Description

Technical Field

[0001] The present invention relates to the technical field of detergents, in particular to the IPC C11D1 field, and further relates to an oil stain removing kitchen treasure and a preparation method thereof. Background Art

[0002] In daily life, removing oil stains in the kitchen has always been the focus and difficulty of every family. Due to the very complex composition of the oil scale in the kitchen, the decontamination effects of ordinary washing powders and decontamination powders need to be improved.

[0003] CN201110391263 discloses a composition of a cooker oil stain remover, which is made of the following raw materials in weight ratio: sodium hydroxide 2-6; sodium carbonate 10-20; sodium dichloroisocyanurate 1-3; sodium tripolyphosphate 3-6; polyether 1-2; water 60-70. When making it, heat and mix the above raw materials according to the formula dosage, and stir evenly. The present invention is simple to make and convenient to use, and is suitable for washing oil stains on the kitchen and cookers. However, the composition prepared by this technical solution contains more sodium hydroxide and sodium carbonate, and has a strong corrosive effect.

[0004] CN201611211753 discloses a preparation method of an environment-friendly kitchen oil stain cleaning agent. The invention cultivates rich microorganisms inside the kitchen oil stains, selects beneficial strains, puts them into a liquid medium for cultivation, uses kitchen waste oil as an inducer to screen them, obtains strains with high decomposition ability for kitchen waste oil, then through high-speed separation, obtains effective enzyme substances, and then mixes them with natural product extracts. Using geniposide as a cross-linking agent, combines the enzyme substances with the extracted beneficial substances, and modifies them with maleic anhydride, thereby obtaining an environment-friendly kitchen oil stain cleaning agent. It effectively solves the problems of traditional kitchen oil stain cleaning agents, such as strong corrosiveness, which can cause irritation and harm to the skin of users, unpleasant smell, and dizziness and vomiting in people during long-term use. However, obviously, this technical solution is relatively complex. Summary of the Invention

[0005] To solve the above technical problems, in the first aspect of the present invention, an oil stain removing kitchen treasure is provided. By mass percentage, the raw materials include: surfactant 3-13%, solvent 3-12%, oil remover 1-4%, and the balance is water.

[0006] Preferably, for an oil stain removing kitchen treasure, by mass percentage, the raw materials include: surfactant 5-10%, solvent 5-8%, oil remover 1-2%, and the balance is water.

[0007] In some preferred embodiments, the surfactant is selected from one or a combination of two of anionic surfactants and non-ionic surfactants.

[0008] The applicant's research found that the surfactant includes a combination of an anionic surfactant and a non-ionic surfactant. When the weight ratio of the anionic surfactant to the non-ionic surfactant is 1:(2 - 5), the detergency and stability can be improved, and at the same time, the addition amount of the surfactant can be reduced. The anionic surfactant and the non-ionic surfactant can form mixed micelles in the solution. The anionic surfactant is beneficial for maximum solubilization, and the non-ionic surfactant is easy to broaden the allowable value of water hardness, reduce the critical micelle concentration of the solution, produce a synergistic effect, improve surface activity, and reduce the surfactant dosage.

[0009] Preferably, the surfactant includes a combination of an anionic surfactant and a non-ionic surfactant.

[0010] Preferably, the weight ratio of the anionic surfactant to the non-ionic surfactant is 1:(2 - 5).

[0011] Preferably, the weight ratio of the anionic surfactant to the non-ionic surfactant is 1:3.5.

[0012] Preferably, the anionic surfactant is selected from one or more combinations of isomeric alcohol ethoxylate carboxylate, alcohol ether carboxylate, oil and fat ethoxylate sulfonate, fatty acid methyl ester sulfonate, and fatty alcohol polyoxyethylene ether sulfate.

[0013] Preferably, the anionic surfactant includes isomeric alcohol ethoxylate carboxylate.

[0014] Preferably, the isomeric alcohol ethoxylate carboxylate is purchased from Wuhan Kamike Technology Co., Ltd.

[0015] Preferably, the non-ionic surfactant is selected from one or more combinations of isomeric alcohol polyoxyethylene ether, fatty acid methyl ester ethoxylate, and fatty alcohol polyoxyethylene ether.

[0016] Preferably, the non-ionic surfactant is selected from the combination of isomeric alcohol polyoxyethylene ether and fatty acid methyl ester ethoxylate, and the weight ratio of isomeric alcohol polyoxyethylene ether to fatty acid methyl ester ethoxylate is 1:(0.2 - 1).

[0017] Preferably, the non-ionic surfactant is selected from the combination of isomeric alcohol polyoxyethylene ether and fatty acid methyl ester ethoxylate, and the weight ratio of isomeric alcohol polyoxyethylene ether to fatty acid methyl ester ethoxylate is 5:2.

