Description

Bactericidal and antibacterial composition

The present invention relates to a disinfectant composition, an antibacterial agent composition, a liquid detergent composition, and a textile treatment agent composition.
This application is filed in Japanese Patent Application No. 2008-057847 filed in Japan on March 7, 2008, Japanese Patent Application No. 2009-029164 filed in Japan on February 10, 2009, and in Japan on February 10, 2009. Claimed priority based on Japanese Patent Application No. 2009-029165 filed and Japanese Patent Application No. 2009-029166 filed in Japan on Feb. 10, 2009, the contents of which are incorporated herein by reference.

As a disinfectant / antibacterial agent composition in the daily necessities field such as detergents, organic compounds mainly including quaternary ammonium salts have been mainly used. However, since organic compounds are less effective against gram-negative bacteria (such as E. coli), inorganic compounds have recently attracted attention. Inorganic compounds include those having photocatalytic activity, metal compounds containing metals such as silver, copper, and zinc (for example, silver sulfate and zinc sulfate) and complexes of metals and polydentate ligands (metal complexes) Etc. In particular, conventional metal complexes with metals having antibacterial and antibacterial effects tend to act on bacteria in very small amounts.
In recent years, due to the increase in cleanliness, the effects of washing textile products have been demanded not only for visible dirt removal, but also for cleaning (deodorizing) and deodorizing effects on odor stains. Yes. As one of the causes of odor generation from clothes after washing, it is known that dirt such as sebum remaining without being completely removed by washing is decomposed by microorganisms.

Specifically, examples of using a metal compound having a sterilization / antibacterial effect include sterilization / antibacterial containing a sterilization / antibacterial inorganic metal-containing component, and a cationic polymer and / or a basic polymer. A liquid composition has been proposed (see Patent Document 1).
In addition, as an example using a metal complex having antibacterial and antibacterial effects, at least one compound selected from the group consisting of hydrogen peroxide, hydrogen peroxide adduct of alkali metal atom carbonate and perborate, A composition containing a complex of a metal selected from the group consisting of Groups 3 to 12 of the periodic table and a polydentate ligand has been proposed (see Patent Document 2).
In Patent Documents 1 to 4, a method for obtaining a deodorizing effect by using an inorganic metal compound having sterilization and antibacterial properties to act on microorganisms such as microorganisms has been studied. And 6, a softener composition containing an inorganic metal compound having sterilization and antibacterial properties is proposed. As the inorganic metal compound, it is common to use a compound containing metals such as silver, copper, and zinc, or a complex (metal complex) of these metals with a polydentate ligand.
JP 2006-151907 A JP-A-9-132797 JP 2007-176985 A JP-A-3-141205 JP 2001-192967 A Japanese Patent Laid-Open No. 2001-200473

However, in the sterilization / antibacterial liquid composition proposed in Patent Document 1, the metal content of the inorganic metal-containing component having the sterilization / antibacterial effect is high, and particularly economical when silver is used. Problems arise.
In addition, the cationic polymer and / or the basic polymer in the sterilization / antibacterial liquid composition of Patent Document 1 are blended for the purpose of stably blending the inorganic metal-containing component so as not to cause coloring or sedimentation. It does not affect sterilization and antibacterial effects.
In addition, when an inorganic metal compound is mixed in a detergent for textile products, the detergent is diluted with a large amount of water during washing. Therefore, a large amount of inorganic metal is required to exhibit a sufficient sterilizing effect and antibacterial effect. It was necessary to add a compound, which was disadvantageous in terms of economy.
In addition, particularly in the case of a liquid cleaning agent, it is required to stably mix a cleaning agent component such as an inorganic metal compound in the liquid and maintain the storage stability of the cleaning agent.
However, simply adding an inorganic metal compound to the cleaning agent does not necessarily provide sufficient sterilization effect, antibacterial effect, and deodorization effect. Yes.

On the other hand, in Patent Document 2, a very small amount of a metal complex having a sterilizing and antibacterial effect is combined with a peroxide such as hydrogen peroxide or sodium percarbonate. Metal complexes with antibacterial and antibacterial effects show high antibacterial and antibacterial effects against gram-negative bacteria, but sterilize against gram-positive bacteria (such as Staphylococcus aureus) as opposed to the organic compounds mentioned above・ The antibacterial effect tends to be weak.
By the way, peroxides such as hydrogen peroxide and sodium percarbonate have improved sterilization and antibacterial effects when used in combination with metals. Therefore, in order to obtain a sterilization / antibacterial effect on both gram-negative and gram-positive bacteria, a method using a metal complex and a peroxide in combination is sometimes used.

