Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of daily chemical products, in particular to a high-efficiency oil-removing tableware detergent and a preparation method thereof. BACKGROUND

[0002] With the progress of society and the improvement of people's living standards, the cleaning problem of tableware is increasingly concerned, especially in the catering industry and family life, there is a higher requirement for the cleaning effect of tableware. The oil removal effect is directly related to the sanitary condition of tableware, and also has an important influence on health and dining experience. Traditional tableware detergents usually rely on surfactants to remove oil stains. Although these detergents can clean surface grease to some extent, they generally have the following problems:

[0003] Most existing detergents use single or combined anionic and nonionic surfactants. These components dissolve oil through the hydrophilic and lipophilic groups of surfactants. However, due to the limitation of the molecular structure of surfactants, the efficiency of surfactants alone in dealing with stubborn oil stains or thick grease is not high, and it is difficult to meet the needs of high-grease tableware decontamination. In addition, surfactants often produce a large amount of foam during use, resulting in longer rinsing time, increased water consumption, which is not conducive to environmental protection and user experience, and also increases the skin irritation, making it difficult to achieve a good balance between cleaning effect and mildness.

[0004] In order to improve the decontamination ability, some detergents choose to increase the amount of surfactants or introduce special formulations, such as adding enzyme components to assist in degrading oil, or adding organic solvents to dissolve oil stains. However, these additives usually bring challenges to the cost, skin irritation, and stability of the formula, and the stability of enzymes and organic solvents is greatly affected by factors such as temperature and pH value, making it difficult to adapt to changing home and commercial environments.

[0005] Many existing detergents also have the problem of unstable solution and easy phase separation during storage, especially after low temperature or long time storage, which is easy to precipitate or stratify, affecting the appearance and use effect. This is because the compatibility and solubility between different components are limited, resulting in unstable formula structure, and most detergents lack enough thickening agent or stabilizer to maintain the uniformity of the liquid.

[0006] Therefore, it is necessary to develop a new technical scheme to solve the problems existing in the prior art and meet the development needs of the current market. SUMMARY

[0007] Based on this, the application provides a high-efficiency oil-removing tableware detergent to overcome the shortcomings of the prior art.

[0008] One object of the application is to provide a high-efficiency oil-removing tableware detergent, which comprises the following components in mass fraction:

[0009]

[0010] The modified sodium alginate is obtained by polymerization of allyl glycidyl ether modified sodium alginate, acrylic monomer and fatty alcohol polyoxyethylene ether acrylate.

[0011] Further, the anionic surfactant is selected from one or more of linear alkyl benzene sulfonic acid and its salt, fatty acid salt, alkyl sulfate, ethoxylated fatty alcohol sulfate, alpha-olefin sulfonate, sulfosuccinate, fatty acid alkyl ester sulfonate and ethoxylated fatty alcohol ether carboxylate.

[0012] Further, the nonionic surfactant is selected from one or more of EO / PO block polyether, fatty alcohol polyoxyethylene ether, secondary alcohol polyoxyethylene ether, fatty alcohol EO-PO block polyether and alkyl glycoside.

[0013] Further, the inorganic salt is selected from one or more of halide, carbonate, bicarbonate, formate, acetate, sulfate and citrate.

[0014] Further, the plant extract is selected from one or more of Roman chamomile extract, bergamot extract, geranium extract and aloe extract.

[0015] Further, the auxiliary agent is selected from one or more of preservative, pigment, essence, enzyme preparation, foam stabilizer and alkaline neutralizing agent.

[0016] The application also provides a preparation method of the high-efficiency oil-removing tableware detergent, which comprises the following steps:

[0017] S1, under inert gas protection, a crosslinking agent and an initiator are added to magnesium acrylate, and heated to react to obtain poly-magnesium acrylate;

[0018] S2, AEO9 and acrylic acid are blended, a catalyst is added, and vacuum heating is performed to react to obtain fatty alcohol polyoxyethylene ether acrylate;

[0019] S3, allyl glycidyl ether is added to a sodium alginate solution, and heated to react to obtain an intermediate product;

[0020] S4, blend acrylic acid, intermediate product, fatty alcohol polyoxyethylene acrylate, add emulsifier and initiator, heat reaction to obtain the modified sodium alginate;

[0021] S5, blend the modified sodium alginate, magnesium polyacrylate and other ingredients, stir uniformly to obtain the high-efficiency oil-removing dishwashing detergent.

[0022] Further, in step S2, the mass ratio of the AEO9 and the acrylic acid is 26-32:4-6.

[0023] Further, in step S3, the mass ratio of the sodium alginate and the allyl alcohol glycidyl ether is 0.8-1.2:1.

[0024] Further, in step S4, the mass ratio of the acrylic acid, intermediate product, fatty alcohol polyoxyethylene acrylate is 5-10:1-1.2:0.2-0.5.

[0025] The present application has the following beneficial effects:

[0026] The present application uses magnesium polyacrylate, modified sodium alginate, anionic surfactant and non-ionic surfactant for compounding, first, using AEO9 and acrylic acid as raw materials, under the action of catalyst and polymerization inhibitor, introducing acrylic acid segment with double bond to AEO9 to obtain fatty alcohol polyoxyethylene acrylate; second, using allyl alcohol glycidyl ether to modify sodium alginate, introducing allyl alcohol glycidyl ether with double bond into sodium alginate, and then performing polymerization reaction with acrylic acid monomer and fatty alcohol polyoxyethylene acrylate, so as to introduce polyoxyethylene ether type high molecular surfactant and polyacrylic acid high molecular segment into the modified sodium alginate, which can improve the dispersibility of the modified sodium alginate in the detergent and the compatibility of the modified sodium alginate with other components, thereby enhancing the stability of the detergent and avoiding the possibility of precipitation, deterioration and failure. The polyoxyethylene ether type high molecular surfactant segment in the modified sodium alginate not only improves the compatibility with the surfactant, but also has strong affinity with plant extracts such as Roman chamomile extract and other oxygen-containing active groups, which is beneficial to adsorption of active ingredients and promotion of dispersion effect, so that the active substances can be used for a long time. At the same time, the modified sodium alginate also has good compatibility with hydrophilic magnesium polyacrylate, so that various components can play a synergistic effect, further improving the detergency and redeposition of the detergent, and realizing rapid and efficient removal of oil stains.
