Description

Technology Field

[0001] The present invention relates to a biodegradable film-type disinfectant and a disinfection product containing the same. Background Technology

[0002] Microorganisms are living organisms that are always present in our surroundings. While there are beneficial microorganisms that help humans, there are also harmful ones, such as pathogenic microorganisms and putrefactive bacteria, that cause problems including disease, foul odors, and aesthetic repulsion. These harmful microorganisms can exist on the surfaces of the body, including hair, the body, hands, and feet, and can contaminate the surfaces of foods such as vegetables, fruits, and fish, as well as cooking utensils, tableware, cooking areas, and restrooms—objects closely related to daily life.

[0003] As such, there is a need for antimicrobial cleaning agents to sterilize and clean microorganisms contaminating surfaces such as tableware and the body in order to maintain a safe and hygienic life free from harmful microorganisms that can threaten human life; accordingly, various antimicrobial cleaning agents are being developed. However, most of the cleaning agents used so far have been manufactured through chemical synthesis, and bleach-type chlorine-based disinfectants are representative of commonly used antimicrobial cleaning agents. Although bleach exhibits strong antimicrobial activity due to nascent oxygen generated from hypochlorous acid (HCl), bleach-based cleaning agents are harmful to the skin due to their high alkalinity, and concerns regarding human safety have been reported due to the toxicity generated during use. Furthermore, due to the emergence of bacteria resistant to existing chemically synthesized antimicrobial agents and cleaning agents, as well as side effects caused by toxicity affecting the human body, there has recently been a growing interest in antimicrobial cleaning products that are eco-friendly and safe for residential environments and humans. Accordingly, there is a demand for the development of antimicrobial cleaning agents that utilize natural substances found in nature instead of chemical substances harmful to health.

[0004] As a result of these efforts, Korean Patent No. 1451730 discloses an antibacterial cleaning composition containing various plant extracts, such as Phellodendron amurense extract, and Korean Registered Patent No. 1626048 discloses an antibacterial cleaning composition containing a mixture of green tea catechin, rosemary oil (Rosmarinus officinalis Leaf Oil), and lavender oil (Lavandula angustifolia Oil) as active ingredients.

[0005] However, in the case of eco-friendly cleaning compositions containing natural ingredients as active ingredients, such as the aforementioned prior art, they combine plant extracts with antibacterial activity with surfactant components; they retain the limitations of existing cleaning compositions in that manufacturing costs increase depending on the supply conditions of raw materials or because surfactant components are ultimately used.

[0006] Oxidizing biocides exert a bactericidal effect by oxidizing the cellular proteins of microorganisms through their strong oxidizing power. Chlorine (or a combination of chlorine and bromine) and monochloramine are primarily used. Chlorine and bromine are strong oxidizing agents (acutely toxic) with short half-lives, but they form halogenated byproducts upon contact with halogenated substances. Other oxidizing biocides include ozone, ultraviolet light, hydrogen peroxide, and peracetic acid. Ozone and ultraviolet light require pretreatment of replenished water or additives; while they are less harmful than halogenated biocides, their high cost is a disadvantage, preventing their application in all situations.

[0007] Chlorine disinfectants most commonly used as cooling water disinfectants include chlorine gas, calcium hypochlorite, and sodium hypochlorite. Although there are differences in form, there is no significant difference in the mechanism of action of these chlorine disinfectants.

[0008] Recently, disinfectants containing natural or eco-friendly ingredients are being developed to address these issues, with biodegradable disinfectants receiving particular attention. While biodegradable disinfectants have the advantage of easily decomposing in the natural environment to minimize environmental impact, existing models have limitations in maintaining effective disinfection power. Furthermore, it is often difficult to control the continuous release of disinfectant components after use.

[0009] Temperature-sensitive polymers are materials that exhibit changes in physical and chemical properties in response to specific temperature changes, and are primarily utilized in temperature-sensitive drug delivery systems or smart materials. Temperature-sensitive polymers are mainly materials such as PNIPAAm (poly-N-isopropylacrylamide), which possess the property of changing their water solubility or insolubility depending on temperature variations. When such polymer materials are applied to disinfectants, disinfectant components are automatically released or activated according to body temperature or external temperature, thereby providing efficient disinfection.