However, when a metal complex and a peroxide are used in combination, the peroxide is decomposed by the metal complex, and the sterilization / antibacterial effect may be reduced. Therefore, in order to use a metal complex and a peroxide together and to act on bacteria more effectively as a disinfectant / antibacterial agent composition, a solid or liquid metal complex and a peroxide are mixed immediately before use. The mixture of metal complex and peroxide is not suitable for long-term storage.
Moreover, even when a metal complex and a peroxide are used in combination, the sterilization and antibacterial effects against Gram-positive bacteria are not always sufficient.

The present invention has been made in view of the above circumstances, and can exhibit excellent sterilization and antibacterial effects against both gram positive bacteria and gram negative bacteria with a small amount of metal without using a peroxide. Disinfectant / antibacterial composition, liquid detergent composition that can exhibit excellent sterilization effect or antibacterial effect while maintaining storage stability, and can exhibit excellent sterilization effect, antibacterial effect, and deodorization effect It aims at providing the processing agent composition for textiles.

As a result of intensive studies, the inventors of the present invention need to have an inorganic metal compound adsorbed on the textile after washing in order to obtain a deodorizing effect by utilizing the sterilization / antibacterial effect of the inorganic metal compound by washing. Focused on that. However, most of inorganic metal compounds in cleaning agents and treatment agents are easily washed away in the washing process such as rinsing, and simply by adding inorganic metal compounds in the cleaning agent or treatment agent, textile products after washing It was difficult for the inorganic metal compound to remain adsorbed. Therefore, as a result of examining the adsorption residual property of the inorganic metal compound, the present inventors have improved the adsorption residual property of the inorganic metal compound to the textile after washing by using a specific component together with the inorganic metal compound. The present inventors have found that this can be done and have completed the present invention.

n is any one of 1 to 3, and if n is within this range, a complex formed by the components (A1) and (B1), (A2) and (B2) or (A3) and (B3) Is considered to exist stably. Further, m is any one of 1 to 3, and if m is within this range, the complex is considered to exist more stably.

Of these, alkyliminodiacetate is preferred in view of the stability of the complex.

In the general formula (II), R ² is any one of an alkyl group having 8 to 22 carbon atoms and an acyl group having 8 to 22 carbon atoms. It is more preferable that the alkyl group and the acyl group have 12 to 18 carbon atoms. When the carbon number of the alkyl group or acyl group is 8 or more, the alkyl group tends to be adsorbed to the bacterium and the metal ion tends to come into contact with the bacterium. On the other hand, when the number of carbon atoms in the alkyl group or acyl group is 22 or less, there is no problem of solubility in water, and sterilization ability and antibacterial ability are maintained. In particular, when R ² is any one of an alkyl group having 12 to 18 carbon atoms and an acyl group having 12 to 18 carbon atoms, it is hydrophobic (that is, adsorptive to bacteria) and hydrophilic (that is, water) Since the balance with solubility is good, sterilization ability and antibacterial ability can be expressed more effectively.
Q is (NH— (CH ₂ ) _m ), where r is 1 or 0 (single bond). If r is 1 or less, it is considered that metal ions tend to come into contact with bacteria.
When r is 0 (single bond), A ² and A ³ may be the same or different and are selected from a hydrogen atom and a methyl group.
On the other hand, when r is 1, one of A ² and A ³ is a hydrogen atom, and the other is either a hydrogen atom or CH ₂ COOX ³ . At this time, X ³ is one selected from the group consisting of a hydrogen atom, an alkali metal atom, an alkaline earth metal atom, and a cationic ammonium group. Specific examples of the alkali metal atom, alkaline earth metal atom and cationic ammonium include the same as those in the general formula (I).
n is any one of 1 to 3, and if n is within this range, the complex is considered to exist stably.
m is any one of 1 to 3, and if m is within this range, the complex is considered to exist more stably.

