Description

[Technical Field]

[0001] The present invention relates to an aqueous cosmetic composition for hair. [Background technology]

[0002] BACKGROUND ART Oily hair cosmetics containing wax, higher alcohols, etc. have been known as hair cosmetics used to straighten bedhead, frizz, waves, etc., and to set hairstyles. However, although oily hair cosmetics can impart manageability to hair and prevent dryness, they also have a sticky feel, resulting in a heavy and unnatural finish overall.

[0003] For this reason, aqueous hair cosmetics that use water as a dispersion medium have been proposed (see, for example, Patent Document 1 or Patent Document 2).

[0004] However, in aqueous hair cosmetics, synthetic resins such as acrylic resins and amphoteric resins are generally used to provide styling power (setting power), and although this produces a light finish, it has technical issues such as an unpleasant feel, unnatural roughness and stiffness, and the hair is not smooth to run your fingers through, causing damage to the hair, making it poorly blendable with the hair, and making it difficult to eliminate dryness.

[0005] Furthermore, both oil-based and aqueous hair cosmetics have had the technical problem that they cannot provide sufficient hair styling effects unless heat treatment is performed using a hair dryer, hair iron, or the like during hair styling. [Prior art documents] [Patent documents]

[0010] According to the present invention, it is possible to provide an aqueous hair cosmetic composition that has an appropriate hair styling power (setting power) that can straighten bedhead, flyaways, waves, etc. to a natural finish, that is excellent in compatibility with hair, that reduces dryness and stickiness, and that can be used quickly and easily without the need for heat treatment with a hair dryer, hair iron, etc. when styling hair. DETAILED DESCRIPTION OF THE INVENTION

[0011] The aqueous hair cosmetic composition according to the present invention is characterized by containing (A) gum arabic, (B) hydrolyzed rhizobian gum, (C) an amphiphilic ester, and (D) water.

[0012] The aqueous hair cosmetic composition according to the present invention contains (A) gum arabic.

[0013] (A) Gum arabic is a secretion obtained from the stems and branches of Acacia senegal (L.) Willd. (Leguminosae) or other related plants. (A) Gum arabic is composed of the sugars galactose, arabinose, rhamnose, and glucuronic acid, and contains a small amount of protein. Senegal gum arabic is known to have excellent emulsifying properties, and its chemical structure is thought to be a β-1,3-linked galactose main chain with numerous branches, with galactose, arabinose, rhamnose, and glucuronic acid attached to the C6 position of the main chain. The above (A) gum arabic is easily dissolved in (D) water to form a low-viscosity aqueous solution, and therefore, when blended into an aqueous hair cosmetic, it is possible to provide an aqueous hair cosmetic with a lower viscosity than when other polymeric polysaccharides are blended.

[0014] The aqueous hair cosmetic composition of the present invention contains (A) gum arabic as well as (B) hydrolyzed rhizobian gum, which will be described later, and therefore forms a flexible film on the hair during use. Compared to hair styling products that use conventionally known film-forming agents, the composition does not overly stiffen the hair and reduces stickiness, while providing excellent hair manageability, preventing frizz and dryness, and exhibiting excellent styling power (setting power), resulting in a natural finish.

[0015] The aqueous hair cosmetic composition according to the present invention preferably contains (A) gum arabic in an amount of 0.08 to 4.50 mass %, more preferably 0.10 to 3.00 mass %, and even more preferably 0.30 to 1.00 mass %.

[0016] The aqueous hair cosmetic composition of the present invention contains (A) gum arabic within the above range, and therefore, while suppressing hair stickiness, it also provides good hair manageability, prevents frizz, and suppresses dryness, making it easy to achieve excellent hair styling power (setting power).

[0017] In the aqueous hair cosmetic composition of the present invention, if the content of (A) gum arabic is less than the above-mentioned lower limit, it becomes difficult to obtain sufficient hair styling power (setting power), and if the content of (A) gum arabic exceeds the above-mentioned upper limit, the composition becomes sticky, and the feel and sensation in use are likely to be deteriorated.

[0018] The aqueous hair cosmetic composition according to the present invention contains (B) hydrolyzed rhizobian gum.

