Description

LIQUID CLEANING AGENT, LIQUID BLEACHING COMPOSITION, AND DISINFECTANT COMPOSITION BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention is a liquid detergent, a liquid bleaching composition, and a bactericidal composition.

The present invention can be applied to the Japanese Patent Application No. 2011-236066 filed on October 27, 2011, the Japanese Patent Application No. 2011-246719 filed on November 10, 2011, and the Japanese Patent Application No. 2011-246720 , And Japanese Patent Application No. 2011-288718 filed on December 28, 2011, the contents of which are incorporated herein by reference.

Presence and proliferation of microorganisms may cause various abnormalities or infectious diseases, and measures have been demanded.

[0002] In recent years, various sanitizers in daily necessities such as medical cleaning agents and kitchen cleaning agents have become more hygienic, and in addition to eliminating the visible contamination, it is possible to sterilize microorganisms adhering to the objects to be cleaned . Examples of the bactericidal component used in the detergent include chlorine-based disinfectants such as sodium hypochlorite, oxygen-based disinfectants such as sodium percarbonate, sodium perborate and hydrogen peroxide, quaternary ammonium salts such as didecyldimethylammonium chloride and benzalkonium chloride.

The oxygen-based bactericide has a low sterilizing power, and when mixed with a liquid preparation, hydrogen peroxide is liable to be decomposed during storage and the formulation is limited.

Chlorine-based disinfectants and quaternary ammonium salts are liable to generate rust, and metal members are liable to corrode. In addition, when quaternary ammonium salt is used in combination with an anionic surfactant, there is a problem that the sterilizing power is remarkably lowered.

[0003] Conventionally, various cleaning agents in daily necessities such as medical cleaning agents and kitchen cleaning agents have been proposed that contain a sterilizing component other than an oxygen-series disinfectant, a chlorine-series disinfectant, and a quaternary ammonium salt.

For example, there has been proposed a antibacterial / antimicrobial composition containing a mixture or complex of a specific water-soluble metal salt and a specific long-chain alkylamine (for example, Patent Document 1).

Alternatively, a bactericide containing N, N-bis (3-aminopropyl) octylamine has been proposed (for example, Patent Document 2).

In addition, a liquid detergent used for washing of medical supplies (articles) is required to have a high cleaning power against contamination adhered to a substrate. For example, among medical cleaning agents, there is an enzyme mixed with a surfactant to further increase the washing power.

Further, in order to impart antibacterial property or antimicrobial property to laundry after washing, there is an inorganic metal compound, long chain amine and the like mixed. For example, a liquid detergent containing a water-soluble metal salt of zinc, copper or silver, a polyethyleneimine or a specific long-chain alkylamine compound (hereinafter referred to as "amine compound") and a surfactant has been disclosed (see Patent Document 3) . These amine compounds and the like are used for improving the adsorption residue of the water-soluble metal salt on the substrate.

On the other hand, in the field of detergents, there is a demand for reducing the amount of the cleaning agent used per washing, reducing the size of the container in which the cleaning agent is accommodated, and reducing the amount of resin waste.

To such a demand, a so-called " thickening type " composition containing a surfactant at a high concentration as a composition of a liquid detergent has been developed.

The liquid detergent is generally mixed with an anionic surfactant for the purpose of improving detergency against protein contamination adhered to a subject (subject) to be cleaned such as medical care or preventing re-contamination during cleaning.

Some of the liquid detergents include cationic surfactants and cationic bases such as long-chain amines in order to impart flexibility to laundry after washing or to impart antibacterial properties.

For example, a polyoxyalkylene alkyl ether, a specific tertiary amine compound or a salt thereof as a cationic base, and an SO ₃ group or a SO ₄ group are added to the polyoxyalkylene alkyl ether for the purpose of improving the detergency, , And a medical liquid detergent containing a specific solvent have been proposed (see Patent Document 4).

In addition, a bleaching composition (bleaching detergent, bleaching agent, etc.) in which a substance having a bleaching effect (bleaching component) is blended is generally used for a washing treatment or a bleaching treatment of a textile product such as a medical treatment. The bleaching composition is in the liquid state in view of simplicity such as being easy to be pulverized and able to be directly applied to medical treatment with contamination, and the like. Further, since the oxygen-based bleaching composition containing hydrogen peroxide as a bleaching component can be used for a wide range of medical applications including not only white but also color pattern (color pattern), it is possible to use an oxygen- Consumers are also using laundry.

The liquid type bleaching composition is intended to be used not only to remove waterborne stain stains adhering to the object to be cleaned but also to eliminate oily stain stains (dirty stains, sebum stains, etc.).

