Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair styling composition having both a hair dyeing effect and a hair styling effect.

[0002]

The most common hair problems among middle-aged and elderly men are hair loss and gray hair. Among them, for white hair, a permanent hair dye containing paraphenylenediamine as an active ingredient, which is conventionally called a hair color, has been used. However, such a permanent hair dye has a problem that the hair dyeing work is troublesome and troublesome, and after a few months, the hairline becomes white and the whole hair becomes reddish. In recent years, in order to solve such a problem, there has been a demand for a hair dye that can be easily dyed and is suitable for frequent hair dyeing.

[0003] In response to such a demand, a primary hair dye containing an extremely large amount of an acid dye as a main component has been developed as a cosmetic which is capable of dyeing gray hair in a black color by a simple but simple means.

On the other hand, a so-called "gradual hair color" has been proposed, which is capable of gradually dyeing gray hair in daily hair care behavior. Examples of such a granular hair color include, for example, JP-A-61-55483 and JP-A-SHO-6.
No. 3-41414 and JP-A-2-231414,
A method for dyeing hair by binding iron ions and organic acids is described.

Further, many methods have been proposed in which the gray hair is simply made inconspicuous without dyeing the hair. For example, a method of fixing the hairstyle with strong hair styling to reduce the exposure rate of white hair, and a method of imparting wet luster and strong gloss to making it difficult to distinguish between white hair and black hair have been proposed.

[0006]

However, the above-mentioned simple hair dye and the hair styling agent for making gray hair inconspicuous have the following problems. First, since the primary hair dye contains a large amount of dye, it has the drawback that it may run off with sweat or rain to stain the skin or clothing, or the bedding at bedtime.

Further, the above-mentioned gradation hair color is
Since it uses the bond with iron ions and organic acid, it produces an iron rust-like odor. In addition, it is necessary to react iron ions with an organic acid during use, so two types of products must always be used.

Further, the hair styling agent which makes the white hair less noticeable by the hair styling naturally does not have the effect of dyeing the white hair. For this reason, the problem of gray hair is not completely solved and is insufficient. The present invention has been made in view of the above points, and an object of the present invention is to provide a hair styling composition that can very easily dye white hair.

[0009]

[Means for Solving the Problems] In order to solve the above problems, the present inventors have studied a hairdressing composition capable of gradually dyeing gray hair to black by performing daily hairdressing behavior. It was However, since the conventional hair styling composition contains a hair styling base, it is difficult to mix a hair dyeing component, and even with an acid dye that can be mixed, the hair styling base forms a film on the hair surface. Therefore, the adsorption (adhesion) of the acid dye to the hair is hindered.

Then, the inventors of the present invention have conducted extensive studies to increase the adhesion (adsorption) of the dye to the hair and, as a result, have a high compatibility with the acid dye and a high affinity with the hair. By blending a specific component, specifically, a surfactant having an amide group in the molecule, which is hydrophilic and does not easily form a complex with an acid dye, into the hair styling composition, hair dyeing can be performed. It has been found that a highly effective hair styling composition can be obtained, and the present invention has been completed. That is, the present invention includes (a) at least one of the compounds represented by the general formula (1) shown in Chemical formula 3 and the general formula (2) shown in Chemical formula 4,

[0011]

[Chemical 3] (In the formula, R ₁ is a fatty acid residue, R ₂ is CH ₂ CH ₂ OH,
R ₃ represents CH ₂ CH ₂ OH or H)

[0012]

[Chemical 4] (In the formula, R ₄ is a fatty acid residue, X ₁ is an alkali metal or lower amine, X ₂ is an alkali metal, lower amine or H
(B) 0.03% by weight of an acid dye and (c) a hair styling base material, and a pH of 2 to 6 is provided.

Here, the hair styling base material is preferably at least one of polyoxyalkylene glycol ether and amphoteric or nonionic polymer resin. Hereinafter, the present invention will be described in more detail.