The general formula (II) can be represented by the following general formula (II-1) and general formula (II-2). In addition, the symbol in each formula shows the same thing as said general formula (II).

In addition, the long-chain alkylamine compound represented by the general formula (II) and the long-chain alkylamine compound represented by the general formula (II) are more preferable than the long-chain alkylamine compound represented by the general formula (II). There exists a tendency for the disinfection effect and / or the antibacterial effect to be large. This is considered to be due to the following reason.
In the long-chain alkylamine compound represented by the general formula (I), the charge of the metal ion is reduced or canceled by the carboxyl group of the terminal group. On the other hand, in the long-chain alkylamine compound represented by the general formula (II), since the amino group interacts with the metal ion, the charge of the metal ion is maintained as it is. It is thought that it shows a higher effect on this.
As a result, the metal ions derived from the corresponding components (A1 to 3), each forming a complex with the components (B1 to 3), can be brought into contact with bacteria without distinction between Escherichia coli and Staphylococcus aureus. Even if it is a small amount, it can show a more excellent sterilization effect or antibacterial effect against both bacteria.

The component (B1) in the sterilization / antibacterial agent composition of the present invention is not particularly limited, but is blended so as to be 0.000001% by mass (0.01 ppm) or more in the sterilization / antibacterial agent composition. Is more preferably 0.000002% by mass or more, and particularly preferably 0.000003% by mass or more.
If the component (B1) is 0.000001% by mass or more in the sterilization / antibacterial agent composition, it is easy to form a complex with the component (A1), and the sterilization property and the antibacterial property are maintained.

The blending amount of the component (B1) in the sterilization / antibacterial agent composition is the molar ratio [B1] of the number of moles [B1] of the component (B1) and the number of moles of metal ions [M1] in the component (A1). ] / [M1]. At this time, [B1] / [M1] is preferably 1.0 to 50, preferably 1.5 to 45, based on the number of moles [M1] of metal ions in the component (A1) to be blended. Further preferred is 2.0 to 40, particularly preferred.

On the other hand, even if the component (B2-2) is added in an amount of more than 10% by mass, it is difficult to obtain an effect of improving the sterilization and antibacterial properties, which is economically disadvantageous.

The mass ratio of the component (A2) to the component (B2) in the liquid detergent composition is preferably (B2) component / (A2) component = 1.75 / 1 to 10/1. More preferably, it is / 1 to 10/1. When the mass ratio is less than 1.75 / 1, the ratio of the component (A2) present alone is increased without forming a complex with the component (B2) in the liquid detergent composition. As a result, the hydration state of the hydrophilic group of the component (C) described later is adversely affected (that is, the hydration water near the hydrophilic group is dehydrated, so that it is difficult to ensure the stability as a preparation). The storage stability of the cleaning composition tends to decrease. On the other hand, even if the mass ratio exceeds 10/1, it is difficult to obtain an effect of improving sterilization and antibacterial properties, which is economically disadvantageous.

Formulation of a long-chain alkylamine compound and / or an anion generated from the long-chain alkylamine compound (hereinafter, these may be referred to as “component (B3-2)”) in the treating composition for textile products. The amount is preferably 0.1 to 20% by mass, more preferably 0.2 to 17% by mass, and particularly preferably 0.4 to 14% by mass with respect to the total mass of the treating agent composition. When the blending amount of the component (B3-2) is 0.1% by mass or more, it is possible to impart sterilizing properties, antibacterial properties, and deodorizing properties to the clothes after washing. When the blending amount of the component (B3-2) is less than 0.1% by mass, the antibacterial effect particularly against S. aureus tends to be reduced. On the other hand, even if the component (B3-2) is added in an amount of more than 20% by mass, it is difficult to obtain a sterilization and antibacterial improvement effect commensurate with it, which is economically disadvantageous.

Moreover, the compounding quantity of (B3) component in a processing agent composition is the molar ratio [B3] of the number-of-moles [B3] of (B3) component, and the number-of-moles [M3] of the metal ion in (A3) component. / [M3] is preferable. At this time, [B3] / [M3] is preferably 0.1 to 50, preferably 0.15 to 45, based on the number of moles [M3] of metal ions in the component (A3) to be blended. More preferably, it is particularly preferably 0.2 to 40. If the blending amount of the component (B3) based on the number of moles of metal ions [M3] in the component (A3) is within the above range, the sterilization performance or antibacterial performance is remarkably improved, and the component (A3) Although mentioned later in detail, the complex stable with (D) component can form in a processing agent composition. In addition, a composition having good stability can be obtained.