[0010] However, the development of biodegradable polymers has been a significant technical challenge in applying temperature-sensitive polymers to disinfectants. Conventional temperature-sensitive polymers are generally non-biodegradable, posing a problem in that they do not decompose in nature or their environmental impact can increase over time. Therefore, temperature-sensitive biodegradable disinfectants are attracting attention as an innovative technology that maintains disinfection efficacy while possessing eco-friendly characteristics.

Specific details for implementing the invention

[0026] Prior to the description of the present invention, the definitions of each term are as follows.

[0027] The term "extract" in this specification follows the dictionary definition and may refer to a liquid substance drawn from a specific substance or state.

[0028] The term "concentrate" in this specification follows the dictionary definition and may refer to a liquid substance in which the content of water or solvent has been reduced through evaporation or other processing, and may be used interchangeably with "essence."

[0029] The term "extract" in this specification follows the dictionary definition and refers to a substance obtained by concentrating a specific component in an extract, wherein a specific active component is separated using a suitable solvent, and the solvent is completely or mostly evaporated to obtain a remaining mass or powder which is then adjusted according to standards. In this specification, the term "extract" may be used to include all three forms: semi-fluid or syrup-like, pill-like or solid, dried powder, etc.

[0030] The term "extract" in this specification follows the dictionary definition and may refer to a solution in which the concentration has been reduced in liquid form, including an extract or concentrate of a specific component.

[0031] A fragrance accord in this specification refers to a mixture of fragrance ingredients. As used herein, the term “perfuming ingredient” refers to a compound used for the primary purpose of imparting or modifying a fragrance. In other words, for such an ingredient to be considered a fragrance ingredient, it must be recognized by a person skilled in the art not only as having a fragrance, but also as being capable of conveying or altering the fragrance of a composition in a positive or pleasant way. For the purposes of the present disclosure, perfume accords include combinations of perfume ingredients and substances that improve, enhance, or adjust the delivery of perfume ingredients when used together, such as perfume precursors, emulsions, or dispersions, as well as combinations that can provide additional benefits beyond delivering or altering the scent, such as long-lasting, blooming, malodour counteraction, antimicrobial effect, microbial stability, and insect control.

[0032] The properties and types of fragrance ingredients are not to be described in more detail in the present invention and will not be comprehensive in any case, and those skilled in the art may select them based on their general knowledge and according to the intended use or application and the desired organoleptic effect. Generally, these fragrance ingredients belong to various chemical classes such as alcohols, aldehydes, ketones, esters, ethers, acetates, nitriles, terpenoids, nitrogenous or sulfurous heterocyclic compounds, and essential oils, and said fragrance co-ingredients may be of natural or synthetic origin.

[0033] Most of these auxiliary components are listed in many patent literature in the field of fragrances, as well as in references such as S. Arctander, Perfume and Flavor Chemicals, 1969, Montclair, New Jersey, USA, or his more recent publications or other similar works. Additionally, it is understood that the above components may be compounds known to release various types of fragrance compounds in a controlled manner.

[0034] In one embodiment of the present application, the term “effective extract” may refer to a component or extract that exhibits a specific effect among the components included in the composition.

[0035] In one embodiment of the present application, "fragrance" refers to a material that enhances the favorability of a product or the utility of a product by providing a scent beneficial to humans to feel a sense of coolness, freshness, etc., or by providing functional properties beneficial to humans, such as a calming effect on the mind and body.

[0036] One embodiment of the present specification is a biodegradable film-type disinfectant comprising: a temperature-sensitive polymer comprising poly-N-isopropylacrylamide and polycaprolactam (PCL); and a disinfectant composition contained in the temperature-sensitive polymer; wherein the disinfectant composition comprises an antimicrobial substance comprising a hypochlorous acid disinfectant water having a pH of 4.5 to 6.5 and a hypochlorous acid (HOCl) content of 100 ppm to 600 ppm and peppermint oil; a fragrance extract; and an organic solvent; wherein the fragrance extract comprises a ginkgo extract, a thyme extract, and an aloe vera extract, and wherein, based on 100 parts by weight of the fragrance extract, the ginkgo extract comprises 30 parts by weight; and the thyme extract comprises 60 parts by weight.

