Description

Technical Field

[0001] This application relates to the field of aerosol generating articles, and particularly to a composition for preparing aerosol generating articles and an aerosol generating article. Background Technology

[0002] Aerosol-generating products can form aerosols through ignition or atomization, or through a heat-non-combustible method. Heat-non-combustible aerosol-generating products utilize an external heat source to heat the aerosol-generating matrix just enough to release aerosols without burning.

[0003] Heated tobacco products using aerosol generation can reduce harmful substances produced by combustion by about 90%, while also significantly reducing the release of sidestream smoke and ambient smoke. These new types of tobacco products are gradually becoming a trend in the industry. However, heated tobacco products also have quality defects such as a weaker smoke flavor and aroma, resulting in a poorer smoking experience.

[0004] Therefore, there is a need for an improved aerosol-generating article that can solve or mitigate at least one of the problems existing in the prior art. Summary of the Invention

This enhances the adhesion between the components and the processing stability of the product, thereby improving the intermolecular adhesion within the prepared components and enhancing the quality of the aerosol-generated product. Furthermore, the high specific surface area of ​​the polysaccharides facilitates the adsorption of fragrance components in the composition, creating a microscopic encapsulation effect.

The compositions of this application are all food and pharmaceutical additives, safe, non-toxic, and environmentally friendly. They do not produce any inhalable hazardous substances during extraction, nor do they decompose to generate harmful substances, thus contributing to improved safety of the aerosol-generated product.

[0036] Typically, aerosol generating products include a media section and a functional section, such as a plug, cooling section, support section, filtration section, and filter. Heated non-combustible aerosol generating products reduce a large amount of harmful substances produced by combustion, but also reduce the characteristic aroma of aerosol generating products, thus lowering the user's inhalation experience.

[0037] In view of this, the first aspect of this application provides a composition for preparing a component of an aerosol-generating article. The composition of this application can improve the retention rate of fragrance components in the component of the aerosol-generating article, thereby improving the sustained release of aroma from the aerosol-generating article and enhancing its quality.

[0038] The composition of this application includes: a smoke-generating agent component; a curing agent; a fragrance component; an adhesive; and a skeleton component, said skeleton component including polysaccharides.

[0039] In this application, the smoke-generating agent component generates an aerosol through heating and atomization, which is beneficial for increasing the amount of smoke produced by the aerosol-generated product. In some embodiments, the smoke-generating agent component includes one or more of propylene glycol, glycerol, sorbitol, glucomannan, and triethyl citrate. The above-mentioned smoke-generating agent component has good smoke-generating properties, which is beneficial for increasing the amount of smoke produced by the aerosol-generated product and improving the user's vaping satisfaction. In some preferred embodiments, the smoke-generating agent component includes one or both of propylene glycol and glycerol. In some embodiments, the content of the smoke-generating agent component is 5%-25% based on the total mass of the composition. By keeping the content of the smoke-generating agent in the composition within the above range, it is beneficial for increasing the amount of smoke produced by the aerosol-generated product and improving the user's satisfaction. For example, based on the total mass of the composition, the content of the smoke-generating agent component can be 5%, 8%, 10%, 12%, 15%, 18%, 20%, 22%, 25%, or a value between any two of these values.

[0040] The curing agent is selected from inorganic mineral materials or natural cellulose materials, providing a framework and carrier for components in the preparation of aerosol-generating products. In some embodiments, the curing agent includes one or more of calcium carbonate, talc, kaolin, diatomaceous earth, and natural plant fibers. Among these, calcium carbonate, talc, kaolin, and diatomaceous earth are safe; calcium carbonate and talc are food additives and are used in pharmaceuticals; kaolin and diatomaceous earth are used in the paper industry. The curing agent, when mixed with the framework components, provides a supporting framework for the components of the aerosol-generating products and a carrier for other components in the composition, such as fragrance components. Furthermore, the aforementioned inorganic curing agent components can act as lubricants, reducing friction between the slurry and the molding equipment during the molding process, improving processing performance, and enhancing the surface smoothness of the molded components. Natural plant fibers are derived from substances that are both food and medicine, and are highly safe. In addition, their use with inorganic curing agent components can improve the strength and hardness of the components. Furthermore, some plant fibers have specific fragrances, which can enhance and supplement the aroma. In some preferred embodiments, the curing agent comprises one or more of calcium carbonate, talc, and diatomaceous earth. In some embodiments, the content of the curing agent is 15%-45% based on the total mass of the composition. Maintaining the curing agent content within the above range is beneficial for improving the strength and hardness of the component. Exemplarily, the content of the curing agent, based on the total mass of the composition, can be 15%, 20%, 25%, 30%, 35%, 40%, 45%, or a value between any two of these values.

