Description

Technical Field

[0001] This invention relates to the field of cleaning agent technology, specifically to a highly efficient cleaning agent for heavy kitchen grease and its preparation method. Background Technology

[0002] Kitchen heavy-duty grease cleaners are core products in the home cleaning industry, widely applicable to various scenarios such as range hoods, stovetops, wall tiles, and bathroom glass. They are mainly used to remove grease, stubborn dirt, and years of accumulated heavy grease from daily use, making them essential for maintaining a clean home environment. Currently, most cleaning agents on the market achieve their cleaning function through the compounding of surfactants and alkaline additives. While some products can meet basic cleaning needs, there is still room for improvement in terms of ingredient synergy and functional compatibility.

[0003] However, some existing kitchen heavy grease cleaners use a single cleaning ingredient or an unreasonable compounding formula, resulting in limited cleaning, emulsifying, dispersing, and penetrating abilities, making it difficult to effectively deal with stubborn heavy grease stains. Some products neglect environmental performance, with ingredients that are not easily degraded in the natural environment, easily causing environmental pollution. At the same time, some products lack targeted anti-corrosion design, causing damage to the surface of common utensils such as stainless steel after use, affecting the service life of the utensils. These problems seriously restrict the overall user experience and practicality of the products. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a highly efficient kitchen cleaning agent for heavy oil stains and its preparation method, which solves the problems of limited cleaning ability, environmental pollution, or corrosion of utensils caused by the single cleaning component or insufficient environmental friendliness in existing technologies.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a highly efficient kitchen oil stain cleaner, comprising the following percentage raw materials: surfactant A 3%-5%, surfactant B 3%-5%, sodium metasilicate pentahydrate 3%-5%, strong alkali 0.475%-0.525%, disodium 0.19%-0.21%, and the balance being deionized water.

[0006] By adopting the above technical solution, the precise ratio of surfactant A, surfactant B, sodium metasilicate pentahydrate, strong alkali and disodium salt is used to create a synergistic effect through complementary functions of each component. This results in a system that combines strong detergency, emulsification and dispersion properties with environmental friendliness. Furthermore, the addition of deionized water creates an aqueous system, thus achieving a cleaning effect that is outstanding, easily degradable, and friendly to metal utensils.

[0007] Preferably, surfactant A is fatty alcohol polyoxyethylene ether AEO-7 with an HLB value of 12.0-13.0, and surfactant B is fatty alcohol polyoxyethylene ether AEO-9 with an HLB value of 13.5-14.5.

[0008] By adopting the above technical solution, and using specific types of fatty alcohol polyoxyethylene ethers AEO-7 and AEO-9 as composite surfactants, the two have strong HLB value compatibility, which can accurately match the emulsification requirements of oil stains and synergistically enhance penetration and decomposition capabilities. Therefore, the effect of rapidly breaking down stubborn oil stains and significantly improving cleaning efficiency is achieved.

[0009] Preferably, the strong base is selected from sodium hydroxide or potassium hydroxide, and the disodium is disodium ethylenediaminetetraacetate.

[0010] By adopting the above technical solution, sodium hydroxide or potassium hydroxide is used as a strong alkali component, combined with disodium ethylenediaminetetraacetate. The strong alkali can enhance the saponification and decomposition of oil stains, while disodium can chelate metal ions and stabilize the system. The two functions work synergistically, thus achieving a balance between cleaning effect and system stability.

[0011] Preferably, the cleaning agent has an active ingredient content of 8%-9% and a pH value of 10.5-11.5.

[0012] By adopting the above technical solution, the active ingredient content and pH value of the cleaning agent are limited to a reasonable range, which not only ensures the effectiveness of active ingredients such as surfactants, but also avoids damage to the equipment caused by excessively high pH values. Therefore, a cleaning, efficient and safe-to-use effect is achieved.

[0013] Preferably, the sodium metasilicate pentahydrate is used after being treated by air jet milling, resulting in a particle size of 50-150 μm, and is dried at 80-100℃ for 1-2 hours to remove free moisture.

[0014] By adopting the above technical solution, the agglomeration phenomenon is reduced and the dissolution rate and dispersion uniformity of sodium metasilicate pentahydrate are improved by air jet milling and drying pretreatment. Therefore, the raw materials are more fully mixed and the product performance is more stable.

[0015] A method for preparing a highly effective kitchen degreaser, the method comprising: S1. Weigh out the deionized water according to the ratio, add it to the stirring equipment, and stir at room temperature to make the deionized water flow evenly. S2. Under continuous stirring, add surfactant A and surfactant B to the deionized water obtained in S1, and keep stirring until the two surfactants are completely dissolved to form a mixed solution. S3. Continue stirring and add sodium metasilicate pentahydrate to the mixed solution obtained in S2. Adjust the stirring parameters and continue stirring until the sodium metasilicate pentahydrate is fully dispersed and dissolved. S4. Add strong alkali and disodium in sequence to the stirring system of S3, and continue stirring while maintaining the current stirring state to ensure that all raw materials are fully mixed and dissolved. S5. After stirring, let the resulting solution stand and test the active ingredient content and pH value of the solution. If the test is qualified, the target cleaning agent is obtained.

