Description

Technical Field

[0001] The invention relates to the technical field of cleaning powder, and in particular to a cleaning element and a preparation method thereof. Background Art

[0002] As consumers' requirements for quality of life continue to increase, the fields of home cleaning and personal care have put forward higher requirements for the versatility, mildness and efficiency of cleaning products. Modern cleaning agents should not only have basic cleaning effects, but also have antibacterial, anti-mildew, deodorizing and other functions, while ensuring skin friendliness during use. Therefore, the development of a cleaning agent that has both cleaning ability and can meet the requirements of antibacterial, anti-mildew, deodorizing and other multiple functions has become an important trend in the current market.

[0003] Although existing cleaning products have made some breakthroughs in cleaning effects, there are still some technical bottlenecks, especially in terms of additional functions such as antibacterial, mildew prevention and deodorization, and they often face the following problems:

[0004] 1. Single efficacy: Most traditional cleaning agents focus on surface cleaning and lack effective antibacterial, anti-mildew and deodorizing ingredients. This means that consumers may need additional products to solve these problems during use, which increases the complexity and cost of use.

[0005] 2. Irritation problem: Some cleaning agents may irritate the skin due to the use of strong acid or alkaline ingredients, especially for users with sensitive skin, which may cause allergies or discomfort. Therefore, how to ensure the cleaning effect while avoiding skin irritation is a major challenge of existing technologies.

[0006] 3. The fragrance is not long-lasting: Although many cleaning agents have added fragrances, their fragrance is often short-lived and cannot keep the air fresh for a long time. In addition, some fragrance ingredients may cause certain irritation to the air and skin.

[0007] 4. Environmental friendliness: Some ingredients in traditional detergents may cause environmental pollution, especially to water and soil. Therefore, the development of a more environmentally friendly and degradable detergent has become an urgent issue to be solved. Summary of the invention

[0008] In order to make up for the deficiencies of cleaning agents in the prior art in terms of formula ingredients, antibacterial, mildew prevention, deodorization, etc., the present invention provides a cleaning agent and a preparation method thereof, aiming to provide a multifunctional, mild and effective cleaning agent, which has antibacterial, mildew prevention, deodorization and other effects, and is skin-friendly and suitable for wide use in home, skin care and other fields.

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

[0010] 1. A cleaning agent comprising the following raw materials in percentage by weight:

[0011] Surfactant 5%-15%;

[0012] Natural orange essential oil 1%-5%;

[0013] Antibacterial ingredients 2%-10%;

[0014] Anti-mildew ingredients 0.5%-2%;

[0015] Deodorant ingredients 0.5%-2%;

[0016] Other additives 0.5%-2%;

[0017] Solvent 70%-90%.

[0018] Preferably, the surfactant is sodium dodecyl sulfate, the pH value of the detergent is controlled between 4.5 and 6.5, and the content of the surfactant is 10%-12%.

[0019] Preferably, the antibacterial component is one or at least two of tea tree oil, citric acid and natural plant extracts; the anti-mildew component is one or two of gluconate and silver ions; and the deodorizing component includes activated carbon or phenolic compounds.

[0020] Preferably, the other additives include one or at least two of a stabilizer, a thickener or a humectant, and the solvent is water.

[0021] A method for preparing a cleaning agent comprises the following steps:

[0022] S1. Raw material preparation: prepare the raw materials according to the ratio, and mix the surfactant, natural orange essential oil, antibacterial agent, mildew inhibitor and deodorant according to the predetermined ratio;

[0023] S2. Heating and dissolving: heating the mixed solution to 60° C. to 80° C. to dissolve the components;

[0024] S3. Adjusting pH: adjusting the pH of the solution to 4.5 to 6.5;

[0025] S4, Filtration and filling: Remove impurities through high-precision filters and fill into clean containers for sealed packaging.

[0026] Preferably, the natural orange essential oil is extracted by cold pressing, and the extraction temperature is 20°C to 30°C. The extraction process includes selecting mature and healthy oranges, peeling and retaining the outer layer of the peel, washing and cutting into small pieces or breaking, using cold pressing equipment for mechanical pressing, and controlling the temperature between 20°C and 30°C to release the essential oil, and obtaining pure orange essential oil through separation and filtration.

[0027] Preferably, the acidic substance used to adjust the pH value is hydrochloric acid or acetic acid, and the alkaline substance is sodium hydroxide solution.

