Description

  The present invention relates to a paste-like cleaning composition having antibacterial properties, comprising sodium bicarbonate as a cleaning component.

Conventionally, a surfactant, an inorganic alkaline cleaner, or an organic acid cleaner has been used as a main component of the cleaner depending on the nature of the dirt. The term “detergent” is mainly used when a surfactant is a main component, and may be used separately from a cleaning agent that means a component that exhibits a cleaning effect. The term “cleaning agent” is used as a component capable of exerting a cleaning effect.
As a component of the inorganic alkaline detergent, sodium hydrogen carbonate (NaHCO ₃ , also known as sodium bicarbonate, or sodium bicarbonate, hereinafter sometimes referred to as sodium bicarbonate), sodium carbonate (Na ₂ CO ₃ ), sodium percarbonate (2Na ₂ CO ₃ .3H ₂ O ₂ ) and sodium sesquicarbonate (Na ₂ CO ₃ .NaHCO ₃ ) are known. These inorganic alkaline detergents are generally inferior in washing power of clothes, etc., compared to detergents containing surfactants, but can be easily rinsed and exhibit their unique cleaning effect, It is known to be used for washing, removing dirt from oil, removing burnt from pots, bath additives, etc. In Japan, during the Edo period and during World War II, when supplies were scarce, potassium carbonate (K ₂ CO ₃ ), the main ingredient of ash, was extracted from plant ash and used for washing. There is a background.

The characteristics of baking soda compared to other inorganic alkaline detergents are that the pH value of the aqueous solution is somewhat low and the solubility in the aqueous solution is considerably low.
When used as an inorganic alkaline detergent component, the aqueous solution pH of sodium carbonate and potassium carbonate is about 11.2 to 11.6 at 20 ° C., the aqueous solution pH of sodium percarbonate is about 10 to 11, and sodium sesquicarbonate. PH of aqueous sodium bicarbonate solution at 20 ° C. is relatively about 8.4 to 8.0 at a concentration of 1 to 50 g / liter of water (L). It is weakly alkaline. An aqueous solution of sodium bicarbonate is easy to handle because it has a weaker alkaline pH than other inorganic alkaline detergents. Baking soda is a natural material that exists in nature and has a low environmental impact on rivers and seas. As a result, awareness of the natural environment has been increasing for about 30 to 40 years ago. Various usages that focus on the effects have been devised.

  In general, alkaline detergents can remove sebum, protein stains, and oil stains. Sebum that adheres to clothing is usually mostly composed of triglycerides and free fatty acid components. When this sebum soil is washed with an alkaline detergent, the sebum is saponified into glycerin and soap, and is detached from the clothing and dissolved in the aqueous phase. In addition, sweat, dirt, dirt such as blood adhering to clothing, and food dirt such as meat and fish are composed of protein components, and the protein is a high chain formed by linking many L-amino acids in a chain. It is a molecular compound. The soil polymer compound is disconnected or weakened by an alkaline cleaner, and is detached from the clothing fiber and washed away. Baking soda is weakly alkaline compared to sodium carbonate and sodium sesquicarbonate, so it can be used for light dirt removal, but it is desirable to use sodium carbonate, sodium sesquicarbonate, or a surfactant when the dirt is severe. .

The feature of baking soda is that the pH is relatively low, the solubility in water is relatively low compared to other alkaline detergents, the surface is relatively soft in the particle state, and the surface of the object to be cleaned is Utilizing the point that it is difficult to damage, the point that baking soda fine particles can exert the polishing action, etc., dissolve the baking soda in a relatively small amount of water and paste it on the surface of the dirty part of the object to be cleaned, then use a sponge, brush, etc. By rubbing, it becomes possible to remove stubborn oil stains and the like. Further, when baking soda is used as a cleaning agent, a polishing agent or the like, it is difficult to adhere to the surface of the object to be cleaned if it is in a powder form.
Therefore, when baking soda is used as a cleaning agent, etc., either sodium bicarbonate water in which sodium bicarbonate powder is completely dissolved in an aqueous solution or sodium bicarbonate paste obtained by mixing sodium bicarbonate with a small amount of water is used according to the intended use. It is possible.

