Abstract

One embodiment of the present specification provides a multipurpose cleaner composition comprising graphene oxide and a nonionic surfactant, and having antibacterial and deodorizing effects.

Description

Multipurpose detergent composition with antibacterial and deodorizing effects

[0001] The present specification relates to a multipurpose detergent composition having antibacterial and deodorizing effects.

[0002] Conventional bathroom cleaners typically contain hydrochloric acid and sodium hypochlorite, which offer excellent cleaning power but are also highly harmful to the human body. Commonly used antibacterial and deodorizing agents include chlorine-based disinfectants like Rox. Rox exhibits powerful antibacterial and deodorizing properties due to the oxygen generated by hypochlorous acid (HClO). However, the toxicity of the chlorine gas produced during use causes discomfort and safety concerns among users, leading to a tendency to avoid using it in indoor spaces such as the kitchen.

[0003] In addition, conventional bathroom liquid detergents tended to use anionic surfactants to provide cleaning performance and foaming properties. However, there is a problem that anionic surfactants generally do not exhibit sufficient removal effects for oily and inorganic stains, which are the main causes of bathroom stains, and stubborn stains. In particular, stains such as water stains and sebum on bathroom tiles or floors, large amounts of moisture and human excrement remaining after bathroom use, which cause the proliferation of many types of bacteria, such as basic amine compounds such as ammonia and trimethylamine, acidic sulfur compounds such as hydrogen sulfide and methyl mercaptan, and odors such as acetaldehyde with a low volatile point, were difficult to remove with conventional bathroom detergents.

[0004] Accordingly, in the past, chemical removal methods using chemical reactions, physicochemical removal methods using adsorption, biochemical removal methods using sterilization, and sensory deodorization methods such as adding fragrance were used for deodorizing effects. However, the antibacterial and deodorizing technologies up to now have focused on masking methods that mainly use fragrances to prevent the occurrence of bad odors, etc., rather than the fundamental removal of the components themselves. Therefore, there was a problem that the bad odor components remained when the fragrances evaporated, and there were many problems such as dispersion problems due to mixing various reagents, compatibility problems between reagents, and pH control problems.

[0005] Therefore, there is a need to develop a multipurpose detergent that is harmless to the human body and can be used in indoor spaces such as the kitchen, has excellent cleaning power, and has excellent antibacterial and deodorizing effects, so that it can also be used as a bathroom detergent.

[0006] The present specification is intended to solve the problems of the prior art described above, and one object of the present specification is to provide a multipurpose detergent composition that has excellent cleaning and antibacterial properties, exhibits a deodorizing effect, and is not harmful to the human body.

[0021] Below, aspects of this specification will be described based on specific examples. However, the contents of this specification may be implemented in various different forms and are therefore not limited to the embodiments described herein.

[0022] Throughout the specification, whenever a part is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless otherwise stated.

[0023] When a range of numerical values ​​is stated herein, unless the specific range is otherwise specified, the values ​​have the precision of the significant figures provided according to the standard rules in chemistry for significant figures. For example, the number 10 includes the range of 5.0 to 14.9, and the number 10.0 includes the range of 9.50 to 10.49.

[0024] Detergent composition

[0025] A detergent composition according to one aspect of the present specification comprises graphene oxide (GO) and a nonionic surfactant.

[0026] The above-mentioned graphene oxide is a material manufactured by oxidizing the surface of graphene. Unlike graphene, it is water-soluble and biodegradable. The above-mentioned graphene oxide may be manufactured through a chemical exfoliation method utilizing the oxidation of graphite, and may be manufactured, for example, using the Hummers method, but is not limited thereto.

[0027] The above-mentioned graphene oxide can exhibit strong antibacterial properties against E. coli, Staphylococcus aureus, etc. through mechanisms such as destruction of harmful bacteria cell membranes through sharp edges, cell peroxidation, and photocatalytic reactions, and at the same time, it can exhibit excellent deodorizing effects due to its adsorption ability against ammonia, amine compounds, acetaldehyde, etc., and can easily secure a detergent formulation due to its excellent water dispersibility properties.

