Description

Technical Field

[0001] This invention belongs to the field of cleaning technology, specifically relating to a gel-based oil stain remover. Background Technology

[0002] With the improvement of people's living standards and housing conditions, the use of kitchen degreasers is becoming increasingly widespread and the amount used is also increasing. Consequently, the quality requirements for degreasers are also rising. Traditional degreasers have many pain points that consumers urgently need to address, such as the difficulty in removing stubborn kitchen grease. When cleaning the top and sides of a kitchen range hood, traditional degreasers, whether sprayed as a mist or foam, will drip liquid, causing stains on the stovetop. Furthermore, when cleaning vertical walls, the liquid will run down, resulting in short contact time between the product and the grease on the vertical surface and significantly reduced effectiveness. Therefore, the market urgently needs a kitchen degreaser that does not drip when sprayed on vertical or non-flat hard surfaces, allowing the liquid to quickly wet and penetrate the grease, shortening the waiting time and quickly cleaning the grease.

[0003] Chinese patent CN118562563A discloses a long-lasting alkaline kitchen grease cleaner and its preparation process. However, the thixotropic agent, hydrophilic silica, acrylic-acrylate copolymer, cellulose ether, xanthan gum, and bentonite used in the patent all affect the spraying state of the kitchen grease cleaner. It can either not spray out or can only spray out liquid in a broken, linear pattern instead of spreading out in a mist. Lithium magnesium silicate sprays out slightly better, but the surface of the resulting kitchen cleaner is prone to water precipitation, resulting in an unstable state. Therefore, the market urgently needs a kitchen grease cleaner with superior performance. Summary of the Invention

[0004] To solve the above problems, the present invention provides a gel oil stain remover that, whether sprayed as a mist or a mesh foam, will not drip on vertical surfaces and will be instantly fixed.

[0005] The technical solution provided by this invention is as follows: A gel-based oil stain remover comprises the following ingredients by weight percentage: Thickening and fixing agent: 0.5%-2%, microcrystalline cellulose; Surfactants: are a blend of anionic and nonionic surfactants, wherein the anionic surfactant is 3% to 6% and the nonionic surfactant is 1% to 3%; Alkaline auxiliaries: 1.6% to 5.1%, comprising at least one of triethanolamine and sodium hydroxide; Solvent: 5% to 7%, is at least one of isohexyl glycol, diethylene glycol butyl ether, and dipropylene glycol methyl ether; Chelating agent: 0.1%, disodium ethylenediaminetetraacetate; The remaining portion is deionized water.

[0006] In some embodiments, the anionic surfactant is sodium fatty alcohol polyoxyethylene ether sulfate; The nonionic surfactant is fatty alcohol polyoxyethylene ether-9.

[0007] In some embodiments, the microcrystalline cellulose has a particle size of 20–50 nm.

[0008] In some embodiments, the solvent is isohexyl glycol and diethylene glycol butyl ether.

[0009] In some embodiments, the pH value of the cleaning gel is 10-12.

[0010] In some implementations, the following components by weight percentage are included: Thickening and fixing agent: 1.5% microcrystalline cellulose; Anionic surfactant: 5%, sodium fatty alcohol polyoxyethylene ether sulfate; Nonionic surfactant: 2%, which is fatty alcohol polyoxyethylene ether-9; Alkaline additives: 2% triethanolamine and 0.5% sodium hydroxide; Solvent: 1% isoxaconitol and 4% diethylene glycol butyl ether; Chelating agent: 0.1%, disodium ethylenediaminetetraacetate; On the other hand, a method for preparing a gel-based oil stain remover, comprising the following steps: S1: Add deionized water to a mixing bowl and stir at low speed. Add disodium ethylenediaminetetraacetate until dissolved. S2: Slowly add microcrystalline cellulose and homogenize at high speed (5000 rpm) for 30 minutes until dispersed into a translucent gel. S3: Add the anionic surfactant, nonionic surfactant and solvent in sequence, and stir until dissolved; S4: Add alkaline additives to adjust the pH to 10-12, add water to maintain a constant mass, and stir at low speed to homogenize.