[0037] The PNIPAAm used in this application changes its physical properties at a specific temperature called the LCST (Lower Critical Solution Temperature) (usually about 32°C), and generally has the characteristic of switching from water-soluble to insoluble at a temperature similar to body temperature.

[0038] In this case, the present application is designed to decompose in the natural environment by using a mixture of poly-N-isopropylacrylamide and polycaprolactam (PCL). It is characterized by the fact that the polymer itself can naturally decompose by blending the polymers together or by imparting the properties of a polyester. Although PNIPAAm itself is not biodegradable, it is biodegradable by combining it with a biodegradable polymer or chemically modifying it. By adding biodegradable properties, it can be developed into an environmentally friendly technology, which has been applied to a disinfectant film.

[0039] In other words, the film-type disinfectant according to the present application is a film-type disinfectant, unlike conventional liquid or gel types, and is easy to carry compared to liquid or gel types, allowing it to be used without restrictions at any desired location or time. Additionally, by using a temperature-sensitive polymer, it melts upon friction or temperature increase to release the disinfectant composition, thereby ensuring ease of use.

[0040] The temperature-sensitive polymer according to the present application comprises poly-N-isopropylacrylamide and polycaprolactam (PCL).

[0041] The present application provides a biodegradable film-type disinfectant in which the polycaprolactam is 10 parts by weight or less based on 100 parts by weight of the temperature-sensitive polymer.

[0042] In another embodiment, based on 100 parts by weight of the temperature-sensitive polymer, the polycaprolactam may comprise 10 parts by weight or less, specifically 5 parts by weight or more, and more specifically 10 parts by weight.

[0043] In the present application, the weight ratio of poly-N-isopropylacrylamide and polycaprolactam (PCL) in the temperature-sensitive polymer may be 9:1.

[0044] The temperature-sensitive polymer according to the present application is used as a film containing a disinfectant composition. When stored, it can be conveniently carried in the form of the film, and when used, the temperature-sensitive polymer decomposes due to increased temperature or friction, at which time the disinfectant composition is applied.

[0045] In the case of the temperature-sensitive polymer according to the present application, it has the weight ratio as described above, and by having the above range, the disinfectant composition can be easily applied when the temperature rises, and it also has biodegradability and thus possesses eco-friendly characteristics.

[0046] In the present application, the biodegradable film-type disinfectant is characterized by comprising a disinfectant composition in the temperature-sensitive polymer. Accordingly, when used, the temperature-sensitive polymer decomposes due to friction or increased temperature, and at this time, the disinfectant composition is applied, allowing it to be used on the skin or a desired location.

[0047] In the present application, the disinfectant composition comprises an antimicrobial substance comprising a hypochlorous acid disinfectant water having a pH of 4.5 to 6.5 and a hypochlorous acid (HOCl) content of 100 ppm to 600 ppm and peppermint oil; a fragrance extract; and an organic solvent.

[0048] The hypochlorous acid disinfectant water included in the disinfectant composition of the present invention is an aqueous solution obtained by electrolyzing hydrochloric acid in a membrane-free electrolytic cell composed of an anode and a cathode that are not separated by a membrane, and is a disinfectant water having a hypochlorous acid (HOCl) content of 100 ppm to 600 ppm.

[0049] In one embodiment of the present application, the hypochlorous acid (HOCl) content may be 100 ppm to 600 ppm, preferably 200 ppm to 600 ppm, and more preferably 400 ppm to 550 ppm.

[0050] If the amount of hypochlorous acid in the disinfectant of the present invention is 100 ppm or less, the lack of bactericidal power is the biggest problem, making it difficult to expect an effect of killing initial microorganisms or bacteria, and if it is 600 ppm or more, a very strong peculiar odor may occur, and due to excessive bleaching action, the surface of the object to be sterilized / disinfected may be discolored or the appearance may be altered.

[0051] In particular, the disinfectant composition according to the present application is characterized by including a small amount of hypochlorous acid disinfectant water and a natural substance, peppermint oil, in order to maximize the sterilization and antibacterial effects by using hypochlorous acid disinfectant water with a pH of 4.5 to 6.5 and a hypochlorous acid (HOCl) content of 100 ppm to 600 ppm as described above, while simultaneously suppressing the occurrence of a very strong specific odor, which is a problem of the past.

