Background
Like microorganisms, mites are ubiquitous in the human living environment and are not harmful to the health of human beings at all times. Mites are widely distributed in dark corners of rooms, carpets, mattresses, pillows, sofas, air conditioners, summer sleeping mats and the like, and symptoms such as rhinorrhea, cough, asthma and the like are easily caused when corpses, secretions, metabolites and the like of the mites are inhaled into respiratory tracts of people or contact with skin.
At present, the existing mite removing methods in the market are mainly divided into two physical methods and two chemical methods, wherein the physical methods are realized by using a mite removing instrument, an air purifier and other equipment; the method of frequent cleaning or sun exposure, etc., which has a certain effect, is time-consuming and labor-consuming and has poor effect. Such as: the air purifier is long in time consumption and power-consuming, and time and labor are wasted in cleaning or sun exposure; ultraviolet tube that removes mite appearance and use on the market is mostly 6 ~ 15W, and power is less, only needs to shine for a long time and just has the effect, though the beater that removes on the mite appearance has the higher frequency to pat, but the range is too little, is the mite that colludes the form to the claw, does not have very big mite effect that removes. The chemical method mainly achieves the effect of killing or repelling mites by using substances which are harmful to mites or have aversion to odor, but many chemical synthetic raw materials are used in the market, and bring certain harm to human health.
Based on the reasons, the invention discloses a plant antibacterial mite-killing agent with high-efficiency mite killing and antibacterial effects and a preparation method thereof.
Disclosure of Invention
The invention aims to provide a plant antibacterial mite-killing agent and a preparation method thereof, wherein the plant antibacterial mite-killing agent can achieve good antibacterial mite-killing effect in places such as air, bedding and the like by extracting natural active ingredients of plants, selecting special raw materials and adopting a simple preparation process and only adding a small amount of the plant antibacterial mite-killing agent into a product.
In order to achieve the purpose, the invention adopts the following technical scheme:
the preparation method of the plant antibacterial mite-killing agent is provided, and the plant antibacterial mite-killing agent is prepared by mixing ethanol, a surfactant, dichlorobenzyl alcohol, thymol, plant essential oil and propylene glycol, and completely dissolving the mixture;
the surfactant is composed of polyoxyethylene octyl phenol ether and ammonium lauryl sulfate, and the plant essential oil is composed of wintergreen essential oil, citronella essential oil, geranium essential oil and tea tree essential oil.
In the invention, the wintergreen, the citronella, the geranium and the tea tree contain natural active ingredients, which can destroy the structure of a pathogenic mycoderm, kill or inhibit certain germs and effectively kill or repel mites. Specifically, the main active ingredient of the wintergreen essential oil is methyl salicylate, which has fresh mint smell, is a common medicinal material recorded in pharmacopoeia and has the effects of killing and expelling insects, and researches on the wintergreen essential oil by the team find that the wintergreen essential oil has relatively remarkable acaricidal activity on mites. In addition, the wintergreen essential oil has good inhibition effect on common pathogenic bacteria such as escherichia coli, staphylococcus aureus, pseudomonas aeruginosa, aspergillus niger, mucor globosus, trichoderma, candida albicans and the like, and also has the effects of relieving muscle and joint pain, revivifying, increasing vitality and the like; the citronella essential oil contains unsaturated alcohol and aldehyde, wherein citral and citral are mainly contained, and is of citronella of Gramineae. The essential oil is recognized to have good insect expelling effect for a long time, and has good inhibition effect on staphylococcus aureus, salmonella, escherichia coli, aspergillus niger, penicillium citrinum, candida and other strains; the geranium essential oil is mainly rich in citronellol, citronellyl formate, citral, menthone, various trace mineral elements and the like, has strong comprehensive sweet taste, and has the effects of relieving pain, resisting bacteria, deodorizing, expelling parasites and the like. In addition, the compound has good inhibition effect on bacterial fungi such as escherichia coli, bacillus subtilis, saccharomycetes, trichoderma, candida albicans, aspergillus niger and the like; the main active ingredients of the tea tree essential oil are terpineol, lemon essential oil, eucalyptol, anisic element and the like, and researches prove that the tea tree essential oil has the effects of diminishing inflammation, sterilizing, expelling parasites and killing insects. It also has strong inhibiting effect on Staphylococcus aureus, pneumococcus, Pseudomonas aeruginosa, Penicillium citrinum, etc.
According to the invention, after the four plant essential oils, the propylene glycol, the polyoxyethylene octyl phenol ether, the ammonium lauryl sulfate, the ethanol, the thymol and the dichlorobenzyl alcohol are compounded, the synergistic effect can be realized, the integral bacteriostasis and mite removing effects of the plant antibacterial mite removing agent are enhanced, the stability of the plant antibacterial mite removing agent system can be improved, and the phenomena of precipitation and the like are prevented.