  The following Patent Document 1 discloses a cleaning agent containing a small amount of fatty acid or fatty acid salt in a sodium hydrogen carbonate aqueous slurry, and the following Patent Document 2 includes sodium bicarbonate particles having a specific average particle size and particle size distribution, and A scrubbing detergent composition having a specific viscosity in a slurry containing a fatty acid or a fatty acid salt and a dispersion medium is disclosed. Patent Document 3 listed below contains sodium hydrogen carbonate and a surfactant, and the carbonic acid carbonate. A detergent composition is disclosed in which at least a portion of sodium hydride is present in a solid state.

On the other hand, since baking soda does not have antibacterial properties, an antibacterial agent is added to a cleaning composition containing baking soda as a main component in order to impart antibacterial properties against gram-negative bacteria, gram-positive bacteria, etc. during storage and use. It is desirable to contain an agent.
The term “antibacterial” is generally used to mean suppressing or inhibiting the growth of bacteria, and the term “bactericidal” is generally used to mean killing or inhibiting the growth of bacteria. Antibacterial agents have a slightly different meaning from fungicides, but are often treated as synonyms. However, since the expression “sterilization” cannot be used for “miscellaneous goods” such as detergents and bleaches in the Pharmaceutical Affairs Law, the term “antibacterial” is mainly used in this specification. In addition, “sterilization” is generally used to reduce the number of microorganisms in a limited space and increase cleanliness. According to the Ministerial Ordinance of the Food Sanitation Act, “ This refers to the removal of microorganisms that are present in food and that can develop. "

  Antibacterial agents are generally classified into two types: inorganic antibacterial agents and organic antibacterial agents. As the inorganic antibacterial agent, those utilizing the bacteriostatic action of metal ions such as silver, copper and zinc compounds, among which silver ions having excellent effects are mainly used. On the other hand, organic antibacterial agents are further divided into natural antibacterial agents and synthetic antibacterial agents. Natural antibacterial agents are derived from plants such as catechin and mustard, and those derived from animals and fish such as chitin and chitosan. It has been. Synthetic antibacterial agents include biguanides, quaternary ammonium salts, pyridinium, pyridine, quinoline, disulfide, oxazoline, triazole, hydantoin, pyrithione, morpholine, and diphenyl ether. ing.

The following Patent Document 4 discloses a cleaning composition comprising an inorganic carrier in which silver bicarbonate, which is an inorganic antibacterial agent, is supported on sodium bicarbonate, which is a cleaning component, and the following Patent Document: No. 5 discloses an antibacterial detergent in which a detergent component containing bicarbonate contains an inorganic carrier on which metal ions that are inorganic antibacterial agents are supported and catechins that are organic antibacterial agents. ing.

In Patent Document 7 below, a functional component having a bactericidal and antibacterial effect is added to a copolymer obtained from a surfactant and four types of vinyl monomers as benzalkonium chloride, triclosan, cetylpyridinium chloride, and benzaza chloride. A liquid detergent composition for clothing containing at least one selected from luconium, benzethonium chloride, hinokitiol, and trichlorocarbanilide is disclosed.

Patent Document 8 listed below discloses a disinfectant cleaning composition in which triclosan and isopropylmethylphenol are contained in a surfactant and a solvent comprising an amino acid surfactant or an alkyl ether carboxylate.
In an example of the following Patent Document 9, a detergent composition containing a surfactant as a detergent component has two pyridine rings or quinoline rings at the molecular ends, and the nitrogen atom of these rings is the fourth. Four kinds of antibacterial agents having a quaternary ammonium group (one of the antibacterial agents includes chemical name: 1,4-bis (3,3 ′-(1-decylpyridinium) methyloxy) butanedibromide ( (Hereinafter may be abbreviated as DPMBB)) and was formulated in a concentration of 1% by mass (10,000 ppm by mass) in the test solution. Is disclosed. Patent Document 10 below discloses that the DPMBB is effective for inactivating and controlling various viruses.

