Description

Technical Field

[0001] The invention relates to a pet deodorant, a preparation method and application thereof. Background Art

[0002] In modern society, with the improvement of people's living standards and the change of ideas, pets have become an important member of more and more families, and the maintenance and living environment quality of pets have received widespread attention. Pets not only bring joy to the family, but also play an important role as a playmate and companion. However, while pets bring fun to people, there are also some troubles, especially the odor problem generated during the breeding process. These odors, such as the fishy smell of oil secreted by sweat glands and the odor of excrement, are not only uncomfortable, but may also contain a variety of harmful substances, posing a threat to the health of pet owners and pets themselves.

[0003] The individual odor of pets mainly comes from scent glands, saliva, urine and feces. The odor problem of pet excrement, especially the odor caused by the decomposition of urine and feces, has become a major challenge in pet care. These odors not only directly affect the living environment of pet owners, but may also have a negative impact on the health and well-being of the pets themselves. Especially in closed or poorly ventilated indoor environments, the odor problem is more prominent. Long-term exposure to such an environment may cause health risks to both pets and humans.

[0004] The odor of pet excrement mainly comes from the decomposition process of organic matter in it under the action of microorganisms. These organic substances, such as proteins, amino acids and fatty acids, produce a variety of foul-smelling gases under the action of bacteria, including ammonia, hydrogen sulfide, methyl mercaptan and methyl sulfide. The generation of these gases is not only related to the chemical composition of pet excrement, but also affected by many factors, such as the pet's diet, health status and excrement disposal method.

[0005] Ammonia is a colorless, pungent gas that comes primarily from the decomposition of urea in pet urine. Hydrogen sulfide, a gas with a rotten egg smell, comes primarily from the decomposition of amino acids with a high sulfur content in pet feces. Methyl mercaptan and methyl sulfide are two of the more challenging malodorous substances that have strong and unbearable odors. Methyl mercaptan and methyl sulfide are particularly difficult to remove because although their concentrations in pet excrement are low, they can be detected by the human sense of smell even in trace amounts due to their low olfactory threshold. In addition, these sulfur-containing compounds are relatively stable chemically and are not easily removed by simple chemical reactions.

[0006] There are many kinds of pet deodorants on the market, but there are still problems such as poor effect and insufficient safety of ingredients. For example, Chinese invention patent CN107694327A discloses a biological deodorant and its use method, which includes EM compound beneficial bacteria, organic acids (such as maleic acid and itaconic acid), plant essences and bamboo acetic acid. Although this deodorant shows a certain effect in treating certain malodorous gases, it is not effective in removing specific malodorous substances such as methyl mercaptan and methyl sulfide.

[0007] In view of this, there is an urgent need to develop a new type of pet deodorant that can more effectively target difficult-to-remove malodorous substances such as methyl mercaptan and methyl sulfide. Summary of the invention

[0026] A pet deodorant comprises the following raw materials in percentage by weight: 0.5-1.5% of EM compound bacteria, 0.05-0.15% of vinylphosphonic acid, 0.06-0.16% of tea extract, 0.03-0.09% of deodorizing surfactant, 0.02-0.06% of chelating agent, and the balance is water.

[0027] The deodorizing surfactant is at least one of cetyltrimethylammonium bromide and soybean ethyl sulfate morpholine.

[0028] The chelating agent is at least one of ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, N-methylglycine diacetic acid (CAS No.: 29578-05-0), cyclic chelating agent 18-crown-6-ether (CAS No.: 17455-13-9) and cyclic chelating agent 15-crown-5-ether (CAS No.: 33100-27-5).

[0029] The preparation method of the pet deodorant comprises the following steps: adding EM compound bacteria, vinylphosphonic acid, tea extract, deodorizing surfactant and chelating agent into water, and stirring and mixing them evenly.

[0030] EM compound bacteria reduce the generation of malodorous substances by decomposing organic matter in pet excrement. They promote the growth of beneficial microorganisms and inhibit the activity of odor-causing microorganisms. The mechanism is as follows: EM compound bacteria produce substances that are beneficial to environmental improvement (such as organic acids, antibiotics, etc.) through their metabolic activities, thereby changing the structure of microbial communities and reducing the generation of malodorous substances.

