Abstract
Description
[Technical Field]
[0001] The present invention relates to a hair cosmetic composition. [Background technology]
[0002] Hair cosmetic compositions containing cationic polymers and anionic polymers are known. For example, Patent Document 1 describes that by using a composition for treating keratinous materials, which is characterized by containing at least one anionic polymer and at least one cationic polymer in a solvent medium, the anionic polymer can be fixed to keratinous materials, which may include hair, skin, or nails in particular. It is hypothesized that the reason for the above effect is related to a complex formed by the interaction between the anionic polymer and the cationic polymer.
[0003] Patent Document 2 describes that a hair cosmetic containing a cationic polymer having a charge density within a specified range and an anionic polymer containing 80% by mass or more and 100% by mass or less of specified anionic constituent units and having a weight-average molecular weight of 4,000 or more and 80,000 or less can improve the feel and appearance of damaged hair, and can maintain these effects even after repeated washing.

[0004] [Patent Document 1] Japanese Unexamined Patent Publication No. 53-139734 [Patent Document 2] Japanese Patent Application Laid-Open No. 2005-166333 Summary of the Invention [Problem to be solved by the invention]
[0005] As described in Patent Document 1, it is known that a complex formed from a cationic polymer and an anionic polymer (hereinafter also referred to as a "polyion complex") can be used as a composition for treating keratinous materials. However, there is still room for improvement in terms of improving the performance when used as a hair cosmetic composition. For example, hair conditioners, which are a type of hair cosmetic composition, are required to have a pleasant feel when applied to hair, not to cause the treated hair to frizz even under high humidity conditions, and to have excellent humidity resistance, etc. In particular, the prior art disclosed in Patent Documents 1 and 2 has not been particularly effective in suppressing hair frizz under high humidity conditions. Furthermore, compositions containing polyion complexes are available in the form of oil-in-water or water-in-oil emulsion compositions, but the improvement of the stability over time of these emulsion compositions has been an issue. In particular, hair cosmetic compositions may contain cationic surfactants, higher alcohols, etc. to improve the feel of treated hair. However, the incorporation of these components into emulsion compositions containing polyion complexes has the problem of easily decreasing stability.
[0006] An object of the present invention is to provide a hair cosmetic composition that has a good feel when applied to hair, can suppress hair frizz under high humidity conditions, and is highly stable. [Means for solving the problem]
[0007] The present inventors have discovered that the above-mentioned problems can be solved by a hair cosmetic composition containing one or more polymers selected from the group consisting of cationic polymers and amphoteric polymers, an anionic polymer, a specified nonionic compound, a cationic surfactant, and a higher alcohol, wherein the total content of the two types of polymers is less than a specified value. That is, the present invention relates to the following. Component (A): one or more polymers selected from the group consisting of cationic polymers and amphoteric polymers; Component (B): anionic polymer, Component (C): one or more nonionic compounds selected from the group consisting of polyglycerin and its derivatives, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, and glycerin fatty acid esters, each having an HLB value of 1 or more and 5 or less; Component (D): a cationic surfactant, and Ingredient (E): higher alcohol, wherein the total content of component (A) and component (B) is less than 1.0% by mass. [Effects of the Invention]
[0008] According to the present invention, it is possible to provide a hair cosmetic composition that has a good feel when applied to hair, can suppress hair frizz under high humidity conditions, and is highly stable. DETAILED DESCRIPTION OF THE INVENTION
[0009] [Hair cosmetic composition] The hair cosmetic composition of the present invention (hereinafter also simply referred to as "the composition of the present invention") is Component (A): one or more polymers selected from the group consisting of cationic polymers and amphoteric polymers; Component (B): anionic polymer, Component (C): one or more nonionic compounds selected from the group consisting of polyglycerin and its derivatives, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, and glycerin fatty acid esters, each having an HLB value of 1 or more and 5 or less; Component (D): a cationic surfactant, and Ingredient (E): higher alcohol, and the total content of the component (A) and the component (B) is less than 1.0 mass %. By having the above-mentioned constitution, the hair cosmetic composition of the present invention has a good feel when applied to hair, can suppress hair frizz under high humidity conditions, and is highly stable. In this specification, "containing component X" also includes blending component X.
[0010] The reason why the hair cosmetic composition of the present invention exhibits the above-mentioned effects is not clear, but is thought to be as follows. The hair cosmetic composition of the present invention contains a polyion complex formed from component (A) and component (B). The polyion complex is an aggregate formed by the chemical and electrostatic interaction between component (A) and component (B). The polyion complex is poorly soluble in water, and a hydrophobic film can be formed by applying a hair cosmetic composition containing the polyion complex to hair. The formation of this hydrophobic film is thought to improve the feel upon application to hair and also improve humidity resistance. Furthermore, by setting the total content of component (A) and component (B) in the hair cosmetic composition to less than 1.0 mass%, it is believed that the stability will be good even in the form of an emulsion composition containing a polyion complex.
[0011] Furthermore, it is believed that component (C) contained in the hair cosmetic composition penetrates into the hair, thereby improving the hair's texture upon application and its ability to inhibit hair frizz under high humidity conditions. Depending on the type of nonionic compound, its incorporation into a hair cosmetic composition can reduce the stability of the emulsion in the composition, resulting in a decrease in viscosity and a deterioration in the emulsion's dispersion state. However, in the present invention, the use of a specific nonionic compound, component (C), is believed to prevent deterioration in the emulsion's dispersion state and maintain the composition's stability. Furthermore, the inclusion of components (D) and (E) in the hair cosmetic composition is believed to further improve the texture upon application to hair.
[0012] The hair cosmetic composition of the present invention is preferably in the form of an emulsion composition, and more preferably an oil-in-water emulsion composition from the viewpoints of stability of the composition and improved usability. Examples of product forms of the hair cosmetic composition include hair shampoo, hair rinse, hair conditioner, hair treatment (including leave-in type), hair styling agent, etc. Among these, from the viewpoint of the effectiveness of the effects of the present invention, hair conditioner, hair treatment, or hair styling agent is preferred. Each component contained in the hair cosmetic composition will be described below.

