Description

Technology Field

[0001] The present invention relates to a low-irritation antibacterial deodorizing composition, and more specifically, to an antibacterial deodorizing composition having low irritation, antibacterial properties and cleaning power comprising ethanol, laurylpyridinium chloride, a nonionic surfactant, methyl hydrogenated rosinate, and menthyl acetate, and an antibacterial deodorizing agent comprising the same. Background Technology

[0002] Deodorization is the removal of gas molecules that cause odors, and generally involves a mechanism of removing deodorizing gases by adsorption, or through chemical or combustion reactions. Such deodorizers are widely used in refrigerators, bathrooms, shoe cabinets, and other areas.

[0003] Among these, chemical deodorization methods remove odor gases by oxidizing and decomposing them, and highly reactive substances such as chlorine and ozone are used as deodorizers. A representative deodorizing substance is chlorine dioxide, which is mainly contained in gel-type odor removers and removes odors by releasing chlorine gas as it slowly volatilizes.

[0004] Generally, refrigerators, bathrooms, and shoe cabinets where deodorizers are used contain not only foul odors but also large quantities of microorganisms such as bacteria and unsanitary, harmful contaminants; therefore, cleaning agents containing antibacterial or sterilizing ingredients are added to maintain a hygienic state.

[0005] For example, conventionally, products (such as bleach) containing hydrochloric acid (HCl), a type of strong acid, as the main ingredient were mainly used to disinfect and sterilize microorganisms. However, while hydrochloric acid sterilizes based on its strong oxidizing power and the resulting disinfection effect, it not only causes severe corrosion but also has problems such as dermatitis and bad odors when it comes into contact with the skin during use.

[0006] In addition, existing toilet or bathroom cleaners produced a white precipitate when diluted in hard water, leading to problems such as stains forming or the precipitate remaining after use. The problem to be solved

[0007] The present invention provides an antibacterial and deodorizing composition that can solve environmental problems by reducing the use of hydrochloric acid, phosphoric acid, or harmful substances, while also providing antibacterial or sterilization functions.

[0008] The present invention provides an antibacterial and deodorizing composition with excellent cleaning power that dissolves well in water and leaves no precipitates or stains.

[0009] The present invention provides an antibacterial and deodorizing composition that can be used as a bathroom cleaner as well as a hand sanitizer. means of solving the problem

[0010] In one embodiment, the present invention

[0011] Ethanol 10~20 wt% ;

[0012] Laurylpyridinium chloride 5~15 wt%;

[0013] 20-40% by weight of a nonionic surfactant;

[0014] 5-15 wt% methyl hydrogenated rosinate;

[0015] Mentyl acetate 10~20 wt%; and

[0016] The present invention relates to an antibacterial deodorizing composition comprising 5 to 15 weight percent of a viscosity modifier.

[0017] In another aspect, the present invention relates to an antibacterial deodorizer comprising 0.1 to 15 parts by weight of the antibacterial deodorizing composition in 100 parts by weight of water. Effects of the invention

[0018] The fragrance deodorizing composition of the present invention can reduce environmental problems or human health hazards by using methyl hydrogenated rosinate, which has low toxicity and low vapor pressure, as a fragrance, and laurylpyridinium chloride and ethanol, which have excellent antibacterial and sterilizing effects and low irritation, as disinfectants.

[0019] The composition of the present invention can provide a deodorizing agent with excellent cleaning power that does not leave precipitates or stains by using polyoxyethylene (23) lauryl ether, which is a nonionic surfactant, and at the same time including a fragrance and a disinfectant that have high solubility in water. Specific details for implementing the invention

[0020] The present invention can be fully achieved by the following description. The following description should be understood as describing preferred embodiments of the present invention, but the present invention is not necessarily limited thereto. Furthermore, the attached drawings are for illustrative purposes only and do not limit the present invention; details regarding individual components can be appropriately understood in accordance with the specific intent of the relevant descriptions provided below.

[0021] Terms used in this specification may be defined as follows.

[0022] When a component is said to "include," it means that, unless otherwise noted, it may include additional components and / or steps.

[0023] The antibacterial deodorizing composition of the present invention comprises ethanol, a nonionic surfactant, methyl hydrogenated rosinate, menthyl acetate, laurylpyridinium chloride, and a viscosity modifier.

