Description

  The present invention relates to a deodorizing and antibacterial agent which is excellent in adsorptivity to deodorizing and antibacterial effects and as a result imparts a durable and deodorizing effect to houses, facilities and daily necessities.

Technical background

Conventionally, alkyltrimethylammonium chloride and 2-phenoxyethanol adduct are known as deodorants (for example, Patent Document 1).
JP-A-9-168717

  Compositions using these known deodorants can quickly resolve the odors that are currently floating, but they have low molecular weight malodors and animal-related odors that have permeated for many years. Off-flavors and microorganisms, especially deep odors caused by mold and actinomycetes, and off-flavors attached when building materials are burned out cannot be solved by conventional deodorants.

  The present inventor has paid attention to the above-mentioned problem and erases the off-flavor molecules remaining in the deep part by rationally adding an antibacterial agent having a deodorizing and bactericidal effect to a flexible material having penetrability and residual effect. The inventors have found that the prevention of adhesion of molecules can be imparted, and have reached the present invention.

  That is, the flexible substance of the present invention provides a deodorizing antibacterial agent characterized in that a known deodorant is blended with Jodomethyl-P-trisulfone which is a silicon resin (silicone) and has a deodorizing and sterilizing effect. is there.

  Since the deodorizing antibacterial agent of the present invention is effective for a long period of time compared to conventional deodorants by decomposing bad odors condensed in the deep part and preventing re-adsorption, regardless of the object, it is particularly public. Environmental cleansing is provided even in places where daily care is not possible, such as prevention of unpleasant odors and septic tank facilities.

  Hereinafter, the configuration of the present invention will be described in detail. The silicon resin used in the present invention has water repellency and flexibility and needs only to have a leveling effect, and is dissolved in 2-methyloxyethanol, ethanol and / or isopropyl alcohol, which is an organic solvent, Joodomethyl-P -A protective layer having air permeability is formed by the molecules of trisulfone, and deodorizing properties and deodorizing properties can be obtained simultaneously. It is possible to obtain a deodorizing antibacterial agent diluted and made aqueous with an alkyltrimethylammonium salt which is also effective as an emulsifier and a hydrophilic solvent ethanol and / or isopropyl alcohol.

  In the present invention, the essential deodorant antibacterial compound of silicon resin (silicone), alkyltrimethylammonium salt, 2-phenoxyethanol, and jodomethyl-P-trisulfone is 0.2 to less than 30% of the total weight, respectively, and water-based formulation Deodorant antibacterial agent composition in which the amount of ethanol or isopropyl alcohol is 50% by weight or more, and the deodorant antibacterial agent in which the dry component weight in the deodorant antibacterial agent composition is preferably 0.001 to 2% by weight .

  Silicone resin (silicone) is dissolved in an organic solvent and is water-repellent at room temperature with dimethylsilicone and polyoxyalkylene. The blending ratio in the essential deodorant antibacterial component is 0.5 to 20% by weight. In particular, the range of 2 to 10% by weight is preferable. When the blending ratio is less than 0.5%, the adsorptivity becomes dilute and the durability becomes poor, and when it exceeds 20% by weight, the air permeability of the protective layer may be impaired.

  Joodomethyl-P-trisulfone is known as an antibacterial agent, but is effective in promoting surface drying and eliminating low-molecular odors. It is a component that exhibits the deodorizing effect and breathability of essential components. The blending ratio of the jodomethyl-P-trisulfone in the essential deodorant antibacterial component is 0.2 to 10% by weight, preferably 0.5 to 5% by weight. If it is less than 0.2% by weight, the molecules relating to the air permeability of the protective layer are diluted. If it is 10% by weight or more, the adsorbability of the protective layer may be impaired.

  The blending ratio of the alkyltrimethylammonium salt in the essential deodorant antibacterial component is 1 to 25% by weight. When the amount is preferably 5 to 10% by weight and less than 1% by weight, the desired emulsifiability may be lost. If it exceeds 25% by weight, an irritating odor peculiar to the surfactant may be generated, which is not preferable.

  2-Phenoxyethanol is a component that acts as a solvent agent for the deodorizing antibacterial agent Jodomethyl-P-trisulfone, and exhibits a deodorizing action together with an essential deodorizing component. The blending ratio of the 2-phenoxyethanol in the essential deodorant antibacterial component is 1 to 30% by weight, preferably 5 to 10% by weight, and when it is less than 1% by weight, it does not act as a solvent. If it exceeds 30% by weight, the viscosity is amplified, the drying property is remarkably deteriorated, and the adsorptive property of the deodorizing effect is lost.

  Ethanol and / or isopropyl alcohol acts as a solvent for the silicon resin (silicone), jodomethyl-P-trisulfone, trimethylammonium salt, and 2-phenoxyethanol, and together with these essential components, deodorant and fragrance action together with deodorant components. It is a component shown. The blending ratio of the ethanol and / or isopropyl alcohol in the essential deodorant antibacterial component is 50% by weight or more, preferably 50 to 80% by weight.

  In the deodorant antibacterial agent composition of the present invention, in the deodorant antibacterial agent composition, in addition to the essential deodorant antibacterial component, for example, a low-toxic antifungal agent, siabendazole (TBZ), N-halomethylthio type ( Preventol A4-S) or the like can also be contained as an antibacterial auxiliary agent, and the blending ratio thereof is preferably 0.5 parts by weight or less with respect to 10 parts by weight of the essential deodorant antibacterial component.