[0028] The content of the above graphene oxide may be 0.001 to 0.5 wt% based on the total weight of the composition. Preferably, it may be 0.01 to 0.3 wt%, and more preferably, 0.05 to 0.15 wt%. If the content of the graphene oxide is less than the above range, it may be difficult to exhibit the antibacterial and adsorption mechanisms, which may reduce the antibacterial and deodorizing effects of the detergent composition, and its cleaning power against contamination may be reduced. If the content of the graphene oxide exceeds the above range, the acidity of the composition may become strong, and cost-effectiveness may be reduced.

[0029] The above graphene oxide may be included in the form of an aqueous solution when preparing a detergent composition. For example, graphene oxide prepared by a chemical exfoliation method may be included in the form of an aqueous solution, but is not limited thereto.

[0030] The above-mentioned detergent composition can exhibit excellent cleaning power, antibacterial power, and deodorizing effects by including graphene oxide, which has both antibacterial power and deodorizing power through adsorption, and by using a nonionic surfactant together.

[0031] The above nonionic surfactant may be one selected from the group consisting of polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene alkylphenyl ether, fatty acid polyglycerin ester, fatty acid sucrose ester, fatty acid alkanolamide, alkylamine oxide, amideamine oxide, and a combination of two or more thereof, but is not limited thereto.

[0032] The content of the nonionic surfactant may be 0.1 to 5 wt% based on the total weight of the composition. Preferably, it may be 0.1 to 3 wt%, and more preferably, it may be 0.1 to 1 wt%. If the content of the nonionic surfactant is less than the above range, the cleaning power and antibacterial power of the detergent composition may be reduced, and the dispersion of graphene oxide within the composition may be reduced. If the content of the nonionic surfactant exceeds the above range, the formulation stability may be reduced.

[0033] The weight ratio of the above graphene oxide and the nonionic surfactant may be 1:1 to 10. Preferably, it may be 1:2 to 8, and more preferably, 1:4 to 6. If the weight ratio of the above graphene oxide and the nonionic surfactant is outside the above range, the cleaning power and antibacterial power of the detergent composition may be reduced, or the dispersion of the graphene oxide within the composition may be reduced, resulting in reduced formulation stability.

[0034] The above detergent composition may further include an anionic surfactant.

[0035] The above anionic surfactant may be one selected from the group consisting of alkyl polyoxyethylene sulfate salts, alkyl sulfate salts, alkylbenzene sulfonate salts, α-olefin sulfonate salts, fatty acid salts, α-sulfonic acid fatty acid salts, ether carboxylate salts, alkyl phosphate salts, alkyl polyoxyethylene phosphate salts, dialkyl sulfosuccinic acid ester salts, alkyl sulfosuccinic acid salts, alkenyl succinate salts, N-acylamino acid salts, N-acylmethyl taurate salts, and combinations of two or more thereof, but is not limited thereto.

[0036] The content of the anionic surfactant may be 1 to 10 wt% based on the total weight of the composition. Preferably, it may be 1 to 5 wt%, and more preferably, 1 to 2 wt%. If the content of the anionic surfactant is less than the above range, the cleaning power of the detergent composition may be reduced, and if it exceeds the above range, excessive foaming may occur, which may reduce the stability of the formulation.

[0037] The weight ratio of the nonionic surfactant to the anionic surfactant may be 1:1 to 10. Preferably, it may be 1:1 to 5, and more preferably, 1:2 to 4. If the weight ratio of the anionic surfactant to the nonionic surfactant is less than the above range, the cleaning power or formulation stability of the detergent composition may be reduced, and if it exceeds the above range, the cleaning power and antibacterial power of the detergent composition may be reduced, or the dispersion of graphene oxide in the composition may be reduced, thereby reducing the formulation stability.

[0038] The above detergent composition may further include one selected from the group consisting of a pH adjuster, a fragrance, a solubilizer, a cleaning alkali, a preservative, and a combination of two or more thereof.

[0039] The above detergent composition may further comprise 0.01 to 0.5 wt% of a pH regulator based on the total weight of the composition. Preferably, the pH regulator may further comprise 0.01 to 0.3 wt%, more preferably 0.05 to 0.15 wt%. If the content of the pH regulator is below the above range, the pH regulator function may be reduced, and if it exceeds the above range, the acidity of the composition may increase or problems with the formulation may occur.

