Description

  The present invention relates to a gel hair styling agent containing an alkali thickener and an alkali agent. More specifically, the present invention relates to a gel-type hair styling agent that suppresses stickiness, sagging, and creaking, and has improved coatability, moisturizing power, and re-styling properties.

Conventionally, hair creams, pomades, hair lotions, hair waxes and the like have been frequently used as hair styling agents. Since these hair styling compositions contain a large amount of hair styling ingredients such as fats and oils or waxes, they have a sticky feeling when applied to the hair, are difficult to dry, and tend to give a heavy finish.
Under such circumstances, a gel-like hair styling agent in which a gel is formed by blending an alkali thickener and an alkali agent has come to be frequently used. By making it into a gel, it is possible to give a feeling of transparency not found in conventional hair styling products and to improve the feeling of use when applied to hair or after application, and the demand for hair styling products is high. For this reason, a wide variety of gel-like hair styling materials have been proposed that further impart a hair styling effect, hair setting power, quick-drying property, and the like and are compatible with various usage modes.

For example, Patent Document 1 discloses a gel-type hair styling material that has an excellent hair styling retention effect and the like. The hairdressing material contains a specific alkyl monomer, a neutralizing agent, a water-soluble alcohol and an anionic polymer compound as essential components. Since this anionic polymer compound has a film-forming ability, it is excellent in the growth of hair styling when applied to hair, but the moisturizing power is still insufficient, and the quick-drying property of the hair styling provides the hair. The problem is that the hairdressing material adhering to the film solidifies more than necessary, and it is not possible to sufficiently suppress the occurrence of flaking (powdering) when passing a hand comb or brush through the hair for hairstyling again. is there.
JP 2002-167308 A

As described above, although the conventional gel-like hair dressing is excellent in quick-drying properties, flaking cannot be sufficiently reduced when hair that has been applied with a hair styling agent is tried again, and once applied and dried. After that, hair styling after that was difficult.
Therefore, the present invention provides a suitable moisturizing power and coatability while improving good hairstyling while maintaining good usability and quick-drying properties as a gel-like hairstyling agent, and suppresses stickiness, sagging, and wrinkles It is an object of the present invention to provide a gel-like hair dressing.

  The “sag” means a state in which, after applying the gel hairdressing agent to the hair, the hair after application is sagging without maintaining the hairstyling property.

The gel hair styling of the present invention is a gel hair styling containing an alkali thickener and an alkali agent, and in 100% by weight of the gel hair styling,
0.5 to 7.5% by weight of a nonionic polymer compound (A) comprising a vinylpyrrolidone-based copolymer,
Containing ethanol and polyhydric alcohol (B) in an amount of 20-40% by weight,
And the weight ratio of the said ethanol and a polyhydric alcohol is 1: 1.5-1: 4, It is characterized by the above-mentioned.

Furthermore, 0.01% of nonionic surfactant (C) is contained in 100% by weight of the gel hair styling agent.
You may contain in the quantity of 4 weight%.
The nonionic surfactant (C) is
Any one nonionic surfactant (c-1) of PEG-40 hydrogenated castor oil, PEG-50 hydrogenated castor oil or PEG-60 hydrogenated castor oil;
A nonionic surfactant (c-2) excluding (c-1),
And it is desirable that the weight ratio of said (c-1) and (c-2) is 1: 1-1: 5.

  Furthermore, in 100% by weight of the gel hair styling agent, hydroxyethyl cellulose (d-1) and / or hydroxypropyl cellulose (d-2) may be contained in an amount of 0.01 to 3% by weight.

The gel hair styling composition of the present invention not only has a specific nonionic polymer compound and excellent transparency and use feeling unique to the gel dosage form, but also contains ethanol and a polyhydric alcohol in a specific ratio. Therefore, moisturizing effect is high. For this reason, flaking can be effectively suppressed, and the re-styling property is excellent.
Furthermore, the gel-like hair dressing of the present invention can reduce the feeling of stickiness and wrinkles on the hair, and can give the glossiness that the wax agent mainly has, and has such a variety of performances in a well-balanced manner. As a result, it can be widely used not only by professionals but also by general users.