For example, a liquid bleaching composition containing hydrogen peroxide, a water-soluble polymer having a specific repeating unit, and a surfactant has been proposed for the purpose of removing hydrophobic contaminants such as sebum contamination (see Patent Document 5).

Patent Document 1: International Publication No. 2009/110590 Patent Document 2: Japanese Patent Specification No. 2003-503321 Patent Document 3: JP-A-2010-184987 Patent Document 4: Japanese Patent Application Laid-Open No. 2011-42766 Patent Document 5: JP-A-2005-187695

However, in the techniques of Patent Documents 1 and 2, a sterilizing power still satisfactory was not obtained.

Therefore, one aspect of the present invention aims to provide a bactericidal composition which can inhibit corrosion of metal members and is excellent in sterilizing power.

Further, in the liquid cleaning agent of the concentrated type, since the surfactant is contained in a large amount, the content of water is smaller than that of the ordinary composition. As a result, in the case of the concentration type composition, the solubility of the enzyme tends to deteriorate. In addition, when an amine compound or the like is contained as in the invention of Patent Document 3, there is a problem that it is difficult to secure the appearance stability (transparency and fluidity) of the composition.

Further, in the invention of Patent Document 3, a water-soluble metal salt is used. Generally, it is difficult to ensure the appearance stability of a liquid composition containing a water-soluble metal salt. In addition, in the case of an amine compound or the like which is used in combination with a water-soluble metal salt, the effect of imparting bactericidal properties to a substrate is insufficient.

Another object of the present invention is to provide a liquid detergent excellent in both the effect of imparting bactericidal property to a substrate and the external appearance stability in a concentrated type composition containing a high concentration of a surfactant.

Further, in the liquid detergent using the anionic surfactant and the cationic base agent in combination, such as the invention of Patent Document 4, the effect of imparting antimicrobial properties to the substrate is low. This is considered to be because the cationic base is affected by the negative surfactant and its cationic property is reduced.

On the other hand, if washing is repeatedly carried out using a liquid detergent containing a cationic base agent, there is a problem that yellowing gradually occurs due to the kind of the subject matter. It is effective to use an anionic surfactant in combination with this problem. However, as described above, the cationic property of the cationic base agent is liable to be reduced by the combined use of an anionic surfactant.

Therefore, another aspect of the present invention is to provide a liquid detergent which is superior in both flexibility and antimicrobial effect to a substrate and inhibits the occurrence of yellowing of the substrate even when an anionic surfactant is contained therein And the like.

In addition, the oxygen-based bleaching composition such as the invention of Patent Document 5 exerts a high decontamination effect on water-based stain contamination by the combination of hydrogen peroxide. However, the removal effect on the oil-based stain contamination is not satisfactory, and the effect of removing the oil-based stain such as the colander is inadequate.

Therefore, another aspect of the present invention is to provide a liquid bleaching composition excellent in the effect of removing oil contamination on a substrate.

As a result of intensive studies, the inventors of the present invention have found that, by using a specific N, N-bis (3-aminoalkyl) alkylamine and a specific metal in combination, a composition that does not cause metal corrosion and has improved sterilizing power can be obtained , Which led to the present invention.

(Bactericidal composition)

First, a description will be given of a bactericidal composition as a first embodiment of the present invention.

A bactericidal composition as a first embodiment of the present invention is a composition comprising a component (A1): N, N-bis (3-aminoalkyl) alkylamine and a component (B1): silver Or more.

The term " bactericidal composition " means any composition that achieves a germicidal effect on a substance to be treated. That is, in the bactericidal composition according to the first embodiment of the present invention, the "bactericidal effect" means that the number of viable bacteria in gram-positive bacteria or gram-negative bacteria is reduced to 1/10 or less when the concentration of the bactericidal composition is 0.001 to 100% it means.

The formulation of the bactericidal composition of the first embodiment of the present invention may be a liquid obtained by dissolving each component of the bactericidal composition of the present invention in purified water or may be prepared by dissolving each component of the bactericidal composition of the present invention in a granular tablet, Or a bar-shaped solid. Of these, a liquid is preferable from the viewpoint of convenience when applied directly to the object to be treated or diluted with water or the like.