  In order to use the deodorant antibacterial composition of the present invention as a deodorant antibacterial agent, water or ethanol and / or isopropyl alcohol is used so that the content of the essential deodorant antibacterial component is 0.05 to 25% by weight. It is preferred to dilute with the mixture. If the amount is less than 0.05% by weight, the desired deodorizing and antibacterial effect may not be obtained. If the amount exceeds 25% by weight, a deep low-molecular odor may be trapped, which is not preferable.

  In order to prepare a deodorant antibacterial agent using the deodorant antibacterial agent composition of the present invention, first, ethanol and / or isopropyl alcohol are mixed and stirred with other essential deodorant antibacterial components preferably in the above-mentioned blending ratio, and the deodorant antibacterial agent is prepared. It can be obtained by a method of obtaining components and then diluting with water or ethanol and / or isopropyl alcohol before use or at the time of use so that the content of the obtained deodorant antibacterial component is 0.05 to 25% by weight. .

The deodorant antibacterial agent composition of the present invention is suitable for the bad smell of complex pollution attached to toilet walls and floors, garbage and industrial waste facilities, vehicles, etc. and raw odors attached to biological containers such as fish. Effective, and then can prevent adhesion for a certain period of time. At this time, the portion intended for deodorization may be applied by spraying or brushing so as to be 50 to 100 ml per 1 m ² after dirt or the like is cleaned by ordinary cleaning, and is preferably used in two or more times.

The invention's effect

  The deodorant antibacterial agent composition of the present invention has a low molecular weight that is different from a spoiled odor by preventing the growth of microorganisms, in particular, the growth of Bacillus (Gram-positive gonococci) in addition to the initial deodorizing effect, and suppressing the production of ammonia Prevents the odor of the system and prevents the unpleasant odor common in public toilets for a long time. The adverse effects on people and other environments can be reduced to a minimum. Moreover, in the manufacturing method of this invention, the deodorizing antibacterial agent based on such a deodorizing antibacterial agent composition can be obtained easily.

50 parts by weight of ethanol, 20 parts by weight of isopropyl alcohol, 15 parts by weight of a monoalkyl ammonium salt, 7.5 parts by weight of 2-phenoxyethanol, 5 parts by weight of silicon resin (silicone) (KF96 manufactured by Shin-Etsu Chemical Co., Ltd.), Jodomethyl-P- A deodorizing and antibacterial component was prepared by mixing and stirring 2.5 parts by weight of trisulfone. Subsequently, the obtained deodorizing antibacterial component was diluted and mixed with 400 parts by weight of isopropyl alcohol. About the obtained deodorizing antibacterial agent, the following tests (a) to (b) were performed.
As for the evaluation of toilets, 5 supervisors and 10 followers were selected on the day of the test, and 10 men and women were allowed to enter and smell the scent.

(B) Chuo-ku, Tokyo of After the usual cleaning the public toilets of the underground mall, the deodorant antibacterial agent was sprayed separately 1m ² per 70ml to 2 times dry. The odor that could not be removed by normal cleaning was removed at the same time as the disappearance of the alcohol odor. After 10 days, 30 days, and 180 days later, the conventional odor is not generated and it is in a refreshing state.

  (B) In June in Shibuya-ku, Tokyo, 10 temporary toilets for refurbishment were spray-dried in two portions of 70 ml of the deodorizing antibacterial agent in the interior including the installation floor during temporary installation. There was no odor at the December inspection.

  The amount of water was changed by adjusting the deodorizing antibacterial agent in the same manner as in Example 1, except that the product TSF4440 (manufactured by Toshiba Silicone Co., Ltd.), which was adjusted to water-based silicon resin (silicone), was used. A deodorizing antibacterial agent was adjusted to 4,900 parts by weight, and tests (a) to (b) were conducted. The evaluation was performed by having each party actually smell the scent.

(I) The carpet used for 10 years by a Japanese cat male who survived for 21 years was a healthy body, and the odor during survival was sufficiently effective with the deodorant of (0002) above, but since 1 month before his death There was no effect on the disease odor.
After spraying 70 ml / 1 m ² of the deodorizing antibacterial agent according to the present invention on the carpet surface and drying it for 24 hours, the composite malodor disappeared and the carpet was regenerated.

(B) Because it is used in wooden public toilets under the Tokyo Metropolitan and Saitama prefectures, commercial deodorants and (0002) deodorizers have immediate effects, but rainy weather continues and stinks accumulate. Those that adhered to the wall or floor could not be deodorized.
As a result of applying the deodorizing antibacterial agent to a wooden wall surface or floor surface with a brush or a roller, odor adhesion was prevented even after 30 days.

Comparative Example 1

In Ibaraki Prefecture, the second floor of the three-story RC structure was damaged by a misfire. Due to the disappearance, a low molecular odor was burned onto the wall and ceiling slabs. After the whole was washed with water, the same deodorizing and antibacterial agent as in Example 1 was prepared in one chamber and spray-dried at 70 ml / 1 m ² . On the other hand, the same deodorizing antibacterial agent was spray-dried at 70 ml / 1 m ² except that Jodomethyl-P-trisulfone was not used in the other chamber. In the example using Joodomethyl-P-trisulfone after drying, there was no odor after 7 days. On the other hand, the room which was not used had a bad odor residue after drying.
