Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a germicidal detergent composition, and more particularly, to a germicidal detergent composition having both excellent germicidal power and detergency and having high safety for human body and environment.

[0002]

2. Description of the Related Art In general, foods such as vegetables and fruits are easily contaminated by pesticides and harmful microorganisms during the production process, resulting in rapid deterioration of quality and often causing food poisoning. In recent years, as a method for cleaning such foods, for example, a method using high-temperature water or a cleaning method using ozone water has been adopted. Had a problem of high cost. Further, in the method of using various LAS-based or higher alcohol-based cleaning agents that have been conventionally used as a chemical treatment method, residual cleaning agent components cannot be avoided on the object to be cleaned after cleaning, which is safe for the human body. It is a problem from the above. Furthermore, since these cleaning agents are intended only for removing stains, that is, for cleaning effects, and cannot be expected to have a sterilizing effect, there is a risk of causing food poisoning due to microbial contamination when vegetables such as salad are provided raw. It was From the viewpoint of safety to the human body as described above, consisting of only edible ingredients,
In addition, a neutral liquid detergent composition having a bactericidal effect is proposed in JP-A-7-188696. However, even such a detergent does not have sufficient antibacterial activity, and from the viewpoint of suppressing the growth of microorganisms after treatment in foods such as vegetables, a germicidal detergent having a stronger germicidal activity has been desired. . On the other hand, in the field of germicide, sodium hypochlorite is a germicide approved as a food additive and is generally used. However, when this is used as a bactericide solution, when the concentration in the aqueous solution is high, the tissues of vegetables and the like are deteriorated by chlorine, which not only deteriorates the texture and the taste. Further, when the concentration is low, the bactericidal effect tends to disappear in a short time because of the organic substances eluted from vegetables and the like. Further, since sodium hypochlorite is an unstable compound itself, it is easily decomposed with time, and the bactericidal effect is easily lowered even when mixed with an organic substance of a detergent. Therefore, when this is mixed with a cleaning liquid and used as a sterilizing cleaning liquid, it is necessary to confirm the effective chlorine concentration each time it is used and to remake the cleaning liquid, which causes a problem that the work is complicated. As described above, in the preparation of the sterilizing detergent, the cleaning power or the bactericidal power is insufficient only by simply combining the bactericidal component and the cleaning component, and the use of the additive or the like for the purpose of improving the performance is not possible. It may deteriorate the stability of the liquid. On the other hand, performing the cleaning and sterilization in separate steps complicates the work.

DISCLOSURE OF THE INVENTION The present inventors consider these various conditions and can effectively perform cleaning and sterilization at the same time, and have extremely high safety to human body and environment, and flavor of food. As a result of repeated studies aimed at developing a germicidal detergent that does not affect the
The present invention has been completed. That is, the present invention can safely and effectively sterilize and wash foods such as vegetables and fruits, tableware and the like without complicated work, and further, sterilization cleaner that does not affect the flavor of foods. It is intended to provide a composition.

[0004]

Means for Solving the Problems As a result of intensive studies to achieve the above-mentioned object, the present inventors have used polylysine as a bactericidal component, which is used as a chelating agent, a surfactant and a solubilizing agent. It has been found that the above objects can be effectively achieved by using a combination of germicidal detergent compositions. The present invention has been completed based on such findings. That is, the present invention provides a germicidal detergent composition comprising polylysine, a chelating agent, a surfactant and a solubilizing agent.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail. The present invention uses polylysine as a bactericidal component.
As polylysine, either α-polylysine or ε-polylysine can be used, but in the present invention, ε-polylysine can be preferably used from the viewpoint of safety. The above-mentioned polylysine is Streptomyces (streptom
It is a polypeptide obtained by culturing a microorganism of the genus yces) and formed by condensation of lysine, which is an essential amino acid for the human body. When this polylysine is hydrolyzed by an enzyme or the like in the body, it becomes L-lysine which is the original component, so that the safety is very high.
It is a bactericidal component that is significantly safer than conventional food preservatives, such as having a 0 value of 5 g / kg or more. As such a polylysine, either a free form or a form of a salt of an inorganic acid or an organic acid can be used, and it has been processed with an excipient or a bulking agent for easy handling. One can also be used. The above-mentioned polylysine is preferably blended in an amount of 0.01 to 10% by weight in the germicidal detergent composition of the present invention. If this amount is less than 0.01% by weight, a sufficient bactericidal effect cannot be obtained. On the other hand, if it exceeds 10% by weight, the effect is not significantly increased for the added amount, which is disadvantageous in terms of cost and tends to be poor in solubility. From this point of view, the blending amount is 0.2 to 8% by weight.
Is more preferable.