The cationic polymer of component (A) preferably refers to a polymer having cationic groups and substantially free of anionic groups and amphoteric groups. The term "substantially free of anionic groups and amphoteric groups" means that the molar ratio of anionic groups and amphoteric groups to cationic groups is preferably 0.1% or less. The amphoteric polymer of component (A) is preferably a polymer having cationic and anionic groups, a 1% aqueous solution of which has a pH of less than 5.1 at 25° C., and a total positive charge on the polymer.

[0113] (Method for producing hair cosmetic composition) The method for producing the hair cosmetic composition is not particularly limited. However, when the hair cosmetic composition is an emulsion composition, it is preferable to produce a hair cosmetic composition that has a good feel when applied to hair, can suppress hair frizz under high humidity conditions, and is highly stable, by a method including the following step (1) and either step (2-1) or step (2-2): Step (1) A step of preparing a mixture A containing component (A), component (B), an organic acid, and water. Step (2-1): A step of preparing emulsion (I) by mixing the mixture A with oil phase components including components (C) to (E). Step (2-2) A step of preparing emulsion (II) by mixing oil phase components including components (C) to (E) with aqueous phase components other than mixture A, and then mixing mixture A. Components (C) to (E) are emulsion-forming components, and "oil phase components including components (C) to (E)" refer to oil phase components including emulsion-forming components. In this specification, "aqueous phase components" refer to components that constitute the aqueous phase in the production process of an emulsion composition, and "oil phase components" refer to components that constitute the oil phase in the production process of an emulsion composition.
[0114] <Step (1): Preparation of Mixture A> In step (1), the components (A), (B), an organic acid, and water are mixed to prepare a mixture A (aqueous phase component) containing the components (A), (B), an organic acid, and water. By performing step (1), a mixture A containing a polyion complex formed from the components (A) and (B) is obtained.
[0115] In preparing mixture A, the order of mixing component (A), component (B), organic acid, and water is not particularly limited, and for example, component (A), component (B), and organic acid may be added to water at the same time and mixed. From the viewpoint of ease of forming a polyion complex and of forming a more homogeneous polyion complex in water, it is preferable to first add component (A) and organic acid to water and mix them, and then add component (B) and mix them.

When the mixture A in the form of a suspension is used in step (2-1) or (2-2), the polyion complex remains stable in the resulting emulsion composition, which is believed to further improve the stability of the emulsion composition, the feel upon application to hair, and the effect of suppressing hair frizz under high humidity conditions.

The amount of organic acid used in preparing mixture A in step (1) may be a portion of the organic acid contained in the resulting composition.
[0122] In mixture A, the mass ratio of the total amount of components (A) and (B) to the amount of organic acid [(A+B) / organic acid] is preferably in the range of 1 / 0.10 to 1 / 20, more preferably 1 / 0.15 to 1 / 15, even more preferably 1 / 0.20 to 1 / 10, still more preferably 1 / 0.20 to 1 / 8, and even more preferably 1 / 0.22 to 1 / 4, from the viewpoints of facilitating the preparation of mixture A in suspension form, improving the feel when applied to hair, and suppressing hair spread under high-humidity conditions.

