Description

Technical Field

[0001] The present invention belongs to the field of wet wipes, and in particular relates to a kitchen wet wipe compound composition, a preparation method and an application. Background Art

[0002] Existing kitchen wipes generally use spunlace non-woven fabric substrates (a blend of wood pulp, polyester or viscose fibers) impregnated with a cleaning solution containing surfactants, solvents, and antibacterial agents.

[0003] Typical ingredients include: Surfactants: primarily anionic (such as sodium dodecylbenzenesulfonate), combined with nonionic (such as fatty alcohol polyoxyethylene ether) to enhance detergency. Solvents: ethanol (3-10%) or propylene glycol (5-15%) to dissolve oils and fats, glycerin (2-5%) for moisturizing. Antibacterial agents: benzalkonium chloride (0.1-0.3%) or quaternary ammonium salts for chemical preservatives. Natural ingredients: green tea extract, lemon essential oil, etc. for added fragrance and antibacterial properties.

[0004] The kitchen wipes in the prior art have the following deficiencies: 1. Non-degradable substrates: Polyester fibers account for a high proportion, and landfill or incineration leads to microplastic pollution. Degradable substrates, such as 100% cellulose, are expensive, have a market penetration rate of less than 10%, and pose serious environmental problems. There are also risks of chemical residues: anionic surfactants (such as sodium dodecylbenzene sulfonate) may remain on the surface of kitchen utensils, posing a safety hazard when in contact with food.

[0005] 2. Insufficient cleaning power for heavy oil stains: Burnt oil stains, condensed fat, etc. need to be wiped repeatedly, and inorganic adsorbents such as diatomaceous earth may scratch the surface of the non-stick pan.

[0006] Poor moisture retention: The moisture evaporation rate of large-packaged wet wipes exceeds 30% within 1 hour after opening, which easily generates friction resistance when wiping.

[0007] Weak antibacterial effect: Chemical preservatives (such as sodium benzoate) lose their effectiveness after the wipes dry and cannot effectively inhibit bacterial growth.

[0008] 3. Irritation risk: High concentrations of anionic surfactants (>8%) may cause skin allergies, with 15% of users with sensitive skin complaining about them. Large packages of wet wipes can dry out and harden (residual moisture <50%) after being left standing, while the lower wipes become overly wet and drip, impacting the user experience.

[0009] More than 80% of the products have the same formula and lack application design for different scenarios. In view of the above shortcomings, there is an urgent need to provide a kitchen wipe compound composition to meet the kitchen wipe supplies in different scenarios in daily life. Summary of the Invention

[0010] The purpose of the present invention is to address the shortcomings of the prior art and propose a kitchen wipe compound composition, preparation method and application. The composition is produced through "two dipping and two rolling" and is used in kitchen wipes. Bio-based raw materials such as APG and bamboo fiber account for ≥ 60%, and phenoxyethanol replaces traditional formaldehyde-releasing preservatives. It is phosphorus-free, nitrogen-free, and APEO-free; it is close to human skin, avoiding irritation caused by excessive AES, suitable for direct contact with tableware and kitchen utensils, and non-corrosive to materials such as stainless steel, ceramics, and glass.

[0011] In order to achieve the above object, the present invention adopts the following technical solution: a kitchen wipes compound composition, characterized in that it comprises the following components in percentage by weight: 60-70 parts base liquid 6-12 parts surfactant 1.5-4.5 parts of oil absorbent 8.1-13.3 parts of moisturizer 0.6-1.3 parts of antibacterial agent 0.2-0.5 parts of synergist and 0.1-0.3 parts of preservatives.

[0012] As a further description of the above technical solution: the surfactant contains alkyl polyglycoside APG, fatty alcohol polyoxyethylene ether sodium sulfate AES and sodium α-olefin sulfonate.

[0013] As a further description of the above technical solution: the oil absorbent contains nano-porous diatomaceous earth and sodium polyacrylate.

[0014] As a further description of the above technical solution: the moisturizing agent is glycerin, propylene glycol and hyaluronic acid.

[0015] As a further description of the above technical solution: the antibacterial agents are benzalkonium chloride and citric acid.

[0016] As a further description of the above technical solution: the synergist is tea tree essential oil, and the preservative is phenoxyethanol.