[0019] (B) Hydrolyzed rhizobian gum is obtained by further hydrolyzing rhizobian gum, i.e., polysaccharides obtained by fermenting sugars derived from corn or the like with Rhizobium root nodule bacteria, with an acid or enzyme.

[0020] The aqueous hair cosmetic composition of the present invention contains (A) gum arabic and (B) hydrolyzed rhizobian gum, and therefore forms a flexible film on the hair during use. Compared to hair styling products that use conventionally known film-forming agents, the composition does not overly stiffen the hair and reduces stickiness, while providing excellent hair manageability, preventing frizz and dryness, and exhibiting excellent styling power (setting power), resulting in a natural finish.

[0021] The aqueous hair cosmetic composition according to the present invention preferably contains (B) hydrolyzed rhizobian gum in an amount of 0.01 to 1.25% by mass, more preferably 0.02 to 1.00% by mass, and even more preferably 0.05 to 0.50% by mass.

[0022] The aqueous hair cosmetic composition of the present invention contains (B) hydrolyzed rhizobian gum within the above range, so that it can easily exert excellent hair styling power (setting power) by suppressing hair stickiness while providing good hair manageability, preventing spread and dryness.

[0023] In the aqueous hair cosmetic composition of the present invention, if the content of (B) hydrolyzed rhizobian agam is less than the above lower limit, it becomes difficult to obtain sufficient hair styling power (setting power), and if the total content of (B) hydrolyzed rhizobian agam exceeds the above upper limit, the composition becomes sticky and the feel and sensation of use are likely to be impaired.

[0024] The aqueous hair cosmetic composition according to the present invention preferably contains (A) gum arabic and (B) hydrolyzed rhizobian gum in a total amount of 0.10 to 5.00 mass%, more preferably 0.15 to 4.00 mass%, and even more preferably 0.35 to 1.50 mass%.

[0025] The aqueous hair cosmetic composition of the present invention contains (A) gum arabic and (B) hydrolyzed rhizobian gum in the above-mentioned proportions in total, thereby suppressing hair stickiness while improving hair manageability, preventing frizz and dryness, and making it easier to achieve excellent hair styling power (setting power).

[0026] In the aqueous hair cosmetic composition of the present invention, if the total content of (A) gum arabic and (B) hydrolyzed rhizobian agam is less than the above-mentioned lower limit, it becomes difficult to obtain sufficient hair styling power (setting power), and if the total content of (A) gum arabic and (B) hydrolyzed rhizobian agam exceeds the above-mentioned upper limit, the composition becomes sticky and the feel and sensation of use are likely to be impaired.

[0027] In the aqueous hair cosmetic composition of the present invention, (A) gum arabic and (B) hydrolyzed rhizobian agam can be appropriately selected from commercially available products, such as EasyLiance (registered trademark) 2.0 (manufacturer: Givaudan SA), which is a mixture of (A) gum arabic and (B) hydrolyzed rhizobian agam.

[0028] When the aqueous hair cosmetic composition of the present invention contains EasyLiance (registered trademark) 2.0 as (A) gum arabic and (B) hydrolyzed rhizobian gum, the aqueous hair cosmetic composition of the present invention preferably contains 0.10 to 5.00 mass %, more preferably 0.15 to 4.00 mass %, and even more preferably 0.35 to 1.50 mass % of EasyLiance (registered trademark) 2.0.

[0029] The aqueous hair cosmetic composition according to the present invention may further contain, in addition to (A) gum arabic and (B) hydrolyzed rhizobian gum, other conventionally known film-forming agents, as long as the effects of the present invention are not impaired. The other film-forming agent may be, for example, one or more selected from pullulan, xanthan gum crosspolymer, and the like. When the aqueous hair cosmetic composition according to the present invention contains the other film-forming agents, the content thereof is preferably 0.01 to 10.00% by mass.

[0030] The aqueous hair cosmetic composition according to the present invention contains (C) an amphiphilic ester.

[0031] In the present application, (C) amphiphilic ester means an ester that dissolves at 10% by mass or more at room temperature in ion-exchanged water adjusted to a conductivity of 70 to 110 μs / m, as measured by the method specified in the general testing methods of the Japanese Pharmacopoeia, and also dissolves at 10% by mass or more in the oil agent isotridecyl isononanoate (Salacos 913, manufactured by The Nisshin Oillio Group, Ltd.) at room temperature (25°C).

