Description

Technical Field

[0001] The invention relates to the technical field of daily chemicals, in particular to a multifunctional cleansing milk and a preparation method thereof. Background Art

[0002] Kitchen hard surface cleaning products are mainly highly alkaline and can cause certain damage to the skin. They cannot remove stains that are highly adhesive in daily life. For example, rust stains on stainless steel cookware in the kitchen cannot be removed by general cleaning products. The common method is to use a cleaning ball (commonly known as a steel wool), which mainly removes them through mechanical friction. However, this method can easily leave many scratches on the surface of stainless steel cookware, which not only affects the appearance but also damages the utensils.

[0003] Therefore, there is an urgent need to provide a multifunctional cleaning lotion with moderate friction hardness, mild performance and stability to clean the dirt, grease, old dirt and the like that are difficult to remove in daily life. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a multifunctional cleaning milk and a preparation method thereof. The main feature is that the cleaning milk contains an anion system of abrasive particles and is in an emulsion state. The present invention mainly relates to a multifunctional cleaning milk for surface stains of most hard surfaces and some soft surfaces (artificial leather, rubber, etc.) of products. The product is relatively mild and has a strong decontamination ability. Its appearance is a uniform white emulsion, and the material body mainly contains a large amount (about 30%) of abrasive particles, and these abrasive particles exist uniformly and stably in the material body. The cleaning strength of the abrasive particles is moderate in hardness and softness. The abrasive particles and other ingredients in the formula, such as various surfactants and solvents, work synergistically to remove stains under various forces such as penetration, emulsification, softening, and friction.

[0005] The present invention is achieved through the following technical solutions:

[0006] The first object of the present invention is to provide a multifunctional cleansing milk, wherein the raw materials of the multifunctional cleansing milk include the following components by weight:

[0007]

[0008]

[0009] The abrasive particles are selected from calcium carbonate; the particle size of the abrasive particles is 400-800 meshes.

[0010] In one embodiment of the present invention, the surfactant is selected from one or more of anionic surfactants, amphoteric surfactants and nonionic surfactants.

[0011] In one embodiment of the present invention, the anionic surfactant is one or more of sodium alkylbenzene sulfonate, sodium fatty alcohol polyether sulfate and sodium secondary alkyl sulfonate;

[0012] And / or, the amphoteric surfactant is one or more of cocamidopropyl betaine, sodium lauroamphoacetate, lauroyl hydroxysulfobetaine, cocamidopropyl dimethyl ammonium oxide and amino acid surfactant; the amino acid surfactant is disodium cocoyl glutamate, etc.

[0013] And / or, the nonionic surfactant is one or more of C8-10 alkyl glycoside, C10-Gubert alcohol ethoxylate, isomeric 13-carbon fatty alcohol ethers, secondary alkyl alcohol polyoxyethylene ether and fatty alcohol polyoxyethylene ether.

[0014] In one embodiment of the present invention, the chelating agent includes trisodium methylglycine diacetate and / or tetrasodium glutamate diacetate.

[0015] In one embodiment of the present invention, the solvent includes one or more of water, diethylene glycol butyl ether, propylene glycol and isohexylene glycol.

[0016] In one embodiment of the present invention, the suspending agent is selected from acrylic acid (ester) copolymers.

[0017] In one embodiment of the present invention, the preservative is a mixture of methylisothiazolinone and benzisothiazolinone.

[0018] In one embodiment of the present invention, the corrosion inhibitor is selected from sodium silicate and / or urea.

[0019] In one embodiment of the present invention, the pH adjuster is selected from potassium hydroxide and / or sodium hydroxide.

[0020] The second object of the present invention is to provide a method for preparing the multifunctional cleansing milk, comprising the following steps:

[0021] (1) mixing and stirring a solvent and abrasive particles to obtain an abrasive pretreatment liquid;

[0022] (2) Add the surfactant and the detergent synergist into water and stir to dissolve; add the suspending agent and stir to dissolve evenly; then add the abrasive pretreatment liquid obtained in step (1) and stir to discharge bubbles and distribute evenly; then add the corrosion inhibitor and stir to dissolve evenly; adjust the pH to 9.0-10.0; add the flavor and preservative and stir to dissolve evenly.

[0023] The biggest difference between the product formula proposed by the present invention and the formula of similar products is that in order to improve the ability to remove old stains and increase physical friction, suitable friction particles are introduced. At the same time, the viscosity of the system is controlled to give it a certain rheological property for easy use. The cleaner is in an emulsion state, and this emulsion state is caused by the presence of a large number of abrasive particles in the formula. In order to ensure the stable existence of the abrasive particles in the product and the uniformity of the product, the formula must consider adding a suitable suspending agent. The suspending agent can first suspend the particles so that they will not sink to the bottom, and the particles will be evenly distributed in the material body during the shelf life of the product. Secondly, the suspending agent cannot significantly increase the viscosity of the product, so as to affect the appearance of the product and the convenience of use. The cleaner contains a certain amount of friction agent components, which can be used with cleaning tools to remove dirt, grease, old and stale dirt that are difficult to remove in daily life. The friction agent used in the present invention has moderate friction hardness, mild and stable performance. It also has a relatively good cleaning power for leather soft-package items.