None of Patent Document 1 to Patent Document 3 discloses a paste-like cleaning composition having sterilizing properties or antibacterial properties. In addition, Patent Documents 4 and 5 disclose that metal ions, metal ions, and catechins are used as cleaning agents for antibacterial agents, respectively, but in the disclosed metal ion antibacterial agents, metal ions are carriers. Since it is stabilized in a three-dimensional framework structure such as zeolite, it is necessary to consider the uniform dispersibility in a detergent aqueous solution, and natural organic antibacterial agents themselves may not have sufficient antibacterial properties. is there.
The above Patent Documents 6 to 8 disclose a detergent solution containing a surfactant as a main component, but it is effective for a paste-like cleaner composition mainly containing sodium bicarbonate, which is an inorganic alkaline cleaner. Synthetic antibacterial agents are not disclosed.

  Patent Document 9 discloses that antibacterial properties are exhibited when DPMBB is blended at a relatively high concentration (10,000 ppm by mass) in a detergent mainly composed of a surfactant. Patent Document 10 discloses that the DPMBB can exhibit antibacterial activity as an aqueous solution or water emulsion. Therefore, in any of the above Patent Documents 1 to 10, a paste-like detergent composition mainly composed of baking soda, which is an inorganic alkaline detergent component, has excellent antibacterial properties in a low concentration and in a short time. An antibacterial agent that exhibits an effect has not yet been disclosed.

  Non-patent document 1 describes that DPMBB exhibits bacteriostatic and bactericidal activity against bacteria and fungi, and non-patent document 2 describes DPMBB as (i) a medical environment disinfectant and (ii) a paint. It is disclosed that it can be used as an antibacterial / antifungal agent, (iii) a disinfectant for medical optical instruments, (iv) a cooling water, a disinfectant, and an antibacterial / antifungal / antiviral agent for fibers. In both cases, an antibacterial agent that exhibits an excellent antibacterial effect in a short time even in a low concentration is added to a paste-like detergent composition mainly composed of baking soda which is an inorganic alkaline detergent component. This is not disclosed.

  The present invention uses baking soda that has little influence on the environment as a cleaning agent component, and is extremely easy to rinse after cleaning, and is highly safe for the human body. An object is to provide a paste-like cleaning composition.

As a result of intensive studies in view of the above circumstances, the present inventors have found that a small amount of an antibacterial agent represented by the following chemical formula is contained in a paste-like detergent composition containing baking soda as a detergent component, even in weak alkalinity. As a result, it was found that an excellent antibacterial effect was exhibited in a short time, and the present invention was completed. That is, the gist of the present invention is the invention described in the following (1) to (5).
(1) A paste-like cleaning composition containing sodium bicarbonate as a cleaning component and an antibacterial agent (A) represented by the following formula in an aqueous solution,
The paste-like detergent, wherein the content of sodium hydrogen carbonate in the paste-like detergent composition is 50 to 85% by mass, and the content of the antibacterial agent (A) is 0.075% by mass or more. Composition.

(3) The paste-like cleaning composition according to (1) or (2), wherein the content of the antibacterial agent (A) in the paste-like cleaning composition is 0.15 to 0.40% by mass. .
(4) 5 minutes in the paste-like cleaning composition in which the content of the sodium hydrogen carbonate is 55 to 80% by mass and the content of the antibacterial agent (A) is 0.15 to 0.40% by mass The sterilization rate of Escherichia coli and Staphylococcus aureus ([(initial viable count−viable count after 5 minutes) / initial viable count] × 100 (%)) is 99% or more, The paste-like cleaning composition according to any one of 1) to (3).
(5) The pasty detergent composition according to any one of (1) to (4), wherein a foaming agent or a thickener is further contained in the pasty detergent composition.

Since the paste-like cleaning composition of the present invention uses weak alkaline baking soda that has little influence on the environment as a component that exhibits detergency, it is excellent in handling and has a polishing action, and is rinsed after cleaning. Very easy. In addition, by incorporating DPMBB, which is a gemini-type pyridinium-based antibacterial agent having two pyridinium salts in the molecule as an antibacterial agent, the paste-like cleaning composition of the present invention is excellent even in a relatively small amount in a short time. It is possible to exert antibacterial effects.
Further, as described in Non-Patent Document 1, DPMBB, which is a gemini-type pyridinium-based antibacterial agent, is excellent in water solubility, thermal stability, and durability, and therefore contains DPMBB as an antibacterial agent (A). The pasty detergent composition of the present invention can be expected to be easy to handle and excellent in thermal stability and sustainability.