[0017] As a further description of the above technical solution: the following components are included in weight percentage: 60-70 parts of deionized water, 3-5 parts of alkyl polyglycoside APG, 2-4 parts of fatty alcohol polyoxyethylene ether sulfate AES, 1-3 parts of sodium α-olefin sulfonate, 1-3 parts of diatomaceous earth, 0.5-1.5 parts of sodium polyacrylate, 5-8 parts of glycerin, 3-5 parts of propylene glycol, 0.1-0.3 parts of hyaluronic acid, 0.1-0.3 parts of benzalkonium chloride, 0.5-1.0 parts of citric acid, 0.2-0.5 parts of tea tree essential oil, and 0.1-0.3 parts of phenoxyethanol.

[0018] As a further description of the above technical solution: in terms of weight percentage, it includes the following components: 65 parts of deionized water, 4 parts of alkyl polyglycoside APG, 3 parts of fatty alcohol polyoxyethylene ether sulfate AES, 2 parts of sodium α-olefin sulfonate, 2 parts of diatomaceous earth, 1 part of sodium polyacrylate, 6 parts of glycerin, 4 parts of propylene glycol, 0.2 parts of hyaluronic acid, 0.2 parts of benzalkonium chloride, 0.8 parts of citric acid, 0.3 parts of tea tree essential oil, and 0.2 parts of phenoxyethanol.

[0019] A method for preparing a kitchen wipe compound composition is used to prepare the kitchen wipe compound composition, specifically comprising the following steps: Step 1: Diatomaceous earth pretreatment: Nano-grinding to a particle size of ≤5μm and surface hydroxyl modification to improve hydrophilicity and avoid agglomeration that affects oil absorption efficiency.

[0020] Step 2: Mixing order: first dissolve alkyl polyglycoside APG, fatty alcohol polyoxyethylene ether sulfate sodium AES, and α-olefin sulfonate sodium in 45-50℃ warm water, then add moisturizer and oil absorbent in sequence, and finally cool to below 30℃ and add antibacterial agent and essential oil.

[0021] Step 3: Non-woven fabric impregnation: Use "two dips and two rolls" and control the liquid absorption rate at 180-200% to ensure that the base liquid is evenly distributed and there is no penetration residue on the edge.

[0022] The invention discloses an application of a kitchen wet wipe compound composition, wherein the kitchen wet wipe compound composition is applied to kitchen wet wipes.

[0023] Due to the adoption of the above technical solution, the beneficial effects achieved by the present invention are: (1) The present invention uses bio-based raw materials such as APG and bamboo fiber, accounting for ≥60%, and phenoxyethanol to replace traditional formaldehyde-releasing preservatives. It is phosphorus-free, nitrogen-free, and APEO-free. (2) The present invention is close to human skin by having a weakly acidic pH (5-6), thus avoiding irritation caused by excessive AES. It has no allergic reaction after skin patch test and is suitable for direct contact with tableware and kitchen utensils. (3) The present invention is gentle and meets safety requirements for tableware cleaning. The antibacterial persistence of PHMB can still reach a 24-hour antibacterial rate of 98%, meeting the needs of daily use. DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The present invention is described in detail with the following examples: Example 1

[0026] A kitchen wipes composite composition, comprising the following components in percentage by weight: 60-70 parts base liquid 6-12 parts surfactant 1.5-4.5 parts of oil absorbent 8.1-13.3 parts of moisturizer 0.6-1.3 parts of antibacterial agent 0.2-0.5 parts of synergist and 0.1-0.3 parts of preservatives.

[0027] The surfactant includes alkyl polyglycoside APG, fatty alcohol polyoxyethylene ether sulfate sodium AES and sodium α-olefin sulfonate; the oil absorbent includes nano-porous diatomaceous earth and sodium polyacrylate; the moisturizer includes glycerin, propylene glycol and hyaluronic acid; the antibacterial agent includes benzalkonium chloride and citric acid; the synergist is tea tree essential oil; and the preservative is phenoxyethanol; the carrier of the composition of all ingredients is a non-woven fabric substrate, which can clean greasy places such as kitchens. Example 2

[0028] A kitchen wipes composite composition, comprising the following components in percentage by weight: wherein the non-woven fabric is weighed separately, Deionized water: 65 parts Alkyl glycoside: 4 parts Fatty alcohol polyoxyethylene ether sodium sulfate: 3 parts 2 parts of sodium α-olefin sulfonate Diatomaceous earth: 2 parts Sodium polyacrylate: 1 part Glycerin: 6 parts Propylene glycol: 4 parts Hyaluronic acid: 0.2 parts Benzalkonium chloride: 0.2 parts Citric acid: 0.8 parts Tea tree essential oil: 0.3 parts Phenoxyethanol: 0.2 parts.

