Description

Technical Field

[0001] This invention relates to the field of pet care technology, specifically to a method for preparing a cat litter deodorizer. Background Technology

[0002] Different types of cat litter have varying absorbency and clumping properties, which directly affect their odor control. For example, bentonite cat litter clumps well but produces more dust; tofu cat litter is environmentally friendly but gets wet easily. Humid weather makes cat litter smell worse because high humidity accelerates bacterial growth and ammonia release. Furthermore, poor ventilation exacerbates odor buildup. A cat's elimination habits also influence the litter's odor. If a cat hasn't developed good elimination habits, such as relieving itself on the edge of the litter box, the litter won't effectively trap feces, increasing the smell.

[0003] There are various cat litter deodorizing products on the market, but not all products are suitable for every type of cat litter. For example, some deodorizers work for certain types of cat litter but may disrupt the clumping ability of other types. Even with good cat litter and deodorizing products, odor can quickly accumulate in the litter box if feces and urine clumps are not cleaned promptly. Cat litter odor control is a common problem, especially for multi-cat households or households with limited living space.

[0004] Therefore, for most families, a highly effective, long-lasting, broad-spectrum, and non-irritating cat litter deodorizer is undoubtedly essential.

[0005] This invention fills this gap, offering a cat litter deodorizer with strong, rapid, and long-lasting deodorizing activity. The induced zinc ions possess decomposition, oxidation, catalysis, complexation, and reduction properties. The deodorizer interacts with the reactants, altering the reaction pathway and lowering the activation energy of odor factors. Furthermore, the zinc ions in this deodorizer not only react with hydrogen sulfide and ammonia in odors but also with -NH, -COOH, and -SH molecules in cat litter bacteria, thereby disrupting bacterial cell structure, inhibiting reproduction, and killing bacteria and mold. The cat litter deodorizer exhibits excellent decomposition and adsorption properties, rapidly decomposing odor molecules such as hydrogen sulfide, ammonia, and methanethiol in cat litter and feces, altering their molecular structure, thus reducing the toxicity of pollutants and destroying their chemical structure. Summary of the Invention

[0006] The purpose of this invention is to provide a method for preparing a cat litter deodorizer to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides a method for preparing a cat litter deodorizer, comprising the following steps:

[0009] Sodium carboxymethyl cellulose was added to S01 amino acid chelated zinc and heated to 50℃~90℃ for 2h~5h to allow the sodium ions in sodium carboxymethyl cellulose to undergo a displacement reaction with the zinc ions in amino acid chelated zinc, generating a zinc carboxymethyl cellulose precursor solution. After cooling, the precursor solution was obtained.

[0010] Add diammonium hydrogen phosphate, wheat dextrin, plant extract, and deionized water to the SO2 precursor solution, stir for 2 to 5 hours at 65℃ to 90℃, and then cool to obtain a cat litter deodorizer.

[0011] Further, in step S01, the mass ratio of amino acid chelated zinc to sodium carboxymethyl cellulose is 100:1 to 50:1.

[0012] Furthermore, in step S02, the mass ratio of the precursor solution to diammonium hydrogen phosphate is 50:1 to 10:1.

[0013] Further, in step S02, the mass ratio of diammonium hydrogen phosphate, wheat dextrin, plant extract, and deionized water is 1–10: 0.1–1: 0.1–0.5: 88.5–98.8.

[0014] Furthermore, in step S02, the plant extract is one or more of Artemisia argyi plant extract and lemon plant extract.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] Zinc carboxymethyl cellulose (Zn-CMC) is a composite material that combines zinc with carboxymethyl cellulose. It possesses the properties of both carboxymethyl cellulose and zinc, and because zinc has broad-spectrum antibacterial activity, it can inhibit the growth of various bacteria. Zinc carboxymethyl cellulose can release zinc ions to exert deodorizing, antibacterial, and bacteriostatic effects, and is used to remove the diffusion of harmful odors caused by bacterial growth.

[0017] In step S01 of this invention, a displacement reaction occurs between sodium ions in sodium carboxymethyl cellulose and zinc ions in amino acid chelated zinc, allowing carboxymethyl cellulose and zinc ions to combine through new coordination bonds, forming a new and more stable chelate. This new combination allows for better utilization of the zinc ions. The interaction between the diammonium hydrogen phosphate, wheat dextrin, plant extracts, and zinc carboxymethyl cellulose added in this invention ensures more thorough and uniform dispersion in the product, giving it both rapid adsorption and long-lasting deodorization. Current related products on the market only offer simple deodorization, and the deodorization effect is poor and prone to recurrence. This invention, however, not only has a rapid deodorization effect but also a long-lasting deodorization effect, resulting in a better overall effect.

