Description

Technical Field

[0001] This invention relates to the field of odor removal technology, specifically to an odor-removing product. Background Technology

[0002] Human excrement, such as urine, feces, and menstrual blood, often contains alkaline odor compounds like ammonia and trimethylamine, or acidic odor compounds like hydrogen sulfide and isovaleric acid. For users of hygiene products—such as diapers and sanitary napkins—if excrement is not cleaned up promptly, it not only produces unpleasant odors leading to a poor user experience, but also easily breeds bacteria, causing secondary infections. Currently, related deodorization technologies are often limited and incomplete, typically only masking odors or targeting specific odors, resulting in unsatisfactory deodorization effects. Summary of the Invention

[0003] The main technical problem solved by this invention is the poor deodorizing effect of deodorizing products in related technologies.

[0023] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the invention. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present invention are not shown or described in the specification. This is to avoid obscuring the core parts of the invention with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0024] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0025] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages).

[0026] Some embodiments of this application provide an odor-removing product for use in disposable hygiene products such as diapers and sanitary napkins, used to deodorize and inhibit bacteria in human excrement. Specifically, to achieve the above objective, the odor-removing product in the embodiments of this application includes:

[0027] The absorbent has an adsorption surface formed on its surface;

[0028] The neutralizing agent comprises an acidic deodorizer and an alkaline deodorizer, each fixedly disposed on the adsorption surface; the acidic deodorizer is used to neutralize alkaline odor components, and the alkaline deodorizer is used to neutralize acidic odor components.

[0029] And bioinhibitors, which are placed on the adsorption surface to inhibit the growth of microorganisms.

[0030] In this embodiment, the absorbent serves as a carrier for both the neutralizing agent used for odor removal and the bio-inhibitor used for antibacterial purposes in the odor-removing product. The absorbent has an adsorption surface that adsorbs the neutralizing agent and the bio-inhibitor, preventing them from easily detaching from the absorbent and thus enhancing the overall odor-removing and antibacterial effect of the odor-removing product.

[0031] It is worth mentioning that, in addition to adsorbing and retaining neutralizers and biological inhibitors, this absorbent can also adsorb and retain odor sources in excrement to a certain extent. On the one hand, it can prevent odor sources from flowing to other areas, and on the other hand, it can allow odor sources to fully react with neutralizers to enhance their odor removal effect.

[0032] In some alternative embodiments, to enhance the adsorption effect of the absorbent, the absorbent may be made of a material with high specific surface area and / or high porosity. Specifically, the specific surface area of ​​the absorbent may be greater than or equal to 1.5 m². 2 / g means the absorbent is a material with a high specific surface area. This type of material is characterized by a very large total surface area per unit mass / unit volume, typically stemming from its porous structure, nanoscale, or unique morphology. Such materials usually exhibit high adsorption rates, enabling effective adsorption of neutralizing agents and bio-inhibitors. In this case, the absorbent's surface directly serves as the adsorption surface. Alternatively, the absorbent can also be a highly porosity material, with a porosity greater than or equal to 12%. In this case, the pore regions of the absorbent form the adsorption surface, meaning the pore-forming areas can be used as the adsorption surface. It's worth noting that high porosity often implies a high specific surface area.

[0033] Among them, as examples of high specific surface area and high porosity, the absorbent can be natural fibers such as wool and cotton fibers, or activated carbon fibers, or bio-based materials such as cyclodextrin and chitosan.

[0034] To deodorize materials with unpleasant odors, the deodorizing product in this application embodiment also includes a neutralizing agent. This neutralizing agent, depending on the acidity or alkalinity of the odor components, includes both acidic and alkaline deodorizing agents. The acidic deodorizing agent neutralizes alkaline odor components, including ammonia and trimethylamine, thereby removing their odor. The alkaline deodorizing agent neutralizes acidic odor components, including hydrogen sulfide and isovaleric acid, thereby removing their odor. In other words, the deodorizing product in this application embodiment, by adding both acidic and alkaline deodorizing agents, can treat various odor components with different acidity and alkalinity, thus achieving broad-spectrum deodorization, expanding the application scenarios of the deodorizing product, and improving the user experience. Furthermore, compared to deodorization methods that use fragrances to physically mask odors, the acid-base neutralization method used in this application embodiment offers higher safety and avoids the irritation of human skin by chemical substances.

