Description

  The present invention relates to a hair cosmetic that can express an excellent three-dimensional feeling and bundled feeling, and can obtain a glossy feeling at the same time. The present invention also relates to a hair cosmetic that can last for a long time.

  Many consumers use hair cosmetics in creating hairstyles, including hair treatment and beauty treatment (for example, Non-Patent Documents 1 to 3). Among them, hair wax can be used both for volume down and up to express a three-dimensional feeling and bundled feeling, so it is used when creating various hairstyles. A hairstyle can be created by emulsifying and using an oil such as Delilla wax.

  However, hair wax has a demerit that it lacks the holding power to maintain the created hairstyle for a long time, and there is a problem that the fixed hairstyle collapses early. Therefore, a method of fixing a hairstyle created with hair wax with a hard spray is often used.

  In the current hairstyle market, it is not only the wax that can create various hairstyles as in the past, but also the development of hair cosmetics that exhibit good properties in terms of retention. It is. However, in reality, hair cosmetics that meet these requirements have not been realized.

As a technique that meets the above requirements, for example, a technique as disclosed in Patent Document 1 is also disclosed. This technology proposes "a cosmetic composition in which at least one water-dispersible linear sulfopolyester and at least one thickening polyurethane are blended in an appropriate ratio in an acceptable liquid for chemicals". . However, even in such a technology, the actual situation is that the recent demands cannot be met.

  As described above, there is a demand for the development of a hair cosmetic that exhibits not only a hair wax that can simply create various hairstyles as described above, but also exhibits good properties in terms of holding power. However, in reality, hair cosmetics that meet these requirements have not been realized. Further, in using such a hair cosmetic, it is also an important characteristic that the glossiness of the hair surface can be improved.

  The present invention has been made under such circumstances, and its purpose is to express a three-dimensional feeling and a bundled feeling like hair wax, and it has a feature in holding power as well as creating a hairstyle. That is, the present invention provides a hair cosmetic that maintains a hairstyle under high humidity and exhibits good characteristics that make it difficult for the hairstyle to collapse due to stress such as wind, and also has a good gloss feeling. There is.

  The hair cosmetic composition of the present invention that has achieved the above object includes (A) two or more types of polymer compounds for fixing hair having different film hardness, (B) an acrylic thickener, and (C) polyoxy. It has a gist in that it contains ethylene hydrogenated castor oil.

  In the hair cosmetic composition of the present invention, the hair fixative polymer compound, the acrylic thickener and the polyoxyethylene hydrogenated castor oil account for the proportion of the total hair cosmetic composition: 1.5 to 5.0% (meaning “mass%”, the same shall apply hereinafter), acrylic thickener: 0.5 to 2.0%, polyoxyethylene hydrogenated castor oil: 3.0 to 10.0% preferable.

  The hair fixative polymer used in the hair cosmetic composition of the present invention is a combination of an acrylic acid / methacrylic acid copolymer and an acrylic resin alkanolamine solution, and its mass ratio (acrylic acid / methacrylic acid copolymer) It is preferable that the combination: acrylic resin alkanolamine liquid) is 1: 3 to 2: 1. Specific examples of the acrylic acid / methacrylic acid copolymer include (acrylates / hydroxyalkyl acrylate) copolymers and (acrylamide / acryloyldimethyltaurine sodium / acrylic acid) copolymers. Further, specific examples of the acrylic resin alkanolamine liquid include (alkyl acrylate / diacetone acrylamide) copolymer aminomethylpropanol.

  The mass ratio of the acrylic thickener to the polyoxyethylene hydrogenated castor oil (acrylic thickener: polyoxyethylene hydrogenated castor oil) is preferably 1: 2 to 1: 7.

  If necessary, the hair cosmetic composition of the present invention may further contain (a) a urethane-based thickener in a proportion of 3.0% or less, or (b) an inorganic powder in a proportion of 30.0% or less. It can also be included.

