Description

Gel hair cosmetic

The present invention relates to a gel hair cosmetic. More specifically, it is a novel gel that can be sprayed in a mist, has no stickiness as a hair cosmetic, has a smooth and high feel, has an excellent straight effect, is stable without creaming, and has a transparent appearance. The present invention relates to a hair cosmetic composition.

Conventionally, gel cosmetics are used by taking the preparation in the palm and applying it to the skin or hair. For this reason, there is a problem in terms of usability because it is necessary to wash away the residue on the palm after use. Further, even when such a gel cosmetic is accommodated in a spray container and sprayed, it has been difficult to spray as a mist because of a highly viscous preparation. A technique disclosed in Patent Document 1 solves the above-described problems.

The technology of Patent Document 1 has an excellent effect that a transparent gel-like composition can be sprayed in a mist, and as a component that improves the feel of the hair, a component such as a water-soluble silicone or a humectant is blended. It was. However, in recent years, there has been a demand for even better hair feel. In general, in order to solubilize an oil or the like in a base so that the base becomes transparent, it is necessary to add a large amount of a surfactant, which causes stickiness and deteriorates the touch. Further, when blended as an emulsion, transparency is not obtained, and it gradually creams, so that stable blending has been technically difficult. Furthermore, it is difficult to blend a cationic surfactant, which is generally considered to have a good feeling, into a thickening system of an anionic polymer.

Thus, with the existing technology, it was technically difficult to achieve both a transparent gel form that can be sprayed in a mist and imparting a high touch to the hair.

Note that Patent Document 2 is further cited as a document disclosing a technique close to the present invention. In Patent Document 2, although a method for producing an O / W ultrafine emulsion external preparation is described, it is a transparent gel that can be sprayed in a mist, has no stickiness, and has a smooth and high feel. There is no description that suggests that a hair cosmetic that is excellent in straightening effect and does not cause creaming and that is stable is obtained.

X represents a halogen atom and R′SO ₄ (where R ′ is an alkyl group having 1 to 6 carbon atoms). As the halogen atom, Cl, Br, and I are preferable. R ′ is preferably an alkyl group having 1 to 4 carbon atoms, particularly 1 to 2 carbon atoms. In the present invention, it is particularly preferred that X is C ₂ H ₅ SO ₄ .

Also, t / u = 2/8 to 8/2, preferably t / u = 3/7 to 7/3. If t / u is less than 2/8, film formability is inferior, and there is a problem in setting power. On the other hand, if t / u exceeds 8/2, solubility in aqueous solvents (alcohol, water, etc.) and hair There is a problem in terms of affinity and the like, and it is easy to flake. Further, the hygroscopicity is increased, and stickiness is felt, which is not preferable.

In the present invention, as the component (a), the following formula (II)

[In the formula (II), t / u = 2/8 to 8/2. ]
The vinyl pyrrolidone / N, N dimethylaminoethyl methacrylic acid copolymer diethyl sulfate having the structural unit represented by the formula is most preferably used.

The carboxyvinyl polymer has no spinnability and has a property of increasing the viscosity by neutralization with alkali. However, since it has no spinnability, it has good “crisp” and is suitable for atomized spray. The carboxyvinyl polymer is mainly a polymer of acrylic acid, and is a synthetic polymer having a carboxyl group. Since the component (b) is “non-spinning”, a water-soluble cellulose derivative that is a spinnable thickener (for example, methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, carboxymethylcellulose, methylhydroxypropylcellulose, Etc.), sodium polyacrylate and the like are not included in the component (b) of the present invention.

It is preferably 20 to 70% by mass. If it exceeds 70% by mass, it is difficult to obtain a highly stable O / W single-phase microemulsion.

The blending amount of component (c) in the hair cosmetic composition of the present invention is preferably 0.001 to 5% by mass.

[Component (d)]
Examples of the cationic surfactant as the component (d) used in the present invention include alkyltrimethylammonium salts such as stearyltrimethylammonium chloride and lauryltrimethylammonium chloride, distearyldimethylammonium chloride dialkyldimethylammonium chloride, poly (N , N'-dimethyl-3,5-methylenepiperidinium), alkylpyridinium salts such as cetylpyridinium chloride, alkyl quaternary ammonium salts, alkyldimethylbenzylammonium salts, alkylisoquinolinium salts, dialkyl morpholiniums Examples thereof include salts, POE alkylamines, alkylamine salts, polyamine fatty acid derivatives, amyl alcohol fatty acid derivatives, benzalkonium chloride, and benzethonium chloride.