[0052] The peppermint oil according to the present application is prepared by converting naturally occurring peppermint into an oil form. Since it contains the antibacterial and sterilizing properties of peppermint itself along with a fragrance capable of eliminating peculiar odors, the antibacterial properties of the antibacterial substance contained in the disinfectant composition according to the present application are maintained, while simultaneously having the characteristic of eliminating peculiar odors.

[0053] In one embodiment of the present application, the antimicrobial substance may comprise 40 parts by weight or more and 60 parts by weight or less based on 100 parts by weight of the disinfectant composition.

[0057] In another embodiment, the peppermint oil may comprise 70 parts by weight or more and 90 parts by weight or less, 70 parts by weight or more and 85 parts by weight or less, more preferably 70 parts by weight or more and 80 parts by weight or less.

[0058] In the present application, the weight ratio of hypochlorous acid disinfectant water to peppermint oil, in which the hypochlorous acid (HOCl) content in the antimicrobial substance is 100 ppm to 600 ppm, may be 3:7.

[0059] The disinfectant composition according to the present application comprises hypochlorous acid disinfectant water and peppermint oil in the respective amounts as described above. Since it includes a fragrance capable of eliminating specific odors along with antibacterial and sterilizing properties, the antibacterial properties of the antibacterial substance itself included in the disinfectant composition according to the present application are maintained, while simultaneously having the characteristic of eliminating specific odors.

[0060] In the present application, the fragrance extract comprises a ginkgo extract, a thyme extract, and an aloe vera extract, wherein, based on 100 parts by weight of the fragrance extract, the ginkgo extract comprises 30 parts by weight; the thyme extract comprises 60 parts by weight; and the aloe vera extract comprises 10 parts by weight.

It is preferable to perform reflux extraction while heating or extraction at room temperature, but is not limited thereto.

[0062] For example, it may be a method prepared by a known method using ultrasonic extraction, reflux extraction, hot water extraction, or an extraction solvent, and preferably, it may be a reflux extraction method. In addition, these may be performed alone or in combination with two or more methods.

[0063] In one embodiment of the present application, the concentration of the ginkgo extract in the ginkgo extract may be 60%.

[0064] The above thyme extract contains thyme extract, which is a substance extracted from a plant called thyme. It is widely used in the pharmaceutical and cosmetic industries due to its various antibacterial, antiviral, and anti-inflammatory effects. Thyme is primarily a plant with the scientific name Thymus vulgaris, belonging to the Apiaceae family. Thyme extract can be obtained in the form of thyme essential oil or a water-soluble extract. This extract possesses various pharmacological properties and can be usefully utilized for health management and hygiene.

[0065] In this application, the aloe vera extract is a substance extracted from the Aloe vera (scientific name: Aloe vera) plant, which is widely used due to its various health and beauty benefits. Aloe vera is a plant with a high water content containing various nutrients such as vitamins, minerals, and enzymes, providing skin soothing, anti-inflammatory, antibacterial, and antioxidant properties. It is primarily used for skin care and improving digestive health, and is utilized as an important raw material in cosmetics, pharmaceuticals, and health supplements.

[0066] In the present application, the fragrance extract may comprise at least 10 parts by weight and no more than 30 parts by weight based on 100 parts by weight of the disinfectant composition.

The following examples and experimental examples are provided to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention.

[0090] <Preparation Example>

[0091] <Example 1>

[0092] A temperature-sensitive polymer was prepared by mixing 90 parts by weight of poly-N-isopropylacrylamide and 10 parts by weight of polycaprolactam (PCL). Subsequently, a disinfectant composition was applied to the temperature-sensitive polymer, and then compressed and stretched into a film form to produce a biodegradable film-type disinfectant.

[0093] At this time, the composition included in the disinfectant composition was as follows.

[0094] - Preparation of fragrance extract

[0095] [Preparation Example 1-1] - Preparation of Ginkgo Extract

[0096] The ginkgo leaves used in this experiment were collected from Pyeongchang, Gangwon-do. 100 g of ginkgo leaves were mixed with 2.7 L of 50% ethanol and extracted at 60 ℃ for 3 hours using a water bath (Dongseo Science DS-SWB-4). The filtrate was then filtered under reduced pressure using filter paper, and a concentrated solution was obtained using a vacuum rotary evaporator (BUCHI Rotavapor R-144, Switzerland). This was then dried using a freeze dryer to obtain 100% ginkgo leaf powder.