[0016] By adopting the above technical solution, the preparation process of step-by-step feeding and gradual dissolution follows the logic of adding water first, then surfactants, then additives, and finally stabilization, ensuring that all raw materials are fully integrated under suitable conditions. Therefore, the process is simple and controllable, and the product quality is uniform.

[0017] Preferably, the stirring equipment is a closed electric stirrer or a stirring vessel, with a stirring speed of 300-500 r / min, a stirring time of 1-2 min, and the solution temperature controlled at 20-25℃ during the stirring process.

[0018] By adopting the above technical solution, the use of a closed stirring device and precise control of stirring speed, time and temperature avoids the mixing of external impurities and provides a stable environment for the dissolution of raw materials, reducing the risk of component volatilization or deterioration. Therefore, the product achieves high purity, better corrosion resistance and stability.

[0019] Preferably, in step S2, the stirring speed is the same as in step S1, the stirring time is 3-5 minutes, and surfactant A and surfactant B are added to the deionized water by slow dripping or batch addition, with an interval of 1-2 minutes between each batch addition.

[0020] By adopting the above technical solution, the surfactant is added slowly or in batches, and the addition interval and stirring parameters are controlled, thus avoiding the problem of insufficient dissolution caused by excessively high local concentration of surfactant. Therefore, the system is uniformly dispersed and the active ingredient functions fully.

[0021] Preferably, in step S3, the stirring speed is adjusted to 500-700 r / min, the stirring time is 4-6 min, and the sodium metasilicate pentahydrate is a dry, non-lumpy powder.

[0022] By adopting the above technical solution, the stirring speed and time are adjusted according to the dissolution characteristics of sodium metasilicate pentahydrate to meet its dispersion requirements, promoting its rapid dissolution without residual agglomeration. Therefore, the results of high raw material utilization and uniform product cleaning effect are achieved.

[0023] Preferably, in step S4, a strong alkali is added first, and disodium is added after the strong alkali has completely dissolved. The stirring speed is the same as in step S3, and the stirring time is 5-8 minutes. In step S5, the settling time is 2-3 minutes. If the test fails, the ratio of each raw material is adjusted according to the test results, and steps S1-S4 are repeated.

[0024] By adopting the above technical solution, the order of adding strong alkali and disodium is clearly defined, avoiding adverse reactions between components. At the same time, product quality is controlled by static testing, and the ratio is adjusted in time when the product is not qualified. Therefore, the system has strong stability and the product qualification rate is high.

[0025] This invention provides a highly effective cleaning agent for heavy-duty kitchen grease and its preparation method. It has the following beneficial effects: 1. This invention achieves a comprehensive cleaning effect of strong decontamination, emulsification, dispersion and penetration by using a technical solution of reasonable compounding of raw materials and synergistic use of surfactants with disinfection function. At the same time, it has the characteristics of being environmentally friendly, easy to degrade and corrosion resistant to common metals. Compared with the existing technical solutions with single cleaning ingredients or insufficient environmental protection, this invention solves the problems of limited decontamination ability, easy pollution of the environment or corrosion of utensils.

[0026] 2. The present invention adopts a simplified preparation process and convenient use method, which achieves the effects of low preparation cost, simple and efficient operation. No complicated pretreatment or disassembly steps are required during use, and rapid cleaning can be achieved in multiple scenarios. Compared with the existing technology, which has a complicated preparation process and requires disassembly of the equipment or repeated wiping during use, it solves the problems of high preparation difficulty, low use efficiency and inconvenient operation.

[0027] 3. This invention adopts an optimized formula system and a multi-scenario adaptability technical solution, achieving the effects of mild odor, safe use and wide applicability. The water-based formula is not easily volatile, which is more friendly to human health and can cover a variety of cleaning scenarios in kitchens and bathrooms. Compared with existing technologies that have pungent odors, safety hazards or limited applicable scenarios, this invention solves the problems of poor user experience, insufficient safety and limited adaptability.