[Example]
[0145] The present invention will be described below with reference to examples, but the present invention is not limited to the scope of the examples. Measurements and evaluations in the examples were carried out by the following methods.
[0146] (pH measurement) Water was added to each hair cosmetic composition (hair conditioner) to prepare a 5% aqueous solution, and the pH was measured at 25°C using a pH meter (F-51, manufactured by Horiba, Ltd.) to find that the pH was 3.4 in all cases.
[0147] (emulsified state) 1 g of each hair conditioner was dropped onto a black plastic underlay, and the appearance and feel of the hair after being rubbed with a finger 10 times were evaluated according to the following criteria. A: No agglomerated particles are visible, and the surface feels smooth when you run your finger over it. B: No visible agglomerated particles, but they feel rough when rubbed with a finger C: Agglomerated particles are visible and feel rough when rubbed with a finger D: Separated
[0148] (Storage stability) The storage stability of each hair conditioner was evaluated by a cycle test. A cycle test was carried out in which each hair conditioner was stored for two weeks in an environment where the temperature changed between 40°C and -28°C. The daily temperature cycle was set to four cycles per day with a temperature difference ΔT of 40°C. After storage, the hair conditioner was visually observed for the presence or absence of separation, and in the table, those that were stable and did not separate were marked with an "A", and those that separated were marked with a "D".
[0149] (Feel when applied) A bleaching agent (a mixture of 7 mL of Kao Foam Hair Bleach L (1st liquid) and 14 mL of Kao Foam Hair Color d (2nd liquid)) was applied to a 30 cm long, 20 g mass Japanese hair tress, left to stand for 20 minutes, and then rinsed thoroughly with warm water at 35-40°C. The above process was repeated four times to prepare a Japanese damaged hair tress for evaluation. 1 mL of each hair conditioner was applied to the evaluation tresses and rubbed in with the hands. Five expert panelists evaluated the feel of the conditioner on a 5-point scale according to the following criteria, and the average value was used as the evaluation result. 5: Very smooth 4: Smooth 3: Somewhat smooth 2: Smoothness is equivalent to that of using plain conditioner with the following composition 1: It quickly loses presence and is not smooth

[0151] (Hair resistance to humidity after treatment) 1 mL of each hair conditioner was applied to the evaluation tresses of damaged Japanese hair prepared by the above method and allowed to soak in for 30 seconds. After leaving it in this state for 1 minute, it was rinsed with running water for 30 seconds and dried completely with a hair dryer. After drying, the tresses were straightened 10 times using a flat iron ("AHI-938" manufactured by Miki Electric Industrial Co., Ltd.) set to 160°C while passing the comb through, and a photograph of the tresses was taken immediately after setting. Next, the straightened hair was hung and left to stand in a high humidity environment of 35°C and 80% RH for 30 minutes, and then photographed again. In the two photographs, the tress width was measured at a point 23.5 cm from the root of the tresses, and the change in the tress width immediately after straightening and after storage in high humidity was calculated using the following formula. Change in trace width = (trace width after storage under high humidity) / (trace width immediately after straightening) If the value exceeds 1.3, the film appears to have spread visually, and therefore the film is judged to have low moisture resistance.
[0152] Example 1 (Preparation and Evaluation of Hair Conditioner) Using the ingredients listed in Table 1, hair conditioners were prepared according to the following procedure. In a 500 mL beaker, 1.52 g of polyquaternium-6 solution (component (A)), 3 g of lactic acid (90% by mass), and 419.7 g of water were placed, and the mixture was heated and stirred at 80° C. using a stirring device (a mechanical stirrer equipped with two propeller blades). After confirming that a homogeneous solution had been formed, 0.37 g of sodium polyacrylate (component (B)) was added and mixed to obtain mixture A, which was a homogeneous suspension (step (1)). Next, a hair cosmetic composition (hair conditioner) was prepared according to the following procedure. First, 1.5 g of polyglycerin (component (C)), 11.0 g of stearoxypropyldimethylamine (component (D)), 31.9 g of stearyl alcohol (component (E)), 2.5 g of benzyl alcohol (component (F)), and 10.0 g of dipropylene glycol (component (G)) listed in Table 1 were mixed in advance and heated and dissolved at 75°C to prepare an oil phase component containing components (C) to (E) (emulsion-forming components). This was added to mixture A, and the mixture was heated and stirred at 75°C for 10 minutes. After stirring for 10 minutes, heating was stopped and air cooling was initiated (preparation of emulsion (I)). Next, the oil (10.0 g of dimethicone and 5.0 g of lanolin fatty acid) which is component (I) and the remaining amount of lactic acid (3.50 g, 90% by mass) shown in Table 1 were added, and the mixture was cooled with stirring until the liquid temperature reached 40°C or below, thereby obtaining 500 mL of a hair conditioner (step (2-1)). The obtained hair conditioners were evaluated using the above-mentioned methods. The results are shown in Table 1. The blending amounts shown in the tables of this example are the blending amounts (mass%) of each component in its natural form, and the "active content" shown in the tables of this example is the content or blending amount (mass%) of each component converted into the amount of active ingredient.
[0153] Examples 2 to 25, Comparative Examples 1 to 8 Hair conditioners were produced and evaluated in the same manner as in Example 1, except that the types and amounts of each component used in preparing the hair conditioners were changed as shown in Tables 1 to 3. The results are shown in Tables 1 to 3.