In the sterilization / antibacterial agent composition of the present invention, the above-described (A1) component and (B1) component may be mixed to prepare a sterilization / antibacterial agent composition, or (A1) component and ( A disinfectant / antibacterial agent composition may be prepared by blending a complex formed with the component B1).
Moreover, although mentioned later in detail, when using the disinfection and antibacterial agent composition of this invention, a liquid detergent composition, and a processing agent composition as a liquid composition, (A1) and (B1) component, (A2) ) And (B2) component or (A3) and (B3) component are considered to form a complex.

In the processing agent composition for textile products, the component (A3) and the component (B3) described above may be individually mixed to prepare a processing agent composition, or the component (A3) and the component (B3) You may prepare a processing agent composition by mix | blending with the shape of the complex formed with a component.

As described above, by using together with the components (B1 to 3) corresponding to the components (A1 to 3), a sterilizing effect or antibacterial effect against both S. aureus and E. coli can be obtained. The combination of the component (A3) and the component (B3) is not particularly limited. However, in consideration of storage stability such as discoloration of the treatment agent composition, zinc sulfate or zinc chloride as the component (A3) and component (B3) A combination with alkyldiaminoethylglycidin is preferred.

In this way, the complex formed with the component (B1-3) corresponding to each of the components (A1-3) is blended, the disinfectant / antibacterial agent composition, the liquid detergent composition, the treatment for textile products If (B1-3) component corresponding to each of (A1-3) component in the agent composition forms a complex, (B1-3) component (A1-3) component corresponding to each It is possible to improve the adsorptivity of metal ions to clothing and fungi.

[Test 1: Preparation of disinfectant composition (1)]
<Examples 1 to 37, Comparative Examples 1 to 18>
Components (A1) and (B1) of the types shown in Tables 1 to 3 were added to water so as to have the concentrations shown in Tables 1 to 3, and sodium carbonate was added at a concentration of 0.106% by mass (10 mmol / L). It added so that it might become. Subsequently, the disinfectant composition (1) was obtained by adjusting the aqueous solution to pH 10.

Evaluation test of sterilization effect:
The sterilizing power was evaluated by a bacterial suspension method using Staphylococcus aureus and Escherichia coli.

(Staphylococcus aureus)
Staphylococcus aureus mother liquor (NBRC12732, institution name: Incorporated Administrative Agency National Institute of Technology and Evaluation, Biological Genetic Resources) prepared in 9.9 mL of the above-mentioned disinfectant composition (1) to have a bacterial count of 107 cells / mL 0.1 mL each was added and stirred uniformly to obtain a test solution.
After allowing the test solution to stand for 10 minutes, 1.0 mL of the test solution is collected and added to 9.0 mL of SCDLP medium (Wako Pure Chemical Industries, Soybean-Casein Digest Broth With Lectin & Polysorbate 80). It was. The operation of further diluting the obtained diluted solution 10 times was repeated 4 times to obtain 10 to 100000 times diluted solutions.
100 μL was collected from each of these dilutions, placed on a standard agar medium (manufactured by Akt), and evenly coated with a congeal rod and cultured in a thermostat at 37 ° C. for 1-2 days. Select those that can be counted, count the number of colonies, determine the number of viable bacteria, and determine the difference between the logarithmic value of the initial bacterial count (10 ⁷ cells / mL) and the logarithmic value of the viable bacterial count after the test, Evaluation was performed according to the following evaluation criteria. The results are shown in Tables 1-3.
Compared to the initial number of bacteria ×: Less than 1.0 digit of sterilization △: More than 1.0 digit to less than 1.5 digit ○: More than 1.5 digit of eradication, but not completely eradicated ◎: Number of remaining bacteria 0 (total annihilation)

(Escherichia coli)
Except for using S. aureus liquor (NBRC 3972, Institution: National Institute of Technology and Evaluation, Biological Genetic Resources Department) Thus, the number of E. coli bacteria was determined and evaluated according to the same evaluation criteria. The results are shown in Tables 1-3.