[0031] Vinylphosphonic acid, as an organic acid, inhibits the growth of odor-causing microorganisms by adjusting the pH value. Its mechanism is: lowering the pH value of the environment, thereby adversely affecting those odor-causing bacteria that are more active in neutral or alkaline environments.

[0032] Tea extracts are rich in polyphenols, especially catechins, which play a vital role in the effectiveness of pet deodorants. These compounds not only have powerful antioxidant properties, but can also effectively neutralize and adsorb various malodor molecules. The basic structure of catechins is a di- (or ortho) phenol-based benzopyran derivative, which gives them significant deodorizing activity. In particular, the hydroxyl groups on the catechin ring, due to their strong polarity, can react with malodor molecules such as hydrogen sulfide to generate new odorless or low-odor compounds. In addition, these hydroxyl groups can also release hydrogen ions and combine with nitrogen atoms in ammonia to form ammonium salts, thereby effectively reducing the odor caused by ammonia. These characteristics make tea extracts an indispensable component in pet deodorants, improving their removal efficiency for various odor molecules.

[0033] Soybean ethyl sulfate morpholine, also known as soybean oil ethyl morpholine azotium ethyl sulfate, CAS number: 61791-34-2.

[0034] Both cetyltrimethylammonium bromide (CTAB) and soybean ethyl sulfate morpholine (FORESTALL) are effective deodorizing surfactants, but their mechanisms of action are not exactly the same. CTAB is mainly used as a surfactant and antibacterial agent, and its effect on deodorizing is different from that of FORESTALL.

[0035] CTAB acts as a surfactant that reduces the surface tension of water, helping to remove grease and dirt. This can reduce odors to a certain extent, as some odorous substances may be attached to grease. CTAB has antimicrobial properties and can inhibit the growth of certain microorganisms that may be one of the sources of malodor.

[0036] FORESTALL, as a special cationic surfactant, can reduce the concentration of odor molecules in the air by coordinating or neutralizing them, thus achieving the effect of removing odors. FORESTALL has good water solubility and a low active dosage, making it suitable for efficient odor removal.

[0037] It is unexpectedly found that the deodorant surfactant is better when it is compounded with hexadecyl trimethyl ammonium bromide and soybean ethyl sulfate morpholine. Specifically, the deodorant surfactant is composed of 2-4 parts by weight of hexadecyl trimethyl ammonium bromide and 6-8 parts by weight of soybean ethyl sulfate morpholine.

[0038] In the pet deodorant of the present invention, chelating agents play a major role. By forming stable complexes with metal ions (such as calcium, magnesium, iron, etc.) in water, chelating agents significantly reduce the free concentration of these metal ions. This process is crucial for controlling the odor in pet excrement because certain metal ions are essential factors for the growth and metabolism of microorganisms, especially those that produce malodors. By limiting the availability of these key metal ions, chelating agents indirectly inhibit the activity of these odor-causing microorganisms, thereby reducing the production of malodorous substances. In addition, chelating agents can also prevent the production of metal-catalyzed odors. In some cases, the formation of malodorous substances may be caused by chemical reactions catalyzed by metal ions. By binding to these metal ions, chelating agents effectively prevent them from participating in such reactions, further reducing the generation of malodorous substances.

[0087] Test Example 1:

[0088] The performance of biological deodorants in accordance with 6.19 in "CJ / T 516-2017 Technical Requirements for Domestic Waste Deodorants" was tested. The test results are shown in the table below.

[0089]

[0090] In the pet deodorant of the present invention, Example 1 uses vinylphosphonic acid as an organic acid, while Comparative Examples 1 and 2 use a compound of maleic acid and itaconic acid and wood acetic acid as organic acids, respectively. Example 1 shows a higher deodorization efficiency than Comparative Examples 1 and 2. As an organic acid, vinylphosphonic acid inhibits the growth of odor-causing microorganisms by lowering the pH value of the environment. This has an adverse effect on those odor-causing bacteria that are more active in neutral or alkaline environments. This means that vinylphosphonic acid can more effectively control the activity of odor-causing microorganisms, thereby reducing the generation of malodorous substances. Although maleic acid, itaconic acid and wood acetic acid are also organic acids, their effect in adjusting pH values ​​may not be as strong as vinylphosphonic acid. In addition, these acids may not be as effective as vinylphosphonic acid in inhibiting odor-causing microorganisms. The use of vinylphosphonic acid in Example 1 may provide the deodorant with stronger antibacterial and pH adjustment capabilities, and the synergistic effect with other ingredients such as EM composite bacteria and tea extract enhances the control effect of malodor.

