Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of essence composition, more particularly, it relates to a pet deodorizing essence composition and a preparation method thereof. BACKGROUND

[0002] In modern society, raising pets has become a common lifestyle, and pets have entered more and more families, bringing emotional comfort and joy to people. However, a series of problems inevitably arise during pet feeding, among which pet odor and bacterial growth seriously affect the quality of living environment and life experience. The body odor of pets, the odor emitted by excrement, and the odor left in their activity areas such as pet beds and toys, diffuse in the indoor air, not only making the living environment unsuitable, but also possibly causing health problems such as allergies.

[0003] There are various methods and products for pet deodorization, mainly including physical, chemical, biological, and plant types. Physical deodorization removes odor through physical adsorption of porous substances, using intermolecular van der Waals forces to adsorb odor molecules. Chemical deodorization neutralizes odor molecules through oxidation, reduction, addition, and other chemical reactions to generate odorless substances. Biological deodorization uses microorganisms to decompose odor molecules and convert them into harmless substances. Plant deodorization uses natural ingredients in plant extracts to neutralize odors.

[0004] Traditional deodorization only relies on strong fragrance to mask odors and cannot eliminate odor molecules from the source, which is a temporary solution rather than a permanent one. Although it can reduce odor to some extent, many products add chemical synthetic ingredients such as chlorine compounds and aromatic amines, which can irritate the respiratory tract and skin of pets and pose potential threats to human health. Tea polyphenols have a unique chemical structure, and their molecules can tightly bind to odor molecules, undergo chemical reactions, and decompose odor molecules, effectively eliminating various odors caused by pet urine, feces, body odor, and other odors. Tea polyphenols are widely used in pet deodorization as they are non-toxic and have no side effects. At the same time, the environment where pets live is warm and humid, making it an ideal breeding ground for bacteria, fungi, viruses, and other microorganisms. However, most existing deodorizing products have weak disinfecting ability, while essential oil from fragrance plants is rich in active ingredients with antibacterial and anti-inflammatory effects, which can destroy the cell wall and membrane structure of bacteria, fungi, and viruses, interfere with their metabolic processes, effectively kill harmful microorganisms in the pet living environment, and release fresh and natural fragrance, creating a pleasant atmosphere for the pet living space while completing the deodorization and disinfection tasks. Therefore, tea polyphenols are used to achieve deep deodorization and strong disinfection.

[0005] The inventors believe that, in the prior art, the application stability and compatibility of tea polyphenols and essential plant oils are easily affected by temperature changes in the use environment, and when the temperature changes in the use environment are relatively severe, self-oxidation and degradation of different degrees easily occur, and the stability and compatibility of mutual combination are also adversely affected, thereby causing obvious loss of the deep deodorization and strong disinfection effects brought by the application.

[0006] Therefore, there is an urgent need to propose a solution to solve the above technical problems. SUMMARY

[0007] In order to improve the temperature change resistance of tea polyphenols and essential plant oils when used in combination, and to achieve excellent and stable deep deodorization and strong disinfection effects, the present application provides a pet deodorizing essential composition and a preparation method thereof, and a first aspect, the present application provides a pet deodorizing essential composition, which adopts the following technical solution: A pet deodorizing essential composition is made of raw materials containing the following weight parts: Tea polyphenols 5-15 parts; Biological enzyme 20-30 parts; Double-dealcohol 20-30 parts; Deionized water 35-45 parts; Essential plant oil 0.3-3 parts; Preservative 1-2 parts; Structure protective agent 6-10 parts; The structure protective agent is prepared by the following method: S1, the starch raw material is mixed with water, heated and stirred, and alkali is added to adjust the pH during stirring, then sodium trimetaphosphate is added for reaction, and after the reaction is completed, acetic anhydride is added for further reaction, and the pH is adjusted with acid after the reaction, and the intermediate product is obtained after filtration, water washing and drying; S2, the intermediate product obtained in step S1 is dispersed in water, mixed with bamboo fiber powder, and then polyvinyl alcohol is added for continuous stirring reaction, and after the reaction, the product is filtered and dried after vacuum water washing with distilled water, and then crushed and sieved to obtain the structure protective agent; The weight ratio of the intermediate product and the bamboo fiber powder is (3-4):1.