[0024] The above ethanol is used as a solvent and a disinfectant (antibacterial) component. The above ethanol may be used in an amount of 10 to 20 weight percent in the antibacterial deodorizing composition.

[0025] Generally, when ethanol is present in ethanol-based disinfectants at a concentration of 60% by weight or more, it exhibits broad-spectrum antibacterial efficacy against bacteria, viruses, parasites, and fungi, but safety issues such as inhalation by humans due to ethanol vaporization have been raised. On the other hand, when ethanol is present in a concentration of 40% by weight or less, the antibacterial activity decreases rapidly.

[0026] The composition of the present invention uses 10 to 20 weight percent of ethanol, which is lower than 40 weight percent, and contains 5 to 15 weight percent of laurylpyridinium chloride, which is used as an antimicrobial agent or preservative, thereby maintaining the antimicrobial properties of the composition while simultaneously reducing irritation to the human body (skin or eyes) caused by vaporization.

[0027] In addition, the above laurylpyridinium chloride has a short carbon number, so it has excellent solubility and diffusivity in water, and has a lower vapor pressure compared to ethanol, which can reduce irritation to the human body.

[0028] The above laurylpyridinium chloride can also perform a deodorizing function.

[0029] If the above laurylpyridinium chloride is included in an amount of less than 5 weight%, the bactericidal power may be weakened.

[0030] In addition, the total weight of the laurylpyridinium chloride with ethanol may be 35% by weight or less. If it exceeds 35% by weight, the bactericidal power may increase, but the degree of skin irritation may increase.

[0031] The above composition may contain 20 to 40 weight percent of a surfactant. The surfactant may be a cationic surfactant, an anionic surfactant, or a nonionic surfactant.

[0032] Cationic surfactants may be selected from dodecyl ammonium chloride, cetyltrimethylammonium bromide, alkylammonium methosulfate, alkyldimethylammonium chloride, and mixtures thereof.

[0033] The above anionic surfactant may be selected from sodium stearate, sodium laurate, sodium palmitate, potassium stearate, potassium laurate, potassium palmitate, sodium lauryl sulfate, sodium dodecylbenzene sulfonate, and mixtures thereof.

[0034] The above nonionic surfactant may be a polyoxyethylene alkyl ether, a fatty acid sorbitan ester, a fatty acid diethanolamine, or an alkyl monoglyceryl ether, and preferably a polyoxyethylene (23) lauryl ether, which is a polyoxyethylene-based surfactant.

[0035] The above nonionic surfactant has the advantage of being able to act as a surfactant even at low concentrations compared to ionic surfactants and causing less skin irritation. Therefore, a nonionic surfactant is preferred as the surfactant. In addition, among nonionic surfactants, the above polyoxyethylene (23) lauryl ether, which has excellent compatibility with ethanol and laurylpyridinium chloride, is most preferred.

[0036] The composition of the present invention may use 5 to 15 weight% of the methyl hydrogenated rosinate and 10 to 20 weight% of menthyl acetate as fragrances.

[0037] The above methyl hydrogenated rosinate may be an ester of methyl alcohol and hydrogenated alliclic acid derived from rosin. The above methyl hydrogenated rosinate may be a naturally derived ingredient.

[0038] The above methylhydrogenated rosinate is a fragrance with low vapor pressure and low irritation. In particular, the above methylhydrogenated rosinate has excellent solubility in ethanol or water.

[0039] The above-mentioned menthyl acetate is a fragrance component with a soft mint and rose scent, and when the composition is diluted in water and sprayed or used as a cleaning agent, it can block the odor of ammonium or chlorine and provide a mint scent.

[0040] The antibacterial deodorizing composition of the present invention may further include 1 to 5 weight% limonene, 1 to 5 weight% menthol, 1 to 5 weight% dihydromyrcenol, and 0.1 to 1 weight% hexyl cinnamic aldehyde as fragrances.

[0041] The antibacterial deodorizing composition of the present invention may contain 5 to 15 weight percent of a viscosity modifier. If the viscosity modifier is included in a small amount, it may be difficult to ensure the stability of the formulation. The viscosity modifier may be one or more selected from the group consisting of hexylene glycol, hydrated silica, silica dimethicone silylate, silica dimethyl silylate, silica silylate, silica caprylyl silylate, silica cetyl silylate, hydrogenated styrene / isoprene copolymer, silica dimethyl silylate, and hydrogenated styrene / butadiene copolymer, and preferably hexylene glycol.