[0029] This embodiment uses a 20g / m² blend of bamboo and / or cotton fibers. Natural fibers are biodegradable and offer significant environmental benefits. High porosity improves liquid absorption, enabling absorption of 15 times or more of its own weight. It is also friction-resistant and non-shedding, making it suitable for oily environments like kitchens.

[0030] Alkyl polyglycoside (APG) is an environmentally friendly detergent with excellent biodegradability and gentle grease emulsification. Sodium fatty alcohol polyoxyethylene ether sulfate (AES) is an anionic surfactant that effectively penetrates oil structures. When combined with APG, it creates a synergistic cleaning effect, reducing surface tension and facilitating grease removal. The nonionic surfactant (APG) is mild and environmentally friendly, but has moderate detergency, while the anionic surfactant (AES) has strong penetration but is highly irritating. Their combination maximizes the balance between detergency, mildness, and environmental performance.

[0031] In the specific implementation process, APG (non-ionic) and AES (anionic) are compounded, and the critical micelle concentration (CMC) is reduced by 30%, forming a more stable micelle structure, and the emulsification speed of stubborn oil stains, such as the pretreatment of coke scale on the bottom of the pot, is increased by 50%.

[0032] In the process of selecting and determining the ratio of alkyl polyglycoside APG and fatty alcohol polyoxyethylene ether sulfate sodium AES, we use synergistic decontamination experiments to determine: With the total surfactant concentration fixed at 7%, the APG:AES ratio was changed, such as 5:2, 4:3, and 3:4, to test the emulsification speed and residual amount of simulated kitchen grease, such as olive oil.

[0033] It was found that at 4:3, the surface tension dropped to 28mN / m (about 35mN / m for a single surfactant), the oil emulsification time was shortened by 40%, and there was no redness or swelling reaction in the skin irritation test.

[0034] Since AES easily generates the pollutant dioxin, the concentration needs to be controlled below 5%, and 3% was finally selected to ensure safety.

[0035] The oil absorbent contains nano-porous diatomaceous earth and sodium polyacrylate. Nano-porous diatomaceous earth adopts a physical oil absorption core, and its porous structure absorbs liquid oil to prevent the secondary spread of oil. Sodium polyacrylate is a highly absorbent resin, which adopts chemical oil absorption as an auxiliary. The polymer network locks the oil molecules, enhances the long-term oil absorption capacity, and also has a water retention function.

[0036] The specific working principle is: the porous structure of nano diatomaceous earth with a pore size of 5-10μm directly captures liquid oils, such as cooking oil and animal fats. The carboxylic acid group of sodium polyacrylate "anchors" the oil molecules through hydrogen bonding. The two work together to achieve rapid adsorption and thorough removal of heavy oil stains. After testing, the removal rate of solidified oil at 50°C is over 92%.

[0037] Our formula features a dual oil absorption mechanism through diatomaceous earth and sodium polyacrylate.

[0038] 1. Diatomaceous earth adopts nano-scale porous structure with pore size of 5-10μm to absorb liquid oil and fat, and can achieve physical adsorption: When the diatomaceous earth content is greater than 3%, the base liquid becomes thicker and tends to clog the pores of the non-woven fabric; When diatomaceous earth is less than 1%, the oil absorption capacity is insufficient; When the diatomaceous earth content is 2%, it is the porosity-adsorption capacity equilibrium value. In the specific implementation process, the experiment measured that the peanut oil adsorption capacity of diatomaceous earth at 2% is 5 times its own weight.

[0039] 2. Sodium polyacrylate uses a polymer resin to capture oil molecules through carboxylic acid groups, achieving chemical locking. A 1% sodium polyacrylate dosage can reduce residual oil in the base fluid by 60%, compared to a 30% reduction at 0.5% sodium polyacrylate. This also prevents excessive use from causing the wipes to become stiff. Testing has shown that a sodium polyacrylate dosage greater than 1.5% can reduce the flexibility of the wipes by 20%.

