Description

Technical Field

[0001] The invention relates to the technical field of daily chemical products, and in particular to a cleaning composition and application thereof on wet wipes. Background Art

[0002] Wet wipes are made of liquid medicine and base cloth in a certain proportion and packaged by packaging materials. There are many types of liquid medicine, such as those with cleaning, sterilization, disinfection, cooling and other functions; there are also many types of base cloth, the more common ones are all-viscose cloth, viscose polyester cloth, wet-strength paper, pure cotton cloth, etc. With the development of the wet wipes market, consumers' demand for wet wipes is becoming increasingly diversified, and companies' innovations in new products, new technologies and new packaging are also becoming more and more diversified. Kitchen wipes are an indispensable cleaning product in modern family life. However, kitchen wipes are different from general human wipes. Kitchen wipes have higher requirements for the cleaning power of oil stains. The liquid medicine formula often adds more surfactants and functional additives to achieve the effect of cleaning oil stains. From a technical point of view, the following three types of kitchen cleaning products are more common:

[0003] The first type is the strong acid and strong alkali type. They have a good ability to remove heavy oil dirt by hydrolyzing grease. However, due to their strong acidity or alkalinity, they will cause great damage to the user's hand skin. Therefore, the user needs to wear gloves when using them to clean, which is very inconvenient. In addition, strong acid and strong alkali kitchen cleaning products have a certain degree of corrosion to the metal surface of the utensils, which can easily cause damage to the surface of the utensils and affect the appearance.

[0004] The second type is solvent-based, such as ethylene glycol butyl ether, propylene glycol butyl ether and other ether organic solvents. Solvent-based kitchen cleaning products mainly use organic solvents to wet, penetrate, and dissolve oil stains to remove and remove oil stains. However, these organic solvents may dissolve the painted surface or printed parts of kitchen utensils and destroy the surface pattern effect. In addition, some organic solvents are volatile low-toxic substances with pungent odors. After use, they will cause a certain degree of air pollution to the home environment, which is inconsistent with the modern people's pursuit of safe and environmentally friendly life concepts.

[0005] The third type is a pure surfactant formula, which gives full play to the penetration, emulsification and solubilization of surfactants to remove oil stains. This type of product is difficult to implement in terms of formulation technology, and usually has poor detergency, complex formulations, and high costs. In addition, kitchen cleaning products with pure surfactants will produce a lot of foam during use, which will increase the number of rinsing times and waste a lot of water.

[0006] Chinese patent application No. 201610562775.7 discloses a kitchen wet wipes soaking liquid and its preparation method and application. The kitchen wet wipes soaking liquid is prepared from raw materials including the following components by mass percentage: rheology modifier 0.01% to 0.2%, surfactant composition 1% to 10%, bactericidal preservative 0% to 1.5%, chelating agent 0% to 5%, defoaming agent 0% to 0.1%, essence 0% to 0.2%, and the balance is water; the rheology modifier is an acrylic acid (ester) cross-linked copolymer with a molecular weight of 1.0×108 to 1.0×1010 Dalton; the surfactant composition is a mixture of alkyl glycoside, alkyl amide propyl betaine, and alkyl amide propyl amine oxide in a mass ratio of 10 to 1:5 to 1:1. The kitchen wet wipes soaking liquid of the invention solves the problem of easy sedimentation of the contents of the wet wipes, improves the stability of the product, and has high efficiency in decontamination, safety and mildness. However, the wet wipes require bactericidal preservatives and other functional additives in the liquid, which results in a high production cost and does not have the function of absorbing dirt and odor.

[0007] Chinese patent application No. 202011158021.8 discloses a cleaning composition and cleaning wipes, which include the following components by weight percentage: 0.1%-15% of a compound surfactant, 0.1%-15% of a nonionic surfactant, 0.05%-10% of an amphoteric surfactant, 0.1%-30% of a chelating agent, and 0.001%-10% of a deodorant; wherein the compound surfactant includes at least one of MF EH and G12. After washing and wiping, the cleaning composition and cleaning wipes of the invention can easily clean the components attached to the surface without leaving spots and water marks, have strong decontamination power, can also play a role in sterilization, and do not corrode metal surfaces such as knives and cookers. However, the cleaning composition does not have the function of absorbing dirt and odors. Summary of the invention

[0008] Therefore, in view of the above problems, the present invention provides a cleaning composition and its application in wet wipes, which solves the problems that existing cleaning wet wipes do not have strong friction, poor cleaning effect, and do not have the function of absorbing dirt and odor.

[0009] To achieve the above object, the present invention adopts the following technical solutions:

[0010] A cleaning composition comprises the following raw materials in percentage by mass: 0.1%-15.0% of polyoxyethylene alcohol ether nonionic surfactant, 0.1%-15.0% of polyoxyethylene lauric acid amide, 2.0%-8.0% of 2-methyl-2,4-pentanediol, 0.1%-2.0% of modified amine oxide amphoteric surfactant, 0.1%-2.0% of isomeric alcohol polyoxyethylene ether, 0.1%-2.0% of protease, 0.1%-2.0% of cellulase, 1.0%-10.0% of activated carbon powder, 0.1%-2.0% of thickener, 0.1%-5.0% of preservative, and the balance is deionized water.