Below, the paste-form cleaning composition of this invention is demonstrated.
The paste-like cleaning composition of the present invention (hereinafter sometimes simply referred to as “paste-like cleaning composition”) includes an aqueous solution, sodium bicarbonate as a cleaning component, and an antibacterial agent represented by the following formula: It is a paste-like cleaning composition containing (A), wherein the content of sodium hydrogen carbonate in the paste-like cleaning composition is 50 to 85% by mass, and the content of the antibacterial agent (A) is It is 0.075 mass% or more.

  Even when sprinkled with baking soda powder when cleaning the surface of the soiled part of the object to be cleaned, it is difficult to adhere to the surface of the dirt. Therefore, it becomes easier to remove dirt, and an excellent antibacterial action can be exhibited in a short time.

(1) About sodium bicarbonate (Baking soda) Baking soda is a white powder of molecular formula NaHCO ₃ , and is defined by the Food Sanitation Law (applicable only to food additives), the Pharmaceutical Affairs Law (applicable only to the pharmacopoeia), and feed additive standards. There is a grade.
The aqueous solution of baking soda is weaker alkaline than the other alkaline detergents sodium carbonate and sodium sesquicarbonate. Specifically, at 20 ° C., the concentration of sodium bicarbonate in 1 liter (L) of water is 1 g. pH 8.4, pH 8.4 at 5 g, pH 8.3 at 10 g, pH 8.2 at 15 g, pH 8.2 at 20 g, 8.1 at 30 g, 8.1 at 40 g It is a weak alkaline substance. . Since it is weakly alkaline in this way, the pH of the aqueous solution is within the range of drainage standards (sea area: within 5.0 to 9.0, other than sea area: within 5.8 to 8.6). can do.

Since baking soda has a very low environmental impact even if it is discharged into rivers or seawater, it is used as a natural cleaning material that is cleaned and washed using safe materials such as baking soda, vinegar, and soap. can do.
The feature of baking soda is that the pH is weakly alkaline, and its solubility in water is low compared to other inorganic alkaline detergents. The solubility in 100 g of water is 6.9 g at 15 ° C. and 15 ° C. 8.8 g, and 16.4 g at 60 ° C. (Source: Encyclopedia of Chemistry, Issued: Kyoritsu Publishing Co., Ltd., published in March 1964).
As described above, since the solubility of sodium bicarbonate in an aqueous solution is relatively low, it is possible to add sodium bicarbonate into the aqueous solution to form a slurry state. As for the average particle diameter of the baking soda used for the paste-form cleaning composition of this invention, about 50-350 micrometers is preferable. If the average particle diameter is less than the above range, the abrasiveness and fluidity may be reduced, and if it exceeds the above range, the slurry stability due to sedimentation may be reduced and the abrasiveness may be reduced. From such a viewpoint, the average particle diameter is more preferably 70 to 250 μm. The average particle diameter can be measured by a laser diffraction / scattering method, a sieve shaking method, or the like.

  Further, the content of baking soda in the paste detergent composition of the present invention is 50% by mass or more, preferably 55% by mass or more, considering the solubility of sodium bicarbonate in water, slurry formability, polishing action, etc. Considering the stability and fluidity of the slurry state, it is 85% by mass or less, and preferably 80% by mass or less. The paste-like detergent composition of the present invention using baking soda as a detergent component is effective for removing dirt from acidic soils and oil components containing fatty acids or fatty acid salts, considering its alkalinity and abrasiveness. It has a deodorizing effect that neutralizes the acidic odor.

(2) Antibacterial agent (A) The antibacterial agent used in the paste-like cleaning composition of the present invention is a gemini antibacterial agent (A) represented by the above formula and having two pyridinium salts in the molecule. (Compound name: 1,4-bis (3,3 ′-(1-decylpyridinium) methyloxy) butanedibromide (DPMBB)), contained in the paste-like detergent composition in an amount of 0.075% by mass or more. Has been.