[0008] By using the above technical solution, the biological enzyme recognizes and catalytically decomposes the odor molecules such as urea, hydrogen sulfide, ammonia and volatile fatty acids in pet excrement, and converts them into harmless substances such as odorless water and carbon dioxide, rather than simply covering the odor, and the biological enzyme destroys the bacterial breeding environment while decomposing the odor, reducing pathogenic microorganisms such as E. coli and mold in the environment; therefore, the use of biological enzyme plays an excellent complementary and enhancing effect on the corresponding effect of tea polyphenols and essential plant oils used in combination.

[0009] In the preparation of the structural protective agent, the starch raw material is first added to water and heated and stirred to disrupt the starch granule crystalline structure, promote molecular chain stretching, and provide active sites for subsequent reactions. Sodium trimetaphosphate is then used as a crosslinking agent to construct a three-dimensional network structure, enhancing thermal stability and mechanical strength. Acetic anhydride is then added to the reaction to inhibit the repolymerization of the starch molecular chains and maintain the starch structure stable under temperature fluctuations. After obtaining the intermediate product, it is uniformly mixed with bamboo fiber powder in an aqueous medium. Polyvinyl alcohol is used as an interfacial compatibilizer to form hydrogen bonds and van der Waals forces between the intermediate product and the bamboo fiber powder, thereby forming a stable binding structure and ultimately the structural protective agent. Applying the structural protective agent to the pet deodorant fragrance composition can not only embed the essential oil molecules of the essential plant through the hydrophobic cavity of starch and adsorb tea polyphenols through the porous structure, but also inhibit the volume expansion / contraction caused by temperature fluctuations, protect the internal active ingredients from being stable in form, and reduce volatilization or oxidative decomposition caused by temperature fluctuations, but also form a multi-level barrier effect. Through the multiple protection of barrier + volatilization inhibition + antioxidant, the temperature change resistance of tea polyphenols and essential plant oils when used together can be significantly improved, so that the final pet deodorant fragrance composition can exert a relatively excellent and stable deep deodorization and strong disinfection effect during the application process.

[0010] Preferably, the weight ratio of the intermediate product to the bamboo fiber powder is 3.6:1.

[0011] By adopting the above technical solution, after the intermediate product and bamboo fiber powder in the above weight ratio are combined, the resulting structural protective agent has a better complementary and coordinated effect when used, and can thus exert a relatively excellent protective effect on the combination of tea polyphenols and essential oils of essential plants under a temperature-changing environment, which is conducive to obtaining a pet deodorizing fragrance composition with excellent deep deodorizing and strong disinfecting effects.

[0012] Preferably, the particle size of the bamboo fiber powder is 55-65 μm.

[0013] By adopting the above technical solution, the bamboo fiber powder of the above particle size can form a uniform dispersion when mixed with the intermediate product, reducing the risk of agglomeration, and thus forming a relatively uniform and stable combination between the two. The bamboo fiber powder under this particle size can also form a relatively stable load for tea polyphenols and bring an excellent sustained-release effect to essential oils of essential plants. As a result, after the structural protective agent is applied, the pet deodorant fragrance composition finally obtained can exert a stable and better deep deodorization and strong disinfection effect under a temperature-changing environment.

[0014] Preferably, the particle size of the structural protective agent is 145-155 μm.

[0015] By adopting the above technical solution, the structural protective agent with the above particle size has strong resistance to deformation during temperature change cycles, and can effectively protect tea polyphenols and essential oils of essential plants. Within this particle size range, it can also avoid the rapid leakage of small particles and prevent the failure of sustained release of large particles. Therefore, it can be ensured that after the structural protective agent is applied, the pet deodorizing fragrance composition finally obtained can exert stable and better deep deodorizing and strong disinfection effects under temperature change environment.

[0016] Preferably, 1.5-2.5 parts by weight of a functional additive is further added to the raw material, wherein the functional additive is composed of chitosan and white carbon black, and the weight ratio of chitosan to white carbon black is 1:(4-7).

[0017] By adopting the above technical scheme, white carbon black has a large specific surface area and rich microporous structure, which can tightly adsorb the molecules of essential oils of essential plants and form a protective film to isolate tea polyphenols from contact with oxygen and moisture in the air, thereby slowing down its oxidation process, so that tea polyphenols and essential oils of essential plants can exert better coordination stability under temperature changes; chitosan can form a protective layer structure, and the molecular chain can reconstruct the hydrogen bond network during temperature changes, effectively protecting tea polyphenols and essential oils of essential plants to fully exert stable and excellent coordination effects; and when chitosan and white carbon black are used as functional additives, the two can play an excellent compounding and synergistic role with each other, and the double locking of the adsorption of white carbon black and the dynamic hydrogen bond network formed by the chitosan molecular chain can significantly improve the temperature change resistance of tea polyphenols and essential oils when used together. At the same time, the coordination system formed by the functional additives in the pet deodorant fragrance composition can synergistically complement the action system formed by the structural protective agent, so that the coordination between tea polyphenols and essential oils of essential plants can also exert excellent and stable deep deodorization and strong disinfection effects under temperature-changing environments, thereby obtaining a pet deodorant fragrance composition with better application quality.