In the case of a liquid bactericidal composition (hereinafter sometimes referred to as a " liquid bactericidal composition "), one-component type in which the components (A1) and (B1) are mixed together in a dispersion medium may be used. Liquid type comprising a liquid and a second liquid containing the component (B1). That is, the one-liquid type means that the component (A1) and the component (B1) are dispersed together in water as a dispersion medium. On the other hand, the two-part type is a method in which a component (B1) (second liquid) dispersed in water is dispersed in a proportion of 10: 1 to 1: 100 in a mass ratio to the component (A1) It may be provided as a kit or a package in which the first liquid and the second liquid are individually packaged individually.

In the case of a solid bactericidal composition (hereinafter sometimes referred to as a "solid bactericidal composition"), the components (A1) and (B1) may be mixed and the components (A1) and (B1) May be prepared.

When the bactericidal composition according to the first embodiment of the present invention is a liquid bactericidal composition, the viscosity of the liquid bactericidal composition is not particularly limited and is, for example, 10 to 300 mPa · s, S. If the viscosity of the liquid disinfecting composition is 10 to 100 mPa · s, it is preferable because discharge from the container is easy. The viscosity of the liquid disinfecting composition shows a value (measurement condition: rotor No. 2, rotation number 30 rpm, viscosity after 10 rotations) measured by a B-type viscometer (manufactured by TOKIMEC).

The pH of the liquid disinfecting composition can be determined in view of the formulation. The pH of the concentrated liquid type bactericidal composition to be used as a diluted treatment liquid injected into water is preferably 4 to 12, more preferably 5 to 11, and more preferably 7 to 11, for example. If the pH is less than the lower limit, that is, the pH is lower than 4, the pH of the treatment liquid may be lowered and the sterilizing power may be lowered. If it exceeds the upper limit value, that is, the pH exceeds 12, there is a possibility that a precipitate is formed during storage. If the pH of the concentrated liquid type bactericidal composition is 4 to 12, it is preferable that the sterilizing power is not lowered and no precipitate is formed during preservation of the liquid bactericidal composition.

Further, in the case of a straight-type liquid disinfecting composition used without dilution with water, a pH of 4 to 12 is preferable, a pH of 5 to 11 is more preferable, a pH of 7 to 11 is more preferable, a pH of 8 to 10 is more preferable , And a pH of 9 to 10 is particularly preferable. If the pH is below the lower limit, that is, below pH 4, the sterilizing power may deteriorate or the anticorrosion may deteriorate. If the pH is above the upper limit, that is, above 12, the sterilizing power may decrease. If the pH of the straight-type liquid bactericidal composition is 4 to 12, it is preferable since the sterilizing power and the anti-corrosiveness are not lowered. The pH (25 캜) of the bactericidal composition shows a value measured in accordance with JIS (Japanese Industrial Standard) K3362-1998 using a pH meter (Horiba F-22, manufactured by Horiba K.K.).

≪ Component (A1) >

In the first embodiment of the present invention, the component (A1) is an N, N-bis (3-aminoalkyl) alkylamine represented by the following general formula (I) The microbicidal composition according to the first embodiment of the present invention can exhibit sterilizing power while suppressing corrosion of the metal member (anticorrosive) by containing the component (A1).

R ¹ -N [(CH ₂ ) _n -NH ₂ ] ₂ ... (I)

[Wherein R ¹ represents an alkyl group having 8 to 18 carbon atoms and n is an integer of 1 to 4]

In the above general formula (I), R ¹ may be straight-chain or branched, of which straight-chain is preferable. If R < ^{1 >} is a straight chain, the sterilizing ability of the bactericidal composition can be further increased.

The carbon number of R ¹ is 8 to 18, preferably 8 to 14, and more preferably 12. When the carbon number is less than 8, the sterilizing power is lowered. When the carbon number is more than 18, the solubility in water is lowered. When the carbon number of R ¹ is 8 to 18, it is preferable because the sterilizing power and the solubility in water are not lowered.

In the general formula (I), n is an integer of 1 to 4, of which 2 to 4 is preferable, and 3 is more preferable. Within this range, that is, when n is an integer of 1 to 4, a good sterilizing power can be exerted.

Examples of such component (A1) include N, N-bis (3-aminomethyl) dodecylamine, N, N, N-bis (3-aminomethyl) alkylamine; N, N-bis (3-aminoethyl) dodecylamine such as N, N-bis (3-aminoethyl) octylamine, N, 3-aminoethyl) alkylamine; N, N-bis (3-aminopropyl) dicyclohexylcarbodiimide such as N, N-bis (3-aminopropyl) octylamine, N, 3-aminopropyl) alkylamine; N, N-bis (3-aminobutyl) dodecylamine such as N, N-bis (3-aminobutyl) octylamine, N, 3-aminobutyl) alkylamine and the like. Among them, N, N-bis (3-aminopropyl) alkylamine is preferable from the viewpoint of exerting an excellent germicidal effect in a wide pH range, N, N-bis (3-aminopropyl) dodecylamine is more preferable.