Since baking soda does not have antibacterial properties, it has antibacterial properties against gram-negative bacteria, gram-positive bacteria, etc., which are classified based on the difference in cell walls when used and stored in detergent compositions containing sodium bicarbonate. It is desirable to provide a paste-like cleaning composition having both a cleaning effect and an antibacterial effect.
As described above, antibacterial agents can be classified into two types, inorganic antibacterial agents and organic antibacterial agents, and organic antibacterial agents are further classified into natural antibacterial agents and synthetic antibacterial agents. These organic antibacterial agents are known to exert antibacterial effects such as microbial biosynthesis inhibition, cell structure destruction, and biological material (DNA, RNA, etc.) damage.

  The antibacterial agent used in the paste-like cleaning composition of the present invention is excellent in solubility in an aqueous solution, has an excellent antibacterial effect even in a relatively small amount, and exhibits an excellent antibacterial effect in a short time. It is desirable to be able to do it. Inorganic antibacterial agents have dispersibility problems, and as mentioned above, organic natural antibacterial agents are difficult to expect high antibacterial properties, and organic synthetic antibacterial agents are mainly composed of baking soda as a cleaning agent. Until now, no paste-like cleaning composition that satisfies the above requirements has been known.

When the antibacterial agent (A) represented by the above formula, which is a pyridinium antibacterial agent, is contained as an antibacterial agent contained in the paste-like cleaning composition containing sodium bicarbonate as a main component of the cleaning agent, It was found that an excellent antibacterial effect can be exhibited in a short time even with a small amount.
The antibacterial agent (A) is less susceptible to environmental factors such as temperature dependence and coexisting substances, has excellent thermal stability, processability, no irritation, safety to human body, durability, etc. The antibacterial spectrum (range of sterilizable microorganisms) is excellent and non-irritating (see Non-Patent Document 1), so the paste-like cleaning composition of the present invention containing the antibacterial agent (A) is also this. Such an effect can be expected.

  The applicant has demonstrated the antibacterial effect of the antibacterial agent (A) sufficiently in an alkaline aqueous solution that is weaker than sodium sesquicarbonate as a cleaning agent component in the above application (Japanese Patent Application No. 2006-197157). Although it could not be found that the antibacterial agent (A) content in the paste-like cleaning composition is 0.075% by mass or more, the antibacterial effect is remarkably exhibited. I found it.

In addition, the following three kinds are known as anti-pyridinium-based antibacterial agents, but all of them are slightly soluble in water, so that the paste-like cleaning composition of the present invention is used as an antibacterial agent. Cannot be used.
(i) Cetylpyridinium chloride (also known as CPC)
(ii) 4,4 ′-(tetramethylenedicarbonyldiamino) bis (1-decylpyridinium bromide (also known as TMBDB)
(iii) N, N′-hexamethylenebis (4-carbonyl-1-decylpyridinium bromide) (also known as HBCDB)

The antibacterial agent (A) is a white crystalline powder, and its solubility in water is very high at 589 g / 100 g water at 20 ° C. According to Non-Patent Document 2, oral acute toxicity is LD50 of 300 mg / kg (rat), Mutagenicity is negative and skin sensitization is negative.
The content of the antibacterial agent (A) in the paste-like cleaning composition of the present invention is 0.075% by mass or more, preferably 0.15% by mass or more, and exhibits an excellent antibacterial effect. On the other hand, the upper limit of the content of the antibacterial agent (A) is not particularly limited from the antibacterial effect, but 1.0% by mass or less is preferable, and 0.75% by mass or less is more preferable in consideration of economy and the like. 0.40% by mass or less is more preferable.
Further, in a paste-like cleaning composition having a sodium bicarbonate content of 55 to 80% by mass and an antibacterial agent (A) content of 0.15 to 0.40% by mass, per milliliter (mL). E. coli and Staphylococcus aureus eradication rate in 5 minutes ([(initial viable count-viable count after 5 min) /) when the initial viable count is about 2 × 10 ⁺⁵ to 8 × 10 ⁺⁵ The initial viable count] × 100 (%)) can be 99% or more.