[0018] Preferably, the weight ratio of the chitosan to white carbon black is 1:5.5.

[0019] By adopting the above technical solution, when chitosan and white carbon black in the above weight ratio are used in combination, the two can achieve adsorption-antioxidation balance and interfacial stress optimization, thereby making the corresponding effects brought by the functional additives perform better.

[0020] Preferably, the essential oil of the essential plant is composed of the following components in parts by weight: 0.1-1 part white tea essential oil; 0.1-1 part of rosemary essential oil; 0.1-1 parts of honeysuckle essential oil.

[0021] By adopting the above technical solution, white tea essential oil, rosemary essential oil, and honeysuckle essential oil are rich in a variety of active ingredients with antibacterial and anti-inflammatory properties, such as terpenoids and flavonoids. These ingredients can destroy the cell walls and membranes of bacteria, fungi, and viruses, disrupting their metabolic processes, effectively killing various harmful microorganisms in the pet's living environment, greatly reducing the risk of disease transmission and creating a healthy and safe living space for pets and their owners. Furthermore, the three essential oils also have a deodorizing function, which works synergistically with tea polyphenols to significantly enhance the deodorizing effect.

[0022] Preferably, the preservative is one or a combination of dimethylol hydantoin, imidazolidinyl urea, methylisothiazolinone, phenoxyethanol and benzoic acid.

[0023] By adopting the above technical solution, the above types of preservatives are all suitable for the preparation of pet deodorant fragrance compositions, and can extend the storage life of the pet deodorant fragrance compositions, thereby exerting long-lasting and excellent effects.

[0024] In a second aspect, the present application provides a method for preparing a pet deodorant fragrance composition, which adopts the following technical solution: A method for preparing a pet deodorant fragrance composition comprises the following steps: (1) preparing raw materials including tea polyphenols, biological enzymes, double deethanol, deionized water, essential oils of essential plants, preservatives and structural protective agents according to a proportion; (2) After mixing the deionized water, tea polyphenols and biological enzymes in step (1), double deionized alcohol and essential oil of essential plants are added and mixed, after the mixing is completed, a structural protective agent is added and mixed, and finally a preservative is added and mixed to obtain a pet deodorizing fragrance composition.

[0025] By adopting the above technical solution, the above preparation method is simple to operate, the raw materials are added and mixed in steps, which makes it easy to control the quality during the process, and can ensure that the raw materials fully cooperate with each other, which is conducive to obtaining a pet deodorant fragrance composition with excellent quality and stability, and the whole is also suitable for large-scale industrial production.

[0026] In summary, this application has the following beneficial effects: 1. The present application adds a specially prepared structural protective agent to the pet deodorizing fragrance composition, embeds the essential oil molecules of essential plants through the hydrophobic cavity of starch, and absorbs tea polyphenols through the porous structure of bamboo fiber powder, and constructs multiple protections of barrier + anti-volatility + anti-oxidation, thereby significantly improving the temperature-change resistance of tea polyphenols and essential plant oils when used together, so that the final pet deodorizing fragrance composition can exert relatively excellent and stable deep deodorizing and strong disinfection effects during the application process; 2. The present application uses a functional auxiliary agent composed of chitosan and white carbon black, which can double-lock the dynamic hydrogen bond network formed by the adsorption of white carbon black and the chitosan molecular chain, and cooperate with the structural protective agent, thereby significantly improving the temperature-change resistance of tea polyphenols and essential plant oils when used together, and obtaining a pet deodorizing fragrance composition with better application quality.

[0061] Performance Test Test Samples: The pet deodorant fragrance compositions obtained in Examples 1-19 were selected as test samples 1-19, and the pet deodorant fragrance compositions obtained in Comparative Examples 1-4 were selected as control samples 1-4.