According to the invention, polyoxyethylene octyl phenol ether, ammonium lauryl sulfate and ethanol are added into propylene glycol to form a solubilization system, so that the four added plant essential oils (wintergreen essential oil, citronella essential oil, geranium essential oil and tea tree essential oil) and dichlorobenzyl alcohol can be completely dissolved, and the phenomena of precipitation and the like can not occur when the four plant essential oils are added into a product or water, and the stability of the plant antibacterial mite removing agent and the water solution thereof is ensured.
The plant essential oil has the effects of bacteriostasis and mite removal, and also has the effects of refreshing, relieving pain, relieving itching, removing odor, enhancing immunity and the like. In addition, dichlorobenzyl alcohol also has broad-spectrum antibacterial property and good insect expelling effect, but is slightly soluble in water, and the aqueous solution of dichlorobenzyl alcohol is easy to separate out; thymol is also derived from natural plant thyme, has poor water solubility, has inhibitory effect on Staphylococcus aureus and Escherichia coli, and has paralysis and killing effects on many insects. According to the invention, after the four plant essential oils, thymol, propylene glycol, polyoxyethylene octyl phenol ether, ammonium lauryl sulfate, ethanol and dichlorobenzyl alcohol are compounded, the synergistic effect can be achieved, the integral bacteriostasis and mite removing effects of the plant antibacterial mite removing agent are enhanced, the functions of the plant antibacterial mite removing agent are expanded, the stability of a plant antibacterial mite removing agent system and an aqueous solution thereof can be improved, and the phenomena of precipitation and the like are prevented.
The preparation method of the plant antibacterial acarid remover is simple to operate, low in cost and easy for industrial production.
Further, the preparation method of the plant antibacterial mite killing agent comprises the following steps:
s10, respectively crushing wintergreen, citronella, geranium and tea tree, then adding propylene glycol solution with the concentration of 40% according to the material-to-liquid ratio of 1 (10-15), respectively carrying out ultrasonic extraction, filtering after ultrasonic treatment, collecting filtrate, repeating the operation twice, combining the filtrates, and carrying out evaporation concentration on the filtrate under the reduced pressure condition to obtain wintergreen essential oil, citronella essential oil, geranium essential oil and tea tree essential oil;
s20, uniformly mixing the wintergreen essential oil, the citronella essential oil, the geranium essential oil and the tea tree essential oil to obtain plant essential oil, adding propylene glycol into the plant essential oil, then adding polyoxyethylene octyl phenol ether, ammonium lauryl sulfate, ethanol, thymol and dichlorobenzyl alcohol, heating and stirring until the mixture is completely dissolved to obtain the plant antibacterial mite removing agent.
Further, the mass ratio of the wintergreen essential oil to the citronella essential oil to the geranium essential oil to the tea tree essential oil is (1-20): (0.1-20), for example, 5:5:5:1, 5:13:8:0.1, 10:6:1:1, 8:8:5:1, 7:10:20:2, 10:5:0.1:6 or 20:20:10, and the like, and is not specifically listed. The ratio of the four plant essential oils is optimized, so that the mite removing effect of the plant antibacterial mite removing agent can reach the optimum, wherein the tea tree essential oil has heavier smell, the smell of the plant antibacterial mite removing agent can be influenced by excessive addition, and the overall mite removing performance is not improved much by excessive addition.
Further, the mass ratio of the polyoxyethylene octyl phenol ether, the ammonium lauryl sulfate, the ethanol, the thymol, the dichlorobenzyl alcohol, the plant essential oil and the propylene glycol is (10-30): (5-10): 1-5): (1-10), (1-40) and (50-80).
Wherein, the ratio of the material to the liquid is more than 1:15, which increases the production cost of the plant antibacterial miticide, the efficacy of the extracted plant extract is slightly weaker than that of the 1:15, the ratio of the material to the liquid is less than 1:8, which causes incomplete extraction of the plant, and the concentration of the extract is higher, which may cause the risk of flocculation and precipitation in the later period.
Further, the heating and stirring temperature is 25-50 ℃. Wherein, dichlorobenzyl alcohol, thymol and plant essential oil have poor solubility in propylene glycol or water, and the polyoxyethylene octylphenol ether, ammonium lauryl sulfate and ethanol are added to improve the solubility of the three raw materials and simultaneously improve the stability of the plant antibacterial miticide and the stability of the plant antibacterial miticide added in other products. The dissolving temperature is 25-50 ℃ to improve the dissolving rate of the raw materials in the propylene glycol, and the temperature is more than 50 ℃ to easily volatilize the ethanol and the propylene glycol and reduce the dissolving rate of the dichlorobenzyl alcohol.
