  It is intended to provide a novel deodorant composition which is excellent in the deodorizing effect, is capable of affording a deodorant composition by a convenient method, and shows no decrease in the deodorizing performance even after a long period of time, once the deodorant being prepared. Specifically, there is provided a deodorant composition containing, as the active component, a colored compound obtainable by reacting a polyphenol in a solvent showing alkalinity in the coexistence of an oxygen molecule at a reaction pH value of 6.5 or more. As a substitute for a polyphenol, use can be made of a plant extract containing a polyphenol but containing substantially no amino acid. It is also possible to further employ an amino acid. Furthermore, use can be made of a plant extract and/or a plant body containing a polyphenol and an amino acid.

  本发明旨在提供一种新型除臭剂组合物，该除臭剂组合物除臭效果极佳，能够通过简便的方法获得除臭剂组合物，并且在制备除臭剂后，即使经过很长时间，除臭效果也不会降低。具体来说，本发明提供了一种除臭剂组合物，该组合物含有一种有色化合物作为活性成分，该有色化合物可通过在反应 pH 值为 6.5 或更高时，使多酚在与氧分子共存的显碱性溶剂中发生反应而获得。作为多酚的替代品，可以使用含有多酚但基本上不含氨基酸的植物提取物。也可以进一步使用氨基酸。此外，还可以使用含有多酚和氨基酸的植物提取物和/或植物体。
