TECHNICAL FIELD
[0001] The present application relates to the technical field of deodorant, in particular to a pet deodorant and a preparation method thereof. BACKGROUND
[0002] With the continuous rise of pet family penetration rate, the odor problem in the home environment is increasingly prominent, becoming one of the core pain points of pet owners. The generation of such odor is derived from multi-dimensional odor sources, such as ammonia generated by urea contained in cat and dog excrement after decomposition by urease, which is the main irritating odor source; at the same time, pet dander, residual saliva, and long-term use of wet litter, all of which will form a persistent odor source, together destroying indoor air quality. The current market deodorizing products mostly rely on the passive solution of fragrance masking, and cannot fundamentally decompose odor molecules from the chemical and biochemical levels, resulting in repeated odor in a short period of time, obvious reodor phenomenon, and difficulty in achieving long-term deodorization. Further analysis of various functional products shows that although chemical oxidants (such as hypochlorite and peroxide) can quickly oxidize some sulfur and nitrogen odor molecules, their strong corrosive and irritating nature not only may damage the surface of the home, but also poses a safety hazard for pets to lick; microbial preparations highly depend on the activity of live bacteria, have poor adaptability to temperature and humidity conditions, and have a long period of effect, which cannot meet the immediate deodorization demand; the core function of surfactant type cleaners is focused on stain removal, lacking deodorizing ability, and even in low pollution load scenarios, it is also difficult to maintain stable and long-term odor control effect. It can be seen that the existing technology needs to be improved.

BRIEF DESCRIPTION OF DRAWINGS
[0014] Figure 1 It is a schematic diagram of urease inhibition synergistic mechanism of the present application.
[0015] Figure 2 It is a schematic diagram of soybean saponin micelle structure. DETAILED DESCRIPTION
[0016] The present application provides a pet deodorant and a preparation method thereof. In order to make the purpose, technical scheme and effects of the present application more clear and explicit, the present application is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.
[0017] The present application provides a pet deodorant, and the preparation raw materials thereof include, by mass percentage, yucca extract 0.1-2%, fumaric acid 0.05-0.3%, lemon extract 0.1-2%, soybean saponin 0.3-2%, eucalyptus oil component 0.05-0.3%, antioxidant 0.05-0.2%, and the balance is water.
[0018] In the above components, the yucca extract contains yucca saponin, and the polysaccharide / saponin structure in the yucca saponin can have hydrophobic-hydrogen bond complexation with the active center of urease, and the micro-acidic microenvironment formed by the yucca saponin and fumaric acid can induce the conformational change of urease, thereby double inhibiting the urease activity and significantly reducing the generation of NH3. The lemon extract contains active ingredients such as citric acid, limonene, and polyphenols, which can have acid-base neutralization, oxidation-reduction or addition reactions with common odor molecules (such as ammonia, hydrogen sulfide, formaldehyde, etc.). The polysaccharides, plant proteins and surfactants in the lemon extract can wrap or adsorb odor molecules through van der Waals force, hydrogen bond and adsorption, thereby reducing their concentration in the air. Please refer to Figure 2Soyasaponin has both hydrophobic pentacyclic triterpene skeleton and hydrophilic sugar chain, the hydrophobic skeleton is self-aggregated to avoid water, and the sugar chain is outward, which can form spherical micelles instantly when preparing deodorant, the hydrophobic inner core can wrap eucalyptus oil components to form stable and transparent microemulsion. The terpene components in eucalyptus oil components show inhibitory effect on gram-positive or negative bacteria, yeast and dust mites. Antioxidants are used to inhibit component peroxidation and color change, and prolong shelf life.
[0019] Preferably, the eucalyptus oil component is selected from one or both of Eucalyptus globulus oil and Eucalyptus citriodora oil. Eucalyptus globulus oil contains 1,8-eucalyptol, which is a monoterpene oxide that can destroy the cell membrane of bacteria, leading to leakage of cell contents, thereby inhibiting or killing bacteria, especially gram-positive bacteria and some gram-negative bacteria. The core active ingredient of Eucalyptus citriodora oil is citronellal and a small amount of monoterpene (such as limonene), citronellal can not only destroy microbial cell membranes, but also interfere with their enzyme systems and metabolic processes, in addition to inhibiting bacteria, it also has effects on fungi and some insects.
[0020] Preferably, the antioxidant is selected from one or both of tea polyphenols and vitamin E.