[0040] The pH adjuster may be, but is not limited to, citric acid, which can reduce the water path as a metal chelating agent to increase the efficiency of the detergent and also play a role in removing stains or rust from the metal surface, acetic acid, which can eliminate bacteria and mold and have a deodorizing effect, or a combination thereof.

[0041] The above detergent composition may further comprise 0.01 to 1 wt% of a fragrance based on the total weight of the composition. Preferably, the composition may further comprise 0.01 to 0.5 wt%, and more preferably, 0.05 to 0.3 wt% of a fragrance.

[0042] The above fragrances include hydrocarbons such as aliphatic hydrocarbons, terpene hydrocarbons, and aromatic hydrocarbons, alcohols such as aliphatic alcohols, terpene alcohols, and aromatic alcohols, ethers such as aliphatic ethers and aromatic ethers, oxides such as aliphatic oxides and terpene oxides, aldehydes such as aliphatic aldehydes, terpene aldehydes, hydrogenated aromatic aldehydes, thioaldehydes, aromatic aldehydes, and aliphatic aldehydes, ketones such as aliphatic ketones, terpene ketones, hydrogenated aromatic ketones, aliphatic cyclic ketones, non-benzene aromatic ketones, and aromatic ketones, acetals, ketals, phenols, phenol ethers, fatty acids, terpene carboxylic acids, hydrogenated aromatic carboxylic acids, and aromatic carboxylic acids, acid amides, aliphatic lactones, and macrocyclic Lactones such as lactones, terpene lactones, hydrogenated aromatic lactones, aromatic lactones, etc., aliphatic esters, furan carboxylic acid esters, aliphatic cyclic carboxylic acid esters, cyclohexylcarboxylic acid esters, terpene carboxylic acid esters, aromatic carboxylic acid esters, etc., nitrogen-containing compounds such as nitromusks, nitriles, amines, pyridines, quinolines, pyrrols, indoles, etc., synthetic fragrances, or natural fragrances taken from animals or plants can be used alone or in combination, but are not limited thereto.

[0043] The above-mentioned detergent composition may further comprise 0.01 to 2 wt% of a preservative, based on the total weight of the composition. Preferably, the preservative may further comprise 0.01 to 1 wt%, and more preferably, 0.01 to 0.5 wt%. If the preservative content is below the above range, the preservative performance may be lost, and if it exceeds the above range, the formulation may be problematic.

[0044] The above preservative may be one selected from the group consisting of methylparaben, ethylparaben, propylparaben, benzoic acid, sodium benzoate, isothiazolinone, a formaldehyde releaser, sorbic acid, and a combination of two or more thereof, or a salt thereof, but is not limited thereto.

[0045] The above-mentioned detergent composition may further comprise 0.1 to 5 wt% of a detergent alkali based on the total weight of the composition. Preferably, it may further comprise 0.1 to 3 wt%, more preferably 0.1 to 1 wt% of a detergent alkali. If the content of the detergent alkali is below the above range, the cleaning power may be reduced, and if it exceeds the above range, it may exhibit alkalinity and cause a neutralization reaction with the graphene oxide aqueous solution, resulting in the loss of the detergent's inherent properties or reduced dispersibility.

[0046] The above cleaning alkali may be one selected from the group consisting of sodium hydroxide, potassium hydroxide, ammonium hydroxide, sodium carbonate, sodium silicate, and a combination of two or more thereof, but is not limited thereto.

[0047] A detergent composition containing a cleaning alkali has a better cleaning power than a composition not containing the cleaning alkali, and thus can be suitably used in spaces with a high degree of contamination, such as restrooms and bathrooms, and a detergent composition not containing a cleaning alkali can be suitably used in living spaces, such as kitchenware or home appliances, that are frequently touched by human hands.