[0018] Preferably, the isomeric alcohol polyoxyethylene ether is selected from at least one of isomeric decanol polyoxyethylene ether, isomeric undecanol polyoxyethylene ether, and isomeric tridecanol polyoxyethylene ether.

[0019] Preferably, the isomeric alcohol polyoxyethylene ether includes isomeric tridecyl alcohol polyoxyethylene ether, which is from Guangzhou Dute Chemical Co., Ltd., model: TO-9.

[0020] Preferably, the fatty acid methyl ester ethoxylate is purchased from Guangzhou Canbo Chemical Co., Ltd., model: FMES.

[0021] In some preferred embodiments, the solvent is selected from one or a combination of propylene glycol monomethyl ether, isohexylene glycol, ethylene glycol monobutyl ether, ethylene glycol monoethyl ether, dipropylene glycol monobutyl ether, isopropanol, ethanol.

[0022] The applicant's research found that the solvent is selected from the combination of propylene glycol monomethyl ether and isohexylene glycol, and the weight ratio of propylene glycol monomethyl ether to isohexylene glycol is 1:(0.2 - 1). While improving the penetration of the kitchen cleaner, it can effectively reduce the residual odor. Propylene glycol monomethyl ether has both an ether group and a hydroxyl group in its molecular structure, effectively enhancing the compatibility with surfactants and water. However, too much propylene glycol monomethyl ether has too high a volatility. A certain proportion of isohexylene glycol increases the wettability of propylene glycol monomethyl ether and reduces the volatility rate. At the same time, isohexylene glycol has an extremely low surface tension, which can significantly improve the wetting performance of the product, help separate dirt and keep the dirt suspended, and can increase the solubility of stains such as aliphatic and aromatic hydrocarbons. Further research found that when the weight ratio of propylene glycol monomethyl ether to isohexylene glycol is 2:1, and the weight ratio of the surfactant to the degreaser is (7 - 10):1, the odor after using the kitchen cleaner can be further reduced, probably because the compatibility between systems is improved, while ensuring the oil penetration effect, reducing the addition amount of substances such as degreasers.

[0023] Preferably, the solvent is selected from the combination of propylene glycol monomethyl ether and isohexylene glycol.

[0024] Preferably, the weight ratio of propylene glycol monomethyl ether to isohexylene glycol is 1:(0.2 - 1).

[0025] More preferably, the weight ratio of propylene glycol monomethyl ether to isohexylene glycol is 2:1.

[0026] In some preferred embodiments, the degreaser is selected from at least one of sodium hydroxide and potassium hydroxide.

[0027] Preferably, the degreaser includes sodium hydroxide.

[0028] Preferably, the weight ratio of the surfactant to the solvent is 1:(0.3 - 0.8).

[0029] More preferably, the weight ratio of the surfactant to the solvent is 1:(0.4 - 0.7).

[0030] More preferably, the weight ratio of the surfactant to the solvent is 3:2.

[0031] Preferably, the weight ratio of the surfactant to the degreaser is (7-10):1.

[0032] More preferably, the weight ratio of the surfactant to the degreaser is 9:1.

[0033] The second aspect of the present invention provides a preparation method of an oil stain removing kitchen treasure, comprising the following steps:

[0034] Step 1: Weigh each raw material by mass percentage;

[0035] Step 2: Add the degreaser to water and stir until the solution is clear;

[0036] Step 3: Add the surfactant and the solvent to Step 2 and stir until the solution is clear to obtain the product.

[0037] Beneficial effects:

[0038] 1. The surfactant includes a combination of an anionic surfactant and a non-ionic surfactant. When the weight ratio of the anionic surfactant to the non-ionic surfactant is 1:(2-5), the detergency and stability can be improved, and at the same time, the addition amount of the surfactant can be reduced, and the production cost can be lowered.

[0039] 2. The solvent is selected from the combination of propylene glycol monomethyl ether and isocetyl alcohol, and the weight ratio of propylene glycol monomethyl ether to isocetyl alcohol is 1:(0.2-1). While improving the penetration power of the kitchen treasure, the residual odor can be effectively reduced, the environmental friendliness of the kitchen treasure can be improved, and the damage to the utensils can be effectively reduced.

[0040] 3. When the weight ratio of the surfactant to the degreaser is (7-10):1, the stability and detergency of the kitchen treasure can be improved.

[0041] 4. The non-ionic surfactant is selected from the combination of isomeric alcohol polyoxyethylene ether and fatty acid methyl ester ethoxylate. The weight ratio of isomeric alcohol polyoxyethylene ether to fatty acid methyl ester ethoxylate is 1:(0.2-1), which can further improve the penetration ability and effectively break down stubborn oil stains and dirt.