[0097] Subsequently, ginkgo leaf powder was mixed with edible purified water, and the concentration of ginkgo extract in the final ginkgo extract was confirmed to be approximately 60%.

[0098] [Preparation Example 1-2] - Preparation of thyme extract

[0099] Thyme produced in Wonju-gun, Gangwon-do is purchased, the stems are removed, and only the thyme leaves are washed with purified water, air-dried, and manufactured through a generally known extraction process. The air-dried thyme leaves are taken, ground into powder form, and extracted at 250 RPM using an agitator (AGI agitator, PLHP 400HS Poong Lim. Co). To facilitate long-term storage of the concentrated thyme leaf extract and easy mixing into the final composition, it is rapidly frozen using an ultra-low temperature freezer (Deep Freezer, ILSHIN Lab Co., Ltd) and dried at a temperature of -60℃ under a vacuum of 1.5 Torr using a freeze dryer (Freez dryer, ILSHIN Lab Co., Ltd). The yield of the freeze-dried thyme extract is 1.8% relative to the raw material.

[0100] Afterwards, thyme extract was mixed with edible purified water, and the concentration of thyme extract in the final extract was confirmed to be about 50%.

[0101] [Preparation Example 1-3] Aloe Vera Extract

[0102] The aloe vera extract was purchased from an auction and used, and the concentration of aloe vera extract in the final extract was confirmed to be approximately 50%.

[0103] Subsequently, a fragrance extract was prepared as shown in Table 1 below.

[0105] An organic solvent was prepared in a triangular flask containing 6 parts by weight of acetone, 4 parts by weight of ethyl acetate, and 90 parts by weight of propylene glycol monomethyl ether, based on 100 parts by weight of the total organic solvent.

[0106] After this Peppermint oil from LIMS Aroma was used. Hypochlorous acid disinfectant water with a hypochlorous acid (HOCl) content of 500 ppm and a pH of 5 to 6 was prepared.

[0107] An antimicrobial substance was prepared by mixing 70 parts by weight of the peppermint oil and 30 parts by weight of the hypochlorous acid disinfectant water based on 100 parts by weight of the antimicrobial substance in an Erlenmeyer flask, and a disinfectant composition was prepared by mixing the antimicrobial substance prepared above, the fragrance extract, and the organic solvent in the respective ratios shown in Table 2 below. The parts by weight in Table 2 below are listed based on 100 parts by weight of the total disinfectant composition.

[0109] <Comparative Example 4>

[0110] In the above Example 1, the temperature-sensitive polymer was prepared in the same manner as in Example 1, except that 100 parts by weight of poly-N-isopropylacrylamide was used, rather than by mixing 90 parts by weight of poly-N-isopropylacrylamide and 10 parts by weight of polycaprolactam (PCL).

[0111] <Comparative Example 5>

[0112] In the above Example 1, the temperature-sensitive polymer was prepared in the same manner as in Example 1, except that a mixture of 70 parts by weight of poly-N-isopropylacrylamide and 30 parts by weight of polycaprolactam (PCL) was used instead of a mixture of 90 parts by weight of poly-N-isopropylacrylamide and 10 parts by weight of polycaprolactam (PCL).

[0113] For the disinfectant composition having the above composition and content, a final film was obtained after storing it in a refrigerated state at -10℃ for 1 day.

[0114] [Experimental Example 1] Sensory Evaluation

[0115] A 5cm x 3cm film-type disinfectant specimen prepared through the above examples and comparative examples was placed into an open circular cell (10cm x 10cm), heated and rubbed, and then measured through the sense of smell of 20 healthy adult men and women.

[0116] The measurement method utilized the fact that the higher the fragrance intensity value of the measured sample, the more the pungent odor increases in proportion to the intensity of the odor. In other words, a higher fragrance intensity value indicates the presence of an unpleasant odor, while a lower fragrance intensity value indicates that a fragrance remains without any odor. The evaluation criteria for each item were based on a 5-point scale as described below, rounded to the second decimal place.

[0117] ① Scent intensity value

[0118] The degree of fragrance deterioration, off-flavor, and fragrance harmony perceived by the sense of smell were comprehensively evaluated.