Further, the ilex, the citronella, the geranium and the tea tree are crushed and then respectively sieved by a 50-mesh sieve, and the mesh number is too high, so that a large amount of plant raw materials are lost, and the plant active ingredients extracted later are less; and the wintergreen essential oil, the citronella essential oil, the geranium essential oil and the tea tree essential oil are 1/3-1/4 of the original volume respectively.
The term "original volume" refers to the volume of a plant after being crushed and sieved and added with 40% propylene glycol solution according to the feed-liquid ratio of 1: 15.
On the other hand, the invention also provides a plant antibacterial mite-killing agent which is prepared from the following raw materials in parts by weight:
the plant essential oil comprises wintergreen essential oil, citronella essential oil, geranium essential oil and tea tree essential oil, and the surfactant comprises polyoxyethylene octyl phenol ether and ammonium lauryl sulfate.
Further, the plant essential oil comprises, by weight, 1-20 parts of wintergreen essential oil, 1-20 parts of citronella essential oil, 0.1-20 parts of geranium essential oil and 0.1-20 parts of tea tree essential oil.
The plant antibacterial mite killing agent prepared by the preparation method is stable in system and high in mite killing efficiency.
According to the invention, the raw materials are optimized, so that the plant antibacterial mite-killing agent has a stable system, and has high-efficiency mite killing and bacteriostatic effects.
The plant antibacterial mite-killing agent is light yellow to red transparent liquid, and the pH value of the acid-base of the plant antibacterial mite-killing agent is 4.0-8.0. If the pH is less than 4.0 or more than 8.0, the vegetable antimicrobial miticide added to an aqueous solution or toilet water may cause precipitation, or lose-bearing property of the product.
Further, the surfactant is composed of 10-30 parts of polyoxyethylene octyl phenol ether and 5-10 parts of ammonium lauryl sulfate.
In still another aspect, the invention also provides a daily chemical product, which comprises the plant antibacterial acaricidal agent prepared by the preparation method.
The invention has the beneficial effects that: according to the invention, after the four plant essential oils, the propylene glycol, the polyoxyethylene octyl phenol ether, the ammonium lauryl sulfate, the ethanol, the thymol and the dichlorobenzyl alcohol are compounded, the synergistic effect can be achieved, the integral bacteriostasis and mite removing effects of the plant antibacterial mite removing agent are enhanced, the stability of the plant antibacterial mite removing agent system is improved, and the phenomena of precipitation and the like are prevented.

The plant antibacterial and mite-killing agents prepared in comparative example 3 and comparative example 4 were used for killing and repelling mites respectively at the addition levels of 1% and 2% by using the same methods and standards as described above, and the test results are shown in fig. 3 and fig. 4. As can be seen from fig. 3 and 4, when the test results of example 1 and comparative example 3 and comparative example 4 are compared, the mite control rate is 100%, 92% and 94% in sequence when the addition amount is 1%; when the addition amount is 2%, the mite-repelling rate is 99%, 85% and 90% in sequence. Therefore, in the preparation method of the plant antibacterial mite-killing agent, the mite-killing performance of the plant antibacterial mite-killing agent is reduced because dichlorobenzyl alcohol or thymol is not added.
In addition, the Minimum Inhibitory Concentration (MIC) of the plant antibacterial miticide prepared in example 1 and comparative examples 3 to 4 was determined by an agar dilution method, and the results are shown in Table 2.
TABLE 2 MIC (mg/L) values of the plant antibacterial mite-killing agent for part of the strains
As shown in Table 2, the plant antibacterial and acaricidal agent prepared in example 1 has excellent inhibitory effect on bacteria and fungi, and the absence of dichlorobenzyl alcohol or thymol in comparative examples 3 and 4 results in a reduction in the inhibitory effect on part of bacteria or mold.
Similarly, the plant antibacterial and mite-killing agents prepared in the embodiments 2 to 5 are respectively detected according to the above adding amount and the above detection method and standard, and the results substantially the same as those of the embodiment 1 are obtained, and detailed description is omitted.
The above examples are only intended to illustrate the detailed process of the present invention, and the present invention is not limited to the above detailed process, i.e., it is not intended that the present invention necessarily depends on the above detailed process for its implementation. It is understood by those skilled in the art that any modification of the present invention, equivalent substitutions of the raw materials of the product of the present invention and the addition of auxiliary components, selection of specific modes, etc., are within the scope and disclosure of the present invention.