[0041] Flavoring components provide characteristic aromas in aerosol-generated articles, enhancing the user's inhalation experience. In some embodiments, the flavoring components include one or more of solid and liquid flavorings. Solid flavorings refer to substances that remain solid at room temperature (e.g., in block, granule, or flake form) and possess a specific aroma. Solid flavorings have a pure aroma and a slow-release characteristic during inhalation of the aerosol-generated article, which helps improve the aroma consistency of the aerosol-generated article. Liquid flavorings refer to substances that remain liquid or have fluidity at room temperature and possess a specific aroma. Liquid flavorings can provide a rich variety of aromas and offer a better inhalation sensation. Furthermore, liquid flavorings can be easily and uniformly dispersed in the composition, improving the uniformity of the aerosol-generated article. In addition, liquid flavorings also improve the processability of the composition and enhance the quality of the prepared components. In some embodiments, the solid flavoring includes one or more of clove powder, kudzu root powder, gel flavoring, and microcapsule flavoring. In some embodiments, the liquid flavoring includes one or more of menthol, eugenol, and tobacco extract. In some embodiments, the content of the fragrance component is 5%-20% based on the total mass of the composition. This is beneficial for improving the aroma perception of the aerosol-generated article. For example, the content of the fragrance component based on the total mass of the composition can be 5%, 8%, 10%, 12%, 15%, 18%, 20%, or a value within a range of any two of these values.

[0042] The adhesive achieves close contact with the material interfaces of each component in the composition by wetting, generating intermolecular attraction, thereby binding the powders, liquids, etc., of the component materials. In some embodiments, the adhesive includes one or more of sodium carboxymethyl cellulose, xanthan gum, sodium alginate, guar gum, tamarind gum, and pullulan. These adhesive components are safe and widely available. In some embodiments, the content of the adhesive, based on the total mass of the composition, is 5%-30%. This is beneficial for giving the aerosol-generated article a stable and robust structure. Exemplarily, the content of the adhesive, based on the total mass of the composition, can be 5%, 8%, 10%, 15%, 20%, 25%, 30%, or a value within the range of any two of these values.

[0043] In this application, the composition further includes a backbone component, which comprises polysaccharides. In some embodiments, the polysaccharides include one or more of cellulose, microcrystalline cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, amyl starch, amyl starch, and modified starch. These polysaccharides possess the property of forming a strong interfacial film, which can improve the intermolecular adhesion within the components of the prepared aerosol-generated product and enhance product processing stability. This is beneficial for maintaining the smoothness of the outer surface of the prepared components, improving aesthetics, and thus facilitating the transport of aerosol substances. Furthermore, these polysaccharides have a high specific surface area, providing more binding sites for fragrance components, which is beneficial for adsorption and binding with fragrance components, forming a microscopic encapsulation effect. This is beneficial for improving fragrance retention during the preparation of the aerosol-generated product and for the uniform and slow release of fragrance components during the aerosol-generated product's extraction process, improving extraction consistency and thus enhancing the user experience. In some embodiments, the content of the backbone component is 15%-50% based on the total weight of the composition. This is beneficial for improving the quality of the aerosol-generated product. For example, the content of the skeleton component, based on the total weight of the composition, can be 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, or a value between any two of these values.

[0044] In this application, "fragrance retention rate" is quantitatively calculated as the ratio of fragrance component content in the parts before and after molding of the aerosol-generated article. The fragrance retention rate (%) = (fragrance component content after molding / fragrance component content before molding) × 100%. The content of the fragrance component can be measured using methods known to those skilled in the art, such as gas chromatography-mass spectrometry. In this application, the terms "fragrance component retention rate" and "fragrance retention rate" are used interchangeably.