[0062] Test method: (1) Odor removal effect test: the main components of the odor in the pet nest are ammonia and hydrogen sulfide. Take a closed space and make the ammonia concentration in the space 10mg / m 3 , hydrogen sulfide concentration is 8mg / m 3 Then, use the pet deodorant fragrance composition to spray into the confined space at a spraying rate of 5g / m 3 The test temperature is 25℃. After 1 hour, the concentrations of ammonia and hydrogen sulfide are measured, and the removal rates of ammonia and hydrogen sulfide are calculated. The average value of the two is recorded as A. A control experiment was also conducted. The difference was that after spraying the pet deodorizing fragrance composition, a temperature ramp of 10-40°C was applied for 1 hour at a rate of 2.5°C / min. The removal rates of ammonia and hydrogen sulfide were calculated, and the average of the two was recorded as A1. Finally, the odor removal effect loss rate is calculated, odor removal effect loss rate = (A-A1) / A. The greater the odor removal effect loss rate, the worse the stability of the pet deodorizing fragrance composition when used in a temperature-changing environment.

[0063] (2) Disinfection effect test: a glass slide carrier was coated with bacterial solution at a concentration of 1.0×10 6 CFU / mL, coating amount is 0.01mL / cm 2 Then, the pet deodorant fragrance composition was sprayed onto the glass slide carrier at a spraying rate of 0.5 mg / cm 2 The test temperature was 25°C and the inhibition rate was determined after 1 hour. The bacterial species used were Staphylococcus aureus (ATCC 6538), Escherichia coli (8099) and Candida albicans (ATCC 10231). The average inhibition rate of the three bacteria was recorded as B. At the same time, a control experiment was set up. The difference was that after spraying the pet deodorizing fragrance composition, a temperature rise and fall of 10-40°C was applied within 1 hour, and the temperature change rate was 2.5°C / min. The average inhibition rate of the three bacteria in the corresponding tests was taken as B1; finally, the loss rate of disinfection effect was calculated, and the loss rate of disinfection effect = (B-B1) / B. The greater the loss rate of disinfection effect, the worse the stability of the pet deodorizing fragrance composition when used in a temperature-changing environment.

[0064] After the above tests were performed on the test samples 1-19 and the control samples 1-4, the test results were recorded in Table 3.

[0065] Table 3 Test results of test samples 1-19 and control samples 1-4 Combining Example 1 and Comparative Examples 1-3 with Table 3, it can be seen that the present application can significantly improve the stability of the pet deodorizing fragrance composition in exerting deep deodorization and strong disinfection effects during application by adding a specially prepared structural protective agent to the pet deodorizing fragrance composition. If only the intermediate product or bamboo fiber powder is added as a structural protective agent, it is found that the stability improvement effect brought by each is limited, and the sum of the improvement effects brought by each of the two is far less than the excellent effect brought by the combination of the two. It can be seen that the embedding of essential oil molecules of essential plants by the hydrophobic cavity of starch and the adsorption of tea polyphenols by the porous structure of bamboo fiber powder can bring about a significant composite synergistic effect, thereby significantly improving the temperature resistance of tea polyphenols and essential oils when used together, so that the final pet deodorizing fragrance composition can exert a relatively excellent and stable deep deodorization and strong disinfection effect during application.

[0066] It can be seen from the combination of Example 1 and Examples 13-17 and Table 3 that by adding the functional adjuvant consisting of chitosan and white carbon black to the pet deodorizing fragrance composition, the temperature change resistance of tea polyphenols and essential plant oils when used together can be further improved, so that the odor removal effect loss rate (%) and the disinfection effect loss rate (%) of the pet deodorizing fragrance composition after the above test are significantly reduced. In combination with Examples 18-19 and Table 3, it can be seen that if chitosan or white carbon black is used alone, although it can reduce the odor removal effect loss rate (%) and the disinfection effect loss rate (%) obtained by the test, the reduction is limited, and the sum of the corresponding effects of the two respective additions is far less than the excellent combination of the two. Therefore, it can be seen that chitosan and white carbon black can bring a corresponding improvement effect of 1+1>2 in the pet deodorizing fragrance composition. In combination with Comparative Examples 3-4 and Table 3, it can be seen that if the structural protective agent is not used in the pet deodorizing fragrance composition, it is found that the corresponding effect brought by the application of the functional adjuvant will be significantly lost. Therefore, it can be seen that the structural protective agent and the functional adjuvant have a synergistic effect, which is beneficial to the excellent protection effect of the combination of tea polyphenols and essential plant oils in the temperature change environment, and the excellent pet deodorizing fragrance composition with deep deodorization and strong disinfection effect is obtained.

[0067] The specific embodiments are only an explanation of the present application, which is not a limitation of the present application. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as the modifications are within the scope of the claims of the present application, they are protected by the Patent Law.