[0042] The hexylene glycol above is an aliphatic alcohol and can reduce the viscosity of the composition. In addition, the hexylene glycol also has an odor removal function and a solvent function.

[0043] In another aspect, the present invention relates to an antibacterial deodorizing agent comprising 0.1 to 20 parts by weight, preferably 0.1 to 15 parts by weight, of the antibacterial deodorizing composition in 100 parts by weight of water.

[0044] More specifically, the antibacterial deodorizer may be used as a fragrance, bathroom or kitchen cleaner by including 5 to 15 parts by weight, preferably 5 to 12 parts by weight, of the antibacterial deodorizing composition in 100 parts by weight of water.

[0045] In addition, the above antibacterial deodorizer can be used as a hand cleanser, cosmetic composition, air freshener, or bathroom or kitchen cleaner by including 0.1 to 5 parts by weight, preferably 0.5 to 2 parts by weight, of the above antibacterial deodorizing composition in 100 parts by weight of water.

[0046] Since the above antibacterial deodorizing composition is highly soluble in water, a solubilizing agent is not separately added to the antibacterial deodorizing agent. Furthermore, the above antibacterial deodorizing agent has excellent antibacterial and sterilization effects and cleaning power, while causing minimal skin irritation, so it can be used in hand sanitizers or cosmetic compositions.

[0048] The present invention will be explained in more detail below through examples, but the present invention is not limited to these examples.

[0067] Cleaning power test

[0068] 5g of the antibacterial deodorizer prepared in the examples and comparative examples was placed in a spray container and sprayed onto a whiteboard written with a water-based pen and an oil-based pen, respectively, and wiped with a wet tissue. The degree of wiping is indicated in Table 2 below.

[0069] 5: Excellent, 4: Good, 3: Average, 1: Poor

[0071] Deodorization test

[0072] Nine beakers containing 5g of a 2ppm ammonia solution were prepared. 5g of the antimicrobial deodorizer prepared in the example and comparative example was poured into eight beakers and mixed. One beaker was not mixed with the antimicrobial deodorizer. The evaluation was conducted on 10 adult men and women. The evaluators compared the odor of the beaker without the antimicrobial deodorizer with the beaker mixed with the example and comparative example. The degree of deodorization was evaluated as follows and is shown in Table 2 below.

[0073] 5: Almost no odor, 4: Odor reduced by about 60~80%,

[0074] 3: Odor reduced by approximately 30–60%, 1: Almost similar to the initial state

[0076] Eye irritation test

[0077] Beakers containing 5g of the antibacterial deodorizer prepared in the examples and comparative examples were prepared, respectively. The evaluation was conducted on 10 adult men and women, and the evaluators were instructed to smell the odor for 1 minute while maintaining a distance of 30 cm from the beaker. The level of irritation to the eyes and respiratory system was rated on a scale of 1 to 5.

[0088] Examples 1 to 4 significantly increased the viable cell count of E. coli (10) by adding 5% by weight or more of laurylpyridinium chloride, even though ethanol was used at a low level of 15 to 20% by weight. 3 It was possible to reduce the number of viable bacteria by more than 99%. In addition, Examples 1 and 5 reduced the number of viable bacteria by more than 99%. In contrast, Comparative Example 2 had a low bactericidal effect due to the small amount of ethanol and laurylpyridinium chloride, which were the disinfectants.

[0089] In Examples 2, 4, 5, and 6, writing written with water-based and oil-based pens was easily erased in a single pass, whereas in Comparative Example 1, writing written with an oil-based pen could be erased by wiping it repeatedly. Examples 1 and 3 showed cleaning power intermediate between that of Example 2 and Comparative Example 1.

[0090] In Examples 1 to 3, the ammonia odor was significantly reduced, while in Example 4, a slightly unpleasant ammonia odor remained. On the other hand, in Comparative Examples 2 to 4, the ammonia odor was easily detectable. In contrast, in Examples 5 and 6, the ammonia odor was barely detectable.

[0091] Examples 1 to 4 caused minimal skin irritation, while Examples 5 and 6 caused slight irritation. Comparative Example 4 caused significant irritation, such as itching or stinging of the wrist.