As shown in Tables 1 to 3, the disinfectant composition (1) obtained in Examples 1 to 37 is not only for Escherichia coli that is a Gram-negative bacterium, but also for Staphylococcus aureus that is a Gram-positive bacterium. Also shows a good sterilization effect.
In particular, Examples 2 to 5, 13 to 16 using Compound B1-2 to Compound B1-5 in which the alkyl group (R) has 12 to 18 carbon atoms in the above formula (1) as the component (B1) 26 to 29, the sterilization effect is high. This is considered to be because the balance between the hydrophobicity of the disinfectant composition (1) and the solubility in water is good. Further, as the component (B1), when the long chain alkylamine represented by the formula (I) is used (Examples 7, 18, and 31) and when the long chain alkylamine represented by the formula (II) is used ( When compared with Examples 8 to 11, 19 to 22, and 32 to 35), a higher sterilization effect tends to be obtained when the long-chain alkylamine represented by the formula (II) is used. This is because the complex is stable because there are multiple nitrogen atoms coordinated to the metal, and since the overall charge is neutral or higher, it is easy to adsorb to bacteria, and a higher sterilization effect is obtained. it is conceivable that.

In Comparative Examples 1 and 7 in which the component (B1) was not blended, a sterilizing effect on Escherichia coli was obtained, but a sterilizing effect on Staphylococcus aureus was low. In Comparative Example 13, no sterilizing effect was obtained for both S. aureus and E. coli.
In Comparative Examples 2, 8, and 14 where the component (A1) was not blended, the sterilization effect was not obtained, and the sterilization effect was not obtained for both S. aureus and E. coli.
In Comparative Examples 3, 9, and 15, iminodiacetic acid having no alkyl group at the terminal was used as the compound (B1), so that the sterilizing effect on Staphylococcus aureus was not obtained. In particular, Comparative Example 15 did not provide a sterilizing effect on E. coli.
In Comparative Examples 4, 10, and 16, since lauroyllysine that does not conform to the formulas (I) and (II) was used as the compound (B1), no sterilizing effect on S. aureus was obtained. In particular, Comparative Example 16 did not provide a sterilizing effect on E. coli.
In Comparative Examples 5, 11, and 17, lauroyl aspartic acid that does not match the formulas (I) and (II) was used as the compound (B1), and thus the sterilizing effect on S. aureus was low. In particular, Comparative Example 17 did not provide a sterilizing effect on E. coli.
In Comparative Examples 6, 12, and 18, since lauroyl sarcosine that does not match the formulas (I) and (II) was used as the compound (B1), the sterilizing effect on S. aureus was low. In particular, Comparative Example 18 was not able to obtain a sterilizing effect on E. coli.
Further, comparing the long chain acyl group basic amino acids of Comparative Examples 4-6, 10-12, 16-18 and Examples 9, 20, 33, the comparative example has an amide structure, compared to amine. Coordination power to metal is thought to weaken. In addition, it is thought that the effect of metal adsorption on bacteria is weakening from the viewpoint of charge. On the other hand, in the case of the example, it also has an amide structure, but has an amine structure at a relatively close distance to the amide structure. Therefore, it is presumed that the complex is stable due to the chelate effect.

[Test 2: Preparation of disinfectant composition (2)]
<Examples 38 to 50 and Comparative Examples 19 to 24>
(A1) component and (B1) component of the kind shown in Table 4 are added to water so that it may become the density | concentration shown in Table 4, and also sodium carbonate will be 0.130 mass% (12.3 mmol / L) density | concentration. Thus, hydrogen peroxide was added so that the concentration was 0.0065% by mass (1.91 mmol / L). Subsequently, the disinfectant composition (2) was obtained by adjusting the aqueous solution to pH 10.
About the obtained disinfectant composition (2), the disinfection effect evaluation test was performed in the same manner as the disinfectant composition (1). The results are shown in Table 4.

As shown in Table 4, the disinfectant composition (2) obtained in Examples 38 to 50 was used not only for Escherichia coli, which is a Gram-negative bacterium, but also for Staphylococcus aureus, which is a Gram-positive bacterium. It shows good sterilization effect.
In Comparative Example 19 in which the component (B1) was not blended, a sterilizing effect on Escherichia coli was obtained, but a sterilizing effect on Staphylococcus aureus was not obtained.