[0052] Table 1. Performance test data of Examples 1-3 and Comparative Examples 1-6

[0053] Based on the differences in Examples 1-3, Comparative Examples 1-6, and the performance test data table, it can be seen that the core advantage of this invention stems from the synergistic effect of six key processes: batch or dropwise addition of surfactants, pretreatment of sodium metasilicate pentahydrate by airflow pulverization and drying, orderly addition of strong alkali and disodium ethylenediaminetetraacetate, precise segmented adjustment of stirring speed, closed stirring protection, and qualified discharge after standing. Furthermore, the precise adaptation of parameters in each step significantly and positively impacts the cleaning agent's detergency, dispersion uniformity, stability, corrosion resistance, and active ingredient retention rate. It also achieves a triple synergistic optimization of surfactant solubility, raw material mixing uniformity, system stability, and environmental safety.

[0054] Comparative Examples 1-6 all experienced a targeted decline in performance due to the absence or replacement of a single core process: Comparative Example 1 added the surfactant all at once, resulting in insufficient dissolution, uneven dispersion, a decrease in active ingredient content to 7.6%, a prolonged detergency time to 2.5 minutes, and slight stratification; Comparative Example 2 omitted the pretreatment of sodium metasilicate pentahydrate air jet milling and drying, making it difficult to disperse and dissolve the original blocky form, resulting in an active ingredient content of only 7.2%, poor dispersion uniformity, and obvious stratification and precipitation, with a detergency time of 3.0 minutes; Comparative Example 3 reversed the order of adding the strong alkali and disodium ethylenediaminetetraacetate, disrupting the system's solubility coordination, resulting in generally poor dispersion uniformity and poor detergency... The cleaning time was extended to 2.2 min; Comparative Example 4 used an open stirring device, which easily introduced foreign impurities and caused slight volatilization of raw materials, with an active matter content of 7.5% and a cleaning time of 2.8 min, and caused slight pitting corrosion on stainless steel; Comparative Example 5 did not adjust the stirring speed during the dissolution stage of sodium metasilicate pentahydrate, resulting in insufficient dispersion and dissolution of raw materials, with an active matter content of only 7.0%, poor dispersion uniformity, and obvious stratification and precipitation, and a cleaning time as long as 3.2 min; Comparative Example 6 omitted the settling step after stirring and directly tested the discharge, resulting in the system not being completely stable and causing slight stratification, with a cleaning time of 2.4 min, fully demonstrating the indispensability of each process step.

[0055] Examples 1-3 all exhibit excellent performance: active ingredient content of 8.0%-9.0%, pH value of 10.5-11.5, detergency time of 1.0-1.5 min, good to excellent dispersion uniformity, no stratification or precipitation after 72 hours of standing, no corrosion to stainless steel, and outstanding ease of use. Among them, Example 2 achieves the optimal balance of performance, with an active ingredient content of 8.3%, pH value of 10.9, and a detergency time of only 1.0 min, fully meeting the inspection standards and achieving optimal fit between detergency efficiency, system stability, and safety of use. Example 1 maintains process stability with minimal parameters, adapting to the needs of small-scale preparation and cost control. Example 3 meets the requirements of large-scale production with maximum parameters, balancing capacity and product consistency. Both examples jointly verify the rationality and application flexibility of the parameter range of this invention.

[0056] The compatibility of parameters in each step is crucial for performance assurance: S1 The stirring speed, temperature, and time are matched to the flow state requirements of deionized water, laying the foundation for subsequent raw material dissolution; S2 The method of adding surfactants, the interval time, and the stirring parameters are adapted to their dissolution characteristics to ensure full release of active ingredients; S3 The pretreatment process of sodium metasilicate pentahydrate and the adjustment of stirring speed ensure rapid dispersion and dissolution; S4 The order of adding raw materials and the stirring parameters are adapted to the system's dissolution requirements to avoid reaction conflicts; S5 The settling time and testing standards ensure that the finished product quality meets the standards; Precise control of raw material ratios throughout the entire process ensures that the active ingredient content and pH value remain stable within the optimal range.

[0057] Example 2 achieves the optimal balance between decontamination efficiency, stability and safety through precise adaptation of parameters throughout the entire process; the process collaboration system of Examples 1-3 not only avoids performance loss or cost waste caused by parameter boundaries, but also covers the needs of multiple scenarios such as laboratory research and development, small and medium-sized production and large-scale mass production.

[0058] In summary, this invention effectively solves the pain points of traditional kitchen heavy oil stain cleaners, such as long cleaning time, uneven dispersion, poor stability, easy corrosion of utensils, and inconvenience of use. It significantly improves the overall performance of the cleaner. Example 2 has the best cost performance and potential for large-scale production and can be directly applied to the industrial mass production of household cleaning products. The parameter flexibility of Examples 1-3 can be adapted to the needs of multiple scenarios such as laboratory research and development, special cleaning scenarios, and small-scale customization. It provides a standardized and replicable technical solution for the research and development and industrial production of efficient and environmentally friendly kitchen cleaners, and at the same time provides a new path for raw material synergy and process optimization in the field of cleaning products.
