2. Description of the Related Art In recent years, brown hair whose hair has been bleached, especially for young people, and hair coloring such as dyeing the entire hair with various colors or partially meshing have been developed. boom. Various hair dyes have been used to carry out these hair colorings. Generally, hair dyeing methods include permanent hair dyes and semi-permanent hair dyes from the viewpoint of the persistence of the color of colored hair. And temporary hair dyes. Permanent hair dyes and semi-permanent hair dyes have high color continuity, but have a disadvantage that the hair dyeing operation is complicated, and if the hair dyeing fails, it cannot be restored. On the other hand, temporary hair dyes are also easy to use and can be easily removed by washing them off with shampoo.

Conventionally, a temporary hair dye is prepared by applying a solution in which a pigment is dispersed or a spray in which an aerosol propellant is filled in an aerosol can to the surface of the hair and fixing it by drying. In general, various fixing agents are added to the composition to enhance the fixing force.

For example, JP-A-63-218613 and JP-A-63-218614 disclose copolymers of an anionic polymerizable unsaturated monomer such as acrylic acid and an alkyl ester of acrylic acid. A hair dye composition containing an anionic resin and a pigment is disclosed in JP-A-54-6.
No. 7039 and JP-A-60-36571 disclose a hair dye composition containing a zwitterionic resin comprising a copolymer of a monochloroacetic acid amine salt of a tertiary amine-containing methacrylate and an alkyl ester of acrylic acid, and a pigment. Is disclosed.

[0005] However, the temporary hair dye composition using these resins as a fixing agent has a sufficient function of fixing power, but when rubbed with clothes or cloth, the pigment is transferred to the clothes. There is a problem in terms of rub resistance, that is, soiling, and stickiness and stiffness, in which the resins adhere to each other to give a feeling of incongruity due to the stickiness and stiffness of the hair, thereby deteriorating the feel.

[0006] Further, among the temporary hair dyes currently available on the market, those using carbon black as a colorant lack the abrasion resistance and have the problem that once they are attached to clothes they do not fall off even after washing. It is extremely difficult to partially dye the hair in the spray form, and the feeling of use due to stiffness is inferior. Therefore, it is excellent in concealing properties and rub resistance, and has no stickiness or stiffness and has uniform hair dyeing. There is a strong demand for a temporary hair dye that has excellent usability.

[0007]

Under such circumstances, the present inventors have made intensive studies and found that a temporary hair dye containing a specific pigment, a gelling agent and an oil agent solves the above-mentioned problems. Was found. Further, they have found that the effect is further enhanced by using a film-forming polymer in combination, and completed the present invention. That is, the invention of claim 1 of the present invention is a gel-like temporary hair dye composition comprising a pigment having a pearl luster, a gelling agent, and an oily substance. The invention according to claim 2 of the present invention contains a film-forming polymer.
A gel-like temporary hair dye composition according to item 1.

[0008]

Embodiments of the present invention will be described below in detail. The pigment having a pearl luster used in the present invention includes the following. 1. Mica titanium. 2. Mica titanium coated with one or more colored pigments selected from carmine, konjo, ultramarine, black iron oxide, red iron oxide, yellow iron oxide, chromium oxide, and chromium hydroxide. 3. Mica titanium coated with one or more selected from azo pigments, acid dyes, phthalocyanine pigments, threne pigments, quinacridone pigments, dioxazine pigments, isoindolinone pigments, and the like. Preferred among these pigments are titanium mica and carmine, konjo, ultramarine blue, black iron oxide, red iron oxide, yellow iron oxide, chromium oxide, colored pigments such as chromium hydroxide, red 404, red 226, red 202 No. 2, Red No. 206, Yellow No. 401, Blue No. 404, etc. are mica titanium coated with one or more selected from azo dyes which are not laked by transition metals. These pigments having a pearl luster can be used alone or in combination of two or more, and the compounding amount is 5 to the total amount of the composition.
If the content is less than 5% by weight, the desired hiding power cannot be obtained, and if it exceeds 40% by weight, the resulting composition is not suitable for uniform coloring due to poor adhesion during use.