(3) Thickener or foaming agent In the paste-like detergent composition of the present invention, the paste-like detergent composition is more effectively prevented from dripping from an inclined surface or a vertical surface and has a cleaning effect. A thickener or a foaming agent can be included for the purpose of enhancing or the like. A thickener is an additive that works to increase the viscosity of the paste-like cleaning composition and prevent sagging and improve the cleaning effect. On the other hand, a foaming agent dissolves in a liquid and easily generates bubbles. It is a substance that keeps the generated foam stable and is generally distinguished from a so-called foaming agent (foaming agent) that foams by generating gas.

When the thickening agent or the foaming agent is contained in the paste-like cleaning composition of the present invention, the content is preferably 0.02 to 2.0% by mass in the composition. When the content of the thickener or foaming agent is 0.02% by mass or more, the necessary thickening or foaming properties are exhibited. On the other hand, even if the content exceeds 2.0% by mass, further thickening or foaming is achieved. The effect of improving the sex cannot be expected.
Since the thickener often has foaming properties, the examples of the thickener and the foaming agent are often the same. Therefore, as an additive having a thickener or a foaming agent, glycerin Fatty acid esters such as monoglyceride, polyglycerin fatty acid ester, and propylene glycol fatty acid ester, polysaccharides such as sodium carboxymethylcellulose (CMC), carrageenan, xanthan gum, guar gum, tamarind gum, pectin, locust bean gum, and modified starch .

(4) Paste detergent composition The paste detergent composition of the present invention is a mixture of sodium bicarbonate fine particles and antibacterial agent (A) fine particles, or a mixture of sodium bicarbonate fine particles containing antibacterial agent (A) fine particles in a predetermined ratio. It can obtain by mixing with water so that it may become the density | concentration of this, and fully stirring at the temperature of 70 degrees C or less in which decomposition | disassembly of sodium bicarbonate is accelerated | stimulated in aqueous solution.
As described above, the antibacterial agent (A) has a very high solubility in water, and the paste-like cleaning composition of the present invention has excellent antibacterial properties. It is understood that most antimicrobial agents (A) in the composition are dissolved on the aqueous phase side.

When sodium bicarbonate fine particles and antibacterial agent (A) fine particles are contained in the above-described proportion in the paste-like cleaning composition of the present invention, a slurry state can be formed, and separation into sodium bicarbonate and water during storage can be suppressed. However, when forming the paste-like cleaning composition, it is desirable to consider the total amount so as not to be stored for a long time. In addition, the paste-like cleaning composition of the present invention is preferably stored in a closed container at room temperature while avoiding direct sunlight.
If the paste-like detergent composition is left on the soiled area of the object to be cleaned, the baking soda dissolved in water exerts its cleaning action and the decomposition of the dirt proceeds. The particles can exert an abrasive action to make it easier to remove dirt.
The baking soda fine particles in the paste-like cleaning composition of the present invention have an excellent polishing action and the surface thereof is soft, so that it is possible to suppress the surface damage of the object to be cleaned and effectively remove the dirt. Therefore, it can be used for cleaning glass products, cutlery such as knives, forks and spoons, and silver products. In addition, since the paste-like cleaning composition of the present invention is in the form of a paste, since there is little dripping, it is suitable for cleaning wall surfaces such as walls and doors in consideration of adhesion, and is further used for baking on gas stoves. It can also be suitably used for cleaning complicated structures such as nets and virtues, and fine structures.

The paste-like cleaning composition of the present invention comprises (i) a sink, a kitchen counter, a microwave oven, a gas range, a glass top of an IH heater, a fish grill, a faucet, a drain outlet, etc., (ii) a frying pan, a pan , Dishes, (iii) range hood (ventilator), (iv) inside and outside cupboard, (v) toilet, (vi) toilet, (vii) bathroom, (viii) washing tub, (ix) under refrigerator (X) It is also useful for removing light dirt such as carpets and flooring.
The paste-like detergent composition of the present invention containing baking soda as a detergent component is expected to be used more and more in the future in consideration of the environment and safety. Moreover, according to the objective of washing | cleaning, organic acids, such as vinegar and a citric acid, soap, and essential oil can be mix | blended and used for this paste-form cleaning composition.