[0032] In the aqueous hair cosmetic composition according to the present invention, the amphiphilic ester (C) may be an ester of a dicarboxylic acid with ethoxyethanol or ethoxydiglycol. More specifically, the compound may be one or more selected from diethoxyethyl succinate represented by the following formula (1), bisethoxydiglycol succinate represented by the following formula (2), and bisethoxydiglycol cyclohexane-1,4-dicarboxylate represented by the following formula (3), and is preferably one or more selected from bisethoxydiglycol succinate and bisethoxydiglycol cyclohexane-1,4-dicarboxylate.

[0033] [ka]

[0034] The aqueous hair cosmetic composition according to the present invention contains (C) an amphiphilic ester, which improves compatibility with hydrophobic hair and easily exerts sufficient hair styling power (setting power).

[0035] The aqueous hair cosmetic composition according to the present invention preferably contains 0.10 to 5.00 mass %, more preferably 0.50 to 4.00 mass %, and even more preferably 1.00 to 3.00 mass % of the amphiphilic ester (C).

[0036] The aqueous hair cosmetic composition according to the present invention contains (C) the amphiphilic ester within the above range, thereby easily improving compatibility with hair and easily exhibiting sufficient hair styling power (setting power) even with a small amount.

[0037] In the aqueous hair cosmetic composition according to the present invention, if the content of (C) amphiphilic ester is less than the above-mentioned lower limit, the hair will repel the aqueous hair cosmetic composition, making it less compatible with the hair. On the other hand, if the content of (C) amphiphilic ester exceeds the above-mentioned upper limit, the aqueous hair cosmetic composition will become turbid, making it less stable (storage stability).

[0038] The aqueous hair cosmetic composition according to the present invention may contain a polyhydric alcohol in addition to the above-mentioned (A) gum arabic, (B) hydrolyzed rhizobian gum, and (C) amphiphilic ester.

[0039] In the aqueous hair cosmetic composition according to the present invention, the polyhydric alcohol may be one or more selected from the group consisting of ethylene glycol, propylene glycol, 1,3-butylene glycol, hexylene glycol, glycerin, diethylene glycol, triethylene glycol, polyethylene glycol, polypropylene glycol, polyglycerin, and the like.

[0040] The aqueous hair cosmetic composition according to the present invention contains a polyhydric alcohol, which can easily improve the moisturizing properties of hair. The aqueous hair cosmetic composition according to the present invention preferably contains 1.00 to 20.00 mass %, more preferably 3.00 to 15.00 mass %, and even more preferably 4.00 to 10.00 mass % of polyhydric alcohol.

[0041] By containing a polyhydric alcohol within the above range, the aqueous hair cosmetic composition of the present invention can easily impart moisturizing properties to hair during use, and can easily improve the low-temperature stability of the aqueous hair cosmetic composition of the present invention.

[0042] Furthermore, in addition to the above-mentioned components, the aqueous hair cosmetic composition according to the present invention may contain, as appropriate, other components that are typically incorporated into cosmetics, such as alcohols, amino acids, vitamins, proteins, fatty acids, enzymes, humectants, surfactants, chelating agents, oils, hair growth agents, fragrances, colorants, preservatives, disinfectants, anti-inflammatory agents, antiperspirants, antioxidants, ultraviolet absorbers, animal extracts, organic powders, inorganic powders, pH adjusters, and viscosity adjusters, provided that the object of the present invention is not impaired.

[0043] The aqueous hair cosmetic composition according to the present invention contains (D) water.

[0044] In the aqueous hair cosmetic composition according to the present invention, the water (D) is not particularly limited as long as it is water that is normally used as a raw material for cosmetics, and examples thereof include one or more types selected from purified water, ion-exchanged water, tap water, etc.

[0045] The aqueous hair cosmetic composition according to the present invention uses water (D) as a dispersion medium, and therefore can easily suppress sticky feeling.