A chelating agent is blended with the above-mentioned polylysine in the germicidal detergent composition of the present invention. It is known that the chelating agent usually has the effect of enhancing the detergency of the surfactant by simultaneously blocking the metal ions in the cleaning liquid, and at the same time preventing the removal and redeposition of dirt. In the present invention, by using together with polylysine, a particularly excellent and powerful bactericidal effect is obtained as compared with the case of using each alone. As such a chelating agent, an organic acid type chelating agent is preferably used, and among these, ethylenediaminetetraacetic acid, citric acid, tartaric acid, malic acid, fumaric acid, succinic acid or salts thereof are preferably used from the viewpoint of bactericidal effect. . Examples of the salt of the organic acid include alkali metal salts such as sodium salt and potassium salt, amine salt, ammonium salt and the like. In the present invention, as the chelating agent, particularly as a food additive from the viewpoint of edibility. Disodium ethylenediamine tetraacetate (EDTA ・ 2Na ・
2H ₂ O) or citric acid, tartaric acid, malic acid or salts thereof are preferably used, and especially disodium ethylenediaminetetraacetate (EDTA · 2Na · 2H)
₂ O) is preferred.

The chelating agent is preferably contained in the germicidal detergent composition in an amount of 1 to 15% by weight. When the content is less than 1% by weight, no synergistic effect is observed in the bactericidal effect, and when it exceeds 15% by weight, the stability of the sterilization cleaning solution is deteriorated and the bactericidal effect cannot be sufficiently exhibited. EDTA ・ 2Na as a chelating agent
When 2H ₂ O is used, its amount is preferably in the range of 1: 1 to 1: 3 by weight ratio to polylysine. When the blending amount of EDTA.2Na.2H ₂ O deviates from the above range of the weight ratio, it may not be preferable for the same reason as described above regarding the blending amount of the chelating agent. In the present invention, the above chelating agents may be used alone or in combination of two or more.

In the present invention, the surfactant used together with the polylysine is used as a cleaning main component, but also has an effect as a bactericidal aid. Therefore, in the present invention, a surfactant having a bactericidal activity is preferably used. Examples of such surfactants include non-ionic surfactants such as monoglycerin fatty acid esters, sorbitan fatty acid esters, polyglycerin fatty acid esters, and sucrose fatty acid esters, or surfactants other than food additives. Although they can be used, monoglycerin fatty acid esters, polyglycerin fatty acid esters or sucrose fatty acid esters are preferably used from the viewpoints of edibility and safety to the human body or environment.

The above-mentioned surfactant is preferably blended in the germicidal detergent composition of the present invention in an amount of 0.05 to 60% by weight. If the blending amount is less than 0.05% by weight, the detergency may be insufficient, and if it exceeds 60% by weight, it may be insoluble in water and the stability of the liquid may be deteriorated. Further, from the viewpoint of efficiently performing both sterilization and washing, the blending amount is more preferably 1 to 50% by weight. That is, a sufficient bactericidal activity cannot be obtained by using the above surfactants alone or in a combination of a plurality thereof, but by adding the above amount to polylysine as in the present invention, an excellent bactericidal detergency which has not been conventionally predicted can be obtained. Can be demonstrated. In the present invention, such a surfactant can be used alone or in combination of two or more kinds.

The bactericidal detergent composition of the present invention contains a solubilizing agent in addition to the polylysine, the chelating agent and the surfactant. The solubilizer is used not only to solubilize the surfactant and maintain the stability of the liquid, but also as a cleaning component especially for oily soil. As such a solubilizing agent, any of those usually used as a solubilizing agent for a detergent can be used, but preferably, one selected from ethanol, glycerin and propylene glycol can be used. These solubilizers are
It is preferable to add 1 to 40% by weight of the germicidal detergent composition. If the blending amount is less than 1% by weight, the above effects cannot be sufficiently obtained, and if it exceeds 40% by weight, it is not desirable in terms of cost. From this point, the blending amount is 2 to
More preferably, it is 35 weight. In the present invention, the solubilizers may be used alone or in combination of two or more kinds.

The bactericidal detergent composition of the present invention contains a thickener, a fragrance,
Colorants and the like can be added. The thickener is added for the purpose of imparting a certain viscosity to the germicidal detergent composition depending on the application. That is, for example, when cleaning cooking utensils, tableware, etc., a cleaning agent is usually used directly on a sponge, but in order to adapt to such a case, it is necessary to give the sterilizing cleaning liquid a certain degree of viscosity. Because. As such a thickener, for example,
Gum arabic, dextran, pullulan, arabinogalactan, sodium CMC, xanthan gum and the like, sodium polyacrylate, sodium alginate, sodium caseinate and the like can be used, but the stability of viscosity and the stability of liquid (for example, precipitation occurs) ), Considering the change of antibacterial activity, gum arabic, dextran, pullulan, arabinogalactan or sodium caseinate is preferably used. Further, the above thickener may be influenced by its viscosity characteristics due to the coexistence of metal ions,
From this point of view, when the thickener is used, the above-mentioned chelating agent is preferably mixed. In consideration of the above points, the blending amount is appropriately determined depending on the use situation, but it is suitably in the range of 0.1 to 0.4 wt% in the germicidal detergent composition, for example.

As the fragrance and the coloring agent, any of those usually used as a cleaning agent can be used according to the purpose. The blending amount is not particularly limited, but it is usually preferably 0.2% by weight or less in the germicidal detergent composition from the viewpoint of odor transfer and color transfer to foods. The sterilizing detergent composition of the present invention is for suppressing adverse effects on foods,
Those in the neutral region, for example, in the pH region of 6.0 to 8.0 are preferable. Further, the amount to be used can be appropriately determined according to the purpose of use, and can be appropriately diluted and used.
