Description

Technical Field

[0001] This invention relates to the field of laundry detergent technology, specifically to an environmentally friendly antibacterial laundry detergent and its preparation method. Background Technology

[0002] Laundry detergent is an essential cleaning product in modern households. With increasing health and environmental awareness, higher demands are being placed on the performance of laundry detergents. Traditional laundry detergents, in order to achieve powerful cleaning and antibacterial effects, typically contain phosphorus, chlorine bleach, optical brighteners, and chemically synthesized antibacterial agents. These ingredients are discharged into the environment with wastewater after washing, are difficult to degrade naturally, easily cause eutrophication of water bodies, damage aquatic ecosystems, and may accumulate in organisms through the food chain, posing a potential threat to the environment and human health. Furthermore, long-term use of chemically synthesized antibacterial agents can easily lead to drug resistance in microorganisms, reducing their antibacterial effectiveness and potentially disrupting the normal flora balance on the surface of human skin.

[0003] To address these issues, some laundry detergents marketed with "green" or "natural" concepts have emerged. However, these products often suffer from the following shortcomings: First, they have a narrow antibacterial spectrum and unsatisfactory antibacterial effects, especially against many common pathogenic bacteria; second, they sacrifice cleaning power in pursuit of natural and environmentally friendly products, resulting in cleaning performance that fails to meet daily needs; and third, the synergy among the components in the product formula is poor, leading to poor product stability or easy deactivation of natural active ingredients.

[0004] Therefore, developing a laundry detergent that can effectively remove dirt, has broad-spectrum and highly effective antibacterial activity, and is also biodegradable and environmentally friendly has significant practical importance and market value. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned technical difficulties and provide an environmentally friendly antibacterial laundry detergent and its preparation method. The prepared laundry detergent uses antibacterial ingredients from natural sources and environmentally friendly surfactants, which have both excellent cleaning ability and broad-spectrum antibacterial properties, and are environmentally friendly and gentle on the human body.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0007] An environmentally friendly antibacterial laundry detergent comprises the following components: surfactant, natural antibacterial agent, environmentally friendly detergent builder or chelating agent, thickener, pH adjuster, plant essential oil, biological enzyme preparation, solubilizer, and the balance being deionized water.

[0008] Furthermore, it includes the following components by weight percentage: 10-40% surfactant, 1-12% natural antibacterial agent, 0.5-8% environmentally friendly detergent builder or chelating agent, 0.1-4% thickener, 0-1% pH adjuster, 0-0.5% plant essential oil, 0-2% biological enzyme preparation, 0-5% solubilizer, and the balance being deionized water.

[0009] Furthermore, the surfactant includes at least one of alkyl glycosides, anionic surfactants, and nonionic surfactants.

[0010] Furthermore, the natural antibacterial agent includes at least one of cicada flower extract, tea saponin, artemisia extract, and honeysuckle extract.

[0011] Furthermore, the environmentally friendly detergent builder or chelating agent includes at least one of ethylenediamine disuccinate trisodium (EDDS), tetrasodium glutamate diacetate (GLDA), and N-alkylpropylaminoacetic acid.

[0012] Furthermore, it also contains 0.5% to 2% by weight of biological enzyme preparations.

[0013] Furthermore, it also contains 0.1% to 0.5% plant essential oils by weight.

[0014] A method for preparing the aforementioned environmentally friendly antibacterial laundry detergent includes the following steps:

[0015] (1) Under stirring conditions, the surfactant and cosolvent in the specified proportions are added to a portion of deionized water and stirred thoroughly until completely dissolved to obtain mixture A;

[0016] (2) In another container, add the environmentally friendly detergent or chelating agent and thickener in the specified proportion to the remaining deionized water, stir and disperse evenly to obtain mixture B;

[0017] (3) Slowly add mixture B to mixture A and stir continuously to make it evenly mixed;

[0018] (4) After the system stabilizes, add the natural antibacterial agent, biological enzyme preparation and plant essential oil in the specified proportion to the system, and adjust the pH value to neutral or weakly alkaline.

[0019] (5) Finally, add the remaining deionized water and continue stirring until the system is uniform and transparent to obtain the environmentally friendly antibacterial laundry detergent.

[0020] Furthermore, in step (4), a pH adjuster is used to adjust the pH of the system to 7.0 to 8.5.

[0021] The advantages of this invention compared to the prior art are:

[0022] 1. This invention selects cicada flower extract, tea saponin and other natural antibacterial agents to form a compound, which broadens the antibacterial spectrum and has excellent inhibitory effects on a variety of bacteria and fungi, while avoiding the environmental residue and drug resistance problems of chemical antibacterial agents.

[0023] 2. This invention achieves highly efficient removal of various stains such as protein, grease, and starch through the synergistic effect of environmentally friendly surfactants (such as alkyl glycosides) and biological enzyme preparations, with cleaning power comparable to traditional laundry detergents.

[0024] 3. The main components (surfactants, chelating agents, etc.) in the formulation of this invention are all environmentally friendly raw materials that are easily biodegradable, which greatly reduces the environmental impact on the aquatic ecosystem.

[0025] 4. The formula of this invention, which is dominated by natural ingredients, is less irritating to human skin and is safer to use. Its pH value is close to neutral or slightly alkaline, which minimizes damage to fabrics.

[0026] 5. Through optimized preparation process, this invention ensures that all components are fully dissolved and mixed, resulting in a stable, transparent, and uniform product system with a high retention rate of active ingredients. Detailed Implementation

[0027] In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Furthermore, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0028] The present invention will now be described in further detail with reference to the embodiments.
