Description

Technical Field

[0001] The invention relates to the technical field of daily chemical products, in particular to a high-efficiency oil-removing dishwashing detergent and a preparation method thereof. Background Art

[0002] With the progress of society and the improvement of people's living standards, the cleaning of tableware has received increasing attention, especially in the catering industry and family life, where higher requirements are placed on the cleaning effect of tableware. The effect of removing oil stains is directly related to the hygiene of tableware, and also has an important impact on health and dining experience. Traditional dishwashing detergents usually rely on surfactants to remove oil stains. Although these detergents can clean surface grease to a certain extent, they generally have the following problems:

[0003] Existing detergents mostly use single or combined anionic and nonionic surfactants, which dissolve grease through the hydrophilic and lipophilic group structures of surfactants. However, since the decontamination effect of surfactants is limited by their molecular structure, surfactants alone are not efficient in dealing with stubborn grease or heavy grease, and it is difficult to meet the decontamination needs of high-fat tableware. In addition, surfactants often produce a lot of foam during use, which leads to longer rinsing time and increased water consumption, which is not good for environmental protection and user experience. This will also increase skin irritation, making it difficult to achieve a good balance between cleaning effect and mildness.

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

[0005] Many existing detergents still have problems with unstable solutions and easy phase separation during storage, especially after being stored at low temperatures or for a long time, precipitation or stratification is likely to occur, affecting the appearance and use effect. This is because the compatibility and solubility between different ingredients are limited, resulting in an unstable formula structure, and most detergents lack sufficient thickeners or stabilizers to maintain the uniformity of the liquid.

[0006] Therefore, it is very necessary to develop a new technical solution to solve the problems of existing products and meet the development needs of the current market. Summary of the invention

[0007] Based on this, the present invention provides a highly efficient degreasing dishwashing detergent to overcome the deficiencies of the prior art. The detergent of the technical solution adds magnesium polyacrylate and modified sodium alginate, which can work together with other ingredients to effectively improve the decontamination effect and effectively solve the problem of detergent stability, ensuring that the detergent remains clear and does not stratify during storage.

[0008] One object of the present invention is to provide a highly efficient degreasing dishwashing detergent, wherein the highly efficient degreasing dishwashing detergent has the following components by mass fraction:

[0009]

[0010] The modified sodium alginate is obtained by polymerizing sodium alginate modified with allyl alcohol glycidyl ether with acrylic acid monomer and fatty alcohol polyoxyethylene ether acrylate.

[0011] Furthermore, the anionic surfactant is selected from one or more of linear alkylbenzene sulfonic acid and its salts, fatty acid salts, alkyl sulfates, ethoxylated fatty alcohol sulfates, α-olefin sulfonates, sulfosuccinates, fatty acid alkyl ester sulfonates and ethoxylated fatty alcohol ether carboxylates.

[0012] Furthermore, 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] Furthermore, the inorganic salt is selected from one or more of halides, carbonates, bicarbonates, formates, acetates, sulfates, and citrates.

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

[0015] Furthermore, the auxiliary agent is selected from one or more of preservatives, pigments, flavors, enzyme preparations, foam stabilizers, and alkaline neutralizers.

[0016] The present invention also provides a method for preparing the highly efficient oil-removing dishwashing detergent, comprising the following steps:

[0017] S1. Under the protection of inert gas, a crosslinking agent and an initiator are added to magnesium acrylate, and the mixture is heated for reaction to obtain magnesium polyacrylate;

[0018] S2, blending AEO9 and acrylic acid, adding a catalyst, and heating in vacuum to react to obtain fatty alcohol polyoxyethylene ether acrylate;

[0019] S3, adding allyl alcohol glycidyl ether to the sodium alginate solution, heating for reaction, and obtaining an intermediate product;

[0020] S4, blending acrylic acid, the intermediate product, and fatty alcohol polyoxyethylene ether acrylate, adding an emulsifier and an initiator, and heating to react to obtain the modified sodium alginate;

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

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

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

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

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

[0026] The invention adopts magnesium polyacrylate, modified sodium alginate, anionic surfactant and nonionic surfactant for compounding. Firstly, AEO9 and acrylic acid are used as raw materials, and under the action of a catalyst and a polymerization inhibitor, an acrylic acid segment with a double bond is introduced into AEO9 to obtain fatty alcohol polyoxyethylene ether acrylate; secondly, allyl alcohol glycidyl ether is used to modify the sodium alginate, and the allyl alcohol glycidyl ether with a double bond is introduced into the sodium alginate, and then polymerization reaction is carried out with acrylic acid monomer and fatty alcohol polyoxyethylene ether acrylate, so that polyoxyethylene ether type polymer surfactant and polyacrylic acid polymer segment are introduced into the modified sodium alginate, the dispersibility of the modified sodium alginate in the detergent and the compatibility of the modified sodium alginate with other components are improved, so as to enhance the stability of the detergent and avoid the possibility of precipitation, deterioration and failure. The polyoxyethylene ether type polymer surfactant chain segment in the modified sodium alginate not only improves the compatibility with surfactants, but also the introduced polysaccharides and oxygen-containing active groups have strong affinity with plant extracts such as Roman chamomile extract, which is beneficial to the adsorption of active ingredients and promotes the dispersion effect, making the active substances effective for a long time. At the same time, the modified sodium alginate also has good compatibility with hydrophilic magnesium polyacrylate, so that multiple components can play a synergistic role, further improving the detergent's decontamination ability and stain redeposition, and realizing the rapid and efficient removal of oil stains.
