The present invention relates to a double component type deodorant which comprises a first deodorant component A containing a liquid mixture containing a polyphenol and an acid agent and a second deodorant component B containing an alkali agent and an aqueous solvent. These deodorant components A and B may be separately stored in different storage parts. According to the invention, mixed type malodors in which at least two or more kinds of a sulfur-containing compound, aldehydes, lower fatty acids, amines, and the like are mixed can be efficiently deodorized.

Liquid deodorant composition and deodorizing method

It is to provide a hair dye stabilizer capable of stably storing a readily oxidizable compound in a hair dye, especially an oxidizing dye intermediate or a coupler and effective for remarkably improving the offensive odor problem. Furthermore, it is to provide a hair dye stabilizer giving improvement in damage on the hair, hardly irritating the skin, and free from adverse effects on the dyeing ability of the hair dye. As the active component constituting the hair dye stabilizer, a compound which is a mercapto-hydrocarbon compound and/or a thiol alcohol compound and does not contain a functional group reactive with a dye intermediate or a coupler is used. A readily oxidizable compound and the like in a hair dye can be stably stored by the use of an extremely small amount of the stabilizer.