Next, the gel hairdressing material of the present invention will be specifically described.
The gel hair styling of the present invention is a gel hair styling containing an alkali thickener and an alkali agent, and is a nonionic polymer comprising a vinylpyrrolidone copolymer in 100% by weight of the gel hair styling. The compound (A), ethanol and polyhydric alcohol (B) are contained in specific amounts, and the weight ratio between the ethanol and the polyhydric alcohol is a specific value.

<Alkali thickener>
An alkali thickener forms a gel by hydrogen-bonding with the alkali agent mentioned later. When it is in a gel form, a transparent feeling is imparted, and a good usability can be imparted even when and after applying the hairdressing agent. The alkali thickener is not particularly limited as long as it is generally used in cosmetics. For example, a carboxyvinyl polymer having a structural unit represented by the following formula is representative.

Specific examples of such a carboxyvinyl polymer include commercially available carbopol 934, carbopol 940, carbopol 941, and carbopol Ultrez 10 (trade name, manufactured by BF Goodrich).
The alkali thickener is usually contained in an amount of 0.05 to 5% by weight in 100% by weight of the gel hairdressing material of the present invention. When the amount is such an amount, a good gel can be maintained as a hair styling agent, and the performance as the gel hair styling of the present invention is not adversely affected.

<Alkaline agent>
The alkali agent forms a gel by hydrogen bonding with the alkali thickener. Such an alkali agent varies depending on the type of the alkali thickener used. For example, alkanolamines such as triethanolamine, diisopropanolamine and aminomethylpropanol, potassium hydroxide, sodium hydroxide, basic Examples include amino acids.

The alkaline agent is usually contained in the gel hairdressing material of the present invention in an amount that is generally equivalent to the alkaline thickener. When the amount is such an amount, a good gel can be maintained as a hair styling agent, and the performance as the gel hair styling of the present invention is not adversely affected.
<Nonionic polymer compound comprising vinylpyrrolidone (A)>
The nonionic polymer compound (A) (hereinafter also referred to as nonionic polymer compound (A)) composed of a vinylpyrrolidone compound used in the gel hairdressing material of the present invention has a structural unit represented by the following formula: It is a high molecular compound which consists of the vinylpyrrolidone-type copolymer which has, and shows nonionicity.

Such a nonionic polymer compound (A) has a property of being spread on the hair to form a thin film, so-called film forming ability, and can give gloss to the hair. Furthermore, a moderate moisturizing effect can be maintained due to a synergistic effect with ethanol and polyhydric alcohol described later.
Specific examples of the nonionic polymer compound (A) include vinyl acetate / vinyl pyrrolidone copolymer, polyvinyl pyrrolidone, vinyl pyrrolidone / vinyl acetate / vinyl propionate copolymer, and vinyl pyrrolidone / dimethylaminoethyl methacrylate. A copolymer. Of these, vinyl acetate / vinyl pyrrolidone copolymer and polyvinyl pyrrolidone are preferable.

  These are usually contained in an amount of 0.5 to 7.5% by weight in 100% by weight of the gel hairdressing material of the present invention. If it is contained in an amount within the above range, it can retain sufficient hair styling power and can reduce the stickiness and creaking and give it an appropriate glossiness. Can give a light finish.

<Ethanol and polyhydric alcohol (B)>
Ethanol and polyhydric alcohol (B) are used for the gel hairdressing material of the present invention. In particular, the polyhydric alcohol is contained in a larger amount than that contained in the conventional gel hairdressing agent.

Ethanol is capable of imparting quick drying properties to the gel-like hair dressing of the present invention due to its volatility, and suppresses stickiness of the finished hair after the gel-like hair dressing is applied. It becomes possible to improve hair-styling.
The gel hairdressing material of the present invention contains polyhydric alcohol as an essential component, and is used in combination with the ethanol. The ethanol alone tends to emphasize quick-drying properties and has a good finish, but in general, after the hairdressing material is dried, the hairdressing material spread on the surface of the hair tends to solidify more than necessary. It tends to be firmly attached on the top. In such a state, after applying the hairdressing material, when trying to shape the hair with a hand comb, comb or brush, the hairdressing material firmly adhered to the hair surface peels off in a powdered state in a state of whitening, so-called frame King will occur. Once flaking occurs, flaking cannot be eliminated unless the hair is washed or the like, so that it is substantially impossible to re-hair.