[0021] The second aspect of the present application provides a preparation method of a pet deodorant, which is used to prepare the pet deodorant as described above, comprising the following steps: S01. Fumaric acid and Yucca extract are sequentially added in sterilized deionized water, and stirred for 5-15 min until completely dissolved; fumaric acid and Yucca extract are both water-soluble components, which can be directly dissolved in the water phase at the beginning to avoid uneven dispersion when mixed with oily components due to solubility differences; S02. The temperature is raised to 50℃, and soyasaponin is added under homogenization conditions for 5-15 min to form micelles; the temperature of 50℃ can improve the solubility of soyasaponin, so that it can be quickly dispersed, and the homogenization condition can provide high shear force to promote the hydrophilic group of soyasaponin to face the water phase and the hydrophobic group to aggregate, forming a stable micelle structure; S03. The temperature is cooled to 30℃, and the eucalyptus oil component is added, and stirred for 10-20 min to complete the solubilization; 30℃ is close to room temperature, which can avoid high temperature damage to the activity of the eucalyptus oil component, while ensuring that the micelles formed by the stable soyasaponin micelles can wrap the eucalyptus oil component, uniformly disperse the water-insoluble oily substances in the water phase, realize the solubilization of the oil phase, and ensure that the deodorant active ingredients exist stably in the product; S04. Add antioxidant and lemon extract, stir until uniform, and adjust pH to 4.5-5.5 to obtain the pet deodorant. The antioxidant and lemon extract are added last to minimize oxidation during the previous high-temperature processes. The pH is stabilized in the range of 4.5-5.5 to ensure the stability of the components (e.g., soy saponin micelles, yucca extract).
[0022] Preferably, the method for preparing the pet deodorant further comprises S05: filtering the pet deodorant with a 0.22 μm microporous filter and filling the product under the protection of inert gas.
[0023] Preferably, the method for preparing the pet deodorant further comprises S06: sterilizing the filled product by gamma ray or electron beam irradiation.
[0024] The present application uses scalable aqueous process, low-temperature homogenization and irradiation sterilization, and the equipment is versatile and cost-controllable. The raw materials are of natural origin or food grade, meeting the safety requirements for pet licking.
[0025] The present application also provides a deodorizing granule, which is prepared from the following raw materials: a solid carrier and the pet deodorant as described above. The solid carrier can be a zeolite granule or other solid carrier with adsorption function. The pet deodorant can be sprayed on the solid carrier, and the deodorizing granule is obtained after drying.
[0026] The present application is further illustrated by the following specific examples and comparative examples.
[0027] Example 1 A pet deodorant is prepared from the following raw materials by mass percentage: 0.5% yucca extract, 0.1% fumaric acid, 0.5% lemon extract, 2.0% soy saponin, 0.15% eucalyptus oil, 0.1% tea polyphenol, and the balance being water; The eucalyptus oil is blue eucalyptus oil; and the antioxidant is tea polyphenol. The lemon extract and yucca extract are purchased from Shaanxi Muyun Biotechnology Co., Ltd. The method for preparing the pet deodorant comprises the following steps: S01. Sterilize the deionized water at 121℃ for 15 min and cool to ≤40℃; S02. Add fumaric acid and yucca extract in sequence, and stir for 5-15 min to dissolve; S03. Increase the temperature to 50℃, and add soy saponin under homogenization conditions to form micelles for 5-15 min; S04. Cool to 30℃, add eucalyptus oil, and stir for 15 min to complete the solubilization; S05. Add antioxidant and lemon extract, adjust pH to 4.8 with food-grade acidity regulator; S06. After 0.22 μm microfiltration, fill under inert gas protection; S07. Obtain finished product by electron beam irradiation sterilization. The pet deodorant is a light yellow transparent liquid with micellar particle size <100 nm.
[0028] Example 2 A pet deodorant, which differs from Example 1 in that the content of Yucca extract in the formula is 1%, and the content of fumaric acid is 0.05%.
[0029] Example 3 A pet deodorant, which differs from Example 1 in that the content of Yucca extract in the formula is 0.5%, and the content of fumaric acid is 0.2%.
[0030] Example 4 A pet deodorant, which differs from Example 1 in that the terpenoid oily component of Eucalyptus teres is lemon eucalyptus oil, and the content is 0.15%, and the rest is the same as Example 1.
[0031] Example 5 A pet deodorant, which differs from Example 1 in that the content of the terpenoid oily component of Eucalyptus teres in the formula is 0.15%, which is composed of blue gum oil and lemon eucalyptus oil with a mass ratio of 0.7:1.