[0011] In summary, the beneficial effects of this invention are: The thickener in this invention is microcrystalline cellulose, which has wall-adhesive properties. When used, whether sprayed as a mist or a mesh foam, the liquid will not flow on a vertical surface and will be instantly fixed, allowing the liquid to fully contact the oil stains, especially resinous old oil stains, which require a certain amount of time to be fully removed, thus greatly improving the effect. Detailed Implementation

[0012] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. The following embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0013] This invention provides a gel-based oil stain remover, comprising the following ingredients by weight percentage: Thickening and fixing agent: 0.5%-2%, microcrystalline cellulose; Surfactants: are a blend of anionic and nonionic surfactants, wherein the anionic surfactant is 3% to 6% and the nonionic surfactant is 1% to 3%; Alkaline auxiliaries: 1.6% to 5.1%, comprising at least one of triethanolamine and sodium hydroxide; Solvent: 5% to 7%, is at least one of isohexyl glycol, diethylene glycol butyl ether, and dipropylene glycol methyl ether; Chelating agent: 0.1%, disodium ethylenediaminetetraacetate; The remaining portion is deionized water.

[0014] Among them, microcrystalline cellulose fibers have a large aspect ratio and strong hydrophilicity, which can form honeycomb-like channels in the aqueous phase, thereby improving the viscoelasticity of the system. The microcrystalline cellulose in this application is produced by Nippon Paper Corporation and is a material that processes wood fibers to the nanoscale.

[0015] In a preferred embodiment, the particle size is controlled at 20-50 nm, which can significantly improve atomization uniformity and reduce sedimentation rate. Compared with xanthan gum and bentonite, microcrystalline cellulose does not contain charged groups, has good compatibility with surfactant systems, and does not flocculate with anionic / nonionic surfactants; it also has excellent resistance to electrolytes and alkalis.

[0016] The anionic surfactant is sodium fatty alcohol polyoxyethylene ether sulfate (AES). AES has excellent foaming and wetting abilities and can quickly reduce the surface tension of oil stains. Its anionic head groups completely dissociate in an alkaline environment, exhibiting excellent emulsification effects on fatty acid glycerides.

[0017] The nonionic surfactant is fatty alcohol polyoxyethylene ether-9 (AEO-9). The lipophilic segments of AEO-9 interact fully with stubborn resin scale. When combined with AES, it can form hydrophobic association microdomains, enhancing intermolecular synergistic decontamination.

[0018] In this application, the solvent (isohexanediol / diethylene glycol butyl ether / dipropylene glycol methyl ether 5–7 wt%), the total amount of which is limited to ≤7 wt%, is used to reduce odor burden and meet low VOC requirements.

[0019] The core innovation of this gel-based oil stain remover lies in its use of microcrystalline cellulose to create a three-dimensional network framework, stably encapsulating highly effective surfactants, mild alkalis, and low-odor solvents within it, thus balancing smooth spraying and good adhesion to the spray bottle. Furthermore, by precisely controlling the content of microcrystalline cellulose, this invention ensures adhesion to the spray bottle while avoiding problems such as nozzle clogging or uneven atomization.

The detergency testing method is as follows: For comparative testing, an equal amount of viscous grease from a kitchen range hood was applied to a stainless steel plate, placed in a 45℃ oven for 24 hours of aging, cooled, and then placed vertically on a test surface. Grease gel was sprayed onto the grease in the same manner, and the time was recorded. The detergency was evaluated based on the amount of grease residue remaining.

Table 1 As can be seen from the test results in Table 1, the formulations in Examples 1–5 have a reasonable structure and balanced performance, demonstrating the wide adaptability and unique advantages of microcrystalline cellulose in gel-type kitchen degreasers, and possessing value for industrial mass production and market promotion.

[0045] Oil stain remover made with other thickeners such as sorbitol, xanthan gum, and magnesium aluminum silicate sprays does not spray smoothly onto vertical surfaces, failing to hold its shape and tending to flow. In terms of stability, oil stain removers using microcrystalline cellulose, sorbitol, and xanthan gum as thickeners exhibit good stability, while those using magnesium lithium silicate as a thickener show poor stability. It is particularly noteworthy that Example 1 exhibits the best overall performance, and its formulation can serve as an optimal process reference.

[0046] Comparative Examples 1–3 clearly demonstrate the key shortcomings of traditional thickeners in spray products, such as insufficient wall adhesion, difficulty in spraying, and poor stability, thus verifying the innovation and necessity of this invention.