[0040] In this example, the specific ratio determination process was performed by fixing the other ingredients, setting the kitchen grease to lard, and the cleaning temperature to 30°C. The ratio of diatomaceous earth to sodium polyacrylate was varied to test the removal rate of solidified grease, such as lard. The test results showed that: In this formula, when the ratio of diatomaceous earth to sodium polyacrylate is 2:1, the removal rate reaches 92%. In the comparative test, comparative example 1: 2% diatomaceous earth, the removal rate is 75%; comparative example 2: 1% sodium polyacrylate, the removal rate is 60%. The specific test results are shown in Table 1 below: .

[0041] We use glycerin as the primary moisturizer, which absorbs and locks in moisture, keeping the wipes soft and moist, and preventing them from drying out and hardening. Propylene glycol acts as a secondary moisturizer, regulating base fluid viscosity and enhancing ingredient compatibility. Small molecule hyaluronic acid acts as a deep moisturizing factor, reducing water evaporation and enhancing the wipes' moist feel during use. This overall combination ensures long-lasting moisture and freshness.

[0042] During the specific experimental process, we selected the optimal ratio of glycerin to be 6%, propylene glycol to be 4%, and hyaluronic acid to be 0.2%.

[0043] When the main hygroscopic agent glycerol accounts for 5-8%, the moisture retention rate is greater than 80% after 7 days of storage at 45°C; When the proportion of glycerol, the main hygroscopic agent, is less than 5%, the water retention rate is less than 70% when stored at 45°C for 7 days; When the proportion of the main desiccant glycerin is greater than 8%, the base liquid viscosity is too high and is not suitable.

[0044] Please refer to Table 2 below for details: .

[0045] Therefore, in the formula of the present invention, we select 6% as the balance point between economy and effect.

[0046] In the selection process of propylene glycol: due to the viscosity of the base liquid, the best viscosity is 200-300m We have found through experiments that when the ratio of propylene glycol to glycerol is 1:1.5, the base fluid viscosity is 250m , neither dripping nor sticky.

[0047] Hyaluronic acid as deep moisturizing: small molecule hyaluronic acid can form a moisturizing film at 0.2% to reduce water evaporation. In a comparative test, when the hyaluronic acid is 0.1%, the moisturizing time can be extended by 3 days. Hyaluronic acid > 0.3% is excessive addition, which not only increases costs but also has no significant effect improvement.

[0048] For verification, we used a constant temperature and humidity chamber test at a temperature of 40°C and a relative humidity of 20%. We recorded the time it takes for the wipes to dry from opening. 6% glycerin, 4% propylene glycol, and 0.2% hyaluronic acid can achieve a moisturizing effect for 7 days, which is better than commercially available products with a moisturizing effect of 3 days.

[0049] The rational selection of the moisturizing agent in the present invention can achieve the following two effects: Three-dimensional moisturizing network: Glycerin, propylene glycol, and hyaluronic acid form a gradient moisturizing system. After storage testing at a high temperature of 45°C, the moisture retention rate of the wet wipes is ≥85% within 7 days after opening, avoiding the problem of traditional wet wipes being easy to dry out and harden.

[0050] Viscosity optimization: Propylene glycol adjusts the base fluid viscosity to 200-300m It can not only ensure that the non-woven fabric absorbs liquid evenly, but also avoid dripping during use, thereby improving the user experience.

[0051] In this embodiment, the antibacterial agents are benzalkonium chloride and citric acid, and the synergist is a natural extract of tea tree essential oil. Benzalkonium chloride is a broad-spectrum antibacterial agent that destroys bacterial cell membranes and effectively inhibits common kitchen bacteria such as Escherichia coli and Staphylococcus aureus. Citric acid has a natural antibacterial auxiliary effect, adjusting the pH to a weak acidity (pH 5-6), inhibiting bacterial growth, and softening scale. Tea tree essential oil is a natural antibacterial agent and also has odor-regulating properties. Tea tree essential oil contains terpenoid compounds that inhibit bacteria and impart a fresh smell instead of chemical flavors.

[0052] In this embodiment, 0.2% benzalkonium chloride can achieve a sterilization rate of ≥99% within 5 minutes, citric acid at pH 5.5 can inhibit fungal growth, and tea tree essential oil can enhance natural antibacterial properties. The triple effects cover common kitchen pathogens, such as Salmonella and Aspergillus flavus.

[0053] Phenoxyethanol is used as a preservative, which complies with EU EC1223 / 2009 standards, inhibits microbial contamination, and does not release formaldehyde.

[0054] We tested our formula for oil removal rate, antibacterial duration, moisturizing days after opening, and environmental performance. We also compared our formula with commercially available products to demonstrate its superior practical performance. The results are shown in Table 3 below.