Component (a) which is the first essential component of the present invention
The compounds represented by the general formulas (1) and (2) [hereinafter, referred to as compounds (1) and (2)] each have an amide group in the molecule, are hydrophilic, and are acidic dyes. It is a surfactant that does not easily form a complex with and is a component widely used in hair cosmetics. These compounds (1), (2)
Is mainly for the purpose of cleaning effect in shampoo, and also
It is used as a foam-forming agent in foamy hair styling products. Specifically, examples of the compound (1) include lauric acid diethanolamide, coconut oil fatty acid diethanolamide, stearic acid diethanolamide, myristic acid monoethanolamide, and palmitic acid monoethanolamide. In addition, as the compound (2), N-lauroyl-L-glutamic acid monosodium salt, N-coconut oil fatty acid acyl-L-monosodium salt, N-cured tallow fatty acid acyl-L-glutamic acid monosodium salt,
N-myristyl-L-glutamic acid disodium salt, N
There are: coconut oil and fat acid acyl-L-glutamic acid monotriethanolamine salt and N-lauroyl-L-glutamic acid monotriethanolamine salt. More specifically,
Examples of the compound (1) include compounds commercially available from Kawaken Fine Chemicals under the name of amizole, and examples of the compound (2) include compounds commercially available from Ajinomoto under the name of Amisoft.

The compounding amounts of these compounds (1) and (2) are not particularly limited, but in order to obtain a satisfactory hair dyeing effect, preferably 0.1% by weight or more based on the total composition, More preferably, it is 0.3% by weight or more. The upper limit of the compounding amount of the compounds (1) and (2) is preferably 10
Appropriately less than 5% by weight, more preferably less than 5% by weight. This is because the compounds (1) and (2) are hydrophilic surfactants, and therefore, in a system in which the compounding amount is too large, the attached (adsorbed) acid dye is easily desorbed at the time of washing the hair.

Component (b) which is the second essential component of the present invention
As the acid dye, the acid dye used in ordinary hair cosmetics can be used. For example, Acid Red
(Legal dye name: Red No. 106), Lithol Rub
image B (Red: No. 201), Vio Lamin
e R (same: Red No. 401), Tartrazine
(Same as: Yellow No. 4), Sunset Yellow FC
F (the same: yellow 5), Quinoline Yello
w (the same: yellow No. 203), FastGreen FCF
(Same as: Green No. 3), Pyranine Conc.
(Same as: Green No. 204), Brilliant Blue
FCF (Same: Blue No. 1), Indigo (Same: Blue 2)

No. 5), Orange II (the same: orange No. 205), Res
orcine Brown (brown No. 201), Al
izurol Purple (same: purple No. 401), N
aphehol Blue Black (the same: black 40
No. 1) etc. can be used. Of these acid dyes, black 401 and purple 40 are especially required to dye white hair black.
The combination of No. 1 and No. 205 orange is the most suitable.

The total content of these acid dyes is preferably in the range of 0.03 to 1.0% by weight based on the total composition. If the total content is less than 0.03% by weight, a sufficient hair dyeing effect cannot be obtained, and if it exceeds 1.0% by weight, it may tend to stain the skin, clothes, bedding, etc. due to sweat or rain. is there. A more preferable blending amount is 0.05 to 0.3% by weight.

The acid dye is a component that has been widely used as a colorant for increasing the added value of products, and a combination example with the above-mentioned component (a) or (c) is already known. .. However, the conventional purpose of using the acid dye is to color the product, and its blending amount is extremely small (for example,
0.000001 to 0.001% by weight). On the other hand, in the present invention, the acid dye is intended for dyeing hair, and the compounding amount thereof is several tens of times of the conventional amount.

Component (c) which is the third essential component of the present invention
Examples of the hair styling base include (i) polyoxyalkylene glycol ether and its derivatives, and (ii)
Amphoteric polymeric resins or nonionic polymeric resins can be used. Examples of the polyoxyalkylene glycol ether of (i) and its derivatives include compounds represented by the general formula (3). _{R'-O- (R'1 O)} x - (CH 2 -CH 2 -O) y -R '' (3) ( wherein, R'is an alcohol having 1 to 12 carbon atoms, sugar alcohol or carbon Residue of polyhydric alcohol of number 2 to 6, R
′ ₁ is an alkylene group having 3 to 4 carbon atoms, and x is 0 to 20.
0 mol, y is 0 to 200 mol (however, x and y do not become zero at the same time), R '' is hydrogen or an inorganic acid such as phosphoric acid, an organic acid such as succinic acid, adipic acid or fatty acid. Indicates ester residue of acid)

This polyoxyalkylene glycol ether is, for example, a polyhydric alcohol such as glycerin, pentaerythritol, trimethylolpropane, trimethylolethane, mannitan, sorbitan, diglycerin or sorbitol, or a monosaccharide, disaccharide, A compound obtained by addition-polymerizing 0 to 200 mol, preferably 15 to 50 mol of propylene oxide (PO) and at least one of butylene oxide (BO) in a mother nucleus of a sugar alcohol such as an oligosaccharide, or in the mother nucleus. At least one of PO, BO, and 0-200 mol, preferably 15-50 mol, and ethylene oxide (EO) 0-2
Random or addition-polymerized compound of 0 mol, preferably 1 to 10 mol [in the general formula (3), R ″ =
H's].