[0024] The above technical solution of the present invention has the following advantages compared with the prior art:

[0025] (1) The present invention provides a multifunctional cleaning milk and a preparation method thereof. The product of the present invention adds friction particles, which have moderate hardness and stable performance. The friction particles cooperate with the original emulsification and penetration ability of the product to further enhance the removal effect of stubborn stains. In addition, some polyacrylic acid polymer anti-redeposition agents can be added to the formula. These polymers are adsorbed on the surface of crystalline objects to prevent crystal growth and facilitate the next cleaning.

[0026] Compared with similar products, the multifunctional cleaning milk of the present invention does not belong to strong alkali or strong acid products. Its basic functions are deep cleaning and decontamination. It has a wide range of applications, including removing stains on kitchen stoves, stainless steel cookware, baking trays, leather utensils, bathroom faucets, white shoe edges, data cables and other items.

[0027] (2) The multifunctional cleaning lotion of the present invention has multiple effects such as penetration, emulsification, complexation, friction, etc., and has both physical and chemical decontamination properties. It has a good cleaning effect on hard-to-clean utensils such as burnt or oxidized residues on kitchen stoves and cookers. DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0029] The present invention provides a multifunctional cleansing milk, which comprises the following components in parts by weight:

[0030]

[0031] In the above formula, the surfactant refers to a combination of one or more surfactants with good permeability and strong detergency, such as sodium alkylbenzene sulfonate, C8-10 alkyl glycoside, C10-Gubert alcohol ethoxylate, isomeric 13-carbon fatty alcohol ethers, and secondary alkyl alcohol polyoxyethylene ether. The chelating agent uses the relatively mild and green amino acid chelating agent methylglycine diacetate trisodium, and the same is suitable for glutamic acid diacetate tetrasodium. Solvent substances are mainly diethylene glycol butyl ether, propylene glycol, isohexanediol, etc. Considering the odor, performance and other cost reasons, diethylene glycol butyl ether is mainly used in the formula. Suspending agents mainly refer to acrylic acid (ester) copolymers with suspension properties, which can suspend insoluble substances in the formula. Abrasive particles are mainly inorganic salt friction agents, mainly calcium carbonate and silicon dioxide, hydrated silica, etc., and calcium carbonate (400-800 mesh) is preferred. Detergent enhancer is a multifunctional composite raw material that can significantly improve detergent performance. The preservative is preferably a compound of methylisothiazolinone and benzisothiazolinone, which is resistant to high temperatures and has a wider pH range, making it more suitable. Sodium silicate and urea are both corrosion inhibitors, and they work together to prevent hardware such as kitchens and bathrooms from being corroded during the cleaning process: potassium hydroxide solution (pH regulator) is generally used in conjunction with a suspending agent, and the pH is adjusted to the specified range at the same time. The neutralized potassium salt also has a good anti-corrosion synergistic effect on the electrode.

[0032] The surfactant, solvent, chelating agent and friction particles in the formula work together to improve the comprehensive decontamination performance of the product. Optimization of surfactant combination performance: anionic surfactant, nonionic surfactant and a small amount of amphoteric surfactant are used to work together. The anionic system has a good decontamination effect, but it has a certain corrosive effect on some stainless steel. Therefore, urea and sodium silicate are added to the formula as corrosion inhibitors to make the whole formula have a good synergistic effect.

[0033] Furthermore, the particle size of the abrasive particles in the formulation system is preferably 400-800 mesh particles, which have good decontamination performance, almost no scratches on hard surfaces, and also have a good cleaning effect on some soft surfaces.

[0034] Furthermore, the multifunctional cleaning milk comprises the following components by weight:

[0035]

[0036]

[0037] Unless otherwise specified, the experimental methods used in the following examples are all conventional methods, and the materials, reagents, etc. used are all available from commercial sources unless otherwise specified.

[0038] Among them, acrylic acid (ester) copolymer was purchased from Lubrizol, ACRYTHIX L-20 Polymer; the stain removal synergist was purchased from Hangzhou Fides, STENOLAM 115G).

