Description
Technical Field
The invention relates to the technical field of daily chemical products, in particular to a hand-washing-free disinfection gel containing natural green tea extract and a preparation method thereof.
Background
Among the various organs of the body, the hand is the site that is directly exposed and most exposed to the outside. In people's daily life and work, especially in some special places such as hospitals, stations, movie theaters and internet cafes, the hands of people inevitably come into contact with some bacteria and virus microorganisms, even pathogenic microorganisms. Since these microorganisms not only cause self-infection but also cross-infection, direct disinfection of the hands in order to kill these pathogenic bacteria and viruses in a budding state is one of the most effective, simple and easy measures.
The hand disinfection products on the market are very various, wherein the hand-washing-free gel type disinfectant is used as a new cleaning mode, has the advantages of easiness in storage and difficulty in splashing and dripping, and mainly has the characteristic of hand washing free.
The hand-washing-free disinfection gel mainly comprises three parts, including a gel thickener, disinfection components and auxiliary additives, wherein the gel thickener has the function of enabling the whole system to be in a viscous state between solid and liquid, and is mostly cellulose and carbomer; the disinfectant component is effective component of disinfectant, and is some medicines with effects of sterilizing, disinfecting, and inhibiting microorganism propagation, such as long-acting or short-acting disinfectant including ethanol, isopropanol, triclosan, phenols, guanidine, etc.; the auxiliary additives include pH buffers, fragrances, and the like to enhance the comfort of use of the disinfectant. However, the addition of disinfectants such as 2,4,4' -trichloro-2-hydroxy-diphenyl ether, triclosan, polyhexamethylene guanidine, and other chemical raw materials directly or indirectly irritates the skin and causes certain side effects.
According to related researches, the main active ingredient of the extract in the green tea is tea polyphenol, and epigallocatechin, gallate and epicatechin gallate contained in the extract have good bacteriostatic ability, so that the extract is widely used as an antibacterial drug with high efficiency and low toxicity and is well accepted by scholars in many countries in the world. Therefore, the natural tea extract containing tea polyphenol can also be used as a disinfectant component to be added into the disinfectant gel. More than this, tea polyphenol also has the ability of anti-oxidation and anti-ultraviolet, can improve the efficacy of whitening and anti-wrinkle when added into daily chemical products, and can also be used as an excellent auxiliary additive in disinfection gel due to aromatic and pleasant smell.
Disclosure of Invention
Aiming at the problems of the prior art, the invention aims to provide a hand-washing-free disinfection gel containing natural green tea extract and a preparation method thereof. The natural green tea extract-containing no-clean hand disinfection gel takes green tea as a main raw material, ethanol water solution is introduced as an excellent extraction solvent of tea raw materials, then a thickening agent with a certain proportion is added into the extract solution, and the natural green, sterilization and disinfection gel containing the natural green tea extract, which is convenient to use, can be prepared after uniform mixing.
The present invention adopts the following technical means to achieve the above object.
The preparation method of the hand-washing-free disinfection gel containing the natural green tea extract comprises the following steps: (1) and (3) tea treatment: adding folium Camelliae sinensis 100oDrying for 12h in an oven to constant weight, crushing by a crusher, sieving by a 30-mesh sieve to obtain green tea powder, sealing, drying and storing for later use, (2) weighing a certain amount of thickener powder, stirring and mixing with a corresponding volume of deionized water, standing for 24h to obtain a transparent thickener colloid for later use, (3) mixing a certain amount of tea powder with a corresponding volume of ethanol aqueous solution, extracting for a period of time by an ultrasonic extraction method, (4) rapidly performing suction filtration on suspension after ultrasonic treatment, recovering filtrate, adding the thickener colloid in proportion, and (5) finally stirring the mixed solution by a magnetic stirrer for 6 ~ 8h to form uniform and stable viscous colloid, namely the hand-washing-free disinfection gel containing the natural green tea extract is successfully prepared.
The tea leaves in the step (1) are fresh green tea leaves.
The thickener powder in the step (2) is a carbomer thickener, preferably carbomer 941.
The ratio of the thickener powder to the deionized water in the step (2) is 2g/100 mL.
The concentration of the ethanol aqueous solution in the step (3) is 75%.
The mixing ratio of the tea powder and the ethanol aqueous solution in the step (3) is 5g/100 mL.
The preferable ultrasonic extraction conditions in the step (3) are as follows: power 350w, temperature 60oC. The action time is 30 min.
The preferable volume ratio of the thickener colloid to the extracting solution in the step (4) is 5: 16.
The invention has the beneficial effects that: the hand-washing-free disinfection gel containing the natural green tea extract fully utilizes tea polyphenol substances with antibacterial and bacteriostatic properties in tea leaves, improves the long-acting bacteriostatic ability of the disinfection gel, is aromatic and pleasant, is environment-friendly and has no stimulation, and hands are cared. Meanwhile, the method directly extracts from the green tea, can expand the functions of the green tea, enables the green tea with poor quality to be utilized, and is a derivative product and a process of the green tea.
Detailed Description
