Description

Technical Field

[0001] This invention belongs to the interdisciplinary field of materials chemistry and environmental governance. Specifically, it relates to a plant-based deodorizing agent formula and its standardized configuration method that uses natural plant extracts as the core raw material to achieve deodorization without secondary pollution by decomposing malodor molecules in a targeted manner. It is particularly suitable for malodor pollution control in scenarios such as livestock breeding, waste disposal, and public environments. Background Technology

[0002] With the continuous improvement of global awareness of ecological and environmental protection, odorous gas pollution has become the fourth largest environmental hazard after air, water, and soil pollution, seriously threatening human health and ecological balance. Common odorous gases mainly include volatile organic and inorganic compounds such as ammonia, hydrogen sulfide, methanethiol, and dimethyl sulfide, which are widely produced in pig farms, chicken farms, landfills, sewage treatment plants, public restrooms, etc. They not only cause sensory discomfort, but long-term exposure can also lead to respiratory diseases, nervous system damage, and other health problems, while also damaging the surrounding ecological environment.

[0003] Currently, mainstream deodorization technologies in the market are mainly divided into three categories: chemical deodorization, biological deodorization, and physical masking deodorization. All three have insurmountable technical defects and cannot meet the demands for efficient, safe, environmentally friendly, and stable deodorization. Chemical deodorizers use inorganic acids, alkalis, oxidants, and other chemical reagents as core components, achieving deodorization through oxidation-reduction and neutralization reactions. They have the advantages of low cost and rapid effectiveness, but chemical residues can easily cause secondary pollution of soil and water bodies, and have a strong irritating odor, corrosive to human skin, mucous membranes, and animal respiratory tracts. Some chemical components also pose carcinogenic and teratogenic risks, which is inconsistent with the trend of green and environmentally friendly development. Biological deodorizers use beneficial microorganisms such as photosynthetic bacteria, lactic acid bacteria, and Bacillus as active ingredients, decomposing malodorous substances through microbial metabolism. They are environmentally friendly and residue-free, but have drawbacks such as slow effectiveness, demanding cultivation conditions, poor environmental adaptability, and inability to increase concentration. Microorganisms are easily inactivated in extreme environments such as low temperature, high temperature, and high salinity, resulting in a significant reduction in deodorization effect. Furthermore, their production costs are high, making large-scale industrial application difficult. Physical masking deodorizers mainly consist of ether, artificial fragrances, and aromatic compounds. They only mask odors by smelling them, but cannot break down odor molecules at the source. The odor returns after a short period of masking, and the artificial fragrances and ethers are volatile and can have an inhibitory effect on the human central nervous system. Long-term use poses health risks.

[0004] Existing plant-based deodorizers are mostly compound products of plant extracts and chemical reagents, not pure plant components, and still contain residual chemical additives, failing to completely solve the problem of secondary pollution. Some pure plant-based deodorizers have unreasonable formulations, poor synergistic effects of components, low deodorization efficiency, and lack standardized temperature, speed, and time control in their preparation processes, resulting in poor product stability, easy stratification, coagulation, and precipitation, and short shelf life, failing to meet the needs of industrial production and long-term use. Therefore, developing a plant-based deodorizing agent that is purely plant-derived, highly efficient in decomposing malodors, safe and non-irritating, highly stable, and free from secondary pollution has become an urgent technical challenge to be solved in the fields of materials chemistry and environmental governance. Summary of the Invention

[0005] To address the shortcomings of existing technologies such as secondary pollution from chemical deodorization, slow effectiveness and poor stability of biological deodorization, inability of physical masking to completely eliminate odors, and the presence of residual chemicals and insufficient product stability in plant-based deodorizers, this invention provides a plant-based decomposition deodorizer formula and preparation method. Using pure plant extracts as the sole raw material, through scientific formulation and precise process control, it achieves efficient capture, decomposition, and oxidation of malodorous gases such as ammonia, hydrogen sulfide, methanethiol, and dimethyl sulfide, eliminating odors at their source. It also possesses the technical advantages of being safe and antibacterial, non-irritating, highly stable, environmentally friendly, and residue-free, thus solving the core pain points of traditional deodorization technologies.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] I. Formula Composition (by weight)

[0008] A plant-based deodorizing agent comprises the following raw material components in parts by weight:

[0009] The formula contains 60-95 parts tea polyphenol extract, 40-60 parts grape seed extract, 120-180 parts yucca extract, 10-30 parts eucalyptus oil, 45-75 parts oxalis extract, 12-30 parts gardenia essential oil, 16-32 parts rose essential oil, 8-15 parts peppermint essential oil, and 480-700 parts deionized water. All ingredients are natural plant extracts or extracts, free from any chemically synthesized additives, preservatives, oxidants, or pH adjusters, achieving a pure plant-based green formula.