[0091] Different chelating agents were used in Examples 2-6, wherein Examples 5 and 6 used cyclic chelating agents (18-crown-6-ether and 15-crown-5-ether), while Examples 2, 3 and 4 used ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid and N-methylglycine diacetic acid as chelating agents, respectively. The test results show that Examples 5 and 6 are significantly more efficient than other examples in removing ammonia, hydrogen sulfide, methyl mercaptan and methyl sulfide. This phenomenon may be explained by the chemical properties and mechanism of action of chelating agents. Chelating agents are substances that can form stable complexes with metal ions chemically. They reduce the concentration of metal ions through this complex reaction, thereby affecting metal-catalyzed chemical reactions, including those that produce odorous substances. Cyclic chelating agents such as 18-crown-6-ether and 15-crown-5-ether are a special class of chelating agents that have specific ring structures and can effectively "encapsulate" specific metal ions. This spatial structural matching makes them more efficient and specific when forming metal complexes. Although ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid and N-methylglycinediacetic acid can also form complexes with metal ions, their spatial structure and chelation efficiency may not be as good as those of cyclic chelators. This may be because cyclic chelators can provide more stable structures and stronger chelation when forming metal complexes, thereby more effectively inhibiting the generation of odor-causing substances. In terms of removing malodorous substances such as ammonia, hydrogen sulfide, methyl mercaptan and dimethyl sulfide, the choice of chelating agent has a significant impact on efficiency. Due to its special chemical structure and efficient chelation ability, cyclic chelating agents may more effectively control the generation process of malodorous substances that require the participation of metal ions, thereby improving the deodorization efficiency.

[0092] In Examples 6-8, the different choices of deodorizing surfactants have a significant impact on the deodorizing effect. The soybean ethyl sulfate morpholine used in Example 6 mainly reduces the concentration of malodorous substances through its good emulsification and dispersion effects, while the hexadecyltrimethylammonium bromide in Example 7 captures and isolates malodorous molecules through its strong adsorption and encapsulation capabilities. In Example 8, these two surfactants are combined in a mass ratio of 3:7. This combination gives full play to the synergistic effect of the two: soybean ethyl sulfate morpholine disperses the malodorous molecules in the aqueous phase through its emulsification effect, making it easier to be adsorbed and fixed by hexadecyltrimethylammonium bromide, thereby effectively reducing the concentration of difficult-to-remove malodorous molecules such as methyl mercaptan and dimethyl sulfide. This synergistic effect not only improves the overall efficiency of the deodorant, but also particularly enhances the removal ability of difficult-to-handle malodorous substances, achieving a more superior deodorizing effect.

[0093] Example 2 uses soybean ethyl sulfate morpholine as a surfactant, while comparative examples 3 and 4 use sodium dodecylbenzene sulfonate and dodecyl glucoside, respectively. Soybean ethyl sulfate morpholine has excellent hydrophilic and lipophilic properties, can effectively reduce the surface tension of water, enhance the dispersion and dissolution of malodorous substances, thereby improving the ability to capture and neutralize malodorous molecules. In addition, it may also form a microemulsion or complex to wrap up the malodorous molecules to prevent them from volatilizing. In contrast, sodium dodecylbenzene sulfonate, as an anionic surfactant, although it is effective in cleaning grease, may not be as effective as soybean ethyl sulfate morpholine in neutralizing malodorous molecules. Dodecyl glucoside, as a nonionic surfactant, although it can reduce surface tension, may also be inferior to soybean ethyl sulfate morpholine in wrapping and neutralizing malodorous molecules. Therefore, the selection of soybean ethyl sulfate morpholine in Example 2, due to its unique chemical properties and efficient ability to neutralize malodorous molecules, makes it significantly better than comparative examples 3 and 4 in deodorization effect.
