Description

Technical Field

[0001] The present invention relates to the field of detergents, and particularly to an electrolyzed water composition, a preparation method thereof, and an application thereof in detergents. Background Art

[0002] In the current field of cleaning products, with the improvement of people's living standards and the enhancement of environmental protection awareness, the performance requirements for detergents are becoming increasingly stringent. People not only expect it to efficiently remove various stains, but also require it to have a strong bactericidal function to ensure the hygiene and health of the cleaning environment. Among the many research directions for detergents, using new materials and composite formulations to improve product performance has become a key research hotspot, aiming to meet consumers' dual pursuits of cleaning effect and safety.

[0003] Traditional detergents usually mainly rely on surfactants to achieve the decontamination effect. Common anionic surfactants such as linear alkylbenzene sulfonic acid and its salts, alkyl sulfates, etc., and nonionic surfactants such as fatty alcohol alkoxylates, alkyl polyglycosides, etc. are widely used in the market. Some detergents also add some bactericides, such as chemically synthesized bactericides or natural plant extracts, but these components are often simply mixed and lack effective synergistic design.

[0004] Currently, there are many deficiencies in the detergents on the market. First, in terms of component compatibility, due to the differences in physical and chemical properties between different components, the dispersibility and uniformity are often poor, affecting the full play of the washing and bactericidal effects. Second, the stability of the bactericide in the system is poor, and it is easy to reduce its activity due to environmental factors or interaction with other components, resulting in a short bactericidal action time and difficulty in persistently and effectively inhibiting the growth of microorganisms. Third, the ability to remove stains is limited. Especially when facing some stubborn stains or complex combinations of pollutants, it is difficult to achieve an ideal cleaning effect. These problems seriously restrict the improvement of detergent performance, and there is an urgent need for new technical solutions to break through these bottlenecks to meet the market's demand for high-efficiency, safe, and multi-functional detergents.

[0005] In summary, there is an urgent need to develop a new technical solution to solve the problems existing in the prior art. Summary of the Invention

[0006] Based on this, the present invention provides an electrolyzed water composition, which contains components such as surfactants, electrolyzed water, plant extracts, and modified polyacrylic resins, and has excellent detergency and antibacterial properties. On the one hand, the modified polyacrylic resin has hydrophobic and hydrophilic groups, which can effectively improve the compatibility between components, enhance the dispersibility and uniformity of components, and improve the detergency and antibacterial effects; on the other hand, the modified polyacrylic resin has active groups such as polysaccharides, amino groups, and hydroxyl groups, which can adsorb electrolyzed water and plant extracts, enabling them to exist more stably in the composition and be continuously released, so that the instantaneous strong bactericidal effect of electrolyzed water and the slow-release antibacterial effect of plant components form a complement, enhancing the synergistic effect of the two and prolonging their antibacterial action time, thereby enhancing the antibacterial effect; at the same time, the amphiphilic modified polyacrylic resin can also synergistically enhance the efficiency with anionic and non-ionic surfactants, enhancing the ability to remove various pollutants and further enhancing the washing and detergency effects. In addition, the high pH value of electrolyzed water and its negative oxidation-reduction potential (ORP is -900 mV to -1200 mV) characteristics can effectively decompose the organic matter structure through saponification reaction and destroy the cell membrane potential of microorganisms, forming a dual detergency mechanism with the emulsification and penetration effects of surfactants, further enhancing the detergency effect; the active hydrogen radicals generated by its strong reducibility and the natural antibacterial substances in plant extracts produce an oxidation-reduction synergistic effect, further enhancing the antibacterial effect.

[0007] An object of the present invention is to provide an electrolyzed water composition, comprising raw materials in the following parts by mass:

[0008]

[0009] Wherein,

[0010] The modified polyacrylic resin is obtained by blending an alkyl acrylate, polyethylene glycol diacrylate and hydroxyacrylate copolymer with hydroxylated graphene, modifying with epichlorohydrin, and then reacting with chitosan.

[0011] Further, the surfactant is selected from one or more of anionic surfactants or non-ionic surfactants.

[0012] Further, the anionic surfactant is selected from one or more of linear alkylbenzene sulfonic acid and its salts, fatty acids and their salts, alkyl sulfates, ethoxylated fatty alcohol sulfates, α-olefin sulfonates, sulfosuccinates, fatty acid alkyl ester sulfonates or ethoxylated fatty alcohol ether carboxylates.

[0013] Further, the non-ionic surfactant is selected from one or more of fatty alcohol alkoxylates, alkyl polyglycosides, fatty acid alkoxylates, fatty acid ethoxylates, fatty acid methyl ester ethoxylates, fatty acid alkyl alkanolamides, ethoxylated sorbitan fatty acid esters or polyether surfactants.