[0039] Example 1

[0040] This embodiment provides a multifunctional cleansing milk and a preparation method, which comprises the following components by weight:

[0041]

[0042] This embodiment provides a method for preparing a multifunctional cleansing milk, and the process operation is as follows:

[0043] Weigh out the components according to the formula. First, divide the deionized water into two parts. Add propylene glycol (polyol) and solvent diethylene glycol butyl ether to one part of the water and stir to mix evenly. Add abrasive particles (400 mesh calcium carbonate) to fully wet, stir evenly and set aside to obtain the abrasive pretreatment liquid. Another part of deionized water is added to the mixing pot, and the linear alkylbenzene sulfonate sodium, C8-10 alkyl glucoside, cocamidopropyl betaine, secondary alcohol polyoxyethylene ether, and detergent synergist in the formula are added to the water in turn and stirred to dissolve evenly (if the surfactant is not completely dissolved, it can be heated to 45°C-55°C appropriately), and the chelating agent methylglycine diacetate trisodium is added to stir and dissolve evenly, and then the suspending agent acrylic acid (ester) copolymer aqueous solution is added (diluted with twice the water and stirred evenly), and after stirring and dissolving evenly, the stirring is stopped, and then the abrasive pretreatment liquid is added and stirred evenly to discharge bubbles and evenly distribute, and then urea and sodium silicate aqueous solutions are added respectively and stirred evenly, and finally potassium hydroxide solution is used to adjust the pH to 9.0-10.0, and then flavors, preservatives, etc. are added and stirred evenly. Finally, the appearance of the product is detected to be a uniform and delicate emulsion, and the physical and chemical indicators are pH value of 9.0-10.0 and viscosity of 2000mpa.s-5000mpa.s (25°C). During the stirring process, the stirring paddle should be below the liquid surface to avoid introducing bubbles that may affect the state of the material.

[0046] Comparative Example 1

[0047] This comparative example provides a multifunctional cleansing milk and a preparation method, which is similar to Example 1, except that 100-mesh ground calcium carbonate particles are added.

[0048] Comparative Example 2

[0049] This comparative example provides a multifunctional cleaning milk and a preparation method, which is similar to Example 1, except that 200-mesh ground calcium carbonate particles are added.

[0050] Comparative Example 3

[0051] This comparative example provides a multifunctional cleaning milk and a preparation method, which is similar to Example 1, except that 1000-mesh ground calcium carbonate particles are added.

[0052] Comparative Example 4

[0053] This comparative example provides a multifunctional cleaning milk and a preparation method, which is similar to Example 1, except that 1500-mesh abrasive particles of calcium carbonate are added.

[0054] Performance Testing

[0055] (1) Decontamination effect test

[0056] The decontamination test was conducted on stains on items in different areas. The test method is: pour an appropriate amount of cleaning milk on the stain or on the scouring pad, use the same force and frequency to wipe the surface of the stain, and control the size of the stain to be basically the same, until the stain on the surface of the object has no obvious change (the standard for judging the degree of cleanliness), and finally wipe the surface with a clean wet towel and record the wiping time. Sensory scores are given based on satisfaction with the wiping effect. The test feedback is shown in Table 1 below. The maximum score for the test is 10 points, and the scores are given based on comprehensive evaluation of the overall decontamination effect, difficulty, etc.

[0057] Wipe down items and areas:

[0058] ① Stainless steel stoves, stainless steel baking trays, trays, etc.: mainly burnt and blackened food residues that are difficult to clean. The main stains are grease, dust, food seasoning residues, etc.

[0059] ②Stove: mainly grease, food residues, dust, etc.

[0060] ③Bathroom faucets and basins: mainly scale, sebum stains, etc.

[0061] ④Shower glass door: mainly scale, sebum stains, dust, etc.

[0062] ⑤White shoe edge: generally made of rubber, mainly with some fine dust particles, water stains and stains mixed and adhered to it.

[0063] ⑥ Artificial leather chair surface: mainly composed of sebum dirt, fine dust particles, oil stains, etc. mixed together.

[0064] Table 1

[0065]

[0066]

[0067] Compare the cleaning time to judge the effect of different particle sizes on the detergency. For hard surfaces, the larger the particle size, the slightly longer the cleaning time, indicating that the cleaning power is slightly worse. When the particle size is reduced to a certain extent, the cleaning power does not change much, or has a decreasing trend. Analyzing the reasons, when the friction particles are large, the specific surface area of ​​the particles per unit volume is low, the contact area between the particles and the clean surface is small, and the friction is affected to a certain extent. When the friction particle size is very small, the particles have better ductility under the action of external force, and it is easy to spread evenly. The average friction force acting on the surface of the object becomes smaller, which makes the action time longer.

[0068] (2) Regarding the cleaning effect, three samples with different particle sizes were selected for sensory evaluation and scoring of the wiping effect. The results are shown in Table 2:

[0069] Table 2

[0070]

[0071] From the above test data, in terms of cleanliness, the cleaning power of the emulsion of comparative example 3 (particle size 1000 mesh) is slightly worse than that of example 1 (particle size 400 mesh). It can be seen that when the particle size continues to increase to 1000 mesh, the cleaning effect is reduced to a certain extent. In terms of surface finish, the larger the particle size, the greater the wear on the surface of the object. When the particle size is reduced to a certain extent, the wear on the surface of the object tends to be the same. That is, when the particles are larger, there is a certain wear on the surface of the object, and when the particles are smaller, the surface finish of the object is higher. This is consistent with the trend of changes in particle size and friction.

[0072] Judging from the above detergency and overall cleaning effect, in order to take into account the overall requirements of hard surface and some soft surface products, 400-800 mesh particle size is the best choice.

[0073] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