  In the present invention, (A) two or more hair fixing polymer compounds having different film hardness, (B) acrylic thickener and (C) polyoxyethylene hydrogenated castor oil are contained. Hair cosmetics that not only create a hairstyle that can express an excellent three-dimensional feeling and bundled feeling like hair wax, but also exhibit good properties in terms of holding power and also in a glossy feeling. Realized.

  The present inventor can express a three-dimensional feeling and a bundled feeling like a hair wax, not only creates a hairstyle, but also exhibits good characteristics in holding power and also has a good gloss feeling. In order to realize hair cosmetics, we examined from various angles. As a result, in the hair cosmetic containing at least (A) two or more kinds of hair fixing polymer compounds having different film hardness, (B) acrylic thickener and (C) polyoxyethylene hydrogenated castor oil, The inventors have found that the object can be achieved brilliantly and have completed the present invention.

  As described above, the reason why the object of the present invention has been achieved by containing (A) to (C) has not been clarified, but can be considered as follows. It was. That is, in the hair cosmetic composition of the present invention, by using two or more kinds of polymer compounds for fixing hair having different film hardness, a film is formed without being mixed in the formed film. The provided film characteristics are exhibited, and the film has good durability against external forces. In addition to the effects of (A), it can be considered that by using (B) and (C) in combination, an elastic film is formed by these synergistic effects.

  The hair cosmetic of the present invention contains at least (A) two or more kinds of hair fixing polymer compounds having different film hardness, (B) an acrylic thickener, and (C) polyoxyethylene hydrogenated castor oil. However, the blending ratio of these (A) to (C) is the ratio of the total amount of the hair cosmetic, (A): 1.5 to 5.0%, (B): 0.5 to 2.0. %, (C): 3.0 to 10.0% is preferable.

  The reason for prescribing the preferable blending ratio of (A) to (C) is as follows. First, the hair fixing polymer compound (A) is itself composed of a two-phase polymer and exhibits an action that enables an elastic style throughout the day. By using the fixing polymer compound, an elastic and hard-to-break film is formed, and thereby durability against external force is improved. In order to exert such an effect, the blending ratio of the hair fixing polymer compound is preferably at least 1.5% as a ratio to the entire hair cosmetic. However, if the blending ratio of the polymer compound for fixing the hair becomes excessive, the above effect is not only reduced, but also the hair feels sticky, so the ratio to the total amount of the hair cosmetic may be 5.0% or less. preferable.

  The “film hardness” is an index of the hardness of the film formed on the hair surface by the hair fixing polymer compound, and is measured by the following method. (JIS K5400-1990).

[Measurement method of film hardness]
Apply a certain amount of measurement sample as a solid content to a glass plate. At this time, application is performed so that the diameter is within 5 cm from the center of the glass plate. Thereafter, it is sufficiently dried by a dryer (60 ° C.). When the measurement sample uses an alcohol solvent, drying is performed for about 1 hour, and when the measurement sample is an aqueous solvent, drying is performed for about 3 hours. And it evaluates with the pencil shaved in the column shape with the sandpaper in a constant temperature and humidity chamber (temperature: 20 degreeC, relative humidity: 60%). Pencil hardness is prepared from soft to hard (6B <5B <4B <3B <2B <B <HB <F <2H <3H <4H <5H <6H <7H <8H <9H), JIS K5400 The film hardness is defined as the pencil hardness specified by the method specified in the “hand-drawing method”. At this time, in order to reduce the error in hardness determination, the measurement is performed by changing the position little by little at the number of measurement positions: 3 or more.

  The polymer compound for fixing hair used in the present invention is of two or more types having different film hardness, but from the viewpoint of forming a resilient and hard-to-break film, the “film hardness” of each component is as different as possible. It is preferable that the value be different (that is, a combination of those having a difference in hardness). In other words, when only a hair fixing polymer compound with a high film hardness is used, there is a setting force, but the film is hard, so it is brittle, and if the film breaks due to stress such as wind, the created hairstyle It will collapse. In addition, when only a hair fixing polymer compound having a soft film hardness is used, there is no set power and it is difficult to create a hairstyle.