The content of the component (A1) in the bactericidal composition as the first embodiment of the present invention can be determined in consideration of the formulation of the bactericidal composition and the like. For example, the content of the component (A1) in the concentrated liquid type bactericidal composition to be added to water and diluted is preferably 0.01 to 10% by mass, more preferably 0.1 to 10% by mass based on the total mass of the concentrated liquid type bactericidal composition, More preferably 3% by mass, and still more preferably 0.3% by mass to 3% by mass. If the content of the component (A1) is less than the lower limit, that is, if the content is less than 0.01% by mass based on the total mass of the concentrated liquid type bactericidal composition, the sterilizing power may be insufficient. , That is, with respect to the total mass of the concentrated liquid fungicidal composition, if it exceeds 10% by mass, the liquid stability may be impaired. If the content of the component (A1) in the liquid fungicidal composition is 0.01 to 10 mass%, it is preferable since it has sufficient sterilizing power and the liquid stability of the liquid bactericidal composition is not impaired. Alternatively, the content of the component (A1) in the straight-type liquid bactericidal composition to be used without dilution with water is preferably 0.1 mass ppm or more, more preferably 0.5 mass ppm or more with respect to the total mass of the straight- More preferably 1 mass ppm or more, and still more preferably 3 mass ppm or more. The greater the content of the component (A1), the better the sterilizing power against a wide range of microorganisms. For example, for Escherichia coli highly susceptible, when the content of the component (A1) is 0.1 mass ppm or more relative to the total mass of the liquid bactericidal composition, a sufficient sterilizing power is exerted. For staphylococci with low susceptibility, ) Component is 3 mass ppm or more with respect to the total mass of the liquid bactericidal composition, sufficient sterilizing power can be exerted.

The upper limit of the content of the component (A1) in the straight-type liquid bactericidal composition is not particularly limited, and it is preferably 10000 mass ppm or less, more preferably 1000 mass ppm or less with respect to the total mass of the liquid bactericidal composition More preferably 300 mass ppm or less, and further preferably 100 mass ppm or less. That is, the content of the component (A1) in the straight-type liquid bactericidal composition is preferably 0.1 to 10000 ppm by mass, more preferably 0.1 to 1000 ppm by mass, and still more preferably 0.5 to 300 ppm by mass with respect to the total mass of the liquid bactericidal composition Is particularly preferable.

Thus, even if the content of the component (A1) is at least 0.1, that is, the content of the component (A1) in the straight-type liquid bactericidal composition is 0.1 mass ppm relative to the total mass of the liquid bactericidal composition, The fungicidal composition can exert a good sterilizing power.

For example, the content of the component (A1) in the solid bactericidal composition is preferably 0.01 to 10% by mass, more preferably 0.1 to 3% by mass, more preferably 0.3 to 3% by mass based on the total mass of the solid bactericidal composition % Is more preferable. When the content of the component (A1) is less than the lower limit, that is, when the content of the component (A1) is less than 0.01% by mass with respect to the total mass of the solid bactericidal composition, the sterilizing power may become insufficient. , And if it is more than 10% by mass, the form stability of the solid fungicidal composition may be impaired. When the content of the component (A1) is 0.01 to 10 mass% with respect to the total mass of the solid fungicidal composition, it is preferable since it has sufficient sterilizing power and does not impair the shape stability of the solid fungicidal composition.

≪ Component (B1) >

In the first embodiment of the present invention, the component (B1) is at least one selected from the group consisting of silver, zinc and copper. In the first embodiment of the present invention, the bactericidal composition contains the component (B1), so that the anticorrosion property against the metal member can be enhanced and the sterilizing power of the component (A1) can be increased.

As the component (B1), zinc is preferable. Silver may cause the object to be blackened, and copper may discolor the object to be treated. In addition, because the anticorrosion is in the tendency of zinc> copper ≥ silver. That is, the relationship between the corrosion resistance of these metals is that zinc has a higher anticorrosion property than copper and silver, and copper has anticorrosion property of less than zinc and silver. Therefore, if the component (B1) is zinc, it is preferable since the treated product does not discolor and the antimicrobial property of the bactericidal composition to the metal member becomes high.

The component (B1) may be blended with various bactericidal compounds, that is, various metal salts in the bactericidal composition.

