Fragrant consumer products comprising oxidizing agents are described, which may be, for example, detergents or cleaners or, for example, also cosmetics. These consumer products comprise certain minimum amounts of fragrances of certain classes of substances. They are characterized by very good (storage) stability, both with regard to the fragrance of the product, and also with regard to the potency of the oxidizing agent.
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.