  A preferred combination of two or more hair fixing polymer compounds having different film hardness is a combination of an acrylic acid / methacrylic acid copolymer and an acrylic resin alkanolamine solution. However, when used in combination as described above, it is preferable to adjust the blending ratio appropriately, for example, the mass ratio (acrylic acid / methacrylic acid copolymer: acrylic resin alkanolamine liquid), It is preferably 1: 3 to 2: 1.

  Examples of the acrylic acid / methacrylic acid copolymer as the hair fixative polymer include (acrylates / hydroxyalkyl acrylate) copolymers and (acrylamide / acryloyl dimethyl taurine sodium / acrylic acid) copolymers. Among them, (acrylates / hydroxyalkyl acrylate) copolymer is a copolymer of one or more hydroxyalkyl acrylate esters and one or more monomers consisting of acrylic acid, methacrylic acid or simple esters thereof. Examples include “Acudine DHR” and “Acudine 180” (both trade names: manufactured by Rohm and Haas Co., Ltd.). The (acrylamide / acryloyl dimethyl taurine sodium / acrylic acid) copolymer is a copolymer of acrylamide, acryloyl dimethyl taurine sodium and acrylic acid. Specifically, “Acudaine SCP” (trade name: Rohm and Haas) Manufactured by the same company).

  Examples of the acrylic resin alkanolamine liquid as the polymer compound for fixing hair include (alkyl acrylate / diacetone acrylamide) copolymer AMP (aminomethyl propanol). This (alkyl acrylate / diacetone acrylamide) copolymer AMP is a salt of (alkyl acrylate / diacetone acrylamide) copolymer and 2-amino-2-methyl-1-propanol (AMP). , “Plus Size L-9909B”, “Plus Size L-9540B”, “Plus Size L-75CB” (all trade names: manufactured by Kyoyo Chemical Co., Ltd.), and the like.

  Next, the acrylic thickener is an effective component for improving the hairstyle's holding power by improving the applicability of the hair cosmetic to the hair and imparting an appropriate viscosity to the hair cosmetic. is there. In order to exert such an effect, it is preferable that the blending ratio of the acrylic thickener is at least 0.5% as a ratio to the whole hair cosmetic. However, if the blending ratio of the acrylic thickener is excessive, not only the feeling in use becomes worse, but also the viscosity increases and the applicability is worsened. It is preferable to do.

  Examples of the acrylic thickener used in the present invention include (alkyl acrylate / steale methacrylate-20) copolymer, (acrylates / behenes methacrylate-25) copolymer, and (acrylates / steare methacrylate-20) crosspolymer. Is mentioned. Among them, the (alkyl acrylate / steale methacrylate-20) copolymer is a copolymer of methacrylic acid and steareth-20 ester and one or more monomers composed of acrylic acid, methacrylic acid or simple esters thereof. Specific examples include “Aculin 22” (trade name: manufactured by Rohm and Haas Co., Ltd.). The (acrylates / Beheneth-25 methacrylate) copolymer is a copolymer comprising an ester of methacrylic acid and behenes-25, and one or more monomers selected from acrylic acid, methacrylic acid or simple esters thereof. Specific examples include “Aculin 28” (trade name: manufactured by Rohm and Haas Co., Ltd.). Further, (Acrylates / Stearless Methacrylic Acid-20) Crosspolymer is a copolymer of one or more monomers composed of acrylic acid, methacrylic acid or a simple ester thereof, and steareth methacrylic acid 20 with trimethylolpropane or pentaerythritol. Cross-linked with allyl ether, and specific examples include “Aculin 88” (trade name: manufactured by Rohm and Haas Co., Ltd.).