[0010] II. Mechanism of Action of Each Component

[0011] 1. Yucca extract: The core deodorizing component, it has a specific targeted decomposition ability, can accurately bind to the molecular structure of ammonia and hydrogen sulfide, destroy their malodorous groups, and achieve decomposition from the source. At the same time, it has a strong adsorption capacity, quickly captures malodorous molecules in the air, and improves the deodorization rate.

[0012] 2. Tea polyphenol extract: Rich in polyphenolic active substances, it can neutralize alkaline odor molecules, inhibit the reproduction of odor-producing microorganisms, reduce the generation of odorous gases, and at the same time have antioxidant effects, extend the shelf life of products, and improve product stability.

[0013] 3. Grape seed extract: Contains a high concentration of proanthocyanidins, which work synergistically with tea polyphenols to enhance the antibacterial effect, prevent product deterioration, and help decompose organic odor molecules, thus improving the overall deodorization effect.

[0014] 4. Oxalis extract: A natural plant active ingredient that can decompose sulfur-containing organic malodorous gases such as methanethiol and dimethyl sulfide, making up for the insufficient ability of yucca extract to decompose organic sulfur compounds and achieving full coverage of all types of malodors.

[0015] 5. Eucalyptus oil and peppermint essential oil: These are natural volatile plant essential oils that, when atomized, can physically encapsulate odor molecules, temporarily masking unpleasant smells. They also have natural antibacterial properties, inhibiting bacterial growth, and are mildly volatile with no irritating odor.

[0016] 6. Gardenia essential oil and rose essential oil: Provide natural plant fragrance, leaving a light floral scent after deodorizing, enhancing the user experience, while also synergistically enhancing antibacterial effects, stabilizing the product system, and preventing stratification and sedimentation.

[0017] 7. Deionized water: As a dispersion medium, it ensures uniform mixing of plant extracts without interference from impurities, thereby improving product transparency and stability.

[0018] III. Configuration Method

[0019] The formulation method of this invention achieves thorough emulsification and uniform mixing of each component by precisely controlling temperature, stirring speed, reaction time, and feeding sequence, thus ensuring product stability and deodorizing activity. The specific steps are as follows:

[0020] 1. Preparation of base solution: Inject the prescribed amount of deionized water into the reactor, turn on the heating device, and heat the water temperature to 80℃ at a uniform rate. Through the reactor constant temperature control system, maintain the water temperature at 80℃±1℃ to avoid temperature fluctuations affecting the activity of the components.

[0021] 2. Dissolving the core extract: Slowly add the prescribed amount of yucca extract to deionized water at a constant temperature of 80℃ while turning on the stirrer. Control the stirring speed to 120-180 rpm and stir for 10 minutes until the yucca extract is completely dissolved and there are no particles left.

[0022] 3. Addition of auxiliary extracts: Add the formulated amounts of oxalis extract, grape seed extract, and tea polyphenol extract to the reactor in sequence. After each addition of raw material, maintain a constant temperature of 80°C and a stirring speed of 120-180 rpm for 10 minutes to ensure that each component is fully dissolved and initially mixed in sequence.

[0023] 4. Plant essential oil emulsification: Add the prescribed amount of eucalyptus oil to the reaction vessel, maintain a constant temperature of 80℃, adjust the stirring speed to 240-300 rpm, and stir at high speed for 20 minutes to achieve full emulsification of eucalyptus oil and aqueous system; then add gardenia essential oil, rose essential oil, and peppermint essential oil in sequence. Repeat the above high-speed emulsification steps for each essential oil added to ensure uniform dispersion of essential oil.

[0024] 5. Fully react and mature: After all raw materials have been added, continue to maintain a constant temperature of 80℃ and a stirring speed of 240-300 rpm for 60 minutes to allow the components to work synergistically and form a stable homogeneous system.

[0025] Cooling and Packaging: The material in the reactor is naturally cooled to room temperature (25℃±2℃), and a quality self-inspection is carried out. The test indicators include appearance, transparency, odor, and active ingredient content. After passing the self-inspection, it is packed into barrels and sealed for storage, thus obtaining the finished plant decomposition deodorant.

