Abstract: As a novel compound which is excellent in odor quality and has an odor of a very clear and strong woody note, the invention provides a compound represented by the following formula (1):

Abstract: 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.

Abstract: The present invention relates to a stable composition for hair dye, which comprises at least one compound selected from dihydrocitronellyl nitrile, 2,2,6-trimethylcyclohexane carboxylic acid ethyl ester, 2-ethyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-2-buten-1-ol, 2,2,6-trimethylcyclohexyl-3-hexanol, 1-(2-methyl-2-propenyloxy)-2,2,4-trimethylpentan-3-ol, thioglycerin, dibutyl sulfide, thiogeraniol, thiocineol, 2-methyl-4-propyl-1,3-oxathian, 4-methoxy-2-methyl-2-butanethiol and the like. The stable composition for hair dye has a superior effect in masking a malodor originated from components such as ammonia formulated in hair dye composition such as composition for hair dye, and is also stable in an alkaline product and an acidic solution product.