  The acrylic thickener is thickened by neutralization with an alkali agent. Examples of the alkali agent used at this time include inorganic alkalis such as sodium hydroxide and potassium hydroxide, and basic amino acids such as arginine, but are not limited thereto.

  On the other hand, the polyoxyethylene hydrogenated castor oil (C) improves the applicability of the hair cosmetic to the hair and increases the holding power of the hairstyle by imparting tackiness to the hair cosmetic, and also the hair surface. It is an effective component for imparting a moderate gloss to the skin. In order to exhibit such an effect, it is preferable that the blending ratio of the polyoxyethylene hydrogenated castor oil is at least 3.0% or more as a percentage of the entire hair cosmetic. However, if the blending ratio of polyoxyethylene hydrogenated castor oil becomes excessive, not only will stickiness and the touch become worse, but also the viscosity will decrease and the holding power of the hairstyle will worsen, so the proportion of hair cosmetics as a whole Is preferably 10.0% or less.

  In the hair cosmetic composition of the present invention, the blending ratio of the acrylic thickener and polyoxyethylene hydrogenated castor oil may be adjusted to an appropriate range in order to improve coatability and hairstyle retention. It is valid. From this viewpoint, the mass ratio (acrylic thickener: polyoxyethylene hydrogenated castor oil) is preferably 1: 2 to 1: 7.

  If necessary, it is also useful to add a urethane thickener to the hair cosmetic composition of the present invention, and the retention of the hairstyle can be further enhanced by incorporating such components. However, if such a urethane thickener is contained excessively, the viscosity increases and the feeling of application becomes worse, so the content is preferably 3.0% or less (ratio to the entire hair cosmetic). .

  Examples of urethane thickeners that can be used in the present invention include (polyethylene glycol-150 / decyl alcohol / methylene diphenyl diisocyanate) copolymer and (polyethylene glycol-150 / stearyl alcohol / methylene diphenyl diisocyanate) copolymer. . Among these, the (polyethylene glycol-150 / decyl alcohol / methylene diphenyl diisocyanate) copolymer is a copolymer of polyethylene glycol (PEG) -150 and methylene diphenyl diisocyanate (SMDI) bonded at the ends with decyl alcohol. As a thing, "Aculin 44" (brand name: Rohm and Haas Co., Ltd. product) is mentioned. The (polyethylene glycol-150 / stearyl alcohol / methylene diphenyl diisocyanate) copolymer is a copolymer of polyethylene glycol (PEG) -150 and methylene diphenyl diisocyanate (SMDI) bonded at the ends with stearyl alcohol. "Aculin 46" (trade name: manufactured by Rohm and Haas Co., Ltd.).

  It is also useful to contain an inorganic powder as necessary in the hair cosmetic composition of the present invention, and the glossiness of the hair surface can be further enhanced by containing such an inorganic powder. However, since an excessive amount of such inorganic powder deteriorates the feel, the content is preferably 30.0% or less (ratio to the entire hair cosmetic). Examples of such inorganic powder include, but are not limited to, mica titanium, mica, titanium oxide, ferric oxide, ferric oxide, bitumen, carmine, borosilicate, and the like.

  In addition to the above components, the hair cosmetic of the present invention can also contain components (additives) that are usually added to hair cosmetics. These additives include proteins, amino acids, UV absorbers, humectants, fats and oils, lanolins, higher alcohols, fluorine compounds, silicones, cationized polymers, surfactants (positive Ionic surfactants, anionic surfactants, nonionic surfactants, amphoteric surfactants), thickening / gelling agents, deodorants, preservatives, chelating agents, pH adjustment Agents, acids / alkalis, solvents, anti-inflammatory agents, fragrances, pigments and the like can be mentioned, and these can be appropriately blended. In addition, the hair cosmetic composition of the present invention can be used for treating hair on a daily basis, and the gel type is optimal as the dosage form.

  Next, the present invention will be described more specifically by way of examples. However, the following examples are not intended to limit the present invention, and all modifications can be made without departing from the spirit of the above and following descriptions.