[0026] The beneficial effects of this invention are:

[0027] (1) All raw materials are natural plant extracts, without any chemical synthetic reagents, non-irritating, non-corrosive, and non-polluting. They are friendly to humans, animals, plants and the environment and can be directly used in sensitive scenarios such as animal husbandry and food processing. Highly efficient decomposition and root-cause deodorization: Through the synergistic effect of multiple components, it can capture, decompose and oxidize malodorous gases such as ammonia, hydrogen sulfide, methanethiol and dimethyl sulfide, rather than physically masking them. The deodorization is thorough and there is no repeated odor.

[0028] (2) Standardized process control ensures that the product is uniform, transparent, without layering, condensation, or sedimentation. It can be stored at room temperature for more than 6 months without deterioration and its deodorizing activity does not decrease. It has a wide range of applications: it can be widely used in pig farms, chicken farms, landfills, sewage treatment plants, public restrooms, pet residences and other scenarios. It adapts to different environmental temperature and humidity conditions and has no environmental limitations.

[0029] (3) The components such as tea polyphenols, grape seed extract, and plant essential oils work together to inhibit bacteria, reduce the growth of odor-producing microorganisms, and inhibit the generation of malodorous gases from the source, thus achieving the dual effects of deodorization and antibacterial action.

[0076] Performance testing

[0077] The deodorizers obtained in Examples 1-3 and Comparative Examples 1-9 were applied to a simulated pig farm environment. The concentrations of ammonia, hydrogen sulfide, methanethiol, and dimethyl sulfide before and after deodorization were detected by gas chromatography, and the removal rate was calculated. At the same time, the appearance of the products was observed and the stability was evaluated.

[0078] The specific testing methods are as follows, following the relevant standards of GB / T 14675-1993 "Determination of Odor in Air Quality - Three-Point Comparison Odor Bag Method", GB / T 18883-2002 "Indoor Air Quality Standard" and HJ 583-2010 "Determination of Benzene Series Compounds in Ambient Air - Solid Adsorption / Thermal Desorption - Gas Chromatography" to ensure that the test data are true, accurate and repeatable.

[0079] Sample pretreatment: The deodorant products obtained from each example and comparative example were placed at room temperature (25℃±2℃) for 24 hours to ensure that the samples were uniform, without layering or condensation; 10.000g of sample was accurately weighed using an electronic balance and placed in a 100mL volumetric flask, deionized water was added to the mark, and the mixture was shaken well to obtain a sample dilution solution (diluted 10 times) for later use; at the same time, a blank control group was set up, which was deionized water, also diluted 10 times, for later use.

[0080] Simulation test chamber environment setting

[0081] 1. Environmental parameter control: Adjust the temperature in the simulation test chamber to 25℃±1℃, the relative humidity to 60%±5%, and the wind speed to 0.3m / s. Seal the test chamber, turn on the stirring device, and stabilize for 2 hours to ensure that the environment inside the chamber is uniform and odorless, and that the concentrations of ammonia, hydrogen sulfide, methanethiol, and dimethyl sulfide in the air are all below the detection limits (ammonia ≤0.01μL / L, hydrogen sulfide ≤0.005μL / L, methanethiol ≤0.001μL / L, dimethyl sulfide ≤0.001μL / L).

[0082] 2. Odor Gas Injection: Using a micro-syringe, inject ammonia, hydrogen sulfide, methanethiol, and dimethyl sulfide standard stock solutions into the simulated test chamber to achieve the initial concentrations of each odor gas in the chamber that simulate the actual odor concentrations in a pig farm (ammonia 500 μL / L, hydrogen sulfide 100 μL / L, methanethiol 50 μL / L, dimethyl sulfide 30 μL / L). After injection, continue stirring for 30 minutes to ensure that the odor gases are evenly distributed in the chamber. At this time, collect gas samples from the chamber as samples before deodorization.

[0083] Deodorization treatment and sample collection

[0084] 1. Deodorant spraying: Using a sprayer, evenly spray the pretreated sample dilution into the simulated test chamber (spraying amount is 0.5mL / m³, that is, 0.5mL of diluted deodorant is sprayed per cubic meter of test chamber). During the spraying process, keep the spray uniform and avoid local concentrations that are too high or too low. After spraying, continue to seal the test chamber and maintain stirring to ensure that the deodorant is in full contact with the malodorous gas. The reaction time is controlled at 2 hours (meeting the deodorization time requirements of actual application scenarios).

[0085] 2. Sample Collection: After 2 hours of reaction, gas samples were collected from different locations (upper, middle, and lower layers, with 3 sampling points per layer) in the experimental chamber using an atmospheric sampler. 100 mL of gas was collected from each sampling point, injected into a sampling bag, and marked. At the same time, gas samples were collected from the experimental chamber of the blank control group, following the same procedure. All samples were immediately sent to the testing laboratory after collection and tested within 2 hours to avoid detection errors caused by the volatilization of gas components.