[0018] This invention provides a cat litter deodorizer that can quickly absorb and inhibit harmful odorous substances such as NH3, H2S, and amines, rapidly eliminating the odor of cat feces and other waste, inhibiting bacterial growth, purifying the environment, and reducing disease. This product is practically non-toxic, provides long-lasting deodorization, does not irritate mucous membranes, and forms a breathable film to protect the home environment for an extended period. It is a broad-spectrum, highly effective new type of cat litter deodorizer. Detailed Implementation

[0045] The cat litter deodorizers prepared in Examples 1-5 were tested, and the results are as follows:

[0046] Test Example 1

[0047] The deodorizing effect was evaluated using an olfactory test. This test method assesses the intensity and suitability of odors based on human sense of smell, measuring characteristic parameters of malodors, including olfactory threshold or concentration and perceived intensity. A 10-person olfactory testing group was formed, consisting of non-smokers aged 15-50 with normal olfactory senses. The effectiveness of cat litter treated with the deodorizing agents prepared in Examples 1-5 was evaluated using five indicators: significant (4-5 points), good (3-4 points), average (2-3 points), poor (1-2 points), and ineffective (0 points). Seven groups were formed, and the average score for each group was calculated. The best score was 5 points, and the worst was 0 points. Only indicators with more than 5 participants in each group were considered valid test results; otherwise, a re-evaluation was conducted. Specific results are shown in Table 1 below.

[0048] Table 1. Olfactory sensory evaluation results of the simulated cat litter deodorizer test.

[0049]

[0050] As shown in Table 1, the deodorizing agents prepared in Examples 1-4 generally performed well, while Example 5 showed the best results, effectively and quickly removing odors from cat litter.

[0051] Test Example 2

[0052] Five enclosed spaces were selected, each space being 2m in size. 3One bucket of odor-producing cat litter, weighing 8 kg, was placed in each space. The indoor temperature was controlled at 40-45℃. Five spaces were selected for odor testing using the cat litter deodorizer prepared in Examples 1-5. The cat litter deodorizer was sprayed directly onto the cat litter. After spraying, the concentrations of ammonia, hydrogen sulfide, methanethiol, and dimethyl sulfide in the room were measured every 5 days. Using a blank room as a control, the removal rates of ammonia, hydrogen sulfide, and odor concentrations were calculated. The monitoring period was 30 days. The specific results are shown in Table 2 below. The detection methods used included GB / T14678-1993 Air Quality - Determination of Hydrogen Sulfide, Methanethiol, and Dimethyl Sulfide - Gas Chromatography and GB / T14675-1999 Air Quality - Determination of Malodor - Three-Point Comparison Odor Bag Method.

[0053] Table 2 Results of the simulated cat litter deodorizer test

[0054]

[0055] As shown in Table 2, the deodorizing agents prepared in Examples 1-4 have a moderate deodorizing effect, while Example 5 has the best effect, and can quickly and efficiently deodorize and remove odors from cat litter.

[0056] The cat litter deodorizers prepared in Comparative Examples 1-5 were tested, and the results are as follows:

[0057] Test Example 3

[0058] The deodorizing effect was evaluated using an olfactory test. This test method assesses the intensity and suitability of odors based on human sense of smell, measuring characteristic parameters of malodors, including olfactory threshold or concentration and perceived intensity. A 10-person olfactory testing group was formed, consisting of non-smokers aged 15-50 with normal olfactory senses. After treating cat litter with noticeable odor with the deodorizing agent prepared in proportions 1-5, the effectiveness evaluation indicators were divided into five categories: significant (4-5 points), good (3-4 points), average (2-3 points), poor (1-2 points), and ineffective (0 points). A total of seven groups were formed, and the average score of each group was calculated. The best score was 5 points, and the worst score was 0 points. Only indicators with more than 5 participants in each group were considered valid test results; otherwise, a re-evaluation was conducted. Specific results are shown in Table 3 below.

[0059] Table 3. Olfactory sensory evaluation results of the simulated cat litter deodorizer test.

[0060]

[0061] As can be seen from the data in Table 3, the deodorizing effect of the cat litter deodorizers prepared in Comparative Examples 1-5 is generally poor. This is mainly due to the fact that less of the corresponding components were added during the preparation process, resulting in a poorer deodorizing effect on odorous cat litter compared with that in Table 1.

[0062] Test Example 4

[0063] Five enclosed spaces were selected, each space being 2m in size. 3 One bucket of odor-producing cat litter, weighing 8 kg, was placed in each space. The indoor temperature was controlled at 40-45℃. Five spaces were selected for odor control tests using the cat litter deodorizers prepared in Comparative Examples 1-5. The cat litter deodorizer was sprayed directly onto the cat litter. After spraying, the concentrations of ammonia, hydrogen sulfide, methanethiol, and dimethyl sulfide in the rooms were measured every 5 days. Using a blank room as a control, the removal rates of ammonia, hydrogen sulfide, and odor concentrations were calculated. The monitoring period was 30 days. The specific results are shown in Table 4 below. The detection methods used included GB / T14678-1993 Air Quality - Determination of Hydrogen Sulfide, Methanethiol, and Dimethyl Sulfide - Gas Chromatography and GB / T14675-1999 Air Quality - Determination of Malodor - Three-Point Comparison Odor Bag Method.

[0064] Table 4 Results of the simulated cat litter deodorizer test

[0065]

[0066] As shown in Table 4, the deodorizing effects of the cat litter deodorizers prepared in Comparative Examples 1-5, such as removing toxic and harmful gases like ammonia and hydrogen sulfide, are not ideal. This is mainly due to the insufficient addition of certain components during the preparation process, hence the significant difference in overall deodorizing effect compared to Table 2.