[0045] In some embodiments, based on the total mass of the composition, the content of the smoke-generating agent component is 10%-20%; the content of the curing agent is 30%-40%; the content of the fragrance component is 5%-10%; the content of the adhesive is 5%-10%; and the content of the skeleton component is 30%-40%. By keeping the content of each component in the composition within the above ranges, it is beneficial to adjust the viscosity of the composition, improve the processing performance of the composition, and thereby improve the quality of the components of the prepared aerosol-generating article. Furthermore, the content of the smoke-generating agent component within the above ranges also helps to increase the amount of smoke produced by the aerosol-generating article. The content of the fragrance component within the above ranges also helps to improve the aroma quality of the aerosol-generating article. The content of polysaccharides within the above ranges also helps to improve the fragrance retention rate of the composition during the preparation of components of the aerosol-generating article, and also helps to improve the mechanical properties of the prepared components.

[0046] In some embodiments, the composition further includes water. Adding water to the composition facilitates thorough and uniform mixing of the various components, helps adjust the viscosity of the composition, improves its processability, avoids problems such as material buildup or clogging during preparation, or incomplete composition formation, and improves the quality of the prepared parts.

[0047] In some embodiments, the ratio of the total mass of the components other than water to the mass of water in the composition is 1:0.1 to 0.3. By keeping the water content in the composition within the above range, it is beneficial for the slurry formed by mixing the composition and water to have suitable viscosity and flowability, thereby facilitating molding and improving the quality of the components of the prepared aerosol-generated articles.

[0048] In some embodiments, the curing agent has a powder particle size of 60-200 mesh. In some embodiments, the adhesive has a powder particle size of 60-200 mesh. In some embodiments, the polysaccharide substance has a powder particle size of 60-200 mesh. This is beneficial for improving the processing performance of the composition, avoiding problems such as pore blockage during the preparation process, and improving the quality of the prepared parts.

[0049] In some embodiments, the solid fragrance has a particle size of 100-200 mesh. This facilitates uniform dispersion of the solid fragrance components in the composition, improves aroma consistency, enhances the processing performance of the composition, and improves the quality of the prepared components.

[0050] In some embodiments, the aerosol generating article is selected from combustible aerosol generating articles, heated non-combustible aerosol generating articles, and / or atomized aerosol generating articles.

[0051] The following is in conjunction with the appendix Figure 1-4 The structure of the aerosol-generating article of this application is illustrated by way of example.

[0052] In some implementations, reference Figures 1 to 2 The aerosol generating article includes a matrix segment 20, a functional segment 30, and an encapsulation layer (not shown). The encapsulation layer covers the circumferential exterior of the functional segment and the aerosol generating matrix.

[0053] The matrix segment 20 has two axial ends, namely a proximal lip end 20a and a distal lip end 20b. The proximal lip end 20a refers to the end of the matrix segment 20 that is closer to the user's lips when the user uses the aerosol-generated product, and the distal lip end 20b refers to the end of the matrix segment 20 that is farther away from the user's lips when the user uses the aerosol-generated product.

[0054] This application does not limit the specific structure of the functional section 30, which includes at least one of the following: the front plug section 10, the filter section 31, the support section 32, and the cooling section 33.

[0055] The coating layer can protect the aerosol-generating matrix. The coating layer includes, but is not limited to, one or more of the following materials: fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, polyethylene (PE), polybutylene terephthalate (PBAT).

[0056] In some implementations, please refer to Figure 1 and Figure 2 The functional section 30 includes one or more of the following: a filter section 31, a support section 32, and a cooling section 33. The functional section is located near the lip end 20a of the matrix section 20.

[0057] In some implementations, such as Figure 1 As shown, the functional segment 30 includes a filter segment 31, which is disposed near the lip end 20a of the matrix segment 20 along its axial direction. The aerosol generated by the aerosol generating matrix is ​​transported to the filter segment under suction negative pressure. The filter segment is used to filter and / or adsorb some particulate matter and harmful substances in the aerosol, improving the user's suction experience and enhancing the safety of the aerosol-generated products. Furthermore, the process of the aerosol being loosened by the filter segment before reaching the user can reduce the temperature of the aerosol, mitigating the "burning" sensation when the user inhales the aerosol.