[0028] Preferably, the filtering step uses a high-precision filter with a filtering accuracy of not less than 0.5 microns to remove impurities and undissolved particles.

[0029] The application of the cleaning agent, especially applied to mosquito bites, flea bites or mite bites on the skin, is used to reduce the pain and itching on the skin and has good antibacterial and bactericidal effects.

[0030] The cleaning agent of the present invention has broad application prospects, can meet the dual needs of daily household cleaning and skin care, and has high market competitiveness.

[0031] Although there are many cleaning products on the market, there are still the following technical problems. The present invention innovates on this basis and solves these problems:

[0032] Insufficient antibacterial and anti-mildew functions: Traditional cleaning agents can only provide basic cleaning effects, and their ability to inhibit the growth of bacteria and mold is relatively weak. In the prior art, although some cleaning products claim to have certain antibacterial functions, most of them rely on chemical ingredients or antibacterial agents with too high concentrations, which can easily cause irritation to the skin or lead to drug resistance problems. The present invention uses natural plant extracts such as tea tree oil and citric acid, which have mild antibacterial and anti-mildew effects, and avoid the use of irritating ingredients, which can more effectively solve this technical problem.

[0033] The deodorizing effect is not lasting: Although many cleaning agents have the deodorizing function, the deodorizing effect is often not lasting, and the fragrance is easily lost during use. However, the natural orange essential oil in the present invention can not only effectively cover up the odor, but also provide a lasting fresh fragrance, improving the short-lived fragrance problem of existing products and improving user experience.

[0034] Poor skin friendliness: Existing cleaning products often use strong surfactants or acidic and alkaline substances when removing dirt and grease. These ingredients may cause damage to the skin, especially when used for a long time or in high concentrations, which may cause allergies, dryness and other problems. In contrast, the pH value of the cleaning agent in the present invention is controlled between 4.5 and 6.5, which can ensure its mildness and is suitable for a variety of skin types, avoiding the skin irritation that may be caused by traditional cleaning agents.

[0035] Environmental pollution: Some chemical components in traditional cleaning agents may cause environmental pollution, such as the use of chemical surfactants or harmful chemical preservatives that are not easily degraded, which have adverse effects on the environment. However, the present invention uses plant-derived ingredients such as natural orange essential oil and tea tree oil, which are not only natural and environmentally friendly, but also easy to degrade, thus avoiding environmental pollution.

[0036] Through the above technical scheme, the present invention provides a more gentle, efficient and environmentally friendly cleaning agent, which can not only meet the high demands of modern consumers for cleaning effects, but also provide additional functions such as deodorization, antibacterial and mildew prevention, and has broad market application prospects.

[0037] The present invention has the following beneficial effects:

[0038] 1. In the present invention, the cleaning ability of the product for stubborn stains is improved by improving the formula, the detergency is enhanced, the cleaning is ensured to be thorough, and the residue is reduced. The natural orange essential oil can add a natural fragrance to the product. At the same time, the addition of its antibacterial, anti-mildew and deodorizing ingredients improves the comprehensive cleaning effect of the cleaning agent, meeting the modern people's demand for high efficiency and mildness of cleaning products.

[0039] 2. In the present invention, the pH value of the cleaning agent is controlled within a skin-friendly range (4.5-6.5), ensuring that the product does not cause irritation to the skin when used, and is suitable for daily household cleaning and skin care.

[0040] 3. In the present invention, the cold pressing method is used to extract the orange essential oil during the preparation process, which maintains the natural components of the essential oil, retains its active ingredients to the greatest extent, and avoids the component loss that may be caused by high-temperature extraction.

[0041] 4. In the present invention, while removing dirt, it has multiple functions such as antibacterial, anti-mildew and deodorizing, which comprehensively improves the practicality of the product. The antibacterial ingredients, deodorizing ingredients and anti-mildew ingredients used in the product can effectively reduce the growth of bacteria and prevent the generation of mold and odor. It is particularly suitable for home cleaning, car air purification and skin care.

[0042] 5. In the present invention, environmentally friendly materials and ingredients are used to reduce pollution to the environment, while ensuring that the product is non-toxic and harmless, safe for human skin, improving cleaning efficiency, reducing use costs, and increasing economic benefits for users.