  However, by adding polyhydric alcohol to a specific amount with respect to the content of ethanol, blending a larger amount than the amount of polyhydric alcohol blended in conventional gel hairdressing products. Thus, the high moisture retention can be imparted while moderately reducing the quick-drying property of ethanol due to the swelling property exhibited by the polyhydric alcohol, so that flaking as described above can be effectively suppressed.

Such a moisturizing effect is not caused only by the polyhydric alcohol contained in a specific amount, but is also slightly entangled with the film forming ability of the nonionic polymer compound (A) to effectively prevent flaking. Moisturizing properties can be imparted.
Specific examples of the polyhydric alcohol include diglycerin, glycerin, ethylene glycol, polyethylene glycol, propylene glycol, 1,3-butylene glycol, dipropylene glycol, hexylene glycol, sorbitol, and mannitol. Of these, diglycerin, glycerin, polyethylene glycol, dipropylene glycol, and 1,3-butylene glycol are preferable, and diglycerin or glycerin is more preferable.

These ethanol and polyhydric alcohol (B) are contained in an amount of 20 to 40% by weight in total of ethanol and polyhydric alcohol in 100% by weight of the gel hair dressing of the present invention, and contain ethanol and polyhydric alcohol. The amount is usually 1: 1.5 to 1: 4, preferably 1: 2 to 1: 3 by weight.
When ethanol and the polyhydric alcohol (B) are contained in an amount within the above range and in a weight ratio, an appropriate quick drying property can be imparted and a moisturizing power can be increased. It is possible to effectively suppress solidification, and it is possible to realize a gel-type hair styling agent with improved fleshing property and reduced hair styling. In addition, the stability as a hair styling agent is also maintained well, the stickiness and stickiness can be reduced, and good elongation can be exhibited even when applied to hair.

<Nonionic surfactant (C)>
By adding the nonionic surfactant (C) to the gel hair dressing of the present invention, the transparency can be further improved, and stickiness and wrinkle can be reduced. And a gel-like hairdressing agent that maintains these effects in a well-balanced manner.

Specific examples of the nonionic surfactant (C) include polyoxyethylene hydrogenated castor oil such as PEG-40 hydrogenated castor oil, PEG-50 hydrogenated castor oil, and PEG-60 hydrogenated castor oil. , PEG-20 sorbitan cocoate, sorbitan fatty acid ester, glycerin fatty acid ester, polyglycerin fatty acid ester, propylene glycol fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbit fatty acid ester, polyoxyethylene glycol fatty acid ester, polyoxyethylene Glycerin fatty acid ester, polyoxyethylene alkyl ether, polyoxyethylene phytosterol, polyoxyethylene castor oil, polyoxyethylene alkylamine, polyoxyethylene fatty acid amino acid And alkyl glucoside.

These nonionic surfactants are usually 0.01% in 100% by weight of the gel hairdressing material of the present invention.
-4 wt%, preferably 0.5-3 wt%. If it is contained in an amount within the above range, good transparency can be maintained, and stickiness and goreness can be effectively reduced.
Further, among the nonionic surfactants, PEG-50 hydrogenated castor oil, PEG-40
Any one of hydrogenated castor oil and PEG-60 hydrogenated castor oil is combined with the other nonionic surfactant, and both are in a weight ratio of 1: 1 to 1: 5, preferably 1: 1. It is good to contain so that it may become ~ 1: 3. Since the above PEG-50 hydrogenated castor oil, PEG-40 hydrogenated castor oil, and PEG-60 hydrogenated castor oil all show a paste-like form at room temperature (25 ° C.), other nonionic surface activity By being contained in the above-mentioned weight ratio with the agent, it is possible to maintain performance such as elongation during application, moist feeling, and re-styling in a balanced manner.

<Hydroxyethyl cellulose (d-1) and hydroxypropyl cellulose (d-2)>
By adding hydroxyethylcellulose (d-1) and / or hydroxypropylcellulose (d-2) to the gel hairdressing material of the present invention, the gel hairstyling material functions as a thickening aid, thereby stabilizing the hairstyling material.