[0014] Further, the electrolyzed water is alkaline electrolyzed water. Alkaline electrolyzed water is produced when water is electrolyzed. When an electric current passes through water (H2O), hydrogen gas is generated at the cathode, and positively charged ions move towards the cathode, resulting in the formation of alkaline electrolyzed water at the cathode. Its oxidation-reduction potential is around -900 mV, and the pH value can reach 11.5. It has sufficient alkalinity and strong reducing ability, which can effectively dissolve grease and emulsify it, thus removing the grease from the surface of the object and achieving the effect of degreasing and decontaminating. At the same time, due to its relatively high pH value, alkaline electrolyzed water can hydrolyze the proteins and nucleic acids of pathogenic bacteria, disrupt the normal metabolic functions of bacteria, and cause bacteria to die, with a strong bactericidal effect.

[0015] Further, the plant extract component is selected from one or more of grapefruit seed extract, honeysuckle extract, oregano oil, natural bamboo vinegar concentrate, gallic acid, thymol, camphor oil, ginger extract, garlic essential oil, white willow bark extract, clove extract, cinnamon oil, lemon oil, tea tree oil, or mugwort oil.

[0016] Further, the pH regulator is sodium bicarbonate.

[0017] Further, the raw materials of the electrolyzed water composition further include other bactericides.

[0018] Further, the other bactericides are selected from one or more of cationic quaternary ammonium salt surfactants, parachlorometaxylenol, o-phenylphenol and its salts, o-cymene-5-ol, or piroctone olamine.

[0019] Another object of the present invention is to provide a method for preparing the above electrolyzed water composition, comprising the following steps:

[0020] S1. Blend alkyl acrylate, polyethylene glycol diacrylate, and hydroxy acrylate, add an initiator, and heat for a polymerization reaction to obtain a polyacrylic acid resin;

[0021] S2. Blend the polyacrylic acid resin, hydroxylated graphene, and epichlorohydrin, and heat and react under acidic conditions to obtain an intermediate product;

[0022] S3. Blend the intermediate product with chitosan, and heat and stir under alkaline conditions to obtain a modified polyacrylic acid resin;

[0023] S4. Mix all components evenly to obtain the electrolyzed water composition.

[0024] Further, in step S1, the mass ratio of the alkyl acrylate, polyethylene glycol diacrylate, and hydroxy acrylate is (1 - 5):(5 - 15):(3 - 10).

[0025] Further, in step S2, the mass ratio of the polyacrylic resin, hydroxylated graphene, and epichlorohydrin is (10 - 20):(0.5 - 1.5):(15 - 30).

[0026] Further, in step S3, the mass ratio of the intermediate product to chitosan is (1 - 5):(30 - 50).

[0027] Further, in step S1, the heating temperature is 60 - 80°C.

[0028] Further, in step S2, the heating temperature is 40 - 60°C.

[0029] Further, in step S3, the heating temperature is 30 - 50°C.

[0030] Another object of the present invention is to provide the application of the above electrolyzed water composition in detergents.

[0031] The present invention has the following beneficial effects:

[0032] The present invention provides an electrolyzed water composition, which contains components such as surfactants, electrolyzed water, plant extracts, and modified polyacrylic resins, and has excellent detergency and antibacterial properties. On the one hand, the modified polyacrylic resin has hydrophobic and hydrophilic groups, which can effectively improve the compatibility between components, enhance the dispersibility and uniformity of components, and improve the detergency and antibacterial effects; on the other hand, the modified polyacrylic resin has active groups such as polysaccharides, amino groups, and hydroxyl groups, which can adsorb electrolyzed water and plant extracts, enabling them to exist more stably in the composition and be continuously released, making the instantaneous strong bactericidal effect of electrolyzed water and the slow-release antibacterial effect of plant components complementary, enhancing the synergistic effect of the two, and prolonging the antibacterial action time, thereby enhancing the antibacterial effect; at the same time, the amphiphilic modified polyacrylic resin can also synergistically enhance the efficiency with anionic and non-ionic surfactants, enhancing the ability to remove various pollutants and further enhancing the washing and detergency effects. In addition, the high pH value of electrolyzed water and its negative oxidation-reduction potential (ORP is -900 mV to -1200 mV) characteristics can effectively decompose the organic matter structure through saponification reaction and destroy the cell membrane potential of microorganisms, forming a dual detergency mechanism with the emulsification and penetration effects of surfactants, further enhancing the detergency effect; the active hydrogen radicals generated by its strong reducibility and the natural antibacterial substances in plant extracts produce an oxidation-reduction synergistic effect, further enhancing the antibacterial effect.