[0055] .

[0056] Therefore, the kitchen wipes composite composition described in the present invention can achieve the following beneficial effects: (1) Bio-based raw materials such as APG and bamboo fiber account for ≥60%. Phenoxyethanol replaces traditional formaldehyde-releasing preservatives and is phosphorus-free, nitrogen-free, and APEO-free.

[0057] (2) pH is weakly acidic (5-6) and close to human skin, avoiding irritation caused by excessive AES. It has no allergic reaction after skin patch test and is suitable for direct contact with tableware and kitchen utensils.

[0058] (3) No corrosion to materials such as stainless steel, ceramics, and glass.

[0059] Example 3 In this example, for gentle daily cleaning scenarios such as tableware and the inner wall of a microwave oven, we provide a kitchen wipe compound composition that needs to reduce irritation, enhance moisturizing properties and material compatibility. Compared with Example 2, the formula ingredients are adjusted as follows, where the formula ratio of Example 2 is set to the original formula: The APG:AES ratio is adjusted to 5:2 (originally 4:3), APG is increased to 5% to achieve mild decontamination, and AES is reduced to 2% to reduce anionic surfactant irritation. The surface tension returns to 32mN / m, which can achieve a 90% removal rate for daily oil stains. However, the positive rate of the skin irritation patch test is reduced from 0.5% to 0.1%, making it suitable for daily skin contact with tableware.

[0060] The glycerin in the moisturizer is increased to 8% (originally 6%), and the propylene glycol is reduced to 3%, which improves the wetness and softness of the wipes. At this time, the base liquid viscosity is increased from 250ml Rise to 300m , avoid scratches when wiping glass / ceramic surfaces, and extend the moisturizing time after opening to 10 days (originally 7 days).

[0061] Replacing 0.2% benzalkonium chloride with 0.3% polyhexamethylene biguanide (PHMB), which has no mucosal irritation, is safer for tableware contact scenarios, complies with FDA food contact material standards, and retains 0.3% tea tree essential oil to enhance the natural antibacterial effect.

[0062] In this formula, in response to the gentle and safe needs of tableware cleaning, material corrosion tests were conducted. For example, when stainless steel tableware was soaked for 24 hours, it was found that there was no change in metallic luster when AES ≤ 2%, and the antibacterial persistence of PHMB was still able to reach a 24-hour antibacterial rate of 98%, meeting daily use needs.

[0063] Example 4 In this example, we provide a kitchen wipes formula formulated for heavy oil stains. By adjusting the proportions of certain ingredients, we aim to achieve superior cleaning performance for heavily oiled surfaces, such as kitchen stoves and ovens. This formula enhances oil absorption and cleaning, while sacrificing some mildness. Compared to Example 2, the adjusted proportions are as follows, with the proportions in Example 2 being the original formulation.

[0064] The surfactant ratio of APG:AES has been adjusted to 3:4 (from 4:3), and the anionic surfactant AES has been increased to 4% (from 3%). Leveraging its enhanced oil emulsification ability, the surface tension can be reduced to 25mN / m, shortening the dissolution time of solidified grease, such as burnt grease, and increasing the removal rate from 92% to 96%. In experiments using this formula to clean stovetop grease, a mixture of olive oil, lard, and food coloring was used to simulate heavy grease. Increasing the AES content to 4% reduced the removal time for 24-hour dried-on grease stains from 15 seconds to 8 seconds. Furthermore, in nonwoven fabric strength testing, the elongation at break remained above 15%, showing no significant decrease.

[0065] Newly added 0.5% fatty alcohol polyoxyethylene ether (AEO-9): The non-ionic surfactant compound enhances the penetration of high-melting-point oils and fats, such as animal fats, forming a ternary system of "APG (mild penetration), AES (rapid emulsification), and AEO-9 (solubilization of high-viscosity oils)".

[0066] The content of diatomaceous earth is increased to 3% (originally 2%), and its porous structure is used to absorb more liquid oil. At the same time, the content of sodium polyacrylate is maintained at 1% to avoid excessive amounts causing the wipes to become stiff, ensuring the "instant wipe and instant absorb" effect on heavy oil stains.

[0067] The benzalkonium chloride in the antibacterial agent is increased to 0.3% to cope with more complex bacterial contamination in heavy oil pollution scenarios, such as Escherichia coli, Staphylococcus aureus and other bacterial contamination, and can achieve a sterilization rate from 99.9% to 99.99% within 5 minutes. At the same time, the addition of benzalkonium chloride still meets the requirement of GB15979 ≤ 0.35%.