[0119] 1: The base and added flavors are harmonious, and there is no off-flavor.

[0120] 2: The base and added flavors are harmonious, and off-flavors are minimal.

[0121] 3: The base scent is average, and the off-flavor is weak.

[0122] 4: Leaves a distinctive pungent odor of chloric acid.

[0123] 5: The characteristic pungent smell of chloric acid is very strong.

[0124] Scent intensity level Example 1 2 Comparative Example 1 4.8 Comparative Example 2 4.2 Comparative Example 3 4.3 Comparative Example 4 3.1 Comparative Example 5 2.9

[0125] As can be seen from Table 3 above, in the case of the disinfectant composition corresponding to Example 1 of the present invention, unlike conventional disinfectants, it was confirmed that even if hypochlorous acid is included, the characteristic pungent odor is not produced by adjusting the weight ratio with the fragrance extract.

[0126] In particular, through the above experiments, it was confirmed that the peculiar odor could not be eliminated when the composition and content of the fragrance extract were changed as in Comparative Examples 1 to 3, and it was confirmed that the peculiar odor could be eliminated by satisfying the composition of the fragrance extract according to the present application.

[0127] [Experimental Example 2] Evaluation of Usability

[0128] A moss sterilization test was conducted by rubbing the film-type disinfectants prepared according to Example 1, Comparative Examples 4 and 5 in the same manner. The results were evaluated by including generally available moss in the films prepared according to Example 1, Comparative Examples 4 and 5, respectively. Moss is a target for evaluating antibacterial ability and has the characteristic of changing color from green to colorless when included in a substance with antibacterial ability.

[0129] In the case of Example 1, the disinfectant composition was applied due to friction, and the color of the moss changed from green to white, confirming that it has excellent antibacterial ability. This is believed to be a result of the disinfectant composition of the present invention satisfying specific composition and content.

[0130] However, in the case of Comparative Examples 4 and 5, the temperature-sensitive polymer according to the present application was not used, and the polymer did not melt sufficiently even with friction and increased temperature, so the disinfectant composition was not easily applied. Consequently, when it was confirmed that the color of the moss changed slightly but still showed green, it was confirmed that the antibacterial ability was reduced.

[0131] [Experimental Example 3] Bacteria Removal Ability Test

[0132] After rubbing the film prepared according to the above examples and comparative examples against the hands of a worker contaminated with microorganisms for 2-3 minutes, and confirming that the moisture had evaporated, the degree of microbial contamination before and after application was measured using a portable microbial contamination measuring device (Model TBD1000, TELTRON, South Korea).

[0133] The above-mentioned microbial contamination measuring device is a portable ATP measuring device, and although the measured contamination level varies depending on the object, it can generally be estimated as dangerous if it is 400 or higher, caution if it is between 200 and 400, and safe if it is less than 200. A detection value of 0 means that no ATP is detected, and therefore it means that microorganisms have been completely removed.

[0134] The experimental results were measured as shown in Table 4 below.

[0135] Before processing After processing Example 1 270 0 Comparative Example 1 200 100 Comparative Example 2 300 80 Comparative Example 3 250 90 Comparative Example 4 270 240 Comparative Example 5 300 260

[0136] As can be seen in Table 4 above, it was confirmed that the film-type disinfectant according to the present application has excellent bacterial removal ability.

[0137] In the case of Comparative Examples 1 to 3, the temperature-sensitive polymer melted and showed some disinfection effect, but it was confirmed that the ability to remove bacteria was lower compared to the examples because the fragrance extract was not used within the range according to the present application.

[0138] In addition, in the case of Comparative Examples 4 and 5, the fragrance extract according to the present application was used, but the temperature-sensitive polymer was not used in the composition of the present application. It was confirmed that in the case of Comparative Examples 4 and 5, the polymer did not melt smoothly even when rubbed against the worker's hand, so the disinfectant was not applied.

[0139] In other words, the film-type disinfectant according to the present invention includes not only an antibacterial effect but also a composition that provides portability, deodorization, and fragrance for convenient application in daily life. This patent application was filed after discovering the effect of effectively reducing the odor of the antibacterial substance while maintaining the existing antibacterial effect within a certain range.