The metal compound of the component (B1), that is, the metal salt is not particularly limited as long as it dissolves in water. Examples thereof include nitrates, sulfates, chlorides, perchloric acid and water, inorganic salts such as ammonium chloride salts and cyanides, And water-soluble metal salts such as organic salts such as tartrate salts and glycine salts.

However, if the first treatment liquid is brought into contact with the object to be treated after bringing the second treatment liquid into contact with the treatment target, the sterilizing power may be lowered. Therefore, when the first treatment liquid and the second treatment liquid are used, it is preferable that the first treatment liquid is brought into contact with the object to be treated, and then the second treatment liquid is brought into contact with the object to be treated.

That is, when the object to be treated is sterilized by immersing the object in a concentrated liquid fungicidal composition or a treatment liquid of the solid fungicidal composition, the liquid fungicidal composition of the present invention, or the method of sterilization using the solid fungicidal composition, It is preferable to have the steps (1F) to (1K).

The concentration of the bactericidal composition in the treatment liquid can be determined depending on the contents of the components (A1) and (B1) in the bactericidal composition. For example, the content of the component (A1) in the treatment liquid is preferably 0.1 mass ppm or more, more preferably 0.5 mass ppm or more, more preferably 1 mass ppm or more, and most preferably 3 mass ppm or more, More preferably, the mass ppm or more is more preferable. The greater the content of the component (A1) in the treatment liquid, the better the microbicide can exhibit a good sterilizing power. For example, for Escherichia coli highly susceptible, if the content of the component (A1) in the treatment liquid is 0.1 mass ppm relative to the total mass of the treatment liquid, the microbicide sufficiently exhibits sterilizing power, and for Staphylococcus aureus having low susceptibility, The content of the component (A1) in the treating liquid is 3 mass ppm or more relative to the total mass of the treating liquid. The upper limit of the content of the component (A1) in the treatment liquid is not particularly limited, and is preferably, for example, 1000 mass ppm or less, more preferably 100 mass ppm or less, further preferably 30 mass ppm or less, More preferably 8 mass ppm or less.

The content of the component (B1) in the treatment liquid is preferably 0.01 mass ppm or more, more preferably 0.069 mass ppm or more, further preferably 0.1 mass ppm or more, and 0.5 mass ppm or less Or more, more preferably 0.69 mass ppm or more. The reason for this is that sufficient sterilization effect can be obtained when the amount is not less than the above lower limit, that is, 0.01 mass ppm or more with respect to the total mass of the treatment liquid. The upper limit of the content of the component (B1) in the treatment liquid is not particularly limited. For example, it is preferably 1000 mass ppm or less, more preferably 100 mass ppm or less, and further preferably 8 mass ppm or less. In the method of disinfecting the object to be treated using the liquid type bactericidal composition or the solid fungicidal composition of the present invention, the method of adjusting the processing liquid in the step (1F) is preferably a method in which the component (A1) , It is preferable to dissolve the bactericidal composition in water to such a concentration range.

If the molar concentration of the component (A1) in the treatment liquid is less than 0.3 mol / l, the sterilizing power may be lowered. If the molar concentration of the component (A1) If it exceeds 10 mmol / l, the sterilizing power is saturated. When the molar concentration of the component (A1) is from 10 mu mol / l to 1 mmol / l with respect to 1 l of the treatment liquid, the sterilizing power is not lowered or saturation is preferable.

The molar concentration of the component (B1) in the treatment liquid is preferably, for example, 30 n mol / l to 10 mmol / l, and more preferably 2.3 μ mol / l to 100 μ mol / l. When the molar concentration of the component (B1) in the treatment liquid is more than 10 mmol / l, the precipitate tends to be easily generated. It is because. When the molar concentration of the component (B1) in the treatment liquid is 30 nmol / L to 10 mmol / L, the sterilizing power is not lowered and precipitates are less likely to be formed, which is preferable.

In the method of disinfecting the object to be treated using the liquid type bactericidal composition or the solid fungicidal composition of the present invention, the method of adjusting the processing liquid in the step (1F) is preferably a method in which the component (A1) , It is preferable that the bactericidal composition is dissolved in water so as to have the molar concentration.

If the pH of the treatment liquid is lower than the lower limit value, that is, lower than the lower limit value, the sterilizing power may deteriorate or the anticorrosiveness may deteriorate. If the pH is above the upper limit value, that is, above 12, the sterilizing power may decrease. If the pH of the treatment liquid is 4 to 12, it is preferable since the sterilizing power and the anticorrosion property are not lowered. The pH of the treatment liquid can be adjusted using a pH adjuster.
