Description

  The present invention relates to an odor masking agent as a first agent of a two-component oxidative hair dye used for gray hair dyeing and the like, and more specifically, blended with the first agent as a coupler dye together with a main component oxidative hair dye. The present invention relates to a specific odor masking agent and a masking method possessed by α-naphthol.

  The present invention also relates to a first agent of an α-naphthol-containing two-component oxidative hair dye to which the masking agent is added.

  At present, so-called oxidation hair dyes are widely used as hair dyes including white hair dyes, and are becoming mainstream. Such an oxidative hair dye employs a two-component type in order to cause an oxidant to act on an oxidative dye to cause oxidative polymerization, and includes a main component oxidative dye, a direct dye, an alkali agent, a surfactant, a fragrance, and the like. It is comprised from 1 agent and the 2nd agent which contains oxidizing agents, such as hydrogen peroxide, as a main component.

  This type of hair dye of the two-component reaction type dyes hair by forming a pigment by allowing a colorless low-molecular oxidative dye to penetrate into the hair and performing oxidative polymerization in the hair.

  Oxidative dyes are divided into dye intermediates that develop color by their own oxidation and couplers that have various color tones by combining with these dyes, and a wide range of tones can be obtained by combining these.

  As the dye intermediate, paraphenylenediamine, paratoluylenediamine, N, N-bis (2-hydroxyethyl) -paraphenylenediamine, N-phenyl-paraphenylenediamine, 4,4′-diaminodiphenylamine, 2-chloropara Phenylenediamine, N, N-dimethylparaphenylenediamine, paraaminophenol, orthoaminophenol, paramethylaminophenol, orthotolylenediamine, 2,6-dichloroparaphenylenediamine, 2- (β-hydroxyethyl) -paraphenylenediamine , Diphenylamine, paraaminophenylsulfamic acid or salts thereof are used.

  The couplers are roughly classified into polyhydroxyphenols, aminophenols, and diamines. For example, resorcin, pyrogallol, catechol, metaaminophenol, metaphenylenediamine, 2,4-diaminophenol, 1 , 2,4-Benzenetriol, metatoluylenediamine, hydroquinone, α-naphthol, 2,6-diaminopyridine, 1,5-dihydroxynaphthalene, 5-aminoorthocresol, phloroglucin, 2,4-diaminophenoxyethanol, gallic acid Tannic acid, ethyl gallate, methyl gallate, propyl gallate, pentaploid, 1-methoxy-2-amino-4- (2-hydroxyethyl) aminobenzene, 5- (2-hydroxyethylamino) -2-methyl Phenol or its salt And the like have been used.

  Furthermore, as a dye other than the dye intermediate and the coupler, a direct dye may be blended for the purpose of improving dyeing.

  Examples of the direct dye include 4-nitrometaphenylenediamine, 4-nitroorthophenylenediamine, 2-nitroparaphenylenediamine, picramic acid, 1-amino-4-methylanthraquinone, 1,4-diaminoanthraquinone, 2-amino. -4-nitrophenol, 2-amino-5-nitrophenol or a salt thereof is used.

  The two-component oxidative hair dye is very convenient because it can dye hair in various colors according to the user's preference and has excellent hair dyeing power. Widely popular. Therefore, high quality maintenance is always required from the market.

  There are also a variety of hair color products that feature fragrance. Various fragrances are required to differentiate products and improve the feeling of use.

  In such a trend, among the various components included in hair dyes, many users have an unpleasant feeling about the Ammonia stimulating odor of alkaline agents, the amine odor of monoethanolamine, and the solvent odor. Numerous proposals regarding masking of such odors have been made (see Patent Documents 1 to 5).

  Α-Naphthol, which is specified as an active ingredient in hair dyes and blended into the first part of two-component oxidative hair dyes as a coupler, has a unique odor and is regarded as a problem in that it generates a strong odor in the product. However, compared with stimulating odors such as ammonia odor, the priority level for taking countermeasures was low, so that no specific study on odor masking has been conducted.

  However, as a recent general trend, interest in odors and fragrances has increased more than ever, and it has been pointed out that naphthol odor disturbs fragrance harmony in products.

  Therefore, although there is a strong demand for providing a fragrance compound having an excellent masking effect on α-naphthol odor, a part of the added masking agent fragrance compound is a core of other hair dye components, particularly the core. There was a problem that the dye reacts with the dye and changes or deteriorates over time.

  In short, when developing a new odor masking agent for the two-component oxidative hair dye, it is a component that does not impair the original function of the hair dye in addition to its high masking effect. is necessary.

However, since there are many kinds of fragrance compounds applied to hair dyes, and there are various chemical structures and actions, masking the naphthol odor effectively while adversely affecting the stability of the hair dye. It has been very difficult to provide a specific fragrance compound that does not affect.