[0086] Gas chromatography detection procedure

[0087] 1. Instrument calibration: Turn on the gas chromatograph, preheat for 30 minutes, and adjust the instrument parameters to their optimal state. The specific parameters are as follows:

[0088] Chromatographic column: packed column (material: stainless steel, size: 2m×3mm, stationary phase: GDX-102);

[0089] 2. Column temperature: Programmed temperature rise, initial temperature 50℃, hold for 3 min, then increase to 150℃ at a rate of 10℃ / min, hold for 5 min;

[0090] 3. Detector temperature: FID detector temperature 200℃, TCD detector temperature 180℃;

[0091] 4. Carrier gas: Nitrogen, flow rate 30 mL / min;

[0092] 5. Hydrogen flow rate: 40 mL / min;

[0093] 6. Airflow rate: 400 mL / min;

[0094] 7. Injection volume: 10 μL, injection method: manual injection, injection port temperature: 180℃.

[0095] 8. Standard Curve Preparation: Take ammonia, hydrogen sulfide, methanethiol, and dimethyl sulfide standard stock solutions and dilute them with anhydrous ethanol to prepare standard working solutions with different concentration gradients (ammonia: 10 μL / L, 50 μL / L, 100 μL / L, 300 μL / L, 500 μL / L; hydrogen sulfide: 5 μL / L, 20 μL / L, 50 μL / L, 80 μL / L, 100 μL / L; methanethiol: 1 μL / L, 10 ... μL / L, 30μL / L, 50μL / L, 80μL / L; methyl sulfide: 1μL / L, 5μL / L, 10μL / L, 20μL / L, 30μL / L); inject the standard working solutions of each concentration sequentially into the gas chromatograph, measure the peak area, plot the standard curve with the standard working solution concentration as the abscissa and the peak area as the ordinate, calculate the regression equation, and require a correlation coefficient R² ≥ 0.999 to ensure detection accuracy.

[0096] 9. Sample Detection: The collected gas samples before and after deodorization, as well as the blank control group sample, were sequentially injected into the gas chromatograph and detected according to the instrument parameters described above. The peak area of ​​each sample was recorded. The actual concentrations of ammonia, hydrogen sulfide, methanethiol, and dimethyl sulfide in each sample were calculated based on the regression equation of the standard curve. Each sample was tested in parallel three times, and the average of the three test results was taken as the final detection concentration to reduce detection error.

[0097] Removal rate calculation method

[0098] The formula for calculating the odor removal rate is as follows:

[0099] η = C0 − C1C0 × 100%

[0100] Where: η——Removal rate of a certain odorous gas (%); C0——Concentration of the odorous gas in the simulated test chamber before deodorization (μL / L); C1——Concentration of the odorous gas in the simulated test chamber after deodorization (μL / L); During the calculation, one decimal place is retained to ensure the accuracy of the calculation.

[0101] Product appearance and stability testing

[0102] 1. Appearance and condition inspection: Place the deodorant products obtained from each example and comparative example in a transparent glass container and observe the appearance, transparency, and whether there are phenomena such as layering, coagulation, and precipitation under natural light (without direct sunlight). Record the observations. At the same time, smell the samples to determine whether there are any irritating or unpleasant odors and evaluate the user experience.

[0103] 2. Stability Test: After sealing each sample, store it in a cool, ventilated place at room temperature (25℃±2℃). Observe the changes in the appearance of the samples after 1 month, 3 months, and 6 months of storage. At the same time, test the deodorization activity (i.e., removal rate of ammonia, hydrogen sulfide, methanethiol, and dimethyl sulfide) of the samples according to the gas chromatography detection method described above to determine whether the deodorization activity has decreased. If after 6 months of storage, the sample shows no stratification, no condensation, and no precipitation, and the deodorization activity decreases by no more than 5%, it is considered to be of good stability.

[0104] Requirements for blank control and parallel trials

[0105] 1. Blank control: A blank control group (deionized water dilution) is set up for each batch of tests. The test steps for the blank control group are exactly the same as those for the sample test. If the blank control group detects the concentration of malodorous gas, the blank value must be subtracted from the sample test results to ensure the accuracy of the test data.

[0106] 2. Parallel tests: Three sets of parallel tests were set up for each example and comparative sample. The formulation, preparation method and test conditions of the parallel tests were completely identical. The removal rate deviation of the three sets of parallel tests should not exceed 3%. Otherwise, the test should be repeated to ensure the repeatability and reliability of the test results.
