Obviously, for those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0024] Figure 1 It is a schematic flow chart of a preparation method of a natural, environmentally friendly and antibacterial laundry detergent provided by an embodiment of the present application. Specific embodiments

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0026] Unless otherwise specifically stated, various raw materials, reagents, instruments and equipment used in the present application can be obtained through market purchases or can be prepared by existing methods.

[0027] In a first aspect, the present application provides a natural, environmentally friendly and antibacterial laundry detergent. By weight, the natural, environmentally friendly and antibacterial laundry detergent includes the following components:

[0028] 5 - 12 parts of cicada flower extract, 10 - 40 parts of alkyl polyglycoside, 1 - 5 parts of N - alkyl propylamino glycine, 0.5 - 5 parts of complexing agent, 0.1 - 4 parts of thickening agent and 100 parts of water.

[0029] The functions of the main components in the natural, environmentally friendly and antibacterial laundry detergent provided by the embodiments of the present application are as follows:

[0030] Cicada flower extract: Rich in active ingredients such as cicada flower polysaccharide, it has functions such as antibacterial and insecticidal effects; at the same time, it can jointly form an extracellular colloidal matrix rich in moisture with the polysaccharide components and fibrous proteins in the skin, which can provide moisture for the skin and has no irritation to the human skin.

[0031] Alkyl polyglycoside (abbreviated as APG): A new type of non - ionic surfactant with relatively comprehensive properties, combining the characteristics of ordinary non - ionic and anionic surfactants, having high surface activity, good ecological safety and compatibility, and is the internationally recognized preferred "green" functional surfactant.

[0032] N-alkylpropylaminoacetic acid: an amphoteric amino acid-based surfactant, which is the only amphoteric surfactant disinfectant registered in the EU. It does not contain aldehydes or active chlorine components, is mild, easily degradable, environmentally friendly and safe, and also has a powerful cleaning promotion and solubilization effect.

[0033] Therefore, the applicant first used cicada flower extract as the main disinfection and antibacterial component of the laundry detergent, alkyl polyglycoside as the main washing and decontamination component, and N-alkylpropylaminoacetic acid as the antibacterial and decontamination enhancing component. The three components synergistically cooperate with each other to obtain a natural environmental protection antibacterial laundry detergent with the characteristics of green environmental protection, safety and mildness, and strong decontamination ability, further improving the safety, environmental protection and decontamination ability of the existing antibacterial laundry detergent.

[0034] As an implementation manner of the embodiment of the present application, the weight ratio of the cicada flower extract, the alkyl polyglycoside and the N-alkylpropylaminoacetic acid is 17:45:5.

[0035] The applicant found through research that when the weight ratio of the cicada flower extract, the alkyl polyglycoside and the N-alkylpropylaminoacetic acid is controlled to be 17:45:5, the synergistic effect of the cicada flower extract, the alkyl polyglycoside and the N-alkylpropylaminoacetic acid is better, and the antibacterial effect and decontamination ability of the laundry detergent can be significantly improved.

[0038] As an implementation manner of the embodiment of the present application, the cicada flower extract is a cicada flower fruiting body extract.

[0039] Using the cicada flower fruiting body extract as the main disinfection and antibacterial component of the laundry detergent has a good antibacterial effect. In some specific embodiments, in terms of weight percentage, the content of polysaccharide in the cicada flower extract is 50wt%, such as the commercially available cicada flower extract (manufacturer: Fufeng Sinuote Biotechnology Co., Ltd., product model SNT1106) can be used.

[0040] As an implementation manner of the embodiment of the present application, the complexing agent is at least one of tetrasodium glutamate diacetate and L-560 organic complexing agent.

[0041] The present application selects tetrasodium glutamate diacetate and L-560 organic complexing agent, which is beneficial to the stability of the whole system, has good compatibility with the cicada flower extract, and is beneficial to the storage of the product.

[0042] As an implementation manner of the embodiment of the present application, the thickener is at least one of polyethylene glycol 6000 distearate, sodium chloride, and coconut oil fatty acid diethanolamide.

[0043] The present application selects polyethylene glycol 6000 distearate, sodium chloride, and coconut oil fatty acid diethanolamide to increase the viscosity of the system.

[0044] As an implementation manner of the embodiment of the present application, the alkyl polyglycoside is at least one of APG0810, APG0814, and APG1214.

[0045] The present application first selects commercially available APG0810, APG0814, and APG1214 as the disinfection and antibacterial components of the laundry detergent, replacing the existing ones such as silver ions, hydrogen peroxide, trichlorohydroxy dipropyl ether, and dodecyl dimethyl benzyl ammonium chloride, effectively avoiding the impact of existing antibacterial laundry detergents on aquatic organisms such as algae, and providing a new idea for the preparation of antibacterial laundry detergents.

[0046] In a second aspect, based on a general inventive concept, the present application provides a preparation method for the natural and environmentally friendly antibacterial laundry detergent according to any one of the first aspects, as Figure 1 shown, the preparation method includes:

[0047] Under the condition of continuous stirring, add cordyceps sinensis extract, alkyl polyglycoside, and N-alkyl propylamino acetic acid to water in sequence to obtain a first mixture;

[0048] Add a complexing agent and a thickener to the first mixture and perform ultrasonic mixing and stirring to obtain the natural and environmentally friendly antibacterial laundry detergent.

[0049] The preparation method for the natural and environmentally friendly antibacterial laundry detergent provided by the present application is simple in operation, does not require additional specific equipment, and is suitable for industrial production. At the same time, the preparation method for the natural and environmentally friendly antibacterial laundry detergent is realized based on the natural and environmentally friendly antibacterial laundry detergent according to any one of the first aspects. Therefore, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated here one by one.
