Description

[Detailed description of the invention] The present invention relates to a deodorant.

More specifically, the present invention relates to a deodorizing agent that eliminates the odor of organic substances that cause unpleasant odors to humans, such as chicken manure, pig manure, cow manure, fish, animal meat, and internal organs. In recent years, as living standards have improved or lifestyles have changed, concerns regarding odors have increased.

Odors in the home are changing both qualitatively and quantitatively due to the increased airtightness of houses and the increase in housing complexes and apartment complexes. In addition to households, bad odors emitted from livestock barns, feed factories, cleaning plants, etc. are now subject to legal regulations due to their impact not only on workers but also on nearby residents. In particular, recent advances in dietary habits have led to an increase in demand for livestock foods, and the scale of livestock housing facilities has also increased rapidly. However, there is still room for improvement in the environmental hygiene aspect of livestock farming, and livestock processing Due to the incompleteness of the odor, a foul odor is generated in the livestock barn, which spreads not only inside the livestock barn but also to a wide area outside the livestock barn, significantly interfering with the living environment of surrounding private homes and becoming a pollution problem. In addition, the foul odor in livestock barns has a negative impact not only on humans but also on livestock. For example, odors in poultry houses, especially basic odors such as ammonia and amines, inhibit the growth of chickens and cause them to become sick. As described above, improving the environmental hygiene of livestock housing has become an important issue in the livestock industry. Hitherto, as a deodorizing agent against such bad odors, Glioguizal has been widely used as disclosed in Hakama Kosho No. 52-12-87 and Japanese Patent Application Laid-Open No. 50-125980, but it is not always satisfactory. There wasn't.

That is, glyogysar is used at a pH of 2 or less in consideration of stability, but as a result, the range of use is limited. In other words, it has the disadvantage that it cannot be used in places where mortar, concrete, metal, etc. are present. Therefore, the present inventors conducted intensive research to find a drug that does not have the above drawbacks and has a good deodorizing effect. As a result, the lower aliphatic acylation product of a compound having active hydrogen has been found to be effective against bad odors, especially basic odors. The present invention has been completed based on the discovery that it exhibits an extremely excellent deodorizing effect.

That is, the present invention provides a deodorant characterized by containing an acetylated product of a polyhydric alcohol or a polyvalent amine as a deodorizing component.

Polyhydric alcohols used in the present invention include ethylene glycol, propylene glycol, diethylene glycol, glycerin, tromethylolpropane, bentaerythritol, glucose, sorbitan, sorbitol,
Lactose, satucrose, etc. can be listed.

In addition, examples of polyvalent amines that can be used in the present invention include amines represented by the general formula (11) such as ethylenediamine, propylenediamine, and diethylenetriamine.
Piverazine, dipropylene diamine, glycoluril, etc. can be listed. day 2N→R-NHchinR'
-NH2 [1' (in the formula, R and R' have 2 or 3 carbon atoms)
alkylene group, n represents 0 or 1.

) The acetylated product of the present invention can be easily synthesized by a commonly used method.

For example, it can be easily obtained by reacting the above-mentioned polyhydric alcohol or polyhydric amine with acetic acid or its anhydride, or by reacting an acetic acid halide. Specific examples of acetylated products include triacetin, trimethylolpropane triacetate, bentaerythritol triacetate, bentaerythritol tetraacetate, glycose bentaacetate, sorbitol hexaacetate, sutucarose octaacetate, tetraacetylethylenediamine, tetraacetylpropylenediamine. , tetraacetyldiethylerentriamine, tetraacetylglycoluril, etc. Although the mechanism by which the acetylated product of the present invention eliminates bad odors, particularly basic bad odors, is not necessarily clear, it is probably thought to be as follows.

That is, it is thought that this is because the hydrolysis product of the acetylated product and the malodorous component react to form a harmful compound. In the present invention, only acetylated products have a remarkable deodorizing effect, and higher fatty acid esters have little effect as shown in the comparative examples described later. The deodorant of the present invention usually contains 1 to 10% of the acetylated polyhydric alcohol or polyvalent amine as the deodorizing component.
It is used by sprinkling it on the source of the bad odor in the form of a 20% aqueous solution or suspension dispersion, but as mentioned above, acetylated products are easily hydrolyzed, so it is necessary to prepare an aqueous solution or suspension dispersion before use. desirable.

The present invention also provides a deodorizing agent containing the acetylated product of a polyhydric alcohol or polyvalent amine and an inorganic peroxide according to the present invention as a deodorizing component.

Examples of the inorganic peroxide include sodium percarbonate and sodium sulfate hydrogen peroxide adduct. The main feature of the present invention is that it contains an acetylated product of the above-mentioned polyhydric alcohol or polyvalent amine, but its form and composition can be freely selected depending on the type and location of the malodor source used, the degree of malodor, etc. Other auxiliary agents that do not interfere with the implementation of the present invention, such as coloring agents, flavoring agents, viscosity modifiers, surfactants, oxidizing agents, reducing agents, bactericides, insecticides, etc., may not interfere with the performance of the main agent. There is no problem even if it is contained within the range. EXAMPLES Hereinafter, the present invention will be explained in more detail with reference to Examples, but the present invention is not limited to these Examples.