In the present invention, the component (a), the component (b), the component (c), and the component (d) are dissolved in an aqueous solvent. Examples of the aqueous solvent include water, alcohol solvents such as ethanol, and mixed solvents thereof.

For the production of the hair cosmetic composition of the present invention, for example, a production method including the following steps is mentioned as a preferred example. That is, it is preferable to mix | blend (c) component as an O / W ultrafine emulsion prepared through the one-phase microemulsion preparation process and the O / W ultrafine emulsion preparation process as shown below. In the O / W ultrafine emulsion, the particle size is 10 to 500 nm.

(I) Component (c) is added to and mixed with a nonionic surfactant, a polyoxypropylene / polyoxyethylene copolymer dialkyl ether, and an aqueous system having a water content of 40% by mass or less. Preparing a phase microemulsion,

The viscosity of the hairdressing cosmetic composition of the present invention can be adjusted, for example, by controlling the polymerization degree of the copolymer to be blended, increasing or decreasing the amount of polymer added, adjusting the blending amount of the aqueous solvent, and the like.

In the gel-like hair cosmetic composition of the present invention, the component (a) and the component (b) form a complex, and adjacent complexes form weak bonds due to cohesive force. As a result, there is a feeling of elasticity compared to a normal gel-like composition, and a uniform gel can be formed, and the degree of shaking and passage of pores (for example, passage of spray holes of a cosmetic sprayer) is about. The weak force due to aggregation between the composites is easily broken by the external force, so that it can be easily sprayed in the form of a mist during use.

Furthermore, even if the weak bond due to aggregation between the composites breaks down during use, the composites have the property of aggregating each other by allowing them to stand after use. A weak bond due to aggregation is made between the bodies, forming a gel with elasticity. Therefore, according to the present invention, the gel is formed at the time of standing, and can be easily sprayed in the form of a mist by spraying with a sprayer at the time of use. An entirely new type of gel composition is provided. This gel-like composition is excellent in the appearance of the appearance (gel feeling), and is also excellent in the touch during use. Also, the transparency is good.

The hair cosmetic composition of the present invention is excellent in transparency. Specifically, the L value which is an index of transparency is preferably 60 or more. In the present invention, the “L value” means a value measured by putting a predetermined amount of hair cosmetic into a quartz cell having an optical path length of 10 mm and transmitting white light having a wavelength of 380 to 770 nm using a transmission color difference meter. Say.

Further, in the present invention, by blending the component (c) as an ultrafine emulsion that has undergone the above-mentioned specific steps, it is possible to more effectively achieve both the balance between transparency and usability.

The hair cosmetic of the present invention may be blended with other components conventionally used in hair cosmetics, for example, depending on the form thereof, as long as the effects of the present invention are not impaired. Examples of such components include film-forming polymers, humectants, extracts, powder components, and fragrances.

The results are shown in Table 1. In Table 1, “vinyl pyrrolidone / N, N-dimethylaminoethyl methacrylic acid copolymer diethyl sulfate ^(*) ” was a polymer represented by the above formula (II) (molecular weight of about 1,000,000).
(Production method)
Examples 1 and 2 were produced as follows. That is, POE (20 mol) glyceryl isostearate (manufactured by Nippon Emulsion Co., Ltd., Emarex GWIS-120 (HLB14)) and POE methylpolysiloxane copolymer (manufactured by Shin-Etsu Chemical Co., Ltd., Silicone SC9450: HLB 5) Mixture (total HLB 7.7), POP (2 mol) · POE (9 mol) random copolymer dimethyl ether, and (c) component dimethylpolysiloxane (manufactured by Shin-Etsu Chemical Co., Ltd., silicone KF96-A6T) As a component (d), stearyltrimethylammonium chloride and water were mixed to obtain an O / W one-phase microemulsion in a region where the water content was 40% by mass or less. When the above O / W one-phase microemulsion is gradually added to an aqueous formulation (here, a part of ion-exchanged water and ethanol which are constituents of a hair cosmetic), the component (c) is eventually added. An O / W ultrafine emulsion having a particle diameter of 100 nm or less as a phase was obtained. This was mixed and stirred in an aqueous solvent containing the component (a), the component (b), and other compounding components (the remainder of ion-exchanged water and ethanol as constituents of the hair cosmetic) to obtain a sample.

In Comparative Example 1, each compounding component was mixed to obtain a solubilized sample.
