JP5101135B2 - Antibacterial / deodorant composition and antibacterial / deodorant method using the same - Google Patents

Description

  The present invention relates to an antibacterial / deodorant composition and an antibacterial / deodorant method using the same.

In recent years, products that appeal to antibacterial have attracted a great deal of attention in accordance with the global epidemic of infectious diseases. On the other hand, with the increase in airtightness of houses and changes in consumers 'awareness of cleanliness, consumers' awareness of space odors is increasing.
In general, unpleasant odors in the home include a variety of odors such as toilet stool-derived urine odors, kitchen garbage odors, living room tobacco odors, entrance shoe odors, bedding fabric odors, consumer sweat and body odors, etc. These are all life odors that occur in normal life.
Many of these living odors involve microorganisms. For example, kitchen garbage odor is a rotting odor that causes microorganisms to propagate using food as a nutritional source and rot the food. One of the causes of the smell of the toilet space is the ammonia odor generated when microorganisms are propagated using the scattered urine as a nutrient source. Furthermore, the bad odor of the fabric product is one of the causes that the microorganisms decompose the sebum adhering to the fabric product to generate a medium chain aldehyde.

Conventionally, various deodorants and residential detergents have been proposed to eliminate such unpleasant odor components. Among them, physical methods and chemical methods have been proposed for odors that have already occurred.
Examples of physical methods include (Method 1) ventilation by opening and closing windows, forced ventilation by air conditioning equipment, and the like. In addition, (Method 2) an adsorbent that adsorbs and deodorizes unpleasant components by using an adsorbing power such as activated carbon, and a polymer water-soluble glucan having an α-1,4-glucoside bond represented by cyclodextrin A deodorant using contact force has been proposed (see, for example, Patent Document 1).

On the other hand, chemical methods include (Method 3) various chemical treatment methods such as fragrances and deodorants, and (Method 4) masking method.
(Method 3) is generally a method of deodorizing (chemically neutralizing or decomposing odor components) with acid, alkali, enzyme or the like. For example, Patent Document 2 discloses a technique for removing malodors such as toilets by containing a specific enzyme. Patent Document 3 discloses a deodorant composition that contains a metal silicate or aluminum-containing metal silicate as an active ingredient and is considered to deodorize due to a synergistic effect of oxidation / reduction reaction and adsorption action. .
(Method 4) is the most practiced method in general households, and deodorizes by masking unpleasant odors with the aroma of the deodorant itself.

In recent years, inorganic antibacterial agents have also attracted attention in recent years. The antibacterial action of silver is well known, and silver-containing components have been widely developed (see, for example, Patent Documents 4 to 5).
Japanese translation of PCT publication No. 2002-504837 Japanese National Patent Publication No. 11-504977 JP 63-220874 A JP-A-11-279453 JP-A-6-247817

  However, the proposals (methods 1 to 4) for eliminating the unpleasant odor so far have been only proposals for eliminating the odor. Further, the conventional inorganic antibacterial agents cannot sufficiently suppress the growth of microorganisms involved in the generation of odors that cause unpleasant odors, and the generation of unpleasant odors cannot be sufficiently suppressed.

Therefore, in the present invention, there is an antibacterial / disinfecting agent that has both a deodorizing effect for eliminating unpleasant odors and an antibacterial effect for suppressing the cause of unpleasant odors. It is an object to provide an odor composition.
Another object of the present invention is to provide an antibacterial / deodorant method capable of effectively antibacterial / deodorizing using the antibacterial / deodorant composition of the present invention.

The present invention has been completed. In other words, the following means are proposed.

The antibacterial / deodorant composition of the present invention comprises an antibacterial inorganic metal-containing component (A), a nitrogen-containing polymer (B), and a polymer water-soluble glucan or sugar alcohol having an α-1,4-glucoside bond ( And C).
In the antibacterial / deodorant composition of the present invention, the (B) may contain a basic polyamino acid.
Moreover, in the antibacterial and deodorant composition of the present invention, the (A) may contain at least one antibacterial inorganic metal selected from silver, copper, and zinc.

  In order to solve the above problems, the antibacterial / deodorant method of the present invention is the antibacterial / deodorant composition according to any one of the above, the maximum particle size of the antibacterial / deodorant composition particles immediately after spraying It sprays so that it may become 300 micrometers or less.

In the present invention, it is possible to provide an antibacterial / deodorant composition having both a deodorizing effect for eliminating an unpleasant odor and an antibacterial effect for suppressing the cause of unpleasant odor generation.
Moreover, the antibacterial and deodorizing method which can be effectively antibacterial and deodorized can be provided using the antibacterial and deodorant composition of the present invention.