[0046] The aqueous hair cosmetic composition according to the present invention contains water as a dispersion medium, and the balance other than the above-mentioned components is water. The aqueous hair cosmetic composition according to the present invention typically contains (D) water in an amount of 50.00 to 99.00 mass %, preferably 60.00 to 95.00 mass %, and more preferably 70.00 to 90.00 mass %.

[0047] In the aqueous hair cosmetic composition of the present invention, the content of (D) water is within the above range, so that stickiness can be easily suppressed and excellent hair styling power (setting power) can be obtained without compromising the effects of containing other ingredients.

[0048] Many of the conventionally known hair cosmetics contain large amounts of hydrophobic components, and therefore if the cosmetic components are not rinsed off thoroughly, the cosmetic components will remain on the hair. However, the aqueous hair cosmetic of the present invention can be easily rinsed off because the essential component (C) amphiphilic ester is a water-soluble component, and the essential components (A) gum arabic and (B) hydrolyzed rhizobian gum are also water-soluble polysaccharides.

[0066] [Table 1]

[0067] [Table 2]

[0068] Tables 1 and 2 show that the aqueous hair cosmetics obtained in Examples 1 to 3 contain (A) gum arabic and (B) hydrolyzed rhizobian gum, and therefore, when used, can suppress (3) stickiness and (5) dryness of hair and provide excellent (4) manageability to hair. Furthermore, Tables 1 and 2 show that the aqueous hair cosmetics obtained in Examples 1 to 3 contain (A) gum arabic and (B) hydrolyzed rhizobian gum, and therefore can impart excellent (1) length to hair during use, and as described above, can provide excellent (4) manageability and suppress (5) dryness of hair (because the total score ((4) + (5)) of (1) length and (4) manageability and (5) dryness is high), and therefore can exhibit high hair styling power (setting power). Furthermore, Tables 1 and 2 show that the aqueous hair cosmetics obtained in Examples 1 to 3 contain (C) amphiphilic ester and are therefore capable of exhibiting excellent (2) compatibility with hair. As shown in Table 2, the total score of (2) to (5) (total score of (2) hair compatibility + (3) stickiness + (4) manageability + (5) dryness) calculated to comprehensively evaluate each of the above items also shows that the aqueous hair cosmetics obtained in Examples 1 to 3 are capable of exhibiting high performance. Furthermore, Tables 1 and 2 show that the aqueous hair cosmetics obtained in Examples 1 to 3 contain specific ingredients and therefore have (6) excellent stability (storage stability). In addition, the aqueous hair cosmetics obtained in Examples 1 to 3 were quick and easy to use, as they did not require heat treatment with a hair dryer, hair iron, or the like when styling hair.

[0069] On the other hand, Tables 1 and 2 show that the aqueous hair cosmetics obtained in Comparative Examples 1 to 3 do not contain (C) amphiphilic ester, and therefore (2) are poor in compatibility with hair. Furthermore, Tables 1 and 2 show that the aqueous hair cosmetics obtained in Comparative Examples 4 to 6 do not contain (A) gum arabic and (B) hydrolyzed rhizobian gum, and therefore, when used, they are less able to (4) manage hair and are prone to (5) dryness. Furthermore, Tables 1 and 2 reveal that the aqueous hair cosmetics obtained in Comparative Examples 4 to 6, which do not contain (A) gum arabic and (B) hydrolyzed rhizobian gum, are inferior in (1) elongation upon use, and as described above, are prone to (4) poor manageability and (5) dryness (due to the low total score for (1) elongation and (4) manageability + (5) dryness), resulting in poor hair styling power (setting power). Tables 1 and 2 also reveal that the aqueous hair cosmetic obtained in Comparative Example 6 is inferior in (6) stability (storage stability). Furthermore, the aqueous hair cosmetics obtained in Comparative Examples 1 to 6 required heat treatment with a hair dryer, hair iron, etc. during hair styling, making them difficult to use conveniently. Tables 1 and 2 show that the oily hair cosmetic preparation obtained in Comparative Example 7 does not contain (A) gum arabic, (B) hydrolyzed rhizobian gum, (C) amphiphilic ester, or (D) water, and therefore (3) is highly sticky. Furthermore, the oily hair cosmetic preparation obtained in Comparative Example 7 required heat treatment with a hair dryer, hair iron, etc. during hair styling, making it difficult to use conveniently.
