Description

Hard surface disinfectant composition and disinfectant article containing same {GERMICIDE COMPOSITION FOR HARD SURFACE AND GERMICIDAL ARTICLE HAVING THE SAME}

The present invention relates to a hard surface disinfectant composition and a sterilizing article comprising the same, and more particularly, to a disinfectant composition having excellent sterilizing power and a sterilizing article including the same while minimizing odor generated when using the sterilizing agent.

Many invisible microorganisms survive on the hard surface of living spaces such as living rooms, kitchens, toilets, and the like, and many pathogenic bacteria, including Escherichia coli and Staphylococcus aureus, are harmful. .

Accordingly, there is a growing awareness of the necessity of hygiene management of the residential environment, and sterilizing products including various kinds of disinfectant compositions are used.

In general, the disinfectant composition contains ethanol which is a sterilizing component, and the amount is added in a large amount of 60 to 70 wt% to maximize the sterilizing power. As the ethanol content ratio contained in the fungicide composition increases as described above, the sterilizing power is excellent, but the user has a disadvantage of feeling rejection by the strong and irritating odor peculiar to using ethanol.

In consideration of the problems of the prior art as described above, an object of the present invention is to provide a hard surface disinfectant composition excellent in sterilization power while minimizing the odor generated when using the disinfectant.

Another object of the present invention is to provide a hard surface sterilizing article comprising the sterilizing agent composition.

In order to achieve the above object, the present invention

Benzalkonium chloride (Benzalkonium Chloride) 0.01 to 0.1% by weight; And

90 to 95% by weight of purified water

It provides a hard surface disinfectant composition comprising a.

According to the present invention, it may be preferable that the fungicide composition further comprises 0.001 to 0.005 wt% of lactic acid.

The present invention also provides a sterilizing article for hard surface comprising the sterilizing agent composition in a liquid form or a wet wipe in the form of a fiber sheet.

Hereinafter, the present invention will be described in more detail.

In the course of studying the disinfectant composition suitable for the hard surface of the entire residential environment, the present inventors lowered the content of ethanol to minimize the ethanol odor generated during the use of the disinfectant, and added benzalkonium chloride together with the ethanol as a sterilizing component. When the ethanol or benzalkonium chloride to be used alone as compared to the case of using a sterilization synergism was confirmed to be excellent, to complete the present invention based on this.

Hard surface disinfectant composition according to the present invention is 5 to 10% by weight of ethanol; Benzalkonium chloride (Benzalkonium Chloride) 0.01 to 0.1% by weight; And 90 to 95% by weight of purified water.

Conventional fungicide composition is generally included in the content of 60 to 70% by weight of ethanol as a sterilization component to maximize the bactericidal power. As such, when the ethanol content included in the disinfectant composition is 60 to 70% by weight, the sterilization power is excellent, but there is a disadvantage in that the user feels rejection due to the strong and irritating odor unique to ethanol.

Therefore, the present invention has the advantage of minimizing the smell of ethanol generated when using the fungicide by lowering the content of ethanol contained in the fungicide composition to solve the above problems.

According to the present invention, the fungicide composition preferably comprises 5 to 10% by weight of ethanol. That is, in order to be able to exert its own antiseptic power while exhibiting the minimum bactericidal power required as a fungicide, the content of ethanol is preferably 5% by weight or more, and the content of ethanol is 10 weight in order to minimize the smell of ethanol generated when the fungicide is used. It is preferable that it is% or less.

In addition, the fungicide composition according to the present invention includes benzalkonium chloride (Benzalkonium Chloride). The benzalkonium chloride is a sterilization component added together with ethanol, and is a component added to prevent the lowering of sterilization power due to the decrease in the content of ethanol.

Compared to the case where the ethanol or benzalkonium chloride alone is prescribed alone, when mixed with ethanol and benzalkonium chloride as in the present invention it can exhibit excellent bactericidal power in a small amount due to the sterilization synergism between the two components.

At this time, the benzalkonium chloride is preferably contained in 0.01 to 0.1% by weight in the fungicide composition. That is, the content of benzalkonium chloride is preferably 0.01% by weight or more in order to exhibit a minimum sterilization synergy while preventing the reduction of sterilization power by reducing the ethanol content, and to prevent odor and foaming caused by excessive addition. The content of cornium chloride is preferably 0.1% by weight or less.

The fungicide composition according to the present invention includes the ethanol and benzalkonium chloride as a sterilizing component, and contains a residual amount of purified water. Preferably, the purified water may be included in 90 to 95% by weight.

In addition, the fungicide composition of the present invention may further include lactic acid which is a deodorant. At this time, the content of lactic acid may be determined in consideration of the deodorizing effect required in the composition, preferably may be included in 0.001 to 0.005% by weight.

On the other hand, the present invention provides a hard surface sterilizing article comprising the sterilizing agent composition.

The hard surface sterilizing article may include a sterilizing agent composition in a liquid form that is in the form of the composition itself. In addition, the sterilizing article may be in the form of a wet wipe (wet wipe) in which the sterilizing agent composition is impregnated into the fibrous sheet, the fibrous sheet may be applied to those conventional in the art to which the present invention belongs, such as pulp, nonwoven fabric It does not specifically limit a kind.

The hard surface sterilizing article includes a surface of furniture such as a desk, a chair, and a dining table; Surfaces of kitchen utensils such as cutting boards, knives, dining tables, and dish dryers; Surfaces of bathroom articles such as bathtubs and sinks; Surfaces of household appliances such as refrigerators, televisions, and computers; And it can be applied to the hard surface of the residential environment or public facilities where microorganisms such as the surface of various toys can survive.

The present invention provides a hard surface disinfectant composition and a sterilizing article including the same, while providing excellent disinfecting power while minimizing odor generated when using the disinfectant.