[0011] Furthermore, the structural formula of the modified amine oxide amphoteric surfactant is shown in formula (1):

[0012]

[0013] Wherein, R is an alkyl group with a number of 1-4; the preparation of the modified amine oxide amphoteric surfactant is as follows:

[0014] I. Placing a catalyst in a reaction kettle, adding a short-chain fatty alcohol, adjusting the flow rates of hydrogen and ammonia, and reacting to obtain a short-chain alkyl primary amine; the synthesis process of the short-chain alkyl primary amine is shown in formula (2):

[0015]

[0016] II. Add the short-chain alkyl primary amine obtained in step I into the reactor, introduce ethylene oxide gas, adjust the pressure in the reactor to 0.2-0.4 MPa, increase the temperature to 110-120° C., and react for 2-4 hours to obtain a short-chain alkyl dihydroxyethyl tertiary amine; the synthesis process of the short-chain alkyl dihydroxyethyl tertiary amine is shown in formula (3):

[0017]

[0018] III. Add 10-30 parts by weight of deionized water to the short-chain alkyl dihydroxyethyl tertiary amine obtained in step II, raise the temperature to 60-70° C., add 0.01-0.1 parts by weight of H2O2 solution dropwise under stirring, raise the temperature to 80-90° C. after the addition is complete, stir and react for 3-4 hours to obtain a first mixture, extract the first mixture with the extract for 3-5 times, then remove moisture with a rotary evaporator, vacuum dry for 24-48 hours, and then recrystallize with acetone for 3-5 times to obtain a modified amine oxide amphoteric surfactant; the synthesis process of the modified amine oxide amphoteric surfactant is shown in formula (4):

[0019]

[0020] Furthermore, the particle size of the activated carbon powder is 15-30 microns.

[0021] Furthermore, the extract is a mixture of petroleum ether and ethyl acetate, the mass fraction of the petroleum ether is 90-95%, and the mass fraction of the ethyl acetate is 10-15%.

[0022] Furthermore, the mass fraction of the H2O2 solution is 5-10%.

[0023] Furthermore, the vacuum drying temperature is 80-90°C.

[0024] Application of a cleaning composition on wet wipes comprises the following steps:

[0025] S1. Preparation of raw materials: including polyester fiber, viscose fiber and cleaning composition;

[0026] S2. Preparation of C-shaped fibers: The raw polyester fibers are passed through a C-shaped or concave spinneret and melt-spinned to obtain C-shaped fibers;

[0027] S3, preparation of nonwoven fabric: combing the C-shaped fibers and viscose fibers, passing them through a gravity oscillating screen before laying the web, so that the openings of the C-shaped fibers face upward, and then laying the web to form a nonwoven fabric;

[0028] S4, adding liquid: applying the cleaning composition evenly to the front side of the nonwoven fabric, transmitting it to the pressure sheet via a conveyor belt, reinforcing the embedding of the activated carbon powder, and obtaining a rough wet wipes product;

[0029] S5, cutting and packaging the wet wipes crude product obtained in step S4 to obtain wet wipes.

[0030] Furthermore, the opening diameter of the C-shaped fiber is 12-20 microns.

[0031] Furthermore, the C-shaped fiber openings on the front side of the nonwoven fabric face upward.

[0032] Furthermore, the quantitative ratio of the polyester fiber to the viscose fiber is 1:2-3.

[0033] By adopting the above technical solution, the beneficial effects of the present invention are:

[0034] 1. Anionic surfactants are commonly used in detergents as the main cleaning factor, and cationic surfactants are used as preservatives and bactericidal substances. Anionic surfactants have strong cleaning power, but they conflict with cationic surfactants and are prone to flocculation; therefore, to have a cleaning function, it is necessary to add preservatives and bactericidal agents, but this will increase costs; at the same time, anionic surfactants are more irritating. Therefore, the cleaning composition of the present application does not adopt the traditional formula system, but adopts polyoxyethylene alcohol ether nonionic surfactants and modified amine oxide amphoteric surfactants, which are reasonably matched and can also achieve better detergency. And the polyoxyethylene alcohol ether nonionic surfactant is compounded with polyoxyethylene lauric acid amide, which not only has good water solubility and strong foaming power, but also has strong foam stability and cleaning power. At the same time, it has a certain thickening effect on the system, which can disperse the activated carbon powder more evenly and avoid the agglomeration of the activated carbon powder.

[0035] 2. Using short-chain fatty alcohols as raw materials, a short-chain alkyl primary amine is prepared by catalytic amination at normal pressure in one step, and then a short-chain alkyl dihydroxyethyl tertiary amine is prepared to finally obtain a modified amine oxide amphoteric surfactant. The overall process is simple, no toxic substances are introduced, and the synthetic route is green and environmentally friendly.

[0036] 3. The prepared modified amine oxide amphoteric surfactant has increased hydrophilicity due to the introduction of ethylene oxide groups. It has good wettability and good water solubility. It is resistant to strong acids and alkalis, and exhibits multiple advantages such as solubilization, emulsification, foam stabilization, softening, moisturizing and antistatic. It has extremely low physiological activity, is easily biodegradable, does not irritate the skin, and has a good hand feel.

[0037] 4. After adding liquid to the C-shaped fiber with the opening facing upward, the activated carbon powder falls into the opening of the C-shaped fiber, and then is pressed down from top to bottom by the pressure plate to reinforce the embedding of the activated carbon powder. The added activated carbon powder has a good effect of absorbing dirt and odor, and its solid particles can increase the friction of the wet wipes, which can achieve a good physical cleaning effect.