[0068] Example 5 In this embodiment, we provide a kitchen wipes compound composition suitable for maternal and child or pet family scenes, and adjust the addition ratio of some ingredients to adapt to sensitive groups, so as to achieve non-irritation, natural ingredients, and low allergenicity. Compared with Example 2, the adjustment ratio of the formula ingredients is as follows, wherein the formula ratio of Example 2 is set to the original formula. At the same time, according to the "GB / T38739-2020 Baby Wet Wipes" standard, ingredients such as AES and benzalkonium chloride are prohibited, and safe antibacterial and gentle cleaning are achieved through the compounding of natural ingredients. At the same time, the oil absorption capacity meets the cleaning needs of mild oil stains such as milk stains and rice paste.

[0069] The surfactant is completely replaced with 100% APG (6%), AES is removed to avoid possible dioxane residues of anionic surfactants, and 0.5% cocamidopropyl betaine (amphoteric surfactant) is added to enhance mildness. The surface tension is 35mN / m, and the human patch test confirms that the sensitization rate is <0.01%.

[0070] The diatomaceous earth content is reduced to 1.5%, and a new 1% corn starch modification (natural oil-absorbing ingredient) is added to remove light oil stains, such as oil stains on baby food, through physical adsorption, avoiding possible friction irritation of synthetic resins (polyacrylic acid).

[0071] The antibacterial agent is replaced with 0.5% nisin, which is a natural preservative. In addition, 0.5% rosemary extract is added, and there is no chemical antibacterial agent residue. SGS testing shows that the antibacterial rate against Escherichia coli is 95%, which meets daily antibacterial needs. In the odor test, 85% of people prefer natural plant fragrance.

[0072] The citric acid content is reduced to 0.5%, and the pH is controlled at 6.0-6.5, which is close to the pH of baby skin and avoids acidic irritation.

[0073] Example 6 In this example, we provide a kitchen wipes compound suitable for outdoor use in portable or dry environments, such as camping and deserts. The proportions of some ingredients are adjusted to achieve long-lasting moisturization, anti-evaporation, and lightweight properties. Compared to Example 2, the adjusted proportions of the ingredients are as follows, with the proportions of Example 2 being the original formula.

[0074] The deionized water content in the base liquid is reduced to 60%, and 5% polyethylene glycol (PEG-400) is added as an anti-evaporation agent to reduce water volatilization by forming a moisturizing film. For example, in an environment of 40°C and RH20%, the wet time is extended from 7 days to 15 days. At the same time, the total amount of base liquid is reduced to make the wet wipes lighter and thinner, and the weight of a single sheet is reduced from 40g to 35g.

[0075] In the environmental simulation experiment, the high temperature was set at 60°C and the wind speed was 5m / s. It was found that the combination of PEG-400 and chitosan reduced the water evaporation rate by 40%, and the flexibility of the wet wipes remained good in a dry environment, with a breaking strength of >20N.

[0076] The glycerin content in the moisturizer is reduced to 4%, and the propylene glycol content is increased to 6% to improve low-temperature stability. 0.3% chitosan is added as a film-forming agent to form a water-locking film on the surface of the wipes to prevent rapid drying when used outdoors.

[0077] The sodium polyacrylate in the oil absorbent is increased to 1.5%, which can enhance the grease locking ability, and the diatomaceous earth is maintained at 2%, ensuring that barbecue oil stains can be absorbed with a single wipe in a water-scarce environment without the need for repeated dipping in water.

[0078] Example 7 In this example, we provide a kitchen wipe compound suitable for use with specialized materials, such as non-stick pans and coated cookware. Adjustments to the ratios of certain ingredients are made to achieve scratch- and corrosion-resistant, gentle cleansing. Compared to Example 2, the adjusted ratios are as follows, with the ratios in Example 2 being the original formulation.

[0079] In this formula, the APG content in the surfactant is increased to 7%. There is no AES in this formula. Its non-ionic properties are used to reduce chemical corrosion of the coating. At the same time, 0.2% of polyoxyethylene sorbitan monooleate (Tween-80) is added to enhance the dispersibility of oil stains on the surface of the non-stick pan without forming residue.

