Description

[Detailed description of the invention]

The present invention relates to a granular deodorizer, particularly a granular deodorizer to be added to the dust collection bag of a vacuum cleaner, and more particularly, to a granular deodorizer that is used to prevent the growth of fungi in the dust collection bag of a vacuum cleaner. , relates to a granular deodorizer that gives a refreshing feeling to a room after cleaning by imparting a fragrance to the emitted exhaust gas. Generally, when cleaning is performed using a suction type vacuum cleaner such as a vacuum cleaner, the sucked air always passes through a dust collection bag inside the vacuum cleaner and is released into the atmosphere. The garbage, dust, and dirt (collectively referred to as dust) that must be cleaned often have a foul or unusual odor, and these dusts may also have microorganisms such as bacteria attached to them. This can often be the source of odors. Therefore, the person cleaning the room must be troubled by the bad odor that accompanies this exhaust gas, and especially when cleaning is done in rainy weather or in winter, such odor tends to fill the room after cleaning. In general, as air fresheners or deodorants, there are widely used ones that contain a fragrance using an aqueous gel such as gelatin or carrageenan as a carrier, or those that contain a fragrance in a carrier made of a sublimable solid and are formed into tablets. It is used. However, such fragrances tend to be sticky in nature, and when added to the bag, they adhere to the walls of the bag, causing problems such as clogging. Another disadvantage is that the effective period during which the fragrance can be released into the room is short, and therefore the fragrance is lost before the dust collection bag becomes full of dust. The present inventor has discovered that when α-bromosinnamic aldehyde, which is a sublimable antifungal agent and antibacterial agent, and fragrance are both supported on a granular solid adsorbent, α-bromosinnamic aldehyde alone can be supported on the granular solid adsorbent. It has been found that extremely superior antifungal and antibacterial effects and superior deodorizing effects can be obtained compared to other products. According to the invention, a granular solid adsorbent having a pore volume of 0.2 to 0.9 cc/g and a particle size of 2 to 10 mm is provided with 0.3 to 10% by weight of α-bromosinnamic aldehyde and 2 to 10% by weight per adsorbent. A granular deodorant characterized in that it carries 30% by weight of fragrance. The α-bromosinnamic aldehyde used in the present invention has the following formula: Sublimable powder (melting point
71.5-72℃), and the vapor is a substance that prevents the growth and growth of mold, etc. An important feature of the present invention is that when α-bromocinnamic aldehyde is dissolved in a fragrance and supported on a granular solid adsorbent, α-cinnamic aldehyde alone is supported as shown in the example below. It achieves a significantly superior antibacterial effect and an overall superior deodorizing effect.
The exact reason for this is unclear, but the generation of α-bromocinnamic aldehyde vapor from the adsorbent is promoted in the form of a fragrance solution compared to the case of α-bromocinnamic aldehyde alone. It seems that this is for a reason. In the present invention, α-bromocinnamic aldehyde is present in an amount of 0.3 to 10% by weight, in particular 0.5% by weight, based on the adsorbent.
The optimum combination of fragrance and antibacterial properties is obtained when the fragrance is adsorbed in an amount of 2 to 2% by weight, and the fragrance is adsorbed in an amount of 2 to 30%, especially 7 to 15% by weight per adsorbent. α-Bromosinnamic aldehyde is easily dissolved by simply adding it to a liquid fragrance and stirring at room temperature or with heating if necessary, resulting in a transparent solution. By impregnating a granular solid adsorbent with this, The desired granular deodorant is obtained. The fragrances used in the present invention include, but are not limited to, natural or synthetic fragrances such as camphor oil, cassia oil, boisterous oil, canola oil, eucalyptus oil, cedar oil, sandalwood oil,
Rhubarb oil, ylang ylang oil, lemon oil,