[0035] In some alternative embodiments, in order to neutralize and deodorize alkaline odor components, the acidic deodorizing agent may specifically include food-grade monobasic acid, dibasic acid, or tribasic acid, etc., specifically including at least one of malic acid, lactic acid, and citric acid.

[0036] In some alternative embodiments, in order to neutralize and deodorize acidic odor components, the alkaline deodorizing agent may specifically include at least one of basic amino acids, such as arginine, lysine, and histidine.

[0037] In addition to neutralizing and removing odor components through a neutralizing agent, the odor-removing product in this application embodiment also includes a biological inhibitor to prevent bacterial growth. The purpose of the biological inhibitor is to inhibit the growth and reproduction of microorganisms, including those that cause odors, thereby preventing odor accumulation. In some optional embodiments, the specific type of biological inhibitor may include organic antibacterial agents and / or bio-based materials. Specifically, the organic antibacterial agents may include at least one of PHMB, chlorphenesin, and ammonium salts, with ammonium salts specifically including quaternary ammonium salts. The bio-based materials may include cyclodextrin and / or chitosan, where the chitosan may be modified chitosan.

[0038] In some optional embodiments, to achieve a good odor removal effect, the absorbent in the odor removal product may account for 40%-50% by weight, the acidic deodorizing agent for 20%-30% by weight, the alkaline deodorizing agent for 20%-30% by weight, and the biological inhibitor for 0.05%-5% by weight. For example, a typical composition ratio of the odor removal product may be: 45% by weight of absorbent, 25% each of acidic and alkaline deodorizing agents, and 5% by weight of biological inhibitor.

[0039] In some optional embodiments, for ease of addition and deodorization, the absorbent, neutralizing agent, and bioinhibitor can be formed into microcapsules together using spray drying and / or physical mixing methods. Microcapsules encapsulate trace amounts of substances within non-woven fabric, achieving micro-packaging of these substances without affecting the original chemical properties of the contents (i.e., the absorbent, neutralizing agent, and bioinhibitor). The functions of the contents can be externally manifested through external stimulation or sustained-release action, thereby preventing the loss of effective ingredients in the deodorizing product. In the embodiments of this application, the particle size of the microcapsules is in the range of 100μm-500μm.

[0040] In some alternative embodiments, please refer to Figure 1 The microcapsule 4 can be disposed between any two layers of material between the surface layer 1 and the bottom film 2 of a disposable hygiene product, for example, it can be disposed in the surface layer 1, the bottom film 2, or the core 3 between the two.

[0041] Please refer to Figure 2 Under the same experimental conditions, the temperature was 23±1℃ and the humidity was 50±5%RH. Absorption rate and rewetting were tested according to GB / T 8939 standard; antibacterial performance was tested according to GB 15979-2024 E6.3 carrier antibacterial test; odor removal performance was tested according to GBT 45369—2025 deodorizing effect evaluation method for absorbent sanitary paper products and raw materials; and stability performance was tested by placing the product in an accelerated aging environment (54°C, 75% RH) for 14 days. The experimental results show that the odor-removing product in this application embodiment achieved an antibacterial performance of 95% and an odor removal performance of 90%, and remained active even after 14 days in the accelerated aging environment.

[0042] This application provides an odor-removing product. Since the neutralizing agent in the odor-removing product includes an acidic odor remover and an alkaline odor remover, each of which can neutralize and remove alkaline and acidic odor components to achieve deodorization, and also inhibits the growth of microorganisms based on biological inhibitors to prevent the growth of bacteria, thereby achieving the effects of odor removal and antibacterial activity, and improving the user experience.