Examples of the derivatives of polyoxyalkylene glycol ethers include the esters of polyoxyalkylene glycol ethers and acids listed above. Specific esters include saturated aliphatic dicarboxylic acids such as adipic acid, succinic acid, malic acid and tartaric acid; oxydicarboxylic acids having 4 carbon atoms; inorganic acids such as phosphoric acid; fatty acids such as isostearic acid and polyoxyalkylene glycols. Obtained by esterifying with ether.

The polyoxyalkylene glycol ether of the general formula (3) described above is widely used as a hair styling base, for example, JP-A-53-124628.
No. 52-051035 and No. 56-083414.
No. 50-126841 and the like.

The amount of the polyalkylene glycol ether (i) and its derivative to be blended depends on the desired strength of the hair styling. Since the mechanism for expressing the hairdressing effect of this hairdressing base is the adhesion between the hairs due to the adhesiveness, a product with a low hairdressing effect usually has a composition of about 5% by weight, based on the total composition.
For products with strong hair styling properties, a blending amount of about 20% by weight is preferable. However, this does not apply when it is used in combination with another hair styling base.

The polymer resin (ii) is, for example, a compound of the general formula (4) shown in Chemical formula 5 as an amphoteric polymer resin, and a general formula shown in Chemical formula 6 as a nonionic polymer resin. An example is the compound of formula (5).

These polymer resins are widely used as a hair styling base, and are disclosed, for example, in JP-A-63-27551.
No. 5, JP-A-3-58912, and the like, its application is shown.

The compounding amount of the polymer resin (ii) depends on the desired strength of hair styling. The hair styling effect of these polymer resins is exhibited by forming a hard coating on the hair surface, and the strength of the hair styling depends on the hardness and adhesive strength of the coating itself. Usually, for products with low (weak) hair styling, a compounding amount of about 1% by weight based on the total composition, and for products with strong hair styling, about 5% by weight is preferable. However, this does not apply when it is used in combination with another hair styling base.

The hair styling composition of the present invention preferably has a pH within the range of 2 to 6. If the pH exceeds 6, a sufficient hair dyeing effect cannot be obtained. On the other hand, if the pH is less than 2, the hairdressing composition is a product directly applied to the human body and is safe (irritating). This is because it is not preferable from the aspect. A more preferable pH is 3-5.

Conventional pH adjusters can be used to adjust the pH of the composition in this manner. The pH adjuster is
The compound is not particularly limited as long as it is a compound that can be used in cosmetics, and examples thereof include organic acids such as citric acid, succinic acid, tartaric acid and salts thereof, amines such as triethanolamine and 2-aminomethylpropanol, hydrochloric acid, phosphorus. It is an inorganic acid or an inorganic base such as acid, sulfuric acid, acetic acid, sodium hydroxide or potassium hydroxide. Furthermore, the hairdressing composition of the present invention may contain the following known components within a range that does not affect the effects of the present invention.

For example, ultraviolet absorbers (eg, oxybenzone and its derivatives), nonionic surfactants (eg, polyoxyethylene hydrogenated castor oil), cationic surfactants (eg, stearyltrimethylammonium chloride). ), Anionic or amphoteric surfactants,
Oily components (for example, silicone oil, animal and vegetable oils, ester oils, etc.), germicidal preservatives (for example, isopropylmethylphenol, paraoxybenzoic acid esters, etc.), amino acids,
Proteolytic products, various vitamins, plant extracts, ethanol, propylene glycol, 1,3-butylene glycol, and glycerin can be mentioned.

The present invention provides, for example, liquid hair styling products such as hair liquids and hair oils, highly viscous hair styling products such as hair pomades and hair gels, spray hair styling products such as hair sprays and set lotions, and foamy hair styling products such as hair foams. It can be applied.

[0035]

In the hair styling composition of the present invention, since the compounds (1) and (2) of the component (a) are both highly compatible with the acid dye and have high affinity with the hair, the acid dye Even when used in combination with, it can be easily incorporated into the composition and can prevent the hair dye base from hindering the adsorption of the acid dye to the hair. Thereby, a sufficient hair styling effect and hair dyeing effect can be exhibited.