The gelling agent used in the present invention includes carboxyvinyl polymer, alkylacrylic acid-acrylic acid copolymer, polyacrylamide and the like. The carboxyvinyl polymer is commercially available under the trade names of Carbopol (manufactured by BF Goodrich Chemical Co., Ltd.) and Hibiswako (manufactured by Wako Pure Chemical), and the alkylacrylic acid-acrylic acid copolymer is PEMULEN (B F. Goodrich Chemical Co., Ltd.) and polyacrylamide under the trade name Sepigel (Sepic). These gelling agents can be used singly or in combination of two or more. The compounding amount of the gelling agent is preferably 0.1 to 5% by weight based on the total amount of the composition,
If the amount is less than 0.1% by weight, there is a problem in stability due to precipitation of the pigment and the like. If the amount exceeds 5% by weight, the viscosity is high, and the stickiness during use is poor, which may be undesirable.

These gelling agents are usually used together with a neutralizing agent, for example, alkanolamines such as diisopropanolamine and triethanolamine, ammonia, potassium hydroxide, sodium hydroxide, basic Examples include amino acids (lysine, arginine and the like), basic polypeptides and the like. The compounding agent for the neutralizing agent varies depending on the type of the gelling agent used, but is usually added at a ratio of 0.2 to 5 times the amount of the gelling agent.

The oily substances used in the present invention include castor oil, olive oil, avocado oil, macadamia nut oil,
Fats and oils such as jojoba oil, waxes such as lanolin, glyceryl esters of linear or branched fatty acids such as glyceryl-2-ethylhexanate, glyceryl-tri-isostearate, isopropyl myristate, and octyldodecyl isostearate. Alkyl esters of linear or branched fatty acids, hydrocarbons such as liquid paraffin, squalene, petrolatum, and silicones such as methylpolysiloxane, highly polymerized methylpolysiloxane, methylphenylpolysiloxane, and polyoxyalkylene-modified silicone derivatives. . These oily substances can be used alone or in combination of two or more. The amount of the oily substance is preferably 0.5 to 20% by weight based on the amount of the composition. If the amount is less than 0.5% by weight, the dispersibility of the pigment is poor, and the pigment becomes uneven in the preparation. If the ratio exceeds the above, stickiness may occur or friction resistance may decrease, which may be undesirable.

The gel-like temporary hair dye composition of the present invention includes:
Further, a film-forming polymer can be contained. By adding an appropriate amount of a film-forming polymer, the friction resistance can be improved and discoloration due to moisture such as sweat or rain can be prevented. Examples of the film-forming polymer used here include a nonionic polymer compound and an amphoteric polymer compound. Examples of the nonionic polymer compound include polyvinylpyrrolidone (Rubiscol K, manufactured by BASF), a copolymer of vinylpyrrolidone and vinyl acetate (Rubiscol VA, manufactured by BASF),
And a copolymer of vinylpyrrolidone and dimethylaminoethyl methacrylate (Copolymer 937, manufactured by ISP). Examples of the amphoteric polymer compound include a monoalkylacetic acid amphoteric product of a dialkylaminoethyl methacrylate polymer (Yuka Former, manufactured by Mitsubishi Chemical Corporation). Nonionic polymer compounds are slightly superior to amphoteric polymer compounds in that they do not impair the viscosity of the gelling agent. The amount of the film-forming polymer to be added is preferably 0.2 to 10% by weight based on the total amount of the composition.
If the amount is less than 2% by weight, a sufficient effect cannot be obtained.

In the composition of the present invention, besides the above-mentioned components, for example, an emulsifier for stabilizing the emulsion and a colorant for stabilizing the color tone can be added as long as the effects of the present invention are not impaired. . As an emulsifier, any of anionic, amphoteric, cationic and nonionic surfactants can be used. Various tar dyes can be used as the coloring agent. Further, in order to increase the commercial value, a fragrance or a pigment may be added. Further, a preservative, a sequestering agent, a pH adjuster, to prevent aging of the composition over time,
An ultraviolet absorber or an antioxidant, and a humectant such as glycerin or propylene glycol can also be added.