[0048] The above-described detergent composition may further comprise 1 to 10 wt% of a solubilizer based on the total weight of the composition. Preferably, the solubilizer may further comprise 3 to 7 wt%, more preferably 4 to 6 wt%. If the content of the solubilizer is below the above range, the dissolution of graphene oxide may be difficult, making it difficult to secure a formulation. If the content of the solubilizer exceeds the above range, the concentration of graphene oxide may be low, making it difficult to exhibit its function.

[0049] The above-mentioned solvent may be one selected from the group consisting of propylene glycol methyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether, propylene glycol methyl ether acetate, propylene glycol N-propyl ether, dipropylene glycol n-propyl ether, tripropylene glycol n-propyl ether, propylene glycol n-butyl ether, dipropylene glycol n-butyl ether, tripropylene glycol n-butyl ether, propylene glycol diacetate, dipropylene glycol dimethyl ether, 3-methyl-3-methoxy butanol, ethanol, and a combination of two or more thereof, but is not limited thereto.

[0050] The above detergent composition may further comprise a residual amount of water. In one embodiment, the detergent composition may use only water as a solvent, and in another embodiment, the detergent composition may use a solvent that is a mixture of water and the solvent.

[0051] The above detergent composition may be in liquid form or may be formulated as a spray type, but is not limited thereto.

[0052] The above-mentioned detergent composition can exhibit excellent antibacterial activity against harmful bacteria such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans. In particular, the detergent composition can exhibit high antibacterial activity, with a 99.9% reduction in E. coli concentration after 24 hours of use.

[0053] The above-mentioned detergent composition is a multi-purpose detergent composition having excellent cleaning power and antibacterial effect, and can be used to remove various contaminants and harmful bacteria in bathrooms such as bathtubs, sinks, tiles, toilets, and bathroom floors, as well as in living spaces such as kitchenware and home appliances, but is not limited thereto, and can be used in various fields requiring cleaning and antibacterial properties. In one embodiment, the detergent composition may be a detergent composition for a bathroom.

[0054] The above detergent composition can exhibit an effective deodorizing effect on ammonia, amine, hydrogen sulfide and mercaptan, which are major causes of odor, and can exhibit good formulation stability when stored at low and high temperatures.

[0055] The above detergent composition can have high biodegradability, low skin irritation, and excellent price competitiveness.

[0069] Experimental example

[0070] Experimental Example 1: Evaluation of Cleaning Power

[0071] Based on ASTM D-5343-97, a method for measuring the cleaning power of mixed artificial contamination of oily and inorganic contamination, which are the main sources of contamination in living rooms and indoor spaces, an artificial contamination for bathrooms with the following composition was manufactured.

[0072] < Artificial pollution composition (meteor pollution + inorganic pollution) >

[0073] - Synthetic Sebum Soil: Palmitic acid, stearic acid, coconut oil, paraffin wax, olive oil, squalene, cholesterol, oleic acid, sodium stearate

[0074] - Inorganic contaminants: calcium stearate, magnesium stearate, iron stearate

[0075] After melting 0.5 g of the manufactured artificial contamination for bathrooms at 80°C, it was evenly applied to bathroom tile specimens (20 cm x 20 cm) and metal specimens (5 cm x 5 cm), respectively, and the applied specimens were dried with hot air at 50°C for 24 hours to prepare contamination specimens.

[0076] The manufactured contaminated specimens were immersed in a container containing 150 g of the detergent compositions of Examples 1 and 2 and Comparative Examples 1 to 4 for 10 minutes, and vibrated at 1000 rpm for 2 minutes in a vortex mixer. Thereafter, the contaminated specimens were taken out, washed in running water for 30 seconds, dried using a dryer for 1 minute, and then naturally dried at 25°C for 3 hours.

[0077] The bathroom tile specimens were observed on the surface after drying, and the metal specimens were weighed before and after drying to determine the contamination removal rate, and the average value of five repetitions was determined as the cleaning rate (%).

[0078] Experimental Example 2: Antibacterial activity evaluation

[0079] According to the antibacterial test method KCL-FIR-1003, the detergent compositions of Examples 1 and 2 and Comparative Examples 1 to 4 were sprayed onto nonwoven fabric, and the reduction rate (%) of E. coli concentration (CFU / mL) was measured after 24 hours.
