emulsion samples to immediately smell much stronger (Figure 6B). In comparison, the pure fragrance oil samples showed no change in fragrance intensity after abrasion (Figure 6B). The printed and worn fragrance emulsion samples showed greater fragrance intensity than the pure fragrance oil samples on the first day. Furthermore, the olfactory intensities and top notes of all printed and worn fragrance emulsion samples at different times of Petition 870250087620, dated 09 / 26 / 2025, pp. 89 / 119 34 / 48 exposures were very similar. These results demonstrated the excellent retention of all volatile fragrance ingredients in the printed fragrance emulsion throughout the test period. EXAMPLE 3: FLAVOR PRINTED ON POLYESTER FILM FOR FROZEN FOOD PACKAGING

[0089] A flavor emulsion was prepared using the ingredients listed in Table 2. The flavor oil droplets in the emulsion had an average oil droplet size smaller than 1 micron. The flavor emulsion was printed onto a polyester film to form dots of different sizes. The printed flavor emulsion was then dried and evaluated for flavor retention. The analysis found that a larger printed dot size increased flavor retention.

[0090] The printed flavor emulsion was also air-dried at 67 °C or 100 °C and analyzed for flavor retention. Printed and dried flavor emulsions were analyzed at 0, 4, and 8 weeks of storage. It was found that the printed flavor emulsions, dried at 67 °C or 100 °C, maintained almost 100% flavor retention during the 8 weeks of storage.

[0092] A coffee-flavored emulsion was prepared using the ingredients listed in Table 5. The emulsion was printed onto a polyester film and dried. A portion of the film containing 150 points, providing 6.7 mg of coffee-flavored oil, was taped to the lid of a coffee cup. For comparison, a control was prepared by dosing 0.67 g of 1% pure coffee flavor directly into a second cup with a white film taped to the lid. Boiling water (100 ml) was added to each cup and the lids were taped to the cups, respectively.

[0093] A trained panel of individuals analyzed the intensity of the coffee aroma (scale of 0 to 10) upon opening the lid. The results of the sensory evaluation demonstrated that the printed polyester film exhibited a greater coffee aroma than the pure coffee-flavored oil sample throughout the evaluation (Table 6). The printed polyester film sample was perceived as significantly stronger than the control at each time point.

[0094] A chicken-flavored emulsion was prepared using the ingredients listed in Table 7. The emulsion was printed onto a polyester film and dried. A 7.62 cm x 7.62 cm (3”x3”) strip of the printed polyester film, containing approximately 19 mg of chicken-flavored oil, was taped to the lid of a container containing 100 g of frozen cauliflower rice. For comparison, a control was prepared by dosing 0.19 g of 10% pure chicken-flavored oil directly onto the cauliflower rice with a white film taped to the lid. Both the printed sample and the control sample were microwaved for 2 minutes and allowed to cool for 1 minute before the lid was removed (T-0) and the samples were evaluated for chicken aroma intensity.

[0095] A trained panel of individuals analyzed the intensity of the chicken aroma (scale of 0 to 10) upon opening the lid. The results of the sensory evaluation demonstrated that the printed polyester film presented a chicken aroma equal to or greater than that of the control (pure chicken-flavored oil sample) (Table 8).
