Description

Technical Field

[0001] The invention relates to the technical field of cleaning products, in particular to a kitchen degreasing wet wipe and a preparation method thereof. Background Art

[0002] In modern kitchen cleaning, degreasing wipes are widely used as a convenient and fast cleaning tool for cleaning grease on surfaces such as stoves, range hoods, and kitchen countertops. However, existing kitchen degreasing wipes still have many shortcomings in terms of use effect and user experience, and further improvement and optimization are urgently needed.

[0003] Degreasing effect and environmental protection:

[0004] Most of the existing kitchen degreasing wipes rely on chemical surfactants. Although these chemical surfactants have certain effects in degreasing, most of them are not biodegradable and cause serious pollution to the environment. In addition, single chemical surfactants have limited effects in dealing with stubborn oil stains, and high concentrations of chemical ingredients are usually required to improve the degreasing ability, which not only increases the burden on the environment, but also poses a potential risk to user health. Therefore, how to improve the environmental friendliness of the product while ensuring efficient degreasing has become an important issue that needs to be solved urgently.

[0005] Solution distribution uniformity:

[0006] The traditional wet wipes production process mainly uses the common dipping method, that is, the non-woven fabric is immersed in the degreasing solution and then de-liquidated. However, this method often leads to uneven distribution of the degreasing solution in the non-woven fabric, affecting the cleaning effect. During the dipping process, there is a lack of effective technical means to ensure that the solution can evenly penetrate every part of the non-woven fabric, resulting in inconsistent cleaning effects when the wet wipes are used, which reduces the user experience. Therefore, it is particularly important to improve the production process of wet wipes and ensure the uniform distribution of the degreasing solution in the non-woven fabric.

[0007] Skin care effects:

[0008] Many existing degreasing wipes pursue a strong decontamination effect while neglecting to protect the user's skin. Wet wipes products come into direct contact with the skin during use, and long-term use may cause skin dryness, allergies and other problems. Existing degreasing products often lack effective skin care ingredients, or the types and proportions of skin care ingredients are insufficient, and cannot effectively alleviate the irritation of chemical ingredients to the skin. Therefore, how to add effective skin care ingredients to protect the user's skin while maintaining a strong decontamination effect is an important direction for product improvement.

[0009] Wet wipes moisturizing effect:

[0010] Existing wet wipes products often do not add effective humidity retaining agents during production and packaging, which causes the wet wipes to dry easily during storage and use, affecting the cleaning effect and service life. In addition, existing packaging materials and designs fail to fully consider the moisturizing needs of wet wipes, causing wet wipes to dry easily and requiring users to replace them frequently, thereby increasing the cost of use. Therefore, improving the formula and packaging design to enhance the moisturizing effect of wet wipes is the key to improving product practicality and user satisfaction.

[0011] Therefore, the present invention provides a kitchen degreasing wet wipe and a preparation method thereof to solve the deficiencies of the prior art. Summary of the invention

[0012] In view of the deficiencies in the prior art, the present invention provides a kitchen degreasing wet wipe and a preparation method thereof, which solves the problems in degreasing effect, environmental protection, solution distribution uniformity, skin care effect and moisturizing effect of the wet wipe.

[0030] Preferably, a method for preparing a kitchen degreasing wet wipe comprises the following steps:

[0031] a) preparing a degreasing solution: mixing a bio-based surfactant and a non-ionic surfactant at low temperature, and then sequentially adding a mixed organic solvent, a pH adjuster, a preservative, a thickener, a natural plant extract, an enzyme component, a skin care component and a fragrance at 40-50° C., stirring evenly to obtain a degreasing solution;

[0032] b) Wet wipes impregnation: Cut the non-woven fabric roll into the required size, and immerse the cut non-woven fabric into the prepared degreasing solution by pulse vacuum impregnation method for 1-2 hours;

[0033] c) Ultrasonic treatment: Ultrasonic treatment is performed during the immersion process to enhance the dispersibility and permeability of the degreasing components;

[0035] Preferably, the pulse vacuum impregnation method comprises the following steps:

[0036] i) placing the cut nonwoven fabric into a vacuum impregnation device;

[0037] ii) performing vacuum extraction at a vacuum degree of 0.06-0.08 MPa for 5-10 minutes;

[0038] iii) releasing the vacuum to allow the impregnation liquid to enter the nonwoven fabric, the release time being 5-10 minutes;

[0039] iv) Repeat steps ii and iii to ensure uniform distribution of the solution in the nonwoven fabric.

[0040] Preferably, the ultrasonic treatment comprises the following steps:

[0044] Preferably, the step of adding the humidity retaining agent comprises the following steps:

[0045] i) adding glycerol or propylene glycol to the degreasing solution in an amount of 1-3% of the total weight of the degreasing solution;

[0046] ii) After the degreasing solution is prepared, the humidity retaining agent is evenly stirred into the solution;

[0047] iii) The soaked wet wipes are packed in sealed packaging bags, ensuring that the humidity of the wet wipes is maintained at 70-80%.

[0048] The present invention provides a kitchen degreasing wet wipe and a preparation method thereof, which has the following beneficial effects:

[0050] 2. The present invention adopts a process combining pulse vacuum impregnation and ultrasonic treatment in the preparation process. In the pulse vacuum impregnation method, multiple vacuum suction and release are performed to allow the degreasing solution to penetrate into the non-woven fabric more evenly; ultrasonic treatment further enhances the dispersibility and permeability of the degreasing component during the impregnation process. Compared with the traditional impregnation method, the technical solution of the present invention significantly improves the uniform distribution of the degreasing solution in the wet wipes, solving the problem of uneven solution distribution in the prior art.

[0051] 3. The present invention adds skin care ingredients to the degreasing solution to effectively protect the user's skin and prevent dryness and allergies caused by frequent use of wet wipes. Compared with the formula of traditional degreasing products that do not consider skin care, the present invention introduces natural skin care ingredients, which not only ensures a strong degreasing effect, but also provides gentle care for the skin, solving the problem of high skin irritation in the prior art.

[0052] 4. The present invention adds a humidity retaining agent to the wet wipes package, so that the wet wipes can maintain appropriate humidity for a long time and avoid drying. The humidity retaining agent is added in an amount of 1-3% of the total weight of the degreasing solution, which can effectively extend the moisturizing time of the wet wipes. Compared with the problems of easy drying and short service life of wet wipes in the prior art, the technical solution of the present invention significantly improves the convenience and durability of wet wipes, and solves the problem of poor moisturizing effect of traditional wet wipes products.
