近年、生活水準の向上に伴い環境衛生に対する一般の関心が高くなっている。かかる事情から、一層効果の高い消臭剤が必要とされ、特に多様な臭気成分に対して有効な消臭剤が求められている。
悪臭成分を低減する方法としては、強力な芳香剤により臭気をマスキングする方法、活性炭、アルミナ、ゼオライト等の多孔質吸着剤による吸着などの物理的方法、触媒燃焼法やオゾンによる酸化法、化学薬品を用いた中和法などの化学的方法、あるいはバクテリアによる分解などの生物化学的方法等が知られている。
上記化学的方法による消臭剤は、アンモニア、アミン類等のチッソ系成分やメルカプタン、硫化水素等のイオウ系の成分に対しての効果はあるものの、有機酸には有効性が低く、より巾の広い臭気成分に対して消臭効果を有する消臭剤が求められている。
In recent years, general interest in environmental sanitation has increased with the improvement of living standards. Under such circumstances, a more highly effective deodorant is required, and a deodorant effective particularly against various odor components is demanded.
As a method of reducing malodorous components, a method of masking odor with a strong fragrance, a physical method such as adsorption with a porous adsorbent such as activated carbon, alumina, zeolite, etc., a catalytic combustion method or an oxidation method with ozone, a chemical A chemical method such as a neutralization method using bismuth, or a biochemical method such as degradation by bacteria is known.
The deodorant by the above chemical method has an effect on nitrogenous components such as ammonia and amines and sulfur components such as mercaptans and hydrogen sulfide, but is less effective for organic acids. There is a need for a deodorant having a deodorizing effect on a wide range of odor components.

タバコ臭やゴミ臭などは、様々な臭気成分より構成されている。本発明の目的は、日常生活における悪臭、異臭であるタバコ臭やゴミ臭など、多様な成分を含む臭気を効果的に除去できる消臭剤を提供することにある。
本発明者は、前記の課題を解決すべく種々検討を重ねた結果、ケトン基を含む有機酸及びグリオキシル酸(以下、これらを合わせてケト酸等ということがある)の金属塩が優れた消臭効果を示すとの知見を得て本発明を完成した。
Cigarette odors and garbage odors are composed of various odor components. An object of the present invention is to provide a deodorant capable of effectively removing odors containing various components such as bad odors in daily life, odors such as tobacco odor and garbage odor.
As a result of various studies to solve the above-mentioned problems, the present inventor has found that an organic acid containing a ketone group and a metal salt of glyoxylic acid (hereinafter, collectively referred to as keto acid or the like) are excellent in consumption. The present invention was completed by obtaining the knowledge that it shows an odor effect.

本発明は、グリオキシル酸金属塩及びケト酸金属塩から選ばれた1種以上の成分を有効成分とする消臭剤を提供するものである。
本発明消臭剤において、有効成分の酸成分としては、グリオキシル酸、ピルビン酸及びレブリン酸から選ばれた1種以上の成分であるのが好ましい。