[0058] In some implementations, such as Figure 2 The functional section includes a filter section 31, a support section 32, and a cooling section 33. The support section 32 is located at one end of the matrix section 20 along its axial direction, one end of the cooling section 33 is located at the end of the support section 32 away from the matrix section 20 along its axial direction, and the filter section 31 is located at the other end of the cooling section 33.

[0059] The support section 32 can connect and support the matrix section 20 and the cooling section 33 at both ends. The cooling section 33 is used to reduce the temperature of the aerosol so that the temperature of the aerosol flowing out of the filter section 31 is suitable and avoids the problem of the aerosol being "hot to the mouth".

[0060] Of course, the positions of the support section and the cooling section can also be interchanged, that is, the cooling section 33 is connected to one end of the matrix section 20 along the axis, and the two ends of the support section 32 are connected to the other end of the cooling section 33 and the filter section 31, respectively.

[0061] In some implementations, reference Figure 3 and Figure 4The functional section 30 includes one or more of the following: a pre-plug section 10, a filter section 31, a support section 32, and a cooling section 33. One or more of the filter section 31, support section 32, and cooling section 33 are disposed at one end of the aerosol generating matrix 20 along its length, and the pre-plug section is disposed at the other end of the aerosol generating matrix 20 along its length. The encapsulation layer wraps around the circumferential exterior of the functional section and the matrix section. The pre-plug section improves the problem of aerosol generating matrix 20 detachment. Furthermore, the pre-plug section 10 can adsorb the condensed and refluxed aerosol after the aerosol generating product stops pumping, thereby avoiding the problem of aerosol condensation flowing downwards and causing internal contamination of the aerosol generating device, making it difficult to clean, and preventing cross-contamination of flavors when pumping different flavored aerosol generating products.

[0062] In some implementations, such as Figure 3 As shown, the aerosol generating article includes a pre-plug section 10, a matrix section 20, a cooling section 33, a filter section 31, and a coating layer (not shown). The pre-plug section is located at the distal lip end 20b of the aerosol generating matrix, the cooling section is located at the proximal lip end 20a of the aerosol generating matrix, and the filter section is located at the other end of the cooling section away from the aerosol generating matrix.

[0063] In some implementations, such as Figure 4 As shown, the aerosol generating article includes a pre-plug section 10, a matrix section 20, a support section 32, a cooling section 33, a filter section 31, and a coating layer. The pre-plug section is located at the distal lip end 20b of the aerosol generating matrix, the support section 32 is located at the proximal lip end 20a of the aerosol generating matrix, and the cooling section 33 is located at the end of the support section 32 axially away from the aerosol generating matrix 20. The filter section 31 is located at the end of the cooling section 33 axially away from the support section 32.

[0064] This application does not limit the structure of the functional section and / or the front plug section. In some exemplary embodiments, such as Figure 5 As shown, the functional section and / or the forepump section itself have numerous micropores, which are interconnected to form micro-channels. It can be understood that after the functional section is formed, the gaps between its raw material components constitute micropores. These micropores are irregular and belong to the category of pores in a microscopic sense. The size of the micropores is determined by the gaps between the powder components after the powder is formed.

[0065] During the aerosol generation process, the generated aerosols can enter the microchannels of the functional section. Under the negative pressure generated by suction, the aerosols are transported to the user for inhalation through the microchannels. In addition, as the aerosols flow through the microchannels, it also helps the functional section capture some substances in the aerosols and has a cooling effect.

[0066] In other exemplary embodiments, such as Figure 6 and Figure 7As shown, the functional section and / or the forepump section are provided with at least one air passage hole, which penetrates the end faces of opposite ends of the functional section along the axial direction. The air passage hole helps to improve the air permeability of the functional section and reduce suction resistance.

[0067] It should be noted that the airway pores mentioned above are pores in a macroscopic sense, while micropores are pores in a microscopic sense. The cross-sectional area of ​​an airway pore is much larger than that of a micropore, for example, at least 20 times larger.

[0068] The micro-airways are connected to the airway pores. Since the micro-airways are formed by the interconnection of micropores, the micropores are also connected to the airway pores. Furthermore, it can be understood that the interconnection between micropores can be partial, with some micropores not connected, or all micropores can be interconnected. A portion of the aerosol in the micro-airways can also be collected at the airway pores and delivered to the user's mouth under the negative pressure of suction. The airway pores help reduce the suction resistance for the user, improving the user experience. It should be noted that suction resistance is positively correlated with the flow resistance of the aerosol; the lower the flow resistance of the aerosol, the lower the perceived suction resistance, and vice versa.