[0080] At the same time, the diatomaceous earth content in the oil absorbent is reduced to 1%, and the remaining content is replaced by 1% modified silica with a particle size of ≤2μm. The fine particles avoid scratching the coating while maintaining the oil absorption capacity, and the adsorption capacity of edible oil is up to 4 times its own weight.

[0081] During the pH adjustment process, citric acid is removed and replaced with 0.5% sodium citrate. The pH is maintained in the neutral range of 6.5-7.0 to prevent acidic corrosion of the coating. For example, Teflon coating is easily damaged when the pH is less than 5, and the pH in this formula can well protect the Teflon coating.

[0082] The composition of the ingredients in this formula has passed the coating wear resistance test. For example, after 500 wipes, it was found that the combination of modified silica and neutral formula caused the coating thickness loss to be less than 5%, while the traditional formula loss was 15%. At the same time, the oil stain removal rate was still able to reach 85%, and the cleaning effect can meet daily needs.

[0083] Example 8 An application of a kitchen wet wipe compound composition comprises the above-mentioned kitchen wet wipe compound composition, and the kitchen wet wipe compound composition is used for preparing kitchen wet wipes.

[0084] Example 9 A method for preparing a kitchen wipes composite composition, used to prepare the kitchen wipes composite composition described in the above embodiment, specifically comprising the following steps: Step 1: Diatomaceous earth pretreatment: Nano-grinding to a particle size of ≤5μm and surface hydroxyl modification to improve hydrophilicity and avoid agglomeration that affects oil absorption efficiency.

[0085] Step 2: Mixing order: first dissolve alkyl polyglycoside APG, fatty alcohol polyoxyethylene ether sulfate sodium AES, and α-olefin sulfonate sodium in 45-50℃ warm water, then add moisturizer and oil absorbent in sequence, and finally cool to below 30℃ and add antibacterial agent and essential oil.

[0086] Step 3: Non-woven fabric impregnation: Use the "two dips and two rolls" method, and control the liquid absorption rate at 180-200% to ensure that the base liquid is evenly distributed and there is no penetration residue on the edge.

[0087] Through the cycle of two dipping (immersion) and two rolling (rolling), the impregnation liquid of the kitchen wet wipes composite composition fully penetrates into the interior of the non-woven fabric fibers.

[0088] First Dip: For the first dip, the nonwoven substrate is pulled over guide rollers and completely immersed in the first dipping tank. The tank contains the prepared treatment solution. The treatment solution penetrates the nonwoven through capillary action and fiber adsorption, filling the interfiber spaces and initially wetting the substrate.

[0089] First Pressing: After the nonwoven fabric emerges from the impregnation tank, it enters the first pair of rollers, typically rubber or metal rollers. The pressure is adjusted according to the type of kitchen wipe. Excess treatment liquid is squeezed out of the nonwoven fabric to control the liquid carryover rate. The roller pressure ensures that the treatment liquid is evenly distributed among the fibers, preventing localized accumulation of liquid.

[0090] Re-impregnation: The second impregnation, after the first rolling, the non-woven fabric enters the second impregnation tank or the same tank again. During the second impregnation, the non-woven fabric fibers are partially wetted, and the treatment liquid is easier to penetrate into the internal fiber layer, which is especially suitable for thick or high-density non-woven fabrics.

[0091] Re-rolling: The second rolling, the re-impregnated nonwoven fabric passes through the second pair of rollers, the pressure can be the same as the first rolling or different.

[0092] The "two-dip, two-pad" method employed in this invention significantly improves the penetration depth and uniformity of the treatment solution compared to a "one-dip, one-pad" method, reducing surface residue. This method is suitable for nonwovens with dense fiber structures, ensuring that the internal fibers are fully exposed to the kitchen wipes' liquid, enhancing their performance.

[0093] The above steps demonstrate a consistent dissolution sequence and stability: first, dissolve the surfactant at 50°C, then cool down to add the oil absorbent and antibacterial agent. The diatomaceous earth is nano-grinded to ≤5μm to prevent agglomeration. Tea tree oil is added below 30°C to prevent volatilization. Centrifugal stability testing is performed at a speed of 3000 rpm for 30 minutes to ensure no stratification and to confirm that the base liquid contains no precipitation at the appropriate ratios of the components.

[0094] According to tests, the optimal liquid absorption capacity of 20g / m² bamboo fiber cloth is 36-40g / m², which can ensure uniform wetting and no debris is removed when wiped.

[0095] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