[0032] Example 6 A pet deodorant, which differs from Example 1 in that the antioxidant in the formula is vitamin E.
[0033] Comparative Example 1 A pet deodorant, which differs from Example 1 in that no fumaric acid is added in the formula.
[0034] Comparative Example 2 A pet deodorant, which differs from Example 1 in that no Yucca extract is added in the formula.
[0035] Comparative Example 3 A pet deodorant, which differs from Example 1 in that no lemon extract is added in the formula.
[0036] I. Test the deodorizing performance of the pet deodorants prepared in the above examples and comparative examples. Referring to GB / T 33610.2-2017, static deodorizing experiments are carried out in a small sealed cabin, the initial ammonia concentration is 40 ppm, and the residual ammonia concentration is measured 24 h after spraying 1 mL of sample. The results are shown in Table 1.
[0037] Table 1
[0038] From the above results, it can be seen that the ammonia removal rate of Example 1 is the highest, followed by Example 5 and Example 6. Specifically, comparing Examples 1, 2 and 3, Example 1 has the best deodorizing effect, indicating that the ratio of fumaric acid to yucca extract affects the deodorizing effect, and the optimal ratio of fumaric acid to yucca extract is screened and optimized by the present application. The ammonia removal rates of Comparative Examples 1 and 2 are greatly reduced compared to Example 1, verifying the synergistic effect of fumaric acid and yucca extract. The ammonia removal rate of Comparative Example 3 is also greatly reduced compared to Example 1, indicating that lemon extract also plays a key role in deodorization. The results of Examples 4 and 5 show that eucalyptus oil has better deodorizing effect than lemon eucalyptus oil, and considering the pungent smell of lemon eucalyptus oil, blue gum oil is preferred.
[0039] II. Bacteriostatic test Method: According to standard WS / T 650-2019, the original solution was acted for 3 min, the bacteriostatic effect was detected, and the strains included Staphylococcus aureus ATCC6538, Escherichia coli 8099, Microsporum canis BNCC259680, and Pityrosporum ovale ATCC44344. The results are shown in Table 2.
[0040] Table 2
[0041] From the above results, it can be seen that: the bacteriostatic effects of Examples 1, 4 and 5 can all reach the standard, and the bacteriostatic rates of the four common pet bacteria are >99.99%. It shows that the two eucalyptus leaf terpene oil components in the system have good bacteriostatic performance.
[0042] III. Mite removal test Method: According to Q / CTI LD-SHPHCD-1437, after dilution of the sample, the number of surviving mites was counted after 20 min, and the results are shown in Table 3.
[0043] Table 3
[0044] From the above results, it can be seen that the mite removal rates of the deodorants of Examples 1, 4 and 5 are all above 99%.
[0045] The following further takes the deodorant prepared in Example 1 for other performance tests.
[0046] IV. Stain removal test Method: According to QB / T 4532-2013 Appendix A standard artificial soil smear, after cleaning, the results were calculated by weighing, and the results are shown in Table 4.
[0047] Table 4
[0048] As can be seen from the results in Table Four, the deodorant of Example 1 has good decontamination power.
[0049] V. Safety Evaluation
[0050] Table Five
[0051] As can be seen from the results in Table Five, the pet deodorant prepared in Example 1 of the present application has safety, no irritation to pet skin, and no toxicity to pets.
[0052] VI.

[0054] 6.2 Light irradiation discoloration experiment Test conditions: sample was placed in a colorless PET bottle and placed in direct sunlight at the window edge for continuous irradiation for 30 days, and samples were taken at 0, 5, 10, 20, 30 days for colorimetric determination (color difference meter); Results: ΔE <0.5 (determination threshold: ΔE≤1.0 for no discoloration).
[0055] 6.3 28-day preservative challenge experiment According to GB 4789.2-2022 and ASTM E640, the test bacterial solution was a self-inoculated mixed bacterial suspension (Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, Aspergillus niger, each 10 5 ~10 6 CFU / mL), samples were taken at 0, 3, 7, 14, 21, 28 days for counting, and the results are shown in Table Six.
[0056] Table Six
[0057] From the results of Table Six, it can be seen that the present formulation can meet the 28-day preservation challenge without the addition of traditional preservatives (such as sodium benzoate, MIT), relying only on pH buffering with fumaric acid, antioxidant with tea polyphenol, and bacteriostatic with terpenes, thereby meeting the safety requirements for pet licking.