[0069] In some embodiments, the components of the aerosol-generating article are selected from one or more of a matrix section, a pre-plug section, a cooling section, a support section, and a filter section. Using the composition of this application to prepare the above-mentioned components is beneficial for improving the retention rate of fragrance components, thereby enhancing the sustained release of fragrance components during the inhalation process of the aerosol-generating article, improving aroma consistency, and thus improving the user's inhalation experience.

[0070] In some embodiments, the components of the aerosol generating article are manufactured using a one-piece molding process. This one-piece molding process overcomes the problems of lint shedding, residue shedding, and difficulty in cleaning that occur during the aerosol generating article's suction process. This improves the user experience.

[0071] In some embodiments, the integral molding process is selected from one or more of extrusion molding, injection molding, die casting, and 3D printing. Extrusion molding refers to a processing method in which a raw material composition is added to an extruder, and the material is simultaneously heated and plasticized by the action between the extruder barrel and screw, and continuously pushed forward by the screw through the die head to form products or semi-finished products of various cross-sections. The functional components formed by extrusion molding are strip-shaped. Because the functional components, such as the aerosol generating matrix, are an integral structure, the aerosol generating product remains a unified medium after heating or cessation of heating, preventing disintegration and falling off, thus reducing problems such as filament shedding, residue shedding, and difficulty in cleaning.

[0072] In some embodiments, the integral molding process is carried out under constant temperature conditions, wherein the constant temperature is 30℃-200℃. Performing the integral molding process at these temperatures facilitates good viscosity and flowability of the components in the composition, improves the molding stability of the composition, and also helps to improve the quality consistency and stability of the prepared parts, reducing production energy consumption. The constant temperature process also reduces thermal stress impact and extends the service life of the production mold. Exemplarily, the constant temperature can be 30℃, 50℃, 80℃, 100℃, 120℃, 150℃, 180℃, 200℃, or a value between any two of these values. Exemplarily, performing the integral molding process under constant temperature conditions specifically includes: heating the composition to a set temperature, and then molding the composition, for example, by extruding the heated composition using a screw extruder. Exemplarily, the extrusion molding process parameters also include a screw speed of 50-200 r / min. For example, the screw speed can be 50 r / min, 100 r / min, 150 r / min, 200 r / min or a range of any two of these values.

[0073] In some embodiments, the integral molding process is performed under segmented temperature variations, comprising: a first stage temperature of 30℃-80℃; a second stage temperature of 90℃-110℃; a third stage temperature of 120℃-160℃; and a fourth stage temperature of 170℃-200℃. Performing the integral molding process under segmented temperature variations facilitates uniform heating of the components in the composition, potentially promoting the dispersion of additives or fillers, improving the mixing and homogenization of the slurry, and enhancing the extrusion smoothness and formability of the composition, thereby improving the quality of the aerosol-generated product. Furthermore, performing the integral molding process under segmented temperature variations is suitable for situations where materials in the composition need to avoid thermal decomposition, such as flavored slurry components. Since flavoring substances are easily decomposed at high temperatures, the integral molding process under segmented temperature variations allows for a gradual increase in temperature, reducing flavor loss. This can improve the mixing and homogenization of the slurry.

[0074] A second aspect of this application also provides an aerosol-generating article comprising components prepared using the composition described in the first aspect of this application. This improves the mechanical strength of the components and the retention rate of fragrance components in the aerosol-generating article, thereby enhancing the aroma quality and improving the user's inhalation experience. The number of components prepared using the composition of this application in the aerosol-generating article is not limited; those skilled in the art can choose any component prepared using the composition of this application as needed. Exemplarily, the aerosol-generating article of this application includes at least one of a matrix section, a pre-plug section, a cooling section, a support section, and a filter section prepared using the composition of this application. In some preferred embodiments, the aerosol-generating article includes a matrix section, a pre-plug section, a cooling section, a support section, and a filter section prepared using the aforementioned composition.

