Description

Technical Field

[0001] The invention belongs to the technical field of deodorants, and in particular relates to a composite plant deodorant and a preparation method thereof. Background Art

[0002] With the rapid development of modern industry and the improvement of people's living standards, the problem of odor pollution has become increasingly prominent and has become an important concern in the field of environmental governance. Malodorous gases not only seriously affect the quality of life of surrounding residents, but may also cause many adverse effects on human health, such as causing respiratory diseases, irritating eyes and skin, etc. Traditional deodorization methods include physical adsorption and chemical oxidation. Although physical adsorption methods such as activated carbon adsorption can adsorb odor molecules to a certain extent, the adsorption capacity is limited and easy to saturate, and the subsequent treatment cost is high. Chemical oxidation methods such as using strong oxidants to treat odors have high oxidation efficiency, but there are problems such as harsh reaction conditions and possible secondary pollution. In recent years, plant extracts have been increasingly concerned in the field of deodorants due to their natural, renewable and environmentally friendly characteristics. Although a variety of single plant extracts have been used in deodorization research, this type of deodorant often has the problem of insufficient odor suppression effect and weak antibacterial performance, and it is difficult to effectively prevent the re-generation of malodorous gases caused by microbial growth.

[0003] Therefore, it is of great practical significance to provide a deodorant with excellent odor-inhibiting and antibacterial properties. Summary of the invention

[0004] The object of the present invention is to provide a composite plant deodorant and a preparation method thereof, which solves the problem that the deodorants in the prior art have poor odor and antibacterial properties.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A composite plant deodorant, comprising the following raw materials in parts by weight:

[0007]

[0008]

[0009] Fulvic acid is composed of molecular clusters with similar properties, and has good water solubility, high chemical activity and strong chelation effect. The silver ions in silver nitrate can penetrate the bacterial cell wall and destroy the activity of bacterial synthase, thereby causing the bacteria to lose the ability to divide and proliferate. The copper ions in copper sulfate can interact with the bacterial cell membrane and destroy the bacterial structure and kill the bacteria.

[0010] Furthermore, the Alpinia galanga extract is obtained by extracting the Alpinia galanga root using water as a solvent through a room temperature immersion method; the Geranium sibiricum extract is obtained by extracting the whole herb of Geranium sibiricum using alcohol as a solvent through a room temperature immersion method.

[0011] As a preferred technical solution of the present invention, the deodorant also includes deionized water.

[0012] As a preferred technical solution of the present invention, the deodorant further comprises 13-21 parts by weight of black plum extract and 13-18 parts by weight of tataric acid bean extract.

[0013] Furthermore, the black plum extract is obtained by extracting the black plum fruit with water as a solvent through a room temperature immersion method; the tamarind extract is obtained by extracting the dried tamarind fruit with warm water as a solvent through a room temperature immersion method.

[0014] As a preferred technical solution of the present invention, the deodorant also includes 1-2 parts by weight of 108 mmol / L zinc gluconate solution.

[0015] A method for preparing a composite plant deodorant specifically comprises the following steps:

[0016] S1, stirring fulvic acid, silver nitrate, copper sulfate and deionized water in a temperature-controlled water bath to obtain a mixed solution A, placing the mixed solution A in a reaction kettle with temperature-controlled stirring, cooling, freeze-drying, and temperature-controlled nitrogen carbonization to obtain a complex;

[0017] S2. Mix the extracts evenly and add deionized water once, control the temperature and stir once, centrifuge at a controlled speed, take the supernatant after centrifugation, add deionized water again, control the temperature and stir again, add the complex and the remaining raw materials, stir evenly at a constant temperature, let stand to room temperature, and can the finished product to obtain a finished deodorant.

[0018] As a preferred technical solution of the present invention, the weight of the deionized water added in step S1 is 25-28 times the total weight of fulvic acid, silver nitrate and copper sulfate.

[0019] As a preferred technical solution of the present invention, the temperature of the temperature-controlled water bath stirring in step S1 is 35-40°C, and the time is 6-8h; the temperature of the temperature-controlled stirring in the reactor is 120-125°C, and the time is 1.5-2h; the cooling is cooling to room temperature; the freeze-drying time is 48-52h; the temperature of the temperature-controlled nitrogen carbonization is 300-320°C.

[0020] As a preferred technical solution of the present invention, the weight of deionized water added once in step S2 is 4-5 times the total weight of the extract; the weight of deionized water added twice is 3-4 times the total weight of the supernatant after centrifugation.

[0021] As a preferred technical solution of the present invention, the temperature of the first temperature-controlled stirring in step S2 is 35-45°C, and the time is 20-30min; the speed of the speed-controlled centrifugation is 3500-4000rpm, and the time is 20-30min; the temperature of the second temperature-controlled stirring is 45-50°C; the temperature of the constant temperature stirring is 45-50°C, and the time is 30-40min.

[0022] Beneficial effects of the present invention:

[0023] (1) The present invention adds an Alpinia officinalis extract rich in flavonoids such as galangin, kaempferol and isorhamnetin, and adds a Geranium herb extract rich in tannin active ingredients such as geranin, ellagic acid and chebulic acid, so that the flavonoids and tannin active ingredients therein can effectively fix the odor molecules to a certain extent through complexation. At the same time, on this basis, the Alpinia officinalis extract rich in organic acids such as citric acid, oxalic acid and malic acid and the Tamarind extract rich in organic acids such as tartaric acid and oxalic acid are added, so that the organic acids therein interact with the tannin active ingredients, thereby further enhancing the ability of the system to fix the odor molecules. Therefore, the Alpinia officinalis extract, Geranium herb extract, Eume extract and Tamarind extract added to the raw materials of the present invention can synergistically make the prepared deodorant have excellent odor suppression effect.

[0024] (2) The present invention complexes fulvic acid with silver nitrate and copper sulfate, and the silver ions and copper ions therein provide bactericidal properties. Zinc gluconate is also added to provide zinc ions that combine with bacterial cell membranes and membrane proteins to destroy the bacterial structure, thereby further assisting the complex in the system to jointly exert a bactericidal effect. In this way, the deodorant product prepared thereby has excellent antibacterial properties.

[0025] (3) The present invention also adds tridecyl alcohol polyether-6 to enhance the chelating and capturing ability of metal ions in the system for malodorous gases, and adds lauryl alcohol polyoxyethylene ether to help stabilize the dispersion of the system components; therefore, tridecyl alcohol polyether-6 and lauryl alcohol polyoxyethylene ether can synergistically assist in enhancing the odor suppression and bactericidal ability of the finished deodorant, so that the prepared deodorant can effectively prevent the re-diffusion of malodorous gases from the two aspects of odor suppression and bactericidal, thereby fundamentally achieving the purpose of deodorization.