Essential oils such as orange oil, bergamot oil, lavender oil, patch lily oil, citronella oil, lemongrass oil, vetiva oil, rose oil, geranium oil, animal fragrances such as musk, civet, sea oval scent, ambergris, vanillin, methyl salicylate , cinnamyl aldehyde, β-phenylethyl alcohol, oxycitronellal, phenyl acetaldehyde, piperonal, and other synthetic fragrances, as well as blended fragrances prepared by blending at least two or more of these, can be used. On the other hand, as the spherical adsorbent, any adsorbent can be used, such as solid particulate adsorbents such as silica, alumina, silica alumina, and zeolite. Some are preferably used. Moreover, the particle size is 2
Preferably, the thickness is in the range of 10 mm to 10 mm. The granular deodorizer of the present invention is advantageously used as a deodorizer to be added to the dust collection bag of a vacuum cleaner. The amount of deodorant added to the dust collection bag is sufficient with just a few particles, and by taking advantage of the fact that it is a solid granule and fluid, it can be added to the dust collection bag by suctioning it from the suction port of the vacuum cleaner. Addition can be easily carried out. The deodorizing agent added to the dust collection bag exhibits the aromatic deodorizing effect until the bag becomes full of dust and the suction effect is reduced, thus exhibiting the excellent advantages mentioned above. That is, all of the solid adsorbents used in the present invention exhibit strong water absorption ability, and thus maintain the inside of the dust collection bag under dry conditions, and prevent bacteria due to the synergistic effect of α-bromocinnamic aldehyde and fragrance. It significantly suppresses the proliferation of microorganisms such as, etc., in the dust collection bag, and has excellent sanitary benefits. Example Powdered α-bromosinnamic aldehyde (BCA) was added to a liquid fragrance (osmanthus osmanthus),
When stirred at room temperature, it dissolved easily to form a clear solution. This solution has a pore volume of 0.67 cc/g and approximately 5 mm
A predetermined amount of activated alumina having an average particle size of For comparison, powdered α-bromocinnamic aldehyde was dissolved in a small amount of benzene, and this solution was impregnated into the granular activated alumina, which was then air-dried for 2 hours at room temperature to form the comparative granular deodorant of Sample 3. Manufactured. In addition, a comparative granular deodorant of Sample 4 was produced by impregnating the granular activated alumina with a single fragrance. In addition, each compounding ingredient is shown in Table 1 below. The following antibacterial test was conducted on these deodorants. Bacteria include A. Esherichia coli (U-
5-41, hereinafter simply abbreviated as E.Coli), B Staphyrococcus Aureus IFO-12732, hereinafter simply abbreviated as Stap.aureus), C Aspergillus niger.
niger (hereinafter simply abbreviated as Asp. niger), and the following were used. 15 ml of the culture medium to which the bacterial solution was added was poured into each 90 ml diameter shear dish, and allowed to cool to room temperature and solidify. A small 50 mm diameter peter dish was fixed in the center of the lid of each dish, and 3 g of the sample was filled into it.
On top of this lid, the shear dish containing the culture medium was placed upside down. After this, E.Coli and Stap.aureus
Asp. niger was cultured at 37°C for 24 hours, and Asp. niger was cultured at 25°C for 48 hours, and the inhibitory effect on bacterial growth was observed. The results obtained are shown in Table 1 below. In Table 1, in the indication of antibacterial properties, 59φ indicates that an inhibition zone of 59 mm in diameter appears with respect to the growth of bacteria on the medium. The x mark indicates that no difference in effectiveness was observed in inhibiting bacterial growth compared to the control. The mark △ indicates that a slight effect was observed in inhibiting bacterial growth compared to the control. The circle mark indicates that the effect of inhibiting bacterial growth was observed throughout the medium, and almost no bacterial growth was observed.

[Table] According to the results in Table 1 above, when α-bromosinnamic aldehyde, a sublimable powder antibacterial agent, is dissolved in fragrance and supported on a granular solid adsorbent, it is adsorbed by itself. It is understood that a significantly superior antibacterial effect can be achieved compared to the above.