[0075] Aerosol generating products are used in conjunction with aerosol generating devices, which include heating components and power supply components. The power supply components provide electrical energy to the heating components, which convert the electrical energy into other forms of energy and apply them to the aerosol generating matrix in the matrix section, thereby heating the aerosol generating matrix to generate aerosols for users to inhale.

[0076] This application also provides an aerosol generation system. The aerosol generation system includes an aerosol generation apparatus with a heating component and the aerosol generation article described above. Specifically, the heating component heats and atomizes the aerosol generation matrix to generate aerosols.

[0077] The present application will be described in further detail below with reference to specific embodiments. The purpose of this description is merely illustrative and not intended to limit the scope of this disclosure.

The slurry composition was extruded and molded, resulting in a high degree of formability of the extruded part. The extruded part was then dried at 150℃ for 30 seconds to obtain a component of the aerosol-generated product.

[0088] Weigh out 40 parts by weight of cellulose (skeletal component), with a particle size of 150 mesh; 5 parts by weight of propylene glycol (smoke-generating component); 5 parts by weight of triethyl citrate (smoke-generating component); 35 parts by weight of talc (curing agent), with a particle size of 120 mesh; 5 parts by weight of peppermint flavoring (fragrance component); 5 parts by weight of pullulan (adhesive), with a particle size of 120 mesh; 5 parts by weight of sodium carboxymethyl cellulose (adhesive), with a particle size of 120 mesh; and 16 parts by weight of deionized water. Mix thoroughly to form a slurry. The slurry has a water content of 20.12% and a bulk density of 0.401 g / cm³. 3 In the extrusion apparatus, the extrusion temperature was set to 80℃ and the screw speed to 160 r / min. The composition slurry was extruded and molded, resulting in a high degree of formability of the extruded part. The extruded part was then dried at 150℃ for 30 seconds to obtain a component of the aerosol-generated product.

[0089] Comparative Example 1

[0090] The components for the aerosol-generating product were prepared using a method similar to that in Example 1, except that no polysaccharide (skeleton component) was added to the composition. The specific formulation was 20 parts by weight of propylene glycol (VG, smoke-generating agent component); 65 parts by weight of talc (curing agent) with a particle size of 100 mesh; 10 parts by weight of solid tobacco flavoring (flavoring component); 5 parts by weight of sodium carboxymethyl cellulose (adhesive) with a particle size of 120 mesh; and 20 parts by weight of deionized water.

[0091] Extrusion process parameter testing

[0092] The extrusion pressure and torque of the composition slurry during extrusion molding were tested using a thermoscientific system on a screw extruder. Higher extrusion pressure and torque indicate greater forces during extrusion and lower extrusion smoothness.

[0093] Physical parameter testing of components of aerosol-generated products

[0094] Hardness and roundness tests were conducted using a five-function integrated testing bench, PTV R-H502225T. The hardness test method followed the GB / T 22838.6-2009 standard. Higher roundness and hardness values ​​indicate better part forming, higher mechanical strength of the finished product, and higher quality of the aerosol-generated product.

[0095] Testing of fragrance component retention rate during extrusion process

[0096] The content of fragrance components in the extrusion component before and after extrusion was determined using an Agilent 8890GC-5977B MS gas chromatograph-mass spectrometer, and the fragrance loss rate was calculated according to the following formula:

[0097] Fragrance component retention rate (%) = (Fragrance component content after extrusion / Fragrance component content before extrusion) × 100%

[0098] The components prepared in Examples 1-4 and Comparative Example 1 were tested according to the above method for their process parameters, physical parameters and fragrance component retention rate. The results are recorded in Table 1 below.

[0099] Table 1

[0100]

[0101] The results above show that the pressure and torque of the compositions in Examples 1-4 were lower than those in Comparative Example 1 during extrusion, indicating that the addition of polysaccharides to the compositions helps reduce the viscosity of the slurry, improves its fluidity, and facilitates smooth extrusion. The hardness and roundness of the extruded parts from Examples 1-4 were higher than those from Comparative Example 1, indicating that polysaccharides help improve the physical properties of the extruded products, thereby improving the quality of the aerosol-generated products. The fragrance retention rate of the parts from Examples 1-4 was higher than that of Comparative Example 1 during extrusion, indicating that polysaccharides help improve the retention rate of fragrance components, thereby improving the aroma quality of the aerosol-generated products and enhancing the user's sensory experience.
